12:01 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/sparrow1/p1030525-valvetest.jpg
12:04 AM rue_mohr: !@%$!@#^!@ its worse than that, I breadboarded it
12:04 AM rue_mohr: it really could be anything
12:04 AM rue_mohr: http://ruemohr.org/~ircjunk/robots/sparrow1/p1090946.jpg
12:04 AM rue_mohr: there is my engine pan pattern test
12:04 AM rue_mohr: I just bumped one of the edges by a mm, which should have it
12:04 AM rue_mohr: verry metric
12:04 AM rue_mohr: the right hand area in the middle is the exhaust area
12:04 AM rue_mohr: and the hole on the left is where the shaft goes :)
12:04 AM rue_mohr: rue
12:04 AM rue_mohr: yes?
12:04 AM rue_mohr: humans are all dead
12:04 AM rue_mohr: aaaawweeeee :(((
12:04 AM katsmeow: that's the whole oil pan?
12:04 AM rue_mohr: its not an oil pan
12:06 AM rue_mohr: so I can make the rest of a 3d desgin that seperates the water jacket and the exhaust
12:07 AM rue_mohr: I have to take apart a video of my finger and then put it back togethor
12:12 AM rue_mohr: :) I dont know how I'm gonna model that new applecheesefork
12:12 AM rue_mohr: Tom_L, ?
12:12 AM katsmeow: i doesn't kow
12:12 AM rue_mohr: kat, I do 2.5d modeling, and some shapes are trickey to do that way
12:14 AM katsmeow: ok
12:17 AM rue_mohr: ok I have 240 images to edit
12:17 AM katsmeow: yipes
12:25 AM rue_mohr: oh, that gas bottle
12:25 AM rue_mohr: not fuel, so argon?
12:25 AM rue_mohr: 1200psi
12:26 AM katsmeow: or helium
12:26 AM katsmeow: i dunno how you'd test
12:28 AM rue_mohr: its from the gas place that closed
12:28 AM rue_mohr: I still have an account with the gas producer, who is in vancouver
12:29 AM rue_mohr: not sure the best way to handle it
12:29 AM rue_mohr: its linde, there is a liquid-air handler still
12:30 AM rue_mohr: the motion blur isn't helping
12:45 AM zhanx: so rue_mohr
12:46 AM zhanx: i almost died today
12:46 AM rue_mohr: !??!?!!?
12:47 AM zhanx: car in a curve coming at me lost control and rolled over
12:47 AM zhanx: driver thought he hit me
12:48 AM rue_mohr: did you avoid it?
12:48 AM katsmeow: nope, he died
12:48 AM zhanx: he missed me, i died
12:48 AM rue_mohr: |:/
12:48 AM rue_mohr: hu?
12:49 AM rue_mohr: I presume you meant in your car?
12:49 AM rue_mohr: or were you carless at the time?
12:49 AM zhanx: he was in the ambulance when i left the scene
12:49 AM zhanx: he was
12:49 AM zhanx: i was driving so was he
12:49 AM rue_mohr: k
12:49 AM katsmeow: so you get a free car?
12:49 AM zhanx: nope missed me
12:49 AM rue_mohr: did his car miss your car?
12:49 AM zhanx: his car is fubar
12:50 AM zhanx: i got to cut some airbags to get him out
12:50 AM zhanx: it rolled 2 times and stopped on the drivers side
12:50 AM rue_mohr: slippery road?
12:50 AM rue_mohr: you save him?
12:50 AM zhanx: wet road and he was speeding
12:51 AM zhanx: no he was only hurt a little
12:51 AM zhanx: Troopers said they would call me to update him
12:51 AM katsmeow: seems like he could just toss you the keys then
12:51 AM rue_mohr: do you didn't have to kick the door off and hold an artery closed
12:51 AM zhanx: rue he rolled his little car at 70 mph or so
12:52 AM rue_mohr: wow, thats faster than 70km/h
12:52 AM zhanx: it was snowing and it was 40 mph curve
12:52 AM zhanx: wow math is easy for you
12:52 AM rue_mohr: thank gosh he missed ya
12:53 AM rue_mohr: zhanx, I use a special technique
12:53 AM rue_mohr: you shoot the arrow, then move the target to where it landed
12:53 AM zhanx: he missed me, a truck that was parked waiting on the school bus and telephone poll, 2 bushes
12:53 AM zhanx: lol
12:53 AM rue_mohr: wow
12:53 AM katsmeow: wow, good driver
12:54 AM zhanx: trooper lt said if was going 2 mph slower he would have hit me head on
12:54 AM zhanx: i was like no
12:54 AM zhanx: if i was doing 2 mph slower on my trip, then i would be here in 10 minutes
12:56 AM rue_mohr: why does it take gimp 4 seconds to save a 640x480 pixel image?!?!
