So you've got your paper throwing stars and homemade smoke bombs, but what's missing to really complete your ninja arsenal? LED Nunchuks, that's what! Jeremy Cook of JCOPRO made this pair with just a few pieces of PVC, some LED wheel lights, and sturdy wire to connect them.
As far as tools, all it takes is a drill, a vise, and a saw. The process is simple: just drill a few holes, insert the LEDs, and use the wire to tie them together.
Once you've made them, you can even use them for light painting!
