The RCA 151 Oscilloscope
This is probably the second oldest piece of equipment that I have in my collection, but this one is known working.
The RCA 151 Oscilloscope (or, oscillograph as it was known at the time) was one of RCA’s early test equipment products, and was supposedly one of the first scopes that was considered “affordable” enough for a small radio shop or well-off hobbyist to purchase. It’s not calibrated in any way, shape, or form, and doesn’t have the ability to lock on a trace - it’s just a purely visual indicator to see waveforms as they travel through a device. It has a top end of about 15Khz, and utilized a 1” RCA 913 tube for it’s display.
Of note here is the overall good condition of the device, both inside and out. I don’t think it was used much. Also of note is the input jacks - I believe these were biding posts at one time, but someone replaced them with banana jacks. Note the burn mark on the right where a hot lead hit the chassis instead of the jack!
The device (and others like it) were made in Canada. This one is unusual in that it was meant for the Niagara Falls power standard of 25Hz - a system that was available until 2006, when equipment failure wrote out it’s final chapter.
It works fine on 50 or 60hz, the 25hz functionality being provided by some extra filter capacitance. As far as I can tell, nothing else changed.
If you’d like to read about that power system, the IEEE published a whitepaper on it in 2008. You can retrieve it from their website by clicking this link or, in the event that they no longer offer it, by using this link that will download it from my document storage site. This is a PDF document.
The cord and grommet appear to be original, from pictures I’ve seen. The technician plug, however, is probably fairly modern - no earlier than the 60s.
So, let’s get some stuff out and try it! My trusty CSC generator has outlived pretty much anything else I’ve had, so we’ll set it up.
The display tube itself isn’t very bright. It’s just enough to see in a lit room, but works well enough. I don’t think this is age, I just don’t believe these were very bright to begin with.
It doesn’t lock because there’s no sync of any sort, so you have to mess with things to make it stable - and then it generally starts rolling again. As said, this was simply to show you the waveform.
What’s inside? It’s a relatively simple circuit consisting of a Type 80 rectifier, two 6C6 for amplifiers, and an 885 Thyratron for the sweep - essentially this is like SCR sweep in a late Sony CRT Television.
Everything is in really superb shape here - no rust and very little oxidation on anything. This thing must have been a prized piece that sat on a bench.
Note the capacitors - that big box capacitor in the middle has been spliced in and the joints coated with old-school cloth electrical tape. I would assume that RCA would have used their own brand parts at this time, and not Aerovox capacitors, but I’m not sure - but this most certainly was repaired at some point. The old dry Aerovox ‘lytics are still good, to this day, so whatever technician made that choice - I salute you, sir.
The bottom shows the parts of the era. Dogbone resistors and lots of capacitors here with minimal marking. It’s all on a terminal board, so completely rebuilding this would be easy, if it was necessary. I don’t ever plan on using this thing on a daily basis- so it’s not.
There’s more of those Aerovox capacitors. Maybe that was original? Did RCA just take an off-the-shelf unit and splice in an extra capacitor for the 25Hz model?
The entire thing has that “smell” of old electronics. You know what I mean.
Last - the paper label inside is still intact.
Time to put it back together and back on it’s display shelf.
There’s plenty of information out there on this device, including ads and manuals. A good source for that information is located at The Oscilloscope Museum, which displays it’s own example of the device. An advertisement for the device (also from the aformentioned site, check it out!)

