00:02 katsmeow-afk you can move the *entire contents* of a dir to a subdir of the same name tho
00:03 rue_mohr !assist images/foo.png
00:03 tobbor Possibly http://eds.dyndns.org/~ircjunk/images/foo.png
00:03 rue_mohr :)
00:04 rue_mohr see kat, the box was drawn with the new libary
00:04 katsmeow-afk i wa seing that
00:04 rue_mohr with all those commands I can control the servos again
00:04 rue_mohr better than ever now
00:04 katsmeow-afk oh, i know why my tping is so bad lately, my pawsa re clean, sorta, in this difefrent water
00:05 rue_mohr the new protocol means you cant screw up who your getting a reply from
00:05 katsmeow-afk i bet i can!
00:05 rue_mohr and it has lots of room for new commands
00:06 katsmeow-afk 43) do not answer, but tell the otehr servo to answer for you
00:06 rue_mohr anything that gets a reply you have to specifically specify the servo your asking, you cant select a block of servos and ask for them to return a paramiter
00:07 rue_mohr and now I have 'ripple addressing' where you can have the next servo automatically selected after you issue a command
00:07 rue_mohr so if you have to dump new positions to all the servos, its easier
00:07 katsmeow-afk who controls who is the next servo?
00:08 rue_mohr they all track it
00:08 katsmeow-afk 1) ok, 2, you're next
00:08 katsmeow-afk 2) ok 3, you're next
00:08 katsmeow-afk 3) no i am not, we are counting down, 1 is next
00:08 katsmeow-afk 1, you're next
00:08 rue_mohr when you issue a 'one time select' for a servo 512 or greater, they subtract 512 and every command thats issued they all increment the address
00:09 rue_mohr :)
00:09 katsmeow-afk how do they know when to stopt hat and react to real commands
00:10 rue_mohr you can issue a one-time select for servo 1023 which is a magic value, or you can do a global dismiss command
00:10 rue_mohr 0-255 are valid individual servos
00:10 katsmeow-afk o
00:10 katsmeow-afk .. Midnight, start of Friday 5/25/2012 ..
00:11 rue_mohr 256 is a secret phrase for 'all servos' and, in 'one time mode' 512+ is a ripple mode
00:11 rue_mohr so its easy to build a slection of the servos you want to send commands to, and issue the command to them all at once
00:11 katsmeow-afk http://xkcd.com/ misspelled "manufacturer"
00:12 rue_mohr you can even mix latched and one-time selects, and issue a command to a fixed set twice and a subset once...
00:12 rue_mohr weeeeeeeeeeeeeee
00:13 rue_mohr hehe
00:14 katsmeow-afk fuck, to tell them they misspelled, it one must be registered
00:14 rue_mohr just another account
00:14 katsmeow-afk screw it
00:22 e_bed is happy buddy is operational a
00:23 rue_bed esp cause its under control of the onboard now
00:23 rue_bed I'll have to see if I can get one of the onboard serial ports working
00:23 rue_bed not have to use the rs232 converters
00:24 rue_bed I think it can output in ttl levels
00:24 rue_bed now I can start wiring in the overload boards
00:28 rue_bed I think I was writing a communications thread manager, but I cant find that code either
00:29 rue_bed I think thats why I did the protocol rewite, cause when I was making communications manager I realized there were collisions and inefficiencies all over the place
00:29 rue_bed I wonder if I can find it in the logs
00:42 katsmeow-afk ......
01:30 tsmeow-afk goes away
06:46 Sunnyday woo
08:06 Silanik I want to measure the response/reaction time of humans for my project. I want a setup like, when light indicator turns on you punch a pad (where a simple sensor is attached only to sense the punch) and feed the response time to a computer to generate a graph. I am a Mechanical Eng. student, Can somebody please give me a simple 'How to do' and some references so I can do this by myself.
08:08 Triffid_Hunter Silanik: sounds like an ideal candidate for your very first arduino project ;)
08:09 Triffid_Hunter for extra points, use the chip's hardware timer capture feature
08:09 Silanik Oh thanks Triffid_Hunter
08:10 Silanik Triffid_Hunter: I am from a small town in India. I can't afford buying an Arduino. Can I do it by other means.
