#robotics Logs

Jul 15 2012

00:00 furrywolf a half hour later, after the cop gives up trying to justify his useless existance (including checking to make sure we weren't drunk... neither of us drink), we finally get to head home.
00:00 GuShH heck new mid range to top of the line cars do it stock.
00:01 furrywolf headlights are only required here when it's dark.
00:01 furrywolf it was just the excuse the cop used to pull us over. he saw a beater truck and was hoping to get it for registration, insurance, etc.
00:02 GuShH beater like this one? http://www.handymanlyness.com/archives/auto/body/repaint/dodge_dakota/blue3.html
00:02 GuShH too bad there aren't close-ups of his work
00:03 furrywolf beater around here means lots of dents, and no attempt at body work.
00:04 furrywolf somehow a bad ground turned into an all evening project.
00:04 GuShH well, to me it means rusted out, banged out, you need-tetanus-shot-to-be-anywhere-near-it :p
00:04 GuShH I kid _a lot_ about the tetanus shots when I see those vehicles.
00:05 furrywolf rust here makes it a rustbucket, not a beater... a beater is specifically "beat to hell", and covered in dents.
00:05 GuShH most people don't care about their cars
00:05 GuShH I won't say most women don't because men are just as likely to abuse them
00:05 GuShH If not maybe worse, but in other ways.
00:06 GuShH furrywolf: what do you call a car that is both covered in dents and rusted out?
00:06 furrywolf a rusty beater.
00:06 GuShH lol
00:06 furrywolf it can be rusted out without being a beater, and it can be a beater with no rust at all... they're terms for different things.
00:06 GuShH I need to deal with rust on the underside of the passenger door, I see a small puddle of rusty water every time I open that door
00:07 GuShH it's somehow collecting there, or dripping from somewhere.
00:07 GuShH -or both-
00:07 furrywolf I've pretty much given up on rust... both my vehicles are on the process to becoming rustbuckets.
00:08 furrywolf a '93 dakota is worth, what, $500? that guy spent waaaay to much work on it.
00:08 GuShH you won't even apply that rust-mort stuff?
00:08 furrywolf useless.
00:08 GuShH it would be worth 5k here. find a way to get those cars here, with their trunks full of scopes --- and you'll be rich
00:09 katsmeow-afk i seem to recall a beater was a truck that people used for beating around in the woods, invariably hitting things stronger than the sheet metal, and denting the truck a lot,,,,, "beating about in the woods" was defined to me as driving like a moron and making noise to find animals to shoot at
00:09 furrywolf katsmeow-afk: that's a woods beater. :)
00:09 katsmeow-afk ah
00:09 GuShH why are such people allowed to own guns?
00:09 furrywolf people in the firewood business, like my friend, usually have a few woods beaters, as getting to the wood involves bashing through the trees...
00:09 GuShH and worst part is they aren't worth the lead you'd need to put them down, let alone all the trouble that comes with it.
00:10 tsmeow-afk goes afk to put the ice cream
00:10 furrywolf meep!
00:11 rrywolf helps katsmeow-afk "put away" the ice c
00:11 GuShH can I have a scoop o' that?
00:12 furrywolf he built a really nice bumper for one of his woods trucks... we called it the V bumper.
00:12 GuShH furrywolf: maybe the dodge was his dad's and he wanted to restore it
00:12 GuShH or maybe he got it for free
00:12 GuShH I'm sure he didn't spend more than 500 bucks on it, if you aren't counting his time
00:13 GuShH also there's the "because I can" factor
00:13 furrywolf it was two pieces of 6" by 4" by 3/8" wall steel tubing, welded together at a right angle, such that the point was 3ft in front of the truck and then two 45 degree angle pieces out to the sides, with lots of braces, then bolted to the frame with big brackets.
00:13 furrywolf like /\
00:13 GuShH are those modifications street legal?
00:13 furrywolf on the front of the truck.
00:13 furrywolf yes
00:14 GuShH interesting.
00:14 GuShH say if you build a custom car from scratch, how do you go about getting it registered, legally speaking?
00:14 furrywolf it was great in the woods... the sides were angled enough that unless you hit a tree dead on with the point, it'd just deflect the truck sideways.
00:14 GuShH here you can't, you have to start from a real, registered chassis
00:14 furrywolf from scratch is a major headache. I don't know the process, but have heard it's very hard.
00:14 GuShH often with an engine block too
00:15 GuShH oh so it's not a local thing, it's an issue in other places as well :(
00:15 furrywolf here the biggest problem is smog. you can drive a rusted out deathtrap with no brakes, but heaven help you if it puts out more than 15ppm hydrocarbons...
00:15 GuShH heh there are some mechanical and emission tests we have to get our vehicles to pass, but they don't seem very strict.
00:16 GuShH and depending on where you live, the cops may never stop you for that.
00:17 GuShH reminds me I need to get a replacement bulb.
00:17 furrywolf that bumper was NICE in the woods... you could just step on the gas and let the truck find its own path...
00:17 furrywolf it'd mow down anything less than 4" thick, and anything thicker would just bump the truck over.
00:17 GuShH kinda like a cow catcher
00:18 GuShH but, repurposed.
00:18 furrywolf we took a bunch of angle iron scraps and welded them vertically on top of this bumper, with a matching shape up at hood level, so it completely protected the whole front of the truck
00:19 katsmeow-afk how did it shove the truck over and not damage the steering?
00:20 furrywolf one night we had to change a tie rod at 3am and 3 miles from the nearest road... :P
00:20 katsmeow-afk and, running over a 4" broken off or bent down tree can make a mess of undercarriage cables and hoses, specially if you stop on one and then back up
00:20 katsmeow-afk ah
00:20 furrywolf although it was from hitting an unseen stump, not being bounced sideways.
