Lightrider DIY Bike Light

Made a DIY version of the revolights http://www.revolights.com

total cost for one wheel is about 35 dollar

instead of a microcontroller i use simple reed magnet switches

the two outer rings consist of 18 Led's in 6 groups each all is powered by two AA batteries they are located on the hub

the only thing i don't have because i use the reed switches is the cool animation like revolights when the wheel stands still

Materials:

36x High Power 8mm Led's (18 on each side)
2x two meter long Aluminum stripes 15mm wide (in my case shortened to 1,75 meter)
6x Reed magnet Switch
2x 2meter 7 pin flat ribbon cable (one for each side)
2x 7 pin mini plugs (for easy installation)
Zip ties to mount the whole thing on the wheel

Soldering iron
Hot glue gun
Drill
