03:24 Jak_o_Shadows hi
03:24 aemquo Up to much?
03:25 Tom_itx 6'1"
03:25 aemquo hue
03:55 Fiesta does anyone here know about springs
03:56 Tom_itx they bounce
03:56 Fiesta i'm curious to know what type of spring would be best suited to just storing energy. It seems those wound clock springs are mostly used for this.
03:56 Fiesta but i need something... big
03:56 Tom_itx seems so
03:56 Tom_itx also used in lawnmower recoil
03:56 Fiesta and i don't think they make clocks that big
03:56 Tom_itx tape measures
03:56 Tom_itx etc
03:57 Fiesta biggest one's i've yet found are Quill springs for drill presses, i think they are used to raise the weight of the drill back up after you let go of the handle
03:57 Tom_itx yup
03:58 Fiesta but even bigger would be nice
03:58 Tom_itx steal one off Big Ben
03:59 Fiesta ok
03:59 Fiesta I'm tryign to figure out what would make a good 3D printable battery
04:00 Fiesta actually printing a spring would likely have terrible quality, better to use any steel spring i reckon
04:00 aemquo 3D print a spring? Yeah that would break in seconds.
04:00 Fiesta yeah
04:00 Fiesta so... some existing spring, encased in a 3D printed gear-box.
04:00 Fiesta car springs could be interesting
04:01 Fiesta but you'd need a lot of plastic around it to make it not explode your aparatus
04:03 Fiesta i can't find any reasonable quantity of "wave springs" on ebay. But a stack of belleville washers could be promicing.
04:04 Fiesta http://www.smalley.com/wave_springs/about_springs.asp these are wave springs, they are apparently better than coil springs.
04:04 Fiesta https://en.wikipedia.org/wiki/Belleville_washer and a relevatnt link for belleville washers
04:05 Fiesta my head is spinning with springs :S
04:07 Fiesta need an expert to hold my hand :)
04:07 GargantuaSauce Fiesta: look into flywheel energy storage
04:07 GargantuaSauce i think that's a lot more approachable than a spring
04:08 Fiesta i'm worried about wobble and frictional losses with that
04:08 GargantuaSauce much much easier to convert the stored energy back to electricity though
04:10 Fiesta hmm.... wonder if a bag of water could finction as a flywheel.
04:10 Fiesta *function
04:10 GargantuaSauce also you're not going to 3d print something that has the strength to hold in a spring holding an appreciable amount of energy
04:11 Fiesta yeah. the car-spring idea makes me nervous
04:11 Fiesta if it's to work, it may need extra steel vitamin parts other than the spring, just for leaverage, to get the forces down to a level manageable with printed plastic
04:12 Fiesta like... steel cables and pulleys or something.
04:12 GargantuaSauce i would be very worried about heat also
04:12 Fiesta heat from a car spring?
04:12 Fiesta oh, from all the gears
04:12 GargantuaSauce springs heat up too
04:13 GargantuaSauce you're storing energy with this thing
04:13 Fiesta i didn't know that
04:13 GargantuaSauce it won't be 100% efficient
04:13 GargantuaSauce all the energy lost will be dissipated as heat
04:13 GargantuaSauce as soon as it hits 80C or so the strength of the plastic is an order of magnitude lower
04:13 GargantuaSauce a bit higher for ABS but you get the point
04:13 Fiesta urgh
04:14 GargantuaSauce why can't you just use a battery?
04:14 Fiesta this is a battery
04:14 GargantuaSauce a chemical battery
04:15 Fiesta coz it can't be 3d printed
04:15 Fiesta well... easily
04:15 Fiesta i saw a design printed for zinc-air batteries, but ... meh
04:16 GargantuaSauce so you're just doing as masturbatory exercise to do something with 3d printing that can be done much better via other means?
04:16 GargantuaSauce i mean i can get behind that, just making sure we're on the same page
04:17 GargantuaSauce you aren't going to beat the power/energy density and reliability of a chemical battery without some serious long-term development (and probably more refined manufacturing)
04:20 Fiesta__ <GargantuaSauce> a chemical battery<Fiesta> coz it can't be 3d printed<Fiesta> well... easily<Fiesta> i saw a design printed for zinc-air batteries, but ... meh<Fiesta> you know the whole 3d printer aesthetic. Make something mechanical so that it can be made with a 3d printer, just.. uh... coz<Fiesta> it's hard to resist
04:20 Fiesta__ whoops, formatting killed that
04:20 GargantuaSauce <GargantuaSauce> so you're just doing as masturbatory exercise to do something with 3d printing that can be done much better via other means?
04:20 GargantuaSauce <GargantuaSauce> i mean i can get behind that, just making sure we're on the same page
04:20 GargantuaSauce <GargantuaSauce> you aren't going to beat the power/energy density and reliability of a chemical battery without some serious long-term development (and probably more refined manufacturing)
04:21 GargantuaSauce do you own a 3d printer?
04:21 Fiesta no
04:22 GargantuaSauce the properties and quality of their prints are much less amazing than what I believe your perspective on the matter is
04:22 Fiesta i'm pretty familiar with 3d printers
04:22 Fiesta i just don't have much need for one
04:22 GargantuaSauce i don't think the thermoplastics have the required durability for this sort of application
04:23 GargantuaSauce (where the energy density even vaguely rivals that of a chemical battery)
04:23 Fiesta indeed. It would be an interesting to know how large it needs to be to be useful.
04:24 GargantuaSauce it's more a question of small.
04:27 Fiesta internet is flakey lately
04:27 Fiesta <GargantuaSauce> i don't think the thermoplastics have the required durability for this sort of application<Fiesta> indeed. It would be an interesting to know how large it needs to be to be useful.
04:27 GargantuaSauce <GargantuaSauce> it's more a question of small.
04:27 Fiesta hmm?
04:27 GargantuaSauce as in it needs to have enough energy and power density to be able to move itself and some other stuff, right?
04:28 GargantuaSauce if it's huge and barely cranks out any work then it's absolutely useless
04:29 Fiesta i'll probably be storing energy from windpower
04:29 Fiesta thus the mechanical
04:29 Fiesta or maybe solar stirling (still mechanical)
04:29 Fiesta that way it'll be a fully 3d printed energy collection and storage device
04:30 GargantuaSauce how about pumping water into a raised reservoir?
04:30 Fiesta with few (if any) vitamin parts
04:30 Fiesta yeah that's another option
04:30 Fiesta a tall structure/pole will make the thing rather large though.
04:31 GargantuaSauce well if there's already a wind turbine sitting on one...
04:31 Fiesta i figure there's gravity (ie: water pumping, or hoisting), compressed air, elastic (spring), flywheel.
04:32 GargantuaSauce most of those are pretty infeasible for an all-extruded mechanism
04:34 Fiesta (wow this is annoying)
04:35 Fiesta <GargantuaSauce> well if there's already a wind turbine sitting on one...<Fiesta> i figure there's gravity (ie: water pumping, or hoisting), compressed air, elastic (spring), flywheel.<Fiesta> and temperature differentials (ie: separate tanks of hot water, and ice)
04:35 Fiesta good point about the turbine pole
04:35 GargantuaSauce most of those are pretty infeasible for an all-extruded mechanism
04:35 Fiesta you think so?
04:37 GargantuaSauce well i guess it's mostly achieving a reasonable degree of efficiency that i think is infeasible
04:37 Fiesta <GargantuaSauce> most of those are pretty infeasible for an all-extruded mechanism<Fiesta> you think so?
04:37 GargantuaSauce there are major mechanical limitations to 3d printed parts
04:38 GargantuaSauce like you can't get a flat surface
04:38 GargantuaSauce i have yet to see a design for a bearing that won't wear out super fast
04:39 Fiesta 3d printed parts have flat surfaces on their base
04:39 GargantuaSauce yes ok one single *mostly* flat surface
04:39 GargantuaSauce if you have a reciprocating pump or stirling engine or whatever, either you have a significant gap between piston and cylinder, or they grind against each other
04:47 GargantuaSauce people seem to idolize the idea of all-printed mechanisms but the way i see it, that's a step backwards. a huge part of the concept of engineering a mechanism is leveraging the advantages of multiple materials
04:47 GargantuaSauce that's not to say i dislike the idea of one-step manufacturing
04:48 Fiesta consumer 3d printers have a long way to go
04:48 GargantuaSauce but it's a huge pipe dream until we figure out how to actually do heterogeneous prints with multiple processes
04:48 GargantuaSauce and FDM simply is not suitable for a lot of mechanisms
04:50 GargantuaSauce if you are really serious about doing this stuff without chemical batteries (which i maintain is the best solution at a sub-10kW or so scale) i would suggest approaching it with machined aluminium as the primary medium
04:51 Fiesta hmm
04:51 GargantuaSauce because you can actually make parts that seal
05:10 GargantuaSauce https://www.gcsurplus.ca/mn-eng.cfm?snc=wfsav&sc=enc-bid&scn=149227&lcn=294472&lct=L&srchtype=&lci=&str=51&ltnf=1&frmsr=1&sf=ferm-clos
05:10 GargantuaSauce wish i had a truck
12:08 armyofevilrobots Holy. Gamechanger. http://markforged.com/
12:23 aemquo ... ( ._.) wat.
