Ceramic capacitor voltage sensitivity.

I looked up a Samsung 1206 22uF 25V X5R capacitor on their website.

Huge variation in capacitance against voltage. At the rated voltage the capacitance goes down by 90%.

Way more than I ever imagined! Would make a good VCO!

How #chemists turned #bourbon waste into #supercapacitors
Hydrothermal carbonization can directly convert #stillage into hard or #ActivatedCarbon. Cossio & Guzman used activated carbon as #electrodes, creating double-layer #capacitors by putting liquid electrolyte between them. Proof-of-concept devices were able to store as much as 48W/kg. Built a hybrid device, with one activated carbon electrode and one hard carbon electrode, stored as much as 25 times the energy per kg

I can finally check that this old Frako is just fine!

Oddly consistent corrosion: every 16-volt electrolytic in the device, plus one 25-volt. All the others were fine (after about 44 years). Or alternatively, all but one of this brand. There doesn't seem to be corrosion anywhere else, so it's probably not flux residues; but would all these have leaked or is it something to do with the metal itself?

Anyway, this is just tidying visible problems; don't know what's functionally wrong yet.
