  • [15:25:27] <SeldanB> does 3A fry the beagleboard?
  • [15:27:35] <muriani> a 3A supply shouldn't
  • [15:27:43] <muriani> the beagle should only draw what it needs
  • [15:27:52] <Crofton> a 12 volt supply will
  • [15:27:55] <Crofton> :)
  • [15:27:56] <muriani> yesss
  • [15:28:06] <muriani> 5V only please :p
  • [15:29:04] <SeldanB> hmm, 5V 3A?
  • [15:29:29] <muriani> I think that's the same as the power supply I have
  • [15:32:16] <SeldanB> i think there is a problem with the usb (both OTG and host)
  • [15:32:46] <SeldanB> I have a device that won't work if attached before the bb reboot and only works when I attach it after linux boots up
  • [15:32:59] <SeldanB> is that a power supply problem? or a driver problem?
  • [15:33:11] <muriani> are you using a USB hub?
  • [15:33:15] <SeldanB> no
  • [15:33:25] <muriani> USB o the beagle can be iffy
  • [15:33:34] <SeldanB> and the usb hub I have doesn't have a powersupply either
  • [15:33:39] <muriani> try using a USB 2.0 hub, and then connecting the device through that if you can
  • [15:33:43] <muriani> oof
  • [15:34:08] <muriani> yeah, you'll want a powered hub, preferably.
  • [15:36:46] <ckrinke> Be careful of some of those universal power supplies with the switches. Many of them do not have a 5V setting and 6V would not be good for the BB
  • [15:37:11] <muriani> yeah
  • [15:37:35] <SeldanB> hmm
  • [15:37:56] <SeldanB> how should I know the difference if they write 5V 3A powersupply?
  • [15:38:07] <muriani> that's fine
  • [15:38:25] <muriani> what ckrinke is referring to is a powersupply that can provide multiple voltages
  • [15:38:41] <muriani> as a "universal" supply
  • [15:38:45] <ckrinke> Sure. The only point is to make sure it is indeed 5V and not even 6V. The BB is very sensitive
  • [15:39:09] <muriani> if you have a voltmeter you can test it.
  • [15:39:12] <ckrinke> If I recall, the spec on the BB says it will handle as much as 5.25V
  • [15:41:07] <SeldanB> hmm, I have a UPS, I only set it to 4.5 and for now, it's working like charm

  • [15:50:53] <djlewis> hi there muriani
  • [15:51:59] <djlewis> SeldanB: what ckrinke is saying is important. DO MEASURE your power supply before long term use.
  • [15:52:18] <muriani> I should probably do that as well
  • [15:52:22] <muriani> need a multimeter
  • [15:52:38] <SeldanB> ok, I ll do that
  • [15:53:04] <djlewis> SeldanB: touch the little ic's near the power / otg jacks and see that thet are only barely warm if at all.
  • [15:53:26] <muriani> I haven't had any issues after getting the hub, myself
  • [15:53:35] <muriani> but I needed the hub anyway
  • [15:53:53] * djlewis needs another cup of coffee :P
  • [15:54:11] <SeldanB> djlewis, I think I will have to add a regulator in this case, it's getting hot
  • [15:54:52] <djlewis> shenki: shut it down now.
  • [15:55:17] <djlewis> SeldanB: ahut it down now.

  • [16:02:47] <ckrinke> The reason I mention this is that my observation is that many universal power supplies from the electronics store intended for use with USB actually produce 6V and not 5V and they cause little hairs to come up on the back of my neck.
  • [16:03:36] <djlewis> SeldanB: no, i am good but I have rad where others have.
  • [16:03:41] <djlewis> rad = read
  • [16:04:10] <djlewis> tnx ckrinke
  • [16:04:57] <djlewis> SeldanB: i have several meters around.
  • [16:05:55] <SeldanB> sadly I have to wait till I return home
  • [16:07:17] <djlewis> SeldanB: your university there may have what you need. look for the electronics engineering dept.
  • [16:08:18] <SeldanB> hehe, it's sunday ;)
  • [16:09:01] <djlewis> SeldanB: or a self powered usb hub will do if you have the cable usb-B to usb-a for the OTG port.
  • [16:15:40] <ckrinke> dj: My self-power hub doesnt seem to work with the BB. I am assuming the register that says "number of mA that can be drawn out of the BB" is set to zero in the Angstrom distribution
  • [16:15:54] <djlewis> SeldanB: or if you have the cable then your computer usb port can power the BB.
  • [16:16:21] <SeldanB> hmm, yeah, I ll try that
  • [16:16:22] <djlewis> ckrinke: YOU CAN ONLY POWER BB WITH THE dc JACK OR otg PORT.
  • [16:17:46] <SeldanB> I think I have the cable for the otg
  • [16:18:53] <djlewis> SeldanB: is your BB revC or later? then you can use the EHCI for all usb functions.
  • [16:20:34] <ckrinke> Huh? I am not powering the BB with the USB interface. I was merely observing that running more then one USB peripheral requires a USB hub and self-powered USB hubs, that is, those that take their power from the host, i.e. the BB, may be problematic
  • [16:20:45] <SeldanB> djlewis: revC3
  • [16:21:15] <djlewis> cool, then tying up the otg to supply power wont be an issue.

