For a friends bachelor party we played LaserTag at Lasergame Berlin. And we provided him with the ultimate weapon: a grenade, in form of a cock.
The equipment (taggers) used there are manufactured by HI-Tech. The manunal (backup) indicates is uses a infrared signal which is pulse-width-modulated (PWM) at 56kHz. On top of that it uses the MilesTag 2 protocol.
I re-implemented the explode command on a TV-B-Gone Troopers conference badge. I also changed the 38 kHz infra-red demodulator of the USB Infrared Toy from Dangerous Prototypes with a 56 kHz version. And using custom scripts I could record and decode the MilesTag commands. This way I can verify the data transmitted by the badge.
And finally I put the code on a custom board, and placed it inside a penis vacuum pump.
