I have always loved lights in motion because the visual effects are awesome, LED's have made this project possible and fairly easy to make.
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.
1/10 scale RC Car Disc Brake kit
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.)
