01:26 AM rue_bed: http://www.icstation.com/images/uploads/5378_1%281%29.jpg
01:26 AM rue_bed: thats nice and simple!
01:27 AM gottaname|wurk: rue_bed, how much weight can that take?
01:27 AM rue_bed: ... and REALLY delicate...
01:27 AM gottaname|wurk: ...
01:27 AM rue_bed: It looks like it might be able to carry its own weight
01:27 AM gottaname|wurk: such power to weight ratio
01:28 AM gottaname|wurk: much durability
01:29 AM rue_bed: "WHILE WE RUN, REMIND ME __WHY__ YOU MADE A BORG SHARK!?"
01:31 AM gottaname|wurk: BECAUSE WE CAN
01:31 AM gottaname|wurk: its not about the robot, its about sending a message
01:31 AM mrdata: seemed like a nice idea at the time
01:32 AM rue_bed: "ED209!!!! ED209!!!! ED209!!!!!!! not good with stairs..."
01:32 AM mrdata: i want a bot thats good with stairs
01:33 AM mrdata: how many stairs are there at mar-a-lago
01:33 AM rue_bed: http://garotasnerds.com/wp-content/uploads/2013/02/robocop-droid-prop-1.jpg
01:33 AM gottaname|wurk: mrdata, snake robot
01:33 AM gottaname|wurk: :D
01:33 AM rue_bed: ... thats a pallette off to the left...
01:33 AM jesseg: 18 servo power
01:34 AM gottaname|wurk: jesseg, that's plastic servo power
01:34 AM * gottaname|wurk is still on his way to building a tachikoma
01:34 AM gottaname|wurk: yesssss
01:34 AM rue_bed: https://s-media-cache-ak0.pinimg.com/564x/a0/f3/7c/a0f37c60d9d41eff81b0402e1bbf71b1.jpg
01:35 AM gottaname|wurk: who do you think will win
01:35 AM gottaname|wurk: ED-209 or a tachikoma?
01:35 AM gottaname|wurk: https://www.youtube.com/watch?v=Dwk0PqG0xg0
01:35 AM gottaname|wurk: much cute robot
01:36 AM mrdata: https://www.youtube.com/watch?v=KTlfb-MXCQQ
01:36 AM rue_bed: tachikoma, ed209 is made in usa, which means most of the parts are from china
01:37 AM gottaname|wurk: mrdata, we should build more snake bots
01:37 AM mrdata: hmm
01:38 AM rue_bed: well done snake robot!
05:08 AM multifractal: Some may recall I was asking about ideas for rotated/oriented bounding box prediction for object detection - beyond boxes who align with the edges of the image, tightly inscribing rotated/skewed rectangles etc...
05:09 AM multifractal: Has anyone seen https://arxiv.org/abs/1511.07763 ?
05:12 AM multifractal: Who formulate the vanilla (non-oriented) bounding box prediction as dense classification task, rather than a regression with a very elegant solution...
05:12 AM multifractal: Do you think it could be rejigged to predict oriented boxes?
05:12 AM multifractal: The long and short of their idea is to predict a binary classifier at each ROW and COLUMN of the image - 1/YES if in the bounding box, 0/NO if not in the bounding box. In this sense, a bounding box is characterised by a pair of histograms over the rows and columns of the image.
05:18 AM multifractal: I'd be interested in pursuing a MaxPooling layer that only pools in either the horizontal or vertical direction, resulting in 1D maps that summarize information over rows and cols.
05:22 AM multifractal: Qhoops sorry I thought I was in ##machinelearning :(
05:23 AM Tom_itx: meh, it could apply
05:45 AM Jak_o_Shadows: It sounded like it could apply
07:26 AM veverak: damn it
07:26 AM veverak: I thought I finished
07:27 AM veverak: but one finds out that they made something called Field D*
07:27 AM veverak: astar on steroids
07:27 AM veverak: A. it is D*, so you can chang the graph on the fly and get valid result
07:27 AM veverak: B. it interpolats the result path - perfectly smooth
07:36 AM deshipu: A*roids
07:52 AM * SpeedEvil ponders the channel #machineleaning.
07:56 AM deshipu: I can't sleep I'm holding up the server?
