Catching Up: Signs Finished, Solar Stuff, Flowers Everywhere, Engraving Lighters, Silly Cats, No More Hip Pain Somehow?

MrsGF finished up the last of the welcome signs the other day with about three coats of all weather polyurethane. We did four all together. We’re keeping one and these three are already spoken for. They turned out pretty nice I think.

We hit a milestone with the new EG4-12000XP inverter. We hit half a megawatt of production earlier today! We’re going to need every watt we can get out of that system because the big central AC unit is still on the grid and it’s been going for something like 3 weeks straight now since we shifted into this hot weather pattern. We decided to leave it on the grid because while the 12000XP would have enough oomph to handle it, I suspect it would would discharge our batteries to a point where I would become uncomfortable overnight. It’s the old style AC system, but it’s only a few years old so replacing it isn’t in the cards at the moment. If we’d known better at the time we would have gone for a heat pump system which is much more energy efficient but at the time we weren’t even dreaming of putting in whole house solar. I looked into it but a heat pump system would have been around twice the cost so I never seriously considered it. Oh, well. Live and learn, as they say.

Our electric rate here isn’t bad, about 20¢/KWh, which is cheap when compared to what those poor buggers out in California are getting hit with thanks to Newsome and the California legislature being owned lock, stock and barrel by the utility companies and the hundreds of thousands of dollars of bribes… (cough cough), I mean “campaign donations” and lobbying $$ they pay out every year. But the handwriting is one the wall, as they say. Thanks to the huge amounts of power the massive data centers being built here in the state are gulping down now and will gulp down in the future, the utilities are going to have to invest hundreds of millions of dollars in new generating facilities, substations and high tension power lines to feed them, and you can be damned sure that if Microsoft, Meta, Oracle and the others building those facilities have anything to say about it, it’s going to be us consumers who are going to foot the bill, not them.

But on to a more pleasant subject. Laser engraving.

I had no idea but apparently Zippo lighters are still a thing with some people? I thought that with the rate of smoking going down every year the market for lighters would have shrunk as well but I guess I forgot about the people who smoke “recreational substances”, shall we call it? That’s still illegal here in Wisconsin but all you have to do is nip across the border to Illinois, Minnesota or Michigan if you want to light up.

I did the first one with the brewery logo on it to give to Kyle, one of the owners. And then I started playing around using the Lumos Flex from Wecreat and the fiber laser and wow, it does a nice job engraving stainless steel! Doesn’t take long, either. With the IR laser in my old Lumos it would have probably taken half an hour to do something like this. With the fiber laser it takes about 4 minutes. It actually eteches right into the metal so that design isn’t just discoloration, it’s actually etched in there and will never wear off. I’ve done about four of these for various people to give as gifts and they keep telling me I should put these up on Etsy or somewhere, but no thanks. I do not want to get into that rat race. Plain, genuine Zippo lighters cost me about $18 each. In order to make it worth my while I’d probably have to charge $35 – $40 for one and I don’t think anyone would be silly enough to pay that.

And then we got flowers! Wow, do we have flowers! Here are a couple.

As for the rest of the gardens I’m too lazy at the moment to go out and get pictures so you’ll have to settle for a description. The tomatoes are going gangbusters. They’re already loaded with green fruit. We have 6 plants this year. We were only going to put in 3 but we had 3 or 4 volunteers pop up and MrsGf didn’t have the heart to just pull them so she transplanted them to a better location and they’re looking just as good as the ones we grew from seed ourselves.

The carrots are thriving and we really need to thin them out. The beets? We’ve already been picking some and eating them. They’re doing fantastic. The celery is looking beautiful this year. When I’m mowing the lawn I can’t help but snip off a stalk to nibble on when I’m riding on the mower. If you’ve never grown celery yourself, please give it a try. You won’t believe how intensely flavored the home grown varieties are when compared to the commercial varieties they sell in the grocery store.

The onions are getting to the point where we’re thinking of starting to pull some and curing them off and putting them in storage.

We have a few zucchini plants as well and they’re producing beautifully. The nice thing about zucchini is that it has almost no flavor so you can slip it into anything and nobody will notice they’re eating something healthy. Tonight I’m going to do a zucchini-mushroom stir fry with lots of garlic and onions and parmesan cheese.

I’m eagerly awaiting the tomatoes. Absolutely nothing compares to the flavor of a ripe tomato fresh off the plant from the garden.

Let’s see, what else?

Oh, the hip! Almost forgot about that. I suffered for something like 3 weeks with pain in my right hip that was almost excruciating at times when I bent my leg the wrong way. It started to oh so slowly get better over time. But then the other day I woke up and got out of bed and suddenly realized that the hip didn’t hurt. At all. It was like someone just threw a switch. There’s a bit of soreness there but that’s because the muscles in the leg are stiff from not being used normally for so long.

So what happened? I have no idea. MrsGF thinks it might have been a pinched nerve and I suppose that’s possible?

Anyway, I’m still taking it easy because I’m terrified of doing something that might bring it back. But otherwise things are back to almost normal. I’m even back on the bike again but I’m keeping the riding limited to just a few miles and at a relatively slow pace for the time being.

Let’s see… Oh, almost forgot! Silly cats, right?

