Back
[01:06:39] <rue_house> not I
[01:08:43] <Casper> probably alot for the torque it give
[01:09:19] <SpeedEvil> 10-20 minutes or so on the batteries is not atypical
[01:10:56] <Casper> years ago, father bought some job mate 18V drill for a single day job... job mate is the crappiest brand I ever seen!
[01:12:40] <Casper> the day before the job, he decide to install the 2 missing screws for the front door, #8 4"... put the drill in second speed... nope, 1" left... put drill in first... nope, 1/4" left... try second screw... nope, same, 1/4 left...
[01:13:23] <Casper> took the 14.4V dewalt, mostly discharged, with ooold pack... third speed, no problem doing the screws :D
[01:17:47] <Jak_o_Shadows> I just lug an old mains makita around
[01:18:07] <Jak_o_Shadows> Had it open the other day, the trigger got stuck in.
[01:18:12] <Casper> the job mate made the same sound as those old 6V drills
[01:18:40] <Jak_o_Shadows> Nicest insides on a power tool I've seen. Machine thread screws for the shell, bearings, and a nice simple gearbox.
[01:19:26] <Jak_o_Shadows> Bugger if I know how it does speed control.
[01:22:26] <SpeedEvil> It's likely hidden in the trigger
[01:22:37] <Jak_o_Shadows> Yeah, it is
[01:22:39] <Jak_o_Shadows> But how?
[01:22:45] <SpeedEvil> triac + ...
[01:23:34] <Jak_o_Shadows> oh, yeah
[01:24:16] <SpeedEvil> http://www.electronics-tutorials.ws/power/power24.gif?81223b - very simple
[01:25:27] <Jak_o_Shadows> Yep yep. Thanks
[01:39:52] <rue_house> bah, that dosn't even have spped fedback
[01:42:00] <Jak_o_Shadows> It's a drill, there's a uman in the loop
[01:47:11] <rue_house> the phase margin of a human is terrible
[01:48:36] <mrdata> phase margin?
[01:49:38] * mrdata side steps the issue
[02:27:55] <SpeedEvil> Sometimes lack of speed feedback is good
[03:30:36] <Mr_evil> Hello
[03:32:58] <spacer> Hey
[03:33:39] <Jak_o_Shadows> yo
[03:36:00] <spacer> Found this channel today. Nice
[03:37:37] <deshipu> welcome
[03:37:59] <deshipu> are you building something?
[03:38:15] <spacer> Yep
[03:38:36] <spacer> A tree climbing bot
[03:42:05] <spacer> So not many people here chat huh?
[03:42:22] <vicarion> is it a snake?
[03:45:21] <deshipu> well, as with all channels, there are busy moments and there are times of quiet
[03:45:48] <deshipu> right now the US is already sleeping and the EU is just arriving at work and having coffee
[03:46:37] <SpeedEvil> I'm awake!
[03:47:15] <spacer> Was thinking of a snake but had a look at RiSE and thought of microspines
[03:49:13] <spacer> Has anyone built a snake yet?
[03:49:21] <deshipu> is there a particular use for it once it climbs, or is that just to see if you can do it?
[03:49:35] <vicarion> a robotic snake? i'm sure i've seen them
[03:50:08] <spacer> One that can climb
[03:50:25] <vicarion> snakes are cool. whereas nobody respects a hexapod
[03:51:11] <deshipu> haxapods are not all equal
[03:52:05] <spacer> True that
[03:52:15] <deshipu> spacer:
https://www.youtube.com/watch?v=8VLjDjXzTiU
[03:52:46] <spacer> Check out the RiSE bot. My PI says its not feasible
[03:52:49] <Jak_o_Shadows> I have a friend who made a robotic seasnake
[03:53:41] <vicarion> they make it look so easy
[03:54:14] <deshipu> spacer: have you seen Vertigo?
[03:54:39] <deshipu> spacer:
https://www.youtube.com/watch?v=KRYT2kYbgo4
[03:59:06] <spacer> Do you know how it does that. That's cool
[04:00:10] <veverak> that climbing snake is awesome!
