So here I have setup some rainbow LED's that have built in sequencers to create amazing wheels for RC cars. specifically for Drifters since their wheels are continuously spinning and don't really go fast allowing viewers and racers to see the full effect.
the video shows the wheels in motion but also is an actual tutorial in itself.
Step 1: Parts list
Batteries x 12 or 3 packs of 5 (LR41 cell size. Dollar store has tons.....)
Some small gauge wire (20 gauge will do)
a 30 watt soldering iron
Some Rosen core Solder
Some Chrome Wheels (find them at macphreak.com)
Slide Switch x 4 - Mouser.com (Model # 688-SSSS711403)
LED = Rainbow 3 mm x 8 (Not that easy to find, try ebay)
Fine grain sandpaper (400 grit will do)
A Pair of Helping hands
Cyanoacrylate (CA ) glue (Hobby grade, PLEASE USE CAREFULLY.)
Step 2: Cleaning off the chrome
Take one disc and clean off the chrome off of both side. the reason for this is that chrome is conductive and your circuit would get shorted out and be useless.
I took a spare axle shaft, installed the disc on it and then put the shaft on my drill. Spin the drill and use the sandpaper to take off the chrome. Take a few seconds per disc.
Step 3: Marking for battery placement
Now at each line measure 2mm from the edge and drill a hole (probably about 1/16th) the size of the wire you used.
Put aside for later use
