00:10 rue_house hi again
00:11 r0b-_ i havent talked to you all day lol
00:12 r0b-_ ok at .19 seconds to move 60 degrees whats that for 360 1.2 seconds?
00:13 anx show r0b-_ a calcul
00:13 r0b-_ ok
00:13 r0b-_ i get about 72RPM
00:13 r0b-_ :P
01:01 wildmage amigojapan, from japan?
01:05 r0b-_ made in japan :)
01:17 rue_house wild!
01:17 rue_house looooong time!!!!!
01:17 rue_house hows research!?
01:25 wildmage doing well
01:25 wildmage actually, i'm almost done with the project
01:25 wildmage i've got my snake robot going through junctions and mapping them
01:25 wildmage now I need to make sure it can travel through multiple junctions and build a coherent map
01:25 wildmage this is all without external sensors
01:25 rue_bed cool
01:26 wildmage after all this time, still no one has done this kind of research on sensor-challenged environments or mobile snake robots
01:26 rue_bed built or simulated?
01:26 wildmage simulated
01:26 rue_bed k
01:26 wildmage i have no time for a real robot :)
01:26 wildmage besides, that's all anyone else works on in snake robots
01:26 rue_bed heh, you need to gather up money and hire me to make one for you!
01:26 wildmage they spend all of their time and money building novel mechanical systems
01:26 wildmage no one has actually built the software for its autonomous behaviors
01:27 rue_bed heh
01:27 r0b-_ well rue
01:27 wildmage Prof. Khoshnevis still remembers the device you made for his lab
01:27 wildmage i think he still has it
01:27 rue_bed here I am working on a lowly open src ladder logic modbus plc
01:27 rue_bed :)
01:28 rue_bed gnight
01:35 r0b-_ you sleeping/
01:44 amigojapan_ wildmage: I am a mexicacn that lives in japan
01:44 amigojapan_ mexican*
01:45 zhanx mexicant spell
01:47 r0b-_ well just ONE more hurdle :)
01:49 wildmage amigojapan_, how the heck did that happen? Were you abducted? :)
01:49 wildmage going to school there perhaps?
01:51 wildmage japan is a good place to learn robots from the mechanical engineering aspect
01:51 wildmage lots of innovative systems being built
02:09 the_jester greets to room
02:09 the_jester '
02:10 r0b-_ hi
02:11 the_jester hi r0b-
02:11 r0b-_ how are you
02:12 the_jester im good, what cha working on?
02:12 r0b-_ rover
02:13 the_jester pics?
02:13 r0b-_ nah
02:13 r0b-_ no design yet
02:13 the_jester ahh
02:14 the_jester im watching my bread board arduino blink away, thinking about hexapods
02:15 zhanx oct
02:15 zhanx 8 is better than 6
02:15 r0b-_ wheeled!
02:15 zhanx tracked
02:16 r0b-_ wheelk!
02:16 the_jester simple 3 servo hexapod, just for fun.. toy for my cat mabey
02:17 the_jester i like tracks personally, have built a few tracked toys
02:17 r0b-_ i havent built anything
02:19 the_jester r0b- my best advice is goto a thrift store, good will kinda place and find a neat rc toy tohack apart, if you can find something with tank treads.. all the better
02:19 the_jester that was my first bot
02:20 r0b-_ well im gonna visit my LHS this weekend
02:20 r0b-_ pick up a few servos and some airplane wheels
02:20 r0b-_ or next weekend
02:22 the_jester what are youg o
02:22 the_jester arg
02:22 the_jester what are you gonna build?
02:23 r0b-_ just a simple 2 wheeled rover
02:25 r0b-_ right now im focused on the chassis then i will make it do something like follow a line or avoid stuff
10:59 r0b-_ zhanx_:
10:59 r0b-_ :o
16:49 aggrav8d so i need some market data, surveys, whatever. what would you pay for a 6DOF robotic arm, and what would you use it for?
