[02:57:59] <stillme> hello guys, please whats the difference between 60 deg v bit and 60 deg engraving bit ?
[02:59:06] <Valen> nothing i've heard of?
[03:00:35] <stillme> i noticed that when trying to generate preview in photovcarve, the result i get from 60deg vbit setting is better that of 60deg engraving bit, all other settings being same
[03:01:17] <stillme> so am thinking if i could use 60deg engraving bit i got even when the setting is 60deg vbit
[03:02:36] <stillme> i think their main difference is the maximum depth they can cut, that of vbit is more

[03:04:44] <stillme> i will appreciate any one correcting me if am wrong
[03:23:15] <mk0> RussianKid, :) ты откуда?
[03:23:23] <mk0> where are you from?
[03:42:41] <RussianKid> im from russia
[03:42:49] <RussianKid> all in the name
[04:12:41] <mk0> i'm too. moscow?
[04:13:35] <RussianKid> born in moscow, moved to england in 2000, lived there ever since. now at nottingham university, designed and now making a low gantry based CNC router to cut custom water cooling components for computers
[04:14:42] <RussianKid> switched to linuxCNC because it's better in every way, been reading this channel since
[04:19:55] <psha[work]> набижали
[04:20:10] <psha[work]> i mean glad to see forth one here
[04:27:08] <jonasthomas-> Hello everyone... I'm organizing an event called www.osmoces.org in wheaton il, on Sat Oct 13 2012. It's a cross pollinations event with High School Robotics Teacher/Students, Engineers and the open source Maker community. I was hoping to have some introductory sessions on Linuxcnc. I'm looking for someone who might have a small desktop mill that they could print to the event and...
[04:27:10] <jonasthomas-> ...yak about it. I think I'm might have a few leads(Circ)... but I thought it might be worth asking here.
[04:28:27] <jonasthomas-> bring to the event.... (got 3d printers on the brain at the moment)
[04:57:00] <micges> jonasthomas-: hi
[04:57:53] <micges> can you post this on the emc mailing list?
[05:03:48] <archivist> RussianKid, you are only 30 miles ish from me then near Burton upon Trent
[06:13:52] <jthornton_> jonasthomas-, you might also try the mailing list and the forum
[06:24:42] <jthornton> anyone know if at_pid works?
[10:21:16] <timholum> I have a system that has muliple gpio pins, is there a way to configure linuxcnc to use the gpio pins directly to controll stepper's or to put the commands so a linistepper can controll it?
[10:33:56] <jdh> I know what all those words mean, but I have no idea what you mean.
[10:34:44] <jdh> I have a system with multiple gpio pins. I use linuxcnc to control steppers with them.
[10:35:27] <jdh> I guess "to control stepper drivers" would be less ambiguous and more correct.
[10:37:17] <JT-Shop> define 'system'
[10:37:57] <jdh> yeah, guess that's where I got lost.
[10:38:21] <jdh> I have a raspberry pi "system" with gpio pins
[10:38:22] <alex_joni> sounds like he wants to drive stepper windings directly from the GPIO's
[10:38:44] <alex_joni> linuxcnc might do that with stepgen output set to the needed phases
[10:38:54] <alex_joni> but you still need an amplifier on each IO
[10:39:47] <JT-Shop> hi alex_joni
[10:41:05] <alex_joni> hi JT-Shop
[10:46:42] <archivist> timholum, see the stepgen docs types 5 and up
[10:47:33] <timholum> archivist: thanks I figured it would be something easy, I just could not figure out where to look
[10:48:51] <archivist> timholum, but that is not the best way to go probably, a current limiting driver being better
[10:50:01] <timholum> archivist: would that be like a linistepper?
[10:51:13] <archivist> timholum, sort of but a bipolar driver is even better
[10:52:30] <archivist> and I see that linistepper has issues at higher currents
[10:54:09] <archivist> 99% use switching to reduce heat in the driver
[10:57:47] <timholum> I already have 3 unipolar steppers, and to get it working off the bat I am trying to get my device running as cheap as possible, then upgrade to better steppers and controllers at that time
[10:58:23] <jdh> how big are your steppers?
[10:58:33] <Jymmm> JT-Shop: Just foud out that SS shim stock CAN be stacked and waterjet, sheet stock not so much.
[10:58:35] <archivist> what are you building
[11:06:56] <timholum> the steppers are 3.95v 6.1A, we bought a cncmill for $500, that the controller went out in
[11:07:27] <timholum> http://www.laxig.com/forums/topic/cnc-mill-conversion/ is the info about it
[11:07:40] <skunkworks> timholum, !!
[11:07:56] <skunkworks> I am sam from the lclug list
[11:08:02] <archivist> that linistepper will struggle at 6A
[11:08:13] <timholum> Hows it going :)
[11:08:16] <skunkworks> (with the big Kearney and trecker mill converted to linuxcnc)
[11:08:27] <Jymmm> Son of Sam is more like it!
