A project log for LED Tetris (Ledtris)

Classic NES version of Tetris on a DIY LED Matrix Display

I recently designed a PCB with a score display, ATmega8 and a USB->serial converter (I chose to use a CH-340, because it's ridiculously cheap.) The score display consists of a 6 digit seven segment display driven by a MAX7219. I could have driven it using the ATmega8, but I would still need a bunch of transistors to drive the cathodes of the display, so in the end this was the cleanest solution.

I will release the gerbers once I have tested these boards.
