00:25 GargantuaSauce and if you call it HHO you've probably fallen prey to some seriously unscientific views
00:38 omegalpha Triffid_Hunter: you know what im talking about right? thsoe HHO generators that are all over youtube? those guys have it stored in the cases.. so far no reported explosions...but who knows. maybe they blew hemselves up and didnt make a video about it while they were on fire? lol
00:38 omegalpha GargantuaSauce: well i just call it what its called on youtube.. i also called it Brown's gas as well.
00:38 GargantuaSauce it is extremely dangerous to store it in a mixture like that
00:39 GargantuaSauce and if you think it's going to increase your mileage, you're wrong
00:39 Triffid_Hunter omegalpha: apart from the danger of detonation, it's an awful way to store energy, takes something like 5-15x as much energy to produce as you could ever hope to get out of it

06:42 deshipu guys, you probably know this already, but openscad is great :)
06:42 Jak_o_Shadows I find it a little weird.
06:43 deshipu at last I feel in control
06:43 deshipu no strange stuff happening because I moved my mouse wrong
06:58 Tom_itx i hate openscad
06:58 Tom_itx try a real cad program and you may change your mind
06:58 Jak_o_Shadows That's sorta my opinion
06:59 Jak_o_Shadows It beats blender and sketchup though
06:59 Tom_itx and
06:59 Tom_itx if you look at the model everything is defined with triangles
06:59 Tom_itx how silly is that...
07:00 Jak_o_Shadows Do slicer's/CAM packages not tessalate?
07:00 Jak_o_Shadows Or do they do a better job
07:00 deshipu Tom_itx: well, any idea for an *ffordable* real cad program that runs on linux?
07:00 deshipu affordable*
07:00 Tom_itx there's one but i forget the name
07:00 Tom_itx i do cad on windows
07:01 Jak_o_Shadows I quite like inventor, but I have heard good things about solidworks.
07:01 Jak_o_Shadows rhino is somewhat popular, but creo can burn.
07:03 Jak_o_Shadows freecad is slowly moving in the right direction I think
07:15 Tom_itx that may have been the one i was thinking of
07:17 Jak_o_Shadows It's moving in the right direction, but basic things seem too difficult
07:22 Tom_itx what's librecad?
07:23 Jak_o_Shadows 2D.
07:23 Tom_itx http://www.linuxlinks.com/article/20090607033315929/CAD.html
07:23 Jak_o_Shadows Which you know, is good for some things
07:23 Tom_itx about 80% of everything
07:23 Tom_itx http://linuxblog.darkduck.com/2012/10/best-free-linux-cad-software.html
07:24 Jak_o_Shadows I would argue that 3D with assembly is a huge bonus for mech
07:24 Tom_itx yup
07:24 Jak_o_Shadows I did install BRL-CAD once, but it scared me awaay pretty quick
07:27 Tom_itx good to see openscad isn't mentioned in either of those links :)
07:27 Jak_o_Shadows haha
07:27 Jak_o_Shadows I intend on releasing everything as .ipt's and stl's. I am open to other formats though
07:28 Tom_itx good you are open to industry standard formats as well...
07:29 Jak_o_Shadows I have no idea what industry standard formats are
07:29 Tom_itx dxf, iges both come to mine as pretty old ones
07:30 Tom_itx there are newer 3d specific ones as well
07:30 Tom_itx l
07:30 Jak_o_Shadows ah, yeah, If I botheered to do drawings I would release dxf
07:31 Tom_itx i can generally get iges to work on 3d
07:33 Tom_itx ACIS .sat & .sab come to mind too
07:34 Tom_itx .sat is txt, .sab is binary
07:38 Tom_itx solidworks will import just about anything...
07:39 Jak_o_Shadows Solidworks is meant to be good, but i've never used it.
07:39 Jak_o_Shadows Kinda hard to get your hands on.
07:40 Tom_itx i have an old copy but i don't generally use it
07:40 Tom_itx i generally use smartcam
07:40 Tom_itx which is also old now
09:03 rue_mohr2 qcad became freecad that quickly changed to librecad
09:03 rue_mohr2 iirc
09:11 chris_99 nah i'm pretty sure librecad and freecad are different
09:11 chris_99 librecad seems to be 2d only
09:11 rue_mohr2 yea
09:11 rue_mohr2 maybe I just got mixed up
10:27 MrCurious yay! the americans have stopped attacking the a\\mericans!!!
11:10 deshipu http://paste.sheep.art.pl/84be72b7-46b7-4670-92b7-f2592f638fa0/%2Binline <-- this is quite fun!
12:28 deshipu http://letsmakerobots.com/files/userpics/u22498/ukubik-explode.gif <-- final result :)
12:36 mrdata deshipu, wont it fall over then you lift a leg?
12:37 deshipu mrdata: nope, https://www.youtube.com/watch?v=bo90PsbjNTM
12:38 MrCurious do dogs fall over when they lift a leg...
12:38 MrCurious (forgive accidental imagery)
12:39 deshipu mrdata: it would fall if it didn't change its center of gravity
12:39 deshipu mrdata: it shifts the whole body before lifting the leg
12:40 deshipu I could actually make an animation for that too, but I would need to implement inverse kinematics in scad first
12:48 mrdata nice!
12:50 mrdata obligatory share: https://www.youtube.com/watch?v=u3yuxb3-wYo
12:52 deshipu yeah, have you seen the parrot sumo?
