If you’ve been reading this thing for any length of time you know I love gardening and flowers. It might be mid October and we’ve had some pretty cold weather, but some of the plantings around here are still going strong like the flowers above. I still can’t believe how big those flowers get. My hand is in the photo so you can get an idea of how big they get. We still have two flower beds with these guys in full flower.
The alyssum have been hanging on too. Beautiful little flowers that are incredibly fragrant. I can usually smell them as soon as I go out the back door of the garage where they’re planted.
And these guys up there can be depended on to keep going strong well into late fall until it starts getting really cold.
Cleaning up the yard this fall has been a lot easier now that the pear tree is gone. Having that tree collapse was kind of a blessing in disguise. We miss not having the pears, but we definitely do not miss the mess the tree made. Trying to clean up all the falling pears was an incredible pain in the neck, and we’re going to have a lot fewer leaves to deal with this year too.
MrsGF and I were discussing what to do back in that area now that the tree is gone. We’re going to have a much larger area with full sun there now so that’s going to expand the planting possibilities enormously. There was a small heart shaped garden there that we put in back in 2000 that was almost entirely shaded out by the tree. Next spring we’re going to be expanding that to the west into an oval shape that will include the tree stump, about 20 feet long and 6-8 feet wide. That new bed will probably be for ornamentals.
We thought about making it a raised bed but discarded that idea. That area is very well drained to begin with so we don’t have to worry about too much water as we do at the back of the house. We’re going to have to haul a ton of compost in though because the soil there is pretty poor. Not going to do anything with that until spring, though. We’re still sketching out ideas about the exact size and shape of the bed and what we’re going to plant in it.
And I’m still fiddling around with wood. I finished this thing last week.
That’s a vase, not a bowl, and one of the bigger things I’ve done. It’s about 10 inches tall and 6 inches wide, made from walnut and oak. It turned out reasonably well. I really like working with walnut. It machines beautifully and I love the color and grain. A glass insert goes inside so it could be used for fresh flowers, or leave out the insert and put in dried or silk flowers.
That vase started out looking like that monstrosity over there on the right. That was a block of glued up old bits of walnut and oak I found laying on the shelf that I didn’t have any plans for. And to be honest I had no actual idea of what it was going to be when I started this. Usually when I start something like this I have at least a general idea of what I want it to be, but not in this case. I really don’t recommend people just sort of “wing it”, but in this case it worked out in the end.
That was biggest thing I’ve ever tried to spin up on the lathe. It was so wide it just barely cleared the bed of the lathe. Usually I try to round square blocks off by knocking off the corners with a saw to make it balance better, but I don’t have a saw big enough to handle a 10 inch tall, 8 inch square block, so I just had to spin it up slow, keep my fingers crossed, and start chipping way at it.
That’s it for now. Hopefully next time I’ll be continuing the tool series and talk about thickness planers and jointers. Unless something else comes up first.
(Where the grouchy farmer rambles on and on and on about misc. stuff because he’s bored.)
What Is the Future of Ethanol?
Someone asked me about the long term future of the ethanol fuel industry, and I think I rather shocked him when my reply was that it has no future. None. Within ten to twenty years the entire ethanol fuel industry will be dead if current trends continue.
The entire transportation sector is on the cusp of a major change as consumers become increasingly interested in electric vehicles instead of gasoline and diesel cars and light trucks. The current generation of EVs are extremely good for the most part. They now have significantly expanded ranges, often on the order of 200+ miles before needing to be recharged. They’re good looking, comfortable, nice to drive, and are far less expensive to operate than gas/diesel vehicles, and require little maintenance. The biggest problem right now seems to be the lack of fast charging infrastructure, and that is a problem that can be rather easily solved.
So if current trends continue, the era of gasoline/diesel fueled transportation is nearing the end. And that means people using ever decreasing amounts of gasoline and diesel fuel. And that is going to cause huge problems in the farming business because almost 6 billion bushels of corn goes to make ethanol. That’s not a typo. In 2018, the last year I had accurate data for, almost 5.8 billion bushels of corn, more than 40% of all corn grown in the US, went to making ethanol. And in a fairly short time, that market is going to come to an end.
