featured in the "Beyond the Phone" Wireless Charging Challenge
The tap is made from metal and features the product tube, as well as a cooling loop, and when in service is frozen with ice on the body.
Below you can see the tap in the ON state (at 50% brightness) with various colors.
The standard "Neopixel" ring was slightly too smal. However, as the final photos show once the product label was attached, the diffusion was sufficient.
When switched on, the illumination is white. Color change is performed by holding a magnet against the hall effect switch and it cycles through the rainbow. With the blue product label, some colors do not produce well, and since I don't have the full range of labels, the above is a good representation of the effect.
Check out the video for a short demonstration of the illuminated beer tap.