13:33 GuShH_ armyofevilrobots: it would be a game changer if it were cheap cheap cheap
13:33 GuShH_ it all exists, at a cost.
13:38 i-make-robots finally finished the next version of my delta robot: http://www.marginallyclever.com/shop/index.php?main_page=product_info&cPath=9&products_id=83
13:38 i-make-robots anyone here have experience with cross roller bearings?
13:49 adam789654213 i-make-robots: wow... that's a serious looking piece of equimpment. What does it do?
13:53 adam789654213 i-make-robots: i am wondering about the mechanics (motion generation techniques used) of the device, to figure what it would do
13:53 Skwint yeah ... that's an odd page ... you can download it, buy it, show interest in it, and look at it, but I've no idea what it does
13:54 GuShH_ adam789654213: mostly used for plastic extrusion / 3d printing (all the rage)
13:54 GuShH_ Skwint : likewise. however you can attach a pen or a cutter and use it as a plotter
13:55 GuShH_ I just wouldn't use wood.
13:55 GuShH_ looks like ply
13:55 Skwint I was thinking about 3D printing
13:55 GuShH_ laser cut or not, it's prone to changes with humidity, temperature, etc.
13:55 Skwint and pondering cutting sheets and sticking them together instead of printing molten plastic
13:55 Skwint then you could print a sheet of metal in the midle, like alumninium foil, to print circuit boards into it
13:56 adam789654213 that is awsome. and there is a link to the assembly instructions
13:56 adam789654213 http://learn.marginallyclever.com/index.php/Delta_Robot_3
13:56 GuShH_ that works... but registering each layer could be a challenge
13:56 GuShH_ and bonding
13:56 adam789654213 fricken cool!!!!!!!!
13:56 Skwint the bonding is an issue
13:56 GuShH_ adam789654213: #reprap
13:56 Skwint the other thought I had was to work on a much bigger scale and use papier mache ;)
13:56 GuShH_ that's just a blank skeleton you need about 800 bucks on top heh
13:56 i-make-robots adam789654213: the source is open, it should be linked from that page.
13:57 i-make-robots GuShH_: also pick & place. food assembly.
13:57 GuShH_ not so much
13:57 i-make-robots the number one thing people buy it for is iphone game testing and password cracking (try every combination)
13:57 i-make-robots GuShH_: in industrial food processing deltas are very popular. this model is, of course, scaled down.
13:57 GuShH_ the best way I can think of to describe how the motion of a delta works... a marionette.
13:57 Skwint wouldn't that be easier with a moving beam like a scanner?
13:58 i-make-robots Skwint: depends on the location, application, etc. the head of a delta is really realy light, which can often get you faster movement.
13:58 i-make-robots no need to move the whole beam.
13:58 Skwint yeah, I'm thinking it through and it's only easier to design - once you have a design it's probably worse
13:58 Skwint I still want to make something that cuts sheets
13:59 i-make-robots i build these because (a) people want to take them apart and learn and (b) nobody else offers one with a visible price tag. they're all "call for a quote".
13:59 Skwint paper would be too thin and would curl up
13:59 Skwint card and spray on glue perhaps?
13:59 ShH_ sh
13:59 Skwint 3D printer plastic is expensive!
13:59 GuShH_ it shouldn't be
13:59 adam789654213 i found a google video on the mechanics of the delta robot in food proccessing: https://www.youtube.com/watch?v=_hwWt3n-f5A
13:59 Skwint making a cheap alternative for throw away objects would be interesting
13:59 GuShH_ but where there is hype there is inflation
13:59 wint
13:59 i-make-robots Skwint: buy it in pellets and get an filament recycler.
14:00 adam789654213 wonder why its called a "delta robot"
14:00 GuShH_ abs is cheap as dirt, as a raw material.
14:00 GuShH_ similarly with pla
14:00 i-make-robots then when your prints are no good you can turn them back into filament.
14:00 i-make-robots i have two 3d printers and buckets of old prints, i just bought a recycler so ask me again in a few weeks and I'll let you know how it goes.
14:00 GuShH_ at the expense of time and electricity
14:01 GuShH_ "now I have to babysit another machine!"
14:02 i-make-robots here's a whole playlist of deltas: https://www.youtube.com/playlist?list=PLCA2D16A480CD47BE&feature=mh_lolz
14:03 Skwint do we still tend to surround the object in powder to hold it up while it's printed?
14:03 wint is out of date on 3D prin
14:03 GuShH_ Skwint: some are using hot beds, others are using abs glue, others are using HAIR SPRAY (...) and whatnot, elmers glue perhaps
14:04 GuShH_ of course abs glue for abs printing.
14:04 GuShH_ sorry the kids are calling it "juice"
14:04 GuShH_ it's technically an adhesive, because it's been suspended in a solvent (acetone).
14:05 Skwint well, one construction material we have an abundance of is sea salt, if we want something suspended in a solvent :p
14:05 GuShH_ but is it kosher?
14:05 ShH_ bl
14:05 Skwint it might be fun to have a robot that 3D prints giant salt statues on the beach
14:05 i-make-robots i'm a big fan of the HIPS/ABS combo, tho I have yet to try it myself.
14:06 GuShH_ Skwint: even more fun engineering it with no ferrous materials
14:06 i-make-robots High Impact Polystyrene is basically styrofoam. it can be recycled like ABS and it dissolves in limonene. so use HIPS as a support structure to make really fancy prints.
14:06 GuShH_ no stable platform...
14:06 GuShH_ no obvious power source other than sunlight
14:07 i-make-robots pritning on the beach you say? http://www.youtube.com/watch?v=6ajzOaauYa4
14:07 GuShH_ or wind.. which isn't as abundant
14:08 GuShH_ I hope all 3druggies move to the desert
14:08 GuShH_ oh look four fresnel lenses and what looks to be a 30-40W solar panel...
14:08 GuShH_ oh it's one supported with a cross member
14:09 GuShH_ looks like another guy with a blown gasket.
14:11 i-make-robots it's only crazy until someone succeeds.
14:11 GuShH_ i-make-robots: too much babysitting, again.
14:15 GuShH_ it's not success until it's fully autonomous
14:20 i-make-robots we only differ on the definition of success.
14:22 GuShH_ i-make-robots: do you like coffee?
14:22 SquirrelCZECH well
14:22 SquirrelCZECH it looks like interesting concept
14:22 SquirrelCZECH question if usable :)
14:22 GuShH_ you need to employ someone to throw the sand on top and level it down between layers
14:23 ShH_ chuc
14:23 GuShH_ SquirrelCZECH: I wonder what exactly defines the thickness of each layer, you can't change the focal point without spreading -less- heat around
14:24 SquirrelCZECH GuShH_: I assume you should be able to create autonomous thingy for layers
14:24 GuShH_ it can't just be speed induced, but that has to have a role in bonding each layer
14:24 SquirrelCZECH and math around it
14:24 SquirrelCZECH so it would be proper....
14:24 GuShH_ sure
14:25 SquirrelCZECH but just know for me it seems it's good enough to use it as "prove of concept"
14:25 GuShH_ barrel full of sand, solenoid to actuate the gate let gravity do it's thing... but a gantry just to move the leveler is quite an expense
14:25 SquirrelCZECH because it's obvious that with another research it would get MUCH better results
14:25 GuShH_ and figuring out the amount of sand required, of course you could lower the floor and always fill to the rim
14:26 GuShH_ that video is 2 years old
14:26 GuShH_ I'd like to see the current version if any
14:26 SquirrelCZECH wow :)
14:27 GuShH_ damn adobe... to install one of their products you must close their other products
14:27 ShH_ is reinstalling some cs2
14:32 i-make-robots GuShH_: I haven't made up my mind about coffee yet.
14:33 GuShH_ adobe once let cs2 escape on a brainfart, I don't believe it was intentionally left out to the public...
14:33 GuShH_ but hey their fault.
14:33 GuShH_ i-make-robots: oh? tea then?
14:33 i-make-robots where is this going?
14:33 GuShH_ I know they're on CS6 or higher, I just can't afford the full suite.
14:33 GuShH_ i-make-robots: are you human?
14:33 i-make-robots you'll have to take my word for it.
14:33 GuShH_ haha
14:34 GuShH_ i-make-robots: trying to find common ground aside from bolts and nuts.
14:34 GuShH_ hi KongfuPanda
14:36 i-make-robots i'm a huge cinemaphile.
14:37 i-make-robots i mean "avid", not "fat".
14:37 i-make-robots erm… I'm a homeowner and I'm starting my third business.
14:37 i-make-robots i like planetary annihilation tho I have yet to smash anyone's planet with an asteroid, which is the one thing I was looking forward to.
14:40 i-make-robots and I really really liked https://www.youtube.com/watch?v=_WYs3Xxh3XE
14:45 ShH_ frowns at i-make-ro
14:45 i-make-robots what?
14:45 GuShH_ asteroids... they made a game about that you know.
14:53 i-make-robots yes, but in PA you can drop the asteroid on someone else.
