IR Controlled Brush

I made a vibration engine by DC motors of remote control car that are sold in $1 shop. And finished as a "running scrubbing brush" by sticking to the scrubbing brush.

Past the screw to the shaft of the motor with the glue bond, and rotate it, the scrubbing brush runs in the vibration.

It is controlled by very simple circuits for generic IR remote controller like a TV, and any micro processor or programming is not needed.
