| 00:36.14 | Tiersten | I've added a page on the IXP config registers now. Only cover reg 0 since reg 1 is software controlled |
| 00:37.02 | Tiersten | Squinting at my slug and the bare PCB pics on the wiki haven't been totally clear however and I don't know where 4 of them actually go. I know what they're set to, just don't know where they are |

| 01:09.14 | Tiersten | I think beewoolie is fairly safe about 110 |
| 01:09.38 | Tiersten | The documentation for the IXP465 has a slightly bigger table and it appears 1xx is always the highest speed |
| 01:09.59 | NAiL | Good. My slug is modded the same way. |
| 01:10.01 | Tiersten | There are gaps in our config register that are filled in by the tables in there as well for hardware we don't have |
| 01:10.17 | Tiersten | It's still not recommended anyway :) |
| 01:10.33 | NAiL | No, but mine was modded before we figgered that out :P |
| 01:10.36 | Tiersten | Just on off chance that there will be a NSLU2 with a C0 stepping IXP |
| 01:10.40 | Tiersten | 420 |
| 01:10.49 | Tiersten | on the off |
| 01:10.50 | NAiL | I'm getting another slug today, so I'm modding that the "good" way. |
| 01:10.53 | Tiersten | Not that there is a C0 anyway |
| 01:11.02 | Tiersten | How many do you have anyway?? |
| 01:11.32 | NAiL | I had two. One died of lightning. Now I'll be back at two. |
| 01:11.55 | Tiersten | ah |
| 01:13.25 | Tiersten | We've got two more combinations to test if somebody is willing :) |
| 01:13.33 | [g2] | Tiersten, are you building 465's ? :) |
| 01:13.45 | Tiersten | Nope. I just have the datasheets |
| 01:13.46 | rwhitby-web | died of lightning? |
| 01:13.53 | NAiL | yup |
| 01:14.12 | NAiL | It was scorched(sp?) |
| 01:14.18 | Tiersten | How? |
| 01:14.25 | Tiersten | Surge over the powerlines? |
| 01:14.33 | NAiL | yeah |
| 01:14.56 | NAiL | All my other stuff was behind my trusty UPS. So only the UPS blew. |
| 01:15.07 | Tiersten | Still ouch |
| 01:15.21 | Tiersten | We're up to 15 turboslugs which is pretty impressive considering it's only been a day |
| 01:15.36 | Tiersten | True, a lot of them are duplicates but still :) |
| 01:15.39 | NAiL | Consider myself lucky there. It could have kille three PC's, two big monitors, two slugs and more |
| 01:15.59 | Tiersten | yeah |
| 01:16.04 | NAiL | Instead, it killed what was my devslug. |
| 01:16.32 | NAiL | Its memory remains with me ;-) |
| 01:16.34 | Tiersten | Normally a SMPS kills itself when it gets a surge and the device is okay |
| 01:16.43 | NAiL | SMPS? |
| 01:16.43 | Tiersten | How badly scorched is it? |
| 01:16.49 | Tiersten | switched mode power supply |
| 01:16.52 | NAiL | aah |
| 01:17.34 | NAiL | the board was burnt rather badly |
| 01:17.38 | Tiersten | The power supply that comes with the NSLU2 is weird. You can remove the actual plug bit |
| 01:17.52 | Tiersten | Not that I recommend anybody does that because you end up with a death plug |
| 01:18.07 | [g2] | rwhitby-web, I'm with you on the mid-life speed bump |
| 01:18.26 | NAiL | Tiersten: remove plug bit? |
| 01:18.42 | Tiersten | You can remove the actual prongs |
| 01:19.08 | Tiersten | So they can build a single PSU and just put a different set of prongs on it for whatever country they're elling it in |
