That’s a genius idea! You wouldn’t mind some healthy competition would you? I have some experience in circuits. I probable could create a sound/ flash grenade.
Competition... uh no, no problem (I have a MSEE) but okay. By the way the flashgrenade, doesn't actually flash, its audible. Once you pull the pin, 3 seconds later it 'Wails" at about 105dB (smoke detector is 85dB). The strobe is useless, since most ops are during the day and it is also a pain in the butt to have to put a boost converter in the flash bang to generate 100Vac+, so why bother. Everything in airsoft works on the honor system, so will the flashbang. For as long as it is going off the people already inside the room have to keep their eyes closed, but can still fire their weapons. Cheap, easy and safe!
I'm going to wait to try out the audible claymores that SWAIRTAC will be using, to see how to improve them and then start on the next 'gadget".
