There's one inductor there too. The reason I noticed is I just pulled about ten out of a board. After years of not building anything I've recently got back into the hobby. I'm currently facinated with diode ring mixers, toroids and other inductors. I recently purchased an L/C meter that arrived a few days ago. The LC-100 that you did a video on. It was your video that clinched my decision to buy that one. I wanted something low cost but able to measure low inductance. Mine didn't have instructions and I only just worked out how to calibrate it for measuring inductors. You join the two leads together, hold the red reset button. You then get an okay. I suppose it needs to take into account the inductance of those leads. I was wondering why I was getting readings too high for low inductors. Bigger ones too I suppose, but not so noticeably. I went from being a bit disappointed with it, to being very very happy with the purchase.
It is out of a cheap computer UPS. It quit working after about 18 months, but the components are surprisingly good quality. Must have been a design flaw that killed it.
This video is fine, but it’s intended for people who already know quite a bit about electronics. Somebody should buy a Radio Shack 200 in 1 project board, and go through the lessons, one by one. If a young man knows just a few things, he can make his own projects. All he needs is a breadboard, and a basic understanding of transistors and relays.
Radio Shack has been gone for a while now. I used to build their projects, then I graduated to HeathKits. HeathKit is also gone. Nowadays you have to find a project on the internet, buy your own parts, and learn from that. Sometimes the projects are well laid out and explained, sometimes not. These circuit boards are a good source of cheap and hard to find parts.

Hey,
Interesting build, looks like a prototype board. I’m curious about where this was mounted? Thanks for the video.

Thank you, I have learned from your videos
Glad to hear that!
