Variable Speed Air Pump/Compressor Built Out Of An Engine
Built a variable air & vacuum pump/compressor out of an old weed wacker engine, some check valves & tubing. Driving the cylinder using a 12V motor. Pulls 240W on full power, which equates to about 0.32 horsepower. The controller I built for the motor is based on an arduino pro mini. Used the compressor to blow up a latex glove in this video. It popped at the end and scared me half to death
