May 30 18:22:52 <ulterior_modem> hey, is anyone here that has opened their guruplug?
May 30 18:23:42 <jzaw_pl> not here ... but have you seen that mod link?
May 30 18:26:04 <ulterior_modem> No, could you link me?
May 30 18:26:18 <ulterior_modem> I've got mine open right now messing with it, and I've noticed a little quirk.
May 30 18:26:48 <ulterior_modem> I'm alsu going to mod mine, hence my noticing of this.
May 30 18:27:10 <ulterior_modem> Mine has an antenna plug like you'd find on a laptop minipci card for wifi.
May 30 18:27:15 <jzaw_pl> looking for the link for you
May 30 18:27:34 <ulterior_modem> So I thought I'd remove the board from its case and test this with an antenna I've got.
May 30 18:27:51 <jzaw_pl> http://plugcomputer.org/plugforum/index.php?topic=1735.0
May 30 18:27:54 <jzaw_pl> something like that
May 30 18:27:55 <ulterior_modem> When I connect the antenna, I get no signle at all.
May 30 18:28:04 <ulterior_modem> **signal.
May 30 18:28:06 <jzaw_pl> if you click the pics ... youll get more offered
May 30 18:28:17 <jzaw_pl> do you have any pics of the innards
May 30 18:28:23 <jzaw_pl> esp the wifi antenna?
May 30 18:28:47 <jzaw_pl> btw ... a good idea might be to replace the internal psu with an external 5v 2-3A one
May 30 18:28:49 <ulterior_modem> there isnt an antenna besides the one in the chip
May 30 18:29:04 <ulterior_modem> but theres a plug for one inside.
May 30 18:29:05 <jzaw_pl> nothing like a printed circuit track ?
May 30 18:29:11 <jzaw_pl> ah
May 30 18:29:22 <jzaw_pl> that suggests you can externalise the antenna
May 30 18:29:22 <ulterior_modem> none that I see.
May 30 18:29:25 <ulterior_modem> yes
May 30 18:29:30 <jzaw_pl> good
May 30 18:29:42 <jzaw_pl> just one little pressstud type of connector or 2 or 3?
May 30 18:29:58 <jzaw_pl> its 802.11b/g/n isnt it?
May 30 18:29:59 <ulterior_modem> which is what I wanted to do, because the the reception is as horrible as one imagines.
May 30 18:30:05 <ulterior_modem> its b/g.
May 30 18:30:08 <jzaw_pl> not n?
May 30 18:30:13 <ulterior_modem> nopes
May 30 18:30:15 <jzaw_pl> aw shame
May 30 18:30:22 * jzaw_pl shakes his head to try to remember
May 30 18:30:24 <jzaw_pl> you sure?
May 30 18:30:29 <jzaw_pl> this is the guru isnt it?
May 30 18:30:49 <ulterior_modem> yeah
May 30 18:31:19 <ulterior_modem> its bg, I'm for sure.
May 30 18:31:23 <jzaw_pl> damn youre right
May 30 18:31:23 <jzaw_pl> • Linux Kernel 2.6.32 • Wi-Fi 802.11b/g • Bluetooth: 2.1 / EDR • U-SNAP I/O
May 30 18:31:23 <jzaw_pl> • 7x GPIOs for user application- 5 with 3.3V I/O, 2 with 1.8V I/O
May 30 18:31:23 <jzaw_pl> • Optional with SPI Flash + SD card boot up • UBIFS Flash file system support • NAND Flash boot up
May 30 18:31:35 <jzaw_pl> thats a shame
May 30 18:31:40 <ulterior_modem> So as for this antenna deal. When I connect my known-good antenna, the signal bottoms out.
May 30 18:31:47 <jzaw_pl> is it built in or is it a daughter card?
May 30 18:32:30 <ulterior_modem> its on the daughter card with what I think is the wifi chip and the sdreader.
May 30 18:33:05 <jzaw_pl> pls can you do some photos?
May 30 18:33:23 <ulterior_modem> sure, lemme grab my camera.
May 30 18:33:24 <jzaw_pl> as high resolution as you can manage
May 30 18:33:29 <jzaw_pl> ace ... thanks
May 30 18:49:37 <ulterior_modem> alrighty, U52667
May 30 18:49:52 <ulterior_modem> err... http://www.flickr.com/photos/8878847@N05/ .
May 30 18:49:55 <ulterior_modem> There we go.
May 30 18:56:25 <jzaw_pl> awesome vid about how to work in the marvell prompt
May 30 18:56:27 <jzaw_pl> http://hackaday.com/2010/01/20/sheevaplug-pbx/
May 30 18:56:34 <jzaw_pl> he actually does a uboot flash
May 30 18:56:39 <jzaw_pl> via tftp
May 30 18:56:43 <jzaw_pl> and some other stuff
May 30 18:58:56 <jzaw_pl> great photos ulterior_modem do you have any shots of the psu pls?
May 30 18:59:08 <jzaw_pl> thats the contentious piece in the guru eh
May 30 18:59:34 <ulterior_modem> yeah in a bit. The PSU looks pretty nasty. I've got to do something now, brb.
May 30 19:12:03 <NightMonkey> ulterior_modem: What's the wire up the tree doing?
May 30 19:15:16 <ulterior_modem> NightMonkey: It is from a set of photos I havent uploaded completely. A neighbor of mine tried to steal cable and jacked the distribution box at the bottom. looks like a rats nest.
May 30 19:15:23 <ulterior_modem> I just thought that one look neat.
May 30 19:20:39 <NightMonkey> ulterior_modem: Mmmm.... the Interweb eats more evidence. ;)
May 30 19:21:01 <NightMonkey> ulterior_modem: Thanks for the guru* interior pics.
