TARGET ! ;D That is the only place, other than online that I have ever seen them. In Target, you have to go to the housewares area like near the lightbulbs and such, as they have lights in the sporting-goods area, but none of the min-Dorcy's
Also, I have a question about a circuit. If I have 2 or 3 normal 1.5v batts and I wire then directly to a battery with a cap and some resistors of predetermined value, would it be safe?
Also, can I use any size cap? or does it have to be a certain volt rated for such low power. Like I cant use a 100uF or 200uF cap rated at 200v or something can I? Does capacitance vary with voltage change?
