    Question on calculating resistance needed

    I have a 24v 250ma wall adapter and a 12v 250ma fan, I'm trying to calculate the resistor needed to put in so I don't burn the fan out. I came up with 48ohm resister using ohms law 12/0.25. It seems low to me, am I missing something? I realize I'm going to lose some current through the...

    After doing some searching I found a project that might be interesting. Using an old pc cooling fan to build a mini extractor. I have a couple of old pc's lying around, and I just found a 13.5v battery charger for something that doesn't work any more. Should I get a 12v adapter, or is it...

    I thought desoldering parts off of old scrap electronics would make for some good practice. Having something where switches would light up led's as some sort of puzzle sounds like it would be fun to make. As for a workbench power supply, what would you recommend. What I was thinking of making...

    As for parts, I have some old cell phones (I'd really like to learn how to repurpose one of the old lcd screens), some old computers, a couple of old vcr's, and some other random stuff. I have some programming experience, all self taught. I've done a couple of simple games. I also have a good...

    Projects for Newbies

    Hi everyone, I've been interested in electronics for a while and finally decided to start fooling around with it as a hobby. I was wondering if anyone had some beginner projects they could recommend to start really learning how to do stuff. Also any ideas for projects that involve salvaging some...