[11:08:42] <skunkworks> exactly.. (my dads name is sam..)
[11:08:53] <Jymmm> =)
[11:09:00] <skunkworks> creepy
[11:09:20] <syyl_ws_> my shop smells like a carpentry :(
[11:09:25] <skunkworks> this was a gorton mill converted to an AHHA control which died
[11:09:27] <jdh> 8 degree stepper?
[11:09:28] <syyl_ws_> machining wood paterns for casting
[11:09:41] <archivist> timholum, there is no way I would dream of using the linistepper on that machine
[11:10:00] <syyl_ws_> that will take days to clean the wood dust off the machines
[11:10:50] <skunkworks> timholum, what drives are on the machine?
[11:11:13] <archivist> I bet the drives in the machine could be used
[11:11:28] <timholum> archivist: even if I upped the mosfet's to larger capacity one's? skunkworks: http://laxig.org/tholum/Picture/stepper.jpg
[11:12:22] <Jymmm> timholum: What motor DRIVERS do you have?
[11:12:29] <Jymmm> or it came with
[11:12:38] <timholum> Jymmm: none
[11:12:43] <archivist> look in the old control box for the drivers and power supply
[11:12:56] <Jymmm> timholum: It came with ZERO electronics at all?
[11:12:59] <timholum> unfortunatly they through the controller away, yes
[11:13:09] <skunkworks> aww - yeck
[11:13:21] <timholum> brb
[11:13:26] <Jymmm> timholum: So, the motors only came with bare wires?
[11:13:45] <skunkworks> how many wire steppers are they (actually taking the back off) maybe they could be wired bipolar?
[11:14:12] <Jymmm> skunkworks: the pic says uni
[11:14:39] <archivist> even uni can be rewired bipolar
[11:14:51] <skunkworks> right - but some brought all the wires out so you could wire them bi-polar. (not commoned.)
[11:14:58] <archivist> 8 wire is trivial
[11:15:02] <skunkworks> yes
[11:16:40] <archivist> 6 wire is trivial serial connection , 5 wire you need to get in the motor to separate and get in the motor for 6 to wire parallel
[11:17:02] <skunkworks> right
[11:17:41] <skunkworks> we have taken some older inland steppers and cut the common to wire them bipolar.
[11:17:41] <archivist> getting in motors is fun :), just did my hobbing machine motor a bit ago
[11:18:01] <skunkworks> maybe not inland - slosyn
[11:18:03] <archivist> star to delta mod
[11:21:50] <jdh> I thought opening steppers pretty much destroyed them?
[11:22:06] <syyl_> only if you pull out the rotor
[11:23:17] <jdh> what is it that fails by removing/replacing the rotor?
[11:24:08] <syyl_> i am no expert, but i heard stuff like demagetising of the rotor if pulled out
[11:24:08] <archivist> magnets need keepers, they lose magnetism if kept open
[11:24:33] <syyl_> you can put a thin piece of sheetmetal (magnetic) between rotor and stator
[11:24:37] <syyl_> then nothing should happen
[11:24:50] <archivist> so pull into a steel ring
[11:25:26] <timholum> ok, im back, Jymmm: The steppers have plugs on them, but that is all
[11:25:36] <Jymmm> ok
[11:25:38] <archivist> but keeping it clean and free from metal filings is the hard part
[11:26:09] <syyl_> attracts everything that at least looks like steel? ;)
[11:26:41] <archivist> buggers to get off too
[11:27:08] <Jymmm> work in a glove box =)
[11:27:35] <syyl_> (trick to remove swarf from a magnet: plasticine)
[11:27:54] <syyl_> just work it over the swarf to remove..
[11:28:03] <Jymmm> http://www.air-testing-certifications.com/glove_box_dude.jpg
[11:28:09] <Jymmm> and a bunny suit too!
[11:28:28] <syyl_> that box could also be used for sandblasting ;)
[11:28:47] <Tom_itx> Jymmm his door is open
[11:29:01] <Jymmm> Tom_itx: TMI!!!
[11:30:01] <Tom_itx> i'm just saying...
[11:32:18] <Jymmm> lol
[11:33:55] <Jymmm> timholum: Just a random google search ... http://www.electronickits.com/kit/complete/motor/ck1405.htm
[11:36:23] <Jymmm> Some interesting reading about ZINC http://mysite.du.edu/~jcalvert/phys/zinc.htm
[11:39:45] <timholum> Jymm: interesting, I will have to do some looking for other ones ( my stepper requires 3.94 volts and that drives 8 to 35
[11:40:00] <timholum> but they may have other kits avalbile
[11:40:33] <Jymmm> timholum: Most stepper motors are driven at 20 to 25 times their rated voltage.
[11:40:34] <jdh> current regulated drives run steppers at much higher voltages than what they are rated for.
