For the blower motor (robbed from a defect hair dryer) a simple logic level N-FET (IRL540N) has been used. The chassis is from a cheap RC car illumninated with red, white and blue LEDs. As power supply 3 AA cells for the drive motors are used. A 9V battery block has been used for the blower motor and the 5V regulated controller supply
