PWM Controller simulation

Simulation of a Pulse Width Modulation controller, found at http://web.archive.org/web/20070524202524/http://www.cpemma.co.uk/pwm_erg.html
Uses the circuit simulator at http://www.falstad.com/circuit/
Due to the nature of the applet, the schematic and graphs, but not the rest of the UI, is visible to Fraps.

I use that circuit along with a thermistor to control my PC's case fans.