[04:00:12] <veverak> :)
[04:01:16] <deshipu> spacer: the fans push it into the wall, giving it traction
[04:02:07] <spacer> Then it probably can't carry heavy payloads
[04:02:14] <deshipu> spacer: nope
[04:03:26] <deshipu> I don't think any of those climbing robots can
[04:03:26] <spacer> Anyone here fiddled with haptic gloves
[04:03:41] <spacer> Like that Ernest Cline novel
[04:04:03] <vicarion> i am wondering whether it's much more efficient than a quadcopter of similar size, that just hovers by the wall
[04:04:13] <veverak> should be
[04:04:25] <veverak> at least the phase when he drives on the ground is much more effecient
[04:04:31] <deshipu> lol
[04:04:49] <spacer> I think the microspines should carry my requirement
[04:05:12] <deshipu> spacer: what is your requirement?
[04:05:48] <spacer> It should carry atleast 5 kgs
[04:06:10] <vicarion> the size of a baby huh?
[04:06:14] <deshipu> why not a flying robot?
[04:06:28] <deshipu> they are easier to build
[04:06:32] <deshipu> and control
[04:07:39] <spacer> Yeah but I need a climber
[04:09:18] <deshipu> any particular kind of surface it needs to climb?
[04:09:30] <deshipu> trees of a particular diameter?
[04:09:40] <deshipu> with branches?
[04:09:51] <spacer> Branches yes
[04:10:04] <deshipu> branches make it hard
[04:10:19] <spacer> An alien bot won't have the maneuverability
[04:10:20] <vicarion> do windows and steel. then your bot can rescue people from burning skyscrapers
[04:10:38] <deshipu> alien?
[04:10:40] <spacer> *ariel
[04:11:32] <deshipu> aerial bots tend to be much more maneuverable actually...
[04:11:48] <spacer> Who do you think I am vicarion. Boston dynamics
[04:12:15] <deshipu> spacer: what's the actual task of that robot? what do you need it to do?
[04:12:38] <spacer> Cut fruit
[04:13:25] <deshipu> ah, so not only climb on the trunk, but also move along the branches
[04:13:44] <deshipu> and thin branches, at that
[04:14:43] <deshipu> https://www.youtube.com/watch?v=mPjylrtNCz4
[04:16:45] <spacer> Gotta love nature with its millions of years of research time
[04:17:13] <vicarion> *billions
[04:17:46] <vicarion> hmm, maybe we could just train coconut crabs to pick fruit instead
[04:17:54] <deshipu> note that it doesn't have adhesive feet
[04:18:09] <deshipu> just strong enough to grab that tree
[04:18:17] <vicarion> use them to replace low income agricultural workers
[04:19:22] <deshipu> vicarion: most large orchards actually have rows of 1m tall trees, and the fruits are picked with harvesters
[04:19:45] <deshipu> vicarion: at least that's how it is for apples, oranges or lemons
[04:22:55] <vicarion> very convenient. maybe they could just engineer the trees to grow their fruit into fruit packing boxes
[04:23:27] <spacer> Well the pi got a grant to do the climbing bot and he roped me into it since I'm a mechanical engineer
[04:24:13] <deshipu> tough luck :)
[04:24:31] <deshipu> I'd love to have a furniture climbing robot at my house
[04:24:39] <deshipu> I did make some attempts, but all failed
[04:24:43] <Jak_o_Shadows> Where are you from spacer?
[04:26:07] <spacer> Goa India
[04:26:30] <spacer> What about you all
[04:26:38] <Jak_o_Shadows> South Australia
[04:29:18] <deshipu> Alps
[04:31:08] <spacer> Have you seen nao?
[04:31:20] <spacer> The humanoid bot
[04:31:34] <spacer> Man I'd love to afford it
[04:32:21] <vicarion> how well can it walk?
[04:36:19] <vicarion> hmm, looks very agile in its videos
[04:36:31] <spacer_> Cool isn't it
[04:36:39] <deshipu> it does the ZMP thing
[04:36:46] <deshipu> with the feet sensors
[04:38:01] <spacer> It's about 6-7 k usd
[04:38:32] <deshipu> well, be prepared for your climbing robot to cost too
[04:39:22] <deshipu> the actuators are not cheap
[04:39:25] <deshipu> and the sensors
[04:39:28] <vicarion> i understood agile bipedalism was an unsolved problem
[04:39:36] <deshipu> vicarion: is
[04:39:39] <veverak> nice
[04:39:44] <veverak> nao walks pretty good I see
[04:39:57] <deshipu> it doesn't walk like humans do
[04:40:07] <deshipu> it uses 20 times more energy
[04:41:00] <deshipu> try walking around with you knees bent like that
[04:41:06] <veverak> yeah
[04:41:45] <spacer> Anyone try any vr?
