12:08 AM XXCoder: lol
12:43 AM XXCoder: nice video https://www.youtube.com/watch?v=_-HSP9plW1I
12:44 AM XXCoder: curve milling as ugly as sin tho]
12:44 AM XXCoder: in least they ciuld clean it up afterwards

01:44 AM XXCoder: new bad obession video!
01:49 AM Deejay: moin
01:50 AM XXCoder: yo
03:20 AM russian_troll: selroc: Today's Log http://www.isaeff.net/logs/%23linuxcnc/2019-02-04.html
04:41 AM jthornton: morning
04:47 AM XXCoder: hey jthornton its snowing here lol
04:47 AM XXCoder: actually a inch thick. major nosw
04:47 AM XXCoder: snow
04:57 AM jthornton: wow
04:57 AM XXCoder: heh bet its just little snow to you :)
04:58 AM XXCoder: im wondering if places will close tomorrow, but then we have hefy snow equipment due to east washington being more snowy
04:59 AM jthornton: snow can be bad if people are not used to driving on it
04:59 AM XXCoder: yeah lucky im pretty good anyway
05:36 AM Tom_L: 44°F Lo 29
05:54 AM jthornton: morning
05:55 AM XXCoder: 31f snowing
05:56 AM XXCoder: looks like it MIGHT snow again this friday. pretty amazing
06:12 AM Loetmichel: gnihi... my apprentice has to make a 24" TFt display for a customer. Bad: the monue button PCB doesent fit the new Enclosure... Now the apprentice has a crash-course in Target3001 (PCB CAD) and Insulation milling on the CNC 6040 ;)... but i doubt that he remembers any of my "turbo-explaining" ;)
07:07 AM jthornton: https://forum.linuxcnc.org/41-guis/35974-bp-knee-mill-touch-screen-gui
07:08 AM XXCoder: man
07:08 AM XXCoder: 'i am loving that ui
07:08 AM jthornton: thanks
07:09 AM jthornton: I put the -0.250 and 0.250 on the set offset because my dowel in the spindle is 0.500"
07:09 AM jthornton: I need to update the image lol
07:16 AM XXCoder: :)
07:17 AM jthornton: https://github.com/jethornton/bp_touch
09:14 AM jesseg: hey guys, I noticed something very interesting with a liquid level. If your shop is cold and you touch one end of the liquid vial, the bubble immediately starts moving toward your warm finger...
09:14 AM jesseg: Shining an led flash light or green laser pointer on one end of the vial can do the same thing
09:17 AM jesseg: It must either be due to the vial expanding and kind of dome-ing up or the fluid warming up and becoming less dense
09:28 AM SpeedEvil: yes. Don't do that.
09:28 AM SpeedEvil: The shape of the vial is very very carefully controlled.
09:29 AM SpeedEvil: And also thin.
09:40 AM Loetmichel: depends on how sensitive the level is i presume, jesseg
09:40 AM Loetmichel: the usual "construction" levels are pretty coars. i doubt you would get that kind of reaction to temperature with them
09:42 AM SpeedEvil: I should try it on my starrett master precision level.
09:42 AM SpeedEvil: Alas, I don't own one.
09:42 AM Loetmichel: a machine level however is usually good for a single mm per meter inclination measurement... meaning that the slightes "encouragement" in form thermal expansion or currents inside the liquid is enough to move the bubble
09:43 AM jesseg: Loetmichel, I dunno, you might be surprised. I first noticed on a 1-arc-minute per div level on a theodolite, but then I tried it on the round all-direction roughing level which is 8 arc-minutes per div, and it even showed drastic behavior
09:43 AM jesseg: actually there might be a construction level around here... lemme go look.. LOL
09:44 AM Loetmichel: interesting
09:44 AM Loetmichel: i would have thought that the coarse ones would have enough "byoancy" to counteract those effects
09:44 AM jesseg: yeah
09:45 AM jesseg: well can't find the construction level
09:45 AM Loetmichel: <- has proven in experiment that SOME levels still have glass vials in them
09:45 AM jesseg: lol
09:45 AM jesseg: *had* glass in them :P
09:45 AM Loetmichel: <- had to pick the shards out of his face after it came in close contact with a hot air gun ;)
09:46 AM jesseg: oh ouch.
