We are building a small exhibit on the basics of electricity and maybe
some electronics.  I have some old specs for a power supply but would
love to hear the suggestions of others.  I'm loking for something in the
5-12 VDC range, maybe both fixed and variable outputs.  And what about
limited amperage? My old notes and some stuff I have been reading
suggests 1.2 amps.  The other question is short circuit protection? I
see units available with it built in.  Is this a simple circuit to build
and add? Can I do the same for battery packs?
