00:00 Hyratel 20/1250 before correction
00:01 e_house tries to work out how to apply the formula to an air mu
00:01 rue_house if A was speed and B was delta speed
00:01 rue_house I think that for an air muscle,
00:02 rue_house A is tension and B is position
00:02 Hyratel asdf gah
00:02 rue_house the position is controled by the difference in pressure
00:02 Hyratel rue_house, have you ever used Sketchup?
00:02 rue_house I have not used windows since 1995, so, no.
00:03 rue_house and I'v never looked back
00:03 rue_house I never have to phone microsoft before online registration never has worked.
00:03 Hyratel ok ok i get it
00:03 rue_house er becuase
00:03 rue_house or had to enter 62 digit codes to get my OS to work right
00:03 Hyratel you don't have to lord your linux superiority over the rest of us plebes
00:04 rue_house or worried about a virus
00:04 rue_house or paid for software
00:04 rue_house tho I wish the world would make it easier to share the software I'v made
00:05 rue_house remember in the height of shareware when you could find racks of disks for no more than the disks were worth?
00:06 rue_house zhanx, so I'v solved it
00:06 rue_house now I can do counteracting air muscles
00:06 rue_house BAM just like that
00:07 rue_house zhanx, I'm gonna make the upper body of the mecha, for doing heavy work
00:07 Hyratel ffff
00:07 rue_house like finishing the brick wall I'm working on
00:08 rue_house casue the landscaping bricks are a little too heavy for m
00:08 rue_house e
00:08 rue_house zhanx, you could use pneumatics for your power suit
00:08 Hyratel the nice thing about Sketchup is you can tap Spacebar to halt whatever current editor tool is active
00:09 rue_house dunno, they never made sketchup for linux
00:09 rue_house bastards
00:09 Hyratel it's simple as far as 3D modellers go but that simplicity enables fast learning
00:10 rue_house I just solved the mixing formula
00:10 rue_house this is AWESOME
00:10 rue_house wolfram alpha sure is an awesome copout for manually solving equations
00:12 rue_house maybe tommorow I'll make the test jig
00:12 rue_house rewrite the controller code
00:13 rue_house if I have counteracting air muscles working, its just a matter of time before I'v taken over the world
00:13 rue_house zhanx, I got the second AC compressor for the mecha
00:14 Hyratel wtf, there's no "halt current"?
00:14 Hyratel except for Esc
00:14 rue_house try right mouse button
00:14 rue_house twice
00:15 Hyratel that [wire]changes corner mode [move]rotates held object
00:15 e_house tries to remm
00:15 Hyratel and it doesn't abort place new
00:15 rue_house sorry I only use eagle to draw official schematics, and I'v not done that in quite a while
00:15 Hyratel the UI feels needlessly difficult
00:16 rue_house Hyratel, for only 99.95 I'll make you a keyboard that is solely comprised of an escape key
00:16 rue_house *shipping and handling extra
00:16 Hyratel :I
00:17 Triffid_Hunter Hyratel: you can bind F2-F12 to basically anything you like if typing stuff in is too slow
00:17 rue_house *product may look like a regular keybaord with everything but the escape key pried out
00:17 Triffid_Hunter Hyratel: menu -> options -> assign
00:17 Hyratel I found that out
00:18 Hyratel I'll get over it after a while, but the UI is just so counter to everything else I'm familiar with it's throwing me off
00:18 rue_house *available in your choice of AT or PS2 connector
00:18 Hyratel are you quite done, rue_house ?
00:19 rue_house never
00:19 rue_house I'm always 5 seconds late for another good comeback
00:20 Hyratel there's no way to grab several things in a schematic either, is there?
00:20 Triffid_Hunter Hyratel: I find it pretty quick now that I'm experienced with it
00:20 Triffid_Hunter Hyratel: yeah, group command
00:20 Triffid_Hunter Hyratel: then you apply other commands with right click
00:20 Triffid_Hunter probably best to bind it to f6 or something like that
00:27 Hyratel :I
00:28 Hyratel the fact that 'move group' behaves like it was an afterthought irritates me to an excessive degree
00:33 Triffid_Hunter Hyratel: yeah it is a bit silly
00:33 Hyratel powerful, but the UI is ... very 80s
00:34 rue_house Hyratel, I'm wokring on a cad program, help me write something better
00:39 Hyratel go on?
09:15 rue_house Hyratel, well, so far I'v failed to start a ui, and I'v failed to figure out how the dxf library works
09:16 rue_house but I did stay at a holiday inn!
09:16 rue_house ;)
09:22 rue_house oo I got the tractor mixing wrong before
09:23 rue_house but I was close
10:11 robotustra ping
14:40 deshipu finally my pcbs arrived
14:42 deshipu soon i will rule the world
15:29 Tom_itx deshipu how many boo boos are on them?
16:06 deshipu Tom_itx: they work
16:12 veverak gonna attack the world with spider robots?
16:13 veverak well... it's not zombie apocalypse but seems nice too
16:34 deshipu assembled one to test it https://cdn.hackaday.io/images/5382781426798346248.jpg
16:34 deshipu that's the cheapest I can get
16:34 deshipu $25 a piece
16:37 veverak awesome!
16:39 deshipu I'm now thinking about that arduino clone they are going to give to 7 year olds in UK
16:39 deshipu if it has enough pins exposed, I could make a design specially for that
16:40 deshipu which would give it a chance of being a project in many schools
16:41 veverak seems awesome :)
16:41 veverak U suppose children would like it!
16:41 veverak :D
16:41 deshipu if we get enough people to play with those things
16:42 deshipu we can come up with some smart tricks to make walking robots easier to make
16:42 deshipu and generally better
16:42 deshipu and nobody has more free time for experimenting than an elementary school kid
16:43 veverak hmm
16:43 veverak that makes my project horrible
16:43 veverak the more I do it, the more complex it gets
16:43 veverak (it's in its nature I suppose)
16:43 deshipu that's normal
16:43 deshipu because *you* learn more and are capable of doing more
16:44 wolfmanjm deshipu: do you have updated gait code for the quadruped?
16:44 deshipu and also, the old stuff is no longer challenging
16:48 deshipu wolfmanjm: yeah, https://bitbucket.org/thesheep/tote/src/3ee9a658fbc2bca700be968d687ebaaff1e203fb/start/creep.ino?at=default
16:48 deshipu not terribly complex
16:48 deshipu I need to add trotting
16:48 deshipu and using that distance sensor for something
16:48 deshipu (obstacle avoidance or following)
19:31 Hyratel ugh
20:07 Hyratel is eagle this stressful to all new users?
20:17 Triffid_Hunter Hyratel: yeah it takes a bit of getting used to
20:17 Hyratel I kinda grok the interface
20:18 Hyratel but that doesn't mean I'm good at it
20:18 Hyratel the UI premise that's found in MS Word/Draw Mode. why can't more EDA programs use that
20:19 Hyratel I got a headache trying to follow a "make a part" tutorial
20:20 Triffid_Hunter Hyratel: I make parts fairly regularly
20:20 Hyratel I'm taking a break. it just got to be too much for me
20:20 Hyratel I did figure out the footprint editor tho
20:20 Triffid_Hunter basically schematic symbol then board footprint then join them together and supply pinouts
