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 …read more http://hackaday.com
