I recently acquired eight pieces of 210uF 700V rated metalized polypropylene caps.
I´d welcome some suggestions what I could do with them, I was thinking about some coin shrinking or similar, any good ideas?
Although, since 1,680μF (@700V) can only store about 400+ Joules, while not insignificant, its well below that needed for coin shrinking (from what I googled, in the neighborhood of 15,000J).