08:43 AM veverak: ok, I think I finally understand D*
08:43 AM veverak: D* lite
01:49 PM anniepoo: first robot - probably delrin
01:51 PM anniepoo: multifractal - usually collision detection is done in stages - only check a more complex collision if the two AABB's collide
02:50 PM Tom_itx: unless it's too late
03:13 PM anniepoo: ??
03:13 PM anniepoo: yes, you have to run the collision detection faster than the motion
03:13 PM anniepoo: that's a pretty well solved problem, since video games require same thing
04:53 PM z64555: collision detection is generally hierarcal, spherical cows, then box cows, then various point-cloud cows
05:15 PM Tom_itx: video games don't have mass or lag from it either
05:44 PM anniepoo: video games simulate mass. You can see that in any race game, etc.
05:45 PM anniepoo: and in fact gazebo pretty much uses the same physics endines I'm familiar with from game dev
06:26 PM anniepoo: https://www.instagram.com/p/BTC08Asjyfi/?taken-by=anneogborn
06:28 PM anniepoo: 8cD final layup of snail shell master. Next step is to apply coating, then plaster mold, then fiberglass inside
06:28 PM anniepoo: 8cD
06:38 PM Snert_: work makes me block instagram.
06:38 PM Snert_: never mind that I'm the guy that does it and knows the way around it.
06:39 PM Snert_: and I'm too lazy to use the bypass.
06:39 PM Snert_: <--- he sucks.
06:40 PM anniepoo: yah, I'm gonna upload it, gimme a minute, I'm helping somebody in ##prolog
06:41 PM solol: how did you find a way around it
06:41 PM Snert_: I just use the bpass login.
06:42 PM Snert_: bypass.
06:42 PM Snert_: or I go in and turn it off.
06:42 PM Snert_: but since it's my job to do what the boss says I don't circumvent things often.
06:43 PM Snert_: I like my paycheck.
07:02 PM anniepoo: 8cD hang on, uploading
07:03 PM anniepoo: .
07:07 PM anniepoo: http://partyserver.rocks/anniepoo/shellLOMpic.jpg
07:08 PM Snert_: huh. just wow.
07:09 PM anniepoo: 8cD
07:09 PM anniepoo: better than being hit with a brick
07:35 PM SpeedEvil: Did you use any guides for that??
07:35 PM SpeedEvil: That's a lot of cardboard
07:54 PM anniepoo: there are three 1/4" holes in each piece (if it's large enough)
07:54 PM anniepoo: I have a jig with same 3 holes, and 2 steel rods
07:55 PM SpeedEvil: ah - to make the curves
07:55 PM anniepoo: I put glue on each piece, and slipped it over the rods
07:55 PM anniepoo: at the ends the pieces are small, so I used two holes near each other
07:56 PM anniepoo: the rods are straight
07:56 PM anniepoo: cardboard cut out with a laser
07:57 PM anniepoo: that's what lines up the layers
07:57 PM anniepoo: horizontally
07:57 PM cnnx: any of you own an APM?
07:58 PM anniepoo: whats an APM?
07:58 PM cnnx: arduino pilot module
07:58 PM cnnx: ardupilot module
07:59 PM jandor: yep
07:59 PM jandor: I think I do
07:59 PM cnnx: jandor: is it easy or hard to setup?
07:59 PM jandor: but its nowhere near me
07:59 PM cnnx: i think its only 30$
08:00 PM jandor: don't know, never tried ) I just used it as one more arduino
08:00 PM cnnx: i want to build a rover with a mission planner console around the APM
08:00 PM cnnx: ok
08:00 PM jandor: I ended up writing my own firmware for that )
08:00 PM cnnx: in C?
08:00 PM malcom2073: APM is pretty easy to set up, but if you're finding it for $30 it's a chinese clone, so expect issues :)
08:00 PM jandor: NIH syndrome at its best
08:00 PM jandor: yes
08:01 PM cnnx: jandor: i love C
08:01 PM jandor: I hate it )
08:01 PM cnnx: i wrote my last control software in it
08:01 PM cnnx: using phidgets
08:01 PM cnnx: to control my linux robot
08:01 PM cnnx: in 2011
08:01 PM jandor: I love python but sometimes I need to write in C
08:01 PM cnnx: malcom2073: you got apm?