  • [17:09:31] <bobkatzz> what OS are you running on the BB? daft-funk ?
  • [17:09:34] <daft-funk> i'm running windows 7

  • [17:11:39] <daft-funk> ah, ok, i was trying to boot Android 1.5 from a specialcomputing provided sdhc
  • [17:11:53] <daft-funk> however, the problem appears even without booting the OS
  • [17:12:52] <daft-funk> because, i think that it should be possible to enter some commands through teraterm when OMAP3 beagleboard.org # is displayed
  • [17:13:07] <adj> ah, no, it's not possible
  • [17:13:15] <daft-funk> ok

  • [17:13:42] <daft-funk> ok, got ya

  • [17:14:31] <muriani> via serial console

  • [17:23:10] <muriani> brb
  • [17:23:46] <djlewis> muriani, I love my rs-232 ports too.
  • [17:24:07] <djlewis> but a good usb to serial works well.
  • [17:24:36] <ckrinke> I had to go to USB-Serial adapters a few years back when laptops stopped shipping commonly with COM1. They work pretty well, although there are two different commoon USB-Serial chips and they tend to need a windows driver installed that usually comes on a CD with the adapter. The adapters tend to be very cheap, like $14
  • [17:25:15] <djlewis> linux picks them up :)
  • [17:25:38] <daft-funk> do you think, if i boot up with windows and use then the adapter it might work???
  • [17:25:48] <ckrinke> coolness. although I thought the OP was dissusing TeraTerm and Windows7, which probably does need the CD\
  • [17:26:04] <djlewis> this DSL is only using 66MB with full GUI and several apps open.
  • [17:26:17] <ckrinke> You can check in control panel under system and drivers to see if it enumerated as COMx
  • [17:26:29] <daft-funk> it is
  • [17:26:31] <daft-funk> as COM3
  • [17:26:35] <djlewis> good
  • [17:26:36] <ckrinke> If it enumerated as a COMx, then just open TeraTerm and select that COM3
  • [17:26:46] <daft-funk> it is already
  • [17:26:55] <daft-funk> and the baud rate and everything is set up
  • [17:27:03] <djlewis> so another problem in wiring.
  • [17:27:05] <daft-funk> it just fails when i try to enter something
  • [17:27:16] <djlewis> but you receive
  • [17:27:20] <ckrinke> And you press the reset button on the BB and just get nothing or "character salad" ?
  • [17:27:21] <daft-funk> yes
  • [17:27:26] <bobkatzz> djlewis: Wow! Sorry I missed the robot debate yesterday - I was in NoVA (DC)
  • [17:27:44] <daft-funk> normal charcters
  • [17:27:47] <daft-funk> it boots again
  • [17:27:47] <djlewis> yep, i was on my own there ;(
  • [17:27:51] <ckrinke> Well, at that point, I would say its a cabling issue as I have the same setup with TeraTerm and a USB-Serial adapter
  • [17:28:14] <bobkatzz> Crofton|work: still looking - will prolly have to go into BB and see what I was doing when the wxWidgets/Python thing came up
  • [17:28:36] <daft-funk> cabling problem where?
  • [17:28:40] <djlewis> hey, I like this nIRC prog
  • [17:28:58] <bobkatzz> it'll be in my .bash_history because I was trying to "opkg" it
  • [17:28:59] <djlewis> daft-funk, you are receiving but not tx'ing, right?
  • [17:29:11] <daft-funk> @djlewis - yes
  • [17:29:54] <ckrinke> 3 wires daft-funk, and only 3 wires. BB-P9-pin2 to DB9-pin3, BB-P9-pin3 to DB9-pin2, BB-P9-pin5 to DB9-pin5
  • [17:30:00] <djlewis> you can test from the pc by unplugging the herder from BB and doing a lopback from tx. rxc with a paper clip.
  • [17:30:04] <djlewis> header
  • [17:30:26] <djlewis> I think that procedure is now in the TRM
  • [17:30:38] <bobkatzz> djlewis: gotta go run an errand but we'll have that bot/robot discussion some time - somewhere ;)
  • [17:30:54] <bobkatzz> basically I agree with you

  • [17:31:06] <_av500_> roboz?
  • [17:31:12] <djlewis> if you unplugg header fromBB and short header pins rx, tx and type on term you should get what you type.
  • [17:31:30] <daft-funk> which header?
  • [17:31:38] <_av500_> ckrinke: i wish it would, would be better than working out...