18:21 GuShH_ recaptcha is now using signs and other google street view related imagery? like the street address on every place and whatnot...
18:22 GargantuaSauce yeah and has been for like over a year
19:05 GuShH_ GargantuaSauce: I didn't pay attention, is it for google map / streetview?
19:05 GargantuaSauce i think that image is usually the 'known' one
19:05 GuShH_ how come the address of your place is not considered private but the license plate on your car is? what's the difference? both are on public display, both are belonging to your property
19:05 GuShH_ nah it has to be the other one, which looks generated
19:06 GuShH_ in the case of the license or the address you can find out who lives there either way...
19:06 GargantuaSauce good point
19:06 GuShH_ similarly to a land line
19:06 GargantuaSauce and yeah the privacy stuff is kind of bullsiht
19:06 GuShH_ unless you paid not to show up
19:06 GuShH_ I get the face-blurring, that's ok...
19:07 GargantuaSauce i really like it when the face detection gets a false positive
19:07 GuShH_ lol
19:08 GuShH_ why don't they use the technology to find out if the license plates are red-flagged, if they are improperly installed or partially covered (which is illegal where I live)... I know they only drive around the block once in a long while, but they do have plenty of good data to work with...
19:08 GuShH_ are they afraid people will start throwing rocks at them? I thought they were already doing that in some places...
19:09 GuShH_ "not the scope of the project" yet they've been comercially doing it inside stores and whatnot. they could sell the information if they wanted to.
19:09 GargantuaSauce the streetview images for my area are 4 years old
19:10 GuShH_ it's a neat concept but outdated data is almost as bad as no data for me
19:10 GargantuaSauce and i'm sure the american authorities have access to the originals
19:10 GargantuaSauce so if they wanted to do such a thing they could. easily.
19:11 GuShH_ I'm not sure about the current state of technology in our cctv grid... I think they have face recognition and other facilities, but not sure if they can track flagged cars
19:11 GargantuaSauce god damn i shouldn't have started looking around town on streetview
19:11 GuShH_ there's also no point in having security cameras if there isn't someone looking, or at least software smart enough to detect what needs to be looked after...
19:11 GargantuaSauce makes me wish it was summer
19:12 GuShH_ I used to know the location of every camera in my zone
19:12 GuShH_ now that I moved I'm clueless as to where they are exactly
19:12 GuShH_ the domes are hd and the zoom is good for 2 blocks
19:13 GuShH_ but there's always an obstruction
19:13 GuShH_ reminds me of the truman show
19:15 GuShH_ the fools decided not to install protective cages around the cameras because it would "diminish the image quality" and thus people have vandalized quite a few ever since
19:15 GargantuaSauce a little black spraypaint goes a long way
19:15 GuShH_ too high up
19:15 GuShH_ paintball marker works though
19:15 GuShH_ lasers, rocks..
19:15 GuShH_ I need to point a laser at the photocell for the street lights so I can control them at night!
19:16 GuShH_ it's actually aimed sideways, not up.
19:16 ShH_ g
19:16 GargantuaSauce the ones here point up and are thus susceptible to bird shit
19:17 GargantuaSauce https://maps.google.ca/?ll=46.235756,-63.12705&spn=0.001555,0.003782&t=h&z=19&layer=c&cbll=46.235824,-63.127138&panoid=BS6bNJ1sD5P54YghDhBfeQ&cbp=12,92.7,,0,9.75
19:17 GargantuaSauce hubcaps blurred for privacy
19:17 GuShH_ haha
19:28 GuShH_ GargantuaSauce: maybe they are not false detections, there ought to be crazies out there threatening to sue Google over nonsense.
19:28 GargantuaSauce nah if you move in either direction they're clear again
19:28 GuShH_ "MY UNDERWEAR SHOWS UP BLUR IT OR ELSE"
19:29 GuShH_ Do they have ass-crack-detection?
19:29 Tom_itx the best
19:29 GargantuaSauce maybe if someone's ass looks like a face
19:29 GuShH_ what if two persons from the same sex are kissing and it offends a certain bigot?
19:29 Tom_itx watching a couple videos on scraping
19:29 GuShH_ GargantuaSauce: we have the technology to make that a reality!
19:30 GuShH_ Tom_itx: scraping poop?
19:30 Tom_itx ways
19:30 Tom_itx dumb shit
19:30 GuShH_ what
19:30 GuShH_ I may be dumb at times but not shit!
19:30 ShH_ kicks Tom_itx's c
19:30 m_itx blur
19:31 ShH_ unblur
19:31 rgantuaSauce adds wax paper to his gla
19:31 GargantuaSauce privacy filters installed
19:31 GuShH_ new tax on motorcycles, increases prices over 30%
19:31 GuShH_ stupid country
19:31 Tom_itx gotta balance out the gas savings
19:32 ShH_ draws a hairy dong on the wax p
19:32 GuShH_ I don't have gas savings actually
19:32 GuShH_ I paid twice as much as last year, used a bit less
19:32 Tom_itx they knew you weren't using enough
19:32 GuShH_ hah I think they have "differential" pricing
19:33 GuShH_ if you own a pool or a big house they charge you more
19:33 GuShH_ ...
19:33 GuShH_ I suspect the meter is bad, but they never came to check it
19:33 GuShH_ Also my phone line got swapped with the neighbours
19:33 GuShH_ next house.
19:33 GuShH_ after the storm a lot of the wiring got damaged, some telco "tech" mixed up the pairs...
19:34 GuShH_ still waiting for them to come and fix it
19:34 GuShH_ if I get up there I'll cut all the pairs but mine, I swear I'll do it.
19:34 GuShH_ oh wait, they'll find out...
19:34 GuShH_ all the pairs but a few of them! there, better. <evillaugh>
19:35 GuShH_ wouldn't you love to have me as your neighbour, Tom_itx?
19:35 Tom_itx i keep my neighbors in order
19:35 GargantuaSauce i would, we could build robots together!
19:35 GuShH_ I actually fear she (the neighbour) will start calling relatives from Spain and who knows where, then all the charges will go to MY account
19:36 Tom_itx what's her number?
19:36 GuShH_ GargantuaSauce: lies you would have me as your machinist slave and take all the credit!
19:36 GuShH_ now it's mine
19:36 GargantuaSauce that's what i said
19:36 GuShH_ But I'm not calling anyone with her line...
19:36 Tom_itx sure he's good enough?
19:36 GargantuaSauce better than me
19:36 Tom_itx heh
19:36 GuShH_ I can learn dammit
19:36 GuShH_ You have no faith in me!
19:36 ShH_ runs upstairs and slams the door
19:36 Tom_itx you ever try that skill?
19:37 Tom_itx scraping?
19:37 GuShH_ No, I'm not a fitter.
19:37 GargantuaSauce actually i've decided that what i need is a nemesis
19:37 Tom_itx you're not fit?
19:37 GuShH_ But you could say I scraped that chuck arbor
19:37 GuShH_ I'm not perfectly fit no.
19:38 GuShH_ Tom_itx: what are you trying to match?
19:38 Tom_itx i'd have to get some stuff before i could do it
19:38 GuShH_ or fit...
19:38 Tom_itx nothing
19:38 GuShH_ you can improvise
19:38 Tom_itx i was bored
19:38 GuShH_ You crazy you.
19:38 Tom_itx it was pretty interesting though
19:38 GuShH_ I had to scrape the top-end of a 26cc 2 stroke engine once, I removed the gasket but the surfaces were not mating properly
19:39 GuShH_ aluminum, you can scrape it with a spoon, almost.
19:39 GuShH_ I used a high temperature gasket "maker" but I wanted the surfaces to mate properly first, because OCD.
19:40 GuShH_ I don't know if it's lack of practice or if it really is an almost never ending story, but once you remove the high spots even more show up, and more, and more!
19:40 GargantuaSauce gasket maker revolution
19:40 GuShH_ that stuff can do more harm than good if you use too much
19:40 GuShH_ or use it in the wrong places
19:41 GuShH_ http://www.youtube.com/watch?v=Ow_mBbd2jWU haha
19:41 GuShH_ rue_house: now if you could only parallel about 30.000 of those... you could power your truck!
19:42 GuShH_ balloons... junk food... lolipops... thread... this assumes you are married with kids! I'm not!
19:43 adam789654123 cool link to the stirling engine. never heard of it before
19:44 GuShH_ adam789654123: the parts list is way bigger than making one out of metal
19:44 GuShH_ >_<
19:44 GargantuaSauce you can improvise all sorts of cool stuff when you don't limit yourself to thermoplastic-only
19:44 GargantuaSauce cough fiesta
19:44 adam789654123 well, even just watching i bet ill get some ideas
19:45 GuShH_ Is there a healthy alternative to salt?
19:45 GuShH_ GargantuaSauce: I'm not good with arts and crafts ....
19:45 adam789654123 lemon and lime, mixed
19:45 GargantuaSauce salt is much less bad for you than people make it out to be
19:46 GuShH_ I think school scarred me with all that.
19:46 adam789654123 or just lemon and lime i guess
19:47 GuShH_ hey now he's using a big c-clamp, that's not something kids have!
