12:11 AM rue_shop3: I'm 94 hours into my vaccation
12:14 AM rue_shop3: anniepoo_, your alive, right?
01:11 AM rue_shop3: "We dont have a 2.anything k resistor?" "oh, here we go" "what is it?" "2.purple K"
01:35 AM Luminax-Work is now known as LuminaxWk
02:11 AM anonnumberanon: rue_shop3, no my first crash the plane just went up really fast and did a loop and came down crashing
02:11 AM anonnumberanon: this time around it was making circles around me very fast
02:13 AM rue_shop3: ah, so we have defined classes of 'out of control
02:13 AM rue_shop3: ;
02:13 AM rue_shop3: '
02:13 AM rue_shop3: 'lsadf;ks;f
02:14 AM rue_shop3: my head hurts
02:14 AM rue_shop3: I dont think I can take 100% me
02:14 AM rue_shop3: NO I CANT TAKE 100% ME
02:14 AM * rue_shop3 runs in circles screaming
02:16 AM rue_shop3: and it seems like 90% of the time I'm the only one on the internet
02:16 AM rue_shop3: it seems that there are two distinct periods where people dont use the internet
02:16 AM rue_shop3: during the day, and at night
02:20 AM anonnumberanon: never, EVER get an airplane without ailerons
02:20 AM rue_shop3: hahahahahaha
02:20 AM rue_shop3: thought you said never get on one
02:21 AM anonnumberanon: i don't know about real airplanes, I'll compress the topic to RC for now
02:23 AM anonnumberanon: some delta wings, dunno if have ailerons
02:23 AM anonnumberanon: but I'd still pilot the heck out of those jet fighters
02:27 AM rue_shop3: I'm starting to think that engine is better off on a shelf
02:27 AM rue_shop3: does it have some compression if you give it a twist by hand?
02:27 AM rue_shop3: is it seized?
02:28 AM rue_shop3: zhanx, wtf, did you make those 4 little wood blocks?
02:29 AM rue_shop3: by now I could have trained woodlice, put them in a box with 4 pieces of wood, shipped them, and you would have the parts there already made.
02:30 AM rue_shop3: UGH
02:30 AM rue_shop3: I created two arrays, I should have combined them
02:31 AM anonnumberanon: yeah it has compression
02:31 AM rue_shop3: ok
02:31 AM rue_shop3: take a multimeter and see if there is still a coil on the plug
02:31 AM rue_shop3: the resistance from the tip of the plug to the case should be about 0 ohms
02:31 AM rue_shop3: +- an ohm
02:31 AM anonnumberanon: probably cause it's new from last year
02:31 AM anonnumberanon: but i'll check sure
02:32 AM rue_shop3: do you have a compressed air line?
02:32 AM anonnumberanon: nerp
02:32 AM rue_shop3: air spray nozel?
02:32 AM rue_shop3: no, hmm
02:32 AM rue_shop3: well see how the plugs doing
02:33 AM anonnumberanon: what if it's fine
02:33 AM rue_shop3: then we keep going down the list :)
02:33 AM anonnumberanon: k ill check it tomorrow
02:34 AM anonnumberanon: multimeter is in the car and anonnumberanon is in the bed
02:34 AM rue_shop3: WTF!
02:34 AM rue_shop3: you dont have a multimeter in your bed!!?!?!?!
02:34 AM anonnumberanon: damn
02:34 AM anonnumberanon: nobody's perfect
02:34 AM rue_shop3: suppose you dont have a screwdriver set either!?
02:35 AM rue_shop3: what if one night the bed is squeeking and its keeping you up?
02:35 AM rue_shop3: what you gonna do then!?
02:35 AM rue_shop3: ugh....
02:35 AM anonnumberanon: my tools are pretty much spread out in the garage and the trunk of my car
02:35 AM anonnumberanon: i don't keep tools in my room
02:35 AM anonnumberanon: rule number 1
02:35 AM rue_shop3: the GARAGE!, you ... you...
02:36 AM rue_shop3: YOU SLEEP IN YOUR BED AND MAKE THE TOOLS STAY OUT IN THE GARAGE!?
02:36 AM rue_shop3: how would you like it if THEY did that to YOU!?