| 01:19.21 | NAiL | yeah, same as my iPod power sply |
| 01:19.36 | Tiersten | Yeah but you don't get a death plug with the ipod PSU |
| 01:19.48 | Tiersten | That one is designed to take off. The NSLU2 one isn't |
| 01:19.51 | NAiL | hehe, no |
| 01:20.11 | Tiersten | Unless of course you really do want a plug that has two big exposed contacts :) |
| 01:20.45 | NAiL | naah |
| 01:21.05 | NAiL | Anyways, I'll be back to two slugs this afternoon (*should* be this afternoon) |
| 01:21.57 | NAiL | I'll probably get a couple more later :D |
| 01:22.19 | Tiersten | :) |
| 03:14.39 | NAiL | [g2]: ping? |
| 03:14.44 | [g2] | Pong |
| 03:14.50 | NAiL | low latency |
| 03:15.06 | [g2] | I just happened to be looking in the window |
| 03:15.11 | NAiL | :) |
| 03:15.18 | NAiL | I was wondering about APEX |
| 03:15.24 | [g2] | actually, there's 110V hooked to my nads |
| 03:15.28 | NAiL | haha |
| 03:15.55 | [g2] | it *jump* everytime someone sends [g2] |
| 03:16.05 | NAiL | [g2] :) |
| 03:16.10 | [g2] | so what's up with APEX ? |
| 03:16.22 | NAiL | I was wondering about the advantages |
| 03:16.36 | NAiL | Faster bootup, more free flash right? |
| 03:16.46 | [g2] | that's the plan |
| 03:16.52 | [g2] | I think you can get a faster boot |
| 03:17.08 | *** join/#openjtag dyoung-overclk (www-data@netblock-66-159-209-60.dslextreme.com) |
| 03:17.10 | NAiL | It's not faster now? |
| 03:17.22 | NAiL | dyoung-overclk: What are you clocking now? :) |
| 03:17.34 | [g2] | well I'm booting by loading the the kernel from within the jffs2 |
| 03:17.41 | [g2] | that's slower |
| 03:17.54 | NAiL | ah, yes, it was that issue |
| 03:18.06 | NAiL | I so need to get jtag-enabled |
| 03:18.15 | [g2] | because the bootloader is loading up th jffs2 fs nodes and finding and reading out the /boot/bzImage file |
| 03:18.38 | [g2] | to be safe yes |
| 03:18.51 | [g2] | you've got serial right ? |
| 03:18.56 | NAiL | I'm considering flashing maimedslug anyways ;-) |
| 03:19.09 | NAiL | not on maimedslug, actually... That's a slight problem |
| 03:19.25 | NAiL | If I connect the serial, the slug hangs |
| 03:19.26 | [g2] | hence the maimed part |
| 03:20.29 | [g2] | truth be told I haven't been JTAG enabled on any of my slugs (but one has wires attached but I haven't gotten it to work) I haven't tried real hard either |
| 03:20.40 | NAiL | ah |
| 03:20.57 | [g2] | However, I do have JTAG on the Avila board |
| 03:21.10 | NAiL | yeah |
| 03:21.16 | dyoung-reclk | I'm thinking about jtagging lennerts slug. |
| 03:21.16 | [g2] | and can reflash the bootloader and have on that |
| 03:21.22 | dyoung-reclk | I'm not convinced yet. |
| 03:21.27 | [g2] | dyoung-reclk, that'd be awesome |
| 03:21.32 | NAiL | How hard is getting jtag to work? |
| 03:21.35 | dyoung-reclk | Lennerts Dead Slug. |
| 03:21.48 | [g2] | dyoung-reclk, no need for that |
| 03:21.55 | dyoung-reclk | Lennerts Working Slug already has JTAG. |
| 03:22.02 | [g2] | that's really cool! |
| 03:22.09 | dyoung-reclk | he cc'd you the message, I'm sure of it. |
| 03:22.13 | [g2] | nod. |
| 03:22.31 | [g2] | NAiL, you built mysql right ? |
| 03:22.41 | NAiL | eah |
| 03:22.44 | NAiL | yeah |
| 03:22.51 | [g2] | does that build cross ? |
| 03:22.57 | [g2] | or it's it a native job |