You’d think that the ag industry would be concerned about this. But the ag industry doesn’t seem care. As far as I’ve been able to see, the ag industry is doing absolutely nothing to prepare for the day when literally half of their corn market is simply going to disappear. And that kind of scares me. Apparently they seem to think they can keep bribing lobbying Congress to keep propping up the whole market through increasing blending requirements and other government intervention in the markets. What they should be doing is looking to the future and examining alternative crops to take the place of corn. Not even the government is going to be able to bail them out of this situation.
I’m having way too much fun with that new lathe. I’m new to using this thing so I’m still in the experimental stage, learning how to use the tools properly, how to prep the wood, etc. I’ve managed to crank out a few items that are actually pretty good looking, but that’s due more to the woods I used for the project than my skills as a wood turner. It’s hard to really screw up a lathe project when you start out with wood as nice as in that bowl up there in that picture.
The biggest problem is getting my hands on cheap wood to play with. So far I’ve been using up scraps left over from other woodworking projects, but I have actually spent real money on some premium hunks of wood. Really good wood, with excellent grain patterns and good color for serious projects gets expensive pretty fast. I’ve seen some hunks of “artistic” woods going not for tens of dollars or even hundreds of dollars, but thousands of dollars. But then again I’ve seen people glue up bits and pieces of old shipping pallets they got for free and turn out some pretty respectable looking stuff.
This bowl is a work in progress, made from ambrosia maple, and yeah, that little hunk of wood up there was expensive. I think it cost about $25 for a 6 inch square, 3 inch thick piece of that stuff. And I was surprised to get it that cheap. The stuff seemed really too good to be true when I read the ad, but, well, heck, I thought I’d give it a try and ordered four pieces of the stuff and, well, holy cow it’s nice. Incredible colors and grain patterns. It’s absolutely spectacular.
I’m still in the learning and experimenting phase of all of this. Not every attempt at turning something has turned out good. Some have been complete failures. In one case I was turning piece of oak and it literally exploded. If I hadn’t been wearing safety gear I’d have probably ended up in the emergency room with face injuries. Learning how to properly use the tools takes considerable practice. You can watch all of the training videos you like, read all the books, etc. but nothing except actual practice will get you to the point where you can do this with some skill.
Sometimes things turn out pretty good, though. Like this one.
This one turned out a lot better than it had any right to. I still need to make a lid for this one. MrsGF is telling me I should be trying to sell some of this stuff. Yeah, I don’t know about that. If I start trying to sell it then this turns from a hobby into a job. And sell it how? Etsy? Ha! There’s so much competition from similar products on Etsy I don’t see how anyone would even find my stuff. Just look up wooden bowls over there and you’ll see what I mean. And prices are brutally low, with decent wooden bowls selling for less than $30. Sometimes a lot less.
There is something not quite right going on there. I suspect a lot of those “hand made” bowls are mass produced junk being bought up wholesale by the vendors. You can’t turn hand turn a bowl, sand it, finish it, pay for the raw materials, equipment costs, supplies, plus your time, and then dump it for $20 – $30 and still make a profit on it. Add in Etsy’s fees… Sure, there are “art pieces” going for hundreds of bucks, but how many of those actually sell? Few if any, I’d suspect. Considering the amount of time I have in that bowl up there, plus the cost of the wood, wear and tear on the equipment, supplies, etc. I’d have to get probably around $150 to break even on that bowl up there.
Speaking of wood, our pear tree is literally collapsing under the weight of the fruit. It just went completely nuts developing fruit this year. It’s almost impossible to get a decent photo of the damage because most of it is up at the top of the tree. Looks like at least three major branches have completely collapsed, snapping off or cracking because they couldn’t support the weight of the fruit. I knew the tree was overloaded but I didn’t think it would get this bad. It’s going to be difficult to see just how bad it is until the leaves start to fall. We’ve actually been thinking of taking that tree down. It’s leaning at a crazy angle that seems to get worse every year and it shades out areas where we’d like to grow other things. And while having fresh pears in the autumn is great, a few pears go a long way and probably 95% of the pears end up in the compost. Well, we’ll see.
