The SwitchTrick came about because of a mistake - I was using this voltage converter on a different project and accidentally screwed up the pattern.  Before re-spinning that board, I decided to make a quick test board for the voltage converter and new pattern.  While doing that, it occurred to me that I could add a few features and turn it into a super handy breadboard supply....and then it became its own project and went through a few tweaks.  Now it's a nicely little packaged power supply, with cool colors that make it look like an extension of your breadboard, and lots of features for easy and flexible prototyping!