May 30 19:21:10 <jzaw_pl> yeah theyre great
May 30 21:01:37 <rektide> well
May 30 21:01:42 <rektide> glad i didnt purchase those 2-3 guruplugs
May 30 21:01:47 <rektide> given the overheating BS
May 30 21:02:05 <rektide> just wish i had an alternative. :(
May 30 21:02:06 <jzaw_pl> does seem somewhat worrisome
May 30 21:02:23 <jzaw_pl> i got a white sheevaplug esata multi
May 30 21:02:31 <jzaw_pl> and was assured that it had a new psu design
May 30 21:02:58 <rektide> didnt know sheevaplugs were out in esata variety
May 30 21:03:18 <rektide> thats the reason i went OpenRD on day 1 (and lets say this OpenRD hasnt been flawless)
May 30 21:04:10 <jzaw_pl> so far so good for my sheeva
May 30 21:04:19 <rektide> where did you get it?  i'm not ....
May 30 21:04:41 <jzaw_pl> http://www.newit.co.uk/shop/proddetail.php?prod=eSataSheevaMulti
May 30 21:04:44 <jzaw_pl> uk
May 30 21:05:07 <jzaw_pl> ive had it two weeks
May 30 21:05:08 <rektide> damn, nice
May 30 21:05:20 <jzaw_pl> i also did a small write up how to boot off esata disk
May 30 21:05:54 <rektide> i havent checked OpenOCD in a while
May 30 21:05:58 <rektide> errm
May 30 21:06:01 <rektide> uboot, sorry
May 30 21:06:23 <rektide> last spring i spent colossal amounts of time compling uboot and trying fancy boot configs
May 30 21:06:27 <jzaw_pl> https://dizzykey.co.uk/sheeva-boot-esata.txt
May 30 21:06:27 <rektide> never did get esata going
May 30 21:06:41 <jzaw_pl> key things are the uboot version
May 30 21:06:44 <rektide> actually never did get much going w/r/t getting mainline uboot on openrd. ;)
May 30 21:07:17 <jzaw_pl> and then of course the kernel
May 30 21:31:30 <ulterior_modem> Just by the way, I realized you couldnt look at the large view of those pics due to a setting in my profile. Thats changed, so you can now look at the big version.
May 30 21:47:01 <NightMonkey> WARNING: *plugs not recommended for igloo usage.
May 30 22:26:30 <MoDaX> well, my guruplug plus stays ~40-42C. I guess this isn't so bad, is it?
May 30 22:32:15 <NightMonkey> MoDaX: I need a IR thermal temp measuring tool. It just feels hot., especially the metal parts.
May 30 22:33:12 <NightMonkey> MoDaX: And this is at idle. I'm not stressing it CPU-wise yet.
May 30 22:33:24 <NightMonkey> MoDaX: Have you measured at load?
May 30 22:35:14 <NightMonkey> So far I'm not unhappy, since I bought this for educational purposes, and secondarily for evaluation for deployment. So, for education, it's working out well.
May 30 22:44:13 <MoDaX> NightMonkey: idling atm. however, I tried running an endless shell loop for 30 min and it didn't get much hotter
May 30 22:46:20 <jzaw_pl> i did several big compiles .... ffmpeg and zoneminder
May 30 22:46:49 <jzaw_pl> and though ffmpeg went on for aaages about 40 -50 mins at max processor ... the sheeva didnt get unbearably hot
May 30 22:47:01 <jzaw_pl> warm .. fairly warm ... but not hot
May 31 00:02:48 <Tootoot222> < NightMonkey> MoDaX: And this is at idle. I'm not stressing it CPU-wise yet.
May 31 00:02:55 <Tootoot222> i don't think it will get hotter when under a high load
May 31 00:03:04 <Tootoot222> it has no power management
May 31 00:03:12 <Tootoot222> bogomips are the same as real instructions
May 31 00:03:22 <Tootoot222> so if it's hot, that's the hottest it should get
May 31 00:03:30 <Tootoot222> even at 100% cpu
May 31 00:03:39 <Tootoot222> now, if you have a usb or something that generates heat too
May 31 00:03:42 <Tootoot222> that could add to it
May 31 00:03:57 <Tootoot222> but i don't think that stressing the sheeva cpu will create much heat, if any
May 31 00:04:03 <Tootoot222> (sheeva/guru)
May 31 00:09:19 <NightMonkey> Tootoot222: Hrm. I have x86 CPUs without power management, and they get hotter with more work. This is something specific to ARM that that doesn't happen in that arch?
May 31 00:10:52 <Tootoot222> i'll bet you could scale those x86 though?
May 31 00:11:02 <Tootoot222> on idle they would drop to a lower clock speed
May 31 00:11:10 <Tootoot222> the sheeva board would stay at it's max
May 31 00:12:52 <ShadowJK> it has cpuidle though
May 31 00:13:04 <ShadowJK> where cpu switches off until next work
May 31 00:13:40 <Tootoot222> well with linux you always have some daemons or something running (crontab? dbus?) that do some work every few seconds
May 31 00:14:02 <Tootoot222> unless you're in like, the uboot-halt mode
May 31 00:14:08 <Tootoot222> where you're at the env prompt thing
May 31 00:14:23 <Tootoot222> it'll still be speeding along doing nothing
May 31 00:14:45 <ShadowJK> if cron wakes up every few seconds it's broken
May 31 00:15:15 <ShadowJK> CPU is probably less than half the power consumed even at max anyway though
May 31 00:15:52 <Tootoot222> what would be the most power intensive (assume you're not using usb or sd)
May 31 00:19:21 <ShadowJK> ram and gigabit I'd think
