Here's the thing... I am making something.

I have taken apart an old dancing cactus that responds to sound. I want to use the sound sensor and the circut board (3volts) to run a 9volt motor and two 110volt appliances. I can't use a 9volt bnattery to run the board, as it would undoubtedly fry it. (or would it?)

I have the second half of the thing set up, relays, wiring, the whole bit. It all works perfectly when switched with a 9volt battery. The problem is that the activation signal has to come from the circut board, which runs of 2 AA batteries, 3volts, whereas all of the relays that I can find need a minimum of 9volts to operate the electromagnetic coil.

So here's my question...

Can I buy a 3volt to 9volt converter? or are there 3vot relays out there? If so, where?!?!?! I've been looking all over the web for this stuff, I think the problem is that I just don't know where to look. I've been to my local RadioShack a number of times, and they've hooked me up with all the other stuff I need, but they don't deal with 3volt doo-hickeys!

Maybe I'm barking up the wrong tree...

Oh well. thanks in advance.
