New in the Maker Shed - Plug-in Bread-Board Power Supply

Mkci1-2

Bring power to your prototypes with this convenient new kit -

This power supply module plugs straight into common bread boards, allowing you to cleanly and easily power your board with a wall wart plug or with wires into screw terminals. It features a variable voltage regulator that can be set to output 3.3 or 5V with a jumper, or any voltage if a potentiometer is added. The input has a rectifier that accepts AC or DC (polarity doesn't matter)--just make sure the input is about 2V greater than the output you want.
An easy way to enable those red and blue lines we so often jumper into usefulness - Plug-in Bread-Board Power Supply

Why?

The plug in bread board power supply seems like overkill to me. C'mon, really, any wall wart will do, and you don't have the PS getting in your way when you're creating. Also, you can find wall warts by the hundreds in just about any voltage and amperage-- people tend to throw them away when the item they power breaks. I must have a couple of dozen in a drawer in my desk at home. It just doesn't make sense unless you can't seem to do anything unless its form fitted for you.

Re:Why

Microcontrollers and logic need a regulated 5v or 3.3v supply which a wall wart cannot give. I built one of these for myself and it's an extremely handy tool, enabling you to use wall warts for prototypes and circuits where you normally couldn't use them.

Re:Re:Why

Wall warts may or may not be regulated. Regardless, there's a lot of noise on breadboards.

wow

Wow, that's really nice. This is actually a useful gadget that is more than adding an LED to something. Cool stuff and keep up the good work.

It's cute.

What I do is use a regulated wall wart (I got a bunch of switching 5V 2A wall warts for $2 eacha while back). And as for noise on the breadboard, I have a couple of 0.1uF caps along each power rail.

For what this little board costs, if I really needed a breadboard PS I'd get something like an iDuino (about the same price), and have it pull double duty just plugging the PS output pins into the breadboard power rail and using the other end of the breadboard.