The gardens are going through one last burst of color before autumn comes. But some things are already starting to die back.
The hostas are starting to look pretty nasty up in front of the house. One thing with hostas is that once a leaf is damaged by bugs or anything else, it never grows back, so the accumulated damage from an entire summer of bugs, rain, etc. is pretty apparent. Still they do amazingly well for most of the summer. Once the frost hits in the fall they’ll die back and we’ll just leave them until spring. The old foliage can then be raked up easily.
The tomatoes are starting to die back as well. They’re still producing but they aren’t going to be around for more than another couple of weeks. They did really well this year. We cut way back on the number of tomato plants we put in, and even so we still had more than we really needed. And we’ve learned to use a calcium supplement to fix the problems we’ve had in the past with blossom end rot.
This is where we had the pattypan squash. While the plants did well, the squash themselves were a disappointment as far as eating is concerned. I’ve never had a squash before that literally had no flavor at all. No flavor, no aroma, nothing. I don’t think we’re going to grow those again. We don’t have a lot of space here to begin with, so growing something with no flavor doesn’t make much sense.
For the last few years we’ve been growing full sized sunflowers right outside of the south window of the living room. Not only do we get to see huge, brilliant yellow flowers right out the window, we get the added bonus of seeing flocks of goldfinches come swarming in to eat the seeds this time of year. They’re little acrobats, hopping and clinging upside down to the plants to get at the seeds.
And they’re chattering away at each other all the while. I think a couple of them got into an argument about politics the other day judging from how loud they were yelling at each other.
The Delta 46-460 mid sized lathe arrived ahead of schedule, and so far it’s a beauty. Now I don’t have a lot of experience with lathes, but to me going from the piece of junk I had to this is like going from a Model-T to a Porsche 911. Holy cow it’s nice! Beautifully machined, everything fits flawlessly, bearings are perfect, heavy, nicely machined cast iron and steel. It was even boxed beautifully. It was double boxed, with a heavy duty cardboard box on the outside, a 2nd even heavier duty box inside of that with foam spacers to protect the inner box, then about 6 inches of dense styrofoam inside of that encasing the whole thing. Set up took no time at all. Just wiped it down to get rid of the excess oil, checked everything over, put the banjo in place and it was ready to go. It is a pretty hefty beast, though. Shipping weight is about 120 pounds, but all that weight helps to damp down vibration.
I had to try it right away of course, so I put in a scrap piece of wood and fired it up, and oh, my… Smooth as silk. Motor has lots of torque. It’s fantastic.
It has three belt positions to make big speed changes, but also has electronic variable motor speed so I’ll rarely have to change the belt position. It is very, very nice.
Anyway I’ll talk more about this thing in the future as I get a chance to use it for an actual project. Now I have to start scrounging around for wood!
I could go crazy with the camera just taking photos of all the flowers in the gardens this time of year. I haven’t processed any of these yet, these are the unedited images.
And people wonder why I love gardening so much…
Well, that’s what I call ’em. These things:
I call them zombie lilies because this is what they look like when they first emerge from the ground.
They are the most bizarre looking things I’ve ever seen. There’s absolutely no indication that there is anything growing there at all, and then these weird asparagus like looking stalks suddenly pop up and a few days later they put out these beautiful flowers.
What they actually are is amaryllis belladonna. They’re sometimes called naked lady lilies because they just have the bare stalks with no leaves. They’re native to South Africa but are widely grown as ornamentals.
We have no idea where they came from. We certainly never planted them. They popped up a few years ago, but we hadn’t seen them since then, and this year we now have three large clumps of them. They really shouldn’t be growing here because they don’t like Wisconsin’s cold winters, but there they are.