12:56 AM zhanx: its gimp
12:57 AM zhanx: it takes 2 secs to decide to do something
12:58 AM rue_mohr: zhanx, well, I'm glad your ok
12:58 AM zhanx: rue_mohr: been a while since i have seen that stuff
12:59 AM zhanx: got the heart moving
12:59 AM rue_mohr: the tank isn't acetelene
12:59 AM rue_mohr: yea, that does
12:59 AM zhanx: i did roll it off the drivers side to the wheels
12:59 AM rue_mohr: :S
01:00 AM zhanx: i was not climb on it
01:01 AM rue_mohr: parse error: temporal context
01:01 AM zhanx: ok i really need to fix this network lag tomorrow
01:01 AM zhanx: i was not going to climb on the car
01:01 AM zhanx: it was easier to push it over
01:01 AM rue_mohr: k
01:03 AM zhanx: i got boots remember?
01:03 AM rue_mohr: mmm
01:05 AM rue_mohr: iiiinteresting
01:05 AM rue_mohr: according to the motion blur, the second segm,ent of a finger from the tip moves more or less linear when curling uncurling
01:07 AM rue_mohr: ok thats 50 images
01:10 AM rue_mohr: last two segments of finger, angles that move togethor aren't the same angle
01:11 AM rue_mohr: knuckle bends more
01:11 AM katsmeow: why limit a robot's movements to what you can do?
01:11 AM rue_mohr: because I need it to do what I do
01:11 AM katsmeow: you'll never stop bullets movingthat slow, or doing that many calculations
01:11 AM rue_mohr: so that I doing it is native
01:11 AM rue_mohr: and I will be the one doing the doing
01:12 AM rue_mohr: I was given some cuda video cards today :)
01:13 AM rue_mohr: I can play with video programming
01:13 AM rue_mohr: gpu programming
01:13 AM katsmeow: good luck
01:13 AM rue_mohr: I was looking at some examples online, its super easy
01:13 AM rue_mohr: getting the environment togethor for doing it may be another matter tho
01:14 AM rue_mohr: tommorow I want to see if I can get the origional air muscle servo going again
01:14 AM rue_mohr: if I can I would like to move it over to stm32
01:15 AM rue_mohr: 74ls595 can be clocked into at like 50Mhz apparently
01:15 AM rue_mohr: so, I can use them for the io breakout to the solinoids
01:15 AM katsmeow: that would be surprising
01:15 AM rue_mohr: each controller would be 8 axies, with 4 valves each, so 32 valves
01:16 AM rue_mohr: and each valve is SLOW, so, all good
01:17 AM rue_mohr: I think a 'tap' on a valve is from about 50ms to 500ms
01:17 AM rue_mohr: and that for small muscles, the big ones will be longer
01:18 AM rue_mohr: if all is good, soon I can get to a doubleacting muscle
01:19 AM rue_mohr: that said, I'm looking at a 3 way balance now
01:19 AM rue_mohr: one thing at a time
01:19 AM rue_mohr: did I tell you about that optimization kat?
01:19 AM katsmeow: no
01:20 AM rue_mohr: take 2 axies, single acting actuators
01:20 AM rue_mohr: you need 1 for pulling A one for counterpulling A
01:20 AM rue_mohr: ditto B, so 4 actuators
01:20 AM rue_mohr: ----
01:20 AM rue_mohr: break it down into 2 axies, X and Y, but use 3 actuators
01:21 AM rue_mohr: the 3 actuators can operate X and Y independently, but with only 3/4 the actuators
01:21 AM katsmeow: i do not see how
01:21 AM rue_mohr: it requires mechanical translation, but its simple
01:22 AM rue_mohr: make independent axies, A and B lie on a puppet control stick
01:22 AM rue_mohr: +
01:22 AM rue_mohr: A
01:22 AM rue_mohr: B B'
01:22 AM rue_mohr: A'
01:23 AM rue_mohr: you can tip the stick to operate A and B independently
01:23 AM rue_mohr: but you can do the same with 3
01:23 AM rue_mohr: I
01:23 AM rue_mohr:
01:23 AM rue_mohr: J K
01:23 AM rue_mohr: see?
