##The Idea##

Build a portable / mobile PCB etching workstation that fulfills these criteria

* waterproof

* able to etch 100x160mm double sided boards with 8mil precision

* low cost.  total bill of materials should not exceed 150 CHF

* diy approach, mostly laser cut plexi and easily sourceable materials

* fits in a RAKO Box

Some guiding ideas

* use very little but always fresh chemicals 

* good heat management: etching has to be done at 45-50 degrees celsius, developer has to be kept at >20 degrees as well (in my workshop, temperatures can easily drop below 16 degrees and developing is a pain).

* all material and chemicals travel in the box. liquid waste can travel in the box as well until it can properly disposed of.

* should be easy to clean. no electronics exposed to moisture. 

* as few as possible switches and electrical contacts exposed to the harsh etching environment

* self illuminating
