Got an unused airsoft gun from your guns are cool teenage years? Why not transform it into a Bluetooth handset that you'll probably still never use. A user at Instructables did just that by rewiring an older Jabber handset inside an airsoft gun. Even though it's probably the biggest and most absurd Bluetooth handset, the workings of it are pretty cool. The trigger has been wired as the call button, the barrel as the speaker and the grip as the mic making it perfect for taking calls with the wife when she finds out you stole her Bluetooth handset and put it into a gun.
