Well.. here's an instructable on it, but there is an extra: you can actinate it by a remote RF
control. It is so powerful, i can light up my hole room!
Step 1: What You Need
*any all- purpose transistors
*high power leds preferabely 5v
*a working remote control toy-car (not in the picture)
Step 2: The Circuit
Step 3: Disassembling the Car
the 2 power wires and the 2 wires going to the motor.
Step 4: Solder, Solder
firs of all, solder all the led's in parallel. Then the potentiometer and everything else.
Step 5: Finished
Make some shadow from the sun and see it lithing.
Hope you liked my first instructable.
See the video of it working.