08:02 PM cnnx: jandor: so basically you send commands to the serial tty?
08:02 PM jandor: yes
08:02 PM cnnx: or do you write device drivers?
08:02 PM malcom2073: cnnx: Yeah, I used to work with them so I have a few laying around
08:02 PM malcom2073: I actually use them more for motion dataloggers than for autopilots nowadays hehe
08:02 PM cnnx: malcom2073: one guy in #ardupilot goes for rides on youtube live with his apm rover
08:02 PM cnnx: i saw him today
08:02 PM cnnx: its really neat
08:02 PM jandor: one firmware uses mavlink and one couple of others use a text interface
08:03 PM anniepoo: SpeedEvil - should I take some pix of the setup, or do you get it?
08:03 PM malcom2073: Yeah, rover is pretty cool
08:03 PM jandor: btw, thanks for reminding me of ardupilot
08:03 PM cnnx: a lot of people on youtube show how they buy 1/8 scale cars and transform them
08:03 PM cnnx: with apm
08:03 PM SpeedEvil: anniepoo: Oh - LASER cut - I thought you were meaning an eliptical cutting jig with the rods
08:03 PM jandor: I have to take it back
08:03 PM cnnx: np
08:03 PM SpeedEvil: anniepoo: LASER cut is easy
08:03 PM malcom2073: I was thinking of doing a lawn mower with apm
08:03 PM anniepoo: yes, I own a laser
08:04 PM anniepoo: several of them, actually... 8cD
08:04 PM SpeedEvil: I need to mail some people who sell kids 'ATV's on ebay to see if any of them have robotically suitable bits
08:04 PM SpeedEvil: as broken returns they can't do anything with
08:05 PM cnnx: good price you think?
08:05 PM SpeedEvil: who knows.
08:05 PM cnnx: yeah
08:05 PM cnnx: worth a shot
08:05 PM SpeedEvil: http://www.ebay.co.uk/itm/New-800W-Battery-Kids-Quad-ATV-Disc-Brakes-Suspension-Front-Rear-/291960505556 - even whole
08:05 PM anniepoo: kiddy car might work too
08:05 PM SpeedEvil: Is a pretty decent price, when you look at it as a robotics platform
08:05 PM cnnx: today i chatted with a robot droid website .. 1600$usd for a robot platform that carries 75lbs of payload
08:05 PM cnnx: freaking expensive
08:05 PM anniepoo: yes, good idea
08:06 PM cnnx: comes with batteries, motor controls, 4 wd motords, 10" pneumatic wheels
08:06 PM cnnx: frame
08:06 PM malcom2073: I want to build a tracked robot, decent sized
08:06 PM SpeedEvil: http://www.funbikes.co.uk/Black_Electric_Mini_Quad_Fun_Bike_Ride_On_Toy%283627%29.aspx - seems to have some more specs.
08:06 PM anniepoo: I'm building one. I'm learning that tracks are less efficient than wheels, so you end up carrying more battery
08:06 PM cnnx: thats a good price
08:07 PM cnnx: remove all the plastic
08:07 PM cnnx: you're left with the guts
08:07 PM SpeedEvil: 13MPH might actually be lots too fast
08:07 PM cnnx: big tires
08:07 PM cnnx: how many inches
08:07 PM SpeedEvil: So regearing the motor might be nice
08:07 PM anniepoo: SpeedEvil - children grow up
08:07 PM SpeedEvil: anniepoo: mostly.
08:07 PM malcom2073: anniepoo: I was going to do hybrid, or maybe even pure motor drive (differential with clutches maybe)
08:07 PM SpeedEvil: anniepoo: but oddly these don't seem to come up on ebay
08:08 PM anniepoo: advertise for one on craigslist or wherever, bet there's lots of people with one sitting in a garage
08:08 PM SpeedEvil: Craigslist isn't a thing here, and collection is a problem. (no car)
08:08 PM anniepoo: that's why so many robots are built around power chairs
08:08 PM SpeedEvil: yeah
08:09 PM anniepoo: cause people get them, and a few years later, don't need them
08:09 PM SpeedEvil: cnnx: I think 12"
08:10 PM cnnx: SpeedEvil: nice.. so these robot shops on the internet are really jacking up the prices
08:10 PM cnnx: for what they sell
08:10 PM SpeedEvil: cnnx: 'no'.
