I've been saving up a few links. I don't keep as many around as I used to, I've been only saving ones that really make an impression or will be fun to post. Here's my latest collection.
Candle-Powered Candle
I saw this, then I went home and pulled out a few heat sinks, a fan, and a candle. It didn't work for me. I don't have the exact parts he used, though, just something close. It makes sense that this could work: the candle heats the heat sink, the heat from the heat sink will rise, moving the air, and that will cause the fan to rotate. The rotating fan will generate electricity (like a windmill) and power the LED light.
Ginheads Rejoice
Tired of spending your hard-earned money on gin? I know I am! Putting this on your Christmas list will save you some money and you’ll end up with the gin you’ve always wanted – the homemade kind. Hawkeye and Trapper will have nothing on you.
Speaker Project - Two Will Get You Stereo
Definitely do-able. Maybe M's next project...
Gravity-Powered Light
What a great idea - a light that's powered by gravity. It appears to work on a similar principle to a grandfather clock, although more high-tech.
Instructables
If you haven't seen Instructables, it's the place to find your next project. Here's the electronics section, but there are others. Look around!
