My old breadboard was starting to get a little tired so I thought it was time to update it and to something more useable. The old one was homebrew more or less, but how it was being powered was becoming a nightmare to use.So i grabbed one of these of ebay, and with a breadboard power module i have 12v 5v and 3.3v as well as USB power out. All in all this will be much more usable than the old board.
