Retropie Zero cheap portable device

I designed this for myself. And i thought why not share it to the community.
Things needed:
-2.8" TFT SPI 240*320 LCD screen
-PCB boards to solder buttons onto
-Raspberry pi Zero
-Lithium Ion Battery 14500 cell
-Micro USB Breakout
-3V to 5V DC-DC Step Up Boost Converter
-Charging circuit for the Li ion battery
(A glue gun will come in handy)

For the start/set buttons i used microswitches that i bought from aliexpress some time ago and glued them down on the bottom case.

that's