[11:41:47] <timholum> rilly? I did not know that :), That will make it much easyer to find a power supply, I thought I was going to have to design my own pwm voltage controller
[11:42:37] <timholum> so it would be ok for me to hook up a 12v or 15v powersupply to it?
[11:42:53] <jdh> to a current regulated driver, not directly to the coil.
[11:44:12] <timholum> So, not directy to my stepper then, but wont this controller put the voltage I give it to my stepper?
[11:44:37] <jdh> briefly
[11:46:20] <timholum> ok, :) so it is ok to run the steps with a higher voltage then,
[11:47:59] <archivist> timholum, the important thing is the current, you run higher voltage to improve switching time(inductance) and motor speed
[11:51:30] <timholum> ok, Good to know, I am pritty good with genral electronics, a bit with servos, but only the little 5v one's for basic stamp's and arduino's, but I have never actually made anything with steppers in it before so that is very good to know
[11:52:44] <jdh> I guess it obviously worked with 8-degree steppers, but a new 1.8 might be better.
[11:54:07] <timholum> jdh: I have plans on upgrading to some gecko motors latter on, but I just want to get it running as cheap as possible, mostly so if I fry something I am not out a new stepper or controller
[11:54:36] <timholum> and so after the upgrade I will have a few steppers and controller's lieing around for other projects
[11:58:35] <Jymmm> timholum: do your motors look like one of these? http://www.kollmorgen.com/uploadedImages/kollmorgencom/Products/Motors/Stepper/E_and_H_Hybrid/E_and_H_Hybrid_LARGE.jpg
[12:00:24] <timholum> simmalar to the larger one, here is an image of one http://laxig.org/tholum/Picture/stepper.jpg
[12:01:12] <Jymmm> timholum: that's not the whole motor and why I asked.
[12:02:11] <jdh> http://www.automationtechnologiesinc.com/products-page/nema-34/nema-34-high-torque-stepper-motor-1200-oz-in-half-inc-single-shaft-with-flat
[12:04:10] <timholum> http://laxig.org/tholum/Picture/stepper2.jpg
[12:05:18] <Jymmm> timholum: Ok, it seems that PN is still active at Dahner Motion (sp), but a PITA to find the datasheet.
[12:06:23] <Jymmm> SciPac was bought out by them
[12:06:34] <jdh> or PacSci
[12:06:46] <Jymmm> or both!
[12:06:48] <Jymmm> lol
[12:06:52] <Jymmm> jdh: ty
[12:08:31] <IchGuckLive> hi all
[12:10:47] <Jymmm> Tom_itx: Did you see these? http://www.kickstarter.com/projects/digistump/digispark-the-tiny-arduino-enabled-usb-dev-board
[12:13:47] <IchGuckLive> what is this mill bit called in english ? http://mechmo.de/fraeser_lang.jpg
[12:15:27] <jdh> Ich: double-ended ball nose?
[12:16:42] <IchGuckLive> it is
[12:17:29] <jdh> anyone used a MikroTik router/AP? http://routerboard.com/RB751G-2HnD
[12:18:19] <IchGuckLive> jdh: http://www.ebay.com/sch/i.html?_trksid=p5197.m570.l1313&_nkw=double-ended+ball+nose&_sacat=0
[12:18:34] <IchGuckLive> B) O.o
[12:18:45] <FinboySlick> jdh: I have a 450G here under my desk.
[12:18:53] <FinboySlick> jdh: But I put OpenWRT on it.
[12:19:38] <jdh> cool, didn't know they would run wrt
[12:20:02] <FinboySlick> jdh: A lot of them don't. The 450G is still a bit of a hack.
[12:20:18] <jdh> nifty graphs and real time stats via the web interface in some of them.
[12:20:37] <IchGuckLive> 7/8 is this 22mm
[12:21:11] <FinboySlick> jdh: I'm pretty much sold on OpenWRT for al my embedded networking needs, but I was impressed with the DD-WRT install that comes with buffalo hardware.
[12:23:22] <FinboySlick> IchGuckLive: 22.225mm
[12:23:35] <IchGuckLive> :D
[12:23:37] <FinboySlick> So a tad oversized.
[12:23:44] <Jymmm> FinboySlick: jdh What's so special about THAT router?
[12:24:23] <jdh> never used one. The RouterOS looks nice though.
[12:24:40] <jdh> and cheap for the feature set
[12:24:40] <Jymmm> jdh: link to what you are seeing?
[12:25:38] <jdh> http://routerboard.com/products
[12:25:48] <IchGuckLive> someone knows toolmex in Masachusets
[12:26:11] <IchGuckLive> http://stores.ebay.com/Toolmex-Online-Outlet-Store?_trksid=p4340.l2563
[12:26:50] <jdh> http://www.mikrotik.com/software.html Try the Demo link at the bottom
[12:26:55] <Jymmm> jdh: Ummm http://www.streakwave.com/Itemdesc.asp?ic=RB751G-2HnD
[12:27:08] <jdh> yeah?