That’s Charlie over there in her new favorite stot to sit. If I scoot forward to type on the computer and there is any space at all between me and the back of the chair, she’ll squeeze in there. She is an absolute sweetie. I’ve never seen a cat that loves people as much as she does. She belonged to our daughter in law’s aunt but she had to move into an apartment that doesn’t allow pets so we volunteered to take her in and we’re so happy we did. She’s getting up there, about 14 or 15 years old now, and she has a heart murmur and a benign cyst on her neck that puts some people off but doesn’t seem to bother her at all. The cyst is inoperable because she can’t tolerate anesthesia. They tried once and her heart stopped and she almost died so unless it’s a genuine emergency neither we nor her vet are willing to try it again.

And that’s about it for now!

Hm? Oh, oh, wait… Oh no… That’s not a 3D printer on a truck heading this way, is it? No, it couldn’t be. I swore I’d never buy another one, didn’t I? I seem to distinctly remember saying that, didn’t I?

It’s Iris Time! Plus Assorted Stuff!

Yes, it’s iris time again. If you’ve been following this blog for a while you must know by now that I absolutely love irises. We have a whole garden devoted almost excolusively to irises. And they’re just coming into full flower now. Here are a few photos from earlier today.

And for no reason at all, here’s a silly cat image I stole borrowed from Pete over at https://beetleypete.com/ If you enjoy posts from a retired English gentleman who occasionally puts up very silly images, posts some delightful fiction and chats about life in general in the small town of Beetley, in Norfolk, go check it out. He is a lovely, gentle soul, with a wry sense of humor.

Other stuff:

Meanwhile I’ve been working on this…

It is, heaven help me, a cat riding a T-Rex through the deserts of Utah. Thats going to be engraved on a 37cm X 25cm panel inlaid into a gift box MrsGF is making. Sometimes the stuff I come up with when I sit down with Photoshop makes me wonder what’s wrong with my brain. But never mind.

BTW: If any of you out there would be interested in that image up there let me know and I could make it available for downloading here. I think. Maybe. It would be as a standard .PNG file that would be suitable for importing into a laser engraver. If you’re interested let me know at theoldgrouch@grouchyfarmer.com. I never really intended to set this up to download files but if people are interested in stuff like this I’d probably set up a separate page here with just a listing of downloadable files for laser cutting/engraving.

If you have comments or questions you can reach me at that email address as well.

Weather

The weather has been, well, odd, to say the least. Over in Two Rivers about 20 or s0 miles from here where friends of ours live, they had an intense and highly localized storm that leveled half the trees in the city the other day. Parts of the town were without power for three days. They estimate they had straight line winds up to 80 mph. Meanwhile just a few miles away they got nothing but some rain.

Temperatures have been highly erratic here. One day we have a high in the 50s, the next it can be well over 80. Yesterday it hit 92 here. Now it’s getting cooler and we might struggle to hit 65 by the end of the week. They were predicting thunderstorms last night but those fizzled out before they even really got started. We got about a tenth of inch of rain and that was it.

It’s very, very dry out there. We’re going to have to start watering the gardens already tomorrow.

Weather patterns are changing drastically all around the world. I have friends and family scattered around the globe and what I hear from them is often downright frightening. In India where my niece’s husband’s family is from, this May has been one of the warmest on record with temperatures pushing 113F in Delhi. One of my best friends lives in Barcelona half the year and they’re seeing temperatures pushing up to 100F or beyond. Even in the UK temperatures have been pushing up into the 90s.

Farming

With a name like grouchyfarmer I suppose I should talk about the ag industry at least briefly. Even though I’ve wandered far away from farming long ago and have dabbled in everything from writing to electronics to arts and crafts, I’m still a farmer at heart and what I see going on out there in the ag world is heartbreaking. Especially since all of the problems farmers are having right now are due entirely to decisions being made by power mad, greedy politicians who only care about enriching themselves and clinging desperately to their little bits of power and influence.

Farm bankruptcy rates are up by 50% or more in the last year, and look like they’re going to get even worse as time goes on.

Diesel, the fuel farmers use in their equipment, has gone up more than 60%, from about $3.47 to $5.60. Even as high as $7.50 in some places like California.

Fertilizer prices have spiked up 61% as well, and exactly at the wrong time when planting season is here and young plants need to be fertilized to get strong growth.

Meanwhile prices farmers get for two of their primary crops, corn and soybeans, have plummeted to the point where it looks like most farmers around here aren’t even going to be able to break even.

Dairy farmers are doing a bit better, but they have problems too. I know some farmers around here who are working 18 hour days because all of their hired help basically packed up and fled, even if they were in the country legally. Word is out that if you’re Hispanic, even if you’re in the country legally, you’re going to be swept up, detained for weeks if not months, and probably end up deported even if you have a green card. We used to have a fairly large number of Hispanic families here in town. Wonderful people who were hard working, honest, friendly and becoming part of the community. They’re all gone. All of them.

It’s going to be a hard year for farmers around here. A very hard year. And the tragic part of it is that this is 100% the fault of that bunch of sniveling, greedy, power mad politicians in DC. And I mean both political parties are at fault here. Democrats and Republicans both are more concerned with maintaining their little bits of power, trying to suck up ever more money from corporations and oligarchs through this system of legalized bribery we call a campaign financing system, that they’ve entire forgotten that they are supposed to be the representatives of the people in their home districts.

Okay, rant over. I swore I was not going to get political here in this blog and for the most part I’ve kept that promise. But when I see the sheer crap that is going on in Washington and here in Madison in the state legislature… Never mind. Enough.

Astronomy

It’s been so long since I talked about it here that you’ve probably forgotten that I’m also an amateur astronomer. That’s one of my telescopes down there, my 11″ Celestron.

