Not quite the same thing, but I remember an article in Sci. Amer. on
building your own electron microscope for home use. It would have been
around '78 - '80, probably some time in '79. The most difficult part
looked to be the glass tube which you would evacuate with some kind of
scavenged air compressor. I think they estimated the cost of the whole
apparatus at $200 - $300.
I tried to get our science club (in H.S. at the time) interested but
no-one believed you could really build the thing.
