Nantendo LED matrix console game

thingiverse

I've created a handheld game console inspired by the Nintendo NES controller, featuring an 8x8 LED matrix display! Update April 2017 - New firmware integrates Doodle Jump with other games and adds Flashy Bird and sound effects. I had a batch of PCBs professionally made, available for AUD$10 + postage on eBay. This project is based on an Arduino Nano and a 1.2" 8x8 LED matrix display with a HT16K33 driver. Both are affordable options from eBay. The build cost should be under $20, assuming you can create your own PCB. The 'Nantendo' firmware includes Pong, Space Invaders, Snake, Breakout, and Car driving games, as well as the weird game Tedshow. It's adapted from a Let's Make Robots project with some notable differences: using a different display driver and buttons for left-right control. Alternatively, there are adaptations of DoodleJump based on this GitHub repository and another version with sound effects here. However, these projects have stability issues. Instructions: 1. Print parts according to the Bill of Materials. 2. Print the label onto adhesive material and cut it out with a scalpel. 3. Make the PCB from Eagle files. 4. Assemble the PCB. 5. Copy Arduino libraries from the 'Arduino_Nantendo.zip' folder into your own Arduino library folder. 6. Load the firmware using Arduino host software and a USB mini cable. 7. Assemble the housing. 8. Get playing! PCB assembly notes: * If your 8x8 display comes with right-angle header connectors, remove them by cutting the pins, pulling off the plastic part, then carefully desoldering each pin - see photo. * Use a 4-way straight header to connect the display to the PCB. * Optionally, use printed spacers and M2 screws to steady the top of the display. Alternatively, you can screw into the PCB or use thin double-sided tape between the boards.