I’ve reached a point in my life where I just have too many interests and hobbies and I’ve started to do a bit of triage. I’ve pushed aside some things like tinkering with electronics and a few other things to have more time to devote to the things I enjoy the most. So I’m able to spend more time with photography, art, the whole engraving thing and yes, astronomy.

My interests have changed a bit over the years. I’ve become more interested in astrophotography than in direct visual observation, especially photography of deep sky objects. The Celestron is a fantastic telescope but there are “issues”. It’s size and weight are one. That sucker is big and it is heavy. The optical tube assembly weighs in at around 60+ pounds and I’m not exactly a spring chicken any more. Trying to maneuver that thing up and down the stairs, getting it set up on its mount, etc, well I’m just not physically capable of wrestling with that thing without risking dropping $5,000 telescop down the back stairs. So it’s gone to live with my eldest son who is planning on using it as the core for a fixed observatory set up in his back garden with a small building with a roll off roof, concrete pier, power, internet, etc.

Meanwhile I have a new telescope on order that should be here by June 7, they tell me.

And as you can see, it is something entirely different from the Celestron. It doesn’t even look like a telescope to be honest. For one thing it is exclusively an astrograph telescope, it does photography only. It doesn’t permit visual observation at all. In fact I don’t even have to be near it to operate it. It is controlled by a tablet computer or app on a cell phone via WiFi or bluetooth so I no longer have to endure the clouds of mosquitoes that we get around here. Just set it up after dark, turn it on, and then sit in my nice, air conditioned house controlling it entirely by computer from the kitchen table. Or if I take it out to my sister in law’s farm to get away from the light pollution, from inside of my car.

I admit that I’m taking a bit of a chance here. I find it hard to believe that a scope this small and this cheap can get the results I see in the reviews of this thing. Supposedly this thing can get good images of even difficult deep sky objects like the Horse Head nebula in just a few minutes, even in relatively poor conditions. And it’s only about $600 compared to around $5,000 for something like my Celestron. It sounds too good to be true.

After I’ve had a chance to get it set up and have figured out how to use it, I’ll talk about it more.

Anyway, that’s it for now. Time for me to get out of here!

Catching Up: Spring, solar, lasers, Oh My

Well it’s spring, or so they tell me. And judging from the lack of posts here it seems I’ve been hibernating most of the winter, doesn’t it?

After a ridiculously warm winter we’ve had a ridiculously cold spring. It isn’t until now, early May, that we’ve gotten reasonably warm temperatures during the day, although it’s still plunging down to near freezing at night. Anyway, the daffodils are in full bloom, even some of the irises are popping open which is always delightful to see.

MrsGF has had her seedling operation going in the basement for some time already. We have tomatoes, brussel sprouts, peppers and I don’t know what all else popping up in the little greenhouse down there. We have onion sets ready to go out as soon as the weather improves. The garlic she planted seems to be thriving. She only put in about a dozen garlic cloves and somehow all of them seem to have survived the winter and are now about 8 inches tall out behind the garage near the solar panels.

If you’ve been following this blog for a while you know I love bicycling, and by this time of year I should have been going out almost every day. But thanks to the cold weather that hasn’t been happening. I’ve managed to get out exactly twice since mid-April. It is very frustrating.

Solar Stuff

I think I mentioned that I picked up a bunch of solar panels with the intention of getting them up on the roof of the garage to supplement my rather pathetic 2KW of panels leaning up against the back of the house. Alas, that hasn’t happened either because of the poor weather. Hopefully soon. MrsGF has a fit when she sees me up on a ladder or on a roof, so getting those mounted is going to have to depend on when my sons can get over here to work on it. And I suppose I better actually order the mounting hardware, shouldn’t I?

I just got done completely rewiring the entire AC side of the solar power system to bring it up to snuff so it will pass an inspection. It’s configured a bit differently this time. The inverters struggled to keep the central air conditioning running, to the point where we couldn’t run on solar if we had to use the AC. That meant that whenever the weather got hot, we were entirely on the grid, which was not a good thing. The system has been rewired now so that both the AC and the electric clothes dryer are always connected to the grid while the rest of the house can be switched over to the solar system. So we’ll be able to keep cool and do laundry while running the rest of the house off solar.

Also this brings the system into compliance with electrical codes and it’s passed inspection.

Laser Stuff

This is one of the reasons why I’ve been so busy that blog posts have been neglected. If you’ve been following grouchyfarmer for a while, you know that I’m sort of an artist/electronics geek/computer geek/maker/… Well, you get the idea I suppose. Years ago I got a deal on a cheap, flat bed laser engraver. While it was fun to play with, it was also woefully slow, cranky, fiddly, annoying, had zero safety equipment, zero smoke control, inaccurate, but fun.

And it sparked some ideas as well. Commercial ideas that eventually developed into actual products. I eventually got a much better, much faster, much more accurate and much more useful laser, and I started cranking out things like company logos, art projects, things like that. I didn’t do a lot of it because despite what you may see on YouTube, there really isn’t any actual money in doing this kind of thing unless you’re willing to invest the time, money, and especially the equipment, into going into it almost at an industrial scale. What mattered to me was that I was enjoying it, it gave me an outlet for this need I had for artistic expression and all that high minded guff, and it gave me an excuse to play with a lot of high tech equipment.

I thought that part of my life was pretty much done with, though. I was getting a bit tired of it. Technology was moving on, if I was going to continue doing it I was going to have to get serious about learning Photoshop and Adobe Illustrator at a level that was deeper than I really wanted to get involved with. And to top it off my laser engravers were starting to show their age.