01:24 AM rue_mohr: think of it as operating the tilt on a plate, or the puppet cross
01:24 AM katsmeow: no
01:24 AM * katsmeow can wait to see it after you built it
01:24 AM * rue_mohr ditto
01:25 AM rue_mohr: right now I have 47 axies
01:26 AM rue_mohr: at 2 valves ea, thats 188 valves
01:26 AM rue_mohr: if I can pull off this trick
01:26 AM rue_mohr: I can do it with 36 axies
01:26 AM rue_mohr: 144 valves
01:27 AM rue_mohr: wai
01:27 AM rue_mohr: math wrong
01:27 AM rue_mohr: 4 valves per axis
01:27 AM rue_mohr: anyhow, see how this will help my numbers
01:27 AM rue_mohr: ?
01:27 AM rue_mohr: oh I got it right and said it wrong
01:27 AM rue_mohr: whatever
01:29 AM rue_mohr: its saving me finding about 44 valves
01:31 AM rue_mohr: I found 3 last weekend, that was amazing
01:33 AM katsmeow: you may pass on before finding enough
01:34 AM rue_bed: there are about a zillion road blocks, but some of them magicaly dissspear when you walk up to them
01:34 AM rue_bed: if you dont walk up to them, there is no way out
01:34 AM rue_bed: so, I do what I can, and what I can does while I'm doing
01:34 AM rue_bed: it might all work out
01:35 AM katsmeow: umm, ok
01:35 AM rue_bed: if I just sat there and said it was impossable, it would never happen
01:36 AM rue_bed: so far I'v made the pipe bender, got a working airmuscle servo and gathered a lot of materials
01:36 AM rue_bed: and I have the engine
01:36 AM rue_bed: and compressors
01:36 AM katsmeow: but you need to find 144 dead discarded washing machines with good water valves
01:36 AM rue_bed: zhanx,
01:37 AM rue_bed: I need a 600psi air tank
01:37 AM katsmeow: in 20 years of scrounging, i haven;t seen that many
01:37 AM zhanx: k
01:37 AM zhanx: how big?
01:37 AM rue_bed: na, I need 47 washing machine valves and 94 dishwasher valves
01:37 AM rue_bed: not sure, its only a 12' mecha
01:37 AM rue_bed: maybe about 8" x 18"?
01:37 AM zhanx: 400 cfm?
01:38 AM rue_bed: I have two car AC compressors
01:38 AM zhanx: torpedo tank
01:38 AM rue_bed: I presume their good for 600psi
01:38 AM zhanx: no
01:38 AM rue_bed: oh, scuba
01:38 AM rue_bed: damn I have one
01:38 AM zhanx: scuba yes
01:38 AM rue_bed: I use it as a portable air tank
01:38 AM rue_bed: :)))
01:38 AM zhanx: welcome
01:38 AM rue_bed: now re-allocated for the mecha
01:39 AM rue_bed: so, how the hell do I oil the compressors
01:39 AM zhanx: gas
01:39 AM rue_bed: I'm expecting to use a closed loop
01:39 AM zhanx: well let me rephrase that
01:40 AM zhanx: ok closed loop good
01:40 AM rue_bed: but I was going to return the air at limited 10psi, and give it a check to suck fresh in if it needs
01:40 AM zhanx: oh
01:40 AM zhanx: you need an oiler then
01:41 AM rue_bed: I think having more than 10psi on the muscle exhaust ports would be bad
01:41 AM rue_bed: I think the local ice arena uses oilers and seperators
01:41 AM zhanx: that is normal
01:41 AM rue_bed: and recirc the oil to the intake
01:41 AM zhanx: yep
01:41 AM rue_bed: so, ... yea
01:42 AM rue_bed: iirc the AC compressors need oil in their media
01:42 AM zhanx: yes
01:42 AM rue_bed: but I thought they had oil fill plugs in the body too
01:42 AM zhanx: for a/c?
01:42 AM rue_bed: yea
01:42 AM rue_bed: automotive AC
01:43 AM katsmeow: when first charged, they get x amount of freon and y amount of oil
01:43 AM zhanx: no its closed loop with a tev
01:43 AM rue_bed: tev?
01:43 AM katsmeow: oil is circulating witht he freon
01:43 AM rue_bed: yea
01:43 AM zhanx: thermal expansion valve
01:43 AM rue_bed: ok
01:43 AM zhanx: the tev is like a air/water sep
01:43 AM rue_bed: so, I wonder how I do a seperator
01:43 AM katsmeow: zhanx , what happens if too much oil in a large home compressor pot?