19:47 adam789654123 i used to put a bunch of lemon on everything, and i thought it was great
19:47 GuShH_ they also say acids are bad for ya
19:47 adam789654123 starting to sound like one of those learn to program in 21 days books
19:47 Tom_itx everything is bad for ya
19:47 GuShH_ GargantuaSauce: hypertension surely has something to do with salt intake
19:48 GuShH_ Tom_itx: only in excess
19:48 GuShH_ and I do like a lot of salt.
19:48 GuShH_ spices are not enough!
19:48 adam789654123 me neither. makes we want to drink gallons of water
19:48 adam789654123 i dont like too much salt
19:48 GuShH_ well not that much, but more than average.
19:49 adam789654123 balamic vineger?
19:49 GuShH_ now he's using a tiny miter box! that's also kids don't have!
19:49 GargantuaSauce i think artrosclerosis is a much bigger factor
19:49 adam789654123 balsamic?
19:49 adam789654123 then hypertension?
19:49 adam789654123 something like 1 out of every 3 deaths is from a heartattack
19:49 GargantuaSauce than sodium intake as a precursor to chronic hypertension
19:50 GuShH_ adam789654123: we need redundant hearts
19:50 GuShH_ would it take that much more energy to have two hearts?
19:50 adam789654123 http://www.cdc.gov/heartdisease/facts.htm
19:50 adam789654123 in the us, 1 out of every 4 deaths
19:50 GuShH_ but in the US they eat like pigs...
19:51 adam789654123 you need to make one
19:51 adam789654123 well....
19:51 adam789654123 but still...
19:52 GuShH_ one sec... natural event, must photograph
19:53 adam789654123 peeping tom
19:55 am789654123 has a strange sense of humor somet
20:00 GuShH_ adam789654123: no, flowers.
20:00 GuShH_ let's see if you are aware of the one and possibly only flower that blossoms at night, once a year.
20:01 GuShH_ and smells better than any other flower.
20:01 adam789654123 hmmm
20:01 adam789654123 there was a flower that bloomed at night
20:01 GuShH_ then the flower dies off.
20:01 adam789654123 that i was aware of
20:01 adam789654123 but not once though
20:01 adam789654123 there was a season for it
20:01 adam789654123 dont remembor what they where called though
20:02 adam789654123 what is it called?
20:02 GuShH_ one sec looking at the pics I took
20:02 GuShH_ gah I need a wifi camera
20:02 adam789654123 np
20:03 adam789654123 take your time
20:05 GuShH_ adam789654123: alright it's "Epiphyllum oxypetalum" (I had to look it up)
20:07 GuShH_ http://gushh.net/tmp/dscn5057f.jpg
20:08 GuShH_ http://gushh.net/tmp/dscn5064f.jpg
20:08 GuShH_ freaky cactus is freaky.
20:10 GuShH_ looks nicer by the moonlight...
20:10 adam789654123 beautiful flower. you using a mobil device for irc?
20:10 GuShH_ sometimes
20:10 adam789654123 ok
20:11 GuShH_ why? heh
20:11 GuShH_ when I'm trying to do 10 things at the same time I end up taking 10 times as long...
20:11 adam789654123 because you were interested in this flower while on irc
20:11 adam789654123 so im trying to picture it
20:12 GuShH_ lol
20:12 adam789654123 your walkin around outside, chatting, and you spot the flower
20:12 GuShH_ sometimes I trip over.
20:12 adam789654123 and snap a picture, probably out of the same device your chatting with
20:12 GuShH_ Not this time!
20:12 adam789654123 :)
20:13 GuShH_ my tablet doesn't have an led for a "flash"
20:13 adam789654123 i own a tracfone
20:13 adam789654123 that and gps is all for mobil devices
20:13 GuShH_ I recently started developing for android...
20:13 adam789654123 i dont think i can get into that
20:13 GuShH_ why not?
20:14 GuShH_ It involves Java, goes against everything I stand for.
20:14 adam789654123 im more into something like the nano
20:14 adam789654123 ben nanonote
20:14 GuShH_ I might end up sticking with this silly multi-target language, even if it constricts me
20:14 adam789654123 http://en.qi-hardware.com/wiki/Ben_NanoNote
20:14 adam789654123 straight up, java sucks
20:14 GuShH_ it still requires all of the native tools to be installed
20:15 GuShH_ (monkey-x)
20:15 adam789654123 ive used it for 4 years
20:15 GuShH_ I don't know why Java still exists
20:15 adam789654123 and its terrible
20:15 GuShH_ It ties up the world with electrical tape and wire, Java.
20:15 adam789654123 because it serves a corporate purpose i think
20:15 adam789654123 basically, you can constrict programmers with it
20:15 GuShH_ Can you imagine the amount of energy that's wasted due to Java in general
20:15 adam789654123 because its to un-powerful
20:15 adam789654123 you need to plug into other things to get it do do anything
20:16 adam789654123 thats my story and im stickin too it
20:16 GuShH_ I was an assembly freak for years
20:16 adam789654123 assembly is cool
20:16 ShH_ put an end to
20:16 adam789654123 but that is definately a hobby tthing
20:16 GuShH_ I would spend days optimizing pointless functions
20:16 adam789654123 im lookin at c again though
20:17 GuShH_ It's not strictly hobby, native code is very important at the low level
20:17 adam789654123 you can do microcontroller stuff
20:17 GuShH_ specially where speed is of concern
20:17 GuShH_ I can, but mostly in C++
20:17 adam789654123 but c seems like a good choice because its portable
20:17 GuShH_ never touched avr or pic "asm"
20:17 adam789654123 ive worked with the avr
20:17 adam789654123 a bit
20:17 GuShH_ I'm not _that_ insane.
20:18 adam789654123 but it was on an arduino
20:18 adam789654123 thats their chip right?
20:18 ShH_ twit
20:18 GuShH_ GargantuaSauce: hold me before I do something bad!
20:18 GuShH_ adam789654123: yes Arduino uses AVR MCUs
20:19 adam789654123 im interested in microcontroller electronics and basic peripheral integration
20:19 adam789654123 i bet it would take an enourmous amount of work to build anything though
20:19 GuShH_ depends
20:19 adam789654123 probably an entire infastructure involved
20:20 adam789654123 but i guess you can keep tweeking and learning how you would do it better next time
20:20 adam789654123 youve done stuff with microcontrollers?
20:21 GuShH_ not much
20:21 adam789654123 anyway, they are tiny computers, which is really cool
20:21 GuShH_ more or less
20:21 MrCurious man i came in late. what are tiny computerss
20:21 adam789654123 but im thinking you should be proficient at math and logic to do low level programming
20:22 MrCurious GuShH_: fix the argentinan peso already.. 11% drop in 1 day!
20:22 Tom_itx u snooze u looze
20:22 GuShH_ MrCurious: shut the flock up.
20:22 GuShH_ MrCurious: it's not funny.
20:22 MrCurious O^o
20:22 GuShH_ I lost money due to that.
20:22 Tom_itx :O
20:22 GuShH_ I said flock, jeeze.
20:22 MrCurious buy american!
20:22 GuShH_ WE CANT
20:22 GuShH_ that's the problem!
20:22 MrCurious flockers
20:22 GuShH_ save us, I grant you permission to attack.
20:23 Tom_itx what you got we want?
20:23 MrCurious nah... may surprise you... but we dont want that bit...
20:23 GuShH_ bring the US army, shoot the bitch in the head, I'll mop up the floor so their boots won't get stained with blood.
20:23 GuShH_ MrCurious: we do have oil.
20:23 MrCurious yeah, oil... right.... we moved on...
20:23 GuShH_ lithium, despite the chileans stealing most of it
20:23 GuShH_ MrCurious: you did?
20:23 MrCurious yeah, we are all about alternative energy now
20:24 ShH_ eyero
20:24 Tom_itx yeah that was just a curious hobby
20:24 GuShH_ so you'll attack countries to steal their solar panels?
20:24 GuShH_ start with China.
20:24 Tom_itx let em poison themselves first
20:25 GuShH_ they might mutate into something you can't handle
20:26 Tom_itx gremlins?
20:26 ShH_ pokes adam78965
20:26 GuShH_ only if you feed them after midnight
20:26 Tom_itx they run on rice
20:27 adam789654123 hey GuShH_
20:28 GuShH_ let's see if I can finish my first nasty game.
20:28 adam789654123 im not following the politics of argentina
20:28 GuShH_ adam789654123: nobody is
20:28 ShH_ points at MrCur
20:28 MrCurious watching americas great leader
20:29 am789654123 is thinking `p[t]-p == (n-z-2)-(n-z-1) =
20:29 GuShH_ you can only buy green if you make over X a year, if you have no debt, if the planets are aligned just right and you can only buy 2k a month.... at 20% over the official exchange rate.... yeah whatever, someone is going to murder these assholes sooner or later, I'm just waiting.
20:30 adam789654123 well.... try to grow some food and buy local i guess
20:30 adam789654123 you got any property?
20:30 GuShH_ by green I mean USD sir.
20:31 GuShH_ not one time was I talking about food
20:31 GuShH_ currency. and the recent devaluation, on top of the already massive devaluation, inflation, bullshitation.
