01:48 GargantuaSauce the fact that it's 50 bucks and does wifi control and video telemetry, perhaps?
01:48 MrCurious1 8 hours video or 2 hours movement
01:48 MrCurious1 it begs to have a computer talk to it instead of android
01:50 GargantuaSauce yeah i imagine the protocol is pretty simple too
01:50 MrCurious1 worse case gut it, and install arm cpu + diff camera
01:50 GargantuaSauce well if you're gonna do that may as well just do it from scratch i think?
01:51 MrCurious1 well, try to reverse it first
06:36 GuShH_ holy crap r�hm live centers are spendy
06:37 GuShH_ I don't think a chinky one will do, I gotta find something better, but not that expensive.

08:14 skilz What would I need from this site to build a robot that I can write programs for and run via sd card?

08:24 WaldoPepper anyone here experienced using the ROS framework?
08:44 rue_bed application specific code is more optimal than os generic stuff
08:46 WaldoPepper but a good frameworks keeps you from inventing the wheel again and again and... ;-)
09:17 rue_more are you gonna write one peice of software that can run every robot you ever build without you ever having to code again?
09:24 rue_more a person should write libraries
09:24 rue_more or use libraries
09:25 rue_more definitly nobody should put an OS on an 8 bit 16Mips microcontroller for the sake of having a os on it
09:25 rue_more the arduino library is extensive
09:32 WaldoPepper Did I mention the platform...? ;-)
09:34 rue_more nope
09:34 rue_more does it have a P4 on it?
09:34 rue_more :) ?
09:37 rue_more wheeled?
09:38 rue_more is it for a completely virtual robot?
09:48 WaldoPepper Its an embedded PC, quite powerfull. We shoudl concentrate on writing the behavioral code, hence the framework...
09:51 GuShH_ awww both milling machines are gone it seems
09:51 GuShH_ bastards
09:51 GuShH_ now what.
09:51 WaldoPepper The singularity is coming.... ;-)
09:51 ShH_ w
09:55 GuShH_ ohh there's a big number 2 for not much more, but it's way too big
09:55 GuShH_ rue_more: check out this german made beast http://mla-s2-p.mlstatic.com/fresadora-universal-marca-krebs-alemana-9786-MLA20020365100_122013-F.jpg
09:56 GuShH_ I've never seen one with a second vertical column like that
09:57 GuShH_ good price, but way too big.
09:57 WaldoPepper you doing cnc or manual work?
09:57 GuShH_ the price of that dividing head with the chuck alone is half of what the entire machine costs, if it includes tooling the price is a very good deal
09:58 GuShH_ WaldoPepper: why?
09:59 MrCurious GuShH_: http://www.frys.com/product/7665567?site=sr:SEARCH:MAIN_RSLT_PG
09:59 GuShH_ if you were interested in CNC a dividing head is irrelevant, but you could CNC it as another axis I guess
10:00 GuShH_ MrCurious: hm?
10:00 GuShH_ Who wrote that description? it's worse than broken Chinglish.
10:01 WaldoPepper Its easier to recommend something if one knows...
10:01 GuShH_ WaldoPepper: irrelevant since different machines exist in different parts of the world
10:01 MrCurious yeah
10:01 GuShH_ I wouldn't try to CNC such a beast
10:01 GuShH_ the cost would be too high.
10:02 WaldoPepper Ok, so you are looking for a manual machine.........
10:02 GuShH_ but that's got power feeds in all directions and a nice universal head.
10:02 GuShH_ I'm not buying a bridgeport, don't suggest it.
10:02 GuShH_ unless that is, you are willing to pay for it?
10:02 GuShH_ most bridgeports were pure hype... I mean, they even moved to plastic handles after a point, what the hell.
10:03 GuShH_ WaldoPepper: I don't mind rust or a few things to fix, specially if it's just electrical.
10:04 GuShH_ looking to rescue something instead of buying china shit for a change.
10:04 GuShH_ none of these machines have DROs in them... that's another price point
10:07 GuShH_ cnc conversion from ball screws to drivers, steppers and all the rest, ends up costing more than the machine is worth...
10:07 GuShH_ and all the while you have no machine to work with until it's done.
10:15 SquirrelCZECH CNC? I am interested :)
10:16 SquirrelCZECH wow
10:16 SquirrelCZECH WaldoPepper: that RoR thingy looks nice
10:16 SquirrelCZECH python, hmm :)
10:19 WaldoPepper RoR? Or ROS? ;-)
10:20 WaldoPepper Can you provide a link?
10:22 SquirrelCZECH *ROS
10:22 SquirrelCZECH sorry
10:22 SquirrelCZECH :)
10:23 WaldoPepper Yes, it is supporting python, which is verny nice....
10:23 WaldoPepper s/verny/very
10:29 GuShH_ pythong
11:06 MrCurious python is such a toy language
11:06 MrCurious it needs to use { } for blocking, then i could loe it
11:06 MrCurious white space based blocking is sooooooo fortran/cobol era
11:30 fisix python is excellent
11:30 GuShH_ pythong!