08:23 Triffid_Hunter Silanik: sure, change something onscreen, time how long it takes the user to press a key on the keyboard
08:38 Silanik That's a good Idea Triffid_Hunter
08:38 Silanik Thanks
09:10 rue_mohr somehow I suspect that they may have parallel ports they can work with
09:11 Steffanx rue_mohr and this parallel ports :)
09:13 rue_mohr so 3 of buddys 18 axies are a bit unstable
09:13 rue_mohr sit there hunting
09:14 rue_mohr I suppose my next revisions need to let me adjust the integrator
09:30 rue_mohr off to work!
11:42 skavyouz hey, i have a project for a stereo system, the vehicle I was working on didn't have a 12v signal enabler, so I used the 12v rail from the
11:42 skavyouz battery with a switch to control the relay to turn the radio on and off
11:44 skavyouz I can't go able 30 volume, and as time goes on max setting lowers and lowers, we pulled the thing out and the back was burning hot on touch
11:44 skavyouz i assumed the relay was getting too high of a amperage, so i placed a 27K 1/4W resistor
11:45 skavyouz between the 12V and switch
11:45 skavyouz 27K is as high of a resistance I can go
11:46 skavyouz before it doesn't turn on, 33k is too high, and it doesn't turn on. two 56k in parrellel also has this functioning,
11:46 skavyouz it doesn't heat up as fast,
11:46 skavyouz but still heats up
11:46 skavyouz any ideas?
11:53 skavyouz hey slide know alot about electronics?
11:57 skavyouz aquilae know alot a
11:58 skavyouz about electronics?
11:58 Aquilae not really
11:58 Aquilae soz
11:58 skavyouz oky
14:20 katsmeow-afk a 27k resistor at 12v is only 0.005 watts, i am trying to figure out how you think that is making the radio too hot to touch
15:36 home i got an l293D and a comparator
15:36 home what does a comparator
15:37 home hmm got an l293D bridge.. and a motor stripped from a drill
15:37 Tom_itx the bridge is likely not big enough
15:38 Tom_itx 1A ?
15:38 home not sure
15:38 Tom_itx if you stall the motor and the lid pops off of the chip you'll know it wasn
15:38 Tom_itx 't
16:24 katsmeow-afk it's one of those "poppy lid" chips?
16:34 tsmeow-afk expects to see an ebay auction for one "this rare chip dates back to when there were no electronics, and protection circuits were purely mechanical,,, this one pops the lid to relieve pressure when it gets too
17:36 katsmeow-afk chip refurbish service: chip re-lidding , if your chip popped it's top to relieve pressure or overcrowding, let us place a whole new lid on the chip and clean it up to oem specifications. This even applies to chips you have programmed, altho "oem specifications" means "prior to you programming it". This service is available for only $5usd per chip for common chips, which we keep lids for in our stock at all times.
17:43 iR0b0t1 It's funny, because you just sell them a new chip.
18:23 katsmeow-afk well, cops here have been busy: one arrested for serial arson (burning lots of houses down), one for child porn (pics and engaging in), and cops in one town arrested someone on a *civil* charge of non-payment of a bill and applied his bail to the late fees and gave him the remainder back and let him go (illegal arrest, incarceration, and misappropriation of money)
19:28 katsmeow-afk "12 Alabama children sickened by detergent packets" <<== parents transfer burden of controlling their child onto the detergent companies , seriously
19:28 rue_mohr nap time
19:29 katsmeow-afk <parent> who knew a toddler would eat something that looks like candy?
19:34 gartt katsmeow-afk: We just need more warning labels on everything! And on trees in the woods in case people run into them or branches fall on people
19:34 katsmeow-afk children have been known to eat keys, all oem that force parents to use a key should be sued
19:35 gartt The scariest one is when kids swallow strong magnets
19:35 katsmeow-afk children have been known to eat coins, all stores that force parents to use coins should be sued
19:35 gartt One's fine, but more than one at different time intervals, and it keeps the intestine "kinked" around itself and you have to open the kid up
19:36 gartt katsmeow-afk: Now you're getting it!