  • [17:46:11] <daft-funk> and from the ribbon cable coming from the bb

  • [17:50:16] <djlewis> someone port DSL to beagle?
  • [17:50:48] <ds2> why?
  • [17:51:15] <djlewis> I think it would run more efficiently than what we now have, though I may be mistaken.
  • [17:51:41] <djlewis> smaller footprint with or without GUI
  • [17:52:05] <ds2> dsl is big compared to what I am used to
  • [17:52:06] <djlewis> both in memory and cpu usage
  • [17:52:08] <ds2> so *shrug*
  • [17:52:19] <djlewis> ds2: show off

  • [17:54:00] <djlewis> possibilities
  • [17:54:18] <ds2> recent ones?
  • [17:54:30] <djlewis> up to a couple years back
  • [17:55:09] <ds2> are they still using opamps?
  • [17:55:18] <djlewis> looks like a DOD love hate relationship to funding.
  • [17:55:31] <djlewis> totally new technology
  • [17:57:19] <djlewis> ds2: no bookmarks as I am in the Damn Small Linux livecd at the moment.

  • [17:59:28] <djlewis> ok.
  • [17:59:30] <koen> ds2: yeah :)
  • [17:59:53] <ckrinke> My first computer was an IBM 1620, right after I helped Ben Franklin invent electricity
  • [18:00:16] <koen> ds2: funny enough I moved to smaller stuff later on (8MB ram avr32)
  • [18:00:30] <koen> beagle doesn't give you much geek cred in that area
  • [18:01:23] <ds2> i treat the beagle largely as a funny formfactor desktop board
  • [18:01:36] <ds2> it is too powerful compared to say a ARM7

  • [18:04:32] <ds2> djlewis: isn't that basically a stripped down C64/Atari/Apple?
  • [18:04:45] <ds2> koen: do you actually use the touchbook?
  • [18:05:52] <djlewis> ds2: apple was a looong time after 1976

  • [18:08:07] <ds2> didn't know the 6502 had that long of a life time

  • [18:08:43] <bobkatzz> chime heh

  • [18:09:23] <djlewis> yep, I am sentimental too I have hte kim-1
  • [18:09:31] <bobkatzz> and I got the 64k (that's K) memory peripheral

  • [18:14:21] <bobkatzz> then Commodore bought Amiga's "Fat Agnes Chip" technology
  • [18:14:40] <bobkatzz> prolly right
  • [18:14:54] <djlewis> sad thing is that UALR still teaches with it.
  • [18:15:13] <djlewis> teacher never moved on to later technology.
  • [18:16:13] <bobkatzz> in high school my friend and I were studying binary math and built an 8-bit memory "chip" (read block heh) out of 8 DC relays
  • [18:16:33] <djlewis> bobkatzz: that will work.
  • [18:16:53] <bobkatzz> if we would have kept going we would have been about 10 years before Gates and Jobs hehe (I remind him of this all the time!)
  • [18:17:16] <djlewis> bobkatzz: sounds older than water...