16:58 zhanx 6 bucks
16:58 zhanx cleaning my house
16:58 Tom_itx to pour a beer
16:58 zhanx that too
16:58 Tom_itx i mean, it's obvious
16:58 Tom_itx geesh
16:59 zhanx that is what i should have made a waiter for me, remote controlled
17:00 Tom_itx ok i should take this laptop apart tonight
17:00 Tom_itx since the parts are likely to be here tomorrow
17:00 zhanx i would wait till tomorrow so you dont lose parts
17:01 Tom_itx why would i do that?
17:02 Tom_itx it needs to be back in service asap
17:03 Tom_itx i just hope the iron i have will desolder the jack
17:03 Tom_itx now's about the time i could use a solder station
17:04 Tom_itx i'll see if i can find those tyco parts tonight too
17:05 Tom_itx the 8x .1 screw terminals
17:12 Paradoxial aggrav8d: How large is this robotic arm?
17:49 aggrav8d 50cm reach. no stats yet on repeatability. definitely <5mm, working to replace some shitty parts and get <1mm.
18:02 Paradoxial aggrav8d: How fast/powerful is each joint?
18:03 aggrav8d 1kg payload at the tip. haven't finished testing how fast i can go.
18:03 aggrav8d I can't even show you a picture right now for legal reasons. :P
18:03 Paradoxial Is it an industrial bot?
18:14 aggrav8d could be. i mean, i made the damn thing. it could be for any purpose.
18:26 zhanx attach tracks for me so it can get me beer
18:26 zhanx and i will buy itt
20:01 rue_house .
20:02 rue_house !assist robots/arm4
20:02 tobbor Possibly http://eds.dyndns.org/~ircjunk/robots/arm4
20:02 rue_house oops wrong one
20:02 rue_house !assist robots/arm5
20:02 tobbor Possibly http://eds.dyndns.org/~ircjunk/robots/arm5
20:02 rue_house http://eds.dyndns.org/~ircjunk/robots/arm5/p1020977.jpg
20:03 rue_house that seriously needs an update
20:12 the_jester greets
20:12 the_jester rue here/.
20:12 the_jester ?
20:12 the_jester or tom
20:12 rue_house yea
20:13 rue_house I'm gonna go start a fire tho
20:13 anx points out
20:13 rue_house are you still in the house?
20:13 the_jester hows it going?
20:13 rue_house ok
20:13 rue_house just got 2 truckloads of cedar
20:13 the_jester mm
20:14 Tom_itx that outta burn fast
20:14 the_jester lots of kindling, try to find some fir or the absolute best is hemlock
20:15 rue_house we'll see, it was 'free'
20:15 rue_house 1/8 or so tank of gas
20:15 the_jester tom, fyi i didnt have to reset the fuse bits again, lfuse 0xff was correct,my external clock sources were at fault
20:15 Tom_itx i saw that
20:15 rue_house the_jester, are the modules ok?
20:16 the_jester been blinking for 2 days now
20:16 rue_house thats dependability right there
20:16 rue_house how about the arduino code?
20:16 zhanx suppose i should get my HaD merit badge and get one for rue while i am at it
20:16 the_jester ya, i wired them ass backeards but didnt kill them, might be inaccurate now but whatever right, 1,89mhz is only for rescue
20:17 rue_house zhanx, ?
20:17 zhanx https://www.adafruit.com/products/503
20:17 the_jester arduino code compiled and uploaded via Rue_prog and avrdude_win
20:18 rue_house haha
20:18 the_jester lol@had badge
20:18 rue_house ok I go start fire, biab
20:18 Tom_itx set the lawn while you're out there
20:19 the_jester seems like a HaD Badge should be hackable and feature an onboard arduino pic or propeller, but mostly arduino.
