00:42.58joe_bleauprpplague: I
00:43.09joe_bleauve been reading the logs recently, and it seems as though this
00:43.14joe_bleauchannel has become #hammer!
00:43.28CosmicPenguinyou have a problem with that?
00:43.48joe_bleauNo, and would it matter if I did?  ;-)
01:07.22jbevrenhehe
01:07.27jbevrenit will for a while be #hammer
01:07.32jbevrenjust as it was #zipit for a while
01:07.35jbevrenand #pixter
01:07.36jbevren:)
01:07.43jbevrenthat said, a #hammer channel's not a horrible idea
01:09.11joe_bleauIt's nice to see a bump in the amount of discussion/traffic.
01:12.57jbevren:)
01:13.04jbevrenI really cant wait to poke at mine
01:14.03jbevrenafk
01:38.47T0mWHammer? did someone say "Hammer"?!

02:24.53jbevrenno vfat in my hammer kernel :P
02:25.05jbevrenI was hoping t use my usb stick to move data quickly

02:47.01jbevrenhmm
02:47.14jbevrenoverclocker forums seem to agree on using JBweld for thermal epoxy
02:47.22jbevrencurious. :P]
02:47.29jbevrenbye tom :)
02:47.56jbevrenthe only challenge left is getting the heatsink shaped to not rest on teh caps around the hot regulator

