I was more impressed than my cat by the scrolling background of the "Tiny Space Invaders" for AtTiny85, so I adapted the code to work on Wemos Mini D1 with a huge 128x64 OLED display I bought from tindie.

I recycled the deauther box for the fridge ( see https://www.youtube.com/watch?v=bNIh7MjtLx8 ) by adding a speaker and a button.

Hardware:

• Wemos Mini D1 Pro
• SSD 1306 2.4 inches from tindie https://www.tindie.com/products/fred_IOT/242-monochrome-oled-i2c-display/
• PSP Joypad replacement breakout
