Hadn't thought of doing that. I guess I could post a proper schematic. There were really only two tricky parts to it... Making sure the banana jacks were the correct distance and square so that I could "bridge" any two (except diagonally) with a dual banana plug. And... cutting that damn C cell battery connector and mounting it.
I suppose a parts list with costs would be useful. Most everything is stock rat shack parts, except for the PVC sleeve and the connector for the atty.
Maybe soon....
I should also post a how to on using a standard AT type computer power supply for a 5V source. But I think someone has done that already.... Gee, how do you search with 5V as a search term? The forum system says its too short.
