00:00 rue_mohr http://eds.dyndns.org/~ircjunk/robots/arm6/p1040192.jpg <-- check it out
00:01 rue_mohr hmm I need to make some retainers
00:02 buhman so I'm an "instructor" at a "math and science camp", and currently we have the kids play with lego, and recently tetrix kits to construct mobile robots from, which we then try to do semi-interesting things with. Last week: http://youtu.be/epEcalArguo http://youtu.be/Y9F-8z0Y76w
00:03 buhman the reason for that is (long story short) some Ph.D thought it would be a clever idea.
00:03 buhman But both my boss (the director) and I agree that to some extent Lego and Pitsco are evil
00:03 rue_mohr so your looking for 12"x12" area
00:03 buhman and my personal goal is to have something that the kids attending can take home and continue learning after the end of the week.
00:03 rue_mohr how many do you need?
00:04 rue_mohr 20?
00:04 buhman 9-12 per week
00:04 rue_mohr PER WEEK?
00:04 buhman per week
00:04 rue_mohr as in + 9-12 per week!?
00:04 buhman that's why it needs to be cheap as hell
00:04 buhman yes
00:04 rue_mohr oh my
00:04 rue_mohr you do have a problem
00:04 rue_mohr and your hearing that from me
00:04 rue_mohr whats the budget for each platform!?
00:05 buhman that's a good question
00:05 rue_mohr or ballpark
00:05 rue_mohr cause what I saw there prolly cost ~$150
00:05 buhman HAHA
00:05 buhman more like $700
00:05 rue_mohr oooh dear
00:06 buhman like I said, evil prices
00:06 rue_mohr anyone here would tel you to be worried when *I* say there is a problem
00:06 rue_mohr will you stay around while I think?
00:06 buhman lego/pitsco charge whatever they want, and it is my goal to fix this
00:06 buhman by excommunicating them from the curriculum here
00:06 buhman rue_mohr: absolutely
00:07 buhman the only thing that takes me off irc is power failure on the server running my irc client.
00:07 buhman (and that doesn't happen very often)
00:08 buhman rue_mohr: so rather than spending crazy amounts of money maintaining these stupidly expensive kits, and not having anything the kids can bring home with them, like I said, I want something that's fairly straightforward to put together, but still allows for some amount of flexibility in how it's constructed.
00:08 buhman and it should be stupidly cheap.
00:09 rue_mohr what needs to be included?
00:09 rue_mohr controller drivers batteries and platform
00:09 orlok buhman: awesome job
00:09 buhman orlok: (if that wasn't sarcasm) I know, I love doing it.
00:10 orlok buhman: and yeah, those kits, while capable of cool stuff, are kinda.. inflexible
00:10 buhman rue_mohr: well the controllers I can handle
00:10 rue_mohr ok
00:10 rue_mohr what interface to drivers
00:10 buhman I planning on expanding the curriculum to include some amount of electronics/computer engineering too.
00:10 orlok buhman: Are soldering irons a no-no?
00:10 buhman orlok: mostly yes
00:11 rue_mohr buhman, will you be using arduinos?
00:11 buhman orlok: and that's the other problem; unless I want to pre-fab PCB's, my only guess is to have them use breadboards, which are fairly expensive
00:11 buhman rue_mohr: absolutely not
00:12 buhman atmegas, probably.
00:12 rue_mohr heh, people rarely understand the difference
00:12 rue_mohr ok
00:12 rue_mohr so if the motor drivers accept pwm/dir your all good
00:12 rue_mohr do they need tachometers?
00:13 buhman or a stepper motor, whichever ends up being cheaper
00:13 orlok buhman: and they are a ghoddamn pain!
00:13 buhman orlok: breadboards?
00:13 rue_mohr I have some ideas that might work for you, but I'v never tried to put them togethor
00:13 orlok yeah
00:13 buhman rue_mohr: me either; that's the problem :P
00:13 rue_mohr buhman, whats the time frame?
00:14 buhman rue_mohr: next year
00:14 rue_mohr ok thats lots of time
00:14 buhman well
00:14 buhman I need to have a half-presentable plan by december
00:14 rue_mohr k
00:14 buhman and I can work out more details as it gets closer to june
00:14 buhman (2013)
00:14 rue_mohr I'd like a ballpark budget
00:14 rue_mohr I use $20
00:15 rue_mohr so I'll go with $80 and see what I can do
00:15 buhman heh
00:15 orlok buhman: any astro related stuff there?
00:15 rue_mohr well *I* could do it for $20
00:15 buhman orlok: astronomy? yes
00:15 buhman we have a fairly nice planetarium among other stuff
00:15 rue_mohr "Anyone can hold Picasso's paintbrush, but only he was screwed up enough to paint what he did"
00:16 rue_mohr how many in total?
00:16 rue_mohr 9-12 per week for how many weeks?
00:17 buhman probably 1-2 the first week
00:17 buhman maximum of 9 subsequent years if all goes well
00:17 buhman first year&
00:17 rue_mohr 52 weeks a year!?
00:17 buhman heh no
00:17 rue_mohr wait, how many weeks are in a year on this planet...
00:17 buhman 9 weeks/year maximum, likely 1-2 weeks the first year.
00:17 rue_mohr DAMN YOU PEOPLE
00:17 rue_mohr ok
00:18 rue_mohr so, at worst, 12*9 robots per year
00:18 buhman best*
00:18 buhman (that would indicate success)
00:18 rue_mohr 6*18 3*36 36+72 8 108 robots a year
00:19 rue_mohr 216 motor sets
00:19 rue_mohr 432 feet of basic frame material
00:19 buhman heh
00:19 rue_mohr hmm
00:20 rue_mohr do you care if its dc motors with tachs?
00:20 buhman that would be excellent
00:21 rue_mohr your velocities there are prolly ~ 36"/sec?
00:21 rue_mohr no
00:21 rue_mohr 18"/sec
00:22 rue_mohr wheel size about 4"
00:22 buhman yeah, and the motors are... 146 rpm (no load)
00:22 rue_mohr where are you located?
00:22 buhman nebraska
00:23 rue_mohr (thats mid usa rue)
00:23 buhman indeed
00:23 rue_mohr I have to go measure soemthing
00:23 rue_mohr katsmeow-afk, ?
00:26 rue_mohr buhman, do you think $80 would be acceptable?
00:26 buhman if that includes *everything* possibly
00:27 buhman just for the chassis, absolutely not
00:27 rue_shop the interval is 50cm rue :(
00:27 rue_shop ok
00:29 rue_shop is 12"x12" a good size tradeoff?
00:30 buhman sure
00:35 rue_shop do youprefer rechargable batteries or standard batteries?
00:37 buhman woah; I wasn't even close to thinking that far forward
00:37 buhman probably rechargable batteries
00:38 rue_shop so you prolly want chargers with that
00:43 buhman erm, how about the chassis?
00:46 rue_shop I'm thinking your best with a flat platic plate thats drilled to attach things to
00:48 buhman heh, ok
00:48 buhman I found a kit that basically works just like that coincidentally
00:49 buhman http://www.pololu.com/catalog/product/761
00:49 ferdna hello
00:50 buhman I really don't want to play with drilling holes myself, so that seems like a fairly reasonable price
00:50 buhman what do you think?