[12:27:18] <FinboySlick> Jymmm: It has some pretty solid specs ar 7xxx chips are fast.
[12:27:24] <Jymmm> I dont know, is that the same thing?
[12:27:41] <jdh> it is one of their products
[12:28:30] <IchGuckLive> antennas built in is not good
[12:29:21] <FinboySlick> IchGuckLive: Well, you put computer systems in metal casings, obviously it isn't for you ;)
[12:29:33] <Jymmm> jdh: sure, but is it the SAME but with an enclosure?
[12:29:33] <jdh> depends on the application. They can have remote antenna though
[12:29:51] <jdh> they sell it with/without an enclosure
[12:30:19] <FinboySlick> jdh: If you want ar7xxx and a good price, I'd look at buffalo hardware instead.
[12:30:30] <IchGuckLive> FinboySlick: i use speedport AP
[12:31:21] <Jymmm> why does it say "license" ?
[12:31:42] <FinboySlick> Jymmm: microtik os is not open source.
[12:31:51] <Jymmm> ah
[12:32:01] <IchGuckLive> FinboySlick: http://router-faq.de/anschluss/Speedport_W_723V_Typ_A.png it also connects the DECT telefones for the house
[12:32:28] <jdh> I've been disappointed with every consumer AP/etc I've bought.
[12:32:32] <FinboySlick> IchGuckLive: That's pretty funky.
[12:32:51] <FinboySlick> jdh: Heh, did you put openwrt on 'em?
[12:33:00] <jdh> not in years.
[12:33:14] <FinboySlick> I run a pbx on my 5 year old linksys router.
[12:33:15] <IchGuckLive> FinboySlick: in germany we got almost 16.000k 16Mbit in all houses
[12:33:43] <IchGuckLive> as the TV coes also throu IP
[12:34:07] <FinboySlick> IchGuckLive: Yeah, but your money also goes through the european central bank.
[12:34:16] <IchGuckLive> BAD
[12:34:23] <FinboySlick> Hehe.
[12:34:28] <FinboySlick> So stop bragging ;)
[12:34:40] <IchGuckLive> Greek will pull all the stuff
[12:35:02] <FinboySlick> The whole thing is a ponzie scheme, greece is just the fall guy.
[12:35:48] <IchGuckLive> as you say
[12:36:22] <FinboySlick> Honestly, it's no better in america.
[12:36:54] <IchGuckLive> 5GB lan is this new i only thought about 1GB
[12:37:15] <FinboySlick> IchGuckLive: I think they mean 5x1GB as in 5 ports.
[12:37:45] <IchGuckLive> oh
[12:38:23] <IchGuckLive> my dish satreciver does a download to the pc with 500Mbit max
[12:38:36] <IchGuckLive> i never got higher
[12:38:52] <FinboySlick> IchGuckLive: You're limited by the packet size.
[12:38:58] <IchGuckLive> MS to ubunto only at 250Mbit
[12:39:16] <FinboySlick> IchGuckLive: To hit 1Gbit, you will need jumbo frames.
[12:39:42] <FinboySlick> (typically)
[12:39:52] <IchGuckLive> packet size is choosable higher is faster ?
[12:40:16] <FinboySlick> IchGuckLive: For bulk transfer it will be. Some things just don't really fit into larger packets.
[12:40:29] <FinboySlick> Typically, you set the MTU.
[12:41:06] <FinboySlick> For example, voip won't gain from jumbo frames.
[12:41:08] <IchGuckLive> i figured out that the HP printer in the lan did reduse the speed
[12:41:16] <IchGuckLive> i changed to a Kyocera
[12:41:30] <FinboySlick> IchGuckLive: If you use a switch, it shouldn't have an impact.
[12:41:30] <IchGuckLive> now im up 10times
[12:41:50] <IchGuckLive> 1GB switch is in
[12:42:12] <IchGuckLive> maybe i shoudt also check without DHCP
[12:42:15] <FinboySlick> Then I don't know how your printer could slow transfer between hosts.
[12:42:41] <FinboySlick> IchGuckLive: dhcp won't have an influence either.
[12:43:10] <FinboySlick> You're in europe though, maybe your government wants a copy of every packet that goes through your LAN for security purposes ;)
[12:43:21] <IchGuckLive> maybe the Switch is in 4x4 sectors and it got brighes in between
[12:43:21] <FinboySlick> that might slow youd own
[12:43:38] <jdh> NSA does wirespeed packet copying here.
[12:43:40] <FinboySlick> IchGuckLive: What are the bridges?
[12:44:24] <IchGuckLive> the printing on the switch is at groups of 4 4 switches
[12:44:34] <FinboySlick> jdh: I've actually met a telco installer who put that stuff in.
[12:44:46] <FinboySlick> jdh: It's pretty darn scary.
[12:44:54] <IchGuckLive> Group0 lan0...lan3 group1...