[04:41:56] <joga> yeah
[04:42:11] <vicarion> i'm trying to find a plan of its points of articulation...does it have the equivalent of a spine?
[04:42:12] <spacer> Is it the future?
[04:42:30] <spacer> Nao?
[04:43:03] <joga> spacer, it will definitely become a thing, whether we get the utopia indistinguishable from reality I don't know, but now it at least works technically, unlike in the 90s
[04:43:04] <vicarion> yeah, the nao
[04:43:32] <joga> I borrowed a dk2 for a few weeks, had to return it yesterday though :(
[04:43:43] <joga> tried out some stuff and was quite impressed
[04:43:54] <vicarion> every bipedal animal i can think of has a spinal column. i presume it helps them balance a lot
[04:46:09] <deshipu> vicarion: balancing is not the problem so much
[04:46:24] <deshipu> vicarion: re-using the energy of the step is
[04:47:01] <deshipu> compare how Nao walks with this:
https://www.youtube.com/watch?v=-Vg-BdXps50
[04:47:32] <deshipu> no spinal column
[04:48:13] <spacer> Gtg guys bbl
[04:48:16] <spacer> Tc
[04:50:29] <vicarion> later
[04:51:09] <vicarion> deshipu: so how do bipedal animals reuse the energy?
[04:51:50] <deshipu> vicarion: by using the inverted pendulum
[04:52:14] <deshipu> vicarion: the leg is mostly straight once it hits the floor, and the body swings over it to the other side
[04:52:36] <deshipu> (there may be some flexible component there, a "spring" in the gait)
[04:53:18] <deshipu> unfortunately that makes your center of mass go up and down constantly and complicates the calculations immensely
[04:54:37] <vicarion> they're storing some of this energy in the motion of their upper body?
[04:55:02] <deshipu> yup
[04:55:39] <deshipu> most of it, in fact
[04:57:09] <deshipu> we can build walking bipeds that have no motors at all and just go down a ramp
[04:57:14] <deshipu> using that principle
[04:57:44] <Jak_o_Shadows> Yeah, tendons and muscles are springy
[04:59:01] <vicarion> most of the bipeds i'm looking at on youtube sound like they're using servos or other motors to move, not synthetic muscles
[04:59:36] <deshipu> you don't need synthetic muscles
[05:00:39] <deshipu> https://www.youtube.com/watch?v=qMAGiCpw7Zo <-- this is actually much better than Nao
[05:02:12] <vicarion> that robot is pimp walking
[05:02:51] <Jak_o_Shadows> I don't think servo motors are the answer to bipeds
[05:03:48] <Jak_o_Shadows> Or at least servo motors directly on joints
[05:03:50] <deshipu> what is the question? :P
[05:03:59] <deshipu> Jak_o_Shadows: no, you need springs too
[05:05:43] <Jak_o_Shadows> Yep
[05:06:22] <deshipu> but I don't even think we need biped robots
[05:06:53] <deshipu> humans are bipedal because of particular constraints the natura had at the time
[05:07:16] <deshipu> technology has different constraints and a different solution is optimal in this situation
[05:07:38] <deshipu> unless, of course, your problem is "make it look like a human", which, in my option, is silly
[05:09:22] <vicarion> idk, it helps to try and duplicate something you know works. then at least you know you're working towards a solvable problems
[05:10:29] <veverak> that's cheap reason :)
[05:10:47] <veverak> I suppose there are enough animals in the nature
[05:11:30] <deshipu> vicarion: the thing is, solving the problem with other means is easier than replicating the nature's solution
[05:11:39] <vicarion> that's what i tell myself everytime i have a hamburger. 'nature's got enough animals. they won't miss this one'
[05:12:02] <deshipu> vicarion: take flying as an example -- we only recently learned to actually build working ornitopters
[05:12:12] <vicarion> deshipu: absolutely, powered flight being an obvious example
[05:12:25] <vicarion> but we've said this problem isn't solved yet
[05:12:46] <deshipu> I don't even think it's a problem
[05:12:52] <deshipu> it's one of the possible solutions
[05:13:08] <deshipu> the actual problem is a mobile robot that can operate in human spaces
[05:14:08] <vicarion> which were mostly designed for humans who can walk like humans
[05:14:39] <deshipu> not necessarily
[05:14:45] <deshipu> it doesn't have to be a snowman
[05:17:20] <deshipu> vicarion: the requirement is to have *at least* the mobility and reach of a human
[05:17:31] <deshipu> vicarion: who says we can't do better?