02:37 AM anonnumberanon: they leave me in my room a lot, I don't complain
02:38 AM rue_shop3: oooh, my brain is shutting down on me
02:39 AM rue_shop3: its only midnight, damnit
02:39 AM anonnumberanon: 5 5 1 2 3 4 5 1 7 3 4 5
02:39 AM anonnumberanon: Length of LCS is 4
02:39 AM anonnumberanon: 1 2 3 4 5
02:39 AM anonnumberanon: 1 1 1
02:39 AM anonnumberanon: 7 1 1
02:39 AM anonnumberanon: 3 2
02:39 AM anonnumberanon: 4 3
02:39 AM anonnumberanon: 5 4
02:40 AM rue_shop3: no, its the reset pulse screwing me over
02:41 AM rue_shop3: I think I got it tho
02:41 AM anonnumberanon: now i computed this but how to get back " 1345" from it
02:42 AM rue_shop3: this logic analizer, makes nice quick and dirty scope for this stuff
02:43 AM rue_shop3: I like a scope with a digital zoom :)
02:43 AM anonnumberanon: i can see the electrons with mine
02:44 AM rue_shop3: do you think 0.25uS is long enough to reset a CD4017?
02:45 AM rue_shop3: !bookmark
02:46 AM rue_shop3: ok, my new shop needs a) dumping zone b) sorting area c) storage area for sorted stuff d) tools area e) clear, open workspace
02:46 AM rue_shop3: oh and chill area
02:49 AM rue_shop3: hahah, I"m so tired I was gonna look at hte datasheet for hte 4017 to see where ground is
02:51 AM anonnumberanon: i know the feeling
02:51 AM rue_shop3: I built a datasheet book
02:51 AM rue_shop3: quite liking it
02:52 AM anonnumberanon: got to understand LCS more to own it and vinquish these hackerrank challenges but brain is boiled now
02:52 AM anonnumberanon: so just staring at computer screen
02:52 AM anonnumberanon: and wasting keystrokes in #robotics
02:52 AM rue_shop3: hacker challanges?
02:53 AM anonnumberanon: it's a website to solve programming challenges for fun
02:53 AM anonnumberanon: but this challenge was very tough
02:54 AM rue_shop3: alg or hardware stuff?
02:54 AM anonnumberanon: yeah algorithms
02:54 AM anonnumberanon: well just CS in general
02:54 AM rue_shop3: is it a state machine or logic table?
02:54 AM anonnumberanon: cause it has "algorithms", "data structures", "sorting", security, etc
02:54 AM rue_shop3: ah
02:55 AM anonnumberanon: it's a lookup table actually
02:56 AM anonnumberanon: but dynamically generated, not like what you'd do on a microcontroller at startup to save computing speed while running math stuff
02:56 AM anonnumberanon: if that makes rigorous nonsense enough
02:57 AM rue_shop3: oh that idea interested me for the AI stuff
02:57 AM rue_shop3: so I went on a week long thought process on modifying the table
02:57 AM rue_shop3: and realized how human learning works
02:57 AM rue_shop3: which resulted in another "is that all we are?"
02:58 AM anonnumberanon: no obviously there is a god
02:58 AM anonnumberanon: meet him/them at Rama
02:59 AM rue_shop3: I'm not as good as I'd like t be at seeing fractal structures, but I can see them in how people work, just a bit
03:01 AM rue_shop3: hah I think this is working
03:07 AM rue_shop3: oh yea
03:07 AM rue_shop3: :) I'v got a m328 doing a 16 channel controller with a 31000 count resolution
03:08 AM rue_shop3: bit more cleanup required
03:12 AM anonnumberanon: damn okay i found the solution to finish my program, this is my queue to sleep on it and read it in the morning, the most painful is done, finding, then the fun part, understanding !
03:13 AM rue_shop3: oh I'v got a mess
03:13 AM rue_shop3: I have to drink on this for a bit...
03:13 AM anonnumberanon: cool to hear about that servo controller almost running, i d like to see the result!
03:13 AM anonnumberanon: bed now
03:18 AM rue_shop3: oo idea
03:18 AM rue_shop3: a cup storage device that automatically refills it as req'd
03:28 AM SpeedEvil: ITYM a maid.
