Case for DAOKI DC-DC USB Buck Boost Converter
Description
This case is for a [DAOKI USB buck-boost converter](https://www.amazon.ca/gp/product/B08M34RXJW), which you can get from Amazon. I have a USB LED ring light that I've mounted to my CR-6 SE. The light has an inline controller for power, brightness, and colour temperature, but that prevents me from turning the light on/off automatically with my printer. I cut off the USB controller and wired the LEDs directly to the DAOKI buck converter, which enables me to turn the light on when it receives power. The converter enables manual dimming with a thumbscrew, so I set it to 3.2V (the max output of the controller). There are two small switches on the converter. The first one cuts and restores power, and turns off the display with a long-press. The second one cycles between showing voltage, amperage, or both. Whenever you plug the converter in, it always defaults back to turning on with the display showing voltage. The case has a window to see the display, built-in buttons for the controls, and holes for the thumbscrew, USB-A connector, and microUSB connector.
