Just got a chance to throw a full wave rectifier and some caps onto the coils from before. This results in a nice 2v source at about 18mph. woot! startup transient seen above (yellow is cap voltage, 1v/div, 2s/div). The output voltage is proportional to the speed, so at about 25mph it hits 3 volts or so. this is OK. Ill add a protection
Zener anyway, but i think these are good levels. Ill add a
boost to this stage to get the voltage high enough, and then a
current regulator to charge the batteries.