03:28 AM rue_shop3: no, like alittle coffee machine
03:28 AM rue_shop3: you put the cup back in it every time, and it just keeps you topped up
03:29 AM SpeedEvil: That seems like a terrible idea to get stale coffee
03:29 AM rue_shop3: good thing I dont drink coffee
03:30 AM Jak_o_Shadows: rue_shop3 yeah. That iws waht I bought it for
03:31 AM rue_shop3: sorry, forgot the qutestion
03:32 AM Luminax-Work is now known as LuminaxWk
03:32 AM rue_shop3: ok, I have a 16 channel controller but honestly, ... no idea what I'd use it for
03:39 AM rue_shop3: "yes I'd like to complain about this mousepad" "yes, what the compaint" "the cusror skips around" "what part of the mousepad are you on when this happens?" "It happens when the mouse is moved off the pad"
03:42 AM rue_shop3: oh, the limit is 24000
03:42 AM rue_shop3: not 31000, sorry
03:43 AM rue_shop3: ok, thats the code
03:46 AM Jak_o_Shadows: panel mount usb
03:46 AM rue_shop3: oh
03:46 AM rue_shop3: did you see the thingiverse one I did?
03:46 AM Jak_o_Shadows: Yeah, I have one of those. But like, I was going to use it to embed a serial adaptor
03:46 AM Jak_o_Shadows: yeah
03:46 AM Jak_o_Shadows: I bought one with panel mount holes :D
03:47 AM Jak_o_Shadows: but that means I need to connect a male plug to a male plug on the computer
03:47 AM rue_shop3: ... thats the peice I made
03:47 AM rue_shop3: with mine you just use an AB cord to whatever your operating
03:47 AM Jak_o_Shadows: ah!!!!!!!!
03:47 AM Jak_o_Shadows: You bought an AB
03:47 AM Jak_o_Shadows: I bought AA
03:47 AM Jak_o_Shadows: yup
03:47 AM Jak_o_Shadows: gotcha
03:48 AM rue_shop3: http://ruemohr.org/~ircjunk/projects/screwsorter/p1090146.jpg
03:48 AM rue_shop3: sorry, I didn't update the pics, but you can kinda see there
03:49 AM rue_shop3: I plug a usb<->ttl adapter
03:49 AM rue_shop3: with that 3d printed bit it all just hangs on the back of the case
03:50 AM Jak_o_Shadows: yeah.
03:50 AM rue_shop3: ugh, I didn't take any images from the cnc either
03:50 AM Jak_o_Shadows: I should have bought female USB A B, not A A
03:51 AM rue_shop3: dont ahve images of it on my tilt-n-pan mirror either
03:52 AM rue_shop3: I'll test this code for the 4017's running on the avr
03:52 AM Jak_o_Shadows: I guess I'm set if I ever make any usb host devices though
03:52 AM rue_shop3: then port it over to the stm32
03:52 AM Jak_o_Shadows: apparently the stm32's can do usb host.
03:52 AM rue_shop3: (which means rewriting it, cause nothing ports)
03:54 AM Jak_o_Shadows: yeah.
03:54 AM Jak_o_Shadows: If nothing ports, I like things to be a thin layer over the hardware at least
03:54 AM rue_shop3: but I can do 4 channels on the stm32
03:54 AM rue_shop3: which means up to 32 servos
03:55 AM rue_shop3: but I have a problem in the meantime
03:55 AM rue_shop3: I dont have any software to test the protocol this uses
03:55 AM rue_shop3: not manualy operable anyhow
03:55 AM rue_shop3: if I was better at ui stuff, I'm sure I could make a program with 32 sliders
03:56 AM rue_shop3: maybe today is a good day to die
03:56 AM rue_shop3: er, I mean,
03:56 AM rue_shop3: learn to program that
03:56 AM rue_shop3: its 1:30am now
03:57 AM rue_shop3: then what you gonna do rue, make a 16 channel servo controller for the shelf!?
03:57 AM rue_shop3: hmm, I suppose I'd have to make something to really test it
03:57 AM rue_shop3: but... for the shelf?
