More AA battery salvage
My AA battery/joule thief lantern is working fine, now I'm trying a regular flashlight. No joule thief this time, the bulb is incandescent, and I'm really cramped for space. I do have a series/parallel setup, hope to accomplish that with a simple wire swap.
My problem is the AA battery receptacle is putting out over five volts from each receptacle. I'm afraid I'll blow the 3 volt bulb. Is there anything I can do to protect the bulb that doesn't draw too much from the batteries? Will this remedy keep the bulb bright as the batteries run down? When the batteries drop to a low voltage, I plan to switch to series.