09:46 AM Loetmichel: indeed, HAD
09:46 AM Loetmichel: simply exploded like those sprinkler nozzle vials ;)
09:46 AM jesseg: did you notice how small the bubble got before it went?
09:46 AM Loetmichel: <- needs glasses to see anything, so no harm done ;)
09:47 AM Loetmichel: nope, was too fast
09:47 AM SpeedEvil: I have wondered about simply adding some glass over, and backlighting.
09:47 AM Loetmichel: i imaigine it disappeared
09:47 AM Loetmichel: the bubble i mean
09:47 AM jesseg: I dunno, the bubble is a significant portion of the volume
09:48 AM Loetmichel: only problem was that the shards were SO small that it took quite a while and some searching to get them out of the skin
09:48 AM Loetmichel: looking for the blood trickles worked pretty well though ;)
09:48 AM Loetmichel: s/trickles/spots
09:49 AM Loetmichel: could also be that the vial simply exploded because of overpressure and some pretension relaxing
09:49 AM Loetmichel: because of inhomogen heating
09:49 AM Loetmichel: (bubble heats up faster than the rest of the vial)
09:50 AM jesseg: right
09:50 AM jesseg: I suspect that
09:50 AM jesseg: probably over all increased pressure plus a super hot spot where the bubble was
09:50 AM Loetmichel: like the classic "freshly cleaned beer glass with thick bottom" that has said bottom fall out the moment you put cold beer in
09:51 AM Loetmichel: been there had that... including my dumb face
09:52 AM Loetmichel: and the wet feet ;)
09:52 AM Loetmichel: the friends at the hobby bar literally went ROTFL when they saw my "WTF" look
09:56 AM jesseg: lol
10:14 AM Jymmm: Loetmichel: Hot Beer + Cold Mug???
10:15 AM Loetmichel: Jymmm: mug fresh from the dish washer, thick bottom glass still at about 80°C... and 8°C beer :-)
10:16 AM Loetmichel: https://images-na.ssl-images-amazon.com/images/I/41ZdgPIGSyL.jpg <- THAT kind of mug
10:16 AM Loetmichel: the thick bottom holds temperature quite well...
10:16 AM Loetmichel: the bottom fell clean off
10:16 AM Loetmichel: :-)
10:16 AM Loetmichel: AFTER i filled it of course
10:19 AM Jymmm: Loetmichel: Again, why would you put COLD beer into a HOT glass????????
10:20 AM Loetmichel: I didnt notice that the bottom still was hot
10:20 AM Loetmichel: the handle was already at room temp
10:20 AM Jymmm: Loetmichel: Ah, gotcha
10:20 AM Jymmm: Loetmichel: Don't you frig/freeze your mugs, to keep the beer cold?
10:20 AM Loetmichel: no
10:21 AM Loetmichel: we had a "feed thru" beer cooler in the living room back then
10:21 AM Jymmm: Loetmichel: WHY DA HELL NOT?! you LIKE warm beer?
10:21 AM Loetmichel: and the glasses itself usually didnt last long enough to warm up ;)
10:21 AM Jymmm: hahaha
10:21 AM Loetmichel: the contents i mean
10:22 AM Loetmichel: thats why i know the beer was exaclty 8 °C ;)
10:22 AM Jymmm: Fair enough =)
10:22 AM Loetmichel: it was an "all men" shared flat ;)
10:23 AM Jymmm: Loetmichel: Oh, you know your swimming pool heater???
10:23 AM Loetmichel: yes?
10:23 AM Jymmm: Loetmichel: I found a replacement for you, no pump needed =)
10:23 AM Loetmichel: hmm?
10:23 AM Jymmm: Gimme a moment..
