Bluetooth Headset mod with LED's Answered
I have an idea, I need a good starting place.
My father is deaf. I want to get him a cell phone and send him SMS text messages. I obviously don't have to worry about him running up minutes on my cell plan. What I want is a bracelet or watch band that lights up with LED's. The LED's would stay lit up until a reset button of some kind was pressed. The phone would have to be linked via bluetooth with some kind of handset protocol that would set off the LED's.
A fake watch would be ideal. The watch innards could be big enough for the bluetooth circuitry and the battery.