00:50 rue_shop too small, no encoder
00:51 buhman I noticed
00:51 rue_shop the gearmotors are the worst problem
00:51 rue_shop I'm working on that now
00:55 rue_shop I'm down to about $18 for the set less encoders
00:55 rue_shop I think
00:55 rue_shop in the volume your asking for, cant do $20
00:55 buhman what do you ahve so far?
00:56 rue_shop omni wheels, plastic base plate, and a few options for motors, some are gonna take a while to get prices
00:56 rue_shop the rechargable battereis aren't hard, the chargers for them are
00:57 buhman heh, could we bum off power from usb ports? :P
00:57 rue_shop heh
00:57 rue_shop I presumed you want these teatherless
00:58 buhman well, no, I mean charging the batteries via that 5V 500mA usb power.
00:58 rue_shop I have two motor options that can include encoders I can get prices on at some point
00:58 rue_shop I suggest the batteries be 12V
00:58 rue_shop when you start trying to add things to a robot, having less than 12V available makes things awkward
00:59 buhman well, but that would mean I'd need a real transformer too, right ?
01:00 rue_shop I'm trying to find off-the-shelf things
01:00 rue_shop so replacement parts aren't obscure
01:02 buhman wouldn't regulating 12V down to 3.3/5V require a hefty SMPS and/or heatsink?
01:04 rue_shop for logic, its easy, lots of canned solutions
01:05 rue_shop more problem if your using 6V and your batteries flat at 4.5 and your regulators overhead is 2V
01:09 ferdna does the "Arduino Mega 2560 R3" means that there was a firmware change or hardware change?
01:11 e_shop sh
01:13 Triffid_Hunter ferdna: hardware probably
01:13 ferdna Triffid_Hunter, researching...
01:15 buhman I thought perhaps gyroscopes and accelerometers would make suitable replacements for tacho feedback from the motors.
01:15 buhman would certainly make programming much more interesting.
01:16 buhman even a compass
01:17 rue_shop $44 two motors, battery, charger, but no encoders
01:19 rue_shop I need to eat and sleep
01:19 buhman so do I
01:24 rue_mohr katsmeow-afk, ?
01:24 rue_mohr Tom_itx, ?
01:24 rue_mohr :/
01:24 rue_mohr awe, my awesome robot arm...
01:24 rue_mohr poo
01:39 rrywolf curls up on katsmeow-afk for bed
02:28 rue_mohr katsmeow-afk, ?
02:28 rue_mohr you awake?
02:30 rue_mohr http://eds.dyndns.org/~ircjunk/robots/arm6/p1040192.jpg well, it has me excited
03:04 katsmeow-afk .
03:04 katsmeow-afk i was awake and in the other channel
03:08 katsmeow-afk swing couplings ,, and while they look nice, question : you know they make strap-ons for conduit to do that?
03:08 katsmeow-afk http://cloudfront.zorotools.com/product/full/4RHZ4_AS01.JPG
03:10 katsmeow-afk http://www.homedepot.com/webapp/wcs/stores/servlet/QuickViewService?storeId=10051&langId=-1&catalogId=10053&R=100130865&catEntryId=100130865
03:11 katsmeow-afk bbl
09:26 rrywolf stretches out and y
09:27 furrywolf and here I see a mention of strap-ons, and it has nothing to do with any of the type I own. :(
09:54 tsmeow-afk still looks confused about
09:54 furrywolf ?
09:54 katsmeow-afk damn, 45 minutes in "chat" with ups
09:55 katsmeow-afk why you'd need a strapon, how many appendages do you require at once?
09:55 furrywolf because I like being penetrated and I only like women?
09:55 katsmeow-afk oh, they are loaners, ok
09:56 furrywolf ?
09:56 katsmeow-afk you "loan" them to the women so they can use them
09:56 katsmeow-afk words fail me again :-/
09:57 furrywolf heh
09:57 katsmeow-afk i need a picture language,, or large-concept-words
09:57 katsmeow-afk "ragnarock at balderdash"
09:57 katsmeow-afk or whatever the quote is
09:58 furrywolf ... lol?
09:58 katsmeow-afk Tiggr would know
09:58 katsmeow-afk star trek show, the "aliens" spoke in large-concept-phrases
09:59 furrywolf meh, I wanted to get some gardening done today, and it's still drizzling.
09:59 katsmeow-afk "ragnarock at balderdash" ~= "someone came to the rescue and formed a peace treaty and all was well"
09:59 furrywolf lol
09:59 katsmeow-afk i am making 2.5ft tall gloss red address numbers on white background to put on the gate, the damp isn't helping the paint dry
10:00 katsmeow-afk yet another expence to get a service done (package delivery) that should be automatic and normal, but isn't
10:01 katsmeow-afk UPs has another package out with the same delivery guy, and has already flagged it as lost
10:02 katsmeow-afk instead of delivering the package to me with my address clearly and legally posted, they gave the electrnics away to the neighbors with absolutely zero evidence of address showing, not even on their mailbox
10:03 furrywolf ups does that everywhere. heh.
10:03 katsmeow-afk they do it here every other shipment
10:04 katsmeow-afk and being it was delivered Friday, and this is Monday, i do not expect to ever see the package
10:05 katsmeow-afk afterall, the psychpaths could have thrown it over the gate after seeing it has my name and address on it, but they have not done so
10:05 katsmeow-afk incidently, throwing it would have damaged it
10:06 katsmeow-afk all that rain on radar, and none of it here
10:08 katsmeow-afk afk to see the paint dry, and maybe draw outlines
10:12 rrywolf has never found watching paint dry to be very interes
10:17 furrywolf grrrr, looks like today's flight might be really late.
10:19 furrywolf should take off in a few minutes... instead it's still a half hour from landing at the previous stop...
10:30 Squint difficult to see how those aliens learnt what the large phrases meant
10:30 Squint if they didn't have small ones with which to explain them
10:31 Squint like trying to implement java without a C compiler :)
10:36 red-1 Hello everyone, anyone knows how Google deals with the Velodyne Lidar on the google car ?
10:37 furrywolf not I.
10:41 Tom_itx why would it need one?
10:43 red-1 hi furrywolf thanks
10:45 rue_bed if java had been thought up by people who knew what assembler even was, it wouldn't be the java we know today
10:45 Tom_itx rue_bed i saw your arm
10:49 rue_bed good morning
10:49 rue_bed what did you think so far?
10:52 Tom_itx looks good but will the screw crush the thinwall tubing?
10:53 furrywolf grrr, plane should be here now. hasn't taken off yet.
10:58 Sunnyday Hi guys
11:06 red-1 hi !
11:09 Sunnyday How are you red-1?
11:09 rizlah If I leave a phone charger in a socket, does it still use electricity if not charging anything?
11:09 Squint rizlah, probably
11:09 furrywolf yes
11:09 rizlah I see
11:10 furrywolf just not as much.
11:10 rizlah So best to unplug everything that isn't used?
11:10 rizlah Always assumed the circuit was broken somehow if not connected
11:11 red-1 good and you Sunnyday tank you... what r u up to in robotics ?
