There is a giant LED sign at the shop. I am very lazy so I am not going to tell you what kind it is. However, I do know that the python library for Alpha American and Betabrite signs will drive it just fine.
The current code was written by User:brimstone, I believe, before there were really libraries out there for using the sign. So the protocol was written into the script by him. I (User:hfuller) am working on a rewrite based on Python, so that we can use the ready-made library. Once this is done, I will work other capabilities into it so that it can be controlled via REST API and ultimately via RQ.
Status of new code
There is now Python code that will do the same thing as the old Perl code. I'll use this as my starting point for further dev.
Goals
- Continuously update the sign in an "inexpensive" way so we can have a more accurate clock and other readouts.
- Add extra screens for stuff like alert and other messages.
- Expose all relevant functions over REST, especially the extra screens for alert functionality.
- Tie the extra screens and default screen into RQ.