  • [18:29:30] <bobkatzz> and the Si570 that has no proptruding feet - just little pad on the side that you are supposed to try to wick the solder up onto - grrr
  • [18:30:09] <bobkatzz> do you have an instructable on how to do that?
  • [18:30:17] <ds2> sorry, nope
  • [18:30:31] <ds2> i was taught by a quick demo from an RF guy
  • [18:30:33] <bobkatzz> that sounds pre-kewl
  • [18:30:46] <ds2> they need a lot of grounding so stock pref boards don't work well
  • [18:31:04] <bobkatzz> make an instructable and the world will beat a path to . . um . . their site hehe
  • [18:31:38] <bobkatzz> so you start with a two-sided copper board?
  • [18:32:16] <bobkatzz> is the polyamide a conductor or non? (would guess non)
  • [18:32:31] <bobkatzz> for isolating copper pads etc?
  • [18:32:55] <ds2> polyamide is a plastic tape they use for reworking. it is nonconductive and handles solder melting temperatures
  • [18:33:05] <ds2> great stuff
  • [18:33:29] <ds2> if I do a write up, it won't be instructables... I _HATE_ their UI
  • [18:33:31] <bobkatzz> nice - does digikey/mouser/newark sell that?
  • [18:33:48] <ds2> they should... Kapton I think is a brand name
  • [18:33:58] <ds2> it is not cheap unless you can find it surplus
  • [18:34:02] <bobkatzz> yeh - was just kidding about instr - not like it either < - - /me
  • [18:34:37] <bobkatzz> surplus?? dude - I know hams!!!
  • [18:34:59] <bobkatzz> they still have fresh, unused stuff from WWII hehe
  • [18:35:33] <ds2> most hams donno aboout that stuff
  • [18:35:44] <djlewis> yeah, and I'm gonna buy mea harley wrapped in cosmylene
  • [18:35:49] <bobkatzz> yeah that's outside the black box hehe
  • [18:35:50] <ds2> it is the industrial/pcb rework surplus that you need to look
  • [18:36:08] <ds2> <-- ham too, familiar with the WWII surplus

  • [18:38:10] <bobkatzz> what I have seen is a couple of guys hacking old Epson flat bed printers to actually print the resist, and in a couple of cases a conducting ink - right onto the board directly
  • [18:38:48] <bobkatzz> that would be cool -
  • [18:39:06] <bobkatzz> not multi layer though
  • [18:39:11] <ds2> that lacks resolution
  • [18:39:31] <ds2> i was looking at milling PCBs but the tools for even 8/8 tracks are too fragile
  • [18:39:40] <bobkatzz> hmmmm I thought is was pretty fine
  • [18:41:02] <bobkatzz> yeah I have a few theat my bor-in-law picked up at a machine shop auction - like 1/32 bit on a 1/4 mandrill but it broke when I just tried to drill a through hole wid it
  • [18:41:24] <ds2> it seem most parts I look at have about 0.5mm pitch
  • [18:41:33] <bobkatzz> theat? wtf? - dunno what that was hehe
  • [18:41:35] <ds2> so that is about 0.020 spacing
  • [18:42:01] <bobkatzz> wow yeah - optical the only way to get that I guess
  • [18:42:06] <ds2> which means I have roughly 0.010 between pads
  • [18:42:24] <ds2> 1/32 is about 0.030
  • [18:42:33] <ds2> hence the issue with milling them :)
  • [18:42:39] <bobkatzz> which to the nano technology guys is like two football fields eheh
  • [18:42:45] <ds2> indeed
  • [18:43:06] <bobkatzz> or a small galaxy :P
  • [18:43:09] <ds2> they make tools down to almost 0.001 but they are fragile
  • [18:43:46] <bobkatzz> we need a "pocket CNC router" to piggyback on the Beagleboard - get on that right away!!
  • [18:44:26] <bobkatzz> what about burning through with an engraving laser?
  • [18:44:26] <ds2> help port EMC
  • [18:44:41] <ds2> engraving lasers tend to be CO2
  • [18:44:50] <bobkatzz> ok got to go out for a bit - bbl
  • [18:44:51] <ds2> the CO2 wavelength gets reflected very well by the copper
  • [18:45:13] <bobkatzz> yeah - hmmm

