RSSBreadboard power supply hits both rails
Chris writes -
David Fowler at uCHobby has introduced his new-and-improved breadboard power supply, which is both an excellent introduction to soldering technique *and* a useful tool for further electronics work.Indeed it is a nice little board - with additional header pins to bring power out to both sides of the board and add some extra stability. Jumper selectable 3.3/5V operation, plus one feature I don't see often enough on supplies like this - a power switch. It seems one should consider adding a heatsink to that voltage regulator if you plan on using an input source higher than 25V - SBBPWR2 Revised design for Breadboard power supply module

Inspired by this and other breadboard power supplys, I designed my own with positive and negative output, meant to use with op-amps.

What a neat design! Wish I'd thought of it...
BTW, a power switch that's very easy to operate is vital in a gadget like this -- you may need to switch off in a hurry if things are getting hot on the breadboard!

Cool idea! Though I'd rather have a switching regulator and SMD soldering practice myself.