03:57 AM rue_shop3: well, not ideally no
03:57 AM rue_shop3: so move on to the stm32
03:57 AM rue_shop3: but we dont know if this works right
03:59 AM rue_shop3: this code has 1 non-compliance
03:59 AM rue_shop3: and thats that it dosn't use a 20ms cycle time
03:59 AM rue_shop3: it goes thru the 8 servos, and restarts
03:59 AM rue_shop3: and its bottom is 0.5ms
03:59 AM rue_shop3: so, the servo will have, worst case 4ms
04:00 AM rue_shop3: but typically 12ms
04:01 AM rue_shop3: at most 20ms
04:01 AM rue_shop3: cause I go to 2.5ms
04:07 AM Jak_o_Shadows: rue,what protocol?
04:08 AM Jak_o_Shadows: I was looking for one the other day, to get working with the pca9685
04:08 AM Jak_o_Shadows: (to test)
04:09 AM rue_shop3: well
04:09 AM rue_shop3: its a container, so I can just give you the whole thing
04:10 AM rue_shop3: https://paste.debian.net/982822/
04:10 AM rue_shop3: your interrupt driven stuff just needs to feed off the positions arrays
04:11 AM rue_shop3: sorry, thats what I have right now, its two arrays cause ... problems with 2am
04:11 AM rue_shop3: I have a better protocol thats supports 10 bit positions with up to 255 servos
04:12 AM rue_shop3: which I also have some manual operation software for
04:12 AM rue_shop3: I have C libraries that talk to that I pasted
04:12 AM Jak_o_Shadows: Is it simple for me to see that?
04:13 AM Jak_o_Shadows: I can't promise a nice gui, except actually I have one already that I just need to dig out
04:13 AM rue_shop3: I'm just chewing on a python interface with 16 sliders
04:14 AM rue_shop3: the other protocol has ping capability, so you can scan a bus for servos
04:14 AM rue_shop3: you want to see the other protocol?
04:14 AM rue_shop3: or that driver lib for what I pasted
04:17 AM Jak_o_Shadows: um. hmm. The driver lib for what you pasted
04:17 AM rue_shop3: k
04:18 AM rue_shop3: waaaaaaaait, a sec
04:18 AM rue_shop3: better give you a whole working example
04:19 AM rue_shop3: heh, no make file
04:21 AM Jak_o_Shadows: where the heck did my slider python interface thing go
04:22 AM rue_shop3: ok, this program is command line, you give it a serial port, an axis translation file, and a file with a list of positions and times, it plays the positions to the servos
04:22 AM mrdata: Jak_o_Shadows, must have been swallowed by a snake
04:23 AM rue_shop3: void playFile(char * filename) that is the function to focus on
04:23 AM rue_shop3: it does interpolation on the axies, and spools it out for speed control
04:24 AM rue_shop3: (sorry I dont have a simple example)
04:26 AM rue_shop3: http://ruemohr.org/%7Eircjunk/robots/arm9/roboplayer.tgz
04:26 AM rue_shop3: Jak_o_Shadows, ^
04:26 AM rue_shop3: the spooler itself is SSC8Spooler.*
04:27 AM rue_shop3: genServo is a generic servo library
04:27 AM rue_shop3: interlin2 is a interpolator library
04:27 AM rue_shop3: servoarm is an abstraction for the type of robot the program was written for
04:28 AM rue_shop3: SSC8Spooler is the spooler to the servos
04:28 AM rue_shop3: ssls3 is a "super simple linux serial" library, v3, which has some threading stuff
04:28 AM rue_shop3: and the transBuffer and transformer stuff are for applying the scale/offset stuff to the positions
04:29 AM rue_shop3: ... in the right light its a goldmine of code :)
04:31 AM rue_shop3: Jak_o_Shadows, still alive?
04:35 AM rue_shop3: ...or I could just make a text console interface....
04:36 AM rue_shop3: so, my other servo protocol,
04:37 AM rue_shop3: supports 256 servos per bus, you can ping them, do cascade and group updates, and query parameters
04:37 AM rue_shop3: it supports things like individual servo power on/off control
04:38 AM rue_shop3: but
04:38 AM rue_shop3: its only 10 bit
04:38 AM rue_shop3: (position data)
04:38 AM rue_shop3: the one I posted the stuff on, is a hack of the old SSC stuff
04:48 AM Jak_o_Shadows: yeah, yeah, still alive. had food though
04:48 AM Jak_o_Shadows: Thanks!