03:04.42jbevren640x400x1bpp
03:15.57jbevrenhm my hardcopy datasheet is incomplete :X
03:16.02jbevrenfound one online heh
03:16.08jbevrenits DSTN 1bpp 4bit parallel
03:19.44MonMothadual scan 1bpp?
03:19.47MonMothanow that's odd...
03:19.52jbevrenits way old
03:19.53jbevrenheh
03:20.03jbevrenyou feed it 8 bits in parallel
03:20.04MonMothaI would think that most 1bpp would be single scan
03:20.09jbevrenfour go to the upper half, four go to the lower half
03:20.17jbevrenthe thing has um
03:20.25jbevren19 ICs on it
03:20.28jbevrenall the same heh
03:20.39jbevrenEL backlight, yellow transflective
03:21.00jbevrenhttp://www.allelectronics.com/cgi-bin/category.cgi?category=search&item=LCD-103&type=store
03:21.08jbevrencost me $8 :)
03:21.19jbevrenthe power requirements are equally scary
03:21.24jbevrenI imagine the backlight wants 100vac
03:23.38jbevrengot gpsfan's URL by chance?
03:27.20GPSFanjbevren: you called?
03:27.29jbevrenwow youre up late :)
03:27.36jbevrenwhats the URL to your hammer pictures?
03:27.53GPSFanhttp://www.paonia.com/~kenm/Pix/?dir=images/Hammer
03:27.59jbevrenthanks :D
03:28.15jbevrenI was telling a friend in minnesota about the hammer and he wanted more images than the wiki has
03:28.58GPSFanI replaced the 5V linear reg with a switcher, now I've got plenty of 5V for usb things.
03:29.02MonMothajbevren: those backlights are meant to be run off a small inverter
03:29.10MonMothasince they usually want fairly high frequency AC
03:29.13MonMothaaround 100-500kHz
03:29.23jbevrenMonMotha: yeah
03:29.31jbevrenI figured on using an old CF inverter circuit
03:29.33GPSFanjbevren: you try using the supplied buildroot yet?
03:29.40jbevrenGPSFan: I havent
03:29.50jbevrenI just moved back home, and my official PC isnt set up yet :X
03:30.00jbevrenI'm on a 300mhz subnotebook atm heh
03:30.00GPSFanmine stopped during binutils build with an error
03:30.09jbevrenwhat was the error?
03:30.19jbevrennot that you couldnt figure it out, I'm just curious
03:30.44GPSFancan't really figure it out, it seems like something to do with makeinfo being missing from my host system'
03:31.15jbevrenI think I'll just install debian on my old amd64 and use it for dev
03:31.39jbevrenMonMotha: other than being 5vdc, I think this lcd is usable
03:31.48GPSFanhttp://www.pastebin.ca/677540
03:31.52jbevrenI just need to figure out if the CPU can be configured to feed it data :)
03:33.32GPSFanI was hoping prplague would be back this evening.
03:33.39jbevrenyeah, makeinfo's missing
03:33.50jbevrenI'd recommend going into the source tree and disabling the make directive for um
03:34.01jbevrenbinutils*/bfd/doc/
03:34.08jbevrendont need no stinking docs
03:34.11jbevren:D
03:34.29jbevrenespecially not those for info (I hate info)
03:35.27jbevrenGPSFan: btw, Ive been reading on OC forums
03:35.35jbevrenJBweld seems to be an acceptable thermal epoxy
03:35.39MonMothawhat's wrong with 5V?
03:35.53jbevrenso I may use a small heatsink and a dot of JBweld on that 5v reg
03:36.13jbevrenit gets pretty hot with my usb stick plugged in
03:36.23GPSFanindeed. where? there are several places, /toolchain/build_arm ?
03:36.31jbevrenhrm
03:36.45jbevrenyeah
03:36.52jbevrenthats where the current stop is occuring
03:36.53GPSFanthe wally is putting out 13V under load, so that poor little linear is dropping a lot.
03:37.03jbevrenoh wow
03:37.05jbevrenI never measured it
03:37.09jbevrenit claims 9v heh
03:37.19GPSFanOC it"s >15V
03:37.25jbevrenI have some 5v wallwarts (regulated, 1amp)
03:37.41jbevrenIve been pondering bypassing that reg
03:37.56GPSFanthat's what I would have used rather than an el-cheapo unreg POS
03:38.12jbevrendlink hardware comes with em heh
03:38.22jbevrenIve had two wireless APs die on me, so I have a couple spares
03:38.23MonMothayou could also use something like a 9V wart
03:38.27MonMothawhich are reasonably common
03:38.30jbevrenMonMotha: the wart IS 9v
03:38.33jbevrenits putting out 13
03:38.35MonMothaok, so a REAL 9V wart
03:38.44jbevrenhehe a regulated 9v?
03:38.54MonMothathey always run high open, but they should drop to 9-10 under load
03:39.01jbevrenyeah
03:39.07MonMothaI have some regulated 9V warts
03:39.09jbevrenprob is, the hammer draws around 150ma
03:39.15jbevrenso its not much load on its own
03:39.21jbevrenGPSFan: how goes your ethernet texperiments?
03:39.25MonMothathat's usually enough to bring them down closer to spec
03:39.32jbevrenI see you have one of sparkfun's breakouts in your gallery
03:39.35MonMothaI've also seen 7.5V warts
03:39.46jbevrenMonMotha: right, I have one left over from an old powerbook:)
03:39.51jbevrenthats not a bad idea too
03:42.07GPSFanjbevren: well I was getting a toolchain up so I could compile some stuff, but got stopped by that error. I still can't figure out where or what to change. ;>(
03:42.38jbevrenGPSFan: Check the makefile in the parent dir, see if it refers to the directory with the stop
03:42.45jbevrensince its a doc dir, just remove its reference
03:42.53jbevrenor maybe
03:43.03jbevrenln -s /bin/true /usr/local/bin/makeinfo
03:43.06jbevren:)
03:43.19jbevren(who needs info docs!)
03:43.35jbevrensee if that breaks anything else
03:48.47GPSFanadding the link resulted in the same error.
03:48.53jbevrencurious
03:49.58jbevrenthe directive thats failing is bfd.info
03:50.24GPSFanoh well, I'll poke at it tomorrow almost time for Dr. Who ...

