Our friend Daniel Garcia from Proto Stack has come up with a bunch of Breadboard Tips and Tricks that could make your life a bit easier next time you are breadboarding a project. The one shown here is a nice tip where you use pin headers to allow the use of multi pin devices that could otherwise never be connected to a breadboard. I do the same thing with some common value pots and small relays. There is another tip that will probably save you a few hours over the years and a few grey hairs. That is a way to solve the center disconnected positive and negative rails.