| 03:23.02 | NAiL | both |
| 03:23.12 | [g2] | does it work cross ? |
| 03:23.20 | NAiL | the cross build had strange paths and stuff, but that's fixed in mtn now |
| 03:23.31 | [g2] | cool |
| 03:23.46 | [g2] | how long did it take to build native ? |
| 03:23.51 | NAiL | I haven't tested the latest build, but the only changes are paths, so I don't think it breaks that hard. |
| 03:24.08 | NAiL | four-five hours I think |
| 03:24.17 | NAiL | I never remember to time stuff like that |
| 03:24.33 | [g2] | so maybe two-three with TurboFatty |
| 03:24.55 | NAiL | I'd guess around three |
| 03:25.15 | [g2] | I'm playing with apache right now on the TF |
| 03:25.22 | NAiL | It'll swap wildly when it compiles stuff like sql_yacc.c, which takes a fair bit of memory |
| 03:25.47 | [g2] | I've got Apache with SSL running |
| 03:26.10 | [g2] | and does openssl cross build fine also ? |
| 03:26.33 | NAiL | Builds fine, no idea whether it works or not. Haven't touched openssl |
| 03:27.00 | [g2] | ok thx |
| 03:27.10 | [g2] | I'm trying to get the LAMP stuff all sorted out |
| 03:27.17 | NAiL | cool |

| 03:28.04 | [g2] | was it good for you too ? |
| 03:28.05 | [g2] | :) |
| 03:28.51 | NAiL | Oh yes ;) |
| 03:29.13 | rwhitby-web | still no non-IRC turbosluggers |
| 03:29.32 | NAiL | I can stop hanging on IRC, if that'd help? :P |
| 03:29.32 | [g2] | that'll take a while |
| 03:29.55 | NAiL | Ouch |
| 03:29.59 | [g2] | heh |
| 03:30.39 | NAiL | Is anyone "actively maintaining" openslug-uclibc? |
| 03:31.02 | [g2] | I think jbowler-away runs it sometimes |
| 03:31.02 | rwhitby-lunch | nope. You want a job? |
| 03:31.20 | NAiL | I'm considering having one uclibc and one glibc |
| 03:31.27 | NAiL | That means I'd need another slug |
| 03:31.31 | NAiL | ;-P |
| 03:32.06 | jbowler-away | I maintain it as much as I maintain the glibc stuff. |
| 03:32.44 | NAiL | jbowler-away: I'm gonna try the same site-changes for uclibc as for glibc, btw. |
| 03:33.03 | jbowler-away | Yes, that should work |
| 03:33.22 | jbowler-away | I'm not sure yet whether to set up my central file server as uclibc or glibc. |
| 03:33.37 | jbowler-away | If I use glibc I can use NIS, otherwise I have to find something different - openldap. |
| 03:33.39 | NAiL | At the moment, you should choose glibc :-P |
| 03:33.58 | NAiL | Otherwise, all you'd get would be nameless folders |
| 03:34.51 | jbowler-away | Not an issue yet, because I don't have openldap working (I am, at this moment, running and testing stuff on uclibc) |
| 03:36.23 | NAiL | Maybe I should look into openldap when I've set up my newslug |
| 03:37.16 | jbowler-away | I've only done the most basic of tests so far, but samba has a whole load of schemas for it. |
| 03:37.46 | jbowler-away | I hit a RTFM stop point trying to work out how to persuade tinylogin to use the LDAP database not /etc/passwd |
| 03:38.52 | NAiL | I've realized I need quite a few slugs ;) |
| 03:39.16 | dyoung-web | I have 3. Barely enough. |
| 03:39.32 | NAiL | I guess I'll wait until I can get some fat ones |
| 03:40.38 | NAiL | Atleast I'll have a two dedicated buildboxes later this weekend :D |
| 03:41.42 | NAiL | If I'm really lucky, I'll get both a slug and my AMD64 box today |

| 09:15.15 | NAiL | neat |
