Hi everyone. I registered to this forum because a friend of mine who is not skilled with the English language needs help with a project. Ive been a serving member of the Canadian Army Reserve as an infantryman for 2 years now and proud member of a milsim paintball team for over 3 years. This friend of mine is working on a paintball project and needs help. I would have posted this in the project thread but I cannot because I have under 25 posts.
My friend basically wants to build a safe electronic "flashbang". He has a couple disposable camera flashes and a door alarm bought at a dollar store.
The flashbang must
- Have a timer of 1.5 second that starts the flash and the piezo
- The circuit must not take more room than a D battery
- The alimentation has to be very small in size, maybe some small batteries in paralel for 4,5 volts (not sure what the last sentence meant, hes the electronic expert)
-It has to be durable as it will be thrown around quite often and
-It has to be easy to repair
Any help would be very appreciated, thank you very much.