I should also point out that every part of the plant is poisonous, especially the bulbs, and they are very dangerous for dogs and cats. So I’m not sure I really want them out in the garden at all to be honest.
I have a ton of stuff going on around here, but none of it is important enough to make a single post so I’m just going to shovel everything into this one [grin].
Cheap crappy lathe
I’m working on another lathe project, this one a bit larger than the last two, and that cheap Harbor Freight lathe is showing the strain rather badly. I got this as a gift so I shouldn’t complain… Oh, hell, sure I should complain. This thing is just plain nasty.
Harbor Freight has a reputation for selling cheap, cheap tools of questionable quality. My experience with HF tools has not been good, and this lathe certainly hasn’t improved my opinion of their stuff. While it worked fairly well for tiny stuff, putting a substantial chunk of wood on it has brought out all of its faults. I already knew it was made from cheap, thin, stamped sheet metal, including the base. In a real lathe, the bases are made from heavy, cast and carefully machined cast iron or steel. So this thing flexes and vibrates and shakes and rattles. The bearing are worse than awful. The motor is woefully underpowered. According to the label on the motor it’s rated at 1 HP. I’d be willing to bet it’s not even a quarter of that.
So I have to decide now if I like woodturning enough, and will do it enough, to justify dropping about $500 – $700 on a good lathe. I still haven’t made up my mind.
MrsGF tried something new this year, pattypan squash. We really like squash, but we haven’t had much luck growing it here. Last year our acorn squash was overcome by powdery mildew, and other years we had other issues. So she thought to try this. And it seems to be working beautifully. The plants are ridiculously healthy and absolutely loaded with fruit. We’ve never eaten this variety before so we’re looking forward to trying it. We have about three now that are ready to eat so this week we’re going to try them.
Biking as Meditation?
Everyone thought I was nuts when I dropped about $600 on a bicycle after I retired, figuring it was something I’d do for a couple of days and then it would end up hanging in the garage and getting in the way. Instead, several years and about three sets of tires and three thousand miles later, I’m still at it. And I have to admit that even I am a bit surprised at how much I enjoy it. But I’ve always been a bit of an outdoors person. I spent most of my childhood at the farm down in the woods, watching tadpoles in the streams, sitting in the woods watching chipmunks gathering acorns, watching frogs, listening to birds and trying to spot them in the trees… It was a journey of learning, amazement, wonder, and beauty. Well, except for the mosquitos. And somewhere along the way I lost that, only to have rediscovered it now. I get out on the country roads around here, especially down on the trail, and I can start to lose track of time.
And birds everywhere! Especially down along the river by the old stone bridge on Irish Road. Herons, ducks, egrets, even pelicans come down to the river. Yesterday I was watching a belted kingfisher perched on a telephone line running across the river, eyeing the water, and every once in a while diving down to try to snatch a small fish. I can hear the cardinals calling in the trees, but rarely see that flash of red. I see more of those in town where the trees are more sparse and it’s easier to catch sight of them.
And the smells… I am blessed with (or cursed with, sometimes) a hypersensitive sense of smell. As I’m out riding I can smell everything – the chicory and clover along the side of the road, the corn, the alfalfa fields, people mowing their lawns or cutting hay, a whiff of tractor exhaust wafting across a field from a distant farm, the fuel the RC airplane guys use in their planes as I get close to their flying field off Hwy 57, the wood preservative on the wooden bridge over the river on the trail, the occasional dead animal in the ditch, the asphalt outgassing on a hot day. And more often than not, an undercurrent of manure from some farm emptying its storage pits miles away.
I took up biking originally for the exercise. I went from a job where I was on my feet all day, walking for miles a day, to essentially nothing, almost literally overnight. So I figured I needed to do something or I was going to blow up like a balloon. And while the exercise is important, yes, the other benefits of being outside, the sights and smells and sounds and all that goes along with it, probably does more to keep me healthy than putting on 10 miles or so a day.
