DocScrutinizer05whitequark: that would be me and paulfertser01:54
DocScrutinizer05alas I'm totally out of the loop with that. If you can do your own FOSS verification according to the rules stated on wiki, then pick a PID also according to the scheme there, drop me a note any I'll add it to wiki01:55
DocScrutinizer05given the wiki would work for once01:55
DocScrutinizer05seems the serbver is totally overloaded - it has only 32GB and 8 cores, evidently way too flimsy for a simple wiki and PLANET and CLAMAV and TRACK01:57

DocScrutinizer05ooh, and no arbitrary random PIDs please02:03
DocScrutinizer05no vanity PIDs02:03
DocScrutinizer05ooh, now I get it, this is about Qi, not about OM02:04
DocScrutinizer05thought you were talking about http://wiki.openmoko.org/wiki/USB_Product_IDs#Conditions02:09
DocScrutinizer05which is still dead, even with a load of only 0.2102:09
DocScrutinizer05whitequark: http://wklej.org/id/343136402:14
whitequarkDocScrutinizer05: I thought I was talking about OM too02:23
whitequarkbut wpwrak gave me a Qi PID and I mean that works too02:23
whitequarkit's not like I care which VID it is02:23
whitequarkI didn't even know Qi has a VID it gives away PIDs for...02:23
DocScrutinizer05well, now you are " Official Qi hardware products [which] have been assigned the following USB product IDs"02:23
DocScrutinizer05I'm not sure it may02:24
whitequarkdoesn't Werner own Qi or whatever remains of it?02:24
DocScrutinizer05iirc OM was pretty much the last VID that had a contratc that didn'T explicitly rule out such sharing02:24
whitequarkdoes Qi even exist as a legal entity anymore?02:25
whitequarkits VID cannot be reused anyway...02:25
DocScrutinizer05well, as long as you're an official Qi product, everything is fine per definition02:25
whitequarkha.02:25
wpwrak(own) naw, it's still all wolfgang's. i just have some slightly elevated powers here and there :)02:26
DocScrutinizer05I just wonder who's going to >>...help to keep this list in sync with the Linux USB ID Repository at http://www.linux-usb.org/usb-ids.html<<02:26
whitequarkI submitted my PID there myself02:26
whitequarkyou can add them via the web interface02:26
DocScrutinizer05yeah, at OM we do via email usually02:27
DocScrutinizer05web IH was fubar for quite a while02:27
DocScrutinizer05IF*02:27
whitequarkthey fixed it02:30
whitequarkthe email IF is broken though02:30
whitequarkI spent like ten attempts trying to send it a patch it'll like and then it folded over02:31
DocScrutinizer05omg02:41
wpwrakvictory ! finally got a LED to blink ! :)04:04
wpwrakwhat made that a bit tricky: 1) seems that USB bood apparently changes some reset default for GPIOs (or maybe they're different from what i found in the PMs) 2) the documentation says there are two user-controlled LEDs on the devkit but it's in fact only one (D4). toggling the GPIO where supposedly the other is understandably does nothing visible ...04:07
wpwrakand the usb boot protocol seems to diverge slightly from the jz4780: the cache flush command doesn't seem to be implemented, at least at the first stage. not that it would be needed anyway. (not even sure what it would do in stage 2)04:10
wpwrakand of course something like 5 seconds after the first successful test my usb connection failed :) not sure what's wrong. the board works fine with another cable on another port.04:17
wpwraksame cable works on another port. oh well. so many to choose from ...04:23
whitequarkwpwrak: DocScrutinizer05: so I made a vapor phase soldering machine06:41
whitequarkpretty much just a disassembled stew pot with a PID controller hanging on it06:41
whitequarkwonderfully simple process. turn on, wait a few minutes, turn off. (I should probably follow a profile, but this PID controller can't do it, so meh)06:42

DocScrutinizer05nice :-)12:04
wpwrakwhitequark: nice indeed !22:05
wpwraki wonder what makes galden so expensive. hard to produce ? fancy ingredients ? patents ?22:05
DocScrutinizer05I searched for other polyethers https://www.startpage.com/do/search?q=Perfluoropolyether and it seems at least there can't be a patent anymore after over 30 years of use of those substances in aeronautics. I found few actual products and they are usually very expensive22:50
DocScrutinizer05btw VPS reportedly was the very first mass production reflow process, before IR and hot air reflow were developed23:26
DocScrutinizer05I guess back when they used other more environment-hazardous heat transfer media23:27
DocScrutinizer05also see http://www.torenko.com/pdf/Todays-Vapor-Phase-Soldering-Tech-Paper.pdf "Abstract" first ยง23:30
DocScrutinizer05also " HISTORY OF VAPOR PHASE MACHINES"  >>The procedure was invented by Dr. Pfahl at Western Electric in 1974. Vapor Phase was widely used in the industry of the early Eighties.<<23:36
DocScrutinizer05same page23:36
DocScrutinizer05apropos patents: >>  Because of various patents on these new solder pastes, the lead free solder alloys were not creating one single new standard. Thus the use of different mixtures with different melting points became the situation of today.<<23:41
DocScrutinizer05btw wpwrak, what's your rating scale for "so expensive"?23:44
DocScrutinizer05ok, Galden is a 100 times more expensive than... gasoline. But for sure much cheaper than e.g. rose water23:46
DocScrutinizer05I'd guess production of that chemical is a tad tricky, given that Fluor is involved23:48
