	Gee, I feel like an advertisement for these things, but the 1N4007, though
cheap, is a little slow for the 200uS-ish pulse from the coil. I
experimented with this a year ago and they are inefficient, get hot and die
fast when used with anything but a 60Hz sine wave due to a very slow reverse
recovery time. Better to use then UF4007 (A string of 50 for your
application). More expensive but will work as expected for higher frequency
stuff like ignition coil rectifiers and DC Tesla coil "De-Q-ing" diodes. Get
these from Mouser or similar. Digikey does not carry them.
