King Flavor Tester

[nawt40]

Made this out of a Forward/Reverse control for a toy car. Right now both buttons operate it at 3.7v. If I turn over one battery and put them in series, one button runs at 3.7v, the other at 7.3v. I need to find resistor to knock it down to a reasonable voltage. Kind of cool for testing flavors at 2 different voltages.

Nice. Perfect size for a pair of 14500's + stuff.

According to Ralph these RS diodes knock off .8V. Two in series would bring you down to about 5.6V.

Thank you. That will do it...Just checked, and I have room for them. Off to the Shack. Need some switches for these mods anyway.