11:11 furrywolf look up "phantom load" or similar terms.
11:15 furrywolf yay, plane is finally on the way.
11:15 Sunnyday Solar tracking robots
11:16 Sunnyday Been tracking round town today looking for prams for our soon-to-be son/daughte
11:16 Sunnyday r
11:19 red-1 hoo
11:23 rue_mohr katsmeow-afk, mine are pinned thru
11:26 furrywolf http://www.theregister.co.uk/2012/07/01/edison_battery_speeded_up/ they've finally found something better than edison's nickel flake.
11:27 furrywolf "The Stanford team has created an ultrafast nickel-iron battery that can be fully charged in about 2 minutes and discharged in less than 30 seconds. "
11:28 Sunnyday Nickel Iron makes a great rechargable battery, shame its power to weight ratio is shite
11:29 furrywolf bbl, time fo work
11:29 Sunnyday Lithium Thionyl Chloride has the BEST albeit ONE CHARGE, LiFePo and Silicon Nanowire are the best power to weight ratio rechargable
11:29 Sunnyday Silicon nanowire is not commercially available
11:29 Sunnyday custom made only
11:30 Sunnyday None of them beat petrol in terms of power to weight ratio
11:32 red-1 solar panels beats it :)
11:41 Sunnyday CIGS is the best type of solar panels, more than twice the watts per square meter generated than silicon
11:41 Sunnyday Copper Indium Germanium Selenide
11:42 Sunnyday There are specialist ones better than that, but again its ring up the company. CIGS is available to buy online now with a click of a button
11:42 Sunnyday Anything higher you got to ring the company up and do bank wire
11:42 Sunnyday CIGS are good enough to use in solar powered UAVs
11:43 Sunnyday Probably good enough for the desert too
11:43 Sunnyday Expensive tho
11:43 Sunnyday http://www.outdoor-ranger.co.uk/brunton-solaris-26w-solar-charger-p-9867.html?currency=GBP&amp;language=gb
11:53 rue_mohr katsmeow-afk, I noticed they only said the town it was deleivered to
11:53 rue_mohr katsmeow-afk, wait!
11:53 rue_mohr how about I send you a small package with $1M insurance on it, WHEN they lose it you can claim the money!
11:53 rue_mohr !?!!?
11:54 Sunnyday How do you ensure the package gets lost tho?
11:54 rue_mohr katsmeow-afk, I have a hundred small shipping boxes canwe do that?
11:54 rue_mohr they will not deliver the package to her
11:54 rue_mohr they never do
11:55 rue_mohr katsmeow-afk, katsmeow-afk can we do it!?
11:55 rue_mohr pleeeeeeeeeeeeeeeaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaase?
11:59 Sunnyday To pay for the insurance would cost a lot
11:59 Sunnyday You're better off filling an old banger with loads of people and reversing into a truck
12:00 rue_mohr I want to know how much
12:00 Sunnyday 5 whiplash backpain payments
12:00 Sunnyday Make sure all 5 of them say the same story
12:00 rue_mohr no, your not understanding, this is a chronic problem with kat and ups
12:00 Sunnyday hahahahahha have a nice holiday
12:00 rue_mohr they just gave a scope and 36G of ram to the neighbour that continiously sues her
12:02 rue_mohr a tektronics scope
12:03 rue_mohr damn kat, where did you get to
12:03 rue_mohr Tom_itx, your not around either are ya?
12:03 Sunnyday A lot of money in lawsuits
12:03 rue_mohr its easy, they lost the package, they pay the money
12:03 Sunnyday I made 20k once I won a case
12:04 Sunnyday Spent the whole lot on a 4x4 with leather seats, AC speakers, weed, girls, holidays all gone now
12:04 rue_mohr me and kat could sit back and get ups to pay her credit cards off by me just shipping packages to her
12:05 rue_mohr I could do it pretty legit as 'art'
12:05 rue_mohr make a little thing and send it to her
12:05 rue_mohr when they lose it, the money gets claimed, we do it again
12:06 rue_mohr till they stop mis-delivering them
12:07 Sunnyday The postal company might launch an investigation for that amount
12:07 rue_mohr they should!
12:07 Sunnyday Insure it for something sensible like $1200
12:07 rue_mohr their delivery guy is intentionally taking the packages to the wrong house!
12:07 Sunnyday OMG what if it gets returned to sender?
12:07 rue_mohr no, her neighours prolly throw away or destroy any packages for her
12:07 rue_mohr but she cant sue them for that
12:08 Sunnyday They need a signature, if the delivery company has no signature you can sue
12:08 rue_mohr she wont win because she's single and down in alabama that gives her no rights
12:08 rue_mohr nono
12:08 rue_mohr I dont want them not to screw it up, I want them to compensate
12:09 rue_mohr I could send her a package I *KNOW* they would skewr with a forklift
12:09 rue_mohr ups screws up EVERY delivery
12:09 rue_mohr somehow
12:10 rue_mohr I'v love to do it just to make them pay
12:10 rue_mohr all the ***-**** stuff they have done to me
12:11 rue_mohr thats an exciting idea
13:23 rue_mohr ugh, kats gonna ignore me for 3 days now
13:29 Tom_itx need any phone test equipment?
13:29 Tom_itx not sure what all it is, there's one that tests fiber
13:29 Tom_itx local guy got some stuff in
13:29 Tom_itx used
13:30 KongfuPanda I think I'm gonna work on my home-made hexapod
13:31 KongfuPanda or I might give in to World of Warcraft due to boreness
13:31 KongfuPanda boredom *
13:50 rue_mohr Tom_itx, is there a laser pen thing with a fiber optic connector on the end?
13:51 rue_mohr he left
14:32 rue_shop sometimes our channels here dont help me shed that loneley feeling
14:33 furrywolf heh
14:33 rrywolf just got back from
14:34 rue_shop oh yea, its a work day in most of the world
14:35 rue_shop I got a glue gun head to help me with ideas on a 3d printer head
14:39 rue_shop 9.5mm rod is substitutable for 3/8"
14:47 buhman rue_shop: hello
14:53 rue_shop hey
14:55 katsmeow-afk hay
14:56 rue_shop kat...
14:56 katsmeow-afk i drove into Bham to the distribution center, while it was obvious they recognised my name, they said they had no clue what "this" was about
14:56 rue_shop did you give them the ship number?
14:57 rue_shop when I phoned, it was on computer
14:57 rue_shop hey
14:57 katsmeow-afk of course, why do you ask that?
14:57 rue_shop will you let me send you, via UPS you a verry expensive (insured) piece of artwork?
14:58 rue_shop before you put up your 10' tall glowing numbers?
14:58 katsmeow-afk of course
14:58 katsmeow-afk oh
14:58 rue_shop hmm?
14:58 furrywolf lol
14:58 katsmeow-afk well, they do need another coat of paint, but i was hoping to put them up in a few days
14:58 rue_shop say, worth, maybe $800?
14:58 rue_shop more?
14:58 katsmeow-afk sure, but won't insurance cost $$$ ?
