[03:14:48] <Jak_o_Shadows> Hmm. Why bother trying to electrically trim a pot, when you can just fake it in software instead
[03:33:20] <cobreadmonster> Hello.
[03:33:34] <cobreadmonster> How do I get started with robotics?
[03:43:45] <robopal> do you have any experience in programming? do you like making stuff from scratch or you prefer to assemble pre-made modules? what is your budget? do you have something specific you want to make? would you like to work with low level electronics or not?
[03:44:16] <robopal> you need to answer these kind of questions for yourself first
[04:45:36] <U-Scripter> should I buy a 55K resistance of 101K resistance MPU 6050??
[04:46:40] <deshipu> resistance is futile
[04:46:50] <theBear> me scriptah eh
[04:48:40] <veverak> hmm
[04:48:51] * veverak is curious
[04:48:57] <veverak> how many of you know what is ansible?
[04:49:07] <theBear> heh <insert bad sexuality related joke here>
[04:49:17] <theBear> anything i can ans
[04:49:21] * veverak wants to use it in robotic project as way to setup ARM for robot
[04:49:37] <veverak> was curious if it will be new thing for most people or not :)
[04:49:47] <theBear> i don't think it's a word
[04:49:50] <deshipu> veverak: you refer to the Ender's books or the confuguration management software?
[04:50:21] <deshipu> veverak: ansible is a faster-than-light communication device
[04:50:30] <veverak> deshipu: I red enders books
[04:50:39] <veverak> but that was long time ago it seems, because I forgot it :D
[04:50:49] <veverak> deshipu: "configuration management software"
[04:51:02] <veverak> https://en.wikipedia.org/wiki/Ansible_(software)
[04:51:50] <veverak> this is actuall breakdown for what it will do
[04:51:52] <veverak> https://bpaste.net/show/17242e9d3d7a
[04:51:52] <deshipu> Ursula K. Le Guin coined the word ansible in her 1966 novel Rocannon's World.
[04:51:54] <deshipu> interestin
[04:52:35] <veverak> idea is that newbie will git clone repo with ansible stuff and just run ansible repo/main.yaml
[04:52:38] <veverak> tadaaaaah
[04:52:40] <veverak> robot setuuped
[04:52:42] <veverak> :)
[04:53:35] <veverak> and for other people, given that ansible yaml format is well readable
[04:53:45] <veverak> they can go through it and explore what it does/setups
[04:54:40] <deshipu> I have to admit that I much prefer programing in Python than in YAML
[04:55:31] <veverak> wut? :)
[04:55:43] <veverak> yaml -> configuration file format?
[04:55:50] <veverak> or, just data storage more or less
[04:56:20] <deshipu> I work on a project at work that uses extensively ansible and yaml files, and they have all sorts of special yaml commands that basically let you program in it
[04:57:21] <deshipu> veverak: https://github.com/openstack/tripleo-heat-templates/blob/master/net-config-linux-bridge.yaml#L68 <-- like the "get_param" key here
[04:57:30] <deshipu> it's horrible
[04:58:56] <veverak> yeah
[04:59:00] <veverak> that's horrible :D
[04:59:05] <veverak> deshipu: I won't rape ansible
[04:59:48] <veverak> more like standart ansible playbooks
[04:59:50] <veverak> https://github.com/ansible/ansible-examples/blob/master/lamp_simple/roles/common/tasks/main.yml
[05:00:30] <deshipu> it's still a bash script disguised as a configuration file
[05:02:37] <veverak> yeah
[05:02:55] <veverak> but bash script that can detect operating system and you can run it repeatedly
[05:03:08] <veverak> or if something changes in playbook, just rerun it
[05:03:31] <veverak> and it can template configs or use regex on configs in reasonable manner
[05:03:46] <veverak> just... it allready has all the things I would endup doing on my own in custom bash script
[05:04:10] <veverak> not to mention that if it's ansible, people don't have to rely on me, they can propably repair ansible on their own
[05:04:20] <veverak> you know, it have tons of tutorials and stuff...
[05:05:28] <deshipu> yes, but it's still far from proper configuration management
[05:06:03] <veverak> what's missing? :)
[05:06:58] <deshipu> it's still a script that is getting executed in a certain order
[05:07:15] <deshipu> you don't describe a desired state and let the computer figure out how to get there
[05:07:31] <deshipu> you still write recipes telling it what to do
[05:13:11] <veverak> yeah
[05:13:23] <veverak> good enough for me though...
[05:13:25] <veverak> :0
[11:57:09] <rue_bed> date
[12:14:31] <Tom_itx> 26
[12:35:30] <rue_shop3> i was looking for the time
[12:35:43] <rue_shop3> the clock on the bed machine uses a grey on grey font for the time
[12:35:43] <deshipu> where did you see it last time?
[12:35:55] <rue_shop3> deshipu, before
[14:50:23] <sherrardtr> hello!
[15:21:57] * rue_shop3 scratches his head and tries looking at the plan upside down
[15:22:08] <rue_shop3> my notes on how to assemble this pipe bender are... lacking..
[15:24:56] <theBear> put snake in middle, apply bendy force
[15:25:11] <rue_shop3> its for 2.5" EMT
[15:25:50] <rue_shop3> which is for making a gyro cage
[15:25:57] <rue_shop3> one you strap into
[15:26:27] <rue_shop3> the top roller is supposed to get pushed down when you tighten it up
[15:26:28] <rue_shop3> but
[15:26:45] <rue_shop3> the scribble dosn't really show how thats supposed to work
[15:27:34] <rue_shop3> I think its a skipped detail
[15:28:20] <rue_shop3> oh, maybe
[15:30:34] <rue_shop3> stroke should be....