08:10 PM anniepoo: oh gawd yes
08:10 PM cnnx: although the motor controllers are probably hard to control on a kid toy thing
08:10 PM cnnx: how do you know the commands or interface
08:10 PM SpeedEvil: It's a DC motor
08:10 PM cnnx: yeah but you need an interface
08:10 PM cnnx: to the MC
08:10 PM SpeedEvil: If you can't control that, go home now
08:10 PM SpeedEvil: DC motor control is very easy.
08:11 PM cnnx: i built mine 6 years ago
08:11 PM cnnx: i know how it works
08:11 PM cnnx: but i used motor controllers
08:11 PM anniepoo: cheap electric vehicles like this usually just have on/off control - golf carts often do
08:11 PM SpeedEvil: The 'proper' robot vehicles have numbers of nice things over that.
08:11 PM anniepoo: but yes, one of these would make a good basis for a robot
08:11 PM anniepoo: True
08:11 PM SpeedEvil: Plus, the problem is that the above will be made in 10Ks
08:11 PM SpeedEvil: and the robot will be made in 3s.
08:12 PM anniepoo: I spent $100 on a nice chassis for the snail's base/treads. Happy with it, it was well worth it
08:12 PM SpeedEvil: Plus, of course, the turning radius of those is going to be 2m or so
08:12 PM SpeedEvil: ^diameter
08:12 PM cnnx: anniepoo: show me the link where you bought it pls
08:12 PM SpeedEvil: It's going to be useless even casually indoors.
08:13 PM anniepoo: hang on
08:13 PM cnnx: ok
08:15 PM anniepoo: https://osepp.com/robotic-kits/4-tank-mechanical-kit
08:15 PM anniepoo: looking at kids ATV's on amazon, the price and quality vary enormously
08:15 PM cnnx: looks small
08:15 PM SpeedEvil: anniepoo: yeah
08:15 PM anniepoo: it's 21cm
08:16 PM cnnx: i want something outdoors
08:16 PM cnnx: than can support a 100watt solar panel
08:16 PM cnnx: and deep cycle battery
08:16 PM SpeedEvil: anniepoo: I'm almost contemplating it as a kit of parts, because it's not particularly suitable for what I want it for as is.
08:17 PM anniepoo: I assembled mine stock, but about 25% of it will be replaced in final build
08:18 PM cnnx: https://www.amazon.ca/Rosso-Motors-Wheeler-Electric-Motorcycle/dp/B06XQN61R3/ref=sr_1_39?ie=UTF8&qid=1492562879&sr=8-39&keywords=kid+atv+electric
08:19 PM anniepoo: some of the cheaper ones could be good bases for less capable robots, too
08:19 PM SpeedEvil: http://www.funbikes.co.uk/upload/temp/d2c93089-a9a0-489b-a87f-dcb1f1bb1b75_pad_600x450.jpg - but for example - for any load platform, the front shock could really get in the way, and it might make sense to move the motor back, as well as ripping everything out from the frame up
08:19 PM cnnx: yeah
08:19 PM SpeedEvil: And if I want it to go at 2.5, not 13MPH, the required shocks are very different
08:21 PM cnnx: https://www.amazon.ca/Red-ELECTRIC-ATV-Kids-ATV006/dp/B06XYTX6B8/ref=sr_1_43?ie=UTF8&qid=1492563024&sr=8-43&keywords=kid+atv+electric
08:21 PM cnnx: this takss 110lbs load
08:21 PM cnnx: but its 2000$
08:21 PM cnnx: i mean 1200$
08:21 PM cnnx: not bad
08:21 PM cnnx: cad
08:22 PM SpeedEvil: https://www.amazon.ca/Razor-Ground-Force-Drifter-Kart/dp/B002S143RK/ref=pd_sbs_21_2?_encoding=UTF8&psc=1&refRID=5YWE3X3GD3GP7T18JBF0
08:22 PM SpeedEvil: Might even be better than the above for many things
08:23 PM cnnx: wheels have no grip
08:23 PM SpeedEvil: yes.