My device cost $44.95 - that’s $1015 today!
Maybe not so cheap for a well-off hobbyist, but certainly invaluable to the radio shop…

The Westinghouse 54884B Watt-hour Meter Standard.
This is probably one of the oldest pieces of equipment in my collection that could sensibly be considered “electronics.” This is a watt-hour meter made by the Westinghouse Company of Pittsburgh, PA, and was designed to be used as a calibration standard for other measurement systems.
While the case itself has seen some better days, it’s still relatively intact for a device from 1919. A few cracks, and the hinges were missing when I got it. It has a lovely brass nameplate on the top:
I love the patent dates here. That’s 1895.
The actual range is selected by a big knob in the middle. There’s no clunk of detents, but the knob has two pointers. They’re lableled “1” and “2” - the knob turns all the way around so I assume that it’s a brush inside the device riding on something that connects a shunt for the current portion of the meter. Not sure at this point, however. I have to assume that the numbers are for the incoming voltage range - but again, not really sure.
The really cool thing about this device is the instructions and original calibration card are still in the lid:
And even more cool? There’s a calibration sheet with notes from 1930 and 1933 on it:
But the million dollar question here is does the thing still work? No idea right now. I need to open it up and make sure there’s nothing inside that’s broken first, and do a little study on the instruction card. For now, it’s just a neat display piece, but could potentially be put into service in a pinch - if the innards are still good!
Stay tuned for pictures from inside the device.

Yet another test box - The Waage Model 066.
This is a benchtop test box I picked up at the Breezeshooter’s Hamfest this past June. It’s simply a switched, fused outlet with some indicator lamps and a current meter. It proclaims itself to be a Waage Electric Model 066, “All Purpose Tester.” It’s in eh shape, and probably sat on someone’s bench for decades.
The cord is in good shape, which is surprising for the age, but both the neon pilot lamp and the little 7W peanut bulb for the circuit test are dead. It was probably “on” for most of it’s life. The neon bulb in the pilot doesn’t even do the flickering thing at this point.
Everything seems to be mechanically working, the switch snaps with a nice thunk, the meter pointer moves but needs to be adjusted, and all of the sockets are intact. Of note here is the Edison Fuse - no 3AG glass fuses here!
The inside is pretty clean, overall. I can immediately see the cord appears to have been replaced because of the way it’s put on the screw terminals - it’s unlikely the factory would have shipped it all birdcaged out like that. So that’s probably a new(er) cord.
Of real not here is the small gauge wire used for the device. The orange wire appears to be about 22GA solid - that’s not going to handle the 15A this thing is supposedly rated for. It makes me wonder if this thing was completely redone at some point in time, as there’s a mix of thermoplastic and cloth-coated wire in this. It’s of an age where everything would have been cloth coated.
In all, it’s kind of a neat piece, and was probably meant for testing products of the kind that Waage made - heating devices such as irons and coffee pots. For the $1 I paid for it, it’s literally a nothing lost proposition.
If I wanted to use it, the non-polarized outlet would need to be replaced, as would the cord and small gauge wire. I’d probably try and save the original pilot lamp, and find an incandescent bulb for the test socket.
But who knows. It’s of limited use other than a “That’s cool” thing to have on your bench. I’ll probably clean it up and see what I can do with it, stay tuned!

Remember Geocities?
If you don’t, geocities was an early “personal web space” host that allowed you to create a simple page. They ranged from fan sites to personal ramblings, with some information and everything else in-between. I collected a lot of useful things off those pages, including stuff like pre-made plugins for software, links to companies of interest, and images of otherwise unobtainable things.
These sites were more often than not characterized by garish backgrounds, flashy things, more fonts than you knew existed, sound and music blaring out of your speakers, and all of the Under Construction GIFs that your machine could possibly handle without melting your video card.
I used mine as a holder for links that I could hit with my BlackBerry, among other things.
But, in 2009, Yahoo! decided they wanted to discontinue the service - 10s of thousands of web pages, full of information from the old internet, would suddenly vanish - and it would have if not for the efforts of companies like geocities.ws, among others. There were many projects to collect as much of this data as possible. Personally, I think Yahoo! really did a big F*** YOU to the internet by not handing over the archives - or at least keeping it static. It’s not like their draconian TOS didn’t give them the right to do whatever they wanted with your data.
Regardless, I found my site in the .ws archives and claimed it by having them send email to the (at the time) existing yahoo address of the same name. It’s been a few things over the years, but right now it’s a quick-link to this place, with a few preview images.
While there’s nothing on that site you haven’t seen before if you’ve been browsing the wereboar pages, it’s still there just in case. Why not, it’s a small free space to host something. If you had a geocities webpage at some point, there’s a chance it in the geocities.ws archive. If you have some way of claiming it, like the yahoo address associated with it, you may as well do so. Time to relive the old internet, party like it’s 1999, and use at much comic sans as you can!
My current geocities page
The Projects From the Bottom Drawer preview page.
(no epilepsy inducing flashing images or synth-pop that blows your speakers out, I promise - and I won’t even open your CD tray.)
I wonder if I should put a hit counter on it?
If you’d like a copy of the entire archive as retrieved by ArchiveTeam as the place was shutting down, you can find it on that site by the bay…the one where the skull and crossbones fly. Search for “Geocities” and select the one that claims it’s patched - the other one has issues and won’t complete. The files are fairly well looked after, so you shouldn’t have any issues retrieving it. It’s almost 700GB, so make sure you have room for it, and the 1TB of uncompressed data.