And then stuff started happening. People I’d made things for before started asking about doing more, the brewing company told me that all of the joke coasters I’d done for them had been stolen and they wanted more and oh, could I look into doing a few promotional items for them like maybe branded keyfobs or bottle openers. And then I was getting the urge to make “art” again…

Okay, to make a long story short, i got a new laser engraver/cutter and I’m back in the business again. And yes I’m going to bore you with all of the details, but not in this post. I’ll reserve that for a different time because to cover everything I want to talk about is going to take some space.

That’s about it for now. It’s actually nice out today, so I’m heading out to put a few miles on the bike.

Photoshop, generative AI and art. And a few observations.

I’m a photographer and artist (well, sort of an artist), among other things. While I am strictly an amateur at both, I’ve been using Photoshop for something like 20 years for editing photos, sketching, cartooning, etc. And I have some concerns about what’s going on in the world of photography and art. Let me give you an example.

Look at the photo over there on the left. It’s a fairly generic looking and pleasant image of an attractive young woman. A woman who doesn’t actually exist. That image was created a few minutes ago using Photoshop Beta with Adobe’s generative AI technology. As you can see, generative AI has become very, very good. Scary good, really.

Well okay there are still some “issues”, as they say. Let me who you the entire image that Photoshop came up with when I told it to generate a photograph of two women in a coffee shop.

See the problem? The young lady must really, really like her coffee. Or look at this one, which is another image generated using the same text description.

Generative AI may be very, very good, but it isn’t actually all that smart.

Let me show you another image. This one was generated with the exact same text description but this time I told it to produce a black and white line drawing. This is what it came up with.

Not the best artwork in the world but perfectly acceptable for a simple drawing. I’ve seen a heck of a lot worst human created artwork. And better still, no weird glitches with cups or hands. I got this one when I tried generating another line drawing with the same text description.

I’m sure you see the problem there. Adobe’s AI, and in fact almost all of the ones I’ve experimented with, all seem to have trouble dealing with hands for some reason.

Now, did you notice something else interesting about those images? All four images depict young Black women even though I did not specify a particular ethnicity in the description I typed in. I found this rather curious so I continued. Eventually I generated 20 different images using the same text description. Of those 20 images, 10 depicted Black women, 3 depicted women of Middle Eastern ethnicity, 4 were Asian, one was Indian and 3 were caucasian.

I found this rather curious. The same was true, although to a lesser extent, when I generated images of men. Don’t get me wrong. I’m not upset. In fact I find this rather refreshing because often we’re bombarded with images of nothing but white people in a lot of the videos, advertising, stock photography, etc. that we’re forced to endure every day.

But sometimes the images are a bit – well a bit disturbing. I asked it to come up with a line drawing of a couple sitting in a pub having a beer and this is what it came up with.

Oh, dear… Yeah, seriously. This is what it thinks a young couple in a pub looks like.

Just for the heck of it I added a specification that it should generate an image of a white couple and this is what it came up with.

Oh, dear again. Why does she have a pepper grinder glued to her head? Why is he dipping spaghetti in his beer?

But it also comes up with some stuff that is surprisingly good. I told it to generate an image of a grouchy old farmer leaning on a split rail fence watching a herd of grazing cows and it came up with this.

Not bad, really. Well, if you don’t look at his left had too closely.

For the heck of it I switched from photography to painting and it came up with this from the same prompt.

I actually like that one, to be honest. I would print that out in large format, put it in one of those overpriced tourists shops up in Door County and someone would probably pay actual money for that.

Which brings me to what I really want to talk about, and that is how AI generated artwork is going to effect society in general. We are already starting to see fundamental changes.

First, we’re going to see the end of stock photo providers ike Getty. Which is not necessarily a bad thing. Why would anyone bother to license stock images from companies like Getty when with a few words of description and Photoshop or one of the other AIs you can generate a generic illustration for your story or article? Let’s say you’re writing an article about vacations and you want to use a nice beach scene to illustrate it. So why go to a stock image company and buy the rights to use one when you can do this below with a few words and Photoshop?

Took all of about 15 seconds to generate that image from a one sentence prompt.

Stock image companies aren’t the only things that are going to come to an end. Would Normal Rockwell have ever gotten a job doing magazine covers in today’s world? I doubt it. I think illustrators in general are already losing their jobs, their work being done by AI. I’m seeing scores of images illustrating articles, fiction, even news stories, that look suspiciously like they were done by AI.

AI is already making inroads into the world of computer programming. There’s a very good chance that AIs are also already making significant decisions about you health care, not actual real doctors. The customer support person you chatted with on that website? Quite possibly an AI.

You may not like it. I don’t. Isn’t going to matter in the sightest. That horse is already out of the barn. Corporations can and will use AIs to replace human beings every place they can.

Your House’s Electrical System and Catching Up

grouchyfarmer.com is now written by an actual real human being, not an AI! Now featuring actual genuine typos, mysspelngs, and much, much more!

So, on Monday, May 1, this is what it looked like outside my front door at 5 AM.

Yes, that’s snow. Nice weather we get here. This is why I haven’t been talking about gardening and bicycling and drone flying and putting up photos of pretty flowers and all that stuff. We had two or three days of summer like weather in March with temperatures in the 80s, and ever since then it’s been like this… cold, wet, cloudly, and now snow. Welcome to Wisconsin. Sigh… The weather has since gotten a bit better. It’s still been so cloudy with occasional rain that we’ve been making pretty much zero solar power. Again, sigh… Of course I shouldn’t complain. I have a friend who lives about 100 miles north of here in the upper peninsula of Michigan and over last week or so he got 52 inches of snow.

