Hackaday Prize Entry: SnapVCC

Hackaday Prize Entry: SnapVCC

While it’s the easiest way to lay out a simple circuit for prototyping, breadboards are a pain. They are the ultimate kludge; they work well enough, but no one will ever say that a solderless breadboard is the most elegant solution. [Mahesh] isn’t completely fixing the problems of solderless breadboards, but he has come up with a better way to supply power to breadboards. It’s a project called snapVCC , and it turns a 9 volt battery into a regulated 3.3 or 5 volt supply. The idea behind snapVCC is simple enough; just add a circuit board to the top of a nine volt and add a voltage regulator. [Mahesh] is using an LM317 adjustable regulator, with a switch to change the output voltage from 3.3 to 5 volts. An LED indicates the output active, and another switch disconnects the battery from the circuit. Yes, it’s very simple and very useful, confounding everyone who is wondering ...
