Boba Fett Voice Changer Build?

Has anyone made a voice changer from scratch or found one that fits int he bucket? I am also looking for a speaker system to install for my son to hear his surroundings. Any help with these would be greatly appreciated.

Look up Deathproof's WIP thread. He did more with voice changers than most. He didn't start from scratch but put a ton of effort in.
Hearing can be a challenge. I have my Aker for voice amplification, but it doesn't' do anything to pick up sound. It's only one way. Aker is probably the standard voice amp. The speaker fits into a pouch and the headset fits under the helmet pretty easily.

Here is a thread about hearing aid system:

I ordered a "make your own amp" from EBay for around $4. If you have any electronics experience, this is a pretty okay way to go. Even if you don't, it takes no time at all to learn. A soldering iron can be as low as $6 and solder $3.

I wired in a cheap mic to my helmet and hooked it to the amp with an old airsoft battery I had. Works pretty well, the slight distortion from using cheap parts is a little more Stormtrooper-ish, but I like it.


Then there's always this kind of thing: http://www.spirithalloween.com/prod...ive=41364064906&device=c&matchtype=&network=g

Which should be cheap and easy to find with the upcoming holiday!


Good luck
