Notes

Just a simple little project to clean up my desk a little, where I often have various power adapters and connectors cluttering up my space. This is an adapter that can plug into the power rails of a breadboard, and provides:

While I’m normally powering this from the barrel jack, it can actually be used to route power in with any of the connectors and out all the others.

The connectors and LED, with current limiting resistor good for up to 24V conservatively, are mounted on a small piece of protoboard, roughly laid out like this:

This page is a web-friendly rendering of my project notes shared in the LEAP GitHub repository.

LEAP is my personal collection of electronics projects, usually involving an Arduino or other microprocessor in one way or another. Some are full-blown projects, while many are trivial breadboard experiments, intended to learn and explore something interesting (IMHO!).

The projects are usually inspired by things found wild on the net, or ideas from the sources such as:

Feel free to borrow liberally, and if you spot any issues do let me know. See the individual projects for credits where due. There are even now a few projects contributed by others - send your own over in a pull request if you would also like to add to this collection.
