00:57 zhanx Back pain is keeping me up
01:47 rue_house not knowing where my cats are is keeping me up
08:35 rue_bed i have cats
19:39 any98630565 wiring it taking too much time, and i broke a drill bit
19:39 any98630565 i hope that is valuable info to someone besides me
20:12 any98630565 404 is not found : http://i.imgur.com/EpXBaDQ.jpg
20:13 rue_house hmm
20:14 rue_house hahah 404 not found ahahhahahahaha
20:21 any98630565 have not soldered in weeks, still check iron for presence of hot before touching it
20:22 any98630565 outside.bak
22:00 rue_house why do fuel lines never fail when your down to the last bit of the tank?
22:00 rue_house its always when you decide to trust it and fill it right up
22:02 any62334742 Murphy No such nick/channel
22:03 any62334742 that waterline behind the turbo didn't fail until i poured leak sealant into the radiator
22:03 any62334742 and then it really burst, i could tell where the water was coming from
22:03 any62334742 at idle
22:03 rue_house apparently I blocked all the good isps, all the hack attempts are little pathetic things
22:04 any62334742 i got all the lites secured with bolts, etc, and wired up to the harness on the trailer, so that's done to the tongue, and guess what i found on my way in to get a drink and some #4 thhn?
22:05 any62334742 the pricey waterproof led lites i bought for this task last year
22:05 rue_house good show
22:06 any62334742 you think i am going to rip aparet the work i spent the last 2 days doing, so i can use those precious lites??
22:06 any62334742 hell no, going to get 1157 led "bulbs", solder them in place, and goop it all up with silicone sealant
22:07 any62334742 but if i ever bash up one of th elites, HOPEFULLY then i will remember where i stashed the good led lites
22:08 rue_house oh
22:08 rue_house the lights wont just go in?
22:08 rue_house I'm tired
22:08 rue_house I started tired
22:08 rue_house I got home I was tired
22:09 rue_house I was tired when I got myself to chip some stuff with the chipper and I'm still tired
22:12 any62334742 odd, that should have perked you up
22:14 any62334742 what did you do about the spark plug?
22:15 any62334742 this is what i managed to get for less than 1/2 the current price : http://www.walmart.com/ip/SeaChoice-51901-Led-Trailer-Light-Kit/32739456
22:15 any62334742 but i wasn't going to pay $60 this time
22:15 any62334742 so i put on the best cheap ones i could find , water "resistant"
22:22 rue_shop3 the plug is still held in by the remaining 3 threads on the bottom of the head
22:23 rue_shop3 resistant isn't a good word
22:23 any62334742 stay outa it's aim
22:23 any62334742 yeas, these "resistant" housings have a 1/8 x 1/4 hole in the bottom
22:23 rue_shop3 I was thinking about the natural trajectory accounting for the wire and boot on it
22:24 any62334742 and the possible fireball?
22:24 rue_shop3 I dont beleive in it anymore, I seen the youtube glass cylinder engine
22:24 any62334742 because it may spurt out a cylinder of hot compressed air-gas when it goes
22:25 rue_shop3 I'm gonna have a bigger fireball from the half tank of gas it drained onto the surrounding ground
22:25 any62334742 gas is gonna slow down the plants there too
22:26 rue_shop3 it wrecked some of the chips I'd made
22:26 rue_shop3 I was shredding some light wood for compost
22:27 any62334742 you know wood takes forever to compost, yeas?
22:27 rue_shop3 not this stuff
22:27 rue_shop3 aldar
22:27 any62334742 i mean leave go down in months, wood can take 2 yrs
22:27 rue_shop3 its been sitting 1 year, and is already really soft
22:27 any62334742 oh
22:28 rue_shop3 grows verry fast
22:28 rue_shop3 the ones I planted three years after I got here are already about 50' high
22:29 any62334742 geese, why didn't you send me some to put up tween neighbors?
22:29 rue_shop3 dont you have poplar up there?
22:29 rue_shop3 I thoguht I saw some in the photo
22:30 any62334742 grows slowly, needs full sun
22:30 rue_shop3 s
22:30 rue_shop3 oh
22:30 any62334742 grows real fast from cut stumps tho
22:30 rue_shop3 aldar is as close as you can get to a 'weed tree'
22:31 rue_shop3 wonder how I thought polar grows fast
22:31 rue_shop3 if you cut aldar to the ground every year it really bushes out
22:31 any62334742 it prolly does *in full sun*
22:31 any62334742 plus the ground here is clay, and acid
22:33 rue_shop3 if I have an object that does transformations on values (offset and zero from one array to antoher)
22:33 rue_shop3 and I want to make it store the numbers
22:33 rue_shop3 so I dont have to pass it two arrays
22:34 rue_shop3 should I have it calculate the numbers automatifally when they are written or read?
22:34 any62334742 i don't understand the question'
22:34 rue_shop3 probably requires more background
22:35 rue_shop3 I have a training arm
22:35 rue_shop3 just pots
22:35 rue_shop3 controls the robot arm
22:35 rue_shop3 but all the axies need to be scaled and offset
22:35 rue_shop3 so I made a library, that I give two pointers, one to the orig numbes, and one to a set of results
22:36 rue_shop3 it does the maths
22:36 rue_shop3 but I dont want to have all these storage arrays everywhere
22:36 any62334742 why store the originals?
