My DIY PCB Etching Machine

[matthai]

This is my simple etching machine using scrap.

Very nice. I believe I see a cam at the end. I guess it moves up and down? To keep the etching liquid mixed? So you don't have to stand there for 15 minutes shaking the tub?

great!! whats the function of the laminator? i use my laser printer for toner transfer on glossy paper but the transfer is not good at all

Very nice indeed, specially first image in post#3.

@Tipu606 :

From my expirience use HP LaserJet with higher resolution 600dpi or best is 1200dpi, with high density toner.
Major thing in this process is right paper and proper heating iron and temperature.
From my expirience best paper is Verbatim Glossy Photo Paper 150g (only one side is right for printing).

Uses a different principle so the cam doesn't have to lift the whole weight of the tank and fluids.
