I love this sort of stuff -- does anyone know of a solid forum/place for these kinds of projects (outside of searching here)? Specifically, I have a basement full of old (some non-working) hardware for various gadgets/computers/electronics and I'd love to upcycle them into ... something else. Instructables and WikiHow are the usual places, but it's usually things that require "the thing you're building"[0] to build or require buying so many new components that by the time your done you've bought a product minus a few motors. I yearn for the "Make X do Y" with a small number of inexpensive tools (preferably ones I own, but that's a tricky proposition) where "X" is something common, or obsolete and "Y" is something outside of or is an upgrade to it's design[1]. I love doing this sort of thing and I find that about half the time when I'm working on Pi/Arduino projects I have way more parts than I realize -- I can't believe I purchased any loose low power LEDs (IR, colored...) I have a whole box of remotes/miscellania that should really be in the garbage for how useless it is ... until I need a 1.5V LED, have only 5V+, and can't wait a day for shipping. I started salvaging electronics before trashing them. It'd be nice if I could look up the whole obsolete device and see what I can use more of it in... plus, at least for me, I'd throw less away (and store less in boxes). [0] My go-to is the small number of "Blu-Ray Engraver/Laser Cutters". Every one I could find (A) required a laser cutter, or (B) many of the laser-cut parts required a laser cutter that was bigger than the one being built, so you couldn't even sell the more expensive laser cutter if you wish to be able to produce a second one. It's a small issue in that there are still other parts that need to be purchased, but you have to buy a laser cutter to make the custom, $0.01 in pressed board, set of parts. The others are nearly every upcycled RC-Car. [1] I had a friend who designed custom sub-woofers for cars when I was younger. He had a Yamaha off-the-shelf sub that he modified to the tune of $250 and some of his own time. It put my $1000 sub to shame. I can't remember all the specifics of the modification, but I know he used the original amp board and some upgraded MOSFETS but didn't touch the 10" speaker or the cabinet (which was what he spent most of his time on, typically).
