Polls URL (https://api.my.protospace.ca/stats/) continuously and looks for changes to the vestaboard key. When updated, it replaces any special characters and then displays the message on the sign via serial.

If you want to use this, just call send_sign(text) in protoflap.py directly.

The split flap controller is connected to serial at /dev/ttyAMA0, 38400 baud.

Setup

Download the Vestaboard root private key. It should be the same for all Vestaboards:

$ curl https://files.catbox.moe/kvibj6 > ~/.ssh/vestaboard
$ chmod 600 ~/.ssh/vestaboard

SSH into the Vestaboard using the root key, ie:

$ ssh -i ~/.ssh/vestaboard root@10.139.85.133
