This must be the lingering effects of all those Lew McCoy articles I read. I see a TV, I want to gut it and build ham gear. As I kid I would explore the neighborhood on my bicycle on the days the trash went out looking for junk TV sets. I had a set of tools in my pockets to pull out the chassis and would lug them home to gut. A friend of mine who lived in a house instead of an apartment would save the chassis whole in the basement (which bugged the gas man who had to climb over a mountain of tv chassis to read the gas meter!). I'm not a kid, but I still carry tools around. And I think there's a much better selection and quality of electronic junk being tossed than when I was a kid. Back then, over thirty years ago, you'd be lucky to find tv sets and AC/DC radios. And the heat from the tubes tended to collect all kinds of junk from the air (or maybe it was mainly because people tended to keep such things in use for so long) so they were terribly messy. And of course, the components tended to be big and bulky, though of course since it was in the late tube-era that's the sort of thing needed for building anyway. I was out somewhere yesterday, and came across a monitor that had a bunch of BNC connectors on it. If I hadn't been trying to get somewhere on time, I would have taken the time to get them off. As it was, there was no easy way to get that assembly off, so I left them there. I did pull two boards off, one digital, to strip down later. Having the tools is great. You can be selective. When you start out, most of such equipment can be useful, but as the decades drag on, it's too much trouble to bring the whole thing home. With tools you can get the equipment open and extract useful parts right on the spot. So you can pull the variable capacitors off any radio you see. Or pop open that computer to pull out any memory. I've been grabbing switching supplies from computers, partly because they are easy to extract, and originally because I thought I'd reuse them as power supplies. But there are more than enough for that, so I've started pulling the boards out of the boxes when I get home, and using the boxes for other things. Michael VE2BVW |
