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 ;)
