I does know about Super glue and Baking soda "plastic" trick, but never use it until now. Works like charm! I made aluminum foil borders...

    My version of Friction Bike.

    After some years of thinking, finally I made my version of Friction Bike. Idea comes from here: In my version there is the same principal, but I made it with local parts from Home Depot, eBay and local electronic shop. Two 555 timers, 1 relay, two Voltage stabilizers, 2 switches, 4S 8.8A...