01:44 AM zhanx: it fails to cool
01:44 AM katsmeow: rue, same as water seperator on gasoline
01:44 AM rue_bed: what if my robots upsidedown...
01:44 AM katsmeow: failing to cool canbe caused by many otehr things
01:44 AM zhanx: yes but excess oil will always do it
01:44 AM katsmeow: use a centrifigal separator then
01:45 AM katsmeow: :-/
01:45 AM katsmeow: how do i know ther is excess oil?
01:45 AM rue_bed: I have two freezer compressors, should they be able to hit 600psi?
01:46 AM zhanx: by weigh kat
01:46 AM rue_bed: I dont knwo why I chose 600
01:46 AM rue_bed: *take the milk out of the fridge before you weigh it*
01:46 AM zhanx: no
01:46 AM katsmeow: weigh what?
01:46 AM rue_bed: leave the milk in!??
01:46 AM zhanx: using freon as the term which is bad
01:47 AM zhanx: ok freon of a know type at pressure will weigh x
01:47 AM zhanx: the oil will increase the weigh at same pressure
01:47 AM rue_bed: oh 14 tonnes of gas
01:48 AM katsmeow: freon will be in the accumulator at the far end, near the evaporator, how do i know if the compressor's belly is overful of oil?
01:48 AM * rue_bed sleeps
01:49 AM zhanx: hit the charge port with a glove and screw driver, if its all oil
01:49 AM zhanx: you have your answer
01:49 AM zhanx: which is lighter oil or x freon? at room temp
01:49 AM zhanx: charge ports are lower for a reason
01:50 AM katsmeow: i presume fron always is
01:50 AM zhanx: so oil will alway be lower
01:50 AM * katsmeow always added freon to the suction line, whereever it was
01:50 AM zhanx: depends on the system for adding but you are not adding
01:51 AM zhanx: you are checking
12:01 PM Tom_L: https://www.youtube.com/watch?v=kSuaykdvl4I
07:15 PM rue_shop3: waaiiiit a min
07:16 PM rue_shop3: I had a pic
07:16 PM rue_shop3: http://ruemohr.org/~ircjunk/robots/sparrow1/p1030525-valvetest.jpg
07:16 PM rue_shop3: ok
07:17 PM rue_shop3: 2011
07:18 PM * rue_shop3 zooms in
07:18 PM rue_shop3: looks like 4Mhz
11:31 PM rue_mohr: /me listens to the crickets
11:31 PM rue_mohr: <fail>
11:31 PM * katsmeow ponders the sudden removeal of her brains
11:34 PM * rue_mohr wonders where all the good people have gone
11:35 PM rue_mohr: kat, I think I did in one of the pager motors
11:35 PM katsmeow: over current?
11:35 PM rue_mohr: dunno, its not operating quite like it did
11:35 PM katsmeow: well, at least you know now what they are good up until
11:35 PM rue_mohr: they have a lot less torque than I anticipated
11:36 PM katsmeow: they were never designed to DO anything
11:36 PM rue_mohr: arg, my head is all cloudy and I can get anything done on any of the projects
11:37 PM rue_mohr: I'm not entuirely conviced that their not used for camera
11:37 PM rue_mohr: s
11:40 PM zhanx: sorry rue_mohr paperwork
11:40 PM zhanx: done now
11:41 PM rue_mohr: did you make somthing out of paper?
11:41 PM zhanx: i did a custom install today
11:41 PM rue_mohr: I had a dream a long time ago
11:41 PM rue_mohr: I'd converted myself to a machine
11:41 PM rue_mohr: my head wasn't cloudy
11:41 PM rue_mohr: I could think clearly
11:41 PM rue_mohr: and I didn't have to worry about forgetting anything
11:41 PM zhanx: 3600 feet of cat 6 etc
11:41 PM rue_mohr: it was AWESOME
11:41 PM rue_mohr: AND I WANT IT
11:42 PM zhanx: new panel
11:42 PM rue_mohr: not in one data run I hope
11:42 PM zhanx: no
11:42 PM zhanx: but we can try right?
11:42 PM zhanx: 2 fiber runs
11:42 PM rue_mohr: hah, I had someone wanted to go 600'
11:42 PM rue_mohr: I was like NO -> FIBER!
11:42 PM zhanx: couple of 42" touchscreens
11:42 PM rue_mohr: ah
11:43 PM zhanx: 6 story building upgrade
11:43 PM rue_mohr: I think you get about 350' before it stops working
11:43 PM rue_mohr: ah
11:43 PM rue_mohr: thats only 4 boxes wire tho
11:43 PM zhanx: runs up the elevator shaft
11:43 PM rue_mohr: lets see
11:43 PM zhanx: see?
