WIP Cheaper Gameboy Nano - Raspberry Pi Zero

thingiverse

NOTICE: I have suspended work on this project until I get get the SPI screen to work. Read more Here WORK IN PROGRESS (WIP): Not all files are uploaded, pictures are out of date. More to come. Button panel prototype not completed As of 5/26 I have not found a way to use this screen to play games (or use it as a display at all, but I can send pictures and text.) Read more here: https://www.raspberrypi.org/forums/viewtopic.php?f=44&t=143815 This is a remix of Rasmushauschild's Game Boy NANO using cheaper parts from chinese ecommerce sites. It can cost as little as $35, the price of the original raspberry pi! (although with larger sd cards, better chargers, etc it can be as much as $60). You can buy your parts from anywhere, but I got most of mine from aliexpress.com. Initial tests show that despite the low resolution, it could be used to play older games like arcade, NES, Gameboy, and the like. School ends next week so I should be able to put more time into this. Here is a video of one of the first tests I ran: https://youtu.be/DjBTgE7AdzY (sending commands to screen, not from the actual console) The TFT LCD screen is identical to the one used by Rashmushauchild, but uses a different board and costs 1/10 the price. I am trying to get the driver to work Here. I chose the battery because it is almost exactly the same size as the pi zero, but still big enough to power it for at least 2-3 hours. I have tested it for at least 2.5 hours on one charge, with the screen on, wifi adapter plugged in, and the pi running updates (max cpu) for most of that. Tools needed: -3D printer (duh) -Soldering iron -Hot glue gun -Small Flathead screwdriver (to push things into place) Parts list: -1.44 inch SPI TFT with BLACK board (the red board might work, but is not tested. Get the black verision to be safe: http://goo.gl/gaNI1B) -Raspberry pi zero -1000ma Lipo Battery (like http://goo.gl/C9mSdb) -Lipo charger/regulator all-in-one. I will have three adapted cases uploaded: Cheap chinese charger (still researching), expensive Adafruit balancing charger (https://www.adafruit.com/products/2465), and the old cheaper Adafruit one I am using (https://www.adafruit.com/products/259). -Micro SD card with Raspbian (Debian and other similar distros might work) -Small slide or rocker switch (multiple versions coming) -USB OTG adapter -A way to connect to the Pi Zero (TV+Keyboard, USB WiFi adapter, USB Ethernet, other pi, etc) Instructions: Coming as soon as I actually finish this Print Settings Rafts: Doesn't Matter Supports: Yes Resolution: 0.1-0.25mm Infill: ~15% for thicker parts, for shell use 100% Notes: Pictures shown used 0.25 layer height at 15% infill on a Makerbot Mini, but I printed the shell on its side because printing it vertically made the walls to weak. Lower layer heights will improve the overall aesthetic appeal, but will take longer. ABS is preferred over PLA if you have a choice because PLA supports are much harder to remove (and make it easier to break the part by accident), but either will work fine. How I Designed This Calipers and Solidworks. I drew each part individually and put them together in an assembly. The parts don't fit together in SolidWorks because I toleranced them for the 3d printer. I drew the battery and the pi zero as one part for simplicity and because they will be glued together.