| 09:17.22 | NAiL | Wow. It's not exactly large numbers ;-) |
| 09:17.46 | ep1220 | Well: it shows we are getting to the max spec of the PSU |
| 09:18.02 | ep1220 | And I have no device on the USB bus |
| 09:18.06 | NAiL | ouch |
| 09:18.22 | ep1220 | The PSU is rated at 2A |
| 09:18.27 | NAiL | it used 1,72A before? That's not enough to have a laptop drive connected? |
| 09:18.47 | ep1220 | USB allows 100mA per device |
| 09:18.56 | NAiL | Isn't that 500mA? |
| 09:19.37 | NAiL | The maximum current that can be supplied over the USB bus without violating the USB specification is 500mA |
| 09:20.00 | ep1220 | Are You sure ? |
| 09:20.47 | NAiL | The minimum it must be able to give is 100mA |
| 09:21.18 | NAiL | but the spec says you can pull 500mA without breaking the specs |
| 09:21.55 | NAiL | aha |
| 09:21.56 | NAiL | High-power, bus-powered devices can draw up to 500mA after they are configured by host system software, but must not draw more than 100mA until they are configured (USB Specification, Version 1.1, Section 7.2.1) |
| 09:22.19 | NAiL | (That's from MicroSoft, but ;) |
| 09:23.02 | ep1220 | I am sure the 100mA are in there, but could well be just for config as you say. |
| 09:23.40 | ep1220 | I believe most USB drives have their own PSU anyway (?) |
| 09:23.46 | NAiL | Most, yes |
| 09:24.18 | NAiL | But some 2.5" drives (I just ordered one. Wonder if it'll work) pull *all* their power from the usb port |
| 09:24.41 | NAiL | s/drives/enclosures) |
| 09:25.01 | ep1220 | So we soon will now if this works :-) |
| 09:25.23 | NAiL | yeah. Not sure whether to smile or not yet :-P |
| 09:25.40 | dyoung-zzzz | i think USB2 spec is 500ma |
| 09:25.52 | dyoung-zzzz | USB1.1 spec is 100ma |
| 09:25.54 | dyoung-zzzz | per port. |
| 09:26.29 | ep1220 | Anyone of you has an IR thermometer and an open slug@266 ? |
| 09:26.40 | dyoung-zzzz | yeah, me |
| 09:26.46 | dyoung-zzzz | its been running for 24 hours now |
| 09:26.51 | dyoung-zzzz | at load avg 2.5 |
| 09:27.18 | ep1220 | I found Q9 (close to the power-on button) regualtes the Core Supply Voltage. |
| 09:27.48 | ep1220 | It now has to supply higher current, so checking its temperature would be good |
| 09:27.59 | dyoung-zzzz | ok, looking |
| 09:30.05 | NAiL | dyoung-zzzz: Yeah, thought it was 500mA. |
| 09:30.22 | NAiL | Weren't there some people running laptop drives off of the slug? |
| 09:30.39 | dyoung-zzzz | I read 42degC on that part. |
| 09:30.52 | dyoung-zzzz | top and bottom of board same temp in that area. |
| 09:31.08 | ep1220 | 42deg is not worry some. |

| 09:42.39 | NAiL | I was hoping to only have one power brick :( |
| 09:42.59 | dyoung-zzzz | you need a bigger brick |

| 09:44.15 | NAiL | wohoo |
| 09:45.04 | NAiL | I was kinda hoping to have ad-hoc POE and two laptop drives. Much less cable clutter. |
| 09:45.57 | dyoung-zzzz | As far as the slugl handling, I dont understand the question. If you put 5V into the input Jack, its gonna use as much as it uses. |
| 09:46.21 | dyoung-zzzz | If youre worried about overcurrent, put a fuse inline. Thats what I'm planning to do. |
| 09:46.55 | NAiL | Yeah, just wondering about e.g. Q9, whether it'll like 1A extra being pulled through it |
| 09:47.09 | dyoung-zzzz | Ohhh... |
