Blinkström Colour is a BlinkenLights clone that can display full colour animations.

This project uses the BlinkenPlus firmware on an ATmega162 controller. On the PCB there is an SD card slot as well as a level converter and solder pads for an RS232 serial port for streaming input and output.

Hardware

The LED matrix is divided into 18 columns and three times 8 rows (8 each for red, green and blue). The multiplexing is going across the columns from right to left, so only one column is lit at a time. The refresh rate is 100 Hz for the lowest brightness level and increases for the higher brightness levels. The board has to be supplied from an external 5 V power supply capable of at least 0.8 A.

The 3.3 V power supply for the SD card is generated either by two silicon diodes in series or a 3.3 V regulator. If the diodes are used, C10A (100 nF) is populated, for the voltage regulator C10B (1 µF) is necessary. R38D is a basic load to prevent the voltage from becoming too high when no SD card is inserted, especially when using the diodes.
