00:10 rue_shop but it still needs porting, seems it was moderatly gutted to run on linux
00:11 rue_shop its only 10, I'm upset that I'm all tired already
00:11 rue_shop anyhow, I got some libraries to code in my room
00:14 katsmeow-afk k
00:57 rue_mohr if (x1 == x2 ) // this will be a bug later.
00:58 katsmeow-afk why?
00:58 rue_mohr because when you go to draw a line thats just one pixel it'll quit without drawing anyting
00:59 katsmeow-afk oh, i didn't see "pixel" in there
01:00 rue_mohr :)
01:01 rue_mohr hmm I cant remmeber the name of the C fn for filling memory with a value
01:01 rue_mohr memset
01:09 rue_mohr yay, I made a function that draws a horizontal line of ascii character
01:11 katsmeow-afk why not use a bitmap?
01:12 rue_mohr text console
01:12 katsmeow-afk text is often displayed as a bitmap
01:12 rue_mohr I'm advancing some libraries I have
01:12 rue_mohr think dos
01:12 rue_mohr I'm not installing a gui on the robot control computers
01:13 katsmeow-afk usually the hardware does the map lookup for each character
01:13 rue_mohr yes I only have acces to the character its mapping
01:13 katsmeow-afk umm, k
01:14 rue_mohr took me yeras to learn how to do cursor positoning under linux
01:15 katsmeow-afk i wouldn't do it *under* linux, i'd run it atop linux and call down tot he draw routines
01:18 katsmeow-afk that would be worse than running under dos, where you cannot call dos routines, and you call only bios and twiddle the hardware, like when writing device drivers
01:18 rue_mohr yay, verticle lines work
01:18 tsmeow-afk wrote some ramdrive soft
01:18 rue_mohr now I shal write box()
01:21 rue_mohr :( box fail
01:22 katsmeow-afk do i really like only 5 bands/singers that start with 'I' ?
01:22 katsmeow-afk and maybe not hat many
01:23 katsmeow-afk i don't remember much or Iron Maiden or Iron Butterfly
01:41 rue_mohr katsmeow-afk,
01:41 rue_mohr !assist images/foo.png
01:41 tobbor Possibly http://eds.dyndns.org/~ircjunk/images/foo.png
01:41 katsmeow-afk i already saw foo
01:42 rue_mohr noo foo
01:42 rue_mohr I overwrite foo all the time
01:42 katsmeow-afk ah, i see
01:43 katsmeow-afk ascii text formatting for a linux "dosbox" ?
01:43 rue_mohr for text console
01:44 rue_mohr I can draw boxes with any character I want
01:44 katsmeow-afk yeas,, have you looked at the olde dos Borland C C code? iirc, all the olde stuff is now open
01:45 rue_mohr yea, its a horrid mess
01:45 rue_mohr unusable for anything now
01:45 katsmeow-afk they had C code to draw "windows" boxes before Windows(tm)
01:45 rue_mohr yes
01:45 katsmeow-afk k
01:45 katsmeow-afk same with Turbo Pascal , Turbo C
01:45 katsmeow-afk Turbo other things too
01:46 rue_mohr its been ported, but they used the system called ncurses, which is an unstable library, the ncurses library was changed in a non-backwards compatible way and the borland stuff was never re-ported
01:46 rue_mohr I used to use turbo C
01:46 rue_mohr I know exactly of what you speak
01:47 rue_mohr but their code used a lot of direct bios calls, so porting it in the first place was a mess
01:47 tsmeow-afk
01:48 rue_mohr I was thinking of making a steampunk keyboard, building it from a typewriter
01:49 rue_mohr with tacticle switches
01:49 katsmeow-afk been done, beautifully too
01:49 rue_mohr it'd last longer than these things do
01:49 rue_mohr turnip has on olde keyboard I was looking at the construction of
01:50 rue_mohr simple, but intriquite pieces
01:55 rue_mohr yay! now I have a system to draw me a dialog box!
