DISCLAIMER: This is a lo-fi wireless audio system. In my mind, the sound quality and the freedom of motion is worth way more than what could be expected from about $5 and ten minutes of work, but these things tend to be subjective. If you want pure clean sound, you discriminating virtuoso you, save your pennies and spring for the $450+ professional version.
DISCLAIMER. Part II: Yes, I did actually make it, and it works. Sheesh...
Step 1: Get Your Materials
1. A set of walkie-talkies. Just about any variety in good working order will do. I found my "kiddie" style National Geographic walkie-talkies, batteries included, at the swap meet for a paltry $5. I'm sure I could have gotten a cheaper pair if I had been more patient, but I was rearing to try my idea out, and $5 seemed reasonable.
2. Two 1/4" audio plugs, male or female, depending on your preference. I actually just cut a guitar cable in half, and that worked out pretty clean. Doesn't really matter, basically you just want to run the signal from the guitar to the "transmitter" unit and from the "receiver" unit to the amp.
3. Solder, flux, soldering iron, maybe some hot glue. You know, the usual junk.
4. Might be good to have a Churro around, just to nibble on something between steps.
Step 2: Modify the Damn Things
Step 3: Designate Which Walkie-talkie Will Do What
Step 4: Rock Out!
Step 5: Options
1. Rehousing the units: Take all the guts out of the walkie talkie, and rehouse them in something more befitting a rock'n'roll monster such as yourself. Something with cobras or skulls and junk. Or, if you're feeling especially daring, something with cobras AND skulls. Another possibility is to house the transmitter unit within an instrument, like your cheap chinese keyboard or your circuit bent TMX Elmo. Imagine the possibilities for audience participation.
2. Utilize the "send tone" button: Most walkie talkies have a "send tone" button. Snot-nosed kids like to use this particular function to pretend they know morse code when they are playing army or between sessions of grab-ass. We can do better, right gang? Consider turning this into an on-the-fly guitar mounted optical theramin, or simply a loud-ass noisemaker. Not even the $450 dollar professional wireless systems have any bells and whistles like this.
3. Other products which can give similar results: Mr. Microphones, those crummy 80's devices and their inumerable bastard step-children (see Police Academy 2 for details) which transmit audio directly to your FM radio can be used in a similar fashion, with the Mr. Microphone as the transmitter and an FM radio as the receiver. Cordless house phones can be used if you know how to make them run off 9volt, but I'm not going to get into that. Anything that transmits audio from one device to another without wires is fair game. Who knows, maybe you can hack those hands free cellphone earphone/microphone adapters and jam with your buddies across the continent with your free nights and weekends. I'd try it myself, but I've never touched a cell phone, and I ain't starting now.
That's all for now, gang. Keep rocking the most.
