Step 11 Electronics of the Daleks, Part Two

The second part of the electronics are the all important voice activated lights. I had to fudge things here, I couldn't find a simple circuit to use with parts I already had, so I kinda cheated. If you know a simple voice activated light circuit, please let me know!

I used:

• A length of speaker wire
• A sound activated EL wire driver from coolneon.com (I actually won mine in the 2009 Halloween contest)
• 9 volt battery

The sound activated board normally drives 20 feet of EL wire. I played around with this a bit, and found that if I wired up the bulbs to a couple of spots on the underside of this board, they would work in place of the wire, take a look at the second picture above for the exact spots. I also detached the mic and put it on a length of speaker wire so it could be placed in front of my mouth later on.

The one real problem with this circuit is that it makes an annoying whine whenever activated, so again I would really like to try a better circuit if you'd like to recommend one.