14:59 rue_shop let me find out, you know I cant find out till I have somewhere to ship to <:-|
14:59 katsmeow-afk you have my adddy
14:59 rue_shop no, I had you po box
15:00 katsmeow-afk ummm
15:00 rue_shop I'm working on a robot, so, do whatever you like
15:00 furrywolf someone shipped a huge painting with the company I work for... when I went to pick it up, it was obviously extremely badly damaged. I told him I was going to photograph it in his driveway, with him in the shot, before I would take it.
15:01 katsmeow-afk hmm
15:01 furrywolf just to make sure it wasn't rue_mohr. :P
15:01 katsmeow-afk arrrrrrrrrrrrggggggggg
15:05 GuShH hi katsmeow-afk
15:05 rue_shop hey I dont have to weld metal togethor, I can bolt them
15:06 katsmeow-afk or pin them
15:06 katsmeow-afk dovetail them even
15:07 katsmeow-afk assemble it with no fasteners like a "chinese puzzle", then one roll pin at the end
15:07 rue_shop I think I need to take apart some batteries for some counterweight lead
15:07 rue_shop katsmeow-afk, hehe
15:07 katsmeow-afk i did that with a whole wall of windows once, ny stepfather was so pissed ,, took him over a week to take it down so he could reassemble it with nails
15:09 Tom_itx rue_mohr i dunno what it was. it was in a large expensive carry case with a 9" or so lcd screen. floppy drive on the side
15:10 katsmeow-afk Compaq
15:10 Tom_itx amongst a whole pile of other phone test equipment
15:10 Tom_itx i don't think it was compaq
15:10 katsmeow-afk Commodore made one C64 that looked like a Compaq
15:10 Tom_itx if there is minor interest i may be able to get model #s
15:11 Tom_itx no no this was fiber test equipment
15:11 Tom_itx and other phone test stuff
15:11 rue_shop hah, prolly just a reflectometer :/
15:12 Tom_itx probably 10 or 15 pieces in all
15:12 rue_shop if its a tdr, you should just send it to me, I wont charge you for disposing of it :)
15:12 Tom_itx the guy brought it in to sell. i just happened to be there when he did
15:12 katsmeow-afk that's real generous offer
15:13 rue_shop Tom_itx, you have my interest, take some pics or something eh?
15:14 Tom_itx just the one piece or all of it?
15:14 katsmeow-afk rue can prolly use a single bouncer gadget at work at least once a week
15:14 Tom_itx it's all in cases
15:14 katsmeow-afk the tdr
15:14 katsmeow-afk "tdr" = "signal bouncer gadget"
15:15 rue_shop I think I'm not the only ones who's excited
15:15 Tom_itx there was one piece nobody seemed to know what it was
15:15 Tom_itx it may be overpriced too. i have no idea yet
15:15 rue_shop "Anyone seen a large robot arm around? .... I was just building it..."
15:15 katsmeow-afk it was hopping down the street when i drove up?
15:16 furrywolf http://www.affordable-solar.com/store/solar-panels/CSI-CS6P-235PX-235W-Solar-Panel
15:17 katsmeow-afk woah,, they hit $1/watt , is it new?
15:17 furrywolf first time I've seen real panels under $1/watt for proper a-grade panels, not seconds.
15:17 katsmeow-afk "Canadian solar delivers uncompromising values to is customers across the globe.
15:17 katsmeow-afk "
15:17 katsmeow-afk <cough>
15:18 furrywolf http://www.affordable-solar.com/store/solar-panels/schott-poly-230-230-watt-solar-panel for an extra 6 cents/watt, you can get made in usa panels.
15:18 katsmeow-afk but it's a canadian company
15:19 katsmeow-afk Data at normal operating cell temperature (NOCT)
15:19 katsmeow-afk Nominal power [Wp] Pmpp: 165 watts
15:20 katsmeow-afk Schott Poly 230, 230W Solar Panel
15:20 katsmeow-afk wierd the otehr 60 watts go to?
15:20 furrywolf panels dislike heat.
15:20 furrywolf those numbers are probably at 50C instead of 25C or something.
15:21 katsmeow-afk oh,, so don't leave them out int he sun, gotcha
15:21 furrywolf panels make more power on cold days than hot ones.
15:21 furrywolf especially with a good mppt charge controller.
15:22 katsmeow-afk fan?
15:22 katsmeow-afk water cool them?
15:22 furrywolf mounting them well off the roof is generally the best way. if you put them on 8" legs, you get much more power than if you put them right on top of the roofing.
15:22 katsmeow-afk what temperature is the output dropping noticable? or is it a linear curve?
15:23 furrywolf but putting panels right on top of the shingles to avoid annoying the neighbors is standard these days.
15:23 katsmeow-afk how is floating panels off the roof "annoying" ?
15:23 furrywolf it looks different than their house.
15:23 furrywolf it looks useful.
15:24 katsmeow-afk i think it's a great idea, calling them "energy producing shade devices"
15:24 furrywolf you mean energy stealing eyesores? haven't you learned anything about neighbors? :P
15:24 katsmeow-afk yea, we call them difefrent things
15:25 katsmeow-afk "dogs" , "gods" , etc
15:26 katsmeow-afk http://www.affordable-solar.com/store/solar-inverters-accessories-cables <<== no sine convertors
15:26 furrywolf in any case, flush mounting is standard now, and like those numbers show, greatly hurt output.
15:26 furrywolf on the flip side of the coin, if you mount them spaced off the roof, on a nippy morning they'll put out well over their rating.
15:32 katsmeow-afk .
15:36 rue_shop hahah
15:36 rue_shop these 2" cina clamps can ALMOST do 2"
15:44 rue_shop katsmeow-afk, know anything about "204" rod?
15:50 furrywolf bbl, back to work.
16:04 Tom_itx rue_shop sounds like a stainless rod
16:06 rue_shop that would expain why it just balls up and dosn't wanna stick to steel
16:11 Tom_itx i don't see it though
16:11 Tom_itx hard to say what it is
16:13 Tom_itx try reversing the polarity
16:17 Tom_itx or better yet, get some decent welding rod
16:18 rue_shop its the only small stuff I ahve now
16:18 rue_shop I thought it was close to 6011 when I got it
16:18 rue_shop cause of soemthing I read off the box
16:19 Tom_itx 7018
16:20 Tom_itx http://www.lincolnelectric.com/en-us/consumables/stick-electrodes/Pages/stick-electrodes.aspx
16:21 Tom_itx 7014
16:21 Tom_itx i think that may be what i had
16:37 rue_shop " THUMP THUMP THUMP" "HEY!!! THATS PRECISION EQUIPMENT! WHY ARE YOU HITTING IT WITH A HAMMER!!?!?!" "bolt wont go in...."
16:53 gongoputch Tom_itx: mind a brief /pm ?
17:02 katsmeow-afk 204 is a type of stainless steel, but i dunno of a "E204 rod"
17:06 rue_shop ugh, so its stainless
17:07 rue_shop it just says 204
17:09 katsmeow-afk well, i dunno that it is, you don't generally use a rod of exactly the same base metal, so to weld a 204 ss, you wouldn't have a 204 rod
17:09 katsmeow-afk what's it look like?
17:10 katsmeow-afk and do you have enough to make worrying about it worthwhile?
17:13 tsmeow-afk goes to see if that package got deliv
18:06 rue_mohr what dd they say kat?