  • [21:06:54] <julemore> I have Beagle Board ARM 600mhz right? i want to encode frames from a webcam... what do u think is the best resolution may I use? 320? 640? 1024? i dont want to collapse the cpu..
  • [21:07:29] * likewise (n=chatzill@82-171-51-231.ip.telfort.nl) has joined #beagle
  • [21:09:26] <ThomasEgi> julemore, depends on how many frames per second you want to process. and what format you want to encode into
  • [21:14:32] <julemore> fps=30 encode to MP4
  • [21:15:02] <julemore> well i dont really know whats the best format... It will be some kind of surveillance system...
  • [21:15:17] <julemore> H264 perhaps?
  • [21:15:34] <muriani> h.264 is likely a little hefty
  • [21:15:44] <julemore> I want the best ratio quality/bandwith... preferibly bandwidht
  • [21:16:13] <julemore> Listen I will only have a 64Kbits uploading channel
  • [21:16:47] <ThomasEgi> cant you use the DSP for encoding?
  • [21:17:10] <julemore> hmmm I dont know if I can... ffmpeg uses it?
  • [21:17:32] <julemore> How can I use DSP for a webcam?
  • [21:17:44] <ThomasEgi> dunno
  • [21:17:47] <ThomasEgi> was just an idea of mine
  • [21:18:12] <ThomasEgi> i doubt that a 600mhz cpu can encode video at 30fps at higher resolution than 320x240
  • [21:18:16] <julemore> well but DSP is just like OPENGL... software can use it or not righT?
  • [21:18:33] <muriani> you have to write code to use it
  • [21:18:36] <julemore> Thomas but what encoding format?
  • [21:18:48] <julemore> mp4??
  • [21:19:01] <ThomasEgi> mp4 would be ways to processing intense
  • [21:19:11] <ThomasEgi> i'd go for some already existing streaming standards
  • [21:19:19] <ThomasEgi> such as h.263
  • [21:19:44] <julemore> Has h.263 lower bandwith than MP4?
  • [21:19:49] <ThomasEgi> no
  • [21:19:51] <Yuvi> TI has DSP codecs
  • [21:20:03] <julemore> whats TI?
  • [21:20:08] <Yuvi> but 64 kbit won't stretch very far
  • [21:20:11] <ThomasEgi> texas instruments
  • [21:20:17] <julemore> ooh
  • [21:20:27] <muriani> julemore: the company that created the OMAP3 in the Beagle.
  • [21:20:32] <ThomasEgi> 64kbit is barely enough for some semi-acceptable 320x240 vid
  • [21:20:39] <julemore> yeah yeah i know about TI
  • [21:20:43] <julemore> :)
  • [21:20:43] <Yuvi> I'd go for qcif + h264
  • [21:20:49] <muriani> 64kbit is barely enough for acceptable audio :p
  • [21:21:20] <ThomasEgi> ifyou have voiceonly thats enough
  • [21:21:22] <ThomasEgi> even less is fine
  • [21:21:29] <muriani> well yeah.
  • [21:21:43] <muriani> I wasn't talking about voice though :)
  • [21:21:46] <ThomasEgi> for "full" audio it's wuite thight
  • [21:21:50] * mrc_001 (n=mrc_001@91-114-191-13.adsl.highway.telekom.at) Quit ()
  • [21:21:50] <julemore> muriani.. yeah but... what about fps=20 160x120 and 64kbits? is it possible?
  • [21:22:06] <ThomasEgi> julemore, why not give it a try
  • [21:22:19] <Yuvi> x264 should hit that easy, dunno about quality though
  • [21:22:23] <ThomasEgi> encode some random video at the resolution and codev you like
  • [21:22:35] <ThomasEgi> and see what bandwith it uses
  • [21:22:47] <ThomasEgi> you dont even need to stream it
  • [21:22:52] <julemore> ok i will.. but i need to know which codec creates de LESS bandwidth and acceptable cpu power usage
  • [21:23:17] <ThomasEgi> well i'd say 160x120 vid will run in any case^
  • [21:23:24] <Yuvi> bitrate wise, there really isn't anything that beats h.264
  • [21:23:32] <ThomasEgi> jeah
  • [21:23:40] <ThomasEgi> but if its streaming you can run into paketloss too
  • [21:23:46] <ThomasEgi> dunno how well h264 handles that
  • [21:23:48] <julemore> so h.264 is the choice ok
  • [21:24:05] <ThomasEgi> i would suggest some slightly older format
  • [21:24:13] <ThomasEgi> maybe a good old mpeg ts stream
  • [21:24:22] <muriani> h.263 even should be ok, I'd think

  • [21:24:39] <julemore> what about fmmpeg?
  • [21:24:40] <ThomasEgi> for 320x240 and less. that should work quite ok
  • [21:24:47] <julemore> is there some bitbake fmmpeg?
  • [21:24:47] <julemore> lol
  • [21:25:01] <julemore> or opkg ffmpeg?
  • [21:25:04] <Yuvi> h.264 has some advanced stuff to deal with packet loss, but like nothing implements it
  • [21:25:05] <ThomasEgi> theora might also be a choice
  • [21:25:06] <jin> hello
  • [21:25:19] <jin> i did opkg install opencv
  • [21:25:33] <ThomasEgi> i wouldnt go for h.261 , despite it streams good the quality lacks
  • [21:25:58] <jin> and samples
  • [21:26:10] <jin> but i can't find /usr/share/opencv
  • [21:26:38] <jin> i want to use opencv on beagleboard
  • [21:27:08] <jin> i followed the process which posted on beagleboard google group
  • [21:27:11] <muriani> has there been any improvement on opencv on beagle? Last I heard it was quite slow.