10:24 AM Loetmichel: s/men/young guys
10:24 AM Jymmm: Loetmichel: It's long, but you can FF... https://www.youtube.com/watch?v=PBI4LaeKxDE
10:25 AM Jymmm: Loetmichel: Better... https://youtu.be/PBI4LaeKxDE?t=2783
10:26 AM Jymmm: Loetmichel: Betterer... https://youtu.be/PBI4LaeKxDE?t=3156
10:26 AM Loetmichel: Jymmm: WAY to much work to heat the pool
10:26 AM Jymmm: Loetmichel: just uses sticks and twigs
10:26 AM Loetmichel: that grill was already there, so was the copper tube and the garden hose and the pump... so it was cobbled together in less than 20 minutes
10:27 AM Loetmichel: it was a "instant" solution
10:27 AM Loetmichel: nothing so elaborated as a rocket stove
10:27 AM Jymmm: Loetmichel: I get it, just thought of you when I saw that video =)
10:27 AM Loetmichel: later in summer i used a 100m hard black plastic garden hose on the garage roof
10:27 AM Loetmichel: worked well, too
10:28 AM Loetmichel: instead of the grill
10:28 AM Jymmm: Loetmichel: Think wood fired hot tub
10:28 AM Loetmichel: yeah, those usually have the "rocket stove" submerged into the tub though
10:29 AM Loetmichel: have to go now, already nearly 30 minutes overtime... back in half an hour when i am at home ;)
10:29 AM Jymmm: Loetmichel: I'd have to see a pic of that.
11:14 AM Loetmichel: Jymmm: pic of what?
11:20 AM Jymmm: Loetmichel: "rocket stove" ___submerged___ into the tub
11:24 AM Loetmichel: Jymmm: i meant a stove that is built in a way that you can fire it from the top and thats submerged in the tub
11:24 AM Loetmichel: like in the "pure living for life" videos
12:02 PM SpeedEvil: https://www.youtube.com/watch?v=F871Uagu5wM&t=940s Another use for vice-grips.
12:14 PM Jymmm: SpeedEvil: best use ever =)
12:14 PM Jymmm: SpeedEvil: Especially right next to that steel rail =)
12:49 PM fragalot: SpeedEvil: lol
12:58 PM quqnuss: hello there :-)
01:00 PM quqnuss: pretty much a newbie and have got some questions.
01:03 PM gloops: fire away quqnuss, fire away
01:03 PM quqnuss: oh thanks .. :-)
01:04 PM quqnuss: so first of all, I have played around with lcnc and built a xyz and successfully ran it
01:05 PM gloops: excellent if youve got that far
01:05 PM quqnuss: now I am trying to make xyzab or xyzac ..
01:06 PM gloops: hmm 5 axis
01:07 PM quqnuss: sorry mate .. got to go .. sort of an emergency .. catch you guys later
01:07 PM quqnuss: thanks for encouraging replies ..
01:07 PM gloops: mate - either UK or Aus
01:08 PM fragalot: scared him off that quick eh
01:09 PM fragalot: might be a new record
01:09 PM fragalot: I found this old harddisk with photos from pre-2009 that I thought I'd lost forever
01:09 PM gloops: i couldnt have helped with 5 axis anyway lol, i was just being polite
01:09 PM fragalot: and it still works
01:09 PM fragalot: but the copying is only happening at 0.1Mb/s
01:09 PM fragalot: ... it's 800Gb.
01:10 PM fragalot: this may take a while :D
01:11 PM gloops: i bet the little sheets of paper on the interface are going from one side to the either really slowly lol
01:12 PM fragalot: time remaining: 104 days, 17 hours, 42 minutes
01:13 PM gloops: wonder if getright is still going
01:27 PM fragalot: ._. why is this so slow
01:37 PM fragalot: 0.03MiB/s
01:39 PM gloops: file system on the harddrive?
01:40 PM fragalot: seems to be NTFS
02:38 PM CaptHindsight: adding axises is like adding dimensions, you just keep folding
02:38 PM CaptHindsight: https://en.wikipedia.org/wiki/Flatland
02:42 PM gloops: carl sagans interpretation was ok
02:44 PM CaptHindsight: billions and billions
02:44 PM gloops: https://www.youtube.com/watch?v=UnURElCzGc0
02:45 PM CaptHindsight: I miss that guy
03:03 PM CaptHindsight: https://www.youtube.com/user/CarlSaganPortal/videos not many views
03:03 PM CaptHindsight: he's from before the intertubes
03:05 PM CaptHindsight: Carl Sagan - Cosmos - Eratosthenes vs The Odd Couple - Password https://www.youtube.com/watch?v=2_sFmt8xPY0
03:54 PM Deejay: gn8
05:26 PM jthornton: I drove a Honda Insight today and wow
05:27 PM Rab: Wow good, or wow bad?
05:27 PM jthornton: wow good
05:27 PM jthornton: the car drives itself
06:16 PM Tom_L: jthornton, does it talk to you as well?