04:49 AM rue_house: k, do ask questions, there is a lot there
04:53 AM Jak_o_Shadows: Will likely be on the weekend
04:57 AM Jak_o_Shadows: found that code
04:58 AM rue_bed: just found some console code
04:58 AM rue_bed: needs lots of hacking
04:58 AM Jak_o_Shadows: https://bpaste.net/show/7efd923d72df - the GUI i made with sliders
04:59 AM Jak_o_Shadows: You'd need python 2.7, and you'll need to replace the connection & the protocol stuff
04:59 AM rue_bed: oh this looks good sofar tho
05:02 AM Jak_o_Shadows: whatever
05:02 AM Jak_o_Shadows: Python 2.7 is old anyways
05:04 AM rue_bed: so is everything on debian
05:05 AM rue_bed: dont even know if I can get 3 on debian
05:10 AM Jak_o_Shadows: surely
06:07 AM synja: there's even a version 2.7 to 3 processor
06:07 AM synja: install by pip
06:07 AM synja: it's called 2to3
06:07 AM synja: more of a code translation i suppose
06:08 AM veverak: /buffer MonikaSuchovska
06:08 AM veverak: fuuuu
06:08 AM veverak: :)
10:50 AM veverak: hmm
10:50 AM veverak: seems like Arduino ESP
10:50 AM veverak: is best experience for now
12:13 PM anniepoo_: hey rue, I'm alive
12:13 PM anniepoo_: combination of work crunch and solar eclipse made me AWOL a few days
12:22 PM anonnumberanon: sigh we still don't have a 32 servos control with 16 bit resolution for positioning all for the cost of $5?
12:22 PM anonnumberanon: guilty
01:23 PM deshipu: anonnumberanon: I have 20, 40 for $10
01:27 PM anonnumberanon: runs 20 or 40 servos deshipu ?
01:34 PM deshipu: a single shield runs 20, you can stack up to a 100
02:00 PM anonnumberanon: deshipu, how do I get?
02:04 PM deshipu: https://www.tindie.com/products/deshipu/20-channel-servo-shield-for-d1-mini/
02:04 PM deshipu: but I don't plan to sell any more of them
02:04 PM deshipu: I replaced them with a pca9685-based shields
02:07 PM anonnumberanon: You've been busy!
02:10 PM deshipu: I should probably make a new version with atmel SAMD21 now
02:16 PM anonnumberanon: I should finish mine too with the atmega328p just to see how good it can get.
02:16 PM deshipu: I had some artifacts when the servo positions were too close to each other
02:17 PM deshipu: not enough time to reset all the pins, etc.
02:17 PM anonnumberanon: I was kinda blocked by the frequency of the chip though if I wanted to refresh order faster. It still refreshed faster than a human can send orders, but if you start to do software operations on the orders then maybe that's when you need it to refresh very very fast.
02:18 PM anonnumberanon: As soon as my car work is done I'll get back to it. Everything is in a box in my room...
02:45 PM rue_house: synja, http://journal.frontiersin.org/article/10.3389/fnhum.2014.00166/full
03:11 PM rue_shop3: ok I realized how I could quick and dirty test part of the new servo controller and it works
03:16 PM anonnumberanon: good
03:16 PM anonnumberanon: now
03:16 PM anonnumberanon: make a humanoid biped with it
03:16 PM * anonnumberanon prepares extinguisher(s)
03:34 PM deshipu: are there humanoid hexapods?
03:38 PM anonnumberanon: no you should make one
03:38 PM anonnumberanon: torso, head, arms
03:43 PM rue_house: not with SG90's
03:43 PM rue_house: maybe MG90, but I dont have a budget for that
03:44 PM anonnumberanon: like you can't make your own MG90s...
03:44 PM anonnumberanon: Am I in #robotics?
03:44 PM anonnumberanon: or #socialstudies?
03:45 PM rue_house: I'v got a bunch of custom gearboxes that I made with {stuff} and the 3d printer, but I dont have a way I like of getting pot feedback
03:45 PM rue_house: that I WANT to do, is use pots with really big long shafts as the output shaft
03:45 PM rue_house: but I just cant find them from china
03:46 PM rue_house: so over the last 2-3 weeks I been coaxing myself to do it with an adapter of somekind
03:46 PM rue_house: no solutions have been accepted
03:47 PM anonnumberanon: <rue_house> that I WANT to do, is use pots with really big long shafts as the output shaft
03:47 PM anonnumberanon: you lost me at that point
03:47 PM rue_house: you can get a pot with a 4mm dia, 15mm long shaft
03:48 PM anonnumberanon: start sourcing motors, chips for the IC board, little gears
03:48 PM rue_house: but apparently not from china
03:48 PM rue_house: I have a lifetime of motors
03:48 PM rue_house: I have a lifetime of chips
03:48 PM rue_house: I have a few years worth of protoboard
03:48 PM rue_house: and I have 2 lifetimes of gears
03:49 PM anonnumberanon: and all that's stopping you is the shaft is too short?