20:32 adam789654123 yes. i understand what you mean
20:32 adam789654123 with that anyway
20:32 GuShH_ Where are you at?
20:32 adam789654123 East Coast US
20:33 GuShH_ Bah I was hoping you were British!
20:33 adam789654123 so im saying if your money is losing value, try to prepare yourself for hard times
20:33 GuShH_ I'm hoping someone will put a quick, abrupt end to that.
20:33 adam789654123 Why, were you expecting John Cleese?
20:34 GuShH_ I wanted to argue about the falklands.
20:34 adam789654123 Oh
20:34 adam789654123 ok
20:34 GuShH_ Haha
20:34 adam789654123 which side you on, ill pick the other
20:34 GuShH_ Hey!
20:34 adam789654123 What do you think about the Falklands?
20:34 GuShH_ Back on topic.
20:34 GuShH_ No comment.
20:34 adam789654123 how can i argue with you then?
20:35 adam789654123 oh well
20:35 GuShH_ Hrmm I wonder if XML would be ideal to define origins, offsets, etc. of multiple object instances
20:35 GuShH_ hierachical objects
20:35 adam789654123 it depends on if the objects come from the sea
20:36 ShH_ raises an eye
20:36 adam789654123 but seriously, i think you can embed info however you want xml
20:36 adam789654123 basically like an information tree
20:36 GuShH_ Animation related connondrum
20:36 adam789654123 so you should be able to do that
20:36 GuShH_ Yes, but I tend to hate XML and favor JSON
20:36 adam789654123 output xml
20:37 adam789654123 i would never write xml
20:37 adam789654123 i would write a program that writes my xml
20:37 adam789654123 or find one if your into that kind of thing
20:37 adam789654123 ;)
20:37 GuShH_ for what I'm doing there are no free tools
20:37 GuShH_ and I'm not into paying for non physical tools
20:37 adam789654123 so youtput xml via embedded lists
20:38 GuShH_ I could simplify and hard-code everything....
20:38 GuShH_ Only 5 objects, 10 at most.
20:38 adam789654123 (name a b c d) outputs something like <name> a b c d </name>
20:38 GuShH_ Who cares about pretty, these devices are not exactly desktop PCs
20:38 adam789654123 im not sure the exact format, but thats the idea
20:39 adam789654123 maybe something like
20:39 adam789654123 (object (name value) (name value) (name value))
20:39 adam789654123 as
20:40 adam789654123 <object> name value, name value, ...
20:40 GuShH_ imagine an actual tree branch with smaller branches (n amount) and their respective leaves
20:40 adam789654123 ok
20:40 adam789654123 can you output in a format that you can read in?
20:40 adam789654123 that would be ideal
20:41 GuShH_ each leaf would have an offset from the origin, so we're talking a simple matrix system
20:41 GuShH_ Hrmmm sure but there are restrictions
20:41 adam789654123 so then to set up the enviroment, you simply have to read in the file
20:41 GuShH_ I can serialize...
20:41 adam789654123 ok
20:41 adam789654123 so there you go i guess
20:41 GuShH_ But I need this for content creatio
20:41 GuShH_ creation
20:41 ShH_ idly scratches MrCurious'
20:42 adam789654123 if you output via json and read via json, that should be fine, no?
20:42 GuShH_ yes but what is converting the visual input into the initial json, I don't want to spend hours writing tools
20:42 adam789654123 "JSON (/ˈdʒeɪsɒn/ JAY-soun, /ˈdʒeɪsən/ JAY-son), or JavaScript Object Notation, is an open standard format that uses human-readable text to transmit data objects consisting of attribute–value pairs. It is used primarily to transmit data between a server and web application, as an alternative to XML."
20:42 adam789654123 haha
20:42 adam789654123 thats exactly what i said
20:43 MrCurious see a pesso, pick it up. congratulations, your now a street cleaner
20:43 GuShH_ yes all AJAX crap uses it, just about all of it.
20:43 GuShH_ MrCurious: it's Peso
20:43 adam789654123 so its basically just lists with each object and its values
20:44 adam789654123 "Because most JSON-formatted text is also syntactically legal JavaScript code, an easy way for a JavaScript program to parse JSON-formatted data is to use the built-in JavaScript eval() function, which was designed to evaluate JavaScript expressions. "
20:44 adam789654123 see "JavaScript eval()" at https://en.wikipedia.org/wiki/JSON
20:45 GuShH_ that's an easy way to open even more security holes
20:45 MrCurious gush, what can 1 Peso buy?
20:45 GuShH_ not much anymore, it used to be equal to 1 USD
20:45 GuShH_ and in one point, slightly better.
20:45 adam789654123 well, if your want some fun you might be able to sandbox the eval
20:45 MrCurious wow. thats really bad... as US dollars used to be worth more
20:46 GuShH_ you don't say
20:46 MrCurious shame you cant get it in rolls about 4" across for household use...
20:46 adam789654123 basically have your own eval that will only pass certain things to eval
20:46 ShH_ won't en
20:46 adam789654123 like `gush's_object_eval'
20:47 adam789654123 which will only do function calls that you are planning on
20:47 GuShH_ adam789654123: I'm trying to avoid Java (native to whatever I write for Android at this point) I can use json though, js only for html5 targets
20:47 adam789654123 you can whitelist certain functions
20:47 adam789654123 javascript or java?
20:48 GuShH_ Java for android.
20:48 adam789654123 ok
20:48 GuShH_ JavaScript for HTML5
20:48 adam789654123 because im reading that json is java script object notation
20:48 GuShH_ That's why I'm trying out Monkey-X to avoid dealing with Java directly.
20:48 GuShH_ Yes but either can handle JSON
20:48 adam789654123 ok
20:48 GuShH_ and you can parse json anywhere....
20:48 adam789654123 well avoid Java if you can
20:48 adam789654123 Javascript seems great though
20:49 adam789654123 JSON seems fine, but you may have to figure how to implement it the way you want
20:49 GuShH_ MrCurious: I'm depressed enough with the current situation, there's no need for your assistance on that matter...
20:50 MrCurious understood. things will get better.... we managed to survive the Bush years, and the devistation left in teh aftermath...
20:51 GuShH_ Don't think so
20:51 GuShH_ Nobody ever set an example here, over there they have.
20:52 MrCurious cant you sneak into a better country like peru or brazil?
20:52 GuShH_ legally you can't exit with more than X amount of cash on you
20:52 GuShH_ it's like Cuba, they don't want you to think for yourself.
20:52 MrCurious money-moving-drones
20:53 i-make-robots mules!
20:53 GuShH_ girlfriend!
20:53 i-make-robots that's what I sa-aaah, you almost got me there.
20:53 GuShH_ we are assuming physical money, could be digital as well
20:53 GuShH_ which I guess would make it even harder.
20:54 MrCurious you could convert you peso to Bit-Con
20:54 GuShH_ seeing as they even blocked paypal transactions between local accounts
20:54 GuShH_ whaaaaaaaahahaaa
20:54 GuShH_ MrCurious: I would need millions for one bitcoin!
20:54 i-make-robots Doge Coin is gaining value faster.
20:54 MrCurious not bitcoin... bitcon
20:54 MrCurious its a scheme that will collapse
20:54 GuShH_ I'm not paying attention
20:54 GuShH_ don't care for toy currencies
21:03 i-make-robots I don't think they have a LEGOcoin yet
21:04 i-make-robots but if they had a MarioCoin I'd be all over that. mostly under it, jumping up, with one fist raised.
21:15 adam789654123 internet currencies are very interesting to me
21:15 adam789654123 im curious where they will be in 10 years time
21:15 GuShH_ lol
21:16 adam789654123 their value depends on their ability to act as a store of value
21:16 adam789654123 the longer they can hold their value, the more that people will invest into them
21:22 robotustra_ I can tell you joke
21:22 robotustra_ "asimo blueprint"
21:23 robotustra_ sounds for me like "pregnant man"
21:23 GuShH_ robotustra: you need to be at least THIS NERD to get it
21:23 adam789654123 honda's robot?
21:23 GuShH_ robotustra: is your alien head fully operational now?
21:23 am789654123 scratches his
21:23 robotustra_ is asimo blueprint will be available for geeks?
21:24 GuShH_ what
21:24 robotustra_ no
21:24 robotustra_ not yet
21:24 robotustra_ I just did version 3 of inner frame to mount eyes
21:24 GuShH_ robotustra: black people are 2 stroke, who knew http://imagizer.imageshack.us/v2/800x600q90/811/cify.jpg
21:24 robotustra_ thes weekend I'll mill some parts for it
21:24 adam789654123 hmm.... i think im gonna make a robocop arm
21:25 GuShH_ adam789654123: make sure it holds a gun with infinite ammo
21:25 adam789654123 just dont shake its hand
21:25 adam789654123 500 foot pounds of pressure and all, you know
21:25 GuShH_ there might be a niche market for robocop hand fetish freaks
21:25 adam789654123 ouch
21:25 robotustra_ may be you'll just built amo in the arm?
