In this instructable I'll show you how to build a wireless intercom for short-range two-way communication. You can use this to chat with another person on a bike ride, or on motorcycle rides with helmet-mounted bluetooth headsets (that's my next instructable.), all while sharing your music or podcast (from iPod, cd player, etc.) This one is almost too simple for me to take credit for, since I'm really just repurposing a bunch of things and just making a very simple adapter to make them work together. That's good news for you though, because that means it's very simple, and though it's unlikely that you'll have everything just laying around, at least some of you will have a couple of bluetooth headsets handy.

So you'll need a few things for this, first you'll need to search eBay for "Motorcycle Intercom". Amongst all of the really good (and expensive) intercom systems, you'll find the very inexpensive (usually around $25.00 shipped) wired intercom systems that use standard 2.5mm cellphone headsets. These can probably be used for other things, so don't throw them away, but put them aside. We wont be needing them.
Next we need the Jabra A210s (or any bluetooth to 2.5mm wired adapter). I found these cheap ($20 each) at cell Xpo, link, so I used them over the Cardos, which were about $50.00 each. These will plug into the motorcycle intercom module where the wired headsets would have plugged in. See what we're doing here?
In my intro page, I mentioned that very basic soldering is required, but if you get one of the el cheapo intercom systems and find that the connectors are 2.5mm, you actually wont need to do any soldering at all. Mine is actually different from the ones most commonly found on eBay, and had 3.5mm jacks, so I needed to adapt the 2.5mm jacks to the 3.5mm ones on the intercom.
Lastly, you'll need to buy a couple of standard Bluetooth headsets. If you're in the states you're in luck. Recent legislation in my home state of California has required that anyone using the phone while driving do so with a handsfree kit, which means a bunch of online retailers are making great deals on Bluetooth headsets. I got a two pack on buy.com for $20.00.

It's amazing what a little bit of time does to things.
Dragon now has a Bluetooth headset called callpod V2. You can find them under 20 bucks with free shipping(got mine from wally world for 9.97 with free shipping to the store). They let you connect 2 of them together just like you would connect 1 to a cell phone. Advert says when 2 are paired together they work over a 250,000 square foot are(I assume this would be a circular pattern). Not sure how far apart that works out to but should be plenty to use for this.

The adapters are cool because you can plug them into your home cordless phone, mp3, cd, tape player, etc... and go wireless.. up to 20-30 feet that is.
any one know of a specific one that does?