| 09:47.15 | dyoung-zzzz | I misunderstood your intention. |
| 09:47.38 | dyoung-zzzz | Q9 is for the core voltage, I dont think it passes the current to the USB HCI |
| 09:47.55 | NAiL | ah, yes... I forgot that part |
| 09:49.24 | NAiL | bbiaw |
| 10:53.26 | ep1220 | NAiL: The current gets directly from the PSU input to the Power Pins on the USB connectors. |
| 10:53.39 | ep1220 | However there is afues in each path |
| 10:53.49 | ep1220 | s/afues/a fuse/ |
| 10:54.36 | NAiL | what's the max rating of the fuses? |
| 10:55.27 | dyoung | Fuse? |
| 10:55.39 | ep1220 | It is FB11 and FB12 at the bottom. |
| 10:55.41 | dyoung | I dont got no fuse.... |
| 10:55.44 | ep1220 | but i saw. FB11 == 0Ohm |
| 10:55.53 | ep1220 | FB12 is not installed at all |
| 10:55.59 | dyoung | ah right. |
| 10:56.17 | dyoung | isnt that like a 1/16 W SMD Resistor |
| 10:56.24 | ep1220 | so on my slug seems only 1 USB port is powered |
| 10:56.29 | dyoung | F1 would usually be the fuse. |
| 10:56.30 | ep1220 | dy: It reads 0 on top |
| 10:56.42 | dyoung | Yeah, but its still a 1/16W part. |
| 10:56.43 | dyoung | so it' |
| 10:56.50 | dyoung | ll blow up after 1/16 W or so |
| 10:57.03 | dyoung | maybe 1/8W, dunno |
| 10:57.27 | ep1220 | Well at Ohm there is more or less no voltage drop. |
| 10:57.36 | ep1220 | so no power dissipated |
| 10:59.27 | ep1220 | At F1 there could be a fuse installed, but it is shorted by FB11 |
| 10:59.46 | dyoung | Unless FB1 really is a fuse. |
| 11:00.22 | ep1220 | I doubt. It looks like a 0 Ohm resistor (there are a few more of this type on the board) |
| 11:01.11 | dyoung | but they are also differnt size and are notated Rxxx |
| 11:01.23 | ep1220 | True. |
| 11:01.24 | dyoung | or Cxxx |
| 11:01.56 | ep1220 | then: maybe they planned a fuse and installed a resistor ? |
| 11:02.07 | NAiL | Rxxx == resistor, Cxxx == Condensator (Or whatever it's in englsh)? |
| 11:02.14 | NAiL | *english* |
| 11:02.19 | dyoung | I'm still working on how the other one gets power. |

| 11:02.27 | NAiL | ah, yes |
| 11:02.43 | NAiL | <-- heating up soldering iron |

| 11:28.30 | ep1220 | s/=/0/ |
| 11:28.44 | dyoung | well, on the top of the board, its bridged to the power. |
| 11:29.13 | ep1220 | I do not see any USB pins on the top of the board |
| 11:29.26 | ep1220 | The USB connectro case is gounded, yes |
| 11:30.01 | ep1220 | Look at the bottom pic - there You see the 4 pins easily |
| 11:30.51 | ep1220 | The Linksys User guide says Flash-Disc will not be recognized on the Disc1 port |
| 11:31.06 | ep1220 | No wonder, if there is no power |
| 11:31.23 | dyoung | I use my flash on port 1 |
| 11:31.36 | dyoung | Re-look at the top picture though |
| 11:31.50 | dyoung | the power pin really is part of the plane. |

| 11:32.26 | ep1220 | we are talking about J3 and J4 ? |
| 11:32.44 | dyoung | Yes, the J3 in particular right? |
| 11:33.44 | ep1220 | there I see 2 solder points, one left one right |
| 11:34.08 | ep1220 | Both are part of the connector shield. |
| 11:34.31 | dyoung | There are the 2 large holes which are part of the housing, then the 4 which are to the usb pins |
| 11:34.56 | dyoung | the middle 2 data ones are in the shape of a 8. |
| 11:35.07 | dyoung | one of the end ones is alone. |