00:21 GuShH realistic pessimistic kat strikes again...
00:21 furrywolf heh, we had to patch the radiator up one day, because he did exactly that... backed up after flatting some trees.
00:21 furrywolf it then developed a bunch of 1/4" plate welded across the underside.
00:21 tsmeow-afk
00:22 furrywolf that was a good truck... he finally stopped driving it after the fourth time he rolled it.
00:22 tsmeow-afk cannot explain how she knows
00:23 furrywolf it was amazing... the truck was several inches narrower.
00:23 katsmeow-afk snagging a fence in the knobby tires without knowing it can cause problems soon too
00:23 furrywolf from sliding along so many trees, every bit of the truck had been pushed inwards.
00:23 furrywolf all of the sheetmetal had been pushed against the inner layers, everywhere.
00:24 katsmeow-afk narrower, gets betetr mileage
00:24 furrywolf a half ton of heavy steel, gets worse milage. :)
00:24 furrywolf also, it had a 460. it started out getting 6mpg.
00:25 katsmeow-afk 6mpg oil or gas mileage?
00:26 furrywolf gas
00:26 katsmeow-afk i had a goat that burned half a gallon of oil to work and back
00:26 furrywolf I don't recall it having any oil consumption issues.
00:27 katsmeow-afk i got it used, the guy who owned it rode the hell out of it
00:28 katsmeow-afk this thing had *TORQUE*
00:28 furrywolf I never saw it after the last (fourth) time he rolled it.... said it landed _hard_, bent the frame a foot upwards in the middle.
00:29 katsmeow-afk that's bad on driveshaft alignmnt
00:29 furrywolf yes
00:33 katsmeow-afk U.S. Agriculture Secretary Thomas Vilsack has declared a drought emergency for 33 Alabama counties.
00:34 katsmeow-afk in related news, i have plants sprouting on the roof and my 2000 gallon pool-tank is overfilled
00:38 furrywolf heh
00:38 furrywolf in related news, it's STILL FUCKING RAINING here.
00:39 katsmeow-afk praps you canhire some of those mexican drug tunnel diggers, and pipe that water to the east of the Rockies
00:39 GuShH hmm this is mild damage for a deer hit http://www.bodyshopzone.com/archives/collision/deer_hit/Subaru_2007/front_end.html
00:40 GuShH should've installed one of those V shaped bumpers *nod*
00:40 katsmeow-afk you hear of the latest tunnel? 6ft tall, lots of lectric lites,, what are they sending thru such a tunnel, full grown pot plants that are afraid of the dark?
00:41 GuShH the one that wasn't finished on the US side?
00:41 GuShH drugs, persons, weapons.
00:41 GuShH including fake documents too
00:41 rue_mohr "your just jellous that my half of the fridge takes up more space than your half"
00:41 GuShH you should ask what ISNT smuggled.
00:42 furrywolf the rivers here already have no water in them, from southern california, nevada, etc stealing all of it.
00:42 furrywolf none left to send elsewhere.
00:42 katsmeow-afk shoot, just push a 6" pvc pipe over, and rent a insulation blower from Home Depot, drop in bales of pot and blow them down the pipe at 150mph, prolly faster overall than an 18-wheeler, then take up the pipe
00:42 katsmeow-afk then you know what to do witht he rain?
00:43 ShH informs on katsmeow
00:43 katsmeow-afk (doesn't involve fun peeing)
00:44 furrywolf huh?
00:44 katsmeow-afk ya know, blowing flammable stuff down a 6" pipe with an insulation blower *could* make a hell of a flame thrower, considering silo fires and explosions
00:44 GuShH furrywolf: what the hell is this surge protector they put across the battery (shunt reg?) and why are they talking about damaging currents when it's the voltage that could cause trouble? http://www.bodyshopzone.com/archives/collision/rollover/Jeep_Wrangler_2005/p1/frame_repair_1.html
00:45 GuShH shit I think that's such a load of bullshit, if it were to shunt it would have to be massive.
00:45 GuShH I'd think otherwise if it were in series with the battery and had a contactor inside.
00:46 tsmeow-afk withdraws the observations of new uses for insulation blowers on the grounds of n
00:47 katsmeow-afk explosions, gunfire, and siren noises
00:47 furrywolf it probably contains some MOVs...
00:48 furrywolf as to whether it does anything except lighten someone's wallet, that I doubt.
00:48 katsmeow-afk MOVs?
00:48 furrywolf batteries already make quite good surge protectors.
00:48 GuShH I should start selling those things.
00:48 furrywolf metal oxide varisters
00:48 GuShH crap I think katsmeow-afk still got me on ignore.
00:48 katsmeow-afk oh metal oxide varistors
00:48 GuShH what a resentful person.
00:48 katsmeow-afk i doubt the blowers have any MOVs in them'
00:49 GuShH ignoring someone just makes you look retarded when you don't know what the conversation is all about.
00:49 furrywolf and the computers get damaged by currents induced in the wiring, not by high voltage at the battery terminals. they're already quite well protected against high voltage on the input.
00:49 furrywolf but they're not protected against current being induced in sensor wiring, or having their grounds forced to different levels from the welding current.
00:49 katsmeow-afk and they make 300vdc inside anyhow
00:50 GuShH hmm
00:50 GuShH furrywolf: doubt this thing would have an effect on that
00:50 furrywolf GuShH: exactly
00:51 furrywolf hence why I suspect all it does is lighten people's wallets.
00:51 GuShH like these extra-milage cigarette lighter gadgets, with just an LED inside.
00:51 GuShH but catered to the shop guy.
00:51 furrywolf lol
00:52 GuShH probably costs a small fortune due to the lower demand.
00:52 GuShH they even sell these for homes, I assumed they had a capacitor in them, at least. but I'm not sure.
