Introduction: Resistor Ring
"I Can't Resist Lovin' You"
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.)
~Sandpaper or Dremel with sanding bit

Step 1: Do the Resis-twist!
Once you have everything, you want to get the general measurement for the ring. Twist the ends together as shown in the picture. Once that's done, measured, fitted, and all that jazz, heat up your soldering iron and get to work. Flux up the corners and move onto step 2....>>>>
Step 2: Soldering
Hold the resistor ring together with some alligator clips when soldering. Make sure to follow soldering guidelines, seen here in the "How to Solder" group. After it is secure, clip off the extra wire, moving onto step 3 -->>
Step 3: Adding the LED Gems & Finish!
Well, this doesn't look very pretty right now, so, let's add some flair. Add the bigger LED first, twisting the wire around the ring. Flux it up, solder, snip the wires, and repeat for the smaller ones.
After that, whip out your sandpapering device of choice and make everything nice and smooth. Voila! You're very own, DIY, resistor ring!
