Hi all.
Just found some mini Bluetooth headsets at Cable & Wireless for £2.50.

I bought four, and confirmed that they work although the pin code is a bit complicated.

Does anyone have a use? Thought about using them to send data from a model helicopter as the PCB is fairly light (and BT happens to be license free and the same tricks used to extend wifi also work such as using a foam tube with tinfoil covering)

Regards, -A

here in the US at least, there are these bluetooth adapters for phones that do not come with it, so the headset jack is used to send and receive audio from a bluetooth module... now that just about every phone has bluetooth built in, you can get them here for around $1.95

Interesting. The battery on these units is pretty tiny, you could fit 6 of them in the same volume as one PP3.

Not sure what kind of compression the audio on a bluetooth headset would be, I'm sure there is some. Which could be a bit of a hinderance.

Wireless link for an audio modulated tesla coil?

Tesla coil phone handset?

Hmm. Thought about using them to send/receive data from another project.

Shame that BT is so complicated to implement on Windows, otherwise I could program PIC's from a mobile phone and other such tricks.