00:53 furrywolf the whole-house ones are big banks of MOVs.
00:53 GuShH "save cash, spend less in your electrical bill!"
00:53 furrywolf oh, you mean the free energy things, not surge protectors.
00:53 GuShH "hook this thing up, the led will be a clear indicator of your wallet getting thicker!"
00:54 GuShH yes. the only free energy is when you steal from your neighbour.
00:54 GuShH furrywolf: are there MOVs that won't eventually catch on fire yet?
00:55 GuShH Or do you simply deal with it by properly enclosing them
00:56 furrywolf I replaced a surge protecter for someone last thursday that had a big black hole in the side.
00:56 furrywolf so... neither.
01:00 furrywolf heh, looking at some of those body repair articles... they clearly aren't rednecks.
01:00 furrywolf they use a frame machine to pull out body work... a couple years ago, a friend and I were working on a kia with a bad side-impact collision... pushed the B pillar in about six inches.
01:01 furrywolf we didn't have a frame machine. we did, however, have a pickup truck with a big engine and lots of chain...
01:01 katsmeow-afk lol
01:01 furrywolf took about ten good hard yanks to get the new doors to line up properly. :P
01:01 katsmeow-afk i removed a deer impact from the front of a Fairlane with a chain and telephone pole
01:02 furrywolf heh
01:02 katsmeow-afk had the remains of the hood off, so i could see just how far to back up to pull the body front out of the water pump
01:02 furrywolf I've used my little subaru to pull out the front end of THREE different vehicles. yes, three. two ford trucks and a jeep commanche.
01:03 furrywolf all three were mushed bad enough the fan was in the radiator.
01:04 furrywolf by the time we were done with the kia, we'd probably given in 50 yanks with a ford truck... no thanks to a friend of a friend of my friend, who crashed it again while we were in the middle of fixing it.
01:05 katsmeow-afk once replaced a engine mount by gunning the engine in drive, butted against a pole, yanked the old mount out, slipped th enew one in, let the engine down by letting go of the carb linkage
01:05 furrywolf when my friend got it, it only had side impact damage. we got that fixed pretty nicely, then a friend of a friend decided to borrow it while completely drunk, and ran it straight into a stump. crushed the frame horn (well, the unibody equivalent) on one side in about six inches and crumped it under the radiator.
01:05 furrywolf lol
01:05 furrywolf now that's more redneck than anything I've done. I have a hilift for jobs like that. :)
01:06 tsmeow-afk thinks outside the box a
01:07 furrywolf said friend of a friend of a friend was not a friend of either me or my friend, and shouldn't have been driving any of my friend's vehicles... but drunks don't seem to consider things like property ownership.
01:07 katsmeow-afk sure they do! "not mine"
01:08 furrywolf my friend got him to pay for the radiator, headlight, and grille that he smashed, but he wouldn't contibute towards bending it back into shape.
01:09 katsmeow-afk might have run out of money
01:09 furrywolf and he managed to do some mechanical damage too... one cylinder was weak after we recovered it, which it wasn't before, and it could never pass smog. so now with a toasted body and toasted engine, we stopped caring.
01:09 katsmeow-afk i should goto bed
01:10 katsmeow-afk weak, prolly blown head gasket
01:10 furrywolf we gave it to some obnoxious kid that was a relative of some friend, because he'd ended up stranded in california and needed to get back to washington or somewhere up there.
01:10 furrywolf kid was a total ass
01:11 furrywolf he also broke the ignition and some other stuff, so we left some loose wires under the hood you had to tap together to run the starter...
01:12 tsmeow-afk finds some furniture to curl up behind/under and s
01:12 furrywolf we figured having to drive this smashed up car that we'd drug sideways for a mile or so yanking out damaged panels, with bad wiring, a dead cylinder, etc, was a fitting punishment for this kid... he really was an ass.
01:12 furrywolf he was such an ass his parents actually called my friend up and told him to make sure the kid's trip back was as long and unpleasant as possible. lol
01:12 furrywolf they wanted him to stay not-home.
01:13 furrywolf we'd try to get him to help us work on it, and even after we told him we were giving it to him, all he'd do is sit and poke at his cell phone without lifting a finger.
01:14 furrywolf when he refused to help bolt the seats back in (we pulled them for access straightening the b pillar), we gave up, and did the worst work possible.
01:15 rrywolf tucks katsmeow-afk in snugly, then curls up on top of her to make sure she sleeps
01:15 furrywolf I heard the car actually made the trip, after leaving him stranded only a few times and needing to get things fixed...
01:20 rrywolf falls asleep too, it being wolfy bed
02:45 GuShH http://www.wired.com/design/2012/07/10-dollar-robot-challenge/?utm_source=Contextly&utm_medium=RelatedLinks&utm_campaign=Interesting
02:45 GuShH hmm...
02:45 seravitae hi
02:45 GuShH I bet rue_mohr could build a 10 dollar robot
03:23 rue_mohr yea, I'm on it
03:23 rue_mohr I'm at 8.87
03:23 rue_bed its too hot out, and there are too many misquitos
03:25 GuShH rue_bed: build a mosquito hunting robot
03:26 GuShH hi-res camera with motion tracking arm + submachine gun
03:59 seravitae GuShH: there's a TED video of a company that uses a pulsed subsecond laser to blow up mosquitos
04:00 seravitae they even use laser acoustic modelling to determine whether the mosquito is male, or female, or an insect that isnt a mosquito, to chose which to kill.
05:04 GuShH seravitae: and... where can I get one?
