I've recently acquired a "high end" soldering station so I find myself enjoying soldering lately. That being said, soldering always needs good lighting. I almost always have my computer next to me when I'm working on something so I decided to make a simple little USB light that was easy to manipulate and put where it needs to be.
Step 1: Parts Needed
The parts list is simple and I had the materials lying around. You can probably get this from a Radio Shack for a few dollars or scavenge something broken.
-62ish OHM resistor***
-LED of your choice
-Old USB plug
-Twisted wire or hookup cable
-Relatively stiff wire (doesn't have to conduct electricity)
-Some tape (electrical is probably the best)
***Resistor may vary depending on your LED needs. Source voltage is about 5 volts from USB. I suggest this website if you don't want to second guess yourself: http://led.linear1.org/1led.wiz. I use it all the time because I doubt my math abilities.
