I'm hoping that maybe Tom and Jim might jump in here...
I'm looking for an "electro guru" out there that may be able to help me with a project.
I would like to isolate a circuit switch that is triggered by the ohmic state of my hypertherm torch head and the workpiece (basically a "touch-n-go" system) that doesn't fry my micro electronics on my CandCNC I/O board!
I'm NO electrical engineer... This is why I draw instead of talk....
Anyone want to put a RADIOSHACK shopping list together for me???