06:20 seravitae GuShH: probably have to build your own i'd say
06:20 Modeuse hello
08:06 chris_99 hi, has anyone used check valves before
08:06 chris_99 i'm just wondering if i put 2 in series
08:06 chris_99 if thats equivalent to a double check valve
08:13 seravitae ive used check valves before
08:14 seravitae and yes, using two check valves, one 'before' and one 'after' whatever it is that you're trying to control, works
08:14 seravitae if you mean two check valves directly connected to each other it will operate like a double check valve with a high dead space.
08:46 chris_99 yeah i mean two connected directly to each other seravitae
08:46 chris_99 is a high dead space bad?
08:47 seravitae it will work as you think, mostly
08:47 seravitae high dead space may be bad depending on your application.
08:48 seravitae usualy when volume or flow rate is sensitive through the valves.
08:48 chris_99 ah gotcha, so what does dead space actually mean, the distance between the two valves?
08:53 seravitae dead space is internal volume in the flow path
08:54 chris_99 ah gotcha
08:54 chris_99 thanks for the advice!
08:54 seravitae no problemo
08:54 seravitae if its for some silly robot thing dead space wont be an issue.
08:54 chris_99 it's not actually for a robot thing, it's to connect two beer kegs together :)
08:55 seravitae oh, no problems.
08:55 seravitae why are you doing that?
08:56 chris_99 each keg will have a john guest tap on, then the check valves, and then both connected to the same beer pump
08:56 chris_99 so that i can use the same guinness tap for both kegs basically
08:56 seravitae hm
08:56 seravitae doubling the volume or two seperate beers?
08:56 chris_99 two separate beers
08:57 seravitae and i assume you have a 3-way valve to change lines upstream?
08:57 chris_99 well each keg will have a JG tap so i turn them all off then just turn the right keg on
08:58 chris_99 i didn't know you could get 3-way valves
08:58 seravitae ah yep.
08:58 seravitae not sure if you can get JG 3-ways but we use 3-way mini ball valves, SS316.
08:58 seravitae with barbs/hose nipples, that work under pouring pressure.
08:59 seravitae well i dont personally, i just have a two tap font :P
08:59 seravitae but i know brewers who use em.
09:00 chris_99 aha interesting
09:00 chris_99 do you reckon i could get away with using just one check valve on each keg
09:00 chris_99 to prevent beer mixing
09:00 seravitae yes.
09:01 seravitae i dont know anyone who double checks the JG's
09:01 seravitae double checking usually only provides a slightly better seal by changing pressure differential and providing redundancy
09:01 seravitae you may even get some wierd effect due to the pressure differential between the valves, like outgassing or something strange, but i dont know.
09:02 seravitae anyway one valve is fine.
09:02 chris_99 ooh cool, because they're actually rather expensive �10 per check valve
09:03 seravitae well, if you're brewing to be cheap, you'll save that money in no time brewing your own. if you're brewing because you like quality, then you'll forget about the $10 investment when you start racking up thousands of dollars of grain a year.
09:04 chris_99 i'm brewing because it's fun and yeah i like to make nice beer, so that's a good point
09:04 seravitae i havent even started brewing and i've spent about $3000 so far
09:04 chris_99 eek heh, what kind of setup are you going for?
09:05 seravitae triple 50L vessel single tier HERMS. 6kW HLT, 6kW kettle, 6kW distiller (shhh!), 2kW HERMS, recirculated.
09:06 seravitae quad kegs, keg fridge + controller, co2 tank.
09:06 seravitae plus all the other bits and bobs. plate chiller, PID controller system (developed from scratch by me)
09:06 chris_99 ooh sounds very impressive
09:06 seravitae yeah
09:07 seravitae i actually dont really like beer a lot
09:07 chris_99 haha
09:07 chris_99 are you planning on selling beer then?
09:07 seravitae actually i havent had a beer in about 2 months. actually, im not even allowed to drink beer at the moment.
09:07 seravitae no, i just build building wooshy science looking shit.
09:07 chris_99 heh nice
09:07 chris_99 btw theres a really good homebrew channel on freenode ##homebrew ;)
09:08 seravitae ah nice, ill check it out
09:08 seravitae i actually run/ran a small homebrew business thing
09:08 seravitae i am looking to get the business going again, i had to take a break due to some health problems. im looking at retailing controllers, and scientific gear for brewers.
09:08 chris_99 oh cool :)
09:09 chris_99 USA i guess?
09:09 seravitae australia
09:09 chris_99 aha
09:09 seravitae but i sell wherever people are buying
09:09 chris_99 i'm in the UK, and have just found a few nice malt houses
09:09 seravitae i mostly sell stuff like lab gear, not really grains or anything heavy
09:10 chris_99 what kind of gear?
09:10 seravitae beakers, flasks for culturing / culturing kits, test tube kits for yeast slanting.
09:10 seravitae anything you can buy at a science supply store really
09:11 chris_99 nice, i haven't tried yeast culturing yet, that'll be the next step
09:11 chris_99 i'm contemplating getting a conical fermenter
09:11 seravitae ah yep
09:11 seravitae nobody's really found a good cheap solution yet for those
09:12 chris_99 http://www.oilybits.com/conical-tanks/conical-food-grade-ldpe-polyethylene-tank-220-litre-with-stand/prod_929.html is what i'm looking at
09:12 seravitae ihave some good ideas but im still setting up a workshop and having a play around.
09:12 seravitae yep
09:32 chris_99 what did you do for your HERMS
09:32 chris_99 did you buy an off the shelf thing?
09:34 seravitae nah, im making everything from scratch
09:34 seravitae 2kW 2" BSP immersion element
09:34 seravitae going to get some stainless 3" tubing, thread a cap, shove the element in
09:34 seravitae wind up some copper or thin SS coil
09:35 seravitae temperature sensor in a tee piece on the output
09:35 seravitae me and a friend actually are looking to sell ready made HERMS kits
09:35 chris_99 i don't know much about HERMS, you pump the wort through the copper right?
