#README for Etchingbox project#

##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