[12:45:06] <FinboySlick> IchGuckLive: Are you talking about vlans?
[12:45:24] <IchGuckLive> i dont know i only pluged it
[12:45:38] <FinboySlick> Seems a bit odd to me.
[12:45:57] <FinboySlick> So you have 4 switches all connected together via one of their ethernet ports?
[12:46:02] <IchGuckLive> ok it is fast enoph for the TV to bring the movies to the pc or in the other direction
[12:46:38] <FinboySlick> If you get odd speeds, you might have created a loop in the topology.
[12:47:01] <IchGuckLive> FinboySlick: no it has just 16 connectors at the back
[12:47:30] <FinboySlick> IchGuckLive: Ok, so it's a 16 port switch, no other switch?
[12:47:50] <IchGuckLive> no only this
[12:48:12] <IchGuckLive> etch pc,sat,printer,tv got its own cable
[12:48:22] <FinboySlick> OK, that's fine.
[12:48:29] <IchGuckLive> one DHCP AP also in
[12:50:17] <FinboySlick> IchGuckLive: A switch will not slow down because a slower device is plugged to one of its ports.
[12:50:35] <FinboySlick> So I'm still wondering why changing your printer improved performance.
[12:51:15] <FinboySlick> With TCP, you could be falling victim of the flow-control issue.
[12:51:47] <FinboySlick> Typically you want to disable flow control on your switch ports.
[12:52:21] <IchGuckLive> ok i will go after this issue
[12:52:37] <FinboySlick> IchGuckLive: Is it a managed switch?
[12:52:48] <IchGuckLive> dont kow
[12:53:06] <FinboySlick> What model is it?
[12:54:15] <IchGuckLive> Allnet ALL8816V2 / 16 Port Gigabit Switch
[12:55:36] <FinboySlick> That's an unmanaged switch, so it won't really let you decide if it handles flow control or not.
[12:55:46] <Connor> jdh I use Mikrotik stuff! :)
[12:56:15] <FinboySlick> Connor: You have to use OpenWRT stuff instead.
[12:56:35] <Connor> Umm Why ?
[12:56:48] <FinboySlick> Connor: Because open source.
[12:56:53] <FinboySlick> So there.
[12:57:16] <FinboySlick> Nop. No arguing.
[12:57:34] <Connor> Umm. No. MikroTik is a bit more mature than OpenWRT.. I've been using it for 8 years now?
[12:58:09] <FinboySlick> Heresy!
[12:59:01] <Connor> Normally, I'm all for Open Source.. but, in the case, Having used both, and now the capabilities of both.. I choose MikoTik. Nuff Said. :)
[13:04:31] <Thetawaves> thanks for showing mikrotik
[13:04:32] <Thetawaves> shit looks awesome
[13:04:44] <Connor> so, what are we talking about with regards to MikroTik and OpenWRT and the routerboards ?
[13:07:04] <jdh> O
[13:07:25] <jdh> I'm looking for a better router/ap/etc device.
[13:07:32] <Connor> jdh: I used MT stuff all the time when I was Sysadmin for ISP.
[13:07:55] <Connor> I'm currently using on for my home router, have 1 at my datacenter, client using 2 of them.
[13:08:19] <Connor> different models.. but.. all running MT OS.
[13:08:57] <jdh> the best place for the router is not a good place for an AP
[13:09:21] <Connor> I even built a Enterprise class firewall out of a P4 with 2 x 4 Ethernet cards running the MT OS on a IDE DOM
[13:09:45] <Connor> http://www.roc-noc.com/
[13:10:15] <Connor> OH. You mean for installation..
[13:11:10] <jdh> yeah. External antenna would probably fix that, but that doubles the price.
[13:11:28] <Connor> No it don't.
[13:11:28] <Connor> just depends on the model.
[13:11:28] <jdh> so, what MikroTik for a normal house
[13:13:18] <Connor> Look for one with the RB433L board.
[13:13:31] <Connor> Cheaper board, has 3 mini-pci slot
[13:14:02] <Connor> how man ethernet ports you need ?
[13:14:35] <jdh> 4 or 5. I have 4 + a switch now
[13:15:03] <Connor> most of these either have 1 or 3 till you get into the more expensive ones, or ones without wifi
[13:15:46] <jdh> http://www.roc-noc.com/product.php?productid=446&cat=&bestseller=Y
[13:15:58] <jdh> can you just plug one of those in a switch port?
[13:16:16] <Connor> not that one. It's USB
[13:16:16] <jdh> err, not that, one of the ethernet ones.
[13:17:15] <Connor> you have a machine not able to get to the wifi ?
[13:18:03] <jdh> yes. The only good place for the wan+ethernet to reach is not a great place.
[13:18:04] <Connor> might be easier / cheaper to just hang a AP off one of your Ethernet ports were it can give access to everythnig.
[13:19:43] <jdh> these all seem to be 2.4ghz only
[13:20:42] <Connor> I personally just configure my own..
