My dad used to really like trying to guess what was in his Christmas gifts. I remember one Christmas where as a joke I gave him an extremely heavy transformer from a [Bell UH-1 Iroquois helicopter|https://en.wikipedia.org/wiki/Bell_UH-1_Iroquois] that I'd bought at a local surplus store (I wanted the chassis it was in, or some such reason). I'd put his real gift under the transformer and there were some laughs, ha ha. He then picked up the transformer and dropped it into what he thought was an empty box full of wrapping paper, except it wasn't empty. It contained the Rotal Albert tea cup I'd just given my mom. Ugh. — [Murray]

A __[Switching Power Supply|https://en.wikipedia.org/wiki/Switched-mode_power_supply]__ (also called a "switched-mode power supply) doesn't use a big transformer. Most laptop power supplies are switching power supplies. If you're on one of the robot vendor web sites you'll see switching power supplies advertised. AdaFruit sells a 5 volt 10 amp for US$30, another one for $25. Most of these units have the benefit of being able to run from either 110 or 240 volts.

The only issue is that most of them don't end in a USB connector but rather a male DC plug; you'd have to convert that to a micro USB male, which is what's on most microcontrollers. Perhaps we need a [Recipe] on