06:17 PM Tom_L: GUI looks good btw...
06:21 PM Valen: is there an updated installer floating around? The linuxcnc website is pushing wheezy which was out of support may last year
06:26 PM CaptHindsight: there is, somebody posted the links here the other day
06:27 PM CaptHindsight: http://www.linuxcnc.org/testing-stretch-rtpreempt/ maybe this, let me see
06:28 PM CaptHindsight: https://github.com/LinuxCNC/linuxcnc/pull/500
06:29 PM CaptHindsight: Valen: ^^
06:30 PM Valen: CaptHindsight: thanks mate ;-)
06:30 PM CaptHindsight: no worries
06:31 PM Valen: friend was having issues as dropbox no longer supports the wheezy glibc version
06:32 PM Valen: I see some people reporting differeces in latency between rtai and preempt that much of an issue?
06:59 PM CaptHindsight: Valen: RTAI, well properly built RTAI is much faster than preempt_rt
07:00 PM CaptHindsight: rtai.org has been difficult for us to work with so we fork everything and build it ourselves
07:00 PM CaptHindsight: the LCNC devs don't have time for this so they skipped RTAI on this round
07:01 PM CaptHindsight: Valen: it's mostly an issue if you want to software step
07:01 PM Valen: that's what the friend wants to use it for
07:01 PM CaptHindsight: preempt_rt won't be fast enough for fast stepping
07:02 PM CaptHindsight: you won't know until you run the latency tests on the board he wants to use
07:02 PM CaptHindsight: some people have gotten <25uS with preempt_rt others are closer to 100K uS
07:03 PM CaptHindsight: sorry 100uS
07:03 PM CaptHindsight: some worse, some better
07:03 PM CaptHindsight: RTAI was usually good unless the board had a flaky BIOS
07:04 PM CaptHindsight: the RTAI dev here tried to work with RTAI.org but they didn't cooperate
07:06 PM CaptHindsight: and people don't want to pay for RTAI development so it has stalled out again
07:21 PM flyback: linuxcnc should include a micro os for small embedded cpu's
07:21 PM flyback: to use for each motor etc
07:21 PM flyback: wehen you need timing critical or safety-can-not-fuck-up-ever deadlocks
07:21 PM flyback: I agree 100 with linux still being the heart of the cnc and issuing commands etc
07:22 PM flyback: just the timing for iching along steppers etc might be better with a dedicated avr per stepper etc
07:23 PM flyback: or even linux on small embedded boards like that one mips baord for $5
07:23 PM flyback: don't think I am bashing linux saying it's not a good fit
07:23 PM flyback: not at all
07:24 PM norias: sounds reasonable, on it's face
07:24 PM flyback: just for picosecond timing such as a high speed servo or a laser cutter, might want a custom firmware instead of a full os for that piece and have linux then direct it
07:25 PM flyback: norias, what part of pa are you in
07:26 PM flyback: or wait we talked before didn't we?
07:26 PM norias: Pittsburgh
07:26 PM flyback: 45 mins from me :)
07:26 PM norias: cool
07:26 PM flyback: was at allagany general last wednsday all day
07:26 PM flyback: dad had heart surgery
07:26 PM norias: sorry to hear that
07:26 PM norias: i'm assuming it went well?
