Brain fart - "convert" 6VDC to ~ 3.7VDC
It charges with a 6VDC (500mA) charger. The battery puts out ~ 3.7VDC to the LED array. I don't know how much power/current the LED array uses itself.
My thought was to get a small DPDT toggle switch to install - it would "steer" the power from the DC transformer (120V plug in) to either the charging circuit (e.g. normal operation) OR to the LED array.
Yeah yeah I took circuits in HS and college but brain fart.... what resistors and whatnot do I need to wire in to get the 6V down to ~ 3.7V? Planning on stopping by RS tomorrow to grab the switch and could get the other parts too.
