I’m finally getting some decent results producing 100%-edible iridescent tempered chocolate. The colors are from the chocolate (not any ingredient or coating) diffracting light after being forcefully molded onto a diffraction grating in vacuum.

@Vap0rz Copper evap was done at 8e-5 torr, ran variac for 30 seconds at full power through a reversed microwave oven transformer with 2 turns of welding wire as the secondary (there was still some unevap’d Cu). Took 2 hours to get chamber to that level (it’s a janky+dirty setup atm)

@Spirit532_ Thanks, makes sense. This is what I’ve been using for all projects so generalizing it for various things but may try to make it an evap/sputter chamber only but limited in metal&pumps. Chamber’s small so hard to expand the inlet much more, ISO100 valve en route for CF chamber tho

@Spirit532_ I’m making a polycarbonate shell for it but I don’t operate it with line of sight to me anymore (brought the variac/controls close for pic). By pre-evac you mean no need for the high vacuum valve between the chamber and turbomolecular pump?

@kcimc I think gas chromatography-mass spectrometry would be ideal and is reasonably priced, eg $44/sample here

Yup. The slipstream page describes how to inject arbitrary UDP packets from the browser via TURN's authentication mechanism as an individual packet though I haven't tested that mechanism since release, search "TURN" @ (there are likely other ways too)
while reading @evilsocket's cups-browsed i was immediately reminded of @samykamkar's so... can TURN protocol be used to generate an arbitary UDP packet from the browser? (i'd normally check myself, but have zero time lately)

@risknc I’m using the scope purely as a sig gen here :/ input goes through some amps/RF gear and into SDR/computer for processing
