Goldmine just got in a handy little transformer at a somewhat reasonable price. I immediately saw it as an ideal building block for a small benchtop power supply that many beginning exerimenters could use.
As if I really need any more supplies around here I'm probably going to build one anyway with the idea of shooting for the best compromise of size vs. incorporated functionality.
Let's see how the various members would go about putting something together, trying to keep the costs minimal yet still using commonly available parts most anyone could esily come up with.

I'm easily seeing a +/- supply for op amp usage and a switch that would allow the windings to be used in series for a single but higher voltage capable supply.
This is just a basic practice exercise for most of the beginners that, in the end, could benefit a lot of people that were just starting out.