[05:17:41] <deshipu> vicarion: look a the robosimian for instance
[05:19:29] <vicarion> sure
[05:21:04] <deshipu> also, look how well dogs and cats operate in spaces "designed for humans"
[05:22:50] <vicarion> has anyone ever built a robot cat that can walk across a fence?
[05:23:09] <deshipu> there is a biped that can do that
[05:23:19] <deshipu> no idea about a quadruped
[06:37:30] <anonnumberanon> vicarion, yes
[06:38:00] <anonnumberanon> biped, and since that's harder to do than quadruped, by extension, yes
[06:38:34] <anonnumberanon> and since it wasn't a fence but just a wire, etc... etc...
[06:38:36] <anonnumberanon> been done
[06:39:15] <deshipu> actually may be harder for a quadruped in some aspects
[06:39:37] <deshipu> hard to tell without trying
[06:40:44] <anonnumberanon> yeah agree, although I think, not harder, but very different and just as hard
[06:41:18] <deshipu> so many projects, so little time
[06:52:59] <jhylands> yeah, no kidding deshipu
[07:01:20] <deshipu> I need to find a day job where I can do this stuff
[07:03:18] <jhylands> in my day job right now I'm designing a tethered quadcopter
[07:04:20] <veverak> deshipu: same here
[07:04:31] <veverak> but where one finds such a job?
[07:04:54] <jhylands> you win the lottery, and hire yourself I guess
[07:05:09] <jhylands> which means in reality you do it as a hobby
[07:05:10] * veverak always thought about bright idea for pattent
[07:05:12] <deshipu> jhylands: at Mozilla?
[07:05:17] <veverak> only problem is that I don't really like patents
[07:05:29] <jhylands> deshipu, no, I'm on a 3-month sabbatical
[07:05:44] <deshipu> nice
[07:06:15] <jhylands> I'm working with a company in South Africa that does tech for game reserves to combat poaching
[07:06:16] <deshipu> veverak:
http://www.veritystudios.com is looking for someone to build quadcopters for them
[07:06:50] * veverak got no experience with quadra
[07:06:55] <veverak> more or less because there is no time :D
[08:07:34] <maiden> PAL Robotics are searching for more staff, check with them:
http://pal-robotics.com/en/company/
[08:11:20] <maiden> i like this "Job Description
[08:11:20] <maiden> We are always looking for talented people. If you think you're a good fit, apply!"
[08:11:27] <maiden> https://www.smartrecruiters.com/PalRobotics/77824265-spontaneous-applications
[08:12:16] <robopal> pal robotics eh?
[08:14:05] <jhylands> if you don't mind living in Spain
[08:16:02] <deshipu> I can't move
[08:40:59] <maiden> deshipu are you stuck?
[08:41:02] <maiden> :p
[08:41:49] <deshipu> yeah, pretty much stuck in this city
[08:43:45] <maiden> what city is that?
[08:46:17] <maiden> Have moved about every second year my entire life. it was quit fun to live in Shanghai :D
[08:47:19] <deshipu> Zürich now
[08:47:29] <deshipu> well, I just moved here last year
[08:47:47] * veverak is still on uni so doesn't want to move
[08:47:51] <deshipu> but I hope to stay at least 4-5 years
[08:47:57] <veverak> and also got a quite nice hackerspace in a city
[08:48:22] <jhylands> last house I lived in for 12 years
[08:48:28] <jhylands> just moved last summer
[08:48:55] <deshipu> jhylands: did you get used to it already?
[08:49:01] <jhylands> oh yeah
[08:49:18] <jhylands> this new house is much better - I have my own office/workshop in the basement
[08:50:56] <jhylands> its only a 10' x 10' room, but its twice the floor space of my office in the old house
[09:02:12] <maiden> nice :D
[09:03:35] <maiden> started a robotics society in Västerås when i lived there, i really miss that here.
