Thats fine, I am interested in all of this stuff. I am in the process of building a AC/DC etcher right now. I have a 16 VAC converter and a 12VDC 1 amp converter all the switches I will probably have it finished by the weekend. I might put a dimmer knob in line to control the power but I will try it as is first.
I will have a center off toggle switch so I can go from AC to DC and click them on and off really fast for a good etch.