18:07 rue_mohr they told me that on tiesday that number could be called and they would 'try t sort it out'
18:09 rue_mohr kat, did you see the new arm I'm playing with?
18:10 Tom_itx ok, got some decent din connectors. maybe these will be a better physical connection than the original ones
18:10 Tom_itx got the holes modded for them, soldering atm
18:24 gongoputch Tom_itx: is it safe to have the USBTiny mkII connected to an Arduino while the USB is connected?
18:26 Tom_itx you can power the arduino with it but if you have external power, you should flip the switch for target power
18:27 gongoputch I thought you would say that.
18:27 Tom_itx do you have a power supply on the arduino?
18:27 Tom_itx it may not harm it but i wouldn't recomend it
18:27 Tom_itx if the target voltage exceeds the USB voltage it may blow out the translator chip
18:27 gongoputch no, it is just USB powered ATM, but me and my big fat fingers busted the little switch :(
18:28 Tom_itx yeah it's pretty tiny
18:28 Tom_itx can you use a knife tip to switch it?
18:28 gongoputch I haven't dared yet.
18:28 Tom_itx which programmer do you have?
18:28 gongoputch one of those D'OH! moments
18:29 gongoputch mkII, in the nice plastic case
18:29 Tom_itx ok the blue one
18:29 Tom_itx and where are you?
18:29 gongoputch I am able to program my Leo with it
18:29 gongoputch DE, USA
18:30 gongoputch I thought I was having troubles with the programmer, it is the leonardo (on freebsd)
18:30 Tom_itx that switch it a bit tricky to replace. i could send you another one if you want or if you wanna send it to me i'll fix it for you
18:30 Tom_itx it's easy to screw up the traces replacing it
18:31 gongoputch thats awsome, I did look at it some, microscopic to these eyes.
18:31 Tom_itx it's a bit tricky to get back in the case too
18:31 Tom_itx so it's up to you
18:32 Tom_itx i screwed up a couple early on until i figured out a good way to install them
20:20 GuShH katsmeow-afk: got the cheap air compressor seller to dig up the specs, it's 1700W so roughly 2.3HP of the 2.5HP they boast.
20:20 rue_mohr does it have a crank?
20:21 GuShH rue_mohr: what do you mean?
20:21 GuShH katsmeow-afk or furrywolf argued there was NO WAY these were 2.5HP
20:21 rue_mohr maybe you have to add the extra .2hp yourself
20:21 GuShH "more like 0.5hp" or something like that was said
20:21 rue_mohr is it 230V?
20:22 GuShH yes
20:25 GuShH rue_mohr: why?
20:26 rue_mohr cause if it was 120 I'd tell you something was still wrong
20:26 GuShH rue_mohr: I'm more worried about the regulators and overall quality of the unit at this stage than whatever specs they boast on paper.
20:27 rue_mohr what are you using it for?
20:28 GuShH painting mostly, but I always wanted a sandblasting setup and for that I'd need a bigger tank if I want to work on big pieces
20:28 GuShH likewise with sanders
20:28 rue_mohr hp or lp painting?
20:29 GuShH that depends on the job
20:29 GuShH and likewise the work size, you wouldn't need a huge stored volume for small pieces.
20:30 rue_mohr lp your gonna need a lot of air
20:33 rue_mohr if you were gonna get something for a dollar off ebay,
20:33 GuShH rue_mohr: there's also what I can get and what I'd like to get, which often never meets.
20:33 rue_mohr of the following things
20:33 GuShH right now I have some money I could spend on a cheap air compressor to paint the house
20:33 rue_mohr what would you get
20:34 GuShH or try to spend the same amount of money on a dude that I know will do a poor job
20:34 rue_mohr http://www.ebay.ca/itm/NEW-1mW-2in1-Red-Laser-Pointer-LED-Lamp-Key-ring-W-C-/130481300331?pt=US_Laser_Pointers&hash=item1e614aa36b

20:34 GuShH the led display module sounds nice
20:34 rue_mohr yea the chip
20:34 GuShH oh it's a max7219 only
20:35 rue_mohr yea
20:35 GuShH bummer
20:36 rue_mohr so maybe the 5000+ mcd white leds?
20:36 GuShH sounds like the best choice
20:36 GuShH otherwise the laser pointer looks cheap
20:37 GuShH I think I have one of those somewhere
20:37 rue_mohr but it would be a toy!
20:37 rue_mohr 20 of the rectangular leds!
20:37 GuShH at 1mW you use it with your cats
20:38 GuShH rue_mohr: I don't like rectangular LEDs because they're hard to use in most cases.
20:38 rue_mohr I need a 5mw for testing optic fibers
20:38 rue_mohr graphics!
20:38 rue_mohr bar graphs
20:38 GuShH good for bargraph type displays, but still harder to mount on an enclosure than a regular led

20:38 GuShH rue_mohr: testing as in "it's not broken" ?
20:39 rue_mohr cmon, what would you pick?
20:40 rue_mohr oops, I'm over a dollar now
20:40 rue_mohr those are my choices
20:40 GuShH rue_mohr: what do you need??
20:40 rue_mohr nothing
20:41 ShH doesn't just buy stuff because it costs less than a do
20:41 rue_mohr I'm buying stuff so it shows up in the mail
20:41 rue_mohr if I buy 1 thing every day, it's only $365/year till I die
20:43 rue_mohr I like the idea of buying the chip, cause I can sit down and play with it for a while
20:43 rue_mohr that or the toy
20:44 rue_mohr I'm gonna get the chip
20:45 rue_mohr done
20:46 rue_mohr wonder what I'll buy tommorow
20:46 katsmeow-afk .
20:46 rue_mohr katsmeow-afk, can you find me an interesting buy-it-now for $1 on ebay for me to buy tommroow?
20:47 katsmeow-afk define "interesting"
20:47 rue_mohr kat, I'm working on metal 'extension' hands for working with hot stuff
20:47 rue_mohr interesting, that which
20:47 rue_mohr generates a finite amount of interest
20:47 katsmeow-afk interest in what , specifically?
20:47 rue_mohr it
20:47 rue_mohr :)
20:48 rue_mohr I just bought the maxim chip
20:48 katsmeow-afk so i guess wildly
20:48 rue_mohr if it would interest you, it would likley interest me
20:48 katsmeow-afk k
20:48 rue_mohr thats why I ask you and not someone else
20:49 katsmeow-afk k
20:49 rue_mohr you lost a thread

20:52 rue_mohr I used one of the big bearings I modifed for the base
20:52 katsmeow-afk this puter is slow as tar today
20:52 rue_mohr I wanted to use them on something else, but I'm gonna die soon and its kinda a use-it-or-lose-it thing
20:52 katsmeow-afk truck bearings
20:52 rue_mohr "nothing is too special to be used"
20:53 rue_mohr I'd welded some washers to them a long time ago
20:53 rue_mohr real nice-like
20:53 rue_mohr (it still turned when I was done)
20:54 katsmeow-afk i am not seeing how you'll actuate this arm, or if it replaces that 8ft arm, or what you'll do with green poka-dot curtains
20:54 rue_mohr I object, that was a pillowcase
20:54 katsmeow-afk ok
20:55 rue_mohr actuating it is easy, I dont bother with that bit yet
20:57 rue_mohr do you like the idea of metal hands?