It’s been a spectacular year for growing stuff this season. Weather has been just about perfect so far. We’ve had an unusually high amount of rain so we’ve only rarely had to resort to dragging out the hose and watering cans. We’ve been blanching and freezing wax and pole beans about three times a week for a couple of weeks now. We’re rather sick of it, to be honest. MrsGF came up with a bean salad recipe that is absolutely fantastic, so she’s been using up the beans, along with some of the peppers and onions we’re also growing, and canning that. Holy cow that stuff is good.
The tomatoes are just starting to come in. Not enough to process into a batch of sauce or soup, so I’ve been dicing them up and throwing them in the freezer. Just wash ’em, core ’em, slice or dice them, throw them in freezer bags, and then pull them out whenever we need tomatoes for something.
Pretty soon though we’re going to be deluged with tomatoes, so we need to decide what we’re going to do with those.
And flowers. The whole yard is alive with flowers this time of year.
Anyway, that’s about it for now. Stay safe out there.
If this time of year could be described by a single word, it would probably be “color”.
Almost everything is in full flower this time of year except for the autumn flowering plants. Just walking outside is a feast for the eyes.
So, let’s get caught up on what’s been going on. I haven’t talked about it much but one of the things I do is build furniture like, well, like this:
It looks a bit beat up now, especially the upholstery, but considering it’s lived through two teenaged boys, a rambunctious golden retriever and several assorted cats, it’s doing pretty good. Over the years I’ve built chairs, coffee tables, wardrobes, bookcases, decorative chests and I don’t know what all else. A few years ago one of my sons gave me a cheap wood lathe from Harbor Freight and I finally started fiddling around with it. It was super cheap and to be honest the build quality isn’t exactly what I’d call good. But I’ve messed around with it a bit, bought a decent set of tools for it and I’m going to see if I can add woodturning to my skill set. We’ll see how that goes. I’ll let you know if anything comes of it.
We’ve been spending a lot of time out in the gardens, of course. Where else would we be this time of year and with the pandemic still raging? Gardening is probably the safest and most satisfying activity we can do right now. But we’re still dabbling in radio. And I mean “we”. MrsGF is a licensed amateur radio operator as well. She’s more into the emergency services aspect of it while I’m more into the technical stuff.
It looks like the Great Radio Fiasco Project is back on the agenda. I was finally able to get the toroids I needed to wind the coils I need. But considering how busy we are with other things this time of year it’s likely that will be pushed back until the fall.
Let’s see, what else… Oh, I’m working on an upcoming post that answers some questions about amateur radio that people have asked. That will be coming up in the near future.
I’ve been working on getting better at CW (morse code). I’m still struggling, especially with receiving. I’m nowhere near good enough to be able to actually use it out in the field. If someone sends at like, oh, one word per minute or slower, I can generally figure it out. But any faster than that and everything sort of blurs together and I start to fall so far behind I have to give up.
Someone asked me if I was going to do anything for the ARRL Field Day exercise. Nope. Don’t have the time. This is probably the worst time of year for me to try to participate in an event like that.
We’re going to be doing some major renovations to the house this summer, replacing a bunch of windows, the front entrance and some other stuff. That’s going to be a mess, but it needs to get done. And expensive. Sigh… Oh, well. Owning a house is great. Until you start seeing the bills for maintaining it.
These little guys are amazing critters. They’re tiny little things. That cable you see there is less than a half inch thick so you can see just how small he/she is. Frogs are some of the most amazing and, I think beautiful creatures around. I’m still astonished that we have these little tree frogs around here.
Speaking of trees, the pear tree looks like it’s getting a good start.
It is absolutely loaded with baby pears. That ought to make up for last year when we got maybe a dozen pears total off the whole tree.
The ornamental gardens are looking great here. The recent rains and warm weather has everything growing like crazy right now. Most of these plants have tripled in size in the last week or so. You can almost see them getting bigger. Oh, and the bird houses are occupied again this year. Looks like some type of wren?