[15:30:50] <rue_shop3> 10cm
[15:31:03] <rue_shop3> 55mm to 45mm
[15:31:15] <rue_shop3> 10cm is...
[15:31:30] <rue_shop3> 4 inches
[15:31:45] <rue_shop3> that explains the 4" there...
[15:32:39] <rue_shop3> I'm gonna need a peice of BRUTAL threaded rod
[15:36:48] <rue_shop3> I wonder if this 5/8" is big enough
[15:40:06] <rue_shop3> AND I THOUGHT THIS WAS JUST AN ASSEMBLY JOB NOW!
[16:07:35] <rue_shop3> OH HELLO
[16:07:55] <rue_shop3> 45mm -> 55mm is 10mm, which is 1cm
[16:07:57] <rue_shop3> not 10
[16:33:46] <rue_shop3> damn well already 2:00
[19:27:51] <rue_shop3> ok, doI weld the frame now?
[19:28:00] <rue_shop3> I suppose I could tack it
[19:28:04] <rue_shop3> hmmmmm
[19:29:35] <rue_shop3> ... I want to work on the vacuum former now
[19:33:12] <Tom_itx> naw work on the silkscreener
[19:33:45] <SpeedEvil> work on your fitness
[19:51:48] <rue_shop3> you know, I'm gonna need a 12' mecha to build this 12' mecha
[19:52:04] <rue_shop3> what we have here is a classic robot and chicken problem
[19:52:10] <rue_shop3> er chicken and egg
[19:52:38] <rue_shop3> i hate it when a welder spark gets in your ear and sets everything in there on fire
[20:07:12] <SpeedEvil> Burning it out is an effective way to remove earwax
[20:18:32] <rue_shop3> hmm, its assembling
[20:18:39] <rue_shop3> few things to work out yet
[20:18:48] <rue_shop3> 6pm
[20:18:50] <rue_shop3> hmm
[20:52:26] <rue_shop3> the pipe roller is comming togethor
[20:52:50] <rue_shop3> may be a minor catch as its too heavy to lift now that its mostlyassembled
[21:01:10] <SpeedEvil> you need to make a pipe-roller-lifter
[21:01:50] <SpeedEvil> https://d.ibtimes.co.uk/en/full/1447257/power-loader-exoskeleton-aliens.png
[21:02:22] <rue_shop3> the REASON for making the bender is to make a gyro cage for remotly controlling a 12' mecha
[21:02:28] <rue_shop3> irony?
[21:02:37] <rue_shop3> or just catch22?
[21:02:37] <SpeedEvil> hah
[21:03:14] <rue_shop3> on paper it all seems so.... weighless...
[21:03:27] <SpeedEvil> yeah
[21:03:36] <SpeedEvil> do you mean a gimbal cage?
[21:07:13] <rue_shop3> yup
[21:07:35] <rue_shop3> the rings will be 8', 10' and 12' in diameter
[21:10:27] <SpeedEvil> why so much spacing?
[21:10:55] <SpeedEvil> From a ceiling POV
[21:16:12] <rue_house> I think there is onyl about 3" between the rings
[21:18:36] <rue_house> hmm, everyone who dosn't want to be kicked tonight say anything in the next 5 hours
[21:18:48] <orlock> YO GABBA GABBA!
[21:19:07] <rue_house> :)
[21:20:21] <rue_house> seeing the roll bender partly assembled is really motivating
[21:20:30] <rue_house> its been in the works for about 4 years
[21:20:50] <SpeedEvil> rue_house: many will be asleep
[21:21:17] <SpeedEvil> Of course, there is no reason you can't just make a square gimbal
[21:39:47] <Tom_itx> rue_house, you still on your kick kick?
[21:40:01] <rue_shop3> yea there is, my design slides counterweights along it to prebias the balance
[21:40:14] <rue_shop3> Tom_itx, ?
[21:40:27] <Tom_itx> <rue_house> hmm, everyone who dosn't want to be kicked tonight say anything in the next 5 hours
[21:40:47] <rue_shop3> well, looka, we got 75 people with 5? 6? active?
[21:41:04] <rue_shop3> I'd never kick the regulars, sure gather the lurkers
[21:41:04] <Tom_itx> i'm actively not here
[21:41:35] <rue_shop3> but like, who is autofly?
[21:41:37] <Tom_itx> better make up your mind about that board
[21:41:44] <Tom_itx> may not have it long
[21:41:44] <rue_shop3> has autofly EVER said anything?
[21:42:19] <rue_shop3> Tom_itx, well tell me more about it, in context I ahve 3 stm32 comming from china for $2 ea
[21:42:41] <rue_shop3> biab, have to go buy milk
[21:43:02] <Tom_itx> http://www.ebay.com/itm/like/162011402308?lpid=82&chn=ps&ul_noapp=true
[21:44:21] <Tom_itx> http://www.st.com/content/ccc/resource/technical/document/user_manual/70/fe/4a/3f/e7/e1/4f/7d/DM00039084.pdf/files/DM00039084.pdf/jcr:content/translations/en.DM00039084.pdf
[21:45:08] <Tom_itx> huh, didn't realize it has 3 axis accel
[21:46:38] <Tom_itx> that doc pretty well tells it all
[22:12:36] <rue_shop3> thats a nice big one
[22:16:46] <rue_shop3> I wonder what shipping would be
[22:16:53] <rue_shop3> do you want anything for it?
[22:17:11] <rue_shop3> and I want to find that hammer baord I got...
[22:20:56] <rue_shop3> I wonder if I gave it away
