Okay, so lets say you need to get a specific voltage from the mains, but you don't want it to be DC, or need it as a Step up transformer. You could either go to radioshack, and spend a few dollars on some really cheap transformers, or you could go my way....
Transformer -- --
1. An electronic device used to transfer electrical energy from one circuit to another through magnetic energy, or the transformer's coils.
2. A autonomous robot that can change form from any everyday mechanical object to a full sized robot.
Now as cool as it would be to have your own Decepticon killing robot, I'm talking about a different type of transformer. One that's not as near as great but still pretty cool. You'll get a 60 hz iron core transformer from this instructable, usable as a step up or step down transformer.
Step 1Where does one get a transformer, Jared?

Simple, grab one of those wall adapters that you use for everyday devices! HOWEVER, don't use the kind that feel unusually lightweight compared to the amperage rating. I smashed a 5 amp dell charger, which was remarkably light. I only got a small ferrite core transformer and some various odds and ends of parts from inside it. Nice 400 volt cap inside it though. :D ANYWAY, I got mine from ...some type of thing, I'm not even entirely sure what it was used for. It doesn't matter what rating they're for, however, i like to find bigger ones as they can handle more current.
I especially like the method of extracting the internals :)