What I wanted to talk about is that someone asked why I need two inverters bolted to the wall and not just one. Just one of those inverters can supply 6.5 KW of power, as much as my big Generac gasoline generator, and enough to run almost the entire house as long as we’re careful. So why do I need two of them?

Partly it’s a question of capacity. 6.5 KW is a bit close to the edge for us, so to speak, at least as far as normal daily life is concerned. We may complain about our electric bill but we do like appliances like our coffee makers, our convection oven, etc. With just one inverter there would be times we would be pushing over that 6.5 KW limit. Two inverters give us a comfortable cushion.

The biggest reason though is that we also need 240V power to run some of the appliances in the house. For that we need both inverters. Initially I’m not going to be hooking any 240 appliances into this system because I don’t have eno0ugh batteries and solar panels to handle it, but eventually that’s going to change so I wanted a system that could be switched over easily in the future.

WTF is 240V split phase?

The average person doesn’t know, and doesn’t need to know, what actually goes on in the electrical system of the house. As long as your toaster or computer or TV works when it’s plugged into the wall and the lights turn on when the switch is flipped, that’s all they care about. And for most people that’s fine. But if you want to switch your home to an alternative energy system you need to know what’s going on behind the scenes.

While most of the systems in your house run on 120 VAC, in all likelihood there are some that require more power than a normal 120V line can supply. Things like electric water heaters, clothes dryers, electric stoves, well pumps, etc. will often run on 240V, not 120. The amount of power these appliances require would overload the normal 120V wiring systems in the house. So let me explain what’s going on without this getting complicated.

Well it’s going to get complicated anyway but let’s see what I can do.

What you have coming into your house is two, 120V AC power lines, not one. The two lines can be combined inside your circuit breaker panel to give you 240V to power more power hungry appliances like HVAC systems and clothes dryers.

If you took the front panel off of the main circuit breaker panel in your house it would looks something like the one in the photo below.

Now you’ll notice a couple of things right away if you look at that photo up there carefully. Note that there are two rows of circuit breakers, not one. There is a reason for that and I’ll come to that in a minute.

The next thing I want you to look at is right at the top center of that picture. You’ll see three thick wires coming in from the top. One is black, the 2nd is marked with red tape, and the third runs off to the right of center and is marked with white. Those three lines are what comes in from the service panel attached to the outside of your house and which, in turn, is fed from the utility company. The black wire and the red are the two 120V lines coming into the house and the white is the neutral line.

In your panel are two metal strips called busbars that the two hot wires (sometimes called legs because why not) connect to. Each busbar runs the length of the panel. The circuit breakers in the panel connect to those busbars to get the power that they then send out to the wires that lead to the outlets, lights, etc. in your house.

The circuit breakers on the left side of the panel get their power from L1, and the ones on the right get their power from L2.. Each busbar provides 120V.

So how do you get the 240V? Look at the top of the right row of breakers and you’ll see what looks like two breakers that are joined into one by a bar that connects the two switches together. That’s a 240V breaker.

Well, sort of. It doesn’t actually give you 240V. What it does is tap into both of the busbars at the same times, and lets you run two, 120V hot wires to whatever device that breaker breaker powers. The appliance that circuit energizes can combine both to provide 240V or use the individual 120V lines to power individual circuits in the appliance.

So if you want to design an alternative power system to run your whole house through your existing electrical system, you need a system that provides 120V to both L1 and L2, a 240 split phase system as they call it. And no, I can’t just feed 120V from a single source into both busbars at the same time because L1 and L2 are 180 degrees out of phase with one another and that is important. Or so they tell me.

Okay, so what’s with this phase stuff? Well it gets even more complicated and there is a hell of a lot of misinformation out there about what’s generally called “240V split phase”. There are people out there who will try to tell you that you need 240V split phase to power two phase motors, only there really aren’t any two phase motors out there and there haven’t been in many, many years. Or they’ll tell you you need split phase for electronics which is total BS because almost all modern electronics run off DC not AC…

Okay, look, the reason you have split phase coming into your home… Oh, hell, let’s look at what they’re talking about first of all.

AC stands for alternating current, and it’s called that because it, well, alternates. It doesn’t provide a steady positive voltage the way DC does. It alternates from plus to minus at 60 cycles per second. If you were to hook an oscilloscope up to an AC power line what you’d see on the screen is something like what you see in the picture over there on the left.

If you could look at both L1 and L2 at the same time on an oscilloscope it would look something like the picture over there on the right. The two are 180 degrees out of phase.

Why do we even use this system? It would take me pages and pages to explain all of that so I’ll leave it to you to go scurry over to Wikipedia or somewhere and find out for yourself.

So you have two, 120V lines coming in your house and they are 180 degrees out of phase with one another. Sort of. Kinda. And that’s important for, well, reasons, all right? And the two lines can be combined to give you 240V to power bigger appliances. Or not.

Are you confused yet? I am.

But let’s get back to my setup here. Each of the inverters will supply 1 of the two hot lines needed to get 240. And the two inverters “talk” to each other over a communications line so their sine waves are 180 degrees out of phase when in the split phase mode. Which is important for, well, for reasons. Or so they tell me. That’s what we’re stuck with.

