# Tenet Brick #Tenet #SharpMemory #rpi A build in the [[tenet]] project. ![Image: a small computer, shaped like a brick, mounted on a tripod](IMG_5624.jpeg) This was the first prototype I built. It came about after a couple iterations of sketches and ideas. My goal with this was to learn how to connect a SHARP Memory Display as the main display for a Raspberry Pi. ![Image: A 2.7-inch 400x240 SHARP Memory Display, on an Adafruit breakout board. Shown here with a Raspberry Pi 4 for scale.](sharp_memory_display.jpeg) I discovered that while I can use the display (for a terminal), it is quite small. The model I'm using is 2.7" and 400x240 pixels. There's a larger model with the same number of pixels that I haven't tried yet. ![Image: Another angle of the Brick on its tripod](IMG_5644.jpeg) The display is monochrome, with no back- or front-lighting. It communicates with the Pi over [SPI](https://en.wikipedia.org/wiki/Serial_Peripheral_Interface), so some custom software was necessary to use it as a monitor.
