Im currently working on a Wire cutter/stripper loosely based on this one: Arduino Automatic Wire Cutter and Stripper
I would like for the unit to shut itself off after it has finished a job and I found several examples to follow but they are all for battery powered systems. I am hoping to add a capacitor to power the circuit until the power supply comes online.
I chose this circuit(EEVblog #262 - World's Simplest Soft Latching Power Switch Circuit) to start with making only 2 changes so far.
move q3 to the other side of switch S1 and eliminated the R/C combo to allow the arduino to shut things down.( I just realized I will have to add those components back in to allow the switch to also shut off power DOH! )
Added a capacitor to initially power the circuit.
I'm guessing it's not that simple and I'll need to do more to get this to work. What do ya'll think?
