We are getting a lot of questions about the knob. Here is some info 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 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; If you are interested in buying one of the samples please email us, we'll try to figure something out. This way you will help us understand how desirable the product is. Thank you and Have a nice day ;)
