**** BEGIN LOGGING AT Tue Jan 28 02:59:59 2014 Jan 28 03:00:08 My thought is perhaps heating the entire board up to say 120F, slowly... let it sit there for a while, then shield the chips around it and just hot-air-melt it Jan 28 03:00:16 sure heating up the whole thing to ~80°C before you start will help a lot Jan 28 03:01:20 hot air is fine for the tiny electrical contacts, but for the huge groundplane stuff you want a old fashion monster iron Jan 28 03:01:41 I may have to grind myself a custom tip... my thin one couldn't get enough heat to it Jan 28 03:01:48 see if I can come up with something Jan 28 03:01:52 yes Jan 28 03:03:53 I'd use that one if I still had it: http://www.lidl.de/de/Loetwerkzeuge/PARKSIDE-Loetpistole-PLP-100-A1 Jan 28 03:04:06 ideal tip shape, ideal power Jan 28 03:04:21 Or, maby I'll just get a NeoN900 Jan 28 03:04:25 board for it Jan 28 03:35:14 good plan :-) Jan 28 04:07:57 anyone have issues with mumble not working? installing in app manager gives a dep failure because it wants like 1.2.4 when the repo has 1.2.6 Jan 28 04:08:58 and if you decide to be naughty and just install it with apt-get, it fails to actually pick up anything audio related. It sees all the devices and everything fine but there's o output or input (presumably the mumble-11x package does something to fix this) Jan 28 04:48:31 Is the RX-51 the hardware part of the N900? (reading about the Neo900) Jan 28 04:51:45 Yeah Jan 28 04:51:53 RX-51 is the model Jan 28 04:58:16 wow, there are quite a few challenges to making the Neo900 a reality. Jan 28 04:58:48 (just finished reading the "feasibility study"). I hope we find a big enough market for it. Jan 28 05:06:48 kwtm2: link? Jan 28 05:09:10 Tekk_: http://projects.goldelico.com/p/neo900/downloads/get/neo900-feasibility.pdf Jan 28 05:09:19 Tekk_: That's from http://neo900.org/specs Jan 28 05:10:13 yeah, found it on the site Jan 28 05:12:44 hm, noticed an nfc in the best case specs. does that mean other half like functionality in that case? Jan 28 11:58:52 that's up to you to switch your profile or wallpaper or theme when NFC detects a certain tag Jan 28 12:45:36 DocScrutinizer05: ooh, how will the neo900 support battery hotswap? Jan 28 12:47:49 will that also mean that we can have pure-hardware battery charging? Jan 28 12:59:58 kerio: that's pretty much unrelated Jan 28 13:00:19 mh, fair enough Jan 28 13:02:17 hotswap basically works like: connect all dispensable consumers directly to battery, buffer the rest from a huge buffer capacitor that we charge to a multiple of needed voltage and use as some sort of UPS Jan 28 13:03:31 e.g. modem has 3 power supply pins, of which one is low-power and can keep the modem alive for a few secons from a pretty small buffer cap Jan 28 13:03:43 i see Jan 28 13:03:49 that's neat Jan 28 13:03:57 so you'll still have to be quick with the hotswap Jan 28 13:04:00 of course TX will fail and modem needs to resume after that Jan 28 13:04:06 yes Jan 28 13:04:31 that's the point about "ultrafast batteryswap procedure" Jan 28 13:07:28 http://www.youtube.com/watch?v=1ta7Mh9a_y8 Jan 28 13:10:32 the charging is planned to be exactly like TI reference in e.g. beagleboard, i.e. based on twl4030. Evaluation pending, we don't want to run into a true deadlock where device can't charge when battery deep discharged Jan 28 13:10:53 in GTA04 it allegedly works flawlessly Jan 28 13:11:47 I'm still not happy with the GTA04 circuitry since it uses a linear regulator which has a pretty poor efficiency Jan 28 13:11:47 like the n900 ahem ahema Jan 28 13:12:44 what's wrong with Neo900? it charges from almost all situations except broken rootfs and already defect EOL battery Jan 28 13:13:14 s/Neo9/N9/ Jan 28 13:13:14 DocScrutinizer05 meant: what's wrong with N900? it charges from almost all situations except broken rootfs and already defect EOL battery Jan 28 13:14:44 it's a tad unfortunate that you will discharge your battery by bootlooping when rootfs broken, and you can't restore rootfs via simple normal flashing when battery is too low Jan 28 13:16:12 you can recover even from that with rescueOS and similar RAM-based charger software Jan 28 13:18:17 Neo900 might not support classical flashing at all, and instead boot from uSD, so even less of a recovery hassle even when your NAND based rootfs is broken. You simply insert a uSD that has a sane working rootfs and you're good to go for charging and for flashing NAND Jan 28 14:10:37 script: read backscroll^^ Jan 28 14:20:53 ??? Jan 28 14:21:12 script didn't say anything the last few days, it seems Jan 28 14:25:22 chem|st: I'm not able to join meeting tonight Jan 28 14:38:01 DocScrutinizer05: noted