deej VS smartknob

You have some alternatives. For one you may look into the Deej sources, it uses python to manipulate the volume level of different apps/devices so maybe it's a good starting point.

It's a wonderful little project called Deej. I couldn't live without it at this point: https://github.com/omriharel/deej

The code and schematic for the electrical components is from a project called Deej https://github.com/omriharel/deej

Deej is fucking amazing.

I allready build a controller for different applications. Try usind deej. The one that build is also have a discord with many frindly people that helpt me a lot. https://github.com/omriharel/deej/releases

As the title says i've been trying to change volume of audio endpoints based on a serial connection via an arduino (sorta like https://github.com/omriharel/deej, but there are also buttons involved for macros and a ui via tauri). I've been experimenting with the windows-rs package to get it to work myself but i can't. can somebody link an example for this sort of functionality or a already made project with this sort of functionality?

The macropad is based off of Deej. There are a ton of remakes of it, so I made one for myself. The knobs are for volume on different programs.

good job! reminds me of a 4 slide potentiometer 'mixer' I build a while ago, based on https://github.com/omriharel/deej

...it's a spring and a servo. Or a brushless motor.

...or any not-bottom-end-of-market steering wheel for driving video games.

I made a rotary input device that provides software-defined "virtual" detents and end-stops, implemented using a BLDC gimbal motor. It can dynamically switch from completely smooth unbounded rotation, to having detents with configurable spacing and strength and "end-stops" that spring back if you try to rotate past them.

It's got a round LCD on the front of the knob (wired and supported via the hollow shaft of the motor) and uses the flex of the PCB and strain gauge sensors (in the latest revision, simply SMD resistors whose resistance changes when stretched) to detect when the knob is pressed down.

It's open source hardware and software - https://github.com/scottbez1/smartknob

HN folks might appreciate that it communicates with host software on the computer via protobuf-encoded USB serial messages -- nanopb is awesome for embedded C protobuf support, and having the defined schema, autogenerated serialization code, and compile-time type safety is so much nicer than ArduinoJson or hand-written binary protocols!

I'd love to get it hooked up to some real software eventually (video editors or home-assistant control are my 2 main ideas), but it's really just been a fun project to tinker with and try out some new ideas and parts I've never used before.

I'm trying to design a smartknob based off Scottbez1's design (https://github.com/scottbez1/smartknob), but with a stripped down feature set. However I can't seem to get the magnetic sensor to work properly - it's an MT6701 connected to an ESP32 via SSI.

Thank you so, so much for finding it. Unfortunately on eBay its not cheaper and ali doesn't have it cheaper either. It looks like an out of production item, like when I wanted to make this https://github.com/scottbez1/smartknob and it was gone except when sparkfun got a few.
