Our friend Quinn Dunki has a benchtop power supply, but she wasn’t entirely satisfied with it. Quinn has needs. She made a list:

Quick on/off switch for the board, separate from the bench supply
Indicator light for when the breadboard is hot
Switchable between unregulated supply and regulated 5V
A place to patch in an ammeter for measuring the draw of the entire circuit
A bunch of reference ground pins for scopes, meters, etc.
Supply to both sides of the breadboard

She got to work and the “Juice Bridge” was born. See her site, Blondihacks, for the full details and schematics (and some discussion about improvements/additions).

Ah, this was featured on hackaday recently. Hugely impressed by Quinn Dunki’s work, and she was gracefull enough on HaD to point out that some things, like the big switch, aren’t really needed at all and would be changed for a V.2

I just paíd $20.87 for an íPad 2.64GB and my boyfriend loves his Panasoníc Lumíx GF 1 Cámera that we got for $38.79 there arriving tomorrow by UP S.I will never pay such expensive retail príces in stores again. Especially when I also sold a 40 inch LCD T V to my boss for $657 which only cost me $62.81 to buy.
Here is the website we use to get it all from, BidsBit.com

I started a while ago doing things like this too:

It’s really handy to have the more “permanent” things adaptable to breadboarding without having to build them all over again every time on the breadboard itself. I think those ubiquitous boards with the red and blue lines should become standard.
