Re: [APML] Canon AE1

[George Anderson <georgea@CAM.ORG>]

I'd do more than just use resistors to drop the voltage. All it would
take would be an increase in current draw from the camera to cause you
voltage drop to increase, thus causing your current to increase, thus
causing the voltage to increase more... I think you get the picture.
For just a few dollars you can get a three terminal voltage regulator,
and if that isn't your speed consider using a small external battery
pack driven with "D" cells. The few bucks you save just using the
resistors to drop the voltage won't be worth the risk of trashing your
camera's electronics when you fire the shutter.
My two cents worth from 25+ years in electronics as an occupation and
photography as a hobby.
