hm, so, my hairdryer died on me yesterday (poor isolation + heat = catastrophic failure), so now I have some nichrome wire
<whitequark>
I want to make a heater for etching, but not sure what to use for the aggressive environment

so, I put it into a silicone rubber tube and sealed it with silicone
<whitequark>
my calculations suggest that at 40° outer temp and 100° inner temp (silicone rubber can surely withstand that), there would be about 300-350W of power transfer per meter of tube
<whitequark>
which should be plenty

grmbl. chromium seems to have learned how to crash the nouveau driver (and take the rest of the system with it). work-around: NoAccel True :-(
<wpwrak>
lovely scrolling in xchat now ...
<sb0>
just use the proprietary driver (-:C
<sb0>
and yeah, chromium doesn't play nice with buggy GPUs
<whitequark>
ooo, I just had an idea about exposing resist with film negatives
<whitequark>
specifically how to closely press the negatives to the PCB surface
<whitequark>
make a vacuum table!

sb0: with noaccel, chromium is actually pretty good. but all the rest sucks :(

whitequark, what about air bubbles trapped between the pcb and the film?
<whitequark>
sb0: since the film is not sticky--it's just a PET film for laser printer, not the photoresistive one--there will be no bubbles
<whitequark>
if direct laser imaging fails, that's what I will use
<whitequark>
that reminds me, I need some scrap printer

<eintopf>
everyone wants a atusb
<eintopf>
:D
<wpwrak>
a few do ... alas, not enough to motivate someone to make a production run, it seems

mhh. okay.
<eintopf>
wpwrak: now I have more motivation to improve the linux implementation
