<garit> so i guess vacuum tubes, wires-in-flame transistor, mechanical relay, tunnel diode from aluminium piece and zink covered diode, and probably crystal-and-needle transistor from some gallium material - are the only non linear devices with setup cost below 10k usd?
<garit> zink covered wire*

<SpeedEvil> CDS cell in principle
<SpeedEvil> sparkbangbuzz
<SpeedEvil> see cds cell FET
<SpeedEvil> Also, you can certainly do transistors (si) of poor yield, signal at that
<garit> sparkbangbuzz with cds - why did he use tape instead of making thin film of plastic (drying the solution of PS in xylene or sodium silicate in water)? tape seems way too thick for this application (gate isoator)

<garit> wow, table salt can be used as a window for CO2 laser!
<SpeedEvil> they're now giving away CO2 LASERS with free boxes of crap engraver today.
