I was looking around in the Arduino world and found some funny Inspirations for old games like Pong or Space Invadors running on Arduino.
So I made some "Play Boxes" with 1.5 Inch OLED display and made many adaptions to some free available Arduino code to get the basic game code running on Nano / Mini / Micro.
I Included a 3.7 Volt rechargable powersuply and the possibility to program the Arduino and recharge the accu over the same USB plug. 3.7 Volts works perfect.
Meanwhile I have a set of different Versions...
was also a good learning for my selve made CNC to engrave and cut the PCB.
The free pins are accessable from outside via an pin plug so the Boxes can be used for many other Arduino programs or Sensor applications in combination of the OLED the installed knobs and potis or rotary encoder.