11:30 ShH_ feeds fisix some py
11:30 fisix :)
11:31 GuShH_ here, use your pyFork
13:20 GuShH_ rue_more: eek look at the table on this poor little thing http://mla-s2-p.mlstatic.com/fresadora-de-banco-craf-cono-2-con-mesa-cruz-14642-MLA20088398343_042014-F.jpg how on earth can someone manage that?
13:21 GuShH_ it looks like the surface of the moon
13:21 GuShH_ these dirty shits shouldn't be allowed to own tools.
13:21 Hyratel1 what the hell
13:22 Hyratel1 it looks like the slots were repeatedly overtorqued
13:23 GuShH_ looks like a lot of mill and drill bits touching it and eventually causing that surface
13:23 GuShH_ you think it's all sheared iron?
13:24 GuShH_ there's some on the corners, at any rate that machine was butchered, sad since they used to be nifty bench mills
13:24 GuShH_ they're always dry or rusty and with missing parts and they always have something butchered
13:27 Hyratel1 that working table you could remanufacture if you want it for pure usability, and not "omg, 100% complete!"
13:28 GuShH_ I'm mostly looking at bigger machines, but that keeps popping up, they're all in bad condition though
13:28 GuShH_ you have to wonder about the leadscrews..
13:30 Hyratel1 ergh, yeah that's a point
13:30 Hyratel1 well, if you want a fixerupper that looks like a good candidate
13:30 GuShH_ the gibs you can adjust, although there would still be wear (ie. tight spots where there isn't any wear)
13:30 GuShH_ I'd like something a bit more complete.
13:31 Hyratel1 what' the vintage on that anyway
13:31 GuShH_ 50-60s I bet
13:31 GuShH_ no info online
13:31 GuShH_ just like these http://mla-s2-p.mlstatic.com/agujereadora-fresadora-marca-netur-9383-MLA20014758542_122013-F.jpg but I don't like round columns.
13:32 GuShH_ and that has a tiny table.
13:34 GuShH_ what are these places.... http://mla-s1-p.mlstatic.com/fresadora-universal-nro1-4083-MLA139335654_4241-F.jpg jesus.
13:35 GuShH_ And, I can't help but wonder, such a massive body and knee with such a wimpy vertical head?
13:40 GuShH_ at least it's got the cardanic transmission all in there
14:49 MrCurious i got zeee tank
18:57 f00bar80 if a servo is too hot, it means i
18:58 f00bar80 it means i'm using a power source with very much of current ?
18:59 GargantuaSauce it's exerting more force than it should be
19:02 rue_more f00bar80, your working it too hard
19:02 rue_more use a larger servo or counterbalance your arm
19:04 rue_more GuShH_, its about vibration
19:05 rue_more i bet they have the horizontal parts for that one eh?
19:07 e_more twitches at the sight of the key left in the dividing head like
19:22 f00bar80 rue_more, what makes you say that and not it's much of current ?
19:25 rue_more a device will only pull as much current as its requires for the load
19:26 rue_more if there is too much current its not because of the supply
19:26 rue_more you could have a 50000A power supply and the motor would draw the same current is does now
19:29 rue_more the only difference is that if you shorted that supply the wire would probably catch fire faster
19:33 rue_more armyofevilrobots, is it the second thursday of the month?
19:54 f00bar80 rue_more, i have the servo on the joint of 2 mecanno beams as in here https://www.dropbox.com/s/xaieptg6fzawt58/2014-04-04%2021.06.07.mp4 tried to keep it fixed with wire , nilon wire all kind of things and still it's not fixed , and i think also that's why it becomes too hot, so do you have an suggestion on how to fix it ?
20:16 f00bar80 ??
21:24 rue_more yup
21:25 rue_more you need to grab the servo horn, not just the screw in the middle
21:25 rue_more f00bar80, still around?
21:47 armyofevilrobots rue_more; third.
21:47 armyofevilrobots But I'll be missing next week; in Atlanta again.
21:47 armyofevilrobots https://www.openstack.org/summit/openstack-summit-atlanta-2014/
21:47 armyofevilrobots which is actually a lot cooler than going to meetings all week.
22:48 MrCurious man i wanted to go to that
22:52 MrCurious hopefully there will be lots of presentations captured from it
23:11 rue_more k
23:11 rue_more well I got some casting sand mixed up!
23:11 rue_more I think its pretty good, cant wait to try it
23:12 orlock awesome
23:12 orlock what you casting?
23:17 rue_more anything, everything
23:17 rue_more I need pullies to bend 1.25" pipe for the control cage of a 12' mecha
23:17 rue_more (aluminum)
23:45 rue_more Tom_itx, today I realized that if I wanted 'proper' dyndns for the house, I could use one of the free accounts that comes with a network cable digital video recorder