07:26 PM flyback: na he's good they fixed it
07:27 PM flyback: they burned out the defective nerve causing the afib
07:27 PM flyback: it's done
07:27 PM norias: good deal
07:28 PM norias: i'm really about 15 / 30 minutes north of the city
07:28 PM norias: depending on traffic
07:29 PM flyback: besides the fact my idea, they have so many cheap cpu's now it's rediculous
07:29 PM flyback: like arm cortex m0
07:29 PM flyback: some are no more than a few bucks etc
07:29 PM flyback: if you needed one piece of your cnc machine to be picsecond timed
07:30 PM flyback: it all just depends on what you are doing I guess
07:30 PM norias: i think it's a good point
07:30 PM norias: i'll keep it in mind when i get there
07:30 PM norias: i'm _slowly_ designing a horizontal cnc milling machine
07:30 PM flyback: nice
07:30 PM norias: like a mini HMC
07:31 PM norias: studying motors and motor controls, right now
07:31 PM flyback: I think even a crayon resolution cnc machine is still freaking awesome
07:31 PM norias: and sketching some base components to send to foundries for initial rough quotes
07:31 PM flyback: norias, don't forget some thermal fuses
07:32 PM flyback: and a big "fuckit" red button
07:32 PM norias: yeah, definitely an e-stop
07:32 PM flyback: themal fuses are like fuses but they melt due to temp not current
07:32 PM norias: i basically want to shrink a modern HMC down to desktop size
07:32 PM flyback: espically if you use any induction motors which self light when stalled rather quickly
07:32 PM norias: i'll likely use some version of linuxcnc for the controller
07:32 PM flyback: most fans etc have a thermal fuse inside the winding
07:33 PM norias: uh, i might avoid induction motors
07:33 PM norias: not sure yet
07:33 PM flyback: for when the bearing wears out and they lockup
07:33 PM flyback: it melts and cuts the power forever
07:33 PM flyback: prevent house fires
07:33 PM norias: i want to compete on size and cost with the tormach
07:33 PM flyback: they are cheap
07:33 PM flyback: pennies I think
07:33 PM flyback: in hair dryers, ovens etc
07:33 PM norias: i _think_ i need to run on 110 single to do so
07:33 PM norias: therfore induction might not be a good idea
07:33 PM flyback: please consider some
07:34 PM norias: i will, thanks
07:34 PM flyback: well induction are a cunt to speed control cheap
07:34 PM flyback: you need vfd which is not cheap
07:35 PM norias: i plan on about 1/3rd of bom cost being electronics of some sort
07:35 PM norias: i might just make it for myself, if no one likes it when i'm done
07:35 PM norias: i'm thinking about finding some dumb commodities that can be milled
07:36 PM norias: and making those to make some cash
07:36 PM norias: motor mounts or standardish brackets
07:37 PM CaptHindsight: flyback: how about UEFI for the micro OS, then it could run out of band on your PC and you wouldn't even know it!
07:38 PM CaptHindsight: then when you realize that a micro OS needs all sorts of drivers to support well everything in a PC then it's not a micro OS
07:39 PM flyback: well the micro os would be for a cpu not capable of running a full os
07:39 PM flyback: not on a pc
07:39 PM flyback: pc should just use linux
07:39 PM flyback: im saying if you use a avr to drive each stepper
07:39 PM flyback: then linuxcnc to talk to the avr's
07:39 PM CaptHindsight: so a different CNC application that is not LCNC
07:39 PM Tom_L: those are available already
07:39 PM flyback: well not a full application that is not linuxcnc
07:40 PM flyback: im saying just for each motor that needs very fast timing that not normal os will do well at
07:40 PM flyback: like for moving a high watt laser
07:40 PM CaptHindsight: https://en.wikipedia.org/wiki/Comparison_of_real-time_operating_systems
07:40 PM CaptHindsight: flyback take your pic for a RTOS ^^
07:40 PM flyback: just for moving the laser head around
07:40 PM flyback: linuxcnc tells the whole fixture where to go
07:40 PM flyback: where the whole head goes
07:41 PM flyback: but for "check sensor, turn on laser pulse, check sensor, turn on laser pulse"
07:41 PM flyback: might be good to have a small cpu with a rtos
07:41 PM flyback: ugh I suck at explaining what I mean
07:41 PM CaptHindsight: good for whom?
07:42 PM CaptHindsight: I understand what you are saying just fine
07:42 PM CaptHindsight: i just want you to use your noggin a bit harder
07:42 PM CaptHindsight: and think it through
07:42 PM flyback: I am
07:43 PM flyback: it
07:43 PM flyback: is not even a os
07:43 PM flyback: it's just firmware for that one cricital element piece
07:43 PM CaptHindsight: so spaghetti code CNC controller, see reprap
07:44 PM CaptHindsight: with the most dyslexic firmware i have ever seen
07:44 PM flyback: nevermind
07:44 PM flyback: bmcc
07:45 PM CaptHindsight: too bad the machinekit devs choose a poor SBC for their first target
07:46 PM CaptHindsight: flyback: the proble is the lack of cooperation by those with the skills, those with the skills tend to not have the time required
07:47 PM CaptHindsight: so you end up with all the half assed CNC controls
07:49 PM CaptHindsight: http://marlinfw.org/
07:51 PM Valen: flyback: I think you've just described mesa boards?
