I have interest in making a random pulse timer.
I have a keyboard interface that I've matrixed out so that's done. I want to randomly (every 10-30 seconds[or whatever]) send a pulse to the keyboard interface.
About the keyboard interface. When 2 contacts are touched a keystroke is recorded to the PC. So I just need to bridge that connection when the timer goes off.
Timer has to be randomized too as I said above.
I can do soldering and all of that, I've messed with some schematics using 555 timers. But I don't have a clue how to actually design a tiny circuit like that.
