So it's a PowerMate (https://en.wikipedia.org/wiki/Griffin_PowerMate) except made from concrete?

(Huh, apparently Griffin stopped making them in 2018, so I guess there's room for a replacement. I covet one every time I remember they exist but I never quite covet one enough to actually want to spend the money getting one...)

I have an older PowerMate (USB, not Bluetooth) that I used about 15 years ago in my first carputer. It's really good for that, better than relying on just a touchscreen. The carputer is long gone, but that Griffin PowerMate is sitting on my desk in front of me right now. Still wonder if I can find another clever use for it.

I've been using an ElGato StreamDeck repurposed as a global mute button (among other things) for Zoom, Webex, etc. The Powermate could be pretty nifty for this as well, using the radial menus to quickly get at globals like mute/unmute, start/stop video, etc

We're a small team, not a huge company. We've made this product open-source and free to use in our spare time.

The concept of the knob made of concrete is fully inspired by DIY Perks.

I'm not sure, but Griffin does not offer you all the perks I've described below:

- Open-source Arduino-compatible firmware so you can add your functionalities and light effects;

- The audio is controlled with the HID library instead of potentiometer; spare time - There are one audio input and two outputs that can be switched with the hardware switch;

- Bonus option is you can use it as a scrolling knob;

- The audio lines are connected to the microcontroller and you can add light effects relative to the sound;

- It is 3d printed and we also added a 3d printable model of the mold for the concrete part;

Have a nice day ;)

Griffin also doesn't actually make their knobs any more so anything you are offering is more than they currently are.

"Huh, apparently Griffin stopped making them in 2018, so I guess there's room for a replacement."

Teenage Engineering makes one of these:

It is designed as a remote volume control for one of their synths but it is a generic bluetooth volume control device that can be used with anything.

I have one - very nice and very high build quality.

How much of a pain in the ass is it to configure it to control things besides volume with it? Because whenever I think "it'd be nice to have a PowerMate" I'm never thinking about volume control.
