A comment on Show HN: TheKnob – sound volume control knob made of concrete and RGB lights. Parent comment
Right, the concept of the knob made of concrete is fully inspired by DIY Perks. But we've added a lot of sugar:
- 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;
- 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;
