Pictures from the 2024 Johnstown Swappers Day
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.

The 2024 Johnstown (Ohio) Swappers Day Flea Market
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.
Where:
Johnstown Community Sportsmen’s Club
7357 Sportsman Club Rd NW
Johnstown, OH 43031
When:
August 31 - September 2
7AM - 6PM
How much:
$10 admission per person
See you there!

It’s interesting how old data just keeps kicking around.
How many of you remember the 2021 LinkedIn data breach?
While not really a “breach” in the traditional sense of the word, it did result in some party scraping the public data of many, many profiles - the one I had at the time included. I’ve since deleted that profile for this one, and quit using the associated email address. I don’t want to give up that email address because it’s fairly desirable and attached to some other services I can’t migrate, so I keep it around.
I check that address every so often, because I know some people that I might like to talk to - and have not for a long long time - may still have it. Much to my amusement, offshore recruiters still email it, talking about how they just found my profile on a job board I don’t use and would I like this 2 month contract job in California for $22 an hour?
However, today was a little different. I’ve received emails from a few people contacting me at that address about how they just found my profile on LinkedIn, and because I was a successful business owner, would I like to consider franchise opportunities? I received one of these today, after a long dry spell without one.
They, of course, didn’t find my profile on LinkedIn using that email address, because it hasn’t existed since 2021. That tells me that the data from the 2021 breach (and possibly the 2016/2012 breach) is still out there, and being sold as fresh, useful data.
I politely emailed this guy and said that I was sorry but he bought bad, stale data, and asked him to remove me from his list since there wasn’t a business at that address, never was, and I was not interested in starting one.
I’ve had marginal success doing this. One guy seemed really confused until I found out where he got the data, and I told him why he had that data. One got very angry with me - that’s not the way to sell yourself. Most never reply. I never hear from any of them again, so I assume they get the message - but if not, it’s on them.
I hope this guy takes the hint. If he asks for more information, I’m happy to share.
What’s the moral of the story? All those “leads” that people are trying to sell you may not be what they seem. Pay attention to what you’re buying, you may be buying the last guy’s garbage packed up all neat in a gift box!

The NRI (Conar 200) “Appliance Tester”
I’m not sure what fascinates me about these little test boxes - maybe it’s the attempt by the manufacturer to put as many functions into a small a space as they can. Regardless, this little test box is one of those devices. Yes, it’s a device that could be replaced by a simple digital multimeter and a couple of cables, but this was supposed to be an all-in-one device with all of the necessary connections to do the job at hand.
This device is a tester from NRI, or National Radio Institute - a former school by mail organization. This device was probably included, unassembled, as part of one of the courses. It’s state gave you a chance to learn assembly and soldering, as well as some circuit basics. It was later marketed on it’s own as the Conar 200, Conar being the consumer imprint of NRI where you could purchase NRI devices without the need for the coursework.
This device came from the 2024 Cuyahoga Falls Hamfest, and was $3. I didn’t really buy it for the test box itself, but more the real copper clips and probes that were in the storage compartment. The device itself was interesting enough (but smells horribly of basement!) that I decided to check it out a little.
At first glance, it appears to be a multimeter - and it is. It features a battery powered two-scale ohmmeter, a two-scale voltmeter, and a single scale ammeter. The volts and amps functions are simple metered measurements without any kind of filtering or scaling save that necessary to make it a high or low range. It has pin jacks for probing the device under test, and a socket so you can do direct amp measurements. That’s all.
It’s a very simple, unisolated device. The cordset is live when the probes are, and vice-versa.
The back of the device is fairly simple as well. A few resistors, a potentiometer, the meter connections, fuse, and some sockets are all you’ll find, along with the battery for the ohms function (removed in this image.) The wire is of fairly small gauge for 20A, so this isn’t something you’d want to run for a long period of time. It’s really about as simple as you can get, and is a pretty good meter for just having around and not worrying about batteries (for the most part.)
The battery in the device is a little odd, the kit required that you solder it in. There’s no battery holder save the spring clip. You’re absolutely right in thinking that you’re not supposed to solder on batteries, and that’s for multiple reasons. The two biggest reasons is the electrodes aren’t really meant to handle heat like that, and in newer batteries the electrolyte is wet(ter.) Heat could potentially cause it to burst or burn.
The battery in this one had leaked over the years, but fortunately for me it was a carbon cell. The electrolyte caused oxidation on the battery surface, but there’s no alkaline corrosion mess all over the place.
I’ll probably stick a battery in it at some point and see if it works. I can’t believe it doesn’t, there’s nothing there to not work!

