Do you still remember Sarge’s ammo counter in the Quake III intro? Having heard the beep of his machine gun to signify that he’s out of bullets, he decided to go out in glory by jumping straight into a bunch of stooges, only to be transported into the arena where he battles with other “gladiatiors”. Well, a somewhat similar ammo counter is now available for automatic weapons, although this is a DIY project by Michael Ciuffo. An accelerometer will detect the gun’s recoil and keep count, where this means it can be calibrated accordingly to cater for different weapons. Apparently, Michael has received enough enquiries into his project that he is going to start producing it for the mass market.