19:36 gartt Just sue whenever there's no warning label or waiver
19:37 katsmeow-afk saw a video of a dog that hates cleaning supplies, and he bit into and punctured a spray can of paint, filling his mouth and lungs with paint, and spraying the kitchen,, and then the spray can propellant hit the stove pilot light and blew up the kitchen,,,, none of this is the dog's fault
19:37 gartt And we need to remove any sculptures or paintings with nudity in them from our museums for the children
19:37 katsmeow-afk astonishing
19:37 gartt It's entirely the dog's fault. Obviously he had the demon in him
19:38 gartt Quite a coincidence though
19:38 katsmeow-afk conincidence?
19:38 gartt When the spray can propellant hit the stove pilot light
19:39 katsmeow-afk right, owner chose a stove with constant pilot light, kept flammable spray paint in the kitchen, owned a dog that would attack these things, and placed the things wehre the dog can get at them,, and then at that time OPENED THE CABINET DOOR WITH THE DOG RIGHT THERE, UNRESTRAINED
19:40 katsmeow-afk i am pretty sure there were warning stickers on everything but the dog
19:41 gartt Well, that's why dogs need to come with more warning labels
19:41 katsmeow-afk why? the owner ignored all those on the other items
19:41 gartt Well, can't the dog be sued?
19:41 katsmeow-afk "this is my god, it can do no harm, i won't be reading it's warning labels"
19:41 katsmeow-afk nope, gods canot be sued
19:42 gartt How about god's best friend?
19:42 katsmeow-afk think i can catch the neighbor's god and put a hermetically shrinkwrapped warning label on it?
19:43 gartt katsmeow-afk: I think you're onto something
19:44 katsmeow-afk i'm sorry, when i got it, the god had no warning label about putting the god into an hermetically shrinked wrapped warning label
19:49 gartt I'm completely out of the loop, but how's the trimaran going?
19:50 katsmeow-afk had to leave part of it in Fla, and the turning jig, along with both cat hulls, and some other steel
19:51 katsmeow-afk i am broke and facing bankruptcy over that attempted move
19:51 gartt Oh. I was just curious because it was an interesting project
19:52 katsmeow-afk yeas, i would have been only a couple miles from the St John's river there too,, and the whole thing became a fiasco
19:53 gartt Stuff happens - lots of variables
19:53 gartt It's just cool that you built so much of it
19:54 katsmeow-afk yea
21:42 Tom_itx http://www.cyrom.org/palbum/main.php?g2_itemId=5168&g2_imageViewsIndex=1
21:52 katsmeow-afk a cautionary pic about turning on your quadcopter and it blowing all the hot ashes out of the bbq grill?
21:54 m_itx
21:55 katsmeow-afk they didn't learn a whole lot by that crash, http://www.cyrom.org/palbum/main.php?g2_itemId=5204 still has a base that's too small for real stability on landing
21:55 katsmeow-afk in crosswinds, things can get tilty in a real hurry
21:55 rue_bed kat, you should sue him for that, I'm sure you have grounds you can win
21:56 rue_bed in the usa you can sue someone for anyhting and win
21:56 rue_bed you could prolly use the fact there was no toilet
21:57 rue_bed you just have to pick one thing
21:57 katsmeow-afk well, but finally someone did loose: a woman was acquitted of causing a wreck , she was not in the vehicle, not on that side of town, and did not force her bf to read her text msg
21:57 rue_bed that he's definitly guilty of
21:58 katsmeow-afk the jury decided he turned the phone on and he quit watching where he was going so he could read the msg
21:59 katsmeow-afk kool, a battery powered trailer just the right size for your mowerbot : http://www.cyrom.org/palbum/main.php?g2_itemId=6235
22:00 katsmeow-afk mowerbot can drag it around without using any of it's own batery power
22:00 rue_bed the new mowerbot is built form a platform capable of transporting the average USA fat person, its good for quite a bit of battery
22:01 katsmeow-afk that would be quite a feat of engineering
22:01 katsmeow-afk is it too heavy to mow the yard now?
