Adjustable high current Lab SMPS out of a standard ATX PS
Krokenoster; I do not have one of these built, but am considering it after seeing this project. From the amateur radio side of my brain, if you installed ferrite beads on the wires just prior to where they connect with the external banana jacks that should resolve RFI on the line prior to feeding your instrument, toy, radio, etc.... You could also install some on the leads after you are out of the box leading to your appliance to ensure any surrious emmisions around the box are not transerfered as well. Just my thoughts with respect to RFI.
