Have us print this for you
PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
A new invention to help with Christmas lights troubleshooting and other electronics hobbies! This combines a power supply, digital buck/boost converter with display, and a 2-port pixel controller.
What do you get? A lot! it can test two strings of 800 lights (Ray Wu and xConnect supported). It will test any pixel voltage (5, 12, 24V). You can dial-down the voltage to see how the lights work with low voltage (a common problem).
You can use your phone to interact with the lights (no app required, it's a Wi-Fi access point). It defaults to a red-green-blue-white pattern at power-up. The silver button in the lower-right allows two user-defined actions in WLED without needing to involve your phone. And it's an xLights receiver, too.
It also serves as a bench power supply for any voltage up to 36V and 6A. You feed it one power source, it will adapt to any voltage that you need.
You can plug it into the wall (AC input) or strap-on a power bank via USB-C to make it portable! The case is 3D printed (of course).
I've been wanting something like this for years.
