As @tehlike said in a sibling comment, it looks like it is supported by https://thingino.com, so you can 'update' the firmware to a more secure (and FOSS) one!
I made a home-brew seismic sensor using something similar, a hard disk head arm assembly, a cd-rom laser (which has an anisotropic lens and four photodiodes) and a Red Pitaya used as PID, so I guess it can be done!
Last shipment of components shipped today, so I'll soon build the project I mentioned [last time](https://news.ycombinator.com/item?id=41700806), a remote for BabyBuddy. Main features are:
- 10 switches that I can assign to start/stop timers and trigger events (Kalih Choc Robin)
- One encoder + four way directional switch
- Round LCD display with touch
- 9 DoF IMU and ambient light sensor
I've started coding the firmware using Rust with the excellent embassy OS.
Late to the party - I'm building a "remote" for https://github.com/babybuddy for my future child. It's based around an esp32-s3 and has:
- 10 switches that I can assign to start/stop timers and trigger events (Kalih Choc Robin)
- One encoder + four way directional switch
- Round LCD display with touch
- 9 DoF IMU and ambient light sensor
If we won't use it for our child, I'll use it as a slightly overpowered macro keyboard :D
Of course I intend to publish it as soon as I have the first prototypes debugged!