But at the moment I don’t want to run any of my 240V appliances off this system. First of all that equipment sucks up huge amounts of power which would drain my batteries fast. The second issue is that my central air conditioning system quite possibly would require more amperage than my batteries can supply. EG4 recommends having at least 5 batteries in order to supply enough amperage to start up a big HVAC system like mine and I only have 3 at the moment.

To make a long story a bit shorter, I have two inverters because I’ll probably almost certainly need a system that can provide more load capacity than a single inverter would give me, and I eventually may want to expand the system to get 240V if I ever get enough batteries and solar panels up to support it.

But I’ve bored you long enough with this. let’s get on with it…

Catching up

One of the things I ordered for this system was a battery cabinet to hold the batteries that has its own built in busbar system for connecting the batteries, and which is also lockable to keep people from fiddling with things they shouldn’t. That was on backorder and I got an email from Signature Solar telling me I could either wait, or they could ship me a slightly different model cabinet. Like everyone else they’re still having supply chain issues. I told them I’d take the different model and that should be here Monday. I jury rigged things together so I could test the inverters and charge the batteries but it can’t stay that way. Once the cabinet arrives I can get the batteries properly configured and start putting everything together.

I have more solar panels on order because my 800 watts of solar is woefully inadequate to keep 15 KWh of batteries charged. Those are supposed to be coming May 15 so I’ll need to build frames to hold all of those.

Gardening Stuff

The weather hasn’t been very good but we’ve managed to get some work done out in the gardens. Once things warm up and the skies clear up we’re going to be really busy. We’re taking out a crumbling stone wall and replacing that, moving two of the raised beds to a new location and a bunch of other stuff going out there. MrsGF has had her indoor greenhouse going down in the basement for weeks already starting plants that will get transplanted outdoors as soon as the weather permits.

Artsy/craftsy stuff

The brewery called me the other day, asking if I’d make more drinks coasters for them. A couple of good friends opened a brewpub, something they’d dreamed of doing for years. So they bought a building with an existing tavern that had enough room for them to put in their brewery and then… Then Covid hit. And somehow they still managed to pull it off and even managed to pay the bills during that whole mess. And now they’re doing pretty well.

Anyway a while back I found some super cheap plain drinks coasters made from wood and some from paperboard and for the heck of it I fired up Photoshop and made some graphics, putting their logo on one side and an allegedly humorous illustration on the other and then used the laser engraver to burn it into the coasters. i thought they looked a bit on the unprofessional side but they were fun to do so I did a few. I never thought they’d actually use them in the bar. But they did, and apparently the customers loved them. And stole them. Which was okay because it’s good PR for the brewery. So I’ve done dozens, maybe a couple of hundred of these things over the last couple of years and I just got a request for more so I got that going on. People are easily amused, I guess.

But enough of this. I need to get going here. I’ve probably put you to sleep already with all of this. I know I’ve nodded off a couple of times myself…

Artificial Intelligence, Art and Controversy

I don’t often talk about computer technology and software here because A) it’s generally pretty boring, and B) there are far better sources for information about this stuff than me. But I want to talk about “artificial intelligence”, or AI as it’s known, because it has some serious implications for all of us as it comes into more widespread use. While I used to be a programmer I’m not so much interested in the technology of AIs as I am in the ethical and social implications of AIs, and that’s what I want to talk about briefly.

Take a look at that painting up there. It isn’t bad, really. Personally I’d like it if it were a bit brighter, but overall it isn’t horrible. It’s sort of a generic winter scene, peaceful, pleasant even.

Or what about this one —

Both of these paintings are originals that I just did in the last few days, but I didn’t make them in the usual way by applying paint to a surface or even a using a stylus on a drawing pad as I usually do. These were done by an app on my cell phone that is available for free on Apple’s app store called Draw Things. And as you can see it is pretty damn good. Well, sometimes. I will admit that about 8 out of 10 of the images it generates are, frankly, a bit, well, surreal. Like this one below.

I found myself wondering what kind of drugs my iPhone was on to make it produce something like this.

But that being said, that it works at all is, I think, a bit amazing. What’s even more amazing is that unlike some of the other art AIs out there which actually run on some massive server somewhere out there on the internet, Draw Things runs entirely on the phone, no external processing power required. You can try it yourself although I’ll warn you that your phone will need a lot of free memory (the libraries the software uses are a gigabyte+ in size and you need at least one for the program to work) and using the program frequently will suck up a hell of a lot of battery as well because it really makes that processor work hard.

When you run the program, what you do is type in words and phrases that verbally describe the scene you want painted. Let’s say you type in something like “A white cat sitting on a table with vases of flowers” as an example. What you get is something like this –

MrsGF thinks that image is just creepy but personally I think it’s kind of charming, but everyone’s tastes are different.

But these art AIs have also generated a hell of a lot of controversy as well, and for good reasons.

Yes, this one was generated by that app running on my cell phone.

First of all, artists, actual real world artists who create real world art, are very nervous about all of this and for very good reasons. There are thousands of artists out there who earn their living as graphic artists, illustrators, etc. for advertising agencies, magazines and the like. Publishers and corporations don’t give a fig about things like ‘artistic integrity’ or keeping illustrators gainfully employed. They only care about money. So if it comes down to paying an illustrator money to create a piece of artwork for them, or generating something essentially for free with an AI, guess which option they’re going to take? They’re going to go with the AI everytime.