22:36 rue_shop3 so I'm trying to incorperate them into the functions that do eveyrhting else
22:36 rue_shop3 well, there is one axis thats a problem
22:37 rue_shop3 one of the results has to be the difference of two of the inputs
22:37 rue_shop3 its a kinematic difference
22:37 rue_shop3 and I just realized it comes up more than once
22:38 rue_shop3 *sigh*
22:38 any62334742 a problem generating the original number, or applying t tot he bigger arm?
22:38 rue_shop3 the training arm outputs adc units
22:38 rue_shop3 the arm inputs servo units
22:38 rue_shop3 each system has a different zero and scale
22:38 any62334742 i understand that part
22:39 any62334742 altho you could put apot on the robot too
22:39 rue_shop3 my idea is to translate to an intermediate layer of numbers that reflect a specific pose and are in degrees for units
22:39 rue_shop3 then I can tear the system apart at that point and refit any input system to any output system
22:41 any62334742 ok, a normal decision, i am not understanding the problem
22:41 any62334742 memory space too small?
22:41 rue_shop3 nope
22:41 any62334742 why store the first table at all?
22:41 rue_shop3 I'm keeping the robtos simple
22:41 any62334742 why is the 3rd axis a problem, and for what?
22:41 rue_shop3 I get the input numbesr as a stream of updates
22:42 rue_shop3 6 axies
22:42 rue_shop3 stream from the adc's
22:42 rue_shop3 0-5V as 0-1023 counts
22:42 rue_shop3 the robots take 0-22000 which usually translates to 0-180 degrees
22:43 rue_shop3 but on some of the robots, tilting the wrist will roll it too
22:43 rue_shop3 so you have to run the roll motor when you tilt to stay put
22:44 rue_shop3 but the trainer outputs them independent
22:45 any62334742 erg
22:45 any62334742 to be safe, yu shuod have th same axis in the trainer as in the robot
22:47 rue_shop3 the trainer is technically the one thats right
22:47 rue_shop3 the robots mechanics mix up its motions
22:48 any62334742 it's gonna get as complicated as making two servos emulate steering each front tire separately
22:49 rue_shop3 its just subtraction
22:49 rue_shop3 if (i == 2) {
22:49 rue_shop3 pos = scaleNTranslate((Inputs[2].position - Inputs[1].position), &Transformations[2]);
22:49 rue_shop3 } else {
22:49 rue_shop3 pos = scaleNTranslate(Inputs[i].position, &Transformations[i]);
22:49 rue_shop3 }
22:49 any62334742 oh, then the problem is solve!
22:49 any62334742 d
22:51 rue_shop3 no, I'm making a library to do this all better
22:51 y62334742 needs
22:52 rue_shop3 I'm trying to wrap the trainer into an 'object' and the robot into an 'object'
22:54 e_shop3 hits head on table "I forgot about range lim
22:55 rue_shop3 the numbers arrive in a stream, if two of them need to be cololated, they cant cronologicaly
22:55 rue_shop3 its not simotanious sampling
22:56 rue_shop3 hmm
22:59 any62334742 simultaneous
22:59 any62334742 the "ul" is pronounced
22:59 any62334742 or maybe not
22:59 any62334742 in Canadia
23:00 any62334742 hell, humans here don't even know that word
23:01 rue_shop3 :)
23:01 rue_shop3 my system is based on two arrays
23:02 rue_shop3 for every given output value, you say what the index is of the input value, and what you want to multiply it by and add to it for its result
23:02 rue_shop3 I dont think this idea completely works
23:06 rue_shop3 aaah
23:06 rue_shop3 if the output is initialized to zero
23:06 rue_shop3 and each result it added to the results index
23:06 rue_shop3 nope
23:07 rue_shop3 unless I can specify the index the result it saved to
23:08 rue_shop3 which then lets me do pretty complex things
23:08 rue_shop3 by overlapping result rules
23:08 rue_shop3 so what I build it a list of rules to apply between the two arrays
23:25 rue_shop3 Rule 0: Dst(0) += (Src(0) x 1.00) + 0.00
23:25 rue_shop3 Rule 1: Dst(1) += (Src(1) x 1.00) + 0.00
23:25 rue_shop3 Rule 2: Dst(2) += (Src(2) x 1.00) + 0.00
23:25 rue_shop3 Rule 3: Dst(3) += (Src(4) x 5.00) + 6.00
23:25 rue_shop3 Rule 4: Dst(4) += (Src(4) x 1.00) + 0.00
23:25 rue_shop3 Rule 5: Dst(6) += (Src(5) x 1.00) + 0.00
23:25 rue_shop3 Rule 6: Dst(6) += (Src(6) x 1.00) + 0.00
23:25 rue_shop3 Rule 7: Dst(7) += (Src(7) x 1.00) + 0.00
23:25 rue_shop3 this format will let me do what I want
23:25 rue_shop3 EVEN IF ITS TO TAKE OVER THE WORLD!
23:25 rue_shop3 but its late and I'd better make supper
23:43 y62334742 is bak inside for the
23:44 rue_house I dont know what to make for supper
23:45 rue_house I know I shoud stop trying to use push on gas lines without a retainer fitting
23:45 rue_house today that cost me almost a full tank of gas
23:45 rue_house or half, I really dont know
23:46 rue_house the rule approach solves all my problems
23:51 rue_house and I think it solves problems I havn't had yet
23:51 rue_house BUT IT DOSN'T DAMN WELL EVEN SUGGEST WHAT TO HAVE FOR SUPPER
23:52 any62334742 Campbell serloin stake supe with extra corn and "baked beans"
23:54 rue_house I dont do meat really
23:58 any62334742 ok, spicey veggie
23:58 any62334742 and not cambels,
23:58 any62334742 maybe not even soup
