Patching out an instrument for easy experimentation is a great idea – but drilling an array of holes and installing the appropriate hardware can be a bit of a hurdle to overcome. Experimentalists Anonymous points out this inventive use of a breadboard as a simple patchbay [scoll to bottom of page]. No need for banana plug or alligator clips, just trim some regular solid core jumper wire as patch cables. Wiring up the board should be pretty straightforward once you remove the breadboard’s backplate.