[09:03:49] <maiden> are currently living in a small town in the middle of nowhere
[09:04:13] <veverak> nah
[09:04:29] <veverak> that's only thign I miss from hometown, had bigger room than in city where I study
[09:04:35] <veverak> and bigger table, much more tools ... nah
[09:04:59] <maiden> had to move here because my wife's family lives here, and with two small children we need all the help we can get..
[09:11:31] <maiden> would like to get a bigger house with a connected garage, so i can get a MIG Welder, drillpress etc etc
[09:11:54] <jhylands> My kids are attending college/university now, so time isn't such a big factor for me
[09:12:03] <rue_house> 3d printer and a cnc
[09:13:17] <jhylands> I've got a new 3D printer on order now
[09:13:27] <maiden> same here
[09:13:28] <veverak> why 3d printer with cnc?
[09:13:29] <veverak> :)
[09:13:37] * veverak got one that needs finish
[09:13:42] <rue_house> suitability
[09:13:43] <jhylands> I have both, and 3D printing is so much simpler
[09:13:44] <veverak> or, just more upgrades? dunno
[09:13:52] <maiden> 3d printer on the way, will make a "mostly printed CNC"
[09:13:52] <jhylands> CNC is a lot of work
[09:13:58] <veverak> nah
[09:14:01] <maiden> already got a K40 laser cutter
[09:14:05] * veverak thinks mostly printed cnc will suck propably
[09:14:26] <jhylands> well, if you wanted to cut cardboard, it would probably be okay
[09:14:33] <rue_house> some stuff makes better out of metal
[09:14:36] <veverak> jhylands: exactly my point
[09:14:50] <jhylands> I use my mill to cut aluminum and brass, and delrin plastic
[09:14:53] <deshipu> I have a dremel clone...
[09:15:11] <jhylands> CNC or handheld?
[09:15:13] <rue_house> best not to have a real dremel
[09:15:21] <rue_house> they are made like **** these days
[09:15:32] * veverak got older dremell and is satisfied
[09:15:36] <rue_house> and they dont support the warranty, esp if your in canada
[09:15:39] <veverak> maiden:
http://www.aliexpress.com/item/Free-ship-CNC-3020-DIY-CNC-Frame-with-ball-screw-optical-axis-and-bearings/1958115282.html?spm=2114.01020208.3.27.dusNFj&ws_ab_test=searchweb201556_1,searchweb201644_2_79_78_77_82_80_62,searchweb201560_8
[09:15:46] <veverak> maiden: I would buy this if I would build CNC
[09:15:48] <veverak> :)
[09:16:02] <veverak> but my dremell is older, true
[09:16:12] <rue_house> wow, aren't you spendy
[09:16:17] <jhylands> I have a Sherline CNC mill, and a Sherline manual lathe
[09:16:37] <rue_house> jhylands, is the mill modified?
[09:16:41] <jhylands> not really
[09:16:49] <veverak> rue_house: I don't posses skills yet to make CNC cheaper than that kit
[09:16:51] <veverak> :)
[09:16:55] <veverak> with same capability
[09:16:58] <rue_house> hmm, I know tom has put a lot of changes into his
[09:17:20] <jhylands> I'm not a machinist, and since I started 3D printing a lot, I don't do a lot of milling
[09:17:42] * veverak got 3d printer broken a lot
[09:17:49] <veverak> but I suppose only shitty thing that remains is extruder
[09:17:49] <jhylands> a lot of people have these tools for the sake of having them, but I just use them to build robots
[09:18:05] <veverak> but most of the problems are my mistakes
[09:18:06] <jhylands> veverak, that's why I typically spend more money and buy quality tools
[09:18:13] <deshipu> for the sake of having robots ;)
[09:18:13] <veverak> yeah
[09:18:29] <veverak> jhylands: when I get it I didn't knew why it's shitty
[09:18:32] <jhylands> I just ordered a Raise3D N1 dual extruder
[09:18:33] <veverak> and I learned a lot on it
[09:18:38] <veverak> like A LOT
[09:18:41] <veverak> so it's not waste
[09:19:10] <jhylands> I paid $350 for a crappy M3D printer, and it is a total waste of space
[09:19:22] * veverak got reprap i3
[09:20:10] <rue_house> huh, box printer
[09:20:19] <veverak> a lot of upgrades
[09:20:23] <rue_house> its tiny
[09:20:24] <veverak> prints much better than standart i3
[09:20:30] <veverak> but still needs some things to do :)
[09:20:36] <jhylands> rue_house, what is tiny?
