What is an example of an audio controlled toy?! Does that mean voice commands, or does that mean some sort of high-frequency (outside human-audible range) binary channel? I looked but did not see.
- the8472 6y agoperhaps the audio port (6.35mm) providing a data channel?
- FeepingCreature 6y agoThat is correct. (Though usually 3.5mm.)
- qdot76367 6y agoThe only places we usually see RS-232 (either swing or TTL) over TRS is estim, funny enough.
- jrockway 6y agoMy Elecraft KX3 radio's computer link cable is almost the same RS-232 over TRS pinout that the ET312 uses. I think one pin is different, though, and had to build a sort of crossover cable.
- qdot76367 6y agoOk, since you're familiar with the ET-312... You know we reversed the ET-312 to the circuit level, right? :) https://github.com/buttshock/mk312-bt https://github.com/buttshock/mk312-bt

- jrockway 6y agoYeah I've looked at that a number of times. I always thought it was cute that they went to so much effort to scrape the part numbers off the ICs.
- qdot76367 6y agoSo, audio stuff is still a bit of pipe dream, but I want to at least try at some point. Easiest would be something like what OhMiBod puts out, which is basically just a vibrator with an RC band pass filter as speed control. We could generate audio to work within the sensed reaction range there. Electrostimulation toys also use waveform input, since it's translating signal-to-signal basically, but that's a whole other huge discussion. Finally, if you consider HD Rumble (think what's in a Switch Joycon or VR controller), those also take audio buffers since they can deal with far higher update rates than eccentric motors.