Another controversy is how these AIs are trained. Before these things will work properly they have to be trained by feeding them literally millions of illustrations. They do this by scraping the internet for every image they can get their hands on, whether those images are protected by copyright or not. Under a strict interpretation of copyright law some claim that this is an illegal use of those copyrighted images. Others claim that this use qualifies as what is known as “fair use” and is legally and ethically acceptable. I’m not a lawyer and I’m not even going to try to figure out whether how these things are trained is legal or ethical or not.

Then there is the question of who “owns” the artwork generated by an AI. That image over there on the right was generated by Draw Things. So who actually owns the rights to that image? You could argue that the image was generated by my phone, using an application that I own, so therefore the image is mine and I own all rights to it.

But it isn’t as simple as that. These days you don’t actually “own” the software you are using. You’re merely licensing it. Basically you’re renting it. That’s been the case for decades now. Under the licensing agreement you agree to, and which you almost certainly haven’t bothered to read because you’d have to hire an attorney to figure it out for you, the maker of the software can set any conditions they like, and it is claimed that your mere use of that software means that you agree to all of the conditions in the license, whether you read them or not. It would be entirely within the realm of possibility for the maker of the AI you’re using to claim any and all rights to any artwork generated by the program. Unless you carefully read the fine print in the license agreement, you have no idea what you are agreeing to.

Some people have started to claim that the AI that generated the image “owns” it. The people who are making this claim either need to find a new hobby or stop taking whatever drugs they’re on because this is just stupid. An AI isn’t an intelligence, it is a computer program. Period. It is no more ‘alive’ than the old Eliza programs people were playing with back in the early days of computing. They’re little more than a complex series of “IF-THEN-ELSE” choices pre-programmed into a computer. Oh, all right it’s a lot more complex than that, but what it boils down to is that an AI is just a computer program like the one I’m using to write this. It is no more “intelligent” or self aware than the calculator you use to figure out your taxes.

The other thing that makes people very nervous is the fact that these things can be used to generate images that mimic specific artists. Want to have your very own original Van Gogh to hang on the wall? You can. These things can easily mimic the artistic style of most well known artists, living or dead. Living artists claim that this reduces the demand for their original artwork. People who like their work don’t need to buy an original or, more likely, an authorized print of the original work, they can use an AI to generate their own in the style of that artist.

I would imagine that the companies that have become wealthy selling stock images for use in publications, companies like Getty, are terrified by this kind of technology because it would very easily put them out of business. Let’s say you’re writing an article about, oh, shopping malls, and you want to put in a photo of a nice looking mall. Instead of going to one of these stock photo companies and buying one, just make your own. Like the one over there on the left. It took Draw Things a little over a minute to generate that. My cost? Zero. So why would anyone ever need to buy generic photos for illustrating articles any more? So let’s just say that investing your pension fund in companies that sell stock images probably isn’t a good idea.

And these things can be used to produce some not so nice images as well. Pornography, s0-called ‘deep fakes’ that portray celebrities, politicians or other well known persons in, oh, compromising positions, let’s call it, can all be generated with nothing but a program like this and a few written descriptions of what you want to see.

Some of the developers of these programs are starting to put filters into the systems to try to prevent or at least limit their capabilities so they can’t be usfed for illicit purposes, but that is ultimately futile. The technology is now out there. A lot of it is open source, meaning anyone can tinker with the underlying code. And there are versions of these programs already out there in the wild, so to speak, tweaked to specifically crank out these types of illicit images. Let’s face it, my friends, that’s what human beings are like. As soon as human beings developed things like writing, painting and drawing, they started using it to make porn.

There are already people out there demanding that something need to be done. Right now. By someone. Somewhere. Congress needs to act now! Act how, though? Ban the software? Sorry, that horse is already out of the barn. Thousands of people are already using it and hundreds are tinkering with the code to make it work even better.

What it all boils down to is that we have a lot of questions, a lot of ethical concerns, a lot of legal issues, and no real answers.

Please feel free to leave comments about this. I’m curious about what other people think of all of this and if anyone has proposed solutions to the problems.

Crazy Gardens and Stuff

Well, it’s official. The gardens here have gone nuts. This is probably the best growing season we’ve had since we moved into this place twenty or so years ago. The ornamentals, the vegetales, fruit, everything is looking pretty much spectacular.

We put in a few raspberry plants a few years ago because MrsGF’s sister gave us some, or we wouldn’t have bothered because I can’t (or am not supposed to, anyway) eat raspberries because I have diverticulosis and seeds and nuts can cause it to flare up. They sit in a little 8ft by 8ft patch of the garden behind the garage and they never really did that well. Until this year. For about a week now I’ve been picking a bowl full almost every day. They’re starting to slow down now and will probably stop producing by the middle of next week. Beautiful berries. Just wish I could eat ’em. Sigh…

I wasn’t going to put squash in this year because we haven’t had very good luck with them. But MrsGF found a different variety and put in a few plants and they’re doing good too. So far no sign of powdery mildew which pretty much ruined them last year.

We cut back on the number of tomato plants we put in. Last year we put in 12 or 14 plants and even though it wasn’t a very good year for tomatoes we still had more than we could ever possibly use. We only put in six plants this year in the raised beds and, well, so far it looks like we’re going to get more off those six plants than we got off a dozen of them last year. They’re just barely starting to come ripe now and I’m looking forward to having fresh tomatoes again.

And dear lord, the beans… We put in two varieties this year, a wax bean and some pole beans and we over planted those as well, it seems. The picking season is only just getting started and we already are getting more beans than we know what to do with and are looking for ideas of dealing with ’em. We’ll probably be giving away a lot of produce this year.

