**** BEGIN LOGGING AT Wed May 16 02:59:57 2007 May 16 07:29:55 okay May 16 07:30:15 I am not good at with messing with hardware and will surely (I mean there is a 100% chance) mess it up May 16 07:30:24 but I really need this thing to be always power on May 16 07:30:43 the only way I saw was with a USB power suppply, but I don't have free ports May 16 07:31:02 is there any other way May 16 07:43:40 blaster8 May 16 07:43:48 yes May 16 07:44:19 do you know anything about powering the slug May 16 07:44:30 I'm wondering if this: http://cgi.ebay.com/CPS180PHV-CyberPower-PhoneSaver-180-UPS-Surge-120V_W0QQitemZ250115994252QQihZ015QQcategoryZ16184QQrdZ1QQcmdZViewItem May 16 07:44:43 would supply power to my slug during a power outage May 16 07:44:58 * DrJ doesn't know a thing May 16 07:45:05 not even sure if my slug is DC May 16 07:45:17 all computers are DC May 16 07:45:31 but they need AC-DC converters to run on AC (naturally enough) May 16 07:45:55 so, going from the specs on that page May 16 07:45:58 would it work? May 16 07:45:59 traditional UPS take AC, convert it to DC to charge a battery, then convert that to AC again when the power goes off May 16 07:46:15 hmm NSLU2 needs 5V May 16 07:46:27 it says it provides up to 12V May 16 07:46:30 over DC May 16 07:46:46 it's a neat idea May 16 07:46:55 so it will work? May 16 07:47:04 I'm not going to risk the hardware methods May 16 07:47:07 NSLU2 needs 5V however, and it only provides 6V minimum May 16 07:47:11 I'm guarenteed to mess it up May 16 07:47:23 so it would need hardware modification or an extra voltage regulator May 16 07:47:24 I just want always power on May 16 07:47:29 and this will get me through most power failers May 16 07:47:31 if not all May 16 07:47:48 DrJ: as I say, it's a neat idea, but doesn't give quite the right voltage May 16 07:47:58 okay May 16 07:47:59 not a terribly difficult fix but you need some technical expertise May 16 07:48:22 so supplying 6V to it would fry it I take May 16 07:48:50 I wouldn't want to May 16 07:49:15 it may work, but it may also do nasty things to downstream USB devices May 16 07:49:37 I'm not sure what the onboard NSLU2 power circuitry is like May 16 07:50:50 well, I just bought one May 16 07:50:53 found another one for $12 May 16 07:51:00 that includes shipping, and new May 16 07:51:04 so I'm going to attempt this May 16 07:52:00 maybe I will find someone who knows if supplying 6 volts will damage it May 16 07:52:03 however May 16 07:52:08 you said a voltage regulator May 16 07:52:22 * DrJ does a search for one May 16 07:53:39 eh May 16 07:53:43 from the resulst I'm getting May 16 07:53:45 DrJ: I mean building a circuit with a cheap linear voltage regulator and putting it in series May 16 07:53:46 that involves hardware May 16 07:54:11 [03:53:48:am] DrJ: I mean building a circuit with a cheap linear voltage regulator and putting it in series May 16 07:54:16 no clue what you just said May 16 07:54:25 that may be the problem May 16 07:54:25 only thing I know about power is it can kill you May 16 07:54:31 and oddly enough, bring you back to life May 16 07:55:10 but I know 6V isn't much more than 5V May 16 07:55:27 this thing though, if I can get it to work May 16 07:55:34 should provide more than 2 hours of life for the slug May 16 07:55:40 on a full charge May 16 07:55:43 6v is much more than 5v in this case... May 16 07:57:13 DrJ: remind us of your application please, you want a batterypowered slug? May 16 07:57:16 maybe I can find a premade 5 Volt regulator? May 16 07:57:46 DrJ: they come in bulk yes, but requires soldering ;-) May 16 07:57:46 no, I want it stay running during a power failer May 16 07:58:17 DrJ: aha, and then a normal UPS in which you plug your normal psu should do it May 16 07:58:19 DC is not designed for the end-user May 16 07:58:26 I'm looking for cheap cheap May 16 07:58:42 in that case, you need to be a competent hardware