[13:20:54] <jdh> your own what
[13:21:12] <Connor> On the ones that have the mini-pci slots.. you can specify what radio cards you want in them.
[13:21:17] <jdh> oh
[13:24:37] <Connor> the R52 79mw radio is a/b/g
[13:25:18] <Connor> R52H is the same one, just 350mw.
[13:25:23] <Connor> might be better choice.
[13:25:37] <Connor> http://www.roc-noc.com/mikrotik/routerboard/rb411-complete.html
[13:25:46] <jdh> so only one needed?
[13:25:58] <Connor> Are you doing 5gz ?
[13:27:00] <jdh> how do you have a 1 port router.
[13:27:03] <Connor> OH. and you need Level 4 OS license for a AP
[13:27:23] <Connor> It's not a router, it would be a Access Point, or Client
[13:27:50] <jdh> Mikrotik RouterBoard RB/411AR RB411AR complete 1 port 10/100 router assembled with indoor case
[13:27:55] <Jymmm> 24GHz FTW!!!
[13:27:58] <jdh> it says it is a router
[13:29:03] <jdh> this is the point I usually say fuckit and go get another PoS consumer device from the store.
[13:29:27] <Jymmm> jdh: lather rinse repeat
[13:30:10] <Jymmm> jdh: this didnt look bad http://www.streakwave.com/Itemdesc.asp?ic=RB751G-2HnD
[13:30:42] <Connor> Well, 1 single port ethernet + 1 wifi can be a router. You could use VLAN and a vlan capable switch.
[13:31:09] <Connor> Jymmm: No external atenna
[13:31:14] <jdh> so, $166 for that, then $xxx for the switch
[13:31:25] <Jymmm> Connor: has jack for one if you read description
[13:31:57] <Connor> jdh: That's why I was asking... Leave your existing router like it is, and hang a AP off in a better location
[13:32:15] <Connor> All-in-one not always the best solution. :)
[13:32:28] <Jymmm> jdh: why a new one? broken? extended coverage?
[13:32:37] <jdh> Connor: I dislike the router portion of my existing one also.
[13:32:42] <Connor> ok
[13:33:20] <jdh> If it didn't involve crawling under my house, I'd just run ethernet to someplace better and hang a WAP there.

[13:36:49] <andypugh-iPhone> Sat outside a bar on the coast of Italy, watching girls in bikinis walk past. You think I am going to look at YouTube?
[13:37:14] <Connor> thats the same one Jymmm was show in streakwave.. Does have a MMCX connector for a external antenna
[13:37:24] <andypugh-iPhone> Oh, and I am being paid to be here:-)
[13:37:30] <Jymmm> andypugh-iPhone: yes
[13:37:31] <Connor> I've never used it.
[13:37:39] <Jymmm> andypugh-iPhone: you are too much of a geek not to
[13:42:34] <andypugh-iPhone> Jymmm: I didn't need to see videos of a mug about a game I still sometimes play.
[13:42:52] <Jymmm> hahahahaha
[13:44:21] <andypugh-iPhone> It's still a good game, it has the sort of gameplay that only a hyper-focussed 15 year old can create.
[14:28:41] <Tom_itx> Jymmm that board is probably a atmega8u2 which is pretty small for anything
[14:39:53] <Jymmm> Tom_itx: Sure, but one-off dedicated and cheap enough to leave in and not have to design/make your own pcb
[14:43:34] <Jymmm> Is there a large/jumbo/industrial version of an "automatic hand punch"? something with a little more umph?
[14:46:03] <mrsun> hydraulic press? :P
[14:50:40] <tjb1> Hey Jymmm, im about a week from starting :)
[15:13:48] <jp_> just made my first extruder hotend and it works!!!!
[15:14:50] <Tom_itx> Jymmm it's called a jack hammer
[15:22:30] <Jymmm> Tom_itx: Nope, that would cause multiple impacts
[15:22:39] <Jymmm> mrsun: Man-u-al =)
[15:23:13] <Jymmm> mrsun: just automatic manual =)
[15:23:57] <syyl_ws_> automatic hand punch?
[15:24:04] <syyl_ws_> you mean those automatic centre punches?
[15:24:18] <Jymmm> syyl_ws_: yeah, just industrial impact version
[15:24:21] <syyl_ws_> mh
[15:24:26] <syyl_ws_> try a crossbow ;)
[15:24:36] <syyl_ws_> na, i dont think there is something like that
[15:24:36] <Jymmm> syyl_ws_: impact, not force =)
[15:24:54] <syyl_ws_> what do you want to do?
[15:24:57] <Jymmm> there is, but too fscking expensive
[15:25:07] <Jymmm> syyl_ws_: steel stamp
[15:25:24] <syyl_ws_> why not use a press with depth stop?
[15:25:35] <Jymmm> syyl_ws_: impact, not force
[15:26:05] <syyl_ws_> steel is stamped all around the world with force ;)
[15:26:09] <syyl_ws_> use the force, luke!