08:23 PM SpeedEvil: Often you're wanting a robot for flattish indoor/outdoor type work where that's not a real issue
08:24 PM SpeedEvil: But yes, not one actually designed for no grip
08:25 PM cnnx: SpeedEvil: do you work?
08:25 PM SpeedEvil: I'm medically retired.
08:26 PM cnnx: SpeedEvil: oh due to injury?
08:26 PM SpeedEvil: Disease.
08:26 PM cnnx: was just curious what fields you worked in
08:26 PM cnnx: sorry to hear
08:26 PM SpeedEvil: I got a nasty virus at age 12, and never really recovered.
08:26 PM cnnx: what kind?
08:27 PM cnnx: is this a genuine APM
08:27 PM cnnx: https://www.amazon.ca/APM2-8-Build-Compass-Controller-Multicopter/dp/B01HBFOOCQ/ref=sr_1_1?ie=UTF8&qid=1492563441&sr=8-1&keywords=apm
08:27 PM SpeedEvil: Something trivial. It can lead to post viral fatigue syndrome. If I don't carefully monitor my energy, I can have severe problems. To the point that for example carelessly doing the washing up can mean that the next day cooking a bacon omelette is too hard
08:27 PM SpeedEvil: and confusing
08:27 PM cnnx: ok
08:28 PM SpeedEvil: There are in principle many controllers for around that price
08:28 PM SpeedEvil: or less
08:28 PM cnnx: it says you need c-language
08:28 PM cnnx: i love this thing
08:28 PM SpeedEvil: https://hobbyking.com/en_us/naze32r6-set-pcb-wire-pins.html?___store=en_us
08:28 PM cnnx: c is part of the reason i chose my nick
08:29 PM cnnx: the c in cnnx is for C language
08:29 PM cnnx: the x is for unix
08:29 PM cnnx: nnn are fillers
08:29 PM Plazma: oh snap nice
08:31 PM anniepoo: ok, instead of being unproductive here, I'm going to go do an experimental coating of the snail shell using the one I messed up, just to test technique
08:31 PM SpeedEvil: :)
08:31 PM cnnx: SpeedEvil: i have to take about 10 pills daily
08:31 PM cnnx: or else i end up in the psychiatric ward
08:32 PM SpeedEvil: yeah - no effective treatment for what I've got. They are just now really unraveling what's actually wrong, and perhaps in 2-3 years they'll have a cause, and then it's just another 12-14 for a drug.
08:32 PM SpeedEvil: :/
08:33 PM cnnx: ok
08:36 PM cnnx: wish there was a rover kit that uses the apm
08:36 PM SpeedEvil: why
08:36 PM cnnx: dont wanna break my head re-inventing the wheel
08:36 PM cnnx: so i can put it together
08:36 PM cnnx: and have fun
08:36 PM SpeedEvil: It's just servos
08:36 PM cnnx: ok
08:36 PM cnnx: i like the mission planner interface
08:36 PM anniepoo: cnnx, the OSSEP one just has DC motors
08:37 PM cnnx: ok
08:37 PM anniepoo: ok, I'm going to the shop
08:37 PM cnnx: anniepoo: ok have fun
08:37 PM SpeedEvil: So you just hook motor controllers up to it, standard ones, and if you can't find existing car firmware, just gut 99% of the positioning stuff out of a sta
08:37 PM SpeedEvil: out of the controller
08:38 PM SpeedEvil: Then as far as the software on the other end knows, it's a quad
08:39 PM cnnx: i'm replacing my 15-20 year old computer desk this week
08:39 PM cnnx: i ordered it last week
08:39 PM cnnx: they are delivering this week
08:41 PM cnnx: SpeedEvil: you're in europe if I remember right?
08:41 PM SpeedEvil: scotland
08:42 PM cnnx: canada here, would designing and building hardware/software that would allow us to connect wirelessly interest you?
08:42 PM cnnx: cross continental
08:42 PM SpeedEvil: Unfortunately, I have absolutely no energy for other than a bare handful of things at the moment.