11:44 PM rue_mohr: I recon about 50 man hrs to install
11:44 PM rue_mohr: typically, terminated.
11:44 PM rue_mohr: and tested
11:44 PM zhanx: 9 hours today
11:44 PM zhanx: tested and working one me
11:44 PM zhanx: 2400 bucks
11:44 PM rue_mohr: good show
11:44 PM zhanx: i ran them all at once
11:45 PM rue_mohr: depends on the run types
11:45 PM rue_mohr: but we would run about 4k for that much
11:45 PM zhanx: well each floor had 2 runs
11:45 PM zhanx: well shit
11:45 PM rue_mohr: + material, which is prolly ...
11:45 PM rue_mohr: less panels
11:45 PM zhanx: my profit is 2400
11:46 PM rue_mohr: 1k materials
11:46 PM zhanx: 1.5
11:46 PM rue_mohr: well, a 48p cat6 panel would put my est to more than 1k !
11:46 PM zhanx: touchscreens had a custom base
11:46 PM rue_mohr: yes yes
11:47 PM zhanx: 24p cat 6
11:47 PM rue_mohr: they didn't do a comm room on each floor, riser style?
11:47 PM zhanx: nope
11:47 PM rue_mohr: yea 24p cat 6 ~400 depending
11:47 PM rue_mohr: 48 at 600 or so
11:47 PM rue_mohr: (cad)
11:47 PM zhanx: either way i made a profit, but i guess i could have made more
11:47 PM rue_mohr: we tend to use tyco (amp)
11:48 PM rue_mohr: we charge ~80/hr
11:48 PM zhanx: 80 is my base rate
11:48 PM rue_mohr: I estimate the wire run length and it averages to ~70'/manhr
11:48 PM rue_mohr: we only do continuty tests
11:49 PM zhanx: same here
11:49 PM zhanx: I don't have the 10k tester
11:49 PM rue_mohr: yea, we used to be able to rent one, not anymore
11:49 PM zhanx: i might have the same tester you do
11:49 PM zhanx: fluke?
11:50 PM rue_mohr: iirc yes
11:50 PM zhanx: toner tester?
11:50 PM rue_mohr: er, no
11:50 PM rue_mohr: the one I have is a
11:50 PM zhanx: 1 model up then
11:50 PM rue_mohr: nice one, dont make it anymore
11:50 PM rue_mohr: test-um
11:50 PM zhanx: they dont make mine either
11:50 PM zhanx: now they can charger for a toner and a tester
11:51 PM rue_mohr: the AWESOME thing about it is, that when you plug in the remote end, it automatically turns on, and if the test is good, it beeps,
11:51 PM zhanx: before it was one unit
11:51 PM zhanx: yep
11:51 PM rue_mohr: so I can have a complete idiot help me
11:51 PM zhanx: and i got 6 plugs
11:51 PM rue_mohr: over the phone I can hear the beep, and they dont need to push buttons
11:51 PM zhanx: so i can have the moron plug in 6 at one time
11:51 PM rue_mohr: :)
11:52 PM zhanx: reminds me, need more label maker spools
11:52 PM rue_mohr: its nice not to have to run and up and down 5 flights of stairs/jack
11:52 PM zhanx: i got 2 helpers
11:52 PM rue_mohr: k
11:52 PM zhanx: one that breaths air
11:52 PM zhanx: and one that is a lumberjack
11:53 PM rue_mohr: "what do you means the wire 'broke' ?"
11:53 PM rue_mohr: "just pulled apart!?!?!"
11:53 PM zhanx: the lumberjack has common sense
11:53 PM rue_mohr: good good
11:53 PM zhanx: he may be clueless but has it
11:54 PM zhanx: the kid is plain unhelpable to be honest
11:54 PM rue_mohr: and the other can hold a screwdriver but isn't allowed to try to do anything with it?
11:54 PM zhanx: no he carries things
11:54 PM rue_mohr: yea
11:54 PM zhanx: and complains
11:55 PM rue_mohr: hah
11:55 PM rue_mohr: well good of you to have a crew
11:55 PM zhanx: he was "training" with me today, Cisco router issue
11:55 PM zhanx: why do you need a laptop man its a router
11:55 PM rue_mohr: heh
11:55 PM zhanx: wait what?
11:56 PM zhanx: and this is not his first time seeing it
11:56 PM rue_mohr: knack