[09:20:43] <rue_house> M3d
[09:20:45] <jhylands> yeah
[09:20:52] <jhylands> I can't get the damn material to stick
[09:20:59] * veverak likes e3ds big box
[09:21:08] <jhylands> I backed a heated bed kickstarter, and hopefully someday that will deliver
[09:21:10] <rue_house> jhylands, did you clean the bed with acetone?
[09:21:20] <jhylands> rue_house, its buildtak
[09:21:26] <jhylands> you can't clean it with acetone
[09:21:38] <veverak> how is buildtak?
[09:21:42] * veverak uses carbon plate
[09:21:42] <rue_house> well put tape on it and print pla
[09:21:52] <veverak> it holds pretty well, but nah, heating it up starts to be pain
[09:22:00] <jhylands> The N1 comes with buildtak, but its a heated bed and enclosed printer
[09:22:09] <jhylands> I don't like PLA
[09:22:35] <jhylands> I do all my printing in ABS
[09:22:45] <rue_house> not with your m3d
[09:22:50] <jhylands> well, not yet
[09:22:53] * veverak uses ABS inside acrylic box on carbon plate
[09:23:03] <jhylands> once I get the heated bed it should be okay for ABS
[09:23:03] <veverak> works quite well after I figured out that I've got bad sensors on heated bed
[09:23:06] <veverak> :)
[09:23:12] <veverak> and yeah, heated bed
[09:23:19] <jhylands> right now I print ABS on a Mojo, but that's expensive
[09:23:27] <rue_house> jhylands, you DONT have a heated bed and your trying to do ABS?
[09:23:46] <veverak> jhylands: I setuped so far 3x reprap i3 (one is mine, two got my boss)
[09:23:52] <veverak> all 3 of them uses heated carbon plate
[09:23:58] <veverak> all 3 of them usually got no problem
[09:24:17] <veverak> only once in a while you have to clean the bed with acetone and "clean it" with ABS part
[09:24:24] <veverak> (it leaves thick ABS layer and it's awesome)
[09:24:31] <rue_house> myprinter cost me about $300 and thats was ith 2kg of plastic
[09:24:42] <veverak> that is when you heat it correctly :)
[09:24:54] <jhylands> I like my tools to just work
[09:24:59] <veverak> only thing that sucks for me is still extruder :/
[09:25:06] <veverak> needs too much care and attention
[09:25:07] <jhylands> so I'm hoping the N1 will be more a plug and play experience
[09:25:21] <rue_house> 3d printers arn't yet
[09:25:27] <rue_house> did you spend $2000 or more?
[09:25:29] <jhylands> well, my Mojo is
[09:25:38] <jhylands> the N1 was $1500 USD
[09:25:58] * veverak doesn't mind taking care of it, if it isn't too much
[09:26:00] <veverak> :)
[09:26:20] <veverak> problem is that I can't find extruder that would be reliable and I didn't found it overpriced
[09:26:26] <jhylands> The Mojo is amazingly plug and play, but it was a $10,000 printer
[09:26:32] * rue_house just realized there is a language barrier between USD and CAD right now
[09:26:34] <veverak> maybe I should finally switch to 1.75mm material
[09:26:47] <jhylands> fortunately, I didn't have to pay for it
[09:27:08] <maiden> veverak: no, for CNC i would go with:
http://store.amberspyglass.co.uk/eshapeoko-cnc-milling-machine-mechanical-kit.html
[09:27:11] <rue_house> this is why I should amke and sell pritners
[09:27:19] <rue_house> people who pay WAY too much for thigns
[09:27:45] <jhylands> it depends - that argument only holds if your time is worth nothing
[09:28:00] <jhylands> I've spend 0 hours working on my Mojo
[09:28:05] <rue_house> dodn't take me long to build a printer that sells for $2000
[09:28:14] <veverak> maiden: sucks, too many opened rails, would need enclosure a lot
[09:28:22] <veverak> :)
[09:28:24] <jhylands> I've probably printed several hundred hours
[09:29:08] <rue_house> hmm I ned to start another plate of objects for my dear ma
[09:30:28] <maiden> veverak: 2030 is to small
[09:30:44] <maiden> 100x150 is sweet :D
[09:30:55] <veverak> yeah
[09:31:02] <veverak> but main point of CNC is removal of material
[09:31:09] <veverak> and that material tends to go everywhere
[09:31:14] <rue_house> the new printer I'm designing is 37x37
[09:31:17] <veverak> so trust me, cnc like shapeoko can be quite a pain
[09:31:19] <veverak> ;)
[09:31:35] <maiden> no, not that bad ;)
[09:31:57] <maiden> have several hundreds of hours logged in front of different CNC machines
[09:32:33] <maiden> i guess it depends on what you use them for
[09:32:42] <maiden> i only work with plastic and metal
[09:32:58] <veverak> true
[09:33:11] <maiden> i mostly do sheetmetal contours
[09:33:21] <maiden> then bend the parts that needs bending
[09:33:26] <veverak> also having some system that sucks out the stuff directly from drill works
[09:33:28] <maiden> i do no fancy 3d milling
[09:33:31] <veverak> but not perfect :/
[09:33:49] * veverak would appreciate something that could mill PCBS
[09:34:12] <veverak> but completely, make paths in copper with one tool and with another tool make holes and shape of the boad
[09:34:21] <maiden> and are you using a vacuum table then things tend to get attached to that :p
[09:34:24] <veverak> could be nice for small robots (where you can use PCB as construction element)
[09:35:00] <veverak> P.S; of course not something for small SMD parts....