We put in a few different varieties of peppers, and it looks like they’re going to be ridiculously prolific as well. I’m not really sure exactly what variety these are. They were labeled “hot pepper”, but no variety was listed. They aren’t really hot, though. They’re actually quite mild. There is a tiny bit of heat there, but they aren’t even close to jalapeno peppers. Nice flavor, though. I think I might try canning some of these as pickled peppers.

I’m a bit concerned about the pear tree. It’s so loaded with fruit that branches that normally are about head height are already being pulled down almost to the ground by the weight of the fruit. I think I’m going to have to start snipping fruit off the branches I can reach before we start having branches breaking off.

I call this the finch corner. The cone flowers and sunflowers are finch magnets, or will be in a week or two as the seeds start to develop more. In a fairly short time this whole corner will be swarming with finches coming for the seeds. Great fun to watch out of the windows of the house.

Let’s see, what else… Oh, I made a – a thing again!

Bottom part is cherry, top is… Well, to be honest I’m not sure what kind of wood the top is made from. It’s a piece of scrap I found down in the shop and thought it made a nice contrast with the bottom. You can see an indentation around the middle of the bottom part. That is going to be stained very dark, almost black, to add contrast.

What the heck is it? Who knows? It isn’t useful as a bowl or anything. It’s a sort of, oh, art piece? Maybe? Kinda?

How To Draw A Cat (Recycled from old Tumblr account)

how to draw cat.png

I thought I’d put this one up here at the same time I posted it on the old Tumblr account but I can’t seem to find it here. So here you go, how to draw your very own cat.

I have no idea what was going through my head when I drew this. Sometimes weird stuff just pops up in my brain.

New Photos And How Stupid Am I (Very)

Even though today is officially the start of spring it sure doesn’t feel that way. Temperature around 34 degrees, cloudy… We’re impatient to get outside and do something again.

Nevertheless, I had the camera out and was taking some photos of the indoor plants, some of which are flowering right now.

Screen Shot 2018-03-20 at 1.09.48 PM

This guy is sitting in the kitchen window at the moment. Those flowers are only about a quarter of an inch across. Here’s another shot of a different cluster of flowers on the same plant with different lighting…

Screen Shot 2018-03-20 at 1.10.42 PM

That camera does a great job taking closeups like that.

Another plant in flower at the moment is this one:

I love this plant. The color of the leaves, the texture, and those tiny little pink flowers that are about the size of the head of a pin. It’s a lot of fun.

MrsGF’s violets are in full bloom too right now:

Then there’s this really weird plant…

Screen Shot 2018-03-20 at 1.11.54 PM

That’s Kai. I’m very surprised she held still long enough for me to get that photo. She usually runs away when she sees me with a camera.


And now, on to the stupidity…

Nothing makes me look dumber than when something goes wrong with my radio equipment sometimes. This one was a real gem, though.

For some reason the TS-990 decided to stop transmitting AM and I couldn’t figure out why. Everything seemed to be working just fine otherwise. I could still use SSB, the digital modes, FM, all were working fine. But when I keyed the mic using AM, it would go into transmit mode, but no signal.

I spent something like two hours this morning trying to diagnose what the problem was. As a last resort I got out my morse code key and hooked that up. Not sure why. Just was trying to eliminate other things as problems. I tried sending my callsign in CW and…

And nothing. Same symptoms as the AM problem. It went into transmit, but no signal, no power going to the antenna.

Hmph… I went on line and searched around, found out there was an update for the radio’s firmware, so I downloaded that and installed. That went well. In fact, better than well because now the noise blanker works the way it’s supposed to and some other little things were fixed. But same problem as before, no AM and no CW.

I pulled out the manual once more and started to dig through that and…

Oh. Oh, brother… All right, look, the 990 is a very complicated piece of equipment. I mean it has controls and knobs and buttons on it that I’ve never used in the almost four years I’ve owned the thing. So I suppose I can be excused for not noticing this.

Most of the knobs on the radio are “nested”, that is there is a central knob that controls one function, and an outer ring around the central knob that controls an entirely different function.

The Power knob which controls the rig’s output power is the central knob. The outer ring is something labeled “Car” which stands for carrier. The carrier setting is essential to transmitting in CW and AM modes. I normally have it set dead center right in the middle. But since I almost never do CW or AM I almost never touch it. But I do use the Power knob to adjust the wattage going out to the antenna or feeding into the amplifier.

Somewhere along the way, the Car knob got a bit sticky and started to track along with the Power knob when it was turned. But only in one direction: down. When I turned the power down, it was also dragging the carrier knob down towards zero, but not dragging it back up when the power was turned back up. Eventually the carrier was turned down to nothing. So without a carrier, there was no AM or CW.

Sigh… Spent more than two hours trouble shooting a problem that didn’t really exist. All I had to do was turn the Car knob back up to the center position and all was well.

And now I just found out my amplifier relay isn’t working… How did I get into this hobby in the first place?

Along The Roadside

Screen Shot 2017-08-03 at 5.54.50 AM

It was a glorious morning Wednesday when I went out not long after dawn. One of those glorious mornings when the rising sun seemed to be making everything glow.

My attempts at using the panoramic mode of the iPhone7’s camera have never been very good. The mode works, yes, but the results never seem to be that good, to be honest. The image of that meadow up there just doesn’t look that good. So let’s look at these instead: click on one of the images to start the full size slide show.

These, on the other hand, turned out pretty good, I thought. I have to admit that the iPhone 7 camera works pretty well under some conditions.
