I built and tested the 12V De-Slumpifier and it behaves very well with no surprises. I don't have a publishable test protocol, but for general purposes this is a good design that can be used for many anti-slump applications. If there is sufficient interest, I will make a PCB and maybe a kit of parts.

Note how much space remains inside the box. The 35W resistor and heatsink and one diode is under the perf board.

I added an optional LED indicator. The supercaps behave almost exactly like a 250,000 uF/20V capacitor bank which used to fit into a suitcase.
