I would like to build an electronic board that can input 120v wall plug in, and output to a laser 5mw (I'll start with one laser head, but maybe have 3 outputs???) that I can alter the frequency pulse (say 10 Hz or 40 Hz, or 1000 Hz) and possibly have a timer on it so I can "set it and forget it". I am a novice with this (and is this a novice project??). And I suppose I could build a 3D print of a box to put it in.... TIA.