21:25 robotustra_ ammo
21:26 GuShH_ in the movies he seems to shoot 1000s of rounds, never reloading
21:26 robotustra_ built in gun
21:26 adam789654123 that because of his gun
21:26 adam789654123 that shit is completely realistic
21:26 adam789654123 what are you trying to say/
21:26 adam789654123 ?
21:26 GuShH_ LOL
21:26 GuShH_ "because of his gun"
21:26 GuShH_ explain?
21:27 adam789654123 i dont have to
21:27 GuShH_ the part with the brain in the tank is still scary to me
21:27 adam789654123 just watch the movie and you can see it
21:27 GuShH_ you should, otherwise you end up looking like one of those religious tools
21:27 adam789654123 how about the self destructed robots on robocop 2 or 3
21:27 adam789654123 think it might have been 2
21:28 adam789654123 one imediatly shoots itself in the head
21:28 ShH_ is not good with movie num
21:28 adam789654123 i have problems counting too
21:28 adam789654123 :)
21:28 GuShH_ that sounds like one of robotustra's robots
21:28 adam789654123 naked gun 32 and a third or something
21:28 adam789654123 thats a bit tricky
21:28 robotustra_ GuShH_: version 2 of the inner frames http://postimg.org/image/5g0o1y2gd/full/
21:28 GuShH_ lol
21:28 GuShH_ the entire naked gun series is fantastic
21:29 robotustra_ with bigger compartments for PCBs
21:29 GuShH_ robotustra: still using the russian pride cad?
21:29 adam789654123 "Scarlet had no idea her skirt was actually ----"
21:29 adam789654123 im gonna make a madlibs
21:30 robotustra_ I don't use hipster software like SW
21:30 GuShH_ you use the equivalent russian hipster software
21:30 adam789654123 i like when hes the famous singer at the ball game
21:30 adam789654123 haha
21:30 robotustra_ russian soft is not hipster by definitions
21:30 robotustra_ russian soft is not hipster by definition
21:30 adam789654123 he takes his umpire mask off, and everyone recognizes him as the singe
21:30 GuShH_ it's commie ?
21:31 robotustra_ socialistic
21:31 adam789654123 or when he talks to the queen and forgets to turn off the mic when he goes to the bathroom
21:32 adam789654123 i did some renovation at a place that recorded their own tv shows, and in the bathroom had a sign, "dont forget to turn off your mic"
21:32 robotustra_ socialistic is because you can take a student version for FREE
21:33 robotustra_ but no americans use them because of lack of intelligence
21:33 ShH_ hands adam789654123 the glock and points at robotu
21:34 adam789654123 well... he must be correct.... i have no idea about socialist russian hipster software
21:34 adam789654123 must be a niche thing
21:35 adam789654123 hmmm
21:35 adam789654123 well... he must be correct.... i have no idea about socialist russian software
21:35 adam789654123 "russian soft is not hipster by definition"
21:35 GuShH_ adam789654123: no, he said all americans lack the intelligence to use russian software
21:35 am789654123 doesnt pay attention well en
21:36 adam789654123 well hes correct
21:36 adam789654123 if we were that smart we would be able to speak russian
21:36 GuShH_ I don't think you care that's the point
21:36 GuShH_ do you study languages in school?
21:36 adam789654123 no
21:36 adam789654123 a little spanish
21:36 adam789654123 2.5 years
21:36 GuShH_ we studied English... but we also had French
21:36 adam789654123 but kindof a joke
21:37 GuShH_ Then again I didn't care for French.
21:37 adam789654123 me neither about spanish
21:37 adam789654123 im more interested now though
21:37 GuShH_ Why?
21:37 adam789654123 why are my interested?
21:37 GuShH_ So you may hire wetbacks at a lower price?
21:39 GuShH_ Are you going to mill us to death?
21:39 adam789654123 spell check and gramar check are for people with no b*lls
21:40 GuShH_ I don't have spellcheck here
21:40 adam789654123 i like to display my lack of intelligence
21:40 GuShH_ It's just a dumb IRC client
21:40 adam789654123 i love it when i can get you roped in, thinking im dumb and then.....
21:40 adam789654123 wammo
21:40 adam789654123 whammo
21:40 GuShH_ failo.
21:40 adam789654123 i prove im even dumber then that
21:41 adam789654123 dummer
21:41 adam789654123 dumber
21:41 adam789654123 hmmm
21:41 GuShH_ dumb and dumber!
21:41 GuShH_ funny movie, the first one that is.
21:41 GuShH_ that second one was a complete failure.
21:41 adam789654123 yeah
21:41 adam789654123 i had to look it up
21:41 adam789654123 yea
21:41 adam789654123 i just heard another is comming out
21:41 GuShH_ come on...
21:42 adam789654123 yeah
21:42 GuShH_ Are you serious?
21:42 adam789654123 with Jim Carrey and all
21:42 adam789654123 2 was terrible
21:42 GuShH_ It's been 20 years
21:42 adam789654123 i thought, what did i just watch
21:42 -card.freenode.net:#robotics- [freenode-info] channel flooding and no channel staff around to help? Please check with freenode support: http://freenode.net/faq.shtml#gettinghelp
21:46 robotustra_ I just have my experience
21:46 robotustra_ I spend 20 minutes to start draw in solid Wirks
21:46 robotustra_ works
21:46 robotustra_ and 1 day to start to draw in T-Flex
21:47 robotustra_ but after I compared the speed of work of both products
21:47 robotustra_ solid works is a monster of cads
21:48 robotustra_ T-Flex fly in virtual machine
21:48 adam789654123 our education system sucks, so im not suprised by your experience
21:48 robotustra_ I'm not sire that Solid works will even start in VM
21:48 robotustra_ sorry, I'm almost PhD
21:48 adam789654123 watch our commercials and you will get an idea of our culture
21:48 robotustra_ and I studied all my life
21:49 robotustra_ I have a good idea about usa life because I live here already 3 years
21:49 adam789654123 studied for what?
21:49 robotustra_ physics
21:49 adam789654123 i hope youve done something too
21:49 adam789654123 oh
21:50 adam789654123 can you tell me something you think is cool about what you study
21:50 GuShH_ he likes it when shit hits the fan
21:50 adam789654123 im interested in MITs book on Classical Mechanics
21:50 adam789654123 have you ever seen that?
21:50 robotustra_ GuShH_: tell for yourself
21:50 GuShH_ parsing error
21:50 GuShH_ robotustra: time to study English!
21:51 ShH_ g
21:51 adam789654123 http://mitpress.mit.edu/sites/default/files/titles/content/sicm/book.html
21:51 GuShH_ robotustra: so you are remaking most of the head??
21:51 robotustra_ GuShH_: too late, I already had my IELTS test
21:51 GuShH_ and failed miserably I hope.
21:51 adam789654123 maybe you can understand this stuff
21:52 robotustra_ I hope I get enough to apply for canadian citizenship
21:52 GuShH_ how the hell do they achieve -80dB in those shitty iso booths they build everywhere
21:52 GuShH_ they're single walled insulated with some padding inside
21:53 adam789654123 so you like pysics, or are you glad to be done studying so you can collect a paycheck for your degree?
21:53 robotustra_ ok, it's usual theoretical mechanics
21:53 GuShH_ I'm at 38dB average where I code most of the time
21:53 adam789654123 yeah
21:53 robotustra_ 1st year of university
21:53 adam789654123 interesting to me
21:54 adam789654123 the physics i guess up to about the beginning of the 19th century
21:54 adam789654123 uh
21:54 robotustra_ no
21:54 adam789654123 17th century
21:54 adam789654123 my mistake
21:54 adam789654123 18th century
21:54 robotustra_ physics has started more than 2000 years ago
21:54 adam789654123 not sure
21:55 adam789654123 i know there where medieval scientists
21:55 adam789654123 and i know some about the ancient Greeks
21:55 robotustra_ and if to beleive that pyramides were built more that 10000 years ago
21:55 adam789654123 ok
21:55 adam789654123 i thought about 4000
21:55 robotustra_ it means that physics is very old science
21:55 adam789654123 but whatever
21:56 GuShH_ they knew about cantilevers and basic friction for sure
21:56 robotustra_ 10500
21:56 adam789654123 physics is about what, 10 billion years old
21:56 adam789654123 give or take
21:56 adam789654123 :)
21:56 robotustra_ if to tell about modern physics - 2000 years about
21:56 adam789654123 im interested in mechanics
21:56 robotustra_ greeks, they invented "proof"
21:56 adam789654123 the study of motion
21:57 GuShH_ robotustra: what about the easter island
21:57 robotustra_ this book is too complicated for begginers
21:57 GuShH_ the way they would move the moai
21:57 adam789654123 who cares if its too complicated
21:57 GuShH_ adam789654123: he does have some issues
21:57 adam789654123 it looks awsome
21:57 adam789654123 thats enough for me
21:57 robotustra_ do you know what is integral?
21:58 robotustra_ of derivative?
21:58 adam789654123 a little bit
21:58 adam789654123 id have to look it up again
21:58 adam789654123 but thats math anyway
21:58 adam789654123 so i can learn math indepentand
21:58 robotustra_ so, how are you going to reed this book?
21:58 adam789654123 i can program
21:58 GuShH_ does it have pretty pictures?