20:19 the_jester hes savving it for mower testing in the spring
20:20 Tom_itx naw, that's where all the stray nuts n bolts go
20:22 the_jester i bought some glow stick toy yesterday for a buck cause i thought it had a rgb led in it, turned out to be a r,g & b led and a blob top
20:22 the_jester bt they are nice leds for blinking..lol
20:22 the_jester might try using the pwn next
20:23 the_jester althogh it seemed to me i couldent get fade to run the otherday
20:23 the_jester i wanna make a robot
20:24 Tom_itx nothing stoppin ya but the doing
20:24 the_jester if i had some spare micro servos i could build a pololou ghexapod clone and use a ic socket to build the controller dead bug style
20:34 the_jester http://www.lynxmotion.net/viewtopic.php?f=10&t=3715
20:35 the_jester i like the design of that one although i cant help but think instead of an aluminum plate it should be the pcb
20:43 rue_house ok fire started
20:44 rue_house the_jester, you want to borrow that 3 servo I have to play with sfotware?
20:45 the_jester ya definatly but i dunno i cant help but feel i should build my own
20:46 the_jester mabey i should try to get that baby board 2 going and resserect my mini sumo first?
20:46 rue_house but it'd give you a running start
20:46 the_jester true
20:46 the_jester small baby steps
20:47 the_jester if i get to carried away i wil hit the wall, get frustrated and give up
20:47 the_jester as per usual
20:47 rue_house but having a platform lets you play iwth operating the servos
20:51 the_jester ya, i dunoo, i should really be tring to modify my programmer setting in the arduino ide so i can upload directly out of the ide and skip the command line and avr dude
20:51 the_jester im close
20:51 the_jester blink blink blink
20:51 rue_house ok well
20:52 rue_house cant thelp, report progress
20:52 the_jester actually on off on off with 25ms delay then on 100ms, off 100ms and loop
20:52 the_jester green led today, was blue yesterday
20:53 the_jester bought 3 leds and a pcb mount momentary contact switch at the buck or two yesterday
20:53 the_jester was alot of excess packaging, can you belive they hid them in a toy?
20:54 rue_house they are trickey buggers
20:55 the_jester i thoght i was getting a rgb led, i kinda did but not in one cozy package
20:55 the_jester i was looking at this one toms site
20:56 the_jester http://tom-itx.dyndns.org:81/~webpage/how_to/atmega168/mega168_rs232_index.php
20:56 the_jester which will help me add serial support to my bread board
20:57 the_jester i belive the arduino guys use ack or similar to reset the avr after serial uploading
20:57 the_jester i suppose that would need to be buffered by the 232 aswell?
20:58 rue_house 232 is +-12V, and its inverted
20:59 the_jester DTR
21:00 rue_house all the levels are +-12
21:01 the_jester whoa whoa, its is a ttl level convertor is it not?
21:02 rue_house the max232 is
21:02 rue_house I'm only half paying attention, kat has reamed me out about this
21:02 the_jester pin 11 and 12 are ttl level and 13/14 are serial level?
21:02 rue_house hmm
21:02 Tom_itx duely earned reaming
21:03 the_jester its that the point in the chip?
21:03 rue_house pff
21:03 rue_house Tom_itx, you have a max232 schematic?
21:03 the_jester oh fuck me
21:03 rue_house ?
21:03 the_jester ^^^ link is up there
21:03 Tom_itx yes
21:03 rue_house huh
21:03 rue_house jester, be nice now, sometimes we have kiddies in here
21:04 the_jester Warez Kiddies?
21:04 rue_house so there 13&14 are rs232 levels
21:04 Tom_itx mmm
21:05 Tom_itx somewhere
21:06 Tom_itx http://tom-itx.dyndns.org:81/~webpage/misc_stuff/rs232_sch.png
21:06 the_jester ^^^ ya there
21:07 the_jester Woot!
21:08 rue_house woot!
21:08 the_jester pc end dtr -> max232 pin 8; max 232 pin 9 -> avr reset
21:08 rue_house (what are we wooting?)