08:42 PM cnnx: ok
08:42 PM cnnx: you seem educated
08:43 PM SpeedEvil: I've tried to keep educated in a variety of fields since dropping out of CS/maths/physics degree
08:43 PM cnnx: ok
08:44 PM cnnx: cubesats really fascinate me
08:44 PM cnnx: but i dont have the money to launch one even if i built one
08:44 PM cnnx: solar energy,linux,sbc,progamming,radio active,etc
08:45 PM cnnx: i guess i could build a stationnary cubesat
08:45 PM cnnx: which i kind of did in the backyard for a number of years
08:45 PM cnnx: a towered powering electronics from solar panels
08:45 PM cnnx: people made me remove it
08:45 PM cnnx: thinking i was weird
08:46 PM Snert: if you're here, you're weird. Welcome.
08:46 PM cnnx: ty
08:52 PM anniepoo: 8cD Gibble Gobble, we accept you!
08:52 PM cnnx: https://www.kickstarter.com/projects/plumgeek/spirit-rover-learn-raspberry-pi-and-arduino-the-fu
08:52 PM cnnx: this is very close to what i want
08:52 PM cnnx: but it doesnt use the APM
08:52 PM cnnx: anniepoo: :)
08:53 PM anniepoo: so, back for 15 minutes while the plaster cloth sets up
08:55 PM rue_house: dozing off in the chainr now
08:55 PM cnnx: rue_house: is it an aeron chair
08:56 PM SpeedEvil: anniepoo: plastering the outside smooth, wax, fibreglass, sand, more fibreglass?
08:56 PM cnnx: i need to find a use for 2 solar panels i have
08:56 PM cnnx: 100 and 85 watts
08:57 PM anniepoo: pretty much
08:58 PM anniepoo: plaster wrap outside, smooth with some additional plaster, wax, plaster mold, fiberglass inside of mold
08:58 PM SpeedEvil: ah
08:58 PM anniepoo: though I'm wondering if I can get away with doing it just over the shell.
08:58 PM SpeedEvil: Way less sanding that way
08:59 PM SpeedEvil: you can also use the excuse that snails don't have perfectly smooth curves
09:00 PM cnnx: SpeedEvil: would it be possible to build a submarine i can deploy in the ocean
09:00 PM cnnx: and it powers by surfacing with solar energy
09:01 PM SpeedEvil: Sure. Sealing is fun, and comms, and power, and sealing.
09:01 PM cnnx: travels at night
09:01 PM anniepoo: Speed, have you fiberglassed before?
09:01 PM SpeedEvil: anniepoo: not decorative stuff.
09:01 PM cnnx: anniepoo: what are you working on?
09:01 PM anniepoo: I'm completely new to it
09:01 PM anniepoo: I'm building a robotic snail
09:01 PM anniepoo: I'm making the shell
09:01 PM cnnx: what size?
09:01 PM cnnx: snails are small
09:01 PM anniepoo: bit over 2 ft
09:02 PM SpeedEvil: anniepoo: ensure adequate ventilation first.
09:02 PM cnnx: ok
09:02 PM SpeedEvil: anniepoo: maybe even supplied air if you're sensitive.
09:02 PM anniepoo: http://partyserver.rocks/anniepoo/snailxray.png
09:02 PM anniepoo: Oh, thanks
09:02 PM SpeedEvil: anniepoo: wear protective glasses when dealing with the catalyst
09:02 PM anniepoo: ok,
09:02 PM cnnx: SpeedEvil: anything that i build and gets deployde im scared that someone will spot it and take/damage it
09:03 PM SpeedEvil: Or eaten by monsters.
09:03 PM anniepoo: I almost lost my sight once, from, of all things, a tiny tube of alpha-cyanoacrylate glue
09:04 PM anniepoo: was the hobbyist kind with the detachable tube
09:04 PM anniepoo: I was in the habit of blowing the tube out, stupidly
09:04 PM SpeedEvil: And even the nicest protective goggles or whatever are only $20 or so
09:04 PM anniepoo: after doing that 500 times, the 501st it flipped a tiny drop in my eye
09:04 PM anniepoo: yes, i have a pair on desk in front of me
09:05 PM anniepoo: when handling chemicals I usually use a full face shield
09:05 PM anniepoo: and/or the chemistry lab type
09:05 PM SpeedEvil: http://www.respirexinternational.com/en/products/air-fed-chemical-garments/air-fed-chemical-suits/simplair-a.e.-suit/ :)
09:06 PM anniepoo: yah, that's probably overkill for a snail
09:06 PM anniepoo: opening the door and doing it on a roller cart near it is probably enough
09:07 PM anniepoo: hmm... this might be easier for mold
09:07 PM SpeedEvil: split into two, and do the inside you mean
09:07 PM * gottaname|wurk wears his ballistic goggles
09:07 PM anniepoo: layer of plaster wrap, followed by plaster shell, backed up with expanding urethane foam
09:07 PM gottaname|wurk: :D
09:07 PM anniepoo: yes, I have to split the mold of course
09:09 PM cnnx: is this a scam? http://premiershipmodels.co.uk/custom-built-models/1193-autonomous-submarine
09:09 PM cnnx: 825$ ??