| 11:35.14 | dyoung | the other one is power |
| 11:35.40 | ep1220 | I am looking at NSLU-2-board-front.jpg |
| 11:36.37 | ep1220 | http://www.nslu2-linux.org/wiki/uploads/NSLU2-board-front.jpg |
| 11:36.39 | dyoung | Ippm on http://www.nslu2-linux.org/wiki/uploads/NSLU2-board-front-bare.jpg |
| 11:37.10 | ep1220 | OK, an a bare board one can see the pins ;-) |
| 11:37.45 | ep1220 | The power pin is the right of the 4 in a row |
| 11:38.10 | ep1220 | I see it not connected |
| 11:38.23 | ep1220 | The left one goes to the Ground plane |
| 11:38.46 | dyoung | Oh, youre right. |
| 11:39.04 | dyoung | I had it reversed in memory! |
| 11:39.22 | dyoung | because I was looking at theh board inverted. |
| 11:39.46 | dyoung | Well, thats an interesting point. |
| 11:39.49 | ep1220 | My slug has a FLASH (USB-stick) symbol besides the Disk2 label on the case. Yours 2 |
| 11:39.57 | ep1220 | Yours too ? |
| 11:40.04 | dyoung | Why does my Flash stick work in port 1 |
| 11:40.09 | ep1220 | I do have a recent EU version of the slug |
| 11:40.26 | NAiL | ep1220: mine has too |
| 11:40.37 | ep1220 | Maybe there are different versions ? |
| 11:40.39 | dyoung | It must be connected on the center plane |
| 11:41.01 | dyoung | it has to be |
| 11:41.03 | ep1220 | On my slug power is fed thru FB11 and FB12 - or no power if these are uninstalled |
| 11:41.23 | ep1220 | 5V comes from the PSU connector. |
| 11:41.34 | ep1220 | the power plane is at 3.3V. |
| 11:41.48 | dyoung | its worse than that, because FB12 is for port 2. |
| 11:42.09 | ep1220 | NAiL: then most likely You have no power on USB Port 1 |
| 11:42.30 | ep1220 | dyoung: port 2 is the one closer to the Network connector |
| 11:42.45 | dyoung | Yes, and on my slug, I have no FB12 intalled. |
| 11:42.47 | NAiL | ep1220: yeah, it doesn't have FB12, so I guess not |
| 11:42.55 | NAiL | eh |
| 11:43.46 | ep1220 | dyoung: can you check if You have power on the associated USB pin ? |
| 11:44.30 | ep1220 | NAiL: I think You can install a solder bridge over FB12. |
| 11:44.56 | ep1220 | But it might be possible the PSU gets overloaded if You connect 2 devices drawing power |
| 11:45.20 | dyoung | B oth of my USB ports have 5V |
| 11:45.41 | NAiL | ep1220: Yeah, but if I get a brick that can deliver >2.7A, I'll be ok, right? |
| 11:46.05 | dyoung | There must be a private middle plane for the USB power |
| 11:50.00 | ep1220 | I now can measure 5V too (the probe msut be pressed hard to the pin to get contact) |
| 11:50.08 | dyoung | is that a via near F1? |
| 11:51.15 | ep1220 | i'd say so |
| 11:51.43 | dyoung | thats probably where it comes from. |
| 11:52.12 | ep1220 | nod |
| 11:52.37 | dyoung | I wondered about that for a while too |
| 11:52.44 | dyoung | then it eventually exited my brain. |
| 11:53.41 | ep1220 | I measure 0Ohm between the 2 USB power pins. |
| 12:01.59 | dyoung | Theres a via near FB12 too. Must be a single trace between those two vias |
| 12:02.09 | dyoung | its eveen a straight line. |
| 12:02.35 | ep1220 | But FB12 is open |
| 12:03.05 | ep1220 | There should be another line down to the connector pin (?) |
| 12:06.10 | ep1220 | there must be more +5V in the inner layer. The 5V disappears into an inner layer right at the PSU connector |
