I was able to use the sensor readings from a Perifit device (old version) connected to my mac to drive a vibrator using the same logic as the edge-o-matic 3000. There’s some issues with bluetooth connects/disconnects that I’m still working through (that I think I have solved but still need to test more).
If people are interested, I’ll release the code + port it to XToys once I’m confident it’s in a v1.0.0 shape.