09:09 PM cnnx: 30 cm
09:09 PM cnnx: is not big
09:10 PM SpeedEvil: 'no'
09:10 PM SpeedEvil: but it's a model, not working
09:10 PM cnnx: oh
09:10 PM cnnx: ok
09:10 PM cnnx: misread
09:10 PM cnnx: says autonomous
09:10 PM cnnx: which is what i searched for in google
09:10 PM anniepoo: yes, split mold is my intention
09:11 PM anniepoo: but it might be simpler just to do all the sanding
09:11 PM SpeedEvil: Papier macher (sp?) can also be useful for working out ideas for fibreglassing
09:12 PM cnnx: im reading that signal travel in deep water is hard
09:12 PM anniepoo: speed, say more
09:12 PM cnnx: with hobby frequencies
09:13 PM SpeedEvil: anniepoo: it's sort of like fibreglass, but non toxic.
09:13 PM anniepoo: I know what it is
09:13 PM SpeedEvil: Draping thicker paper can work much like fibreglass
09:13 PM anniepoo: ah
09:14 PM SpeedEvil: you get teh same issues with crinkling and it not staying fla
09:14 PM SpeedEvil: t
09:14 PM anniepoo: hmm... well, paper mache seems too fragile for shell
09:14 PM anniepoo: but might be strong enough to make the mold
09:14 PM SpeedEvil: I was more meaning to experiment with to get an idea of how it's going to work
09:15 PM anniepoo: I used to have a model railroad
09:15 PM SpeedEvil: Though if you've got plenty of fibreglass it's not an issue
09:15 PM anniepoo: I've used it for that
09:15 PM anniepoo: remember this is for interacting with children -
09:15 PM SpeedEvil: Then a lot of the skills are probably transferrable
09:15 PM anniepoo: Kevlar and vanadium steel would be appropriate 8cD
09:15 PM SpeedEvil: Would you want the shell to be smooth, or shaped like a real snail?
09:15 PM anniepoo: smooth
09:19 PM anniepoo: I'm liking the paper mache idea
09:19 PM anniepoo: not for the shell, but for the mold
09:20 PM SpeedEvil: especially as you don't much care about the exact shape - as long as the edges match, so distortion isn't much of an ussue
09:20 PM anniepoo: well, it makes my life simpler if it's close to the designed size
09:21 PM anniepoo: but the LOM thing introduces some variation anyway
09:21 PM anniepoo: I did think about putting fiberglass over the outside of the 'plug' I made this afternoon
09:21 PM anniepoo: after it's all fiberglassed, soak in water overnight and dig the soggy cardboard out
09:22 PM anniepoo: and pull out the plaster cloth
09:22 PM anniepoo: but that's kind of risky - have to start at zero if it gets messed up
09:31 PM anniepoo: ok, Kevin, my biz partner, turns out has worked with fiberglass a lot
09:31 PM anniepoo: and says just fiberglass over the plug I've got
09:32 PM anniepoo: and slit it down the centerline far enough to bend the edges out and drop plug out
09:32 PM anniepoo: then patch the slit.
09:34 PM anniepoo: 8cD
09:34 PM anniepoo: so, I'm headed back to shop to plaster cloth the mold
09:49 PM rue_house: you know whats important to a system that uses force control?
09:49 PM rue_house: pressure sensing
09:49 PM rue_house: I been thinkiing about pressure sensors latley
09:49 PM rue_house: and it occured to me
09:50 PM rue_house: that not many people use pizos under a oscillator with damping meters for pressure sensing
10:10 PM cnnx: will upgrading from a 2gb 960gtx to 8gb 1070 make a big difference in xplane11 for details and speed?