20:57 rue_mohr good enough to weld with and then you can pick up and manipulate the hot stuffs?
20:57 katsmeow-afk no feedback with them
20:58 rue_mohr not electronic, cable
20:58 rue_mohr so full feedback
20:58 katsmeow-afk same problem robots have, no sense of pressure or texture or force-direction
20:58 rue_mohr well, you dont feel texture much anyhow anyway, right?
20:58 rue_mohr hmm
20:58 katsmeow-afk sure you do, you can tell of you're picking up a 1/4 w resistor or a 3300ufd cap
20:59 katsmeow-afk you can tell pretty fast if the leads are kinked
20:59 rue_mohr I been trying to work out how to make the machine fit around the organic, maybe I should make the organic fit around the machine
21:04 katsmeow-afk afaik, the reason Skynet put organics on the robots was for density and versatility of the organic senors

21:24 furrywolf worked all day!
21:24 katsmeow-afk all day today spent on UPS, and there's 20 things i could have been doing
21:32 rue_mohr they said to call that special number tommorow
21:33 katsmeow-afk why?
21:35 rue_mohr thats what they said for correcting it,
21:35 rue_mohr I was having a heard time hearing, my system was flooded in static
21:36 katsmeow-afk correcting what?
21:36 rue_mohr the line interface is all screwball and picks up all sorts of annoying noise
21:36 rue_mohr your mis-delivered package
21:36 rue_mohr using the phone number I said
21:36 katsmeow-afk he got it tonite
21:36 rue_mohr uh
21:37 rue_mohr they did it with another package?
21:37 rue_mohr already?
21:37 katsmeow-afk yeas
21:37 rue_mohr fffffff
21:37 katsmeow-afk yeas
21:37 rue_mohr I'll mail them a bomb
21:37 rue_mohr :) no
21:37 rue_mohr sorry
21:37 rue_mohr do you have the phone number they gave me?
21:37 katsmeow-afk the delivery guy was scared ,,, bad , didn't even want his pen back
21:37 katsmeow-afk no
21:38 rue_mohr wait
21:38 rue_mohr you found him?
21:38 rue_mohr did you get your package?
21:38 katsmeow-afk i did not find the guy who screwed up
21:38 rue_mohr dosn't matter who goes back for the package
21:38 katsmeow-afk i know that
21:39 rue_mohr so when did you get a chance to talk to another driver?
21:39 katsmeow-afk 8pm
21:39 rue_mohr what did they have you sign?
21:39 katsmeow-afk i didn't sign anything
21:39 e_mohr scratches his
21:39 rue_mohr how did you end up with his pen?
21:40 katsmeow-afk he wanted me to sign that he could leave packages at the gate, or wherever,, and i said that "wehreever does not include the neighbor;s, so no"
21:40 rue_mohr so did you call them about mis-delivering another package?
21:40 katsmeow-afk you're confusng me rue, why wuld i want them to misdeliver another package?
21:41 rue_mohr no I mean about correcting it
21:41 katsmeow-afk is there another one missing?
21:41 rue_mohr did you ask them to correct the 2nd mis-delivered package?
21:41 katsmeow-afk he brought it today
21:41 rue_mohr did you just say that they delivered another pacakge to your neighbour?
21:41 katsmeow-afk he also brought the mis-delivered one
21:41 rue_mohr to you or your neighbour?
21:41 rue_mohr oooh
21:41 rue_mohr you have all your package?
21:41 tsmeow-afk s
21:42 rue_mohr I know there are 2 boxes involved, but I dont know if you have them or your neighbour has them
21:42 furrywolf I once was waiting for a package, waiting... got a tracking number from the seller, it had been delivered days ago. Went to ask my neighbors if they had it, found it sitting on the porch of one who was away, along with several other people's boxes.
21:42 katsmeow-afk if they had fusked up agian, would i be sitting here calmly, being frustrated at you?
21:42 furrywolf UPS does not seem to impress their drivers with the need to get packages to the right place, just the need to finish their route as soon as possible.
21:42 rue_mohr yes
21:43 rue_mohr so, if I send you an insured package, are the odds better than 60% that your neighbour will get it?
21:43 katsmeow-afk furry, in this case it would have been a LOT faster to leave it with me
21:43 rue_mohr katsmeow-afk, do you have your scope?
21:43 katsmeow-afk rue, i dunno
21:43 katsmeow-afk i got what i ordered
21:43 furrywolf you can send it back and forth until he does. :P
21:44 rue_mohr it costs a bunch to insure it, well to send it, but we could make money if its almost garunteed they would lose it
21:44 rue_mohr katsmeow-afk, hows the scope?
21:45 furrywolf I've noticed that, at least for USPS, the insurance sticker makes the box much more likely to show up.
21:45 katsmeow-afk furry, i painted 3 pieces of roofing tin gloss white, and put 30 inch tall chars on each in gloss red , you can now see my address as far as the horizon
21:45 rue_mohr damn its not just subtext?
21:45 furrywolf insured items get scanned at more steps, and they seem to try harder not to lose them.
21:45 rue_mohr katsmeow-afk, if I send you an insured package and you get it, would you take pics for me to see what it looks like when it gets there?
21:46 katsmeow-afk yeas
21:46 furrywolf I got my Peltier on saturday... now to figure out how to turn it into an ant trap. :)
21:47 katsmeow-afk spray it with glue, lay it outside
21:47 furrywolf no. :P
21:47 rue_mohr put a fast freezing liquid on it, mixed with sugar
21:48 furrywolf my plan is to put a heatsink on the bottom, the peltier, an aluminum plate, then a half-empty soda can, and some foam insulation. Let the ants start a column into the soda, then switch it on, and let them keep freezing as they keep marching in.
21:48 katsmeow-afk you're ging to spend how many watts to kill one ant?
21:48 rue_mohr hehe
21:48 furrywolf at another house I lived at, I was gone for a couple weeks, and came back to find the ants had found something in my freezer they'd liked... and comitted mass suicide, forming a half inch thick layer of dead ants in the freezer.
21:49 rue_mohr did you see the arm update?
21:49 rue_mohr yes
21:49 rue_mohr yo commented on it
21:49 rue_mohr she did
21:49 rue_mohr pay more attention
21:49 rue_mohr but
21:49 rue_mohr whatever
21:49 furrywolf I'm hoping I can get this to happen again, but with a disposable ant collector (soda can)...
21:50 rue_mohr ants cant get out of teflon pots.
21:50 furrywolf the ants are really hurting my garden, by farming aphids, and eating the eggs from the ladybugs I buy to eat the aphids...
21:50 katsmeow-afk you know there's ant killer stuff?
21:51 rrywolf has an organic ga
21:51 katsmeow-afk i let a few small ant hills stay around the house because they eat termites, and anywhere i don't go i leave them alone, but if i need to weedwhack somewhere , they are gone
21:52 katsmeow-afk not much worse than a anthill full of pissed off ants that's all suddenly become airborne
21:53 furrywolf hrmm, I could just hold the aluminum plate, peltier, and heatsink together with rubber bands... don't need too much force as long as it's all greased well.
