The project should be fairly easy to complete. Most of the parts are plug-n-play, so the main task would fall to programming and design.
The major problem with this project is that the entire design hinges on the Pi Zero. I chose the Pi Zero, not just because of its small footprint, but because of its low power consumption.
Programming can be done on the model B+ for now and transfered to the Zero once I aquire one. So I may tinker around with that in the near future.
I plan on making the case out of wood, unless I can come across a 3d printer.
nice idea. in my opinion add good keyboard similar Psion 5 for terminal and big power for 24h working.
