• Different modes (amps) for mic, contact mic and pick-up
• Builtin VCA
• Builtin envelope follower

Bonus feature: XLR with phantom power

Imagining basically a mixer circuit where outputs of amps can be routed back to inputs to create feedback. Possibly multiple. Include a mcu with ADC to detect levels at certain points, then control the feedback via digital pots with the mcu. With detecting level + ability to control feedback, I'm imagining a sustained tone could be created that would be kind of dynamic. Depends a lot on how the amp circuits are made. Would probably include some filtering in the analog realm too. DAC possibly as well, to do some DSP. But the main focus would be controlling feedback by detecting levels and dynamically adjusting gain. Could have an input too.

Unlicensed operation on the AM and FM radio broadcast bands is permitted for some extremely low powered devices covered under Part 15 of the FCC's rules. On FM frequencies, these devices are limited to an effective service range of approximately 200 feet (61 meters). See 47 CFR (Code of Federal Regulations) Section 15.239, and the July 24, 1991 Public Notice (still in effect). On the AM broadcast band, these devices are limited to an effective service range of approximately 200 feet (61 meters). See 47 CFR Sections 15.207, 15.209, 15.219, and 15.221. These devices must accept any interference caused by any other operation, which may further limit the effective service range.

Crazy but simple idea

Lua controlled am radio tracker

Track songs with lua. Something like moonforge.

Transmits ONLY via a AM radio.

No DAC.

Another kind of easy example might be to take a few different capacitive touch sensors and do the same thing.

IMO doing this for buttons doesnt seem super valuable to me since as far as I know almost all buttons have the exact same outputs. There really is nothing to abstract there is there?

I think pots are a really good example since they have different curves and ranges but in theory could be abstracted to always output a linear value between 0 and 1.

By always doing exactly that, we can write code that takes that and creates its own curves and other behaviours and never need to worry about the specifics of the pot it gets the data from. The same code could work the same way on two completely different pots.

Proof of concept would really just be taking two totally different pots, run them against the exact same "high level" code and see that the code results in the same exact outputs.