21:53 rue_mohr Ineed to understand more about what motivates me
21:53 furrywolf but first, dinner. brb.
21:53 katsmeow-afk there's some anthills i let stay near the concreted driveway, and the lil suckers removed enough dirt under the concrete that i hit it with a board the driveway sounds hollow
21:54 katsmeow-afk food sounds good
21:54 katsmeow-afk fish, praps
21:54 katsmeow-afk i gotta get that pump installed tomorrow
21:54 rue_mohr my grandmothers old place had that problem, the corners snapped off the segments cause they were undermined
21:55 rue_mohr katsmeow-afk,
21:55 katsmeow-afk rue_mohr,
21:55 rue_mohr how do you keep a 2000gallon outdoor tank of drinking water from freezing in the winter?
21:55 katsmeow-afk you don't let it get cold
21:55 LoRez rue_mohr: you bury it.
21:55 rue_mohr oh
21:56 rue_mohr what if its topless
21:56 katsmeow-afk my plan was to put 500 gallons in the cellar, where it won't freeze
21:56 rue_mohr oh
21:56 e_mohr looks over furrywolfs shoulder, coding anything interest
21:56 katsmeow-afk i can top it up any time in winter, beause there's water,and it won't stay below freezing here longer than a week or two
21:56 katsmeow-afk afk, bbiaf
21:58 furrywolf nope. I don't do much coding these days. all my projects are related to survival, not fun.
22:02 furrywolf d'oh. the contact area on the heatsink I want to use is smaller than the peltier.
22:04 rue_mohr from the elbow, what order do you think the wrist pitch and rotation should be in?
22:06 e_mohr knocks on the wi
22:06 rue_mohr katsmeow-afk,
22:13 rue_mohr I suppose if I were alone I'd seek intelligence
22:14 rue_mohr maybe I should get on that
22:15 Tom_itx one thing led to another....
22:15 rue_mohr life!
22:15 rue_mohr TAKE ME 2 OF YOUR LEADERS!
22:16 Tom_itx rewired
22:18 rue_mohr 7,375,927,931 km
22:19 rue_mohr pluto is 410 light-minutes away
22:19 rue_mohr 7 hour ping time
22:21 rue_mohr dont know the propigation delay on gravity
22:25 rue_mohr hmm
22:27 rue_mohr if you have a conductor that exerts an electromagnetic frequency, the higher the freq, the more other conductors around it are charged based on the capacitance between them
22:29 Tom_itx hot diggety.. it all still works
22:29 katsmeow-afk well paint me blue and call me,, wait, that's been done... umm....
22:30 rue_mohr smurf
22:30 ace4016 kinky
22:30 tsmeow-afk had problems with that show, as you can ima
22:31 rue_mohr !?
22:31 katsmeow-afk only one female in the entire smurf world, and they used "surfette" as her nick even tho she wasn't all that small
22:31 rue_mohr hmm
22:32 ace4016 they produce large litters and live a really long time, until they give birth
22:32 orlok she was invented by gargamel
22:32 katsmeow-afk o
22:32 rrywolf bets gay marriage is legal in smurf
22:32 orlok invented/created
22:32 katsmeow-afk furry, it would haveto be
22:33 katsmeow-afk millions of male smurfs and only one breeder?
22:33 orlok no evidence of breeding either!
22:33 rue_mohr ok ok I'm sorry I brought it up
22:33 orlok it must have been asexual reproduction
22:33 orlok smurfette wasnt a "real" smurf
22:34 katsmeow-afk no?
22:34 furrywolf maybe there's amazon lesbian smurfs somewhere else, and there's really a 50/50 male/female population?
22:34 orlok she was artificially created by gargamel
22:34 orlok as a trap
22:34 orlok but she was won over by the goodness of the smurf way
22:34 rrywolf knows roughly nothing about sm
22:34 katsmeow-afk to lure out the str8 smurfs to be put to death?
22:35 rue_mohr man I'm really sorry I brought it up
22:35 rue_mohr geeesh
22:35 orlok http://www.google.com/url?sa=t&rct=j&q=donny%20darku%20smurfs&source=web&cd=2&ved=0CE0QtwIwAQ&url=http%3A%2F%2Fwww.youtube.com%2Fwatch%3Fv%3Ds-rGGmXpLjw&ei=4GXyT5myM8ySiQfKk-zOAw&usg=AFQjCNFNPpGVIgcqjV3ukQDIAB0DDjQ1VQ&cad=rja
22:35 katsmeow-afk lol@rue
22:35 orlok http://www.youtube.com/watch?v=s-rGGmXpLjw i mean
22:35 orlok donny darko said it best
22:36 katsmeow-afk what did he say? i have no sound here
22:36 orlok Donnie: First of all, Papa Smurf didn't create Smurfette. Gargamel did. She was sent in as Gargamel's evil spy with the intention of destroying the Smurf village, but the overwhelming goodness of the Smurf way of life transformed her. And as for the whole gang-bang scenario, it just couldn't happen. Smurfs are asexual. They don't even have reproductive organs under those little white pants. That's what's so illogical, you know, about being a Smurf. What's

22:36 Tom_itx those connectors are much better on the steppers
22:36 GuShH http://www.youtube.com/watch?v=dp2tsPlWid8
22:37 furrywolf maybe they're herms, and change genders when needed?
22:37 katsmeow-afk mic connectors to the servos?
22:37 rue_mohr HEY EVERYONE!
22:37 katsmeow-afk HEY RUE!
22:37 Tom_itx kat, yes
22:37 rue_mohr did you see the robot arm I framed out!!?
22:37 Tom_itx a new one or yesterdays?
22:38 rue_mohr http://eds.dyndns.org/~ircjunk/robots/arm6/p1040197.jpg
22:38 rue_mohr check it out, yay!
22:38 rue_mohr http://eds.dyndns.org/~ircjunk/robots/arm6/p1040211.jpg
22:38 katsmeow-afk why is there a hole in the tabletop?
22:38 rue_mohr robot, woooo
22:38 orlok wheres the rest of the lamp?
22:38 rue_mohr which hole?
22:38 rue_mohr its not a lamp!
22:38 rue_mohr its made from EMT
22:38 orlok :)
22:38 orlok EMT?
22:38 Tom_itx conduit
22:38 orlok uh, nice base
22:38 katsmeow-afk in the desk in http://tom-itx.dyndns.org:81/~webpage/cnc/psu/control7.jpg
22:39 rue_mohr http://eds.dyndns.org/~ircjunk/robots/arm6/p1040191.jpg
22:39 rue_mohr those little joiners were fun to make
22:39 GuShH rue_mohr: what do you use those cheap c clamps for? I got a set and destroyed them all the first time.
22:39 rue_mohr nice tom
22:39 rue_mohr GuShH, anything that dosn't involve serious clamping
22:40 GuShH I refuse to buy another set
22:40 katsmeow-afk good way to make them tho, the proportions worked out nicely,, good thing you hoarded that channel , no?