We restrained ourselves and didn’t crowd things into the two raised beds this year. Just 6 tomato plants and the outer edges with onions. Even six is probably too many because we probably still have six months worth of canned tomatoes of various types on the shelf. But the lure of fresh tomatoes is something we just can’t ignore. And we can always give ’em away if we have too may.
This is garden faces south and west and is the most productive spot we have. Sheltered from the wind, with light concentrated here, it gets warm early and stays warm late into the fall. Have to be careful what’s planted here because the warm, sunny conditions means a lot of stuff like lettuce and radishes will bolt. Also it has to be watered a lot. But we usually get ridiculously amounts of produce out of this corner. The tripods in the back are for pole beans. There are various baby pepper plants protected with #10 cans, and more beans and parsley seeded down in front.
Time for a musical interlude. You may want to turn your volume up. Or maybe not?
People sometimes ask me what I’ve been doing since we can’t really travel or do much except putter in the garden. I’ve been playing amateur radio, of course, and trying to get better at CW. That’s morse code for you non radio people out there.
Doing CW is something I never really thought I’d get into. I’ve always been far more interested in the digital modes like PSK and JS8Call. But I also love QRP, using extremely small amounts of power to try to communicate, and what works best for QRP is CW. And unlike the digital modes, CW doesn’t require you to lug a computer along. So I’ve been spending about a half hour or more a day trying to learn and get better at this. I’m up to, oh, maybe two words a minute?
Then there’s this thing.
I’ve been looking at solar power and batteries to power my QRP gear and even my full power radios for some time but never got around to actually getting involved with solar because A) I’m lazy, B) I wasn’t sure I’d ever actually use it, and C) the stuff can get a bit expensive. But then this deal came along…
I have to admit I have very little experience with solar power. I never even heard of this company before this deal came along. But the stuff seems to get decent reviews and the price, well, I picked up the 20 Ah LiPo battery pack, with a built in 120V inverter (sort of), USB and 12V power outlets, built in high intensity LED lights, LCD display and other goodies, and a folding 40W solar panel for less than, well, let’s just say that I’ve dropped more money on a meal at a nice restaurant than I spent on this deal.
Anyway, I’ll be taking a closer look at this in the near future to see if it’s a real deal or not. I’ve only just taken a quick look at it, but right now it looks pretty good. Especially that folding solar panel. That thing looks like it’s very high quality. Well, we’ll see.
If you’re like me, you’re ready to scream because of the 24/7 fear, panic and everything else you’re seeing on the news and internet. So here’s some photos to distract you. Well, if my internet connection stays up, that is. It’s been down a half dozen times already today.
That’s enough for now. I’m pushing my luck with my internet connection here, I think. It went down three times while I was uploading photos.
They’re claiming another major storm will roll through here starting to night. We have flood warnings, winter storm warnings, ice warnings, heavy snow… Well, considering they totally blew their last storm warning, we remain skeptical. Last Sunday we were supposed to have 8 or more inches of snow, high winds and blizzard like conditions and we got bright sun and mild winds. So we’ll see. But this time of year I always find myself paging through photos from warmer weather because I’m getting very impatient for spring to get here. So here goes. I’ve probably put some of these up before, but what the heck…
Apparently Mother Nature wasn’t satisfied with deluging us with snow a month early, now she’s trying to freeze us with temperatures we usually don’t see until well into January. It’s about 3 degrees (F) out there, with windchills down in the -10 range. Sheesh…
Meanwhile, MrsGF has this growing in the living room. Just took these photos the other day-
Yeah, roses. I’ve put up photos of this before, but I figured this plant would go dormant or something by now. But it just keeps right on blooming.
This thing started out as one of those goofy little teacup roses, a tiny plant in a cheap cup that they sell for a few bucks on Mother’s Day or Valentine’s Day. Think I paid all of $7 for it, oh, must be at least two or three years ago. And after we got sick of it sitting around the house MrsGF said what the heck, let’s put it in a big pot and see what happens and the dopey thing just kept growing and flowering. We were putting it in the basement, letting it go dormant over winter, but this year she thought she’d put it in the living room where it could get some light and keep watering it, and well, it apparently likes it there, and it’s been flowering on a regular basis all winter so far.