07:52 PM Valen: mesa have a step driver in their setup don't they?
07:52 PM CaptHindsight: cannuck yourself
07:52 PM flyback: yeah a daugther board
07:53 PM Valen: That'd do the job, and they are off the shelf and cheap enough in their low end one
07:54 PM Valen: hows the integration with the linuxcnc setup gui stuff these days?
07:54 PM flyback: or these motion controller they mention for linuxcnc supported
07:54 PM flyback: that's all I mean
07:54 PM Valen: nah afaik you don't use motion control with mesa and linuxcnc
07:54 PM Valen: lcnc does the motion control, the mesa just spits out step pulses at a rate
07:55 PM Valen: (altering the step rate in the servo thread)
07:55 PM flyback: yeah exactely what I was saying
07:55 PM flyback: but since there's already stuff for doing that then my idea is redudant
07:55 PM flyback: thx Valen much :)
07:56 PM flyback: all I was trying to say was if there wasn't already some kind of mesa board it might be a fun project to make a small os or firmware just for those boards
07:56 PM flyback: not needed I guess :)
07:56 PM flyback: as a linuxcnc offshoot
07:57 PM flyback: not needed, already been done
07:58 PM CaptHindsight: mesa has a stand alone motion controller already
07:58 PM CaptHindsight: it doesn't work with LCNC
07:58 PM flyback: oh
07:58 PM CaptHindsight: forget what he calls it
07:59 PM * flyback upgrades sherlock's kernel
07:59 PM CaptHindsight: SOFTDMC
07:59 PM flyback: my poweredge 1800 I rebuilt and turned into a dedicated data recovery and archival box
07:59 PM CaptHindsight: http://www.mesanet.com/pdf/motion/softdmc.pdf
08:01 PM CaptHindsight: reprap/makers get all freaked about by mesa cards
08:01 PM CaptHindsight: i guess they are supposed to be on sale for less than the cost of manufacturing them
08:01 PM Valen: they cost money, and they used to start out costing actual money
08:02 PM Valen: people are used to cheap crap from china
08:02 PM CaptHindsight: I seen people spend 100+ hours to use some $20 cheaper FPGA card
08:02 PM CaptHindsight: so i guess their time is work 2 cents per hour (US)
08:02 PM Valen: I can see people wanting/using some kind of arm / serial usb thing they can build it themselves for a few $
08:03 PM Valen: but the base model mesa card is like $50 isnt it?
08:04 PM Valen: $90
08:04 PM rmu: if you want something cheap you can port something like this https://github.com/kinsamanka/PICnc-V2 to a €15 nucleo board
08:05 PM rmu: and plug it into a raspberry pi
08:05 PM rmu: takes about a weekend
08:05 PM Valen: machinekit is some variant of lcnc isnt it?
08:06 PM CaptHindsight: yeah fork
08:06 PM CaptHindsight: BBB turd board
08:06 PM CaptHindsight: turd i meant TI
08:07 PM CaptHindsight: the part people tend to leave out: no GUI
08:12 PM flyback: yeah rpi would be fine also
08:12 PM flyback: in fact the pi0's would be perfect
08:13 PM flyback: you can run linuxcnc on both, just config the rpi one to be stripped and very timing critical
08:13 PM flyback: and one big linux cnc to drive them all
08:14 PM rmu: you need some external hardware to generate the pulses for steppers. timing on the pi is not accurate and not stable enough
08:15 PM rmu: (the GPU can and does change clocks at will without the CPU noticing)
08:16 PM CaptHindsight: and it's Broadcomm
08:18 PM rmu: broadcom = unfriendly company. no real docs. available docs are inaccurate and incomplete. parts of the pi design just suck and did need 3 iterations to work better than "somewhat".
09:11 PM flyback: broadcom > imagination technologies
09:12 PM flyback: they were so nda even m$ stopped working with them
09:12 PM flyback: they will be extinct soon enough
09:12 PM flyback: they already sold off mips
10:02 PM SpeedEvil: rmu: Parts of the Pi design needed 3 design iterations when the chief of the pi foundation was _SENIOR ASIC DESIGN MANAGMENT AT BROADCOM_
10:04 PM SpeedEvil: And simple basic, basic issues like not bringing out the second USB port on the B, even as a header, meaning everything has to share bandwidth with the NIC through a USB hub. (till recently at least)
