I agree: a regulator is the only sensible option. Use a special
low-drop 3 volt regulator (intended for use in computers) and you will
do fine.
I didn't build my device in a winder yet. I think the best place for
the regulator is inside winder (in place of the cogwheels, which have
to be removed). One or two capacitors can be built in there as well.
The 'probe' on top of the winder, to enter the battery chamber, had
better be solid instead of holllow with an even smaller regulator
inside. Don't forget: housing of winder must be connected to positive
3 volt, probe connector to negative 3 volt.
BTW, if you dimension the probe snesily, it will fit into the battery
chambers of OM 2,3 and 4. Do not try connecting to an OM-1!!!!!