Pictures from Coolspring Power Museum’s Spring Expo on the way.
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.
Stay tuned!

Minor imperfections. Priced to sell.
I picked one of these guys up at Dayton for $20, modified to work in the 2M band. Figured, hey! I’ll pick up some parts units.
For some reason, a non-working device with a (hopefully intact) broken display cover, swollen batteries (and quite possibly corroded inside,) no battery cover, no (oddball) power adapter, and covered with dirt for $250 doesn’t inspire me to add “Priced to sell” in the description. Especially when the device has been superseded many times over with modern equipment at lower prices.
At least it’s free shipping!

pygg.xyz, the former home for this blog, is nearing it’s end.
Hosting for pygg.xyz, as well as email and SSL services, have expired. I’ve set permanent redirects so that any pygg.xyz link should send you to the wereboar.com page of the same name if it exists, or the top level of Projects if you’ve not asked for anything special. There may be a couple of (very old) broken links, but those will take you to the blog’s 404 page with information on how to find what you want to see.
Those redirects may not always work, I’m investigating that but I don’t see any immediate resolution.
You can go to the top level of Projects to see the newest stuff, or you can go to the popular posts page to see everything on Projects from the Bottom Drawer.
I used to host this blog on pygg.xyz, but rapidly found out that .xyz domains have little trust in the Internet world. This affected both my ability to present things to you, and send email reliably using that domain.
Last year, I decided to see what was available - and for some reason, wereboar.com - a very old domain - was available. The former owners, a web design shop and later, some sort of graphics design shop, had let it go. I picked it up and moved everything here, because who doesn’t like lycanthropes? It’s been much easier to get email through secured systems with a .com domain, so here I stay.
My original domain, pygg.xyz, has been live all this time, but was a simple redirect to here. However, the end is nigh and the hosting for the domain ends on July 4th, 2024. The domain is still there and good for another 7 or so years, but the hosting will be gone.
Right now, there’s a parking page indicating that it’s 410, and to come here instead.
If you have any pygg.xyz bookmarks, now is the time to move them. Most should still work if you change pygg.xyz to wereboar.com, but if you can’t find what you need then check the popular posts or sitemap, available from the main blog page.
It will probably redirect here again, but I’m not sure what I want to do with it. It’s for sale, if you are interested, and it’s pretty cheap. Contact me with the LinkedIn links on the main wereboar landing page.
Until then, it will at least resolve to something. Where does the future lie? Who knows, but I’m sure it’s full of strange electronics and oddball projects.
I hope you’ll come along for the journey.

