A simple project, but a useful one.
I’ve found the need for a 12V barrel splitter for a series of pumps and lights in an automated fish tank water change project. I built a basic board that takes a fused 12V barrel plug and simply splits off to 4 other ports, nothing special!
A Little 3D Printing Adds a Nice Touch
Future Upgrade Ideas:
Future improvements; or complexity, depending on how you look at it: Could include adding a micro-controller, high-side current monitors and a 0.96″ OLED to display power consumption on each channel. Individually fused outputs can also be used to allow one channel to fail completely, without cutting out power to the other ports.