01:56 katsmeow-afk just fyi, there's peoples selling spring loaded test points on ebay, praps they can be modded to be the undersides of your new diy keybd
02:00 rue_mohr no I can something that feels like it buckles when you hit it
02:00 rue_mohr I want something that never heard the notion of ergenomic
02:02 katsmeow-afk the most pricey i can think of would be a computer controlled keybd with a servo under each key so you could program the pushback and sound of each key
02:02 rue_mohr hey now!
02:02 katsmeow-afk hmm?
02:02 rue_mohr remember I have code to do that linear actuator thing with simpel solinoids
02:03 rue_mohr hmm?
02:03 katsmeow-afk yeas, but that *might* be jerky, i dunno
02:03 rue_mohr did you not see my linear control of a solinoid?
02:04 katsmeow-afk would be mighty interesting tho, if you could wind your own selenoids in some steampunk fashion
02:04 katsmeow-afk i saw you control a selenoid, and i praised it many times
02:04 rue_mohr http://www.youtube.com/watch?v=4tG2bTOGxK0
02:04 rue_mohr ok
02:04 katsmeow-afk i think it's quite a deal
02:04 katsmeow-afk i saw it the nite you did it
02:04 rue_mohr I was really surprised it worked
02:04 katsmeow-afk i been here before
02:05 rue_mohr every so often someone misses something :)
02:05 rue_mohr the results of the air muscle were nice too, but getting those valves to co-operate is a pain
02:06 katsmeow-afk i thought they would
02:06 rue_mohr the pulse width and air volume are not at all linear
02:07 katsmeow-afk correct
02:07 katsmeow-afk and they are not stable
02:07 rue_mohr I think I can get enough control over it, but it wont be a walk in the park
02:08 rue_mohr on BIG air muscles, there is a lot of forgiveness in the air volumes
02:09 rue_mohr hmm
02:10 rue_mohr so tommorow I should be able to integrate the cursor position control stuff, and stuff to draw dialog boxes, and serial stuff into the program for controlling buddys servos
02:11 rue_mohr see if I can get him moving again
02:11 rue_mohr maybe spend the rest of the day getting overload boards etched
02:12 rue_mohr I made the 3 critical corrections, the rest of the problems assembling the baords is cause 2 sided is not happening for me
02:12 katsmeow-afk i can't find anything here yet, still wondering where my TL082 got off to
02:13 rue_mohr something went wrong after I calibrated my plotter and it dosn't flip properly anymore
02:13 katsmeow-afk or even the TL084, i don't wanna use LM324
02:13 rue_mohr hmm whats the unity gain on the 08x?
02:14 rue_mohr its under 1M for the 324 yes?
02:14 rue_mohr you need 6 of them?
02:14 katsmeow-afk for full voltage output it's like 25k for 324 and 1meg for 08x
02:15 rue_mohr ah
02:15 katsmeow-afk i forget, but the 324 is slow, not something i'd wanna drive a mosfet with
02:15 rue_mohr if you want I think I have enough 084 to send you some, ask now tho, cause it'd take about 2 mo to get there
02:15 katsmeow-afk driving a bipolar, where the base is 1v swing for full on to full off, isn't like a mosfet with a 10v swing on the gate
02:16 katsmeow-afk 2 mo?? one of my fav sellers is in Canadia, and he gets stuff to me in like 3 days
02:16 rue_mohr hu
02:16 rue_mohr unless I pay like $50+ on shipping, I dont think I can do that
02:17 katsmeow-afk dipmicro
02:17 katsmeow-afk occasionally he even beats Chinese prices
02:17 rue_mohr hey I'm just sayin I got some (I think)
02:17 rue_mohr its either 084 or 083
02:17 rue_mohr er...
02:18 katsmeow-afk there is no 083
02:18 rue_mohr ... brain not responding
02:18 rue_mohr 081 082 084 ....
