Inspired by all the stuff on here, I made this:
I'm calling it the GB Null. It has a 2.8" ili9341 screen (thanks for the guide moosepr), 1000mAh battery (I'm getting about 2-3 hours battery life), TP4056 charger, and a Raspberry Pi Zero W. It's 134 x 56 x 17 mm (+nylon bolts).
I didn't want to layer the battery on top of the other parts as this leaves you with a thicker device, so I figured out a way to lay it all out side by side, I also made sure all the buttons were on the top and bottom edges as it really annoys me when a power switch or charge port is placed right in the middle of my palm.
I designed the PCB in Eagle and had it made through PCBWay. The boards came out great:
The case and buttons are all 3mm and 5mm layers of clear laser-cut acrylic with only the buttons and back 2 pieces being bonded together (solvent). This made it about 5mm thicker than it would have been if I 3D printed it, but I REALLY like clear acrylic and this way the screen is covered and safe.
The back part
Close up of how the right-angle buttons work (excuse the slightly messy glue)
And then a custom theme to finish it off
Hope you all like it!
When making a kit, put kapton tape across the bottom of the Pi to ensure that none of the other pads are connected.
