Electronics surplus is: * Used industrial, medical, military, or scientific equipment * Electronic components (often those that were purchased for a product or project but never used) * Electronic test equipment (usually used, sold as-is, and priced well below retail) * Excess inventory - components, hardware, assemblies, sub-assemblies, etc. * Miscellaneous odds and ends that might be fun to take apart or re-purp… text/html 2011-10-22T13:47:36-05:00 http://mightyohm.com/wiki/resources:swtools?rev=1319309256&do=diff Circuit Simulation * LTSpice/SwitcherCAD, Great, free circuit simulation tool * MacSpice - Spice on the Mac <http://www.macspice.com/> PCB Layout / Schematic Capture * Eagle - <http://cadsoft.de/> * Very good cross platform support.
