“This is an Instructable on making a ring out of four (4) resistors and three (3) LEDs. This simple project is the perfect thing for your geek girlfriend with Valentine’s Day coming up.
Things needed for this project:
- Four (4) resistors (I used 220k-ohm 1/2 watt, 5% ones because of their red and gold stripes.)
- Three (3) LEDs, 1 normal sized one, two smalls. (Dead or working, it doesn’t matter.)
- Soldering Iron
- Sandpaper or Dremel with sanding bit”