03:49 PM rue_house: in a way, yes
03:49 PM anonnumberanon: is there a product where they have it?
03:49 PM anonnumberanon: does digikey sell it?
03:50 PM rue_house: dk does, if I want to pay LOTS of money
03:50 PM rue_house: but I cant find it from china
03:51 PM rue_house: oh geez, ok, I have to get organized,t he stores all close in 3 hours
03:51 PM rue_house: ewaste, need to make a trip to there...
03:51 PM rue_house: bag of cement, need another one of those...
03:52 PM anonnumberanon: you can just take all the stuff people leave in the ewaste?
03:52 PM rue_house: no there's a depo
03:52 PM rue_house: wow, the cement from yesterday actaull etched my skin
03:52 PM rue_house: didn't know it did that
03:55 PM anonnumberanon: always have a bucket of water and rinse your fingers at the slightest contact
03:55 PM anonnumberanon: i did some tiles with uncle this summer
03:55 PM rue_house: :) I was using my hands to appply it
03:56 PM rue_house: https://www.digikey.ca/product-detail/en/honeywell-sensing-and-productivity-solutions/53C110K/53C1103-ND/52050
03:56 PM rue_house: does that open?
03:57 PM rue_house: see what I mean? $15 ea
03:57 PM anonnumberanon: but that is huge
03:57 PM anonnumberanon: like it's almost 10 centimeters
03:57 PM rue_house: yes, its shaft would be the servo output shaft
03:57 PM anonnumberanon: this one is something you'd use in a lab, not within a small system
03:57 PM rue_house: its 1/4 of a servo
03:58 PM rue_house: thats the output shaft, attach gear.
03:58 PM anonnumberanon: == too big
03:58 PM rue_house: https://www.digikey.ca/product-detail/en/cts-electrocomponents/450D103PR16/450D103-8-ND/183276
03:58 PM rue_house: ooooh, ther's an idea
03:59 PM anonnumberanon: i got an emotional relationship with that pot you pasted
03:59 PM anonnumberanon: it's the first time i was able to change a value in a microcontroller with external action (my hands turning the pot)
04:00 PM rue_house: heh
04:00 PM anonnumberanon: then i turned a servo back and forth using that pot for like 45 minutes straight, just amazed
04:00 PM anonnumberanon: thinking about the future
04:01 PM anonnumberanon: starry eyed
04:01 PM anonnumberanon: :)
04:11 PM anonnumberanon: do you have very strong motors then? cause this is big hardware
04:12 PM rue_house: yea
04:13 PM rue_house: 20mmx30mm like
04:13 PM rue_house: and larger
04:14 PM rue_house: http://ruemohr.org/~ircjunk/tutorials/mech/gearbox/gearbox.html
04:14 PM rue_house: thjis was 10 years ago or more?
04:14 PM rue_house: I have about 2x everything now atleast
04:17 PM Tom_L: you should have 3x the shop space now too
04:18 PM rue_house: oh I see what I did wrong
04:18 PM rue_house: EVERY vcr, and tv I took apart, I THREW OUT the space that was in them
04:18 PM rue_house: I should have kept all that space
04:18 PM rue_house: I kept the screws, god knows...
04:19 PM Tom_L: never know when you might need a screw
04:19 PM rue_house: the more the better
04:19 PM rue_house: organized scerws are important tho
04:21 PM -!- #robotics mode set to +o by ChanServ
04:21 PM rue_house changed topic of #robotics to: If you ask a question, you must wait for the answer. | http://tom-itx.no-ip.biz:81/~webpage/index.php | M is for motor.
