Power bricks I have known and loved

Power bricks are the cockroaches of consumer electronics: they're ugly, simple and seem to survive everything. I've got a collection of power bricks for now dead or gone equipment that happily keep pumping out volts.

So, I figured that I would catalogue them to see what I had lying around.

I won't bore you with the complete catalogue, but the output voltages are interesting (these are the rated voltages, and not measured): 24.5, 24, 20, 20, 19, 12, 12, 12, 12, 9, 9, 8.4, 8, 6.5, 5.9, 5.1, 5, 5, 5, 5, 3.6.

I guess I don't need a fancy bench voltage generator regulator!

Actually, I find these quite useful at times. If you're at all handy with a soldering iron you'll be able to stick on an appropriate tip to suit whatever device has just decided to fry its wall-wart. I have to admit, though, you've got a very impressive range of voltages represented there.

Actually that's how I got into this little project. I wanted a power brick for a piece of battery powered kit that's at home which has a socket for 9V.

Got me wondering exactly what stuff I had lying around.
