LED Sign

The PLSE sign is a LED sign hanging in the lab that displays various things, like a Game of Life binary clock or deadline countdowns.

To start a deadline countdown, run /deadline sign [conference], which uses deadbot’s database of conference deadlines.

The sign can also be programmed. You write Python programs that run on the computer controlling the sign; this Python program uses a library to send drawing commands to the Arduino controlling the sign.

To program the sign, ask Stuart to get your key added to plseaudio and check out the repository

debian@plseaudio:/srv/plseaudio/sign/sign-code.git

Any time you push to that repository, the sign will restart automatically with whatever changes you made.
