I’m helping to get Ada ready to welcome people back to building 99. Hopefully as the COVID-19 situation improves that won’t be too much longer. Ada is lots of fun to play with. The software brings together a bunch of interesting parts…
AI cameras recognize facial expressions, the predictions go to the Azure cloud, from there a server in building 99 orchestrates the lighting design which includes all the LEDs inside Ada and some big DMX par lights to add more dramatic effects. The Server sends the information to 3 raspberry pi devices which forward it on to 3 Teensy 4.0 devices which drive the long LED strips with very precise microsecond timing.
The whole thing is powered through 2 Kasa HS105 switches so the Server can put Ada to sleep every night. These switches connect to a little Raspberry Pi Zero that is running a private wifi network just for them and the pi zero communicates with the server.
There is also an Azure blob store for publishing new firmware for the Teensy’s so we get some nice over the air updating of the firmware when needed.