[15:26:18] <Jymmm> have you ever used a hand stamp with a hammer before?
[15:26:43] <syyl_ws_> a letter/number stamp?
[15:26:45] <syyl_ws_> of course
[15:26:46] <Jymmm> yes
[15:26:53] <syyl_ws_> and it can be done with a press too
[15:26:55] <syyl_ws_> no problem
[15:26:59] <syyl_ws_> want a video? ;)
[15:27:03] <Jymmm> sure
[15:27:37] <syyl_ws_> do i realy need to take out one of my presses now? ;)
[15:28:05] <Jymmm> syyl_ws_: sure, use expllosives for best effect
[15:28:22] <syyl_ws_> i just cant see the problem
[15:28:32] <syyl_ws_> with a press its even very repeatable
[15:28:43] <skunkworks_> didn't they use explosives in old forming presses?
[15:28:48] <skunkworks_> :)
[15:29:26] <syyl_ws_> there is still a process called explosive forming :D
[15:29:37] <syyl_ws_> every shop should have explosives..
[15:30:16] <Jymmm> syyl_ws_: Sure, in SOFT material... http://www.youtube.com/watch?v=lZbs001XZ8g
[15:30:23] <skunkworks_> http://www.cnczone.com/forums/benchtop_machines/160220-emc2_gecko_g540_red_led.html
[15:30:48] <skunkworks_> I must have setup skunworks and don't remember... THen one day randomly I logged in as skunkworks and didn't even notice
[15:31:01] <syyl_ws_> mild steel works, Jymmm
[15:31:13] <syyl_ws_> at least with my small press
[15:31:25] <syyl_ws_> never tried toolsteel
[15:32:47] <Jymmm> syyl_ws_: This is what I'm talking about, the 1/2ton starts at $1400 http://www.youtube.com/watch?feature=player_embedded&v=T5g1XV2Sx6s
[15:34:39] <Jymmm> 3 ton $2000
[15:36:23] <syyl_ws_> haha, that even sounds like a automatic centre punch
[15:36:34] <syyl_ws_> but i am sure the same can be achieved with such a press
[15:36:34] <syyl_ws_> https://dl.dropbox.com/u/24396704/pub/2011-04-12_18-45-56_958.jpg
[15:36:38] <Jymmm> it's a glorified automatic hand punch in a drill press holder
[15:36:40] <JT-Shop> same but different I'd bet
[15:38:14] <Jymmm> 6 ton $5300
[15:39:16] <Jymmm> http://www.infinitystamps.com/images/ecom/presses/hirez/pryor_press_a1.jpg
[15:46:44] <Jymmm> They call them "Manual Impact Presses"
[15:48:21] <syyl_ws_> time to close the shop for tonight
[15:51:03] <Tom_itx> Jymmm use a hilti gun
[15:51:11] <Tom_itx> single shot
[15:51:17] <Jymmm> Tom_itx: Does it take .22LR ?
[15:51:27] <Tom_itx> some do
[15:51:30] <Jymmm> JT-Shop: syyl_ Tom_itx http://i48.tinypic.com/25zj7gl.jpg
[15:51:32] <Tom_itx> some are a bit bigger i think
[15:51:46] <skunkworks_> pcw_home, http://www.cnczone.com/forums/servo_motors_drives/159994-servo_advice_needed.html
[15:51:53] <Tom_itx> mine is a .22
[15:52:03] <Jymmm> Tom_itx: Heh, I just found out that pelets guns are illegal due to the NOISE they create.
[15:52:16] <Jymmm> no noise, then legal.
[15:52:17] <Tom_itx> pfft
[15:52:29] <Tom_itx> cover their head with a pillow first
[15:52:37] <Jymmm> lol
[15:52:57] <Jymmm> well, there's an exploded view of one
[15:53:06] <Tom_itx> arbor press
[15:53:21] <Jymmm> Tom_itx: impact, not force
[15:53:37] <Tom_itx> oh
[15:53:50] <Tom_itx> i've never used one of those
[15:53:56] <Tom_itx> i'd rather smack it with a big hammer
[15:53:57] <Jymmm> see the video?
[15:54:01] <Tom_itx> nope
[15:54:06] <Jymmm> scroll up
[15:54:50] <Jymmm> 1/2 ton veriosn is $1400. 3 ton $2000, 6 ton $5000
[15:54:51] <Tom_itx> there was a hammer press where i worked once
[15:54:58] <Tom_itx> huge flywheel
[15:55:20] <Tom_itx> probably upwards of 50 ton
[15:55:54] <Tom_itx> that thing works the same as my little centerpunch
[15:56:01] <Jymmm> yep
[15:56:08] <Tom_itx> are you gonna stamp parts out with it?
[15:56:09] <Tom_itx> ss
[15:56:10] <Tom_itx> ?