09:35 seravitae yep
09:35 chris_99 and fill a bucket with water and the 2KW element
09:35 seravitae pretty much.
09:35 chris_99 cool
09:36 chris_99 where are you taking the temperature
09:36 seravitae we acutally built a kickass prototype, unfortunately I havent spoken to my fiend in a while, he went through a divorce and we sorta lost touch.
09:36 seravitae output of the herms
09:36 seravitae there's great debate about whether you should regulate to herms output or tun general temp
09:36 seravitae the argument is invalid when you actually enjoy beer
09:36 seravitae :)
09:37 chris_99 heh
09:37 seravitae anyway i gotta shut my pc off for the night, electrician gotta mess with something tomorrow morning
09:37 seravitae catch ya later
09:37 chris_99 aha, nice speaking to you, toodles

10:23 impulse i think insurance might be a bigger scam
10:48 furrywolf grrrr.... "The fuse was shorted out, due to moisture (or urine, perhaps). So I vacuumed it dry and replaced the fuse. The dim headlight problem was solved." you know, I generally _like_ my fuses to be shorted...
10:48 furrywolf why why why do people call bad connections shorts?
10:48 furrywolf a bad connection is an open, not a short.
10:48 furrywolf this is not complicated.
11:04 theBear anyone ever tried to trigger a pir they don't control ? something like a remote-controlled small heat source ? just wondering how big you have to make it for reliable triggering.. thinking it'd be cool if i could remote-trigger something in my car to turn on the carpark sensorlight at night, maybe even triggered by the motion-detecting security cam software pointed at it
11:04 furrywolf I don't know what the sensitivity range of them is, but I'd try a few cheap IR leds first...
11:05 theBear oooh, you're a thinker... nice work
11:10 Tom_itx ldr with your headlamps hitting it
11:10 Tom_itx when you pull in
11:18 theBear i DON'T control the pir/light... it's gotta be a duress trigger :)
11:19 theBear it already lights when i pull in, but in theory someone smart could approach the car from the other side and at least open the driver door without triggering it
11:19 theBear this is for when i want that camera to have a better look at the car at nighttime
11:29 Tom_itx ahh
11:29 Tom_itx a panic button
11:30 Tom_itx keep it right beside your baseball bat
11:31 theBear heh, now yer on the same page
11:31 Tom_itx just get a cheap motion sensor light
11:32 Tom_itx wire it up to a train horn
11:33 Tom_itx that will scare em off
11:34 theBear yeah, see that's the same reason i can't modify this one, block of flats, in the carpark between all the flats, at nighttime :) i don't think that would fly
11:38 Tom_itx aww, do it just once :)
11:39 theBear hehe, maybe once :)
11:52 rue_bed theBear, yea, a bank of ir leds
11:53 rue_bed wonder if that would work
11:53 Tom_itx rue_bed did you have class yesterday?
11:54 rue_bed yes
11:54 Tom_itx and what did we do?
11:54 rue_bed we fixed the arm, and worked on a design for a rubix solving robot he wants to make
11:54 rue_bed the one we saw online is pneumatic bang-bang
12:04 rue_bed hmm, looks like an overcast day
12:05 rue_bed maybe I better get things under cover
12:05 Tom_itx i wish it would rain here
12:05 ace4016 rained here all last week and now i have mushrooms growing all over my front yard...yay
12:41 furrywolf yay craigslist! just picked up a wheeled trimmer.
12:43 furrywolf http://www.roofmowers.com/piranha.htm
12:44 katsmeow-afk roof mower? i can plant grass on my roof, kool, literally, should be cooler inside
12:44 furrywolf lol
12:45 furrywolf he wanted $175 for it... but he said he could use a 100ft of romex, which he'd trade. so I traded him half of a 200ft roll of romex that I got at a yard sale for $5.
12:45 katsmeow-afk damn
12:45 furrywolf he says it runs... looks like it needs some cleaning, but is overall in good shape.
12:46 katsmeow-afk i hope it runs, you paid $2.50 for it
12:46 furrywolf it's got a kawasaki motor on it...
12:46 katsmeow-afk drat, you need an engine on it
12:47 rrywolf tickles katsmeow-
12:47 katsmeow-afk <giggle>
12:47 tsmeow-afk throws a cluttered up pic of solar rack at f
12:48 furrywolf http://images.craigslist.org/5Ne5I25Kd3K53J13Ncc7e3db7920dfb261013.jpg http://images.craigslist.org/5G95F85Jf3G53m63J8c7e923b3ad1d5601149.jpg http://images.craigslist.org/5L35E95J43L83Jf3H6c7e594adf97059312e5.jpg
12:48 katsmeow-afk ouch
12:49 furrywolf heh, a friend actually put a MOTOR on his rototiller... the gas engine died, so he stuck a 1.5hp electric motor on it... said it worked better than the 5hp gas engine ever did.
12:49 furrywolf ouch?
12:49 katsmeow-afk it's plain he didn't take careof that thing
12:50 furrywolf it's dirty, but it's rust-free, and was indoors.
12:51 furrywolf brb, going to go gas it up and see if it runs.
12:51 katsmeow-afk bring oil
12:51 katsmeow-afk might wanna bring a spark plug socket too
12:51 furrywolf it came with a warning: make sure to turn the fuel shutoff valve off if it'll be sitting for more than a few hours. apparantly the carb floods a bit.
12:52 katsmeow-afk yep, hence : might wanna bring a spark plug socket too
12:52 furrywolf bring? it's in the back of my car. which contains, among other supplies, spark plug sockets and a gallon of oil. :)
12:52 Tom_itx possible plastic float saturated
12:52 katsmeow-afk and if it leaks gas, gas gets past the ring, oil is contaminated, and the engine starts with no oil on the cyl walls
12:52 furrywolf Tom_itx: more likely just crudded up
12:52 katsmeow-afk he didn't take care of it
12:52 furrywolf saturated floats cause a lot more problems than a slight dribble.