I asked her how she’s keeping it flowering and she swears she’s just watering it and isn’t doing anything else. Personally I figure witchcraft is involved.
The MagLoop Antenna
I talked about this antenna before, and I continue to be more than pleased with it. Since my dipole came down in the last snowstorm it’s been the main antenna for my TS-990, sitting on the floor behind me in the office. And it is doing ridiculously good.
The Great Radio Fiasco Project
I mentioned this before, but let me summarize what I’m trying to do here. For reasons I won’t get into right now, I challenged myself to build, from scratch, a decent radio receiver, preferably shortwave. Emphasis on the word “decent” because I could throw together a few parts and end up with – well, with something that would receive, well, something that might be a radio signal, and pump it into a speaker and you’d hear some sound that might be interpreted as a radio transmission by someone with bad hearing. It could technically be called a radio receiver, but, well, let’s face it, it wouldn’t exactly be useful.
When I first conceived of this project I was like how hard can this be? In those WWII movies the Resistance throws together a radio out of bits of string, a piece of wire, an old cigar box and bits off a horse (don’t ask me what bits, I don’t know, ask them, they built the thing) and call up Churchill at Bomber Command and call in an air strike on Hitler’s outhouse. And the Good Ole Boys in amateur radio weep bitter tears of disappointment over the fact that modern day hams don’t build stuff any more like they did, when they’d throw together a 1,500 watt amplifier, transmitter and superhet receiver in an afternoon, out of parts they salvaged from old washing machines. And bits off a horse for all I know.
Here’s the thing, though – 95% of that (maybe even 98%) is pure BS. I’m sorry, but it just is.
The days of being able to salvage anything useful from discarded electronics are long gone. Modern SMD (surface mount devices) and robotic assembly methods make it virtually impossible to salvage anything useful from relatively modern equipment. And while you can buy discrete components like resistors, capacitors, etc. in the more common values, increasingly it is difficult to find a lot of stuff in anything but SMD form, and in quantities of 1,000 or more. I was trying to find what had once been a very common opamp the other day. It is still available. But if I want to get it from a US supplier I can only buy it in quantities of 1,000 or more, and in SMD format. If I want it in the traditional 6 pin IC form, and only want a few of them, it looks like I’m going to have to order it from China and it won’t get here until mid-March.
Nor are parts cheap. Oh, some are, true, but not the kind of stuff I’m looking for. A single variable capacitor I need for a project sells for $25. And I need two of them. So I’m going to have $50 stuck in that project before I even get started on it.
And then there’s the design of the equipment you want to build. If you were going to set out to build your own radio receiver, probably the first thing you’d do is fire up Google and look for something like “build your own radio” and find, well, hundreds and hundreds of hits that are utterly worthless, along with a few sites that might have actual plans to build something. Only most of those plans are for useless crystal radios and other nonsense. And the designs that do look useful are probably going to be wrong and no one is going to tell you how to fix it when you build it and it doesn’t work. In fact, most of the designs I saw out there were copies of stuff pulled out of old radio or electronics magazines from the 1960s or 70s that didn’t work in the first place.
(Sidenote: I’m convinced that the building plans in all those electronics magazines published in the 50s, 60s, 70s, etc. were never actually built by anyone because about six or eight months after the plans were published there’d be a “corrections” item pointing out that they forgot this part, or the wiring was wrong and if you’d actually build the thing it would have exploded, electrocuted your cat or something.)
So the question is, can I build a decent radio receiver from scratch? Probably. Will it work? Maybe. Can I do it for less than what it would cost to just go buy one? No way in hell. Will it work as good as even a cheap piece of junk commercial radio? Almost certainly not.
So why am I doing this? Uh, because I’m a stubborn old goat?
