PCB Etching Machine. Save money and time....

Step 8 Bottom View and future improvement. Enjoyed....

This is the bottom view of my PCB Ecthing Machine....

Thanks for viewing...

I will be adding a stopper switch and timer control in near future.
This will allow the PCB stop at a predefine position (PCB and chemical separated) and etching time to be control. This is good because one can leave the etching machine unattended until the whole process over or come back next day.