Jan 28 14:38:41 I am talking with him in another channel about neo900 Jan 28 16:34:22 huh? where is the crontab? Jan 28 16:37:38 Have you installed a cron daemon? Jan 28 16:42:20 do you have to? Jan 28 16:42:31 I cant find any.. Jan 28 18:28:31 well, opened up the n900 with broken usb and the port was just loose there, took a couple of pics http://joga.daug.net/n900-usb/ Jan 28 18:29:07 (of pads on pcb and the connector itself) Jan 28 18:29:39 I guess I at least need to get a spare port, only seem to have spare miniusbs now Jan 28 18:31:03 also need to get some compressed air... Jan 28 19:11:06 SAiF: alarmed might just have all you need.. unless you have 'special' need Jan 28 19:11:47 right, since there is no cron on maemo Jan 28 19:12:06 alarmd is as close as it gets to crond Jan 28 19:13:22 and you could use alarmclient to manage alarmd "crontabs", but you don't want to go that bumpy road. Rather use alarmed Jan 28 19:14:12 (somebody should port alarmed to default PC linux, as a decent frontend to cron) Jan 28 19:15:46 joga: why? all looks pretty "easy", just solder port to PCB again Jan 28 19:16:06 looks like you were extremely "lucky" with your usb breakage Jan 28 19:16:17 yeah considering the pads are ok Jan 28 19:16:28 it just looks a bit filthy but haven't cleaned it up really yet Jan 28 19:16:39 that's the point Jan 28 19:17:05 first of all you need to clean port and PCB pads with solder iron and solder wick Jan 28 19:17:22 then go for: Jan 28 19:17:23 yeah, got those Jan 28 19:17:25 ~usbfix Jan 28 19:17:25 usbfix is probably http://talk.maemo.org/showthread.php?t=75920 - and **NEVER** use epoxy (unless you want to seal your device for underwater) Jan 28 19:17:50 ye, glanced at that, I guess I'll do the scrape thing Jan 28 19:18:15 after I get over this flu I'll try Jan 28 19:18:16 you can remove/cut/bend the "roof" over contacts of port, to better reach them Jan 28 19:19:09 nevermind, not really Jan 28 19:19:48 the spot looked a bit tight but I guess others have managed to do it nevertheless :) Jan 28 19:19:50 the mech fix pads *under* the port are dead, bit that's not relevant Jan 28 19:20:08 yeah, hot air might help Jan 28 19:22:00 anyway just make sure you wetted pads and contacts properly with solder, and applied SMD(!)-flux to both. Then place USB in correct location and fix (sticky tape or tiny solder blob on one side) Jan 28 19:22:40 then either hot air or iron with thin tip, and just heat up the 5 contacts Jan 28 19:23:05 then fix port thoroughly according to ~usbfix Jan 28 19:24:38 DocScrutinizer05, thanks Jan 28 19:24:40 if nothing of all that works for you - use 10mm thin wires to connect port to pads. Bend wires up to form inverted U while pushing port back into correct location, before fixing it on both sides Jan 28 19:25:43 this is a botch, but should work "good enough" Jan 28 19:25:53 yeah Jan 28 19:26:02 if soldering the 5 contacts turns out to be too hard Jan 28 19:26:37 wires must not be longer than 10mm Jan 28 19:26:37 I don't have a hot air gun and just some basic flux pen but I think I can manage one way or another Jan 28 19:35:08 I guess I can just barely reach back there with the finest tip I got... besides the flex cable and some plastic beside it, are there any extra sensitive components near there I might screw up if I heat it too long? Jan 28 19:35:25 the tip is pretty crap heat transfer wise Jan 28 19:35:27 :) Jan 28 19:42:13 lift off the uSD daughterboard Jan 28 19:42:29 protect camera! Jan 28 19:42:47 then you're basicaly fine Jan 28 19:43:26 take care of the flex cable though, it's not really easily damanged but non-recoverable if you damage it Jan 28 19:44:20 it won't break when you take care a bit about it Jan 28 19:47:30 ooooh it lifts off eh, didn't realize to try but figures Jan 28 19:53:46 scared to lift it though...should it just pop out if done right? Jan 28 19:54:43 the service manual just mentions how to get the camera out but didn't find proper procedure for the uSD Jan 28 19:57:51 i cut away the shield next to the usb connector when trying to solder it... Jan 28 20:05:37 r00t|home, did you succeed? Jan 28 20:12:08 ok this picture is useful... http://people.openmoko.org/joerg/n900/images/n900_12.jpeg Jan 28 20:13:03 now to figure out how to achieve that without screwing up the flex.. Jan 28 20:20:55 ah, got it Jan 28 22:12:35 r00t|home, did you succeed? <---- no Jan 28 22:13:09 joga: i ripped out two or three of the five solder pads... Jan 28 22:13:14 :( Jan 28 22:13:28 I've a much luckier situation fortunately Jan 28 22:13:33 joga: an attempt at using the usb on the debug pads also didn't work **** ENDING LOGGING AT Wed Jan 29 02:59:58 2014