12:53 rue_mohr uh, my SSD tanked and took some config files with it
12:53 furrywolf for the price, if I need to clean the carb, I'm not worried. especially since I've found tossing carbs in the ultrasonic cleaner to be a miracle...
12:53 furrywolf you don't even need to take them apart!
12:54 rue_mohr so, I'll be back in a while
12:54 Tom_itx i've done that but usually use berryman chem dip
12:54 katsmeow-afk ssd aren't reliable, noted
12:54 rue_mohr it says its fine, I'm not sure what happened
12:54 rue_mohr fair bit of fs corruption, but, its just the OS drive
12:54 furrywolf I just use ultrasonic cleaner soap... the ultrasonifying (yay, I made up a word) seems very good at breaking loose the gunk crystals gas leaves behind.
12:55 furrywolf fs corruption does not mean a bad drive.
12:55 rue_mohr I have a gui up with *nothing* but a cursor
12:55 katsmeow-afk yeas, and Tiggr filled another 330g hd last nite too, and is in the middle of something i don't wanna stop
12:55 furrywolf unless it tossed up sector read errors or similar, you could have software-caused corruption.
12:55 rue_mohr furrywolf the drive would not read/write ANYTHING by the error messages
12:55 rue_mohr its like it froze up
12:55 Tom_itx rue_mohr what more do you need?
12:55 furrywolf ah
12:55 rue_mohr I keep my data on a raid array
12:56 furrywolf replace the cables
12:56 katsmeow-afk got config on the raid too ?
12:56 furrywolf I've had marginal cables cause the controller to get pissed and stop talking to drives...
12:56 rue_mohr usuauly, I'm gonna update that before I work on fixing
12:56 rue_mohr furrywolf sata?
12:56 furrywolf brb
12:56 katsmeow-afk can you swap out the ssd, and make the os rebuild from memory and hd?
12:57 rue_mohr yes
12:57 katsmeow-afk computers are so primitive at this time
12:58 tsmeow-afk pops off the buttons and grabs a spray silicone bo
12:59 katsmeow-afk this is as freaking advanced as putting vaseline on C cell terminals in the flashlite so they don't corrode and lose contact
13:01 katsmeow-afk bear, ebay has some pir sensors cheap enough to sprinkle around liberally, harborfright has a sale on their pir-activated-leds for $4 sometimes
13:02 katsmeow-afk if you wanna protect the garage, put the pir on garage walls and ceiling (and on the door, pointing down, when the door is up)
13:03 katsmeow-afk to protect the car, put them on the car, so the car has them whereever it is (put pir in the door mirrors, wheelwells, tail and headlites, etc)
13:05 tsmeow-afk knos the bear can prolly think of good places to hide a tiny pir dete
13:06 katsmeow-afk personally too, i'd grid the important parts of the garage with IR led-transistor pairs, they are cheap enough there's hardly a good reason not to, modulated and monitored by an avr, of coursely
13:07 rue_mohr kat, could you google "--get-selections" for me and tell me the command line that option goes with?

13:08 rue_mohr thanks
13:08 katsmeow-afk 131,000 google results
13:09 katsmeow-afk yanno, Tiggr has an interface just for these things
13:09 rue_mohr ok, that worked
13:09 rue_mohr next...
13:09 katsmeow-afk wow, almost 1pm, i should be doing things
13:09 katsmeow-afk yeas?
13:09 furrywolf mower works. carb is dirty, but otherwise it seems perfect.
13:10 katsmeow-afk cool
13:10 furrywolf likes the choke on a bit, and doesn't rev as high as it should.
13:10 katsmeow-afk i'd sell you a mower i have for $2.50, but i'd prolly get more if i separate the metals and scrap it
13:11 katsmeow-afk gummy
13:11 katsmeow-afk has it got an air filter in it?
13:11 furrywolf presumably under all the plastic somewhere.
13:12 katsmeow-afk k, i ran across a Kaw once that would not suck fuel if it had no air filter
13:12 katsmeow-afk idiot picky engine, would also flood instantly if your brother or stepfather over-oiled the sponge air filter (me: why'd you freaking do that?!)
13:12 furrywolf hrmm. sounds like it needed the carb cleaned. :)
13:13 rue_mohr furrywolf open the needle valve a bit more, its starving for fuel
13:13 rue_mohr closing the choke a bit is fixing the air-fuel ratio
13:13 katsmeow-afk we knows
13:13 rue_mohr ok
13:14 furrywolf rue_mohr: more likely, the carb has never been cleaned in the 16 years (motor build date 1996) since it was made, has never been drained or ran dry before storage, and is gummed up.
13:15 katsmeow-afk it had a sponge filter that went in like || , they managed to install it 90 degrees like = , i never before saw a set of males find so many ways to screw up the same one thing for a week
13:15 katsmeow-afk [13:00] <katsmeow-afk> gummy
13:15 katsmeow-afk [12:41] <katsmeow-afk> he didn't take care of it
13:16 furrywolf lol
13:17 katsmeow-afk i came home for a few hrs, pulled the filter, cleaned it in gas, put it in right, the engine fired right up, to show my brother, but before i left, i dunked it in oil and put it back in wrong so i wouldn't get into trouble
13:18 rue_mohr furrywolf oh well yea, its prolly shelacked up, I thought you were taking care of it
13:18 rue_mohr its fun when the float sinks
13:18 rue_mohr thats fun
13:18 katsmeow-afk that had made that poor engine breathe so much oil, the carb was needing more work than when they started working on it
13:18 rrywolf thinks rue's three alter-egos most only be seeing a third of the conversation each, as they missed talking about how easy it is to clean carbs with an ultrasonic cleane
13:19 furrywolf I hate fixing things other people have fixed.