05:52.44MonMothayou can get low-ish current ones (500mA or so) about the same size as a D2PAK or TO-220
05:52.56MonMothacontroller + inductor + diode
05:53.10MonMothathe filter cap obviously takes up some room, but most linears need some sort of output cap, too

16:11.48GPSFanjbevren: not yet, I haven't gotten started on hammering yet today.
16:12.11jbevrenuhoh, it's become a verb
16:12.12jbevren:)
16:13.21jbevrenGPSFan: doy ou know much about the lcd controller on the chip?
16:14.40GPSFanjbevren: you mean in cpu, no haven't had a chance to look at it yet, ethernet first, then I have a small 640 x 480 dstn lcd I want to hook up.
16:17.12jbevrennod
16:17.20jbevrenI have a DSTN 1bpp 640x400 lcd heh
16:17.38jbevrenI need to find out if the hammer can drive dstn :)
16:20.48jbevrenlol
16:21.01jbevrenoopsie!
16:29.12jbevrenlol
16:29.19jbevrenthe kernel assuems year 1969
16:32.38GPSFanjbevren: no hardware RTC

16:37.08jbevren<PROTECTED>
16:37.19jbevrenI was aware of no hardware rtc btw, thats why I was curious about the date:)
16:38.48GPSFanbuildroot is building ;>)
16:39.03jbevrencool :)
16:39.08GPSFanwe don't need no stinkin makeinfo...
16:39.09jbevrenadd a note to the wiki ;-)
16:39.16jbevrenwho needs docs?! ;)
16:55.59GPSFanbuildroot has built..
16:56.13GPSFana root and other stuff ;>)
16:56.25jbevrenyay
16:56.26jbevrenlol
16:56.46jbevrenI'm gonna jet
16:56.50jbevrenfamily will be in town soon
16:56.56jbevrenGPSFan: Have fun hammering :)
16:58.29GPSFanit didn't build a kernel though, I see it's disabled in the hammer-config for buildroot. well that's next.
17:00.24ExilesI have a I2C rtc

17:06.27GPSFanExiles: that would be a nice How-To,  "add a real RTC to your hammer"
17:06.50ExilesI'm stuck in kernel hell
17:07.31GPSFanhammer kernel?
17:07.56Exilesyeah, trying to get adm8511 support into it
17:08.25GPSFan<PROTECTED>
17:08.28Exilesusb network adaptor
17:08.42GPSFanthere seem to be 2 kernel versions on the cd
17:08.45Exileslet the build root build it first
17:09.01Exilesbut I need to actully change the kernel
17:09.04GPSFandid the bin's match what came on the cd?
17:09.14Exilesand it's harder to do that
17:09.29Exilesyeah, got it to compile right
17:10.44GPSFank, I'll try enabling it in buildroot and see what happens. The rootfs buildroot built is somewhat larger than on the device, more stuff compiled in busybox, and missing some small utilities.
17:16.15Exilesat least you have water
17:16.23Exileshttp://picasaweb.google.com/wired57/WaterMain
17:17.57GPSFanExiles: what did you use for a .config?
17:18.30Exilessame .config in the buildroot
17:18.43GPSFanfor the kernel that is.
17:19.34Exilesthinking that maybe I needed to use the copy of the kernel from the disk, and not from the build root
17:19.44Exileswith it placed in the vuild root dir
17:20.10GPSFanone is 2.6.22.1 one is 2.6.22
17:21.57GPSFandave said at one time that the kernel source that came on the cd was pre patched for hammer. I wonder which one he meant?
17:22.16ExilesI'm not sure
17:25.52GPSFanthe one that isn't in buildroot has a hammer-config in its root. and there is a mach-tct_hammer is arch/arm/mach-s3c2410/
17:26.07GPSFanI'd bet that's it.

17:36.51Exilesyeah
18:51.36GPSFanExiles: missing beeper-gpio.h I had to patch mach-tct_hammer.c to remove references to the beeper as I have no clue what dave wanted in the missing .h file. the kernel compiled, and the zImage is very close in # of bytes.

20:09.39GPSFanExiles: ah, (I'm kinda slow) now I get your comment about having water. well you have water too, just not quite where it's supposed to be, and in quantities that are not quite suitable for many household purposes.