[09:35:02] <maiden> i saw an awesome example of that recently
[09:35:06] <maiden> will show you
[09:35:23] * veverak believes that 2030 with proper spindle could be awesome for that
[09:36:08] <deshipu> veverak: the problem with milling pcbs is that the tool that is good for copper gets damaged by the laminate
[09:36:15] <veverak> deshipu: I know
[09:36:19] <deshipu> veverak: so you need to have very good leveling
[09:36:24] <veverak> which brings high demands on the machine
[09:36:30] <veverak> yeah, because of leveling :)
[09:36:44] <veverak> deshipu: we made quite nice leveling compesation for that in hackerspace
[09:36:55] <maiden> veverak: look at this:
https://www.youtube.com/watch?v=TZNUh4EZiAU
[09:36:57] <veverak> SW that gets command for CNC and "bends" them based on leveling
[09:37:05] <jhylands> the ideal way to level the work surface is to mill it flat
[09:37:17] <veverak> made simulation on 'readings' that were made with sin/cos
[09:37:29] <veverak> yeah, I would much prefer if such correction weren't needed...
[09:37:33] <deshipu> jhylands: reminds me of that joke about automatic shaving machine
[09:37:50] <veverak> maiden: EXACTLY
[09:37:53] <veverak> :D
[09:37:59] <deshipu> jhylands: "but you didn't anticipate that different people have different faces"
[09:38:02] <jhylands> I never ended up needing to level the Sherline
[09:38:03] <maiden> veverak:
http://home.ctlnet.com/~minimechadon/minimechadon.htm
[09:38:06] <maiden> more info
[09:38:06] <deshipu> jhylands: "only before the first shave!"
[09:39:01] <veverak> maiden: awesome
[09:39:09] <maiden> this is his big one:
http://home.ctlnet.com/~mechadon/mechadon.htm
[09:39:21] <maiden> i mean: " The "brain" is a parallel processing system using thirteen PIC16F84's"
[09:39:27] <maiden> this guy is my hero
[09:39:45] <veverak> nah
[09:39:51] <veverak> why this stuff is .... so hard to find usually?
[09:39:54] <veverak> :/
[09:40:09] <veverak> meantime I should too psot my thing on the internetz I suppose
[09:40:43] <jhylands> I wrote a compiler for the 16F84 a long time ago
[09:41:53] <deshipu> veverak: hackaday.io is convenient
[09:42:02] <veverak> yeah
[09:42:11] * veverak finally finished ROS enviroment needed for tote
[09:42:40] <veverak> and could write a line or two about how to properly set distcc so everything is much faster
[09:42:53] <veverak> (and in case of A+, without distcc you can't compile everything in first place)
[09:43:00] <veverak> after exams are finished :)
[11:49:28] <weeepy> anyone here own an ili9341 screen?
[12:13:51] <robotustra> hey
[12:19:09] <robotustra> silence
[12:19:19] <veverak> is golden
[12:19:21] <veverak> :)
[12:19:37] <robotustra> mining gold?
