Saturday threatened rain all morning, and that seemed to keep the crowds down this year - the roads were relatively clear on the way home. In contrast, last year was backed up for miles in every direction with people trying to get in.
We arrived fairly early, and some of the vendors hadn’t opened yet, but we wandered the aisles, had some Bourbon Chicken and Fried stuff, and managed to see it all. Most was just flea market stuff, but there was some cool things on site.
This Admiral console radio was in pretty good shape for it’s age.
For your 1812 Overture re-enactments.
An adorable miniature bulldozer. It’s low, maybe this was for use in a mine? (No, these were sold to the general consumer as a small piece of equipment. There were other attachments for it as well.)
A nice looking Edison Home unit with crane and witch hat horn. Did not pull the top off to look at it.
A clear Aladdin Beehive, and a pink and clear Aladdin Corinthian lamp. They were priced appropriately.
A Ford Model T. Price: 29k
A Sears Silvertone Trans-Oceanic clone. It was in ok shape, didn’t see the inside.
A nice Silvertone console radio. The eye tube was inside, but was laying on the chassis.
Standard of Ohio vanished in 1984 when purchased by BP.
A couple of old phones. The spotlight in the box beside them went home with me.
A real spinning wheel.
I suspect this was from a mine, but it was amusing regardless. (It’s from an oilfield, from what I’ve seen.)
It looked like it was going to rain about 11AM, so we finished up and headed home.
While not necessarily a hamfest, the Johnstown (Ohio) Swapper’s Day is a large flea market that usually has some electrical and electronics goods show up, with a healthy dose of everything else you’d expect from a flea market. Plenty of food on site, and you’re easily able to spend the whole day browsing the aisles. It’s worth a go if you’re looking for something to do on the Labor Day weekend, but be advised that you should get there early, as in when it opens - traffic backs up something fierce on those back roads.
Free parking is abundant, but is in a field.

The Coolspring Power Museum is a large display ground consisting of member-maintained static displays consisting of everything from small oilfield engines to a giant across-the-state natural gas compressor engine, with everything in-between. Much of it’s up and running for the show, with other stuff in various states of rebuild or runs during a demonstration time. It’s a fascinating place, and they have engines and displays that you’re literally not going to see anywhere else - at least not in this condition!
All of the images here are of those static displays. There are other items that pull in for display during the show, but that’s primarily through the week. Saturday is the last day of the show, so most of that was gone by the time we arrived. Still…there’s so much to look at, and we’ll probably head back for the fall show this year as well. This one is well worth the time to visit if you have interest in old engines.
As with the MVSTA show, I don’t have much to say about these pictures - so here they are, in all of their greasy glory.
While this, and other engine shows I attend aren’t necessarily electrical in nature, they are certainly prime examples of old technology. I’ve always found the mechanics of such devices to be fascinating, and worth my attention.
The MVSTA show is one that happens on the Western edge of Columbus every year, and I try to make it out there at least every few years. This year’s show was bright and sunny with no threat of rain anywhere. Prime viewing time for all of the mechanical eye candy that showed up.
I don’t have much to say about these pictures, so no annotations.
This year’s show was maybe 2/3 the size of normal - I suspect the dangerous looking skies kept some people away, but fortunately the rain held off for the show. It was, however, sticky enough that you could probably have put a straw in the air and drank some.
There were still some interesting things to be found at this year’s show, and some good deals to be had. This is what I saw this year:
A Cushman broadcast band analyzer and a counter among the parts.
A board from an early Atari arcade cabinet.
A “Bedframe” antenna. Well built.
One of those early programmable scanners at the bottom of a pile. Used punchcards.
I believe this is the club's table.
An HP 3300 Distortion Analyzer and some sort of teaching breadboard.
What you expect to see at these shows.
A silent key's artifacts.
You could bean someone with that switch.
Just stuff.
More of what you expect at these shows.
An Edmont sound level meter with Coshocton, OH markings.
Some equipment that went home with me, all lonesome.
The decade box I brought home, should have grabbed the vibrator tester too.
I brought home some things that I didn’t need, but isn’t that the point of this kind of show?
A Vishay decade box and a frequency counter / generator. They both seem to work well enough for the age. There’s also some high-voltage mica capacitors sitting on top of the decade box. Those were a buck, and I said why not?
I can’t go to a show without bringing home at least one meter. Unfortunately, this one seems to have some issues, it will zero but not read. I need to open it up and make sure that any batteries left in it aren’t corrodeedoodled all over the place. It had a lot of bad resistors in the divider chain.
This PACO generator is the same as one I have in better condition. This one is a $5 parts unit.
This is a PACO power supply that came from the same vendor as the generator, also $5. It’s an interesting piece, being an early bench supply for audio work, but in reality it’s a glorified battery charger. Stay tuned for a teardown on this guy. It eventually got passed on to someone for scrap. That’s what it’s worth!
No idea what this is, my fellow show-goer suggested it was some sort of early electronic switch for process industry. He’s probably right, but I got it simply for the cheapness of a 250VAC transformer that could be reused. I tore it down for parts.
That’s it for this year. I’ll be posting show pictures, and some other, recent engine shows as soon as I can get the images cleaned up.
One of my fellow show-goers was talking about taking some of the audio gear he collected to Dayton in 2025, and we’ll set up a table on the flea market. This sounds like a cool idea to me, I’ve attended shows but never had a sales table.
In the spirit of things, I took a look at what I’ve collected over the years that’s never going to go anywhere, and there’s a bunch. It’s time to start cleaning out, and I have a bunch of things that could go. Where does it all come from?
See you there, and maybe you can take something home! It’s cheap cheap cheap!
(If you see something you like, drop me a line on LinkedIn and we’ll see about a deal!)
Pictures from the Columbus Hamfest, Cool Spring Power Museum, and Miami Valley Steam Thresher Association shows are all in the works. There’s simply a lot of them and I have been a lazy little pig. Check back in the next few weeks and I promise that you’ll have some cool stuff to browse!
They’ve all been posted! Sorry it took so long on some of those…
I took a lot of pictures at the show this year. The individual exhibitors had mostly pulled out by the time I arrived, but the museum’s displays were all up and running in their greasy glory. I haven’t had time to fully process the images for display here, but they’re on the way.
