Airsoft prop BOMB or DOMINATION internal electronics..
It runs from an Arduino system and is powered by 7.4v Airsoft lipos.
You are bidding on a complete and working interna l device for either a bomb or a domination game, that you will then be able to make into anything you like, I can put it into a very simple tupperware box configuration for an extra £25, but if you want something custom like mine it will be more depending on complexity.
You program a 4 digit code and a time limit up to 100 hours.and hit start, the device will then count down until it fake detonates with flashing LEDs and a buzzer.
If you input the correct code it will be disarmed, if you attempt the wrong code it will remove half the remaining time and increase the speed of the countdown
In the pictures is my personal bomb used for Airsoft games at my local site and has now been sold but I can make one similar if that's what you want for around £150
