Dot Matrix Display controller board
DMD Controller Board kit
Received a DMD controller board today (in kit form) from my new friends at Flippermarkt.de. The idea of this kit is to not only regulate the overall brightness of the display (thereby extending its life) but also to allow easy fault detection (by simply switching on all pixels with the flip of a switch).
I’ll report on the results, as soon as I’ve built it up and connected it to the machine
