Continuity Light?
Sweet, thanks for the ideas guys... I do have another question now... If I were to go with battery power, would it be more efficient to use a voltage regulator or resistors? Also, in this other situation I have where I'm trying to create a custom battery... I know that the output voltage is probably (I'll check it once I get the tools) 3.7V for the stock battery. It MUST remain that for this application. Anyways, my battery is going to end up being about 11.1V or so. Would I get longer battery life from using a resistor to regulate the voltage, or using a small regulator?
