Sup, fellas. I am atm studying by myself some electronics (nope, can't describe better just because I don't know English that much) stuff and I came to an idea of fake bomb timer for my friend playing ASG.

Idea is simple to drawn.



Now, if there is any circuit-fan, I could use any help. I'll try to get tomorrow some help from my friend also, he's learning this shit in school.

I can plug all components into one working device.
I can buy all components.

The worst thing is actually drawing circuit of it, as I am not enough experienced to make own ideas.
