Anybody know of a big book of electrical circuits, or a forum consisting of guys who build circuits for fun? It seems like I'm always needing to figure out how to solder resistors and transistors and dio...isters together in order to do something, but it's a rare day when I can figure it out on my own.
Like how to adapt my 40-130 ohm fuel level indicator in my Ramcharger tank to read accurately on my 60-160 ohm fuel level gauge on my dash. I'm sure there's a simple little way to do it with a circuit, but I ought as well be building a nuclear reactor...
