This Instructable will show you how to tap into a FREE source of electricity! All you need is a phone line! All phone lines have a constant flow of voltage, around 40-70 volts (up to 100 volts when it rings!), but you can't just plug stuff into it and expect it to work. You can really mess with your phone system by doing that. I discovered how to do it the right way!

Step 1: What You Need...

1. Small project enclosure
2. (1) 240ohm resistor
3. (1) 510ohm resistor
4. (1) LM317L Regulator
5. (1) KBP210 Bridge Rectifier
6. (2) Phone line cables