| 12:08.28 | dyoung | Oh yes right, its on the wrong side of FB12 isnt it. |
| 12:08.47 | dyoung | as you can probably guess its getting pretty late here. |
| 12:13.56 | ep1220 | NAil: I checked USB powered 2.5 HD enclosing |
| 12:14.09 | NAiL | yeah? |
| 12:14.11 | ep1220 | The datasheet says: 500mA required from USB |
| 12:14.29 | NAiL | which means, I won't get it to work unless I "fix" my slug... |
| 12:14.55 | ep1220 | Well, you need a larger power-supply |
| 12:15.14 | ep1220 | Esp. if Yu want to connect 2 drives |
| 12:15.50 | ep1220 | dyoung found that there is an inner-layer wire which already bridges FB12 |
| 12:15.56 | ep1220 | so no soldering required |
| 12:16.08 | NAiL | cool |
| 12:17.42 | ep1220 | PSU >2.7 will do. if You take a 3A model: you have same power as Linksys PSU + 2x500mA for the drives |
| 12:18.19 | NAiL | yeah |
| 12:28.54 | dyoung-zzzz | ep1220, Thanks for all the help! |
| 12:29.38 | ep1220 | NP |
| 13:24.08 | NAiL | This is gonna be fun |
| 13:24.21 | NAiL | Let's see if I can plug my iPod in without anything blowing up |
| 13:25.01 | NAiL | Ok, it started charging. |
| 13:26.03 | NAiL | The iPod probably pulls 500mAh, since it's basically a USB/FW disk. And it charges the battery while connecte. |
| 13:28.17 | *** join/#openjtag [g2] (~g2@g2.nslu2-linux) |
| 13:41.00 | ep1220 | NAiL: Can the iPod be operated while connected to USB but no battery installed ? |
| 13:41.59 | NAiL | Can't remove the battery at all |
| 13:42.10 | NAiL | Unless I crack open the case with special tools |
| 13:42.24 | ep1220 | not worth it. |
| 13:42.37 | ep1220 | Do you know the mAh rating of the battery ? |
| 13:44.20 | NAiL | 950mAh, I think |
| 13:44.42 | ep1220 | And how long can it play on a loaded battery ? |
| 13:44.42 | NAiL | uh.. might be 720 |
| 13:44.53 | NAiL | It can play for 12 hours or so |
| 13:45.16 | NAiL | But not if the backlight is lit, or if it has to access the disk a lot. It spins down the disk very quickly |
| 13:45.45 | ep1220 | 950mAh/12h = 80mA |
| 13:47.56 | ep1220 | check: http://www.eurobatteries.com/sitepages/stereo.asp |
| 13:48.06 | NAiL | Can't figure out where to read the mAh it pulls |
| 13:48.17 | NAiL | There's some file in /sys or /proc |
| 13:49.20 | NAiL | mhm |
| 13:49.26 | NAiL | only thing it says is C:* #Ifs= 1 Cfg#= 1 Atr=c0 MxPwr=500mA |
| 13:49.52 | NAiL | oh well.. gotta go |
| 15:02.34 | Tiersten_ | ep1220: You can use a 3G iPod without a battery. Don't know about the others |
| 15:03.57 | ep1220 | Tiersten_: this was all about estimating the current the iPod draws from USB |
| 15:04.05 | ep1220 | But NAiL had to go |
| 15:04.23 | Tiersten_ | yeah I know. Just saying that you can disconnect the internal battery |
| 15:04.46 | ep1220 | thx |

| 17:28.03 | NAiL | You'd have to open the case then, wouldn't you? |
| 17:28.35 | Tiersten | Yes |
| 17:28.53 | Tiersten | it's reasonably easy once you know how |
| 17:30.19 | NAiL | Hmm... Can't say I've tried |
| 17:30.44 | Tiersten | There was a bad sector or something on the HD which prevented the iPod OS from loading |
| 17:31.17 | Tiersten | It still worked fine as a firewire/USB disk however so I wiped it clean so it'd default to disk mode and removed the battery because you need the OS to turn it "off" |