22:01 rue_bed no
22:01 rue_bed there is no usa fat person installed
22:02 tsmeow-afk imaines real railroad wheels under it, sinking into the ground 4 inches everywhere it
22:02 rue_bed I want a cookie and I cant have one :(
22:04 Tom_itx i wanna work on the mill but i'm still tired and it's hot out there
22:04 katsmeow-afk http://www.cyrom.org/palbum/main.php?g2_itemId=4307
22:04 rue_bed I just woke up
22:04 Tom_itx i tried but couldn't
22:04 rue_bed and I'm already sentient
22:05 katsmeow-afk remarkable
22:06 katsmeow-afk where is "out there" ?
22:06 Tom_itx garage
22:07 katsmeow-afk open window, toss it out so it's under the roof you added on a couple yrs ago
22:07 katsmeow-afk it's cooler out tehre
22:07 Tom_itx way too much effort
22:07 katsmeow-afk add conveyor belt out the window?
22:07 katsmeow-afk overhead bridge crane :-)
22:07 Tom_itx i'd have to move the mill, the new controller, the pc etc
22:08 katsmeow-afk oh, easier to open the garage doors you installed on all 4 walls
22:08 katsmeow-afk my nukebox just bleated, dinner is ready
22:25 katsmeow-afk how to make pasta taste pricey : butterit when still superhot, then stir in a sprinkle of McCormick herb&wine basting/marinade spice powder, add a dash of allspice and tumeric
22:26 katsmeow-afk turmeric
22:27 katsmeow-afk Turmeric (Curcuma longa) is a rhizomatous herbaceous plant of the Zingiberaceae family
22:28 Tom_itx you could talk all day about it and i'd still be ignorant on it :)
22:29 katsmeow-afk you don't need the allspice and tumeric, i am just trying them together the last week, and they are good, in just a very light dusting once and then stirred in completely
22:29 katsmeow-afk the McCormick herb&wine is the significant flavoring
22:29 katsmeow-afk they make others, but i don't like them as much, they seem to be lacking something
22:31 katsmeow-afk The government of Thailand is funding a project to extract and isolate tetrahydrocurcuminoids (THC) from turmeric. which isn't the same THC i grew up with in high school
22:32 katsmeow-afk http://clinicaltrials.gov/ct2/results?term=curcumin
22:34 katsmeow-afk Evidence exists to support low-grade inflammation as the inciting factor leading to visceral hypersensitivity and alteration in motility in irritable bowel syndrome.In the medical literature,there is ample in vitro and in vivo evidence supporting turmeric and its derivative curcumin as an antitumor, anti-inflammatory and antioxidant agent.
22:35 katsmeow-afk they don't give the results of the trial :-/
22:35 Tom_itx maybe it wasn't in their favor
22:37 katsmeow-afk Curcumin induces autophagy to protect vascular endothelial cell survival from oxidative stress damage.
22:38 katsmeow-afk this would be great : Curcumin-induced apoptosis in human hepatocellular carcinoma j5 cells: critical role of ca(+2)-dependent pathway.
22:40 katsmeow-afk anyhow, it's good for you, and it tastes good too!
22:41 katsmeow-afk might be a cure, or partial cure, or prophlactic, against Helicobacter pylori
22:41 katsmeow-afk it's what i am thinking
22:42 Tom_itx yeah
22:42 Tom_itx btw i'm not ignoring.. just barely awake
22:42 katsmeow-afk i should be doing plumbing
22:43 katsmeow-afk it's all laid out, all i need to it glue/screw/bolt it to the wall
22:44 katsmeow-afk till i can get the rest of the RO done, i'll just set a timer to check it refilling gallon jugs, should be tween 30 min and 60 min per jug while i watch news or irc
22:47 ace4016 kats, they've been finding a lot of conditions and such are caused by inflammatory responses and messing around with hormones...
23:03 tsmeow-afk
23:04 katsmeow-afk tiredness, for one
23:05 katsmeow-afk a bad tooth, from what i can tell, can throw one way off, and not be noticed as a bad tooth
23:05 katsmeow-afk ditto sinus infection
23:07 katsmeow-afk does anyone here need a 5kva (5kw) transformer, 480-240 in, 240-120 out ? or vice versa?
23:11 tsmeow-afk goes back to sniffing pvc
