DIY Bluetooth Headset And Other Inventions

NETHED writes "Circuit Cellar has an blurb about a guy who obviously got sick of waiting for a cheap solution to the BlueTooth cellphone headset. So in true geek tradition, he rolled his own. Here is the description of the toy (which looks bulky as-is, but could be fixed w/ some refining). It actually didn't win any prizes in the PSoC contest, but you have to admit, its pretty cool. There are other honorable mentions like a poor man's O-scope to something that seems to attach to a moth and check its muscle movements. Neat and nerdy stuff for the circuit etching crowd."

Re:Why not simple RF?

I was talking about practical applications of this idea. If "security" is your concern, "forget" BT. The security it provides is worse than that of Wi-Fi.

I'd be very interested to hear you justify that. My BT headset is paired to my phone - it won't listen to anyone elses phone, and my phone will not listen to anyone elses headset. The phone and headset are not even discoverable unless I manually do something to them. Comms are encrypted and sent over spread spectrum. I doubt that the average phonecall lasts long enough to capture the gigabyte or so of network traffic that it would take to even begin to attempt to break the crypto, plus attackers would have to be within a 10m radius of my call which could prove to be a little difficult.
