I'm pretty much a novice with arduino, I've only done basic programs with my Arduino UNO kit, but I'm willing to learn and put some serious hours into what I want to achieve.
I work at an airsoft site and I want to create an interactive prop for a MilSim event we run. I am the resident pyrotechnician and have remote firers and an assortment of pyro articles but I'm wanting to go one step further.
I want to create a device where teams have to actually defuse a bomb. If successful, the device will shut down. If they do it wrong, or if the timer runs out, it will trigger small charge a safe distance away. The charges I would use are fired by using an ematch, which requires a minimum of 750milliamps to fire. I'd probably use a two or three at 2 second intervals to simulate a building self destruct.
I'd like to have a couple of ways to defuse it. 1) A 4 digit code that teams would have to find. 2) A key switch that would simply prevent any power going to the ematches.
I'd ideally like the teams to have three attempts at entering the correct code. If all three attempts are wrong, the device would reset the countdown to 30 seconds, at which point teams would have to evacuate the area.
I'd also like this 30 second timer to be triggered if teams attempt to defuse it manually by cutting wires - like old fashioned bomb defusal shown in the movies.
I have access to a 3D printer so I'd be able to design a pretty good wall panel that would act as the self-destruct control panel.
Thoughts? Is it possible, or am I being a bit too ambitious with what I want to achieve?
I solemnly swear I have no nefarious intentions!