| 17:31.25 | Tiersten | Unplugging the firewire or USB would power it down |
| 17:32.46 | NAiL | cool |
| 17:33.06 | Tiersten | It was a very expensive and low duty firewire/USB HD :) |
| 17:33.07 | NAiL | Well, both my iPods are non-faulty, so I don't think I'll do just that yet ;-) |
| 17:33.11 | Tiersten | heh |
| 17:33.20 | NAiL | I got myself another power brick |
| 17:33.26 | Tiersten | For the NSLU2? |
| 17:33.29 | NAiL | 5V 4A |
| 17:33.31 | NAiL | yeah |
| 17:46.00 | NAiL | 2 more amps to play with :D |
| 17:46.28 | Tiersten | The traces are big enough? |
| 17:46.51 | NAiL | Well, I guess we'll find out |

| 20:17.53 | NAiL | Anyone know what "generic" power bricks eat of power? I've heard that an effective brick uses "only" 20%, which in my head equates to the slug not using ~1.7A, but ~1.30A. That leaves enough power to run an USB-powered drive... |
| 20:18.14 | NAiL | I sucks at math though ;-) |
| 20:18.19 | Tiersten | Measure it |
| 20:18.26 | NAiL | How? |
| 20:18.39 | NAiL | All I've got is my multimeter. V, Ohm and buzzer. |
| 20:18.56 | Tiersten | what? it doesn't do amps? |
| 20:19.00 | NAiL | nope |
| 20:19.17 | NAiL | It's really small though :D |
| 20:19.22 | NAiL | And I got it for free. |
| 20:19.26 | Tiersten | Go get a better one :) |
| 20:19.44 | NAiL | bah :P |
| 20:20.07 | Tiersten | Your 4A one is plenty though |
| 20:20.12 | NAiL | But considering the heat output of the slug brick, I'm sure it uses a couple of watts |
| 20:21.19 | Tiersten | Probably |
| 20:21.21 | NAiL | Yeah, haven't had any problems running stuff off the iPod so far atleast. Only problem there is that the iPod spins down the disk after 5 seconds or so, which is a tad annoying :P |
| 20:21.38 | Tiersten | In disk mode? |
| 20:21.43 | NAiL | yeah |
| 20:22.02 | NAiL | I think so? |
| 20:22.18 | Tiersten | Is there a flashing disk on the ipod screen? |
| 20:22.25 | NAiL | no, it isn't. |
| 20:22.29 | NAiL | lemme boot it |
| 20:22.38 | Tiersten | actually, it has to be in disk mode |
| 20:23.23 | NAiL | well.. Dunno if it there's a difference between booting to disk mode or entering disk mode from the running firmware? |
| 20:23.30 | Tiersten | don't think there is |
| 20:23.34 | Tiersten | nothing significant anyway |
| 20:24.05 | Tiersten | does it charge via USB? |
| 20:24.14 | Tiersten | I've only used mine via firewire |
| 20:25.31 | NAiL | yeah, 4th gen ones do |
| 20:25.36 | NAiL | My 3rd gen requires FW |
| 20:25.42 | NAiL | (to charge) |
| 20:25.44 | Tiersten | ah k |
| 20:25.48 | Tiersten | Mine is a 3G |
| 20:27.08 | NAiL | Seems to spin a lot longer when in disk mode |
| 20:28.55 | NAiL | Several minutes, actually |
| 20:28.57 | NAiL | neat |
| 20:29.08 | Tiersten | Okay. THere is a difference then :) |
| 20:29.24 | NAiL | Very nice to know :D |
| 20:29.55 | NAiL | I won't be using the iPod for long, just until I get an enclosure that I can use |
| 20:30.20 | Tiersten | It's probably not good for the HD in the ipod anyway |
| 20:30.24 | Tiersten | for long term usage |
| 20:30.40 | Tiersten | since the ipod was never designed to have the HD spinning constantly |
| 20:30.44 | NAiL | nope |
| 20:30.53 | NAiL | Apple recommended I didn't |