21:58 adam789654123 i can learn math
21:58 robotustra_ no, you can't
21:58 adam789654123 i cant learn math?
21:58 GuShH_ robotustra: why so negative?
21:59 adam789654123 because im american
21:59 adam789654123 :)
21:59 GuShH_ adam789654123: no you have to pay 4+ years of university otherwise "you can't" that's what they think.
21:59 robotustra_ you can't read particulaly this MIT book without math cources
21:59 adam789654123 i think ill be able to do it
21:59 robotustra_ you don't understand the meaning of math equations
21:59 adam789654123 just need to get a good grasp of calculus
21:59 adam789654123 and im already on my way
21:59 adam789654123 im studying algebra now
22:00 adam789654123 just wrote a framework for polynomial arithmetic
22:00 robotustra_ algebra is not enough
22:00 adam789654123 i know that
22:00 robotustra_ what about differental equations?
22:00 adam789654123 thats why i said i need a good grasp of calculus
22:00 adam789654123 what i dont know, i can learn
22:00 robotustra_ what about math analisys?
22:00 adam789654123 what good are they without a good grasp of polynomials?
22:01 robotustra_ what about analytical geometry?
22:01 adam789654123 or a good grasp of polynomials without a grasp of basic number theory?
22:01 adam789654123 it all builds up
22:01 adam789654123 im making a foundation for the study of calculus
22:01 robotustra_ where are you at now?
22:01 adam789654123 i dont need to dive in
22:01 adam789654123 i just told you about the polynomial arithmetic framework
22:02 adam789654123 ill show you a book that looks good
22:04 robotustra_ do you know what is lagrangian?
22:05 adam789654123 who cares if i dont know it
22:05 adam789654123 i can learn what i dont know
22:05 robotustra_ how old are you?
22:06 robotustra_ can you lick away iceberg?
22:06 robotustra_ theoretically you can
22:07 adam789654123 34
22:07 robotustra_ put practically - who knows
22:07 robotustra_ you'll never learn physics
22:07 robotustra_ too late
22:07 adam789654123 hahaha
22:07 GuShH_ robotustra: dipshit
22:07 robotustra_ I'd started when I was 7 y.o
22:08 robotustra_ now I'm almost 40
22:08 adam789654123 and thats what you think i would have to do
22:08 adam789654123 based on your experience
22:08 adam789654123 but your not me
22:08 adam789654123 :)
22:08 robotustra_ and you are not me
22:08 adam789654123 besides, im not trying to be a physisist
22:08 adam789654123 i just like physics
22:08 robotustra_ I passed theoretical mechanics when I was 19
22:09 adam789654123 People can do more then one thing you know
22:09 robotustra_ and want to make a robot ARM?
22:09 adam789654123 people can learn new things too
22:09 adam789654123 it was a joke
22:10 robotustra_ so, what are you planing to do?
22:10 GuShH_ ok using the raw accelerometer won't cut it... time to bust out the vec3 lib
22:10 robotustra_ ok,
22:10 GuShH_ robotustra: quit crushing his hopes and dreams!
22:10 robotustra_ one good game tell me that I shouldn't mock noobs
22:10 adam789654123 if hes crashing my hopes and dreams so be it
22:10 GuShH_ you are only too old to do something when you can't breathe anymore
22:10 adam789654123 that was a poor attempt at it though
22:10 adam789654123 ;)
22:10 adam789654123 im gonna keep doin stuff as long as i live
22:11 adam789654123 will i accomplish it all, no
22:11 adam789654123 but whatever
22:11 robotustra_ good
22:11 adam789654123 im alive and kicken, so im gonna use that
22:11 robotustra_ I would like to be 34 years old than 40 years old
22:11 adam789654123 im just a very curious person
22:11 adam789654123 so im gonna be learning about this
22:11 adam789654123 might be learning about it for the next 40 years
22:11 adam789654123 who knows
22:11 adam789654123 but im interested
22:11 robotustra_ we all here very curious
22:12 adam789654123 im not in a rush either
22:12 robotustra_ we are
22:12 robotustra_ I noticed this
22:12 adam789654123 i dont want to spoil the experience of learning it
22:12 robotustra_ you already did it
22:12 adam789654123 why should i be in a rush
22:13 adam789654123 i have lots of other stuff i want to do also
22:13 robotustra_ becaue it's TOO late for study
22:13 adam789654123 im studying, so you must be wrong
22:13 robotustra_ 34 is a half of life already
22:13 adam789654123 your statement is illogical
22:13 adam789654123 ive just started
22:13 adam789654123 studying this
22:13 robotustra_ by yourself or in the uni?
22:14 adam789654123 im already got my eye on a quality text from mit, and im plotting out my mathematical education
22:14 adam789654123 by myself with the help of text books for now
22:14 robotustra_ don't waste the time on this book
22:14 adam789654123 why?
22:14 robotustra_ it's misleading
22:14 adam789654123 explain
22:14 robotustra_ you'll not do any practical things
22:14 adam789654123 it strictly computation
22:15 adam789654123 but im also interested in computation
22:15 adam789654123 so its cool
22:15 adam789654123 i would also like to do "real physics"
22:15 robotustra_ this book is to learn how to investigate complex mechanical systems
22:15 adam789654123 but i need good ideas for some experiments to do
22:15 adam789654123 right
22:15 adam789654123 that is something im interested in
22:15 adam789654123 the computational mechanics
22:16 robotustra_ I would propose you to formulate TASK for yourself and after aquire knowledge to solve it
22:16 robotustra_ I'm pro in computational mechanics
22:16 adam789654123 thats exactly what i sais im doing
22:16 armyofevilrobots robotustra; don't hammer on people that want to learn. We're not in here to compete with each other, we're in here to learn things and get advice.
22:16 robotustra_ what do you know about numerical equations?
22:17 adam789654123 i thought the book was cool, i think computational mechanics is cool, and im upping my math skills
22:17 ShH_ hifives armyofevilro
22:17 adam789654123 that they have numbers
22:17 robotustra_ armyofevilrobots: are you a personal advocate of adam789654123?
22:17 adam789654123 i like being grilled
22:17 adam789654123 i can take it
22:17 adam789654123 but i have to do something
22:17 robotustra_ adam789654123: start from simpler book
22:18 adam789654123 be back in about 5
22:18 robotustra_ it's my advice
22:18 adam789654123 i might do a simpler book before that one
22:18 adam789654123 but that does not ruin my plans
22:18 adam789654123 :)
22:18 adam789654123 bb in a few
22:18 robotustra_ http://www.feynmanlectures.caltech.edu/
22:19 armyofevilrobots I'll admit that book is a bit math heavy to start with.
22:19 robotustra_ which one?
22:19 robotustra_ MIT?
22:19 armyofevilrobots the SICM. Yeah.
22:20 armyofevilrobots Funny, I hadn't seen it before. I expected it to be simple based on SICP being such a bottom up book.
22:20 robotustra_ I didn't apply theoretical mechanics approach in my live
22:20 armyofevilrobots I guess they have higher expectations of engineering/mathematics students.
22:21 robotustra_ no, they just putting shit in their brain
22:21 armyofevilrobots Lagrangians and state space stuff is pretty cool, but yeah, 99.9% of everything I have ever done was easily handled with a bit of manual PID tuning, including a balancer bot.
22:22 robotustra_ when we go to practice - we have to solve diff equations numerically
22:22 GuShH_ otherwise they make him wear a donkey hat
22:22 robotustra_ and write out all forces not count energy
22:23 robotustra_ feinman gives some useful approaches to solve static and dynamic tasks using energy conservation law
22:26 armyofevilrobots Man, I love the sound of a CNC working in the other room. It's like having your own army of elves to do your bidding.
22:26 myofevilrobots not trying to highjack, just sa
22:26 GuShH_ lol
22:27 armyofevilrobots It just shifted to fast back and forth high-low frequency hums, so it's doing the scalloping in the smaller holes now. Nearly done :D
22:27 robotustra_ armyofevilrobots: show me you cnc
22:28 MrCurious welcome to #CNCporn
22:28 adam789654123 the feynman lectures look good too actually
22:28 adam789654123 maybe that would be a better starting point
22:29 GuShH_ MrCurious: isn't that #linuxcnc?
22:29 MrCurious do they swap pictures of CNC machines using the tor network there?
22:29 GuShH_ maybe
22:30 robotustra_ cnc is also a robot
22:32 adam789654123 im rethinking that robocop arm project again
22:32 adam789654123 this one give the middle finger
22:33 GuShH_ watched The Fly in 1080p yesterday... it's still pretty good after all these years
22:33 adam789654123 funny how high def makes older movies look like home movies.
22:33 GuShH_ not home movies from that era though
22:33 armyofevilrobots One sec.
22:34 adam789654123 yeah
22:34 adam789654123 what are my waiting for?
22:34 adam789654123 hurry up
22:34 GuShH_ huh
22:34 adam789654123 whatever it is im waiting for, i dont want to waint anymore
22:34 adam789654123 oh
22:34 adam789654123 uh, armyofevilrobots "One sec."
22:35 GuShH_ he was brutally murdered by the cnc
22:35 adam789654123 or was it an army of elves protecting their workers rights?
