I decided to make a quick video of me soldering together the Plug-in Bread-Board Power Supply from the Maker Shed. This power supply makes a great addition to anyone’s electronics lab. Here’s why:

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. Skill level: beginner.

    nice iron!

    (want, want)

  • RDAC

    Maybe I’m nuts, but if I wanted quick 5V power, why not pull it off a USB cable? Simple, universal, and done?

    I tried once powering a uC based little circuit from the USB but there wasn’t enough current.
