Probably a boring video. Just playing with it by varying voltage. Don't even have a voltmeter set up.

The LED behind the blower is connected in series with the blower, to serve as a simple current sensor. Also there is a 200k resistor in series, to make sparks less loud and annoying. Though, this causes arcs instead of sparks. This may cause damage by melting plastic, but so far so good.

The blower is quite noiseless. You should be able to notice clock ticking if you set the volume high.
