Killer marshmallow gun

Finally, a high powered PIC controlled marshmallow gun – “This device uses a PIC12F629 to create a burst of 30 high voltage pulses. The PIC activates a 1000 volt N-Chan FET driving a standard ignition coil. After the ignition, the PIC goes dormant until activated again. Most of the electronics, including the battery and momentary […]