13:19 rue_mohr so fix them yourself in the first place
13:19 katsmeow-afk to be fair, his alter egoes aren't even in the same building
13:19 furrywolf because at least half the time, when they fix a problem, it then has two problems.
13:19 rue_mohr and ones always in bed
13:20 katsmeow-afk yeas, the lazy thing
13:20 katsmeow-afk that one should at least be doing backups and system moitoring
13:20 rue_mohr so, I need to know whats wrong with gnome panel
13:20 katsmeow-afk needs more elfes and trollops
13:20 furrywolf oh, and the mower came with a new pack of replacement strings for it, probably 20 strings.
13:21 katsmeow-afk oh wow, there's some clear dihydrogen oxide falling downthe elevator shaft, brb
13:22 furrywolf got a leak? heh
13:23 katsmeow-afk no, roof dorrs open
13:23 furrywolf ah
13:23 katsmeow-afk the elevator was supposed to gotot he roof deck, the neighbors put an end to that too
13:24 katsmeow-afk so i don't get up tehre to clean the drains, the roof is gonna rot out eventually
13:24 furrywolf from poking at it, I think a carb cleaning is all it needs... I might even be lazy and try a bottle of fuel injector cleaner before tearing it apart, as it's not bad.
13:24 furrywolf oil is only a hair below the full mark and a decent color
13:25 katsmeow-afk it smell good?
13:25 furrywolf which is nice. usually yard sale engines have nothing but some black sludge in the bottom.
13:25 katsmeow-afk he may have changed it yesterday, for the first time
13:25 furrywolf dunno. I don't have much of a sense of smell. (which is a big disability when you're a wolfy!)
13:25 furrywolf no, it's not that light... it looks like it's cut a few lawns since last time it was changed, but it's not ready to be changed yet.
13:26 katsmeow-afk bring the pston down to bottom, turn the crank side to side, see if there's any play in the connectng rod bearings
13:26 furrywolf if it's not clunking, it's good enough. :P
13:26 katsmeow-afk right
13:26 furrywolf it's not like I'm going to rebuild it if I do find play.
13:27 katsmeow-afk yeas, but you could chage to a heavier oil
13:27 furrywolf if the engine goes, I'll toss a nice honda on top.
13:27 furrywolf I like the honda gx series.
13:27 katsmeow-afk the oil pressure on the 280zx dropped at 150,000 miles, the engine was fine, the oil pump was worn out
13:28 katsmeow-afk damn, i need cooler puters or turnt he ac on in this room, it's 90F outside and the temperature is getting over 85F in here
13:29 furrywolf ugh
13:29 furrywolf way too hot for me.
13:30 katsmeow-afk the bottom floor can idle at the average 48hr outside temp, but the puters do add heat
13:30 katsmeow-afk i have not been real aggressive at keeping it cool the last week
13:31 katsmeow-afk the puters should be doing that, but they need interface: servoes, motors, gears, chains, sprockets, sensors, etc
13:31 furrywolf I am uncomfortable over 65F, and useless over 75F.
13:31 katsmeow-afk bedroom with ac is at 75F
13:32 furrywolf too hot to sleep
13:32 katsmeow-afk i should put the baby puter in there, or a laptop, lans are already there
13:32 Tom_itx you sleep in a frig?
13:32 furrywolf Tom_itx: I live in an area where 65F is a very hot day
13:32 katsmeow-afk fan helps, i need it a lil warm, or i get legs cramps bad, i sleep with lectric blanket on high even with ac on'
13:32 Tom_itx alaska?
13:33 katsmeow-afk he lives in a fog
13:33 furrywolf according to my weather station, it went over 65F only twice this month, for very brief periods.
13:33 furrywolf and it's probably biased high with where the sensor is.
13:33 katsmeow-afk but it's a damp 65F, so it's still easy to sweat if you're useful
13:34 Tom_itx last year we had over 50 days of consecutive 100+ F
13:34 furrywolf monthly high was 66.7F
13:34 katsmeow-afk Tom, way past time to "earth shelter" the whole house then
13:35 furrywolf hrmm, looks like it got some garbage in the database when I moved it and had the sensors unplugged... will need to delete that.
13:35 katsmeow-afk just keep on digging out the basement, lower the house a bit at a time
13:35 furrywolf ... and it looks like the wind speed sensor died last week. bleh!
13:36 furrywolf or we haven't had any wind in two weeks, one or the other.
13:36 rrywolf isn't
13:36 furrywolf I'll need to go climb on the roof and poke it.
13:36 katsmeow-afk i have windspeed map covering your area going back several years, furry, if you need them
13:37 furrywolf I'm in a valley, and overall maps aren't too useful, especially for anything shorter than the trees...
13:37 katsmeow-afk put some of that pex up there and give it a calibrated squirt , see if it spins
13:37 furrywolf my measurements have shown I have absolutely no wind power potential.
13:38 tsmeow-afk offers Tom her temperature maps for his
13:39 katsmeow-afk holycrap, lighting hit next door, wrong side to damage the enighbors tho
13:39 hackkitten d'oh~
13:39 katsmeow-afk it's the wierdest thing, after some lighting, the rain stops instantly for a while
13:40 tsmeow-afk meows at hackki

13:42 tsmeow-afk makes motor sounds <purr><puurrrrrr
13:44 katsmeow-afk ok, got 30 sec of lite drizzle, time to water the roof garden before the clouds go away, bbl
13:59 furrywolf bbl
14:12 rue_house this isn't good
14:12 rue_house it looks like all the config files for my gui config are gone
14:19 hackkitten :3
14:19 hackkitten d'aww~
14:21 rue_more interesting
14:22 Tom_itx i thought you didn't run gui
14:22 ckkitten gives rue_mohr a coo
14:23 hackkitten CLI is for real men~
14:24 rue_more hmm, I thought I was using enlightenment, but I wasn't
14:28 rue_more its still got some hints of my old settings
14:30 rue_more I must have been using the gnome window manager
14:32 Tom_itx rue_more
14:32 Tom_itx how old is your SSD?
