Earlier quoted context omitted.

Thanks for sharing. They’re obviously inspired by that one from a materials point of view, but the technical implementation is far different. There are some major limitations on the YouTube one. First of all, it’s a potentiometer not a rotary encoder, so it has a start and a stop. Second, it is controlling an audio signal directly, not using a PC, so it is not usable in the same way. Audio would need to be routed thr…

To avoid any confusion: The concept of the knob made of concrete is fully inspired by DIY Perks. But we are added a lot of perks, like: - 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 opti…

Wow! That’s amazing level of improvements!

I’m glad people share their inventions online in this open way. It helps us all get better ideas. I hope you didn’t think I was saying anything negative about your new improved version! It looks fantastic.

Thanks for the details and thank you for sharing.

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...)

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…

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

Thank you.

The site felt like more like one of those old adventure game puzzles than an actual website with information.