10:10 PM orlock: maybe
10:10 PM orlock: details will be down to the program
10:11 PM orlock: it should display exactly the same thing, just at higher fps
10:11 PM cnnx: fps means faster movement?
10:11 PM orlock: so is the fps low? are you actually using the hardware GL capabilities?
10:11 PM orlock: if it apepars slow, you may be using software/mesa gl
10:11 PM cnnx: oh
10:11 PM orlock: fps = frames per second
10:11 PM orlock: so mor esmoothness than speed
10:11 PM cnnx: but im using ncidia driver on linux
10:11 PM orlock: type in glxinfo
10:11 PM cnnx: ok
10:12 PM cnnx: hold on im doing this over ssh on my phone
10:17 PM cnnx: its a bunch of text
10:18 PM cnnx: it says direct rendering yes
10:18 PM cnnx: orlock: ?
10:18 PM cnnx: is that it?
10:18 PM cnnx: hardware?
10:19 PM orlock: Sound like it
10:19 PM cnnx: i did a test yesteday
10:19 PM cnnx: while i played i monitied the ram usage of the card
10:19 PM cnnx: and when im in the game
10:20 PM cnnx: it maxes out to 2gb of used ram
10:20 PM cnnx: out of 2gb
10:20 PM orlock: http://www.x-plane.com/kb/setting-the-rendering-options-for-best-performance/
10:20 PM cnnx: do u play the game
10:20 PM orlock: no
10:21 PM orlock: have you looked through that page?
10:21 PM cnnx: ok ill do the test
10:21 PM cnnx: nice
10:21 PM cnnx: no
10:21 PM cnnx: ill do it now
10:21 PM cnnx: ill start xplane
10:21 PM orlock: go through that page
10:21 PM orlock: it knows more than me
10:22 PM anniepoo: ok
10:22 PM anniepoo: the shell plug is covered with plaster cloth
10:22 PM anniepoo: 8cD
10:22 PM cnnx: hey anniepoo
10:22 PM cnnx: what u doing here
10:23 PM cnnx: orlock: thought we were in ##hardware
10:23 PM anniepoo: cleaning the last of the plaster off my hands
10:23 PM anniepoo: I just coated the plug for the shell with plaster cloth
10:24 PM anniepoo: http://partyserver.rocks/anniepoo/shellLOMpic.jpg
10:24 PM anniepoo: this now has one layer of the stuff they wrap broken legs in
10:27 PM anniepoo: when it dries, it gets a coat of lightweight spackle
10:28 PM anniepoo: tomorrow, basically
10:29 PM anniepoo: 8cD
10:32 PM cnnx: orlock: seems i have low fps
10:33 PM cnnx: like 9fps standing still on runway
10:33 PM orlock: Are you still trying to do this by your phone?
10:33 PM cnnx: no
10:33 PM orlock: Ok, can you paste the output of glxinfo somewhere?
10:33 PM cnnx: ok
10:36 PM cnnx: orlock: https://pastebin.com/25hUA6B0
10:38 PM orlock: Yeah, thats seems like it should be OK
10:38 PM cnnx: ok
10:45 PM z64555: hm? whats this
10:48 PM z64555: uh
10:48 PM z64555: rue
10:48 PM z64555: rue_house: not many people use piezos under an oscillator because then you'd have a phase-locked loop
10:59 PM cnnx: orlock: i got it to 30fps at the lowest quality graphics
10:59 PM cnnx: it sucks that low
10:59 PM cnnx: only ultra high its nice but i get 5fps
10:59 PM * anniepoo is excited to be working on shell
10:59 PM cnnx: a 1070 with 8gb would do it good right
10:59 PM cnnx: anniepoo: are you a woman?
11:00 PM anniepoo: was last time I checked
11:00 PM cnnx: cool.. starting to see more and more on irc
11:27 PM * gottaname|wurk checks anniepoo's plumbing
11:28 PM anniepoo: that's why there aren't more women on IRC
11:32 PM * DagoRed face palms
11:32 PM DagoRed: Really guys?
11:37 PM SpeedEvil: ...
11:37 PM SpeedEvil: idiotd