14:32 rue_more less than a year I'm sure
14:32 Tom_itx using that leveling software?
14:33 Tom_itx i forget what it's called
14:33 rue_more 05/12/11
14:33 Tom_itx i would send it back
14:36 rue_more I still dont know what happened
14:36 Tom_itx i still haven't really put mine to use
14:37 Tom_itx played with it a bit
14:37 rue_more the smart data says its fine
14:41 rue_more I have 10k hours on it
15:17 rue_mohr arg
15:17 rue_mohr I need to tear down x and put it back togethor, like a plugged carb
15:36 rue_shop I hate having to fix a major problem on the computer
16:28 rue_shop taking apart 108 power supplies leaves a person with PILES of the same parts
16:32 tsmeow-afk sends rue her 300 cable b
16:33 katsmeow-afk isn't this why you built that lil robot arm?
19:34 katsmeow-afk About 4 meters (13 feet) off the ground, a catwalk leads through a bizarre landscape of cables, tubes and concrete. This vantage point offers a glimpse into laboratory rooms in which scientists climb around among magnets, electronic equipment, helium tanks and beamlines. Their goal is to explore the realm of antimatter.
19:34 katsmeow-afk i like climbing, maybe i can help explore the realm of antimatter
19:39 tsmeow-afk gets bored spelling mOnOtOnO...... forge
19:43 katsmeow-afk Dirac was completely baffled by Robert Oppenheimer's interest in poetry. "In science," he is quoted as saying, "you want to say something that nobody knew before, in words which everyone can understand. In poetry you are bound to say ... something that everyone knows already in words that nobody can understand."
19:53 katsmeow-afk When he came from Taiwan to the United States, says Ting, he had no more than $100 in his pocket, and yet he managed to have a successful career. As a particle physicist, he later searched in places where no one expected surprises -- and it got him a Nobel Prize in the end.
19:53 katsmeow-afk sounds like someone was pissed
19:59 katsmeow-afk He has just returned from a conference in Ukraine, and he spent the preceding weekend in Tunis, where he brought together young physicists from the northern and southern shores of the Mediterranean. In between, he made a stop in Cambridge
19:59 katsmeow-afk Man he was LOST if he got to Cambridge on his way from Ukraine to Tunis
20:50 katsmeow-afk can i get someone to reprap more of a plastic part if i can supply the part, but no cadcam code for it?
21:29 katsmeow-afk ...
22:28 katsmeow-afk well, that's a dead end
22:42 Tom_itx what plastic part?
22:42 katsmeow-afk http://designerthinking.com/images/%23reprap/m/DSCF2818.jpg
22:42 katsmeow-afk #reprap said no
22:43 Tom_itx did they say why?
22:43 katsmeow-afk i have maybe 30 left, i know a guy may want more
22:43 Tom_itx what is it?
22:43 katsmeow-afk yeas, they said due to stresses the layering will break apart on the alignment pointies

22:45 katsmeow-afk they said afa they knew , no one prints in pvc so that was out too
22:45 Tom_itx i know a guy with a professional machine but i don't know what he charges or whether he would put it in cad
22:45 Tom_itx know of*
22:46 katsmeow-afk to print it, mill it from solid plastic, or injection mold it?
22:46 Tom_itx he has a printer
22:47 katsmeow-afk if it didn't need to be an insulator, i'd be pleased as pie to make it in aluminum
22:47 Tom_itx i don't know what he prints with
22:47 katsmeow-afk not aluminum, that's for sure
22:48 katsmeow-afk theres bits can be left off it, making it a lot easier to make as a plate with things stucking up on one side, which makes it easy to pour or to injecton mold

22:53 katsmeow-afk renting 3D printers, eh?
22:53 Tom_itx it's his i think
22:54 Tom_itx i haven't seen him on irc lately though
22:55 Tom_itx what's it off of?
22:59 GuShH Hmm I didn't know they sold sand-blasting attachments for power washers
22:59 GuShH Anyone ever tried them?
22:59 Tom_itx no
22:59 GuShH The tip has a pickup with a hose that works on suction
23:01 GuShH I'm thinking it could be a good alternative because you wouldn't get massive clouds of media in the air and everywhere around.
23:02 GuShH But I've never seen the results, or figures on whether these are more or less efficient
23:02 GuShH One problem I see is that you couldn't easily recover the media
23:02 GuShH (You can with regular sand-blasting, even though the size gets smaller as you re-use it and you always have to add more...)
23:03 GuShH Come to think of it, the water would actually keep the work piece cool, which is a plus.
23:03 GuShH But in theory it would be less effective.
23:04 GuShH And it may not work with very thin panels at all due to the extra force applied, thanks to the water.
23:04 ShH wonders if furrywolf has anything to
23:40 GuShH rue_mohr: I can't find a list of common CFM use for regular pneumatic tools, namely paint guns on hvlp and hplv
23:41 GuShH average cfm at X psi would be a good starting point, I couldn't find the specifics for every tool I looked at online because the manufacturers were either chinese or the companies had died long ago.
23:58 rue_mohr hmm
23:58 rue_mohr I dont know brands, cant help much
23:59 e_mohr tries to get his gui wor
23:59 katsmeow-afk ok, ro pump is installed, pressure tank is installed, the twain as not connected yet, since the plumbing to the sinks isn't done yet
