re: Project Etching device

Thanks again all…

Kenny, all your points are valid and we’re addressed during tasting. The pics don’t necessarily show all those alterations, however they’ve been made. I can hear and see the etching (bubbles) when on DC. And yeah, the wires were reversed originally but changed over before testing…remember the comment on your thread about switch direction?

I do like the applicator you made though, I’ll have to knock something up like that. In later tests I was balling up the pad a bit and applying manual pressure, which got better results. 👍🏼
