pockeTETRIS: compact Tetris clone using ATtiny85 and OLED

[dombeef] originally built pocketTETRIS as a Father’s Day gift for his Tetris-loving pops. However, having finished the project he’s decided to share it with the universe, and it’s looking rather sweet. He made the game the smallest he could make, with size limitations imposed by a 0.96” OLED display, the coin-cell battery pack, and his desire…

SSD1306 1.3″ OLED SPI breakout board

Rene van der Meer designed this breakout board for a bare OLED display:

SSD1306 1.3″ OLED SPI breakout board

I’ve been playing with cheap OLED display breakouts for years, incorporating complete boards into my projects – an easy, but bulky solution. Now that I’ve had some practice designing circuits and PCBs, it’s time for my next challenge: soldering the display FPCs directly to my own boards.

I designed this board to try out a minimal circuit before integrating it into any larger projects, and to figure out the best way to solder flexible circuits to my boards. Since all of my new microcontroller-powered board designs only require 3.3 V, I haven’t added any 5 V tolerant level shifting. What’s left is a bare minimum circuit to drive a Solomon Systech SSD1306 using SPI at 3.3 V.

MicroUSB powered ESP8266 OLED Board

I created this design as a challenge to make a design under 1″ x 1″ in size.

 The hardware is an ESP-01 ESP8266 Wifi module, linear power supply, microUSB connector and a few oled display parts.

The design files and source code are available on GitHub:

I’ve been keeping an eye on the SSD1331 library to see if it would eventually work with the ESP8266 wifi modules. I noticed the support for it appeared one day with the Adafruit library so I tried it out on my Adafruit Hazzah and success!