[13:19:08] <veverak> http://www.mini-kossel.com/pi-camera-module
[13:19:10] <veverak> hmm
[13:19:15] * veverak doesn't get how are the lights powered
[13:32:28] <SpeedEvil> from thepi
[13:35:56] <veverak> so there are contacts in the screws?
[13:36:02] * veverak doesn't see the wire
[13:36:04] <veverak> :)
[14:05:34] <student> hi
[14:06:17] <student> is any one active
[14:06:33] <deshipu> no
[14:06:42] <deshipu> why?
[14:07:13] <jhylands> we're all dead
[14:07:26] <student> i see that
[14:12:00] <student> are you undead
[14:13:13] <student> bye
[14:13:44] <jhylands> well, that was very enlightening
[14:28:54] <deshipu> exteremely
[14:46:32] <student> hello
[14:50:05] <deshipu> it's you again
[14:50:19] <deshipu> who sent you?
[14:53:09] <student> aliens from galiga
[14:53:27] <deshipu> tell us everything
[14:53:29] <vicarion> how many fingers do they have?
[14:53:57] <deshipu> and where do they keep them
[14:54:02] <vicarion> also, is there a place on irc where optics experts hang out?
[14:55:36] <deshipu> #astronomy perhaps?
[14:55:49] <student> 22, in prisons called ships, no
[14:56:10] <vicarion> thanks, i'll give it a try
[14:56:58] <student> got to go back to my home planet bye

[17:15:58] <veverak> :)
[17:16:49] <veverak> also that hexa on video is sweet

http://j.mp/1SvbKY1
[17:19:17] <veverak> well
[17:19:19] <veverak> except that price
[17:19:22] <veverak> nah
[17:19:47] <DagoRed> veverak: It's not that great IMO. Anyone can do that but if you want it off the shelf it's not bad.
[17:20:00] <veverak> yeah, not worth it I suppose
[17:20:18] <veverak> and I suppose with 3d printed I can get somethign that got better feelings in hand
[17:20:22] <veverak> or... you know what I mean
[17:20:28] <DagoRed> Its one of the those projects that would be more fun to build than anything.
[17:20:37] <DagoRed> Yeah I got you.
[17:20:44] <veverak> yeah
[17:20:53] <veverak> my main problem is that like always
[17:21:00] <veverak> I would figure out what I want after I would build it
[17:21:02] <veverak> nah
[17:22:03] <veverak> but that idea with 4 joystick could be nice
[17:22:50] <veverak> https://www.sparkfun.com/products/9426 but I was thinking more about something like this
[17:23:02] <DagoRed> Then build one. You can do with an atmel easy.
[17:23:22] <veverak> yeah, been thinking about it :)
[17:23:36] <deshipu> veverak: somehow i never used xbee
[17:23:53] <DagoRed> Propeller can do some really cool things with their uC's though.
[17:24:24] <veverak> deshipu: yeah, that's another thing... :)
[17:24:30] * veverak wonders how esp could work
[17:25:32] <deshipu> veverak: or that nrf thing
[17:25:43] <deshipu> never used that either
[17:26:00] <deshipu> veverak: I have two of those psp joysticks
[17:27:30] * veverak always wondered if it woudln't be better to have those on backside
[17:27:51] <deshipu> then it would be invesed
[17:28:07] <veverak> just question of getting used to it
[17:28:16] <veverak> and as one that raced with rc cars, it's not so much hassle
[17:28:18] <veverak> :)
[17:28:21] <deshipu> for rc models you would always "pinch" them anyways
[17:28:27] <deshipu> thumbs are no good for precision
[17:28:48] <veverak> yeah
[17:28:51] <veverak> exactly
[17:29:05] <veverak> and if it would be on backside, it would be easier to use different fingers
[17:29:06] <deshipu> maybe even put them on the "shoulders"?
[17:29:07] <veverak> :)
[17:29:15] <veverak> maybe?
[17:29:54] <deshipu> you are the one with 3d printer, experiment!
[17:30:00] <veverak> true to that
[19:27:46] <jazzdisliker> hey, i have an ili9341 screen that isn't working. i'm interfacing it with a teensy 3.2 and it won't display anything but "Waiting for Arduino Serial Monitor..."
[19:28:31] <rue_house> dunno
[20:36:50] <anonnumberanon> Man I would love to take this class:
http://lambda.ee/w/images/a/ae/Rtos_01.pdf
[21:24:09] <rue_house> so far most of this is just basic C programming