Breezeshooters 2024 - What I brought home.
I tried to limit myself to things I could possibly use, and I (mostly) did so. We’ll see if all these things actually work, or if some of them need some work.
This HP AC Transistor Voltmeter Model 403A seems to be in good condition, and has a Westinghouse tag on the back. I can’t really test it because it has some odd battery requirements. It looks to need 5 mercury cell batteries - 2 4V batteries, and 3 1.35V batteries in a configuration that provides bias and + / - voltages. These are unobtainable, so a small supply may be in order if I actually want to use this thing.
This came from a vendor that had boxes of parts. One part was $2, if you took the whole box it was $1. So…I took a box of mica capacitors and some other parts. High voltage mica caps can always come in handy.
This DigiMax Instruments D-1200 counter claims to go to 1.2GHz, and has lamps for an ovenized reference on it. It’s awfully light, but it does light up. I need to get a signal in it to see if it’s actually counting, or if it’s just spitting out garbage.
The Harris-Dracon butt sett was picked up becaue it was cool looking. I don’t know what I’ll use it for, but whatever. The Waage All-Purpose Tester Model 066 test box was a dollar - it’s mostly just an ammeter you can switch out, with a fuse and a lamp for testing the AC line. It’s pretty rusty, but looks clean inside. Who knows where this will end up.
This VIZ Senior VoltOhmist WV-98C meter seems to be operational, and has a case you could kill a poodle with. It’s a two-tube unit, using a 6AL5 Dual Diode and a 12AU7 amplifier. It’s small enough to go on the bench instead of the giant EICO VTVM currently there.
This Weller solder gun has all of the tools with it, and is one of the units made in the USA. I have a couple of these, they come in handy soldering chassis items.
That’s this year’s haul. I tried to limit myself to smaller items I could use, and I mostly succeeded. There were a lot of larger items that I wanted, but left there since I don’t have room for them. In all, I didn’t spend a lot and brought home some neat things.
Next show is either the Van Wert, OH show - that’s a long drive and may not be in the cards - and/or the Columbus, OH show which is a lot closer to me and much easier to attend. Either way, stay tuned for pictures from those shows, and I’ll see you there!

Pictures from Breezeshooters 2024 Hamfest.
It was raining where I was, and threatened rain all the way to the show - but when we arrived, the sky had cleared and it was a sunny, slightly breezey 71F. Essentially, perfect conditions for wandering the aisles. While I didn’t see some of the things I hoped would show up this year, there was still quite a bit to look at. I spent a couple hours wandering the show before heading out for some lunch.
The usual mix of equipment showed up here, and a few things managed to wander home with me. This is what I saw at this year’s show:
.
Next show will probably be the Columbus, OH hamfest, although there are some happening before that. Regardless, I’ll (maybe) see you there!

Don’t stay at toxic workplaces.
A recent LinkedIn post talked about a manager style the author calls the “Up your own butt” boss. You can read that post here: https://www.linkedin … edium=member_desktop. You may need to log in to see it.
A position I held several years ago had a direct manager that fit this bill. Everything good was “We,” everything bad was “you.” Blame would be shifted, even if he was at fault.
Shortly before I left, he stormed into a shared technician office and started berating us about someone charging time - in this case, weeks - to overhead. (Overhead at this company was a charge number that you could use when you were just doing general tasks that had no direct charge. Things like setting up new equipment, cleaning an area, etc.) He was going to find out who did this, they were going to be disciplined. Possibly even fired.
He knew very well it was him doing it. He was having a house built at the time, and would go spend hours on site harassing the builders.
He should have been fired for that, as this was weeks of time he did nothing and lied about it. There were other incidents that he should have been fired for, including destroying expensive equipment from negligence.
Unfortunately, it was endemic to the entire company. His manager - the chief engineer - had a severe god complex. He was incapable of looking at something and going “Good work men, you did a great job!” Instead, he would go “I’m a great man, look at what I did.”
I learned very quickly not to go to this man with ideas, he would discount them immediately, and then implement them under his own name.
It was a terribly toxic place and almost drove me to alcoholism. I’m not proud of that, but I got out with the help of a good friend. Bless you Lance, I’d be dead if it wasn’t for you.
