PC Power Supply Etcher Plans?

[Fross]

Hey guys, where can I find plans, or do any of you guys have any experience doing this? I have searched and searched and it seems all the links are dead that had anything to do with this. I have a pretty old power supply that actually has the on/off switch on it and want to use it to make a better etcher, mine is just a phone charger with alligator clips and I dont have much control over it and I am ordering some stencils from Ernie this week. Thanks for the help!

I use a PC power supply,but mine does not have a on/off switch.
All I did was find the two leads that had 12 VDC,mine is like 11.87 VDC.Put your clips on those two leads,clip the pos.lead to your blade and clip your Q-Tip,that's what I use, to the neg.lead.After you power it up, and wet your pad,touch it to your stencil about 1/2 to 1 sec.increments until you get the etch you want.For me I could not leave it on for any longer,or it would burn my stencil up.

I go around my stencil about twice,I then stop and let it cool for a few sec.
Hope that helps.

God bless,Keith
