When I was designing a backpack system, I thought the best method to measure force was via a tube and an air pressure sensor.
The end of the tube could have a bulb on it which could be squeezed with a hand or in your mouth.
Hall effect sensors used in remotes like the maytech probably use an I2C chip, which means you could probably swap it out for an air pressure sensor and use the same throttle calibration process.
Using air makes the connection methods cheap and easily replaceable incase it is broken, and there would be no electronics in your mouth.
Sounds interesting!
I recall seeing something similar before (possibly your suggestion), but I didn’t fully grasp it at the time and dismissed it, thinking it was related to blowing air.
Also the advantage of a balloon is that it provides tactile feedback of contraction.
Using electronics somewhere near the head is inevitable anyway, since it needs to include a battery state indicator and power/lock button. But it could be split somewhere on the backpack strap in front…that is an option
Regarding engaging maytech - are you specifically referring to using their receiver rather than the remote control unit?
Could you clarify which calibration process you’re talking about? Is it the one done using the Maytech remote?
I’m curious about why we need to use proprietary remote hardware at all - wouldn’t it be simpler to perform manual calibration and use ESP32? Is it that hard to calibrate throttle?
Also, I’d be interested to hear about your backpack system…
