    Hi everyone, I'm fairly hopeless with electronics and trying to build something nifty, so Ive decided the best way to do it is to break it down into individual stages and bother the internet about it piece by piece.

    1. I need to latch two alternating momentary signals at 10-150hz into effectively a square wave, ie: bip...beep.................bip...beep................ needs to become biiiipbeeeeeeeeeeeeeeepbiiipbeeeeeeeeeeeeep. I understand that a flip flop is the tool I'll be needing for this?

    2. One of the signals is +5vDC, the other is -12vDC. Will a flip flop IC accept this, or do I need to convert the -12v to +5?

    Thanks in advance for the help!

    That is called bottom-up implementation. Before you get into the details it is important to do a top-down design.

    Please show us the big picture.
