Boxy, blocky, black power bricks with coaxial power plugs, they're everywhere!  Wouldn't it be nice to be able to connect wires to them in a non-permanent manner without any soldering or snipping required?  Recently I wanted to use a computer fan as a desk fan, and I happened to have a 12 volt power brick from some (likely long-ago trashed) computer speakers.  But I didn't want to cut or solder the wires because that means that I'd better be darn sure the computer speakers are toast, right?  So here is a non-destructive solution using only two paperclips bent with some needle-nose pliers I had lying around.  First, here's the finished product:

Step 1:

You'll need a pair of pliers or other bending device, a paperclip (a large sized paperclip was used for this example, but the smaller types may work just as well), and the plug you desire to attach leads to.
How powerful of a shock could you get from one of these if it slips n hits you?
Far far better to buy a suitable socket from radio shack (or maplin in the UK)
Paperclips are free and sometimes you just need the power to quickly test something. <br> <br>I would add a little bit of heat shrink or tape on the center lead. It is not dangerous but my experience with wall warts is, they will burn out if shorted. (probably internally fused)
Thank you, and that's a good idea too! Heat shrink tubing would be perfect, but even a little electrical tape would do just fine for temporary use.
