wpwrak(ehsm location) you mean the pictures in the middle ? "the caverns of DESY" has a nice ring to it ;-)09:11
larscwas the ring joke on purpose?09:16
wpwraki noticed the lovely pun while writing it ;-)09:17
lekerneltoday's weird experiment: cleaning solder flux with liquid butane/propane. it actually works :)10:30
lekerneland I assembled EDID on 2 other HDMI boards - all channels work correctly. so it's probably poor contact/solder or something like that on the board that has the transceivers... just bad luck :(10:39
mumptailigther gas?11:22
Fallenougood news, the fpga design is good :)11:42
FallenouAlarm told me he will soon assemble the hdmi boards11:43
Fallenouthen we will meet so that I can get one11:43
lekernelFallenou, which fpga design?12:02
lekernelmmu?12:04
lekernelmumptai, misused duster spray, but I think lighter gas would work just as well12:05
mumptai;)12:05
lekernelwpwrak, the conference room is part of desy12:05
Fallenou14:02 < lekernel> Fallenou, which fpga design? < the hdmi design12:12
lekernelwell, yes, EDID no longer has pesky bugs12:14
lekernelthe data part, however, ...12:14
Fallenouand as soon as you send data, does it make other parts of the design fail like before ?12:16
lekernelno, this is fixed too12:16
Fallenounice :)12:16
lekernelbut the data reception and/or decoding does not work12:16
wpwraklekernel: (EDID working) great !13:28
wpwraklekernel: what kind of flux do you use ? RA ?13:29
lekernel"no clean" (but still leaves ugly residues) rosin13:37

lekernelthe residue "resembles diluted bird-droppings" (wikipedia)13:42
wpwrakfunny description ;-)14:17
wpwraki use an ultrasound cleaner, with demineralized water (the kind you use in cars, so it's easy find). no risk of aggressive solvents.14:18
wpwrakthere's a risk that it could hit a resonant frequency and destroy something, but so far, i had no problems of that kind. there are also more expensive models that vary the frequency to avoid just that sort of issues.14:19
wpwrakthat's for "no clean" or "water soluble", and it can also handle small amounts of RA. for lots of RA, you may still need solvents, though. but then, "lots of RA" is dirty work anyway :)14:23