Has it really been 30 years?
It’s been a while, hasn’t it, old friend? I didn’t think you worked anymore, but it looks like you’re still sitting there patiently waiting for input. Your power connector is loose, so we need to see about that, but I’ll see if I can find your manual and make some magic.

The PACO B-10 Battery Eliminator and Charger
I picked this guy up at the Columbus Hamfest for $5. It claims to be a power supply of sorts, and a battery charger. It is lopsidedly heavy. So at minimum, there’s a nice big transformer in the thing, if all else fails.
It’s fairly unassuming from the outside. The front has the business end of the device - two meters, output terminals, output adjust, and a couple of switches.
As a note, this thing is only 6 and 12 volt, with a little wiggle room.
The back and sides are just as unassuming, nothing except some vents, the cord, and a serial number.
You’d think there’s some sort of regulation in this device, right? Wrong.
There’s pretty much nothing inside of this guy. Apparently, the only regulation is YOU, and that’s by turning the dial on the front of the device!
Inside, it’s a history lesson in electronics.
Lots of cloth-coated solid wire and big wads of copper and metal make up this device.
Here’s the power transformer, two giant sized but comparatively small value capacitors, and a giant choke in the middle that hides the voltage adjust tap.
Here’s some boom cans, aka old capacitors. These claim to have been made by Pyramid in 1958. 6000uF at 20V - these can be replaced by 6800@25 for about $4 each, and two of them would fit handily in the space taken by one, with room to spare!
No, I’m not going to try and charge them!
Last, we have the business end of the device. The rectifiers - in this case, giant selenium plates. I wonder what kind of condition these things are in. Are rotten eggs in my future?
This is certainly a product of it’s time - it’s interesting in that it’s a battery charger not made by one of the companies that did such things at the time, but also tries to be a primitive DC supply for device bench testing. Now, of course, we’d just grab a 20A switcher, but this thing was what you had in the 50s.
Is it going to go back in service? Not until I can at least get some new capacitors, but even then - it may just end up as nice power supply transformer in a box. Who knows where this is going…

These giant selenium rectifier plates
I recently picked up an ancient PACO B-10 “Power Supply / Battery Charger” from the Columbus Hamfest. I wasn’t sure what was in the thing, but turns out there’s not much.
These giant selenium plates, however, are a thing of ancient beauty. The whole thing looks like it’s era, a mash of wire, transformers, and rust. Stay tuned for a more complete teardown and other photos of this device.

I’ve added a mastodon feed to the blog.
I’ve had commenting here off for some time, mostly due to the spam problem. Flatpress is a great system, but all comment platforms, unless heavily moderated, are spam magnets.
However, I wanted a way to communicate with people that may be reading this blog. I’ve had my LinkedIn profile connected for some time, but that’s not an accessible platform for most. Mastodon, however, is.
Mastodon is one of the twitter-likes that came out of the old Gnu Social era. It’s exactly what you think it is, a feed full of short posts by multiple people, and you can follow and interact with anyone that’s a part of the “fediverse,” a loose-linked conglomeration of various servers and people.
That’s not to say Mastodon doesn’t have it’s own issues, the originator of the system has some hangups that prevented conversations linked to other servers because he didn’t like the content, and it certainly has a very political leaning if you dive into the main feed. That’s not what I’m here for - I simply want to post my weird electronics and give people a way to go “Where did you get that thing?”
If you’d like, check it out: https://mastodon.social/@wereboar - not everything here has been mirrored there, but going forward - it will be.
Thanks for hanging out with this little pig, and I’ll see you at the hamfest!

Pretty good for just pulling it out of a junk bin.
Here’s the decade box I pulled out of a box of parts and junk at the recent Columbus Hamfest.
Granted, my old Keithley Meter hasn’t been calibrated in many years, but … 2 Ohms? I’ll take it!

The 2024 Coolspring Power Museum Show
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.
