The Matrix is an I2C controlled 24x5 LED matrix display, powered by an AMS AS1130 LED driver. It's made of 0.2mm thick circuit board so it can slightly bend. A few can be joined together for creating a larger display.
I've been working on a Tetris game that features the BoldPort Club "Matrix" project.
So far, it has the essential game mechanics, increasing speed with advancing levels, and scoring. Later I may add a high-score system.
The controller is a 5-way switch that I salvaged from a cheap webcam, although it's rather touchy.
I want to replace it with a rotary encoder to spin the pieces, and buttons to move and drop them.
I'm also considering adding 7-segment displays to show the level and score in real time;
right now the score is only shown on the screen when it's game over.
A stencil is not a requirement for building The Matrix. You will be able to assemble the kit as you would normally with a soldering iron.
If you prefer to use solder paste (which is another soldering technique that usually requires a stencil, solder paste, and other equipment) you are able to order the stencil from OSH Stencils. Totally optional.
Use this link to add the stencil to your order.
I just published version 0.9.0 of the LRAS1130 library on GitHub.
The library now contains everything you need to do simple things with the AS1130 chip. There are also three examples how to use the class. One of the example is a LED test application which checks all LEDs and writes the status to the serial console.
