wow. disrupt is even more of a terrible joke than I thought
<wpwrak>
"the startup Shipstr will make shipping from China easier" hmm, so they're a political party that wants to make an institutional reform ? ;-)
<whitequark>
just a bunch of hipsters whose arrogance far exceeds their competence
<wpwrak>
that's a rare combination :)
<whitequark>
well, you could say "yes" to your question, too
<whitequark>
wpwrak: any idea what to use to make a smooth DC sweep from 0V to 2kV (yes) in 100ms or so?
<whitequark>
I toyed with a voltage multiplier (Villard cascade) design, but it's too slow
<whitequark>
better description of signal I need: sawtooth with frequency 10Hz amplitude 2kV.
<whitequark>
also should be phase-locked to some external input
<wpwrak>
hmm, look for "sawtooth generator" ? or "function generator" in general ? there must be ton of old circuits for this. not sure what tricks they use.
<whitequark>
well, not for 2kV of amplitude :p
<wpwrak>
oh, didn't quite notice the 2 kV ...
<whitequark>
oh, and I want to use off-the-shelf components. something you could get at e.g. digikey
<whitequark>
specifically no custom transformers
<whitequark>
currently thinking of using a CCFL transformer--they go to about 1.3kV--and doubling it once