[15:56:18] <Jymmm> thats why I can't see paying $2000
[15:56:19] <Jymmm> yes
[15:56:24] <Tom_itx> make one
[15:56:25] <Jymmm> stamping ss
[15:56:28] <Jymmm> DUH!
[15:56:36] <Tom_itx> jt will fix u right up
[15:56:50] <Jymmm> I bet he will
[15:56:50] <Tom_itx> i told you to make a die
[15:57:18] <Tom_itx> get some valve springs from a semi
[15:57:24] <Tom_itx> and make one
[15:57:24] <Jymmm> die is for cutting, not marking
[15:58:02] <Jymmm> this impact press is for marking purposes, not cutting
[15:59:15] <Jymmm> Tom_itx: thats what I was thinking
[15:59:48] <Jymmm> funny thing that exploded diagram is far more complicated than my automatic centerpunch too
[16:00:20] <Tom_itx> just use a hydraulic cylinder for what you want
[16:01:07] <Jymmm> No, what I want is one of those I can chuck up in my drill press.
[16:01:26] <Tom_itx> beat the thrust bearing to hell
[16:01:44] <Jymmm> eh, I think it was out of the box
[16:01:50] <Jymmm> craftsman
[16:02:00] <Jymmm> (ryoby)
[16:02:34] <Jymmm> or find a dead one off craigslist
[16:21:47] <DJ9DJ> gn8
[16:49:28] <r00t4rd3d> anyone shoot bow/arrow like indian?
[16:49:44] <r00t4rd3d> brush burn i guess they call it
[16:49:59] <r00t4rd3d> FUCK
[16:51:15] <r00t4rd3d> my forearm swelled up the size of a baseball in 30 seconds
[16:51:42] <r00t4rd3d> i thought i was gonna die
[16:51:56] <r00t4rd3d> assholes were laughing.
[16:52:10] * archivist giggles
[16:53:28] <r00t4rd3d> you shoot that shit?
[16:54:29] <r00t4rd3d> my buddies release was too big for me, couldnt reach the trigger so I was doing it indian style and slipped.
[16:57:15] <r00t4rd3d> like my 5th shot, rolled off my finger and dropped me to my knees.
[16:57:39] <r00t4rd3d> HAHAHHAHAHAHHA
[16:57:48] <r00t4rd3d> they were lucky i couldnt shoot that mother fucker again
[17:07:29] <FinboySlick> To europeans in here: What's that god-aweful stew that everybody in scotland thinks is good?
[17:07:55] <FinboySlick> I think it's boiled guts or something like that.
[17:13:51] <Tom_itx> you gonna make some?
[17:14:19] <Jymmm> hagis
[17:15:23] <Jymmm> FinboySlick: It's a savory pudding =) http://en.wikipedia.org/wiki/Haggis
[17:17:02] <Tom_itx> that looks worse than McDonalds
[17:17:43] <Jymmm> Uk has some funky ass definitions of "pudding"
[17:18:42] <Jymmm> not just haggis either, rice, christmas, yorkshire, etc
[18:30:42] <tom3p> Jymmm, consider WEDM for cutting stacked SS We used to make little packets with top and bottom clamping plates, and pop a hole thru the whole deal for the wire start hole.
[18:43:08] <MattyMatt> Jymm, what we call pudding, US calls food :) it's anything with added sugar
[18:43:41] <MattyMatt> except steak & kidney pudding. no sugar in that afaik
[18:44:05] <MattyMatt> that's a boiled pie
[18:46:04] <MattyMatt> and pudding is generic for dessert
[18:46:21] <MattyMatt> aka afters
[18:49:09] <MattyMatt> stodge & custard. it sticks to your ribs
[18:49:57] <MattyMatt> unfortunately also your coronary arteries
[19:02:50] <syyl_> hmm
[19:03:03] <syyl_> haggis looks a bit like a two week old roadkill...
[20:17:18] <Jymmm> MattyMatt: they're calling haggis a pudding too, hardly a dessert =)
[20:18:17] <Jymmm> MattyMatt: The yorkshire pudding I've had, wasn't sweet nor a desert, more of a "pan bread"
[20:38:18] <alex4nder> hey
[20:50:13] <Jymmm> 3lbs of bacon all cooked finally!
[20:52:54] <Jymmm> That should be enough for a blac sandwich =)
[20:55:33] <ds3> was 2.5lbs of it grease?
[20:56:07] <Jymmm> not sure, still too hot to drain
[20:56:57] <Jymmm> but bacon grease is good to cook beans/stews with
[20:57:28] <ds3> or make soap or use for tapping certain things
[20:57:46] <Jymmm> Bacon flavored CNC ?
[20:58:06] <Jymmm> There is a Bacon Martini
[20:58:37] <Jymmm> bacon ice cream, bacon milkshake, bacon soap
[20:58:45] <Jymmm> (no lye)
[20:59:50] <Jymmm> I still haven't figured out how they make soap without the lye burning you.