engineer May 16 07:59:58 DrJ: you could by your phonesaver and a cheap car adapter that provides 5V from 12V May 16 08:00:26 hmm May 16 08:00:28 * DrJ searches May 16 08:00:35 I already bought that phonesaver thing May 16 08:00:39 found one for $10 May 16 08:00:44 well May 16 08:00:46 $12 May 16 08:01:24 hmm May 16 08:01:28 how would that work oddbjoh? May 16 08:01:31 oddbjoh: the issue is that is would have to supply 2A of 5V May 16 08:01:36 which is quite a bit May 16 08:01:44 blaster8: yes, that is correct May 16 08:02:42 hence the preferred solution is to get a UPS and plug the normal psu in, but 12v - 5v should be avail as quite a lot of people need 5v 2A in their cars having only 12v available May 16 08:05:21 so I take it 6V will destroy the slug May 16 08:05:36 * DrJ could be bad May 16 08:05:41 go to walmart get one and try it on it May 16 08:05:45 then take it back May 16 08:05:57 DrJ: no, 6V is not good for the slug May 16 08:06:28 it is not 100% that it would burn instantly, but not worth the risk May 16 08:07:20 so I would have to regulate the output on the phone thing with one of those one things May 16 08:08:04 DrJ: yes, a 12 to 5v converter with the required specs would do it... May 16 08:08:35 could you point me to one? May 16 08:09:04 http://www.powerstream.com/dc6.htm May 16 08:09:19 first hit on google for 12v 5v converter May 16 08:09:30 yea May 16 08:09:36 but I don't see how that would work May 16 08:09:37 I mean May 16 08:09:41 what would I do with that round end May 16 08:09:46 that goes into the cig lighter May 16 08:10:04 solder on another plug May 16 08:10:16 oh May 16 08:10:19 snip that off May 16 08:10:33 DrJ: somehow connect it to your phonesaver May 16 08:10:36 and connect one like plugs into the phone thing? May 16 08:11:04 I have NO clue how that plug looks that needs to go in the phonesaver, but it should not be rocket science May 16 08:11:18 neither do I May 16 08:11:27 maybe I should just wait till this thing arrives May 16 08:11:56 * oddbjoh wanders off to do some work May 16 08:12:48 too bad this thing does not supply 5V May 16 08:15:24 I guess I always my dad May 16 08:15:28 he does understand this stuff May 16 12:25:00 oddbjoh May 16 12:25:12 it looks like all these car convertors only do 4.5 May 16 12:25:14 Volts May 16 12:25:15 not 5 May 16 12:25:19 will that be a problem May 16 12:28:03 * DrJ is going to find a way to make this thing work May 16 12:29:16 I need to learn about eletrical crap May 16 12:29:23 at least the basics May 16 12:32:50 too bad this thing doesn't have an AC connector May 16 12:36:08 * DrJ could take the unit to his college May 16 12:36:32 I know a prof in the electronics department who would do it for me May 16 12:36:34 didn't think of that May 16 19:29:34 anyone know why slugosbe-4.4-beta won't boot off the disk even after i turnup disk it? May 16 20:32:06 no matter what i do it won't use the disk... May 16 20:49:47 :P May 16 20:51:28 do you happen to know why turnup disk -i -f /dev/sda1 would not make it use the disk? May 16 20:51:44 it makes the root file system and all that just fine but it's never using it... May 16 20:53:50 well May 16 20:53:58 I'm really a n00b but I know unix May 16 20:54:03 I got my slug last friday :) May 16 20:54:05 ah May 16 20:54:06 nice May 16 20:54:16 thanks for responding at least :P May 16 20:54:18 but I'm using openslug and I used "turnup memstick -i ... May 16 20:54:35 well, let's see what we can do May 16 20:54:46 * xkr47 logs in to his slug May 16 20:54:49 hehe May 16 20:55:01 i need disk since i'm using a hard drive May 16 20:55:06 yeah May 16 20:55:20 the weird thing is that it used to work May 16 20:55:27 just fine May 16 20:55:30 with older openslug ? May 16 20:55:32 and then i updated May 16 20:55:34 yeah slightly older May 16 20:55:37 both are 4.4-beta May 16 20:55:46 hmm.. can you possibly send the turnup script to somewhere ? May 16 