22:40 ShH can see the gutted hot glue
22:40 rue_mohr I bought them individually
22:40 rue_mohr its gonna be a balanced arm
22:40 rue_mohr http://eds.dyndns.org/~ircjunk/robots/arm4/p1010990.jpg
22:40 rue_mohr like that
22:41 tsmeow-afk wold like to see it mo
22:41 rue_mohr :)
22:41 katsmeow-afk my brian si two steesed out to imaine it now
22:41 rue_mohr you just wanna see how I'm gonna attach the motors
22:41 rue_mohr I do to
22:42 katsmeow-afk i woke at 1am this morning wondering how badly damaged the neihbors did to my stuff and how much moeny this fiasco was gonna cost me
22:42 rue_mohr I'm not sure about the wrist yet either
22:42 katsmeow-afk i been a wreck all day
22:42 katsmeow-afk what sorta motors?
22:42 rue_mohr Im thinking of using those 4000N linears
22:43 rue_mohr but leveraging them for speed
22:43 tsmeow-afk looks clue
22:43 rue_mohr http://eds.dyndns.org/~ircjunk/robots/arm4/p1010990.jpg
22:43 tsmeow-afk raises apaw with a question o
22:43 rue_mohr yes?
22:43 katsmeow-afk why not go with hydraulics (water or oil) in an "air muscle" ?
22:44 katsmeow-afk power it fromt ap water
22:44 rue_mohr viscosity
22:44 katsmeow-afk water is pretty thin stuff
22:44 rue_mohr its easier to have a 300psi supply tank of air
22:45 katsmeow-afk and, you have water valves, this cold be a testbed for valve softwre controls
22:45 rue_mohr and air flows thru the valves faster
22:45 katsmeow-afk k
22:45 rue_mohr the valves close alsmost instantly with air
22:45 rue_mohr with water they take up to 2 seconds
22:45 katsmeow-afk true, i was considering the incomprehen,, incompressability of liquids
22:46 katsmeow-afk shame stuff hasto cost,, no matter how cheap one can make valves, 100's of them is gonna cost something
22:46 rue_mohr I must have blown the last test of my fire-course pretty good, I only came out at 97%
22:47 rue_mohr 141 valves total
22:48 rue_mohr (47 are 2 port valves)
22:48 katsmeow-afk you prolly got it solved, but it keeps nagging at me that Rif had trouble with Foxy's allthread "muscles"
22:48 rue_mohr its a learning experiance
22:48 furrywolf if I had to build such a thing, I'd go with hydraulics.
22:49 rue_mohr I'm thinking of making a LARGE pneumatic arm for some extra learning
22:49 rue_mohr this arm I just made was to play with things a bit
22:49 rue_mohr furrywolf, the other thing is that once you get that big, if your system doen't have mechanical give, it will just break
22:49 rue_mohr the airmuscles give nicely
22:49 rue_mohr keeps mechanical stresses down
22:50 rue_mohr there is anothr project
22:50 rue_mohr not by me
22:50 katsmeow-afk i think, unless you're making an amusement park ride, the money is in accuracy more than size
22:50 furrywolf I have an idea that solves roughly every imaginable problem (at least, every problem I've imagined), but don't have the time, money, tools, etc to try it.
22:50 rue_mohr furrywolf, become an artist :)
22:51 rue_mohr people pay lots for art
22:51 rrywolf has no artistic abi
22:51 katsmeow-afk i vote for an "air " muscle with less intrinsic give, and adding a known programmable give to it
22:51 rue_mohr robot? no, its kinematic art
22:52 rue_mohr http://www.anti-robot.com/ <-- thats it
22:52 katsmeow-afk Aunty Robot! Hi!!!!
22:52 furrywolf money is a big problem for me these days. :(
22:52 rue_mohr its hydraulic, but they had to put a pneumatic cylinder in to keep the force down
22:52 rue_mohr furrywolf, art
22:52 rue_mohr find an arts program and build robots with the money
22:53 rue_mohr people wont know the difference
22:53 rue_mohr ^^^ that is funded as an art project
22:53 rue_mohr you tell ME thats art
22:53 katsmeow-afk Tom, can i suggest an avant gard sorta approach to connectors for the next box?
22:54 rue_mohr did anyone check it out?
22:54 furrywolf looks distinctly like it's neither art nor robotics.... 3d graphics, maybe.
22:54 rue_mohr I should post a pic of what they did, its crazy
22:54 furrywolf it doesn't exist yet.
22:54 rue_mohr they have built one leg
22:54 rue_mohr it does exist
22:54 rue_mohr they dont have any pics of it
22:54 rue_mohr but see the videos
22:54 katsmeow-afk sorta resembles a ,,, whachamcallit walker,, and it uses 200hp??
22:55 rue_mohr well, anyhow
22:55 furrywolf are the videos going to need proprietary plugins?
22:55 rue_mohr I can post images if you like that I took
22:55 furrywolf katsmeow-afk: have you seen the john deere walking tree feller-buncher?
22:55 katsmeow-afk theo jansen machine
22:55 katsmeow-afk yeas, i have
22:57 rue_mohr huh I just saw a pic of an electric unicycle on google...
22:58 furrywolf I really wish I had time/money/etc to play with some of my hydraulics ideas.
22:58 katsmeow-afk see the pic of the electric unicycle going sideways?
22:58 furrywolf I think I've solved the problem of working walking robots, but....
22:58 furrywolf practical ones, at least. there's tons of demos and impractical ones.
22:59 katsmeow-afk it's a regular electric unicycle, but they used one of those omniwheels an motorised all the rollers in the wheel
23:03 katsmeow-afk praps i should go look for a nap
23:05 katsmeow-afk zzzzzz
23:08 rue_mohr https://www.youtube.com/watch?feature=endscreen&NR=1&v=Y79p0heTcyY
23:08 rue_mohr katsmeow-afk, there is a good clip of the leg in motion there
23:09 rue_mohr oh I wonder if thers the proffesional camera hat was going around
23:09 rue_mohr if so, I'm in there
23:11 rue_mohr oh it was the guy with the camera in the pvc jig
23:13 rue_mohr good editing job
23:15 rue_mohr https://www.youtube.com/watch?v=dU7ZfqtYFBs&feature=related
23:15 rue_mohr cool
23:18 rue_mohr ah, THEY were the ones with the pro camera
23:21 furrywolf blah, I don't seem to have a suitable heatsink.
23:21 furrywolf only have one cpu cooler here, and the contact area is smaller than the peltier.
23:24 GuShH what the hell http://www.youtube.com/watch?v=bv4a3k-6Z4w
23:27 rue_mohr hahah
23:27 rue_mohr way too much
23:32 GuShH that's a lot of water I got nervous when I saw that.
23:32 GuShH specially after seeing what happens when a modern engine sucks up a mouthful of water.
23:32 GuShH (and having to pay for it)
23:38 rue_mohr it should have been more of a mist
23:38 rue_mohr that much water would pol up
23:41 GuShH you can clearly hear that.
23:42 rue_mohr oops
23:42 rue_mohr I forgot to pick up my solar cell
23:43 rue_mohr hmm I could write that simulator for the rom feedback state machines
23:45 rue_mohr is there anyone left to brainstorm with?
23:48 GuShH http://www.youtube.com/watch?v=KJb5IPOx2l0 this also makes me nervous, this guy is strange.
23:59 rue_mohr computer says I go to bed now