22:35 armyofevilrobots Just waiting for dropbox upload.
22:36 GuShH_ " no more humming! no more humming! "
22:36 GuShH_ "more ham or no hum! more ham or no hum!"
22:36 adam789654123 "we shall not be replaced by a cnc"
22:36 robotustra_ http://www.youtube.com/watch?v=zsoj4di37iQ
22:36 adam789654123 "you want anything done in this town, hire the army of elves"
22:37 robotustra_ I like this exosceleton
22:37 adam789654123 robotustra: is that a picture of you?
22:37 adam789654123 is that your youtube channel?
22:38 GuShH_ all russians look alike
22:38 GuShH_ drunk and crazy

22:38 adam789654123 i designed that ship
22:38 adam789654123 when i was 7 years old
22:39 armyofevilrobots hahaha.
22:39 adam789654123 that is some f*ing crazy animation
22:39 armyofevilrobots So, a bit longer than a sec. My camera auto-upload wasn't working right.
22:41 robotustra_ armyofevilrobots: big one, do you mill wood only?
22:41 armyofevilrobots That's just the big cnc. I have a smaller one for metal.
22:42 robotustra_ ok
22:42 armyofevilrobots but that big one does brass and plastic just fine too.
22:42 armyofevilrobots and aluminium.
22:42 adam789654123 cool cnc
22:42 robotustra_ this is mine http://www.youtube.com/watch?v=mLQJuMPiDeA
22:43 robotustra_ http://maholet.livejournal.com/30530.html
22:44 adam789654123 nice
22:45 armyofevilrobots Yeah. My little machine is about the same size, but you have a WAY nicer spindle.
22:45 armyofevilrobots Is that a chinese VFD?
22:45 robotustra_ yes
22:45 robotustra_ 1.5kW
22:45 GuShH_ measure your dicks somewhere else!
22:45 armyofevilrobots How do you like it?
22:45 robotustra_ GuShH_: :)
22:45 adam789654123 my spindle is bigger then yours
22:45 armyofevilrobots THUD.
22:45 GuShH_ most VFDs are taiwan, china...
22:45 robotustra_ it's ok, I already ise it for 1 year
22:46 robotustra_ use
22:46 robotustra_ it's fine
22:46 GuShH_ simple to program?
22:46 armyofevilrobots cool. Maybe next year I'll get one :)
22:46 armyofevilrobots this year I am too poor.
22:46 robotustra_ I don't program it
22:46 adam789654123 cnc is way beyond what i would dive into at this point
22:46 armyofevilrobots It's just a pulse-train isn't it?
22:46 robotustra_ I just turn it on of off manually
22:46 adam789654123 but i like it
22:47 armyofevilrobots adam789654123: CNC isn't that hard. It's actually a good way to learn about the controls in most things.
22:47 adam789654123 wonder how hard it wold be to make one from scratch
22:47 armyofevilrobots not hard.
22:47 robotustra_ 4-6 months
22:47 armyofevilrobots Well, depends what you mean by "from scratch".
22:47 adam789654123 motors over a grid somehow
22:47 robotustra_ I did mine almost from scratch
22:47 adam789654123 not sure how it might work
22:48 armyofevilrobots if you go buy good step drivers and use linuxEMC or Mach3, then it's a lot easier.
22:48 adam789654123 ok
22:48 armyofevilrobots But if you wanna get really close to the metal, building a reprap is a great way to get your feet wet without blowing too much $
22:48 adam789654123 thats the thing
22:48 robotustra_ http://maholet.livejournal.com/?skip=20&tag=cnc
22:49 adam789654123 its not practical for me to buy an expensive machine
22:49 GuShH_ it is for me if you're paying
22:49 adam789654123 hmmm
22:49 armyofevilrobots Here's my machine printing new parts for itself. I think I built the base for about $400, and then just kept upgrading it with new parts I made myself.
22:49 armyofevilrobots https://www.youtube.com/watch?v=Q5YwP2fZyKY
22:50 armyofevilrobots and that was pretty close to "from scratch".
22:50 robotustra_ I did mine on a kitchen table
22:50 robotustra_ with a rusty file tool
22:51 armyofevilrobots both ways uphill in the snow :D
22:51 GuShH_ just a file eh...
22:51 adam789654123 wonder what parts its printing though
22:51 robotustra_ :)
22:51 adam789654123 i mean, i know its not printing all that stuff
22:52 adam789654123 3d printers look interesting, but its something that i cant think of a use that justifies the complexity at this time
22:52 adam789654123 so i just dont think about the much
22:52 GuShH_ complexity or the cost and time
22:52 armyofevilrobots It's surprising how useful it is.
22:52 adam789654123 ok
22:53 robotustra_ nice setup https://www.youtube.com/watch?v=oIipkRWnMH4
22:53 GuShH_ armyofevilrobots: give us examples! a list of at least 10 items
22:53 armyofevilrobots I make parts all the time on it, and I make a lot of pieces for other automation stuff.
22:53 GuShH_ you need to wrap your mind around it first
22:53 adam789654123 what kind of parts?
22:53 GuShH_ otherwise you may not be using it enough
22:53 adam789654123 it prints platic parts right?
22:54 adam789654123 so maybe, like, little platic gears, for example
22:54 GuShH_ yes ABS or PLA mainly
22:54 GuShH_ depends....
22:54 GuShH_ I'd like to try nylon
22:54 armyofevilrobots cases for raspberrypi (the canonical example), all the parts on the 3d printer, lost pla casting positives, many electronic spacers/standoffs, various cnc part enclosures, molds for casting elastomers and epoxy, characters in 3d for my wife to mold/sculpt.
22:54 robotustra_ I mill aluminium
22:54 adam789654123 that you designed using cad or something
22:54 robotustra_ and brass
22:54 armyofevilrobots mine does nylon, it's amazingly tough.
22:54 robotustra_ easily
22:54 GuShH_ robotustra: you mill ass.
22:54 robotustra_ :)
22:54 GuShH_ armyofevilrobots: the same nylon used on whipper snippers
22:54 adam789654123 print in brass?
22:54 adam789654123 never mind
22:54 adam789654123 im reading bottom to top
22:54 armyofevilrobots NO, not the weedwhacker stuff. It has glass in it Destroys your printer.
22:55 adam789654123 stupid americans
22:55 armyofevilrobots Use taulman filament.
22:55 GuShH_ armyofevilrobots: it does? not all are the same
22:55 GuShH_ I'm talking Grilon but that's a brand
22:55 armyofevilrobots I haven't tried, but one of the guys in my local club did, and it clogged his print head.
22:55 adam789654123 i think it might be interesting to come up with a mechanical concept, and print it out
22:55 GuShH_ and what would it destroy exactly
22:55 GuShH_ ok...
22:55 GuShH_ I make them so who cares.
22:55 adam789654123 as say, a prototype
22:55 armyofevilrobots and the wrong stuff can gas off pretty low temp, which is bad.
22:55 adam789654123 that would be neat
22:56 armyofevilrobots taulman has a way lower melting temp than other nylons, and the risk of fluctuating into the range where you offgas cyanide is way less.
22:56 GuShH_ abs gasses off just as well
22:56 GuShH_ of course different compounds
22:56 adam789654123 its one of those things that looks interesting to me, but looks very complicated
22:57 adam789654123 and i like very simple
22:57 armyofevilrobots ABS is pretty low, but yeah, I don't like it. PLA is way less nasty, but even it can burn if you're not careful.
22:57 GuShH_ can you print accurate high diameter medium to high pitch threads?
22:57 adam789654123 so i would have to be very motivated to work on something like that
22:57 armyofevilrobots @GuShH_ No., or at least, I never try. I always just print undersize and thread the hole.
22:57 armyofevilrobots That works pretty good.
22:57 adam789654123 but more my speed right now might be some of the older metal wolking equipment
22:57 GuShH_ for instance a 2 or 2.5 inch coupling
22:57 adam789654123 like lathes and stuff
22:57 armyofevilrobots but inserts or captive nuts are the best.
22:58 GuShH_ armyofevilrobots: not thinking assembly, just a water fitting
22:58 armyofevilrobots printed threads are really tricky, it's basically a stunt if you try it.
22:58 GuShH_ that's why I ask :P
22:58 armyofevilrobots maybe in nylon, it's really flexy and forgiving, but even abs is probably tricky.
22:58 armyofevilrobots I would print oversize threads and chase them at most.
22:58 GuShH_ I could cut them on the lathe though, just wondering.
22:58 armyofevilrobots because of aliasing due to the layers.
22:59 armyofevilrobots That's a tool I need in house.
22:59 armyofevilrobots a lathe.
22:59 GuShH_ if I had a cnc milling machine I'd probably try that
22:59 armyofevilrobots Hmmm, quiet cnc is quiet. brb.
22:59 GuShH_ If I build a cnc mill it's got to be big enough to be useful
23:00 GuShH_ but right now... no actual space for one. unless I design it to be easily taken apart
23:01 adam789654123 im headin off
23:01 adam789654123 good night all
23:02 armyofevilrobots last pass, just scalloping the top surfaces.
