April General Meeting
Dot Matrix Display Pinball Clock
Speaker: Chuck Rohs
Chuck has been building a pinball machine for the last four years. One of the many sub-projects (rat holes?) as part of that endeavor was tinkering with DMDs (dot matrix displays). He has built a standalone DMD "pinball" clock as a result of this effort. It is called a pinball clock because it displays animations from popular 1990s era pinball machines in addition to the time.
Chuck will present:
- some history of similar clocks
- the workings of the (LED variety of) DMD displays
- an overview of the hardware, an rp2040 based driver board
- an overview of the software
As a bonus, a clock will be running during the presentation, to give you something to look at in case Chuck is too boring or in case he attempts to talk too long.
Chuck has a background in embedded software development and security, and was a founder of Au-Zone Technologies Inc. He is currently retired and enjoys tinkering with embedded hardware and software.