04:21 PM -!- #robotics mode set to -o by rue_house
04:34 PM rue_house: need to work on the screw sorter
04:34 PM rue_house: I think it gets them in the bins atleast 70% of the time
04:36 PM Tom_L: have a screw pick r up r to catch the other 30%
04:37 PM rue_house: I may work out another binnning system, but its important tog et the thing generally togethor
04:37 PM rue_house: 2:00 I have 2 hours left
06:31 PM rue_shop3: no hours left
06:32 PM rue_shop3: 112 hours into my vaccation
06:32 PM Tom_itx: where did it all go
06:34 PM rue_shop3: down the temporal vortex
06:43 PM rue_shop3: man I'm like dazed
06:43 PM rue_shop3: zhanx, you got any advice for being dazed?
06:43 PM rue_shop3: /stunned
06:44 PM Tom_itx: pull your finger out of the light socket
06:44 PM * rue_shop3 checks the locations of his fingers
06:44 PM rue_shop3: aside from one, their all good
06:44 PM rue_shop3: the servo library works tom
06:45 PM rue_shop3: I have 16 channels off two 4017
06:45 PM Tom_itx: that's great
06:45 PM Tom_itx: on the arm?
06:45 PM rue_shop3: bench :(
06:45 PM rue_shop3: the arm is only 6 axis
06:45 PM Tom_itx: i wish i could get to the bottom of my problem
06:46 PM * rue_shop3 swaps tom out with a smaller bottle
06:57 PM zhanx: rue focus on one spot. sit still, with knees up
06:57 PM rue_shop3: thanks, I'll try that.
06:58 PM rue_shop3: what if everything around that spot starts to spin?
06:58 PM rue_shop3: suppose I can just be confident its not really spinning
06:58 PM zhanx: that is the focus part. like a dancer that never gets dizzy
06:59 PM rue_shop3: I got servo control pulses generated via a 4017!
07:00 PM zhanx: i got wedding power plans to do in a minute. i am the wiring guy for this redneck wedding
07:00 PM rue_shop3: :)
07:21 PM synja: rue_shop3, the link you msged be before is interesting. i've been working on NLP (natural language processing) for quite some time in, and have considerable results from it
07:22 PM synja: the audio processing i was talking about before are related to pitch inflections as a function of each word, to determine sentiment and magnitude
07:22 PM synja: like, higher pitches from the baseline at the end of a sentence could be a question, or high emotional content
07:23 PM synja: there are only so many words where it can be a question though, so you can filter that out
07:23 PM synja: higher pitches in general from the baseline implies emotional content
07:24 PM synja: i took care of a blind minister once. nicest fellow i've ever met
07:24 PM synja: he told me he could determine if a person was lying from the sound of their speech
07:24 PM synja: it got me thinking. i had been working on microexpressions for a while, but this was an entirely different realm
07:25 PM Snert_: here we go. I am a billionaire.
07:25 PM Snert_: am I lying?
07:25 PM synja: no baseline to work from
07:25 PM synja: and i was talking about audio analysis
07:25 PM Snert_: right on...good answer.
07:25 PM synja: i've been working on text analysis for years
07:25 PM synja: great results
07:26 PM Snert_: you're a CIA analyist that decodes plain text messages into what they really meant.
07:27 PM synja: nothing that interesting
07:57 PM rue_shop3: well I ended up working on the loading dock more
07:57 PM rue_shop3: really close
08:37 PM rue_shop3: hmm what to work on
08:38 PM rue_shop3: screw sorter
08:38 PM rue_shop3: hexapod (32 servo stm32 code)
08:38 PM rue_shop3: 12' mecha (pipe bender or engine)
09:10 PM Snert__: hexapod. more fun.
09:10 PM Snert__: screw sorter? Well, I was never one to collect a bazillion screws anyways.
09:11 PM Snert__: let go of the hoarding thing.
09:11 PM Snert__: and I'm certainly guilty of hoarding too.
10:22 PM AltJesteR: greets all
10:41 PM mrdata-: yo
11:19 PM anniepoo_: 8cD
11:20 PM anniepoo_: screw sorter
11:20 PM anniepoo_: I think it's the closest to finished
11:20 PM anniepoo_: and finishing projects is happy making
11:30 PM rue_shop3: anniepoo_, you doing a screw sorter too?
11:37 PM rue_shop3: I'm going to move all the batteries out to the tent-of-disparity
11:37 PM rue_shop3: but I have to clean it out first