20:55:56 email / pastebin / dcc / www May 16 20:56:00 sure May 16 20:56:12 I can compare it to mine (I have an older version) and see if there's something fishy May 16 20:58:10 http://www.cs.virginia.edu/~smt6k/turnup May 16 20:58:14 thanks :) May 16 21:00:37 * xkr47 \ | / - \ | / - May 16 21:01:04 do you get any errors when you do it May 16 21:01:17 yeah actually May 16 21:01:24 "read-only file system" ? May 16 21:01:35 * xitrium checks May 16 21:01:48 do it -> run turnup May 16 21:04:07 http://paste.ubuntu-nl.org/21192/ May 16 21:04:45 it writes to disk so it can't be ro... May 16 21:05:44 are our turnups the same? May 16 21:06:14 there was one -oremount,rw that had been removed May 16 21:06:54 ah May 16 21:06:54 huh May 16 21:07:13 ok.. it seems those errors come from "makedevs" script May 16 21:07:47 and that seems to be a binary :) May 16 21:07:56 haha May 16 21:07:59 well... May 16 21:08:02 do you have some custom kernel May 16 21:08:05 yeah May 16 21:08:15 maybe you got the udev settings wrong somehow May 16 21:08:21 hm May 16 21:08:23 or it requires a newer udevd May 16 21:08:25 or older May 16 21:08:26 :) May 16 21:08:57 i think that there's something deeper wrong, because it never even tries to boot the disk May 16 21:08:58 don't know if that can cause the failure to change the boot device tho May 16 21:09:04 yeah May 16 21:09:08 if it had, there's supposed to be a .recovery file or something according to the wiki... May 16 21:09:11 yeah... May 16 21:10:51 I'm sorry, I think I am of no help for that May 16 21:11:01 I don't understand enough of the boot process yet May 16 21:11:03 yeah May 16 21:11:04 me either May 16 21:11:06 thanks for trying though May 16 21:11:16 what are you using your slug for, if I may ask :) May 16 21:11:37 to model an active disk for some research May 16 21:11:55 my plan is to create an mp3-playing alarm clock :) May 16 21:11:59 haha, sweet May 16 21:12:11 how will you get sound out though? May 16 21:12:21 I was thinking of getting some usb sound card May 16 21:12:29 the wiki was mentioning some that worked May 16 21:12:32 ahh May 16 21:12:40 that's pretty cool May 16 21:12:47 there's a lot of cool stuff you can do with these May 16 21:13:08 another way could be if the internal beeper is a regular pc speaker.. one could replace the little squeaker with a good loudspeaker :) May 16 21:13:25 hehe May 16 21:13:28 yeah, these slugs are so small you want to build small equipment everywhere :) May 16 21:13:29 that would be cool May 16 21:13:32 haha, yeah May 16 21:20:25 xitrium, you have tried the turnup on a new disk? May 16 21:20:45 * xkr47 thinks -i should flush anything that was there before, right ? May 16 21:22:30 dunno, myself don't use openslug, but it seems, that there are problems with the turnup process, you have at least two partitions, one for the system and one swap, and the "system" partition is mounted well, before running the turnup command? May 16 21:59:54 caplink811-log, i haven't tried it with a brand new disk, but i have tried completely reformatting and repartitioning this disk, but to no avail May 16 22:00:28 i don't have a swap May 16 22:00:30 is that necessary? May 16 22:00:50 well, that should be enough, the system partion is mounted well before running the turnup command? May 16 22:01:07 mounted well? May 16 22:01:11 is that the same as mounted May 16 22:01:12 ? May 16 22:01:43 sure, mounted read/write May 16 22:05:04 i'll try... i think i did but i'm not sure May 16 22:08:59 yeah, i tried it May 16 22:09:08 and when it reboots /dev/sda1 is still mounted as /media/sda1 May 16 22:10:03 any ideas...? May 16 22:14:05 maybe that is a good idea, to mount your /dev/sda1 to /mnt May 16 22:30:10 but i want it to use that as / May 16 23:07:58 can anyone plase help me with some asterisk config questions May 16 23:22:27 i've never used asterisk, sorry **** ENDING LOGGING AT Thu May 17 02:59:57 2007
