MayorMike, inspired by the article I wrote for Make vol. 20 (Retro Wireless Handset), stuck a bluetooth headset in a plastic toy gun to create his Handgun Bluetooth Earpiece Project. The best part – the earphone is located at the end of the barrel, so to answer a call, you stick it up to your ear. Genius.
The innards are shown below.
Nice work, MayorMike! May I suggest that you pair this with a Hand Grenade MP3 Player?
