Hi, this is Archer 72, and I'd like to thank HPR for providing the servers to record to. This is going to be a little bit all over a place, but HPR was asking for shows, and they had a little bit of things to say, so I wanted to talk a little bit about my interest in electronics. Started when I was 10, I found a train set in the basement, and decided to set it up. It was just a little old track, and I had a really basic transformer, and I didn't do much with it after that. I played with a couple of little engines, and oh yeah, and I forgot the very first time I got any taste of electricity, so to speak, was when, according to my instructor, I felt a sine wave at three years old when I couldn't keep my little hands out of the power outlets. And thankfully in the US, where the house voltage is 110 volts and about 220, I managed to survive. A few years later, I get a bigger power supply of transformer, and more complex layout, which I make foldable out of the way at the ping pong table, which also folded down, so that we could have some family time. I didn't have a way to simulate this train, fully starting and taking time to stop, so I added a decent sized capacitor at the track output. I think it was about a thousand microfarads. That was also when I learned a solder, because the rail connectors would have intermittent contact. I'd also have, to use a heasing clip in order not to melt the track, plastic track ties. I also made up custom levers that went through the plywood to activate tracks, which is with solenoids. I remember correctly, there were catalogues for MCM electronics and all electronics, which I'll include in the show notes. And at this point, I think MCM electronics became another company like Newark. That's where I found the parts for this and other projects. I still have a bunch of atrial scale cars and engines in my parents' house. When I was building this layout, I learned how to use a hot resistance wire, my dad, and we cut Styrofoam as a base for some of the scenery. Also, I did a lot of bit of wire framing to do some of the inclines. And for realism, I was in a crushing of coal with a hammer to make realistic size pieces for the co-oppers. I should have actually used a mask, because I breathed in a lot of dust in that process. I dumped my midteens. I was still on the trains, but I took more to building circuits from any engineer project books. They had a radio shack. And there's archive.org, like the guy I could put in the show notes too. My favorite project at the time was a mini-stun gun that I made using a pre-built inverter from the catalogs that I had mentioned. And I put it, provided a hundred volts from the inverter circuit. And I ran into a, I think it was called deck stacked a bluer circuit. The result was a 1,200 volts at a few micro-amps, as far as I can measure. And in a couple of moves, I managed to lose it. I wish I had it around. I continued my interest when I was building an electronics one. I was building speed carrying closures for a sound system in my 1986 Chevy celebrity station wagon, which was my first car. I ran a high-amperage cable across one fair-eyed capacitor to account for the amplifier's current draw. And I built a custom board to hold those amplifiers that fit in the rumble seat of the wagon. In 1985, I was about the same time I was working with the car amps. And I had my first long-time job in the printed circuit board industry. I walked on the mechanical assembly for a year. And I myself and the SMT department are asking around and SMT is surface mass soldering. And I asked to learn how to do the SMT soldering and repair. This lasted about five years until I moved on to a medical device from manufacturer Baxter, which is spelled Baxter Healthcare. Here are the robust infusion pumps for about six years. These pumps would be set for a flow rate for vinyl fluids, of course electronically, through a keybed. You know, detect air pockets if the tube was pinched off or if the patient laid on it in the bed. I had a variety of jobs after that, mostly in contracting and manufacturing for PCB boardhouses. The last job before this was working on machines that analyze trace amounts of nitrogen to packaging environment. All right. Now they make floats where most of them make use or actually all of them make use of a sensor package for temperature pressure and salinity. It depths of 2,000 meters to study environmental issues. They have room for other packages if they have to do custom jobs for other clients. And up is a result in not the same thing, just one of them was to study hurricanes.