12:52 deshipu they've stolen the idea
12:52 deshipu and implemented it in a toy
12:53 mrdata showe me
12:55 deshipu https://www.youtube.com/watch?v=-_8MtJ6WujI
13:00 iveevue Looks good
13:15 MrCurious bow down and be tempted! http://www.ebay.com/itm/291205466462?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
13:17 MrCurious who was doing battery spreadsheet... got one for you to sample and add http://www.ebay.com/itm/High-Capacity-Gold-Battery-Replacement-iPhone-4S-5-5s-3-7V-3-8V-2680mAh-SR-/291102614588?tfrom=291205466462&tpos=unknow&ttype=price&talgo=origal
13:18 robotust1a how's dady?
13:19 robotust1a MrCurious: is daddy happy?
13:47 iveevue Anyone have any programming project ideas?
13:49 MrCurious create an AI
13:49 MrCurious bonus points for self aware, or hyper-serl-aware
13:49 MrCurious hyper-self-aware
13:52 deshipu iveevue: programming as in no-hardware?
13:52 iveevue software only
13:52 robotust1a iveevue: do you have imagination?
13:53 iveevue no :/
13:53 deshipu imagination is overrated
13:53 robotust1a software only is useless
13:53 deshipu make a better cad system :)
13:53 robotust1a NO
13:53 iveevue I don't really have enough stuff to do hardware
13:53 deshipu with a physics engine
13:53 iveevue Have an arduino board lying around...
13:53 deshipu iveevue: that's enough
13:54 iveevue Also have wires and a lot of components
13:54 robotust1a iveevue: do you have girl?
13:54 iveevue wat?
13:54 robotust1a or you are a girl?
13:54 robotust1a girlfriend
13:54 iveevue No, why does that matter?
13:54 deshipu make one \o/
13:54 iveevue ha
13:54 robotust1a WRITE ONE
13:55 iveevue ha
13:55 robotust1a chat bot
13:55 iveevue I have a half-finished irc bot lying around
13:56 robotust1a so, and you are asking for other SW projects?
13:56 iveevue right
13:56 robotust1a finish one first
13:57 iveevue deshipu, How is an arduino board by itself enough?
14:43 deshipu iveevue: it has a build-in led that you can blink
14:43 iveevue lol
14:43 deshipu iveevue: and you can make a switch out of wires
14:43 deshipu so you have input and output
14:44 deshipu also, it has serial console, so you can print stuff
14:44 deshipu so, you could make a morse code decoder, for example
16:35 MrCurious https://www.youtube.com/watch?v=wkk4zv96Dvo
16:35 MrCurious major inspiration
16:47 robotustra channel is dead
16:47 robotustra only rue writes here
16:47 robotustra ppl are not building robots when there is a sun, bitches and ocean
16:47 robotustra only in winter when it's cold and depression
16:53 MrCurious change th words to "people are still making bots"
16:53 MrCurious https://www.youtube.com/watch?v=0ImRyPymRAM
17:10 robotustra cnc porn is better
17:11 robotustra home made amateur cncn porn
17:13 GargantuaSauce ya its the only thing that gets me off
17:13 robotustra yep
17:13 robotustra GargantuaSauce: how are your robots?
17:14 GargantuaSauce no progress
17:14 GargantuaSauce taking two weeks off work now though
17:14 GargantuaSauce so that is gonna change
17:15 GargantuaSauce not 100% sure what i'm going to work on yet, i have a lot of ideas near the top of my todo list
17:19 robotustra me to
17:19 robotustra my one week off starts tobay
17:20 robotustra I'm two days as writing sliccer
17:21 robotustra splited part on counturs
17:21 robotustra now have to generate path
17:21 GargantuaSauce haha why are you writing your own
17:22 robotustra I think it will be faster
17:22 robotustra 2) I write it in C
17:22 GargantuaSauce faster than a perl implementation? no waaaay :V
17:22 GargantuaSauce cool
17:22 GargantuaSauce i kind of plan on writing some cam stuff also
17:23 robotustra 3) I have some ideas about path generation to print at 90 degree
17:23 GargantuaSauce but that will be for 5 axis machining
17:23 robotustra If i sucseed
17:23 robotustra 90 degree without support
17:23 robotustra that's tha plan
17:24 robotustra not for bridges
17:24 GargantuaSauce using your delta?
17:24 robotustra any printer actually
17:24 GargantuaSauce i see
17:24 GargantuaSauce well good luck with that. sounds very difficult
17:24 GargantuaSauce will need careful temperature control
17:25 robotustra no
17:25 robotustra the idea is different
17:25 robotustra I split on layers 8 meg ascii slt in 9 seconds
17:26 robotustra on working pc
17:26 GargantuaSauce yeah slic3r is slow as balls
17:26 robotustra and 4 secs on my i7 zenbook
17:27 robotustra 80000 points
17:28 robotustra what about cura?
17:28 GargantuaSauce well it will certainly get slower as you start having to worry about interactions between layers. support etc.
17:28 GargantuaSauce i havent used that
17:28 robotustra kissslice?
17:29 GargantuaSauce closedsauce
17:29 robotustra kiss is quite fast but I didn't try generated code yet
17:37 robotustra why closed?
17:40 GargantuaSauce i dunno, cause they don't want to give back to the community that spawned their technology and market?
19:15 MrCurious Clarity is the moment in life where you realize that all that has come before was the preparation for all that is to follow...
19:15 MrCurious i am not sure, but i THINK that is a reference to beer

22:58 rue_mohr2 hey
22:59 Jak_o_Shadows hi
23:00 rue_mohr2 I have a better way
23:00 rue_mohr2 my interpolator can operate several robots at the same time
23:00 rue_mohr2 it can do 32000 axies
23:00 rue_mohr2 you can prolly file a few robots under that at once
23:00 rue_mohr2 simotanious synchronized moves
23:01 rue_mohr2 haha I like table 1.1, "robots with 6 dof" and they list like 8 with only 4
23:14 rue_mohr2 hmm I should work out a spherical intersection fucntion for my IK library