21:09 the_jester pin 1 on 168
21:09 the_jester via a 1 uF ca i guess
21:09 the_jester cap
21:10 the_jester which would enable serial upload via the bootloader.. but i cant do that yet since my 16mhz xtal is closer to 17mhz and that would probley mess up the serial timing
21:11 Tom_itx rue_house
21:11 Tom_itx http://www.youtube.com/watch?feature=player_embedded&v=nn2h3_aH3vo
21:11 Tom_itx can you relate?
21:14 rue_house heh, no tree up yet
21:14 the_jester ROFL @ simons cat
21:14 the_jester ive been there
21:16 the_jester kitty is up tree, puppy wants to play in tree with kitty, oh wait look tree is in dirt, dig dig dig, tree falls down, kitty runs dog chases lights are now attached to tree and kitty, tree chases cat and dog across basemsnt suite hayley and corey clean up dirt
21:16 the_jester corey points at mouth
21:17 the_jester being married wasnt all bad while it lasted i guess
21:17 Tom_itx wasn't that long iirc
21:17 rue_house hehe
21:18 the_jester 8 months or so?
21:18 the_jester hehe
21:18 Tom_itx that wasn't married. that was just playing house
21:18 the_jester she was pretty cool until the cocaine fuels meltdown
21:19 the_jester fueled
21:19 the_jester i could employ a small staff just reviewing and correcting my spelling, typing and gramerical errors in irc
21:20 the_jester if i jobbed it out to china i could afford the wage even
21:22 the_jester and thats whats wrong with the global economy guys like me with a staff of 20 for $5 a day reviewing irc post, only to have the english be more broken and less readable after the whole process
21:23 e_jester points at m
21:23 the_jester moew
21:24 the_jester oh geez, arduino room some guy asking, okay so com is neg right?
21:24 the_jester sorry com is ground?.
21:24 the_jester assume nothing i guess
21:25 the_jester wouldent want to smoke your 0.07 led
21:25 Tom_itx tell him it's the generally accepted suffix for a website
21:26 Tom_itx it wouldn't smoke an led, it just wouldn't illuminate
21:27 the_jester i said com is usually a suffix for a website, what does ths have to do with anythng, Madness....
21:27 the_jester :)
21:27 Tom_itx ask em what the nets are for
21:28 the_jester as if the guy isnt confused enough already
21:28 Tom_itx or wahat is a net
21:29 Tom_itx i stay outta there
21:29 Tom_itx no need to deal with morons
21:30 the_jester its good for instant answers to arduino questions, the gurus sit quietly in the bachground at watch the masses squable over the bones like wolves
21:32 the_jester besides, seems to be about my speed now days
21:33 the_jester and for the record technically im still married, been so for 5 years
21:34 Tom_itx i thought you left
21:34 the_jester makes me feel good when i date girl that are younger and hotter than my wife cause it doent make her feel good :P
21:35 the_jester i havent lived with her for like 4.5 years..lol
21:37 Tom_itx probably just as well if it's like you say
21:37 the_jester I wake up to someone knocking on my bedroom door at 9am, i figure its a room mate, fling the door open... and theres wifey with 2 cups of coffee, meanwhile hot slutty g/f is crashed in my bed
21:38 the_jester lol...
21:38 Tom_itx tmi
21:38 the_jester i had coffee with her and my slut g/f.. was a little aqward
21:39 the_jester what a mess, ruined my life frankly once upon a toime i had a good job and saving ect, not im screwed over and broke
21:40 the_jester meh, you dont care anyway, i'll shut up
21:40 e_jester goes out to s
21:40 Tom_itx if i had a dime for every story...
21:41 zhanx you could get a cup of coffee
21:41 zhanx from star bucks
21:41 Tom_itx probaby not
21:41 zhanx i dont drink coffee so no clue
21:42 Tom_itx me either
