AETZBOX
DIY Mobile PCB Etching KIT
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

Questions
How big is the Aetzbox Power PCB?
It measures 36.9 × 32.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Aetzbox Power use?
7 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Aetzbox Power KiCad files?
From the mirdej/etchingbox repository on GitHub, at the commit this page was made from: the board is Electronics/Aetzbox-Power/Aetzbox-Power.kicad_pcb and its schematic Electronics/Aetzbox-CPU/Aetzbox-CPU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Aetzbox Power design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