02:18 katsmeow-afk yeas
02:18 katsmeow-afk 080 too
02:18 rue_mohr whats the other like it, fet based, but different
02:19 katsmeow-afk the 08x is fet, the 07x is bipolar, but from what i ear some oem are not paying attentiona nd are making 07x with fet inputs too
02:19 rue_mohr ah
02:19 rue_mohr yea 071 072 074
02:19 katsmeow-afk it matters on slew rate and capacitance muffling the high freqs
02:20 rue_mohr but 074 is the number that looks familiar
02:20 rue_mohr wonder if I have 074 or 084
02:21 katsmeow-afk the 07x is "brighter" but slower, the 08x needs a really low impedance driver to sound "bright", and it's not a low impedance driver itself, it'sike 200 ohms output
02:21 rue_mohr my attempt to stay awake is generating artificial results
02:21 katsmeow-afk the 324 is lower impedance, but still, it's slow for swinging a mosfet gate 10v
02:22 rue_mohr I think I usually use the 324 cause of how cloase to the rails its outputs go
02:22 tsmeow-afk
02:22 rue_mohr but they all suck for comparitors
02:22 rue_mohr on buddy I had to go 393, nothing else was even close to sensitive enough
02:23 katsmeow-afk yeas, some opamps have tight restrictions on how far apart the inputs can go before they fry
02:23 rue_mohr luckily, there are tonnes of 393 in computer power supplies
02:24 katsmeow-afk i am faced with using mosfets in my psu, you see my report this morning?
02:24 rue_mohr no
02:24 katsmeow-afk scroll up :-/
02:25 rue_mohr !thislog
02:25 tobbor This one: http://rueshouse.dyndns.org:82/~ircjunk/irclogs/html/%23robotics-2012-05-21.html
02:25 rue_mohr before that right?
02:25 katsmeow-afk 20
02:25 katsmeow-afk no
02:25 rue_mohr :25:50: ...katsmeow-afk:testing confirms i must use a mosfet pass transistor in the bench hexpsu
02:26 katsmeow-afk yeas
02:27 katsmeow-afk dropping a bipolar base , it will fall to gnd pretty fast, dropping a mosfet gate leaves it conducting, i may need a neg suply to pull that gate capacitance down without overloading the pullup
02:27 katsmeow-afk unless i drive it with the 324
02:28 rue_mohr yea, to get the voltag drop on the bipolars down enough you would have to burn up al your power on the base
02:28 katsmeow-afk yeas, i was at 4v drop worst case, i wol dhave had to goto a bigger transformer and more fans and heatsinks
02:29 rue_mohr how about using a diode to bring the - of the outputs .7V off the real ground so that you can drive the base to the real ground as a reverse bias
02:29 rue_mohr or just add 2 turns to a transformer to make a - bias supply
02:29 katsmeow-afk the transformer is *packed*
02:29 katsmeow-afk i cannot get even one more 18awg winding into it
02:29 rue_mohr oh, cmon, 3 turns of 22 guage wire?
02:30 rue_mohr just for a gate supply offset
02:30 rue_mohr :)
02:30 katsmeow-afk it's not just 3 turns, it's 3 x 6
02:30 rue_mohr oh I forgot their completely isolated
02:30 katsmeow-afk right
02:31 rue_mohr :) capacitor coupling off the ac windings before the rectifiers? :)
02:31 katsmeow-afk i already got the baggie of caps out for that
02:31 katsmeow-afk got another baggie on the way, tons cheaper, and many pounds lighter, than more transformer
02:32 katsmeow-afk [00:25] <katsmeow-afk> 50PCS 100uF 16V Electrolytic Capacitor ; 11 cents , free s&h
02:32 rue_mohr 11c ea or for 1...
02:32 katsmeow-afk sometimes, it's worth grabbing these things
02:32 rue_mohr ...?
02:32 katsmeow-afk 11 cents total
02:32 katsmeow-afk 11 cents for all 50 , free s&h
02:32 rue_mohr too cheap, I'm suspicious
02:32 rue_mohr tell me how it turns out
02:33 katsmeow-afk i'll test each before i use them, yeas
02:33 rue_mohr *blam*
02:33 katsmeow-afk or be like this other baggie of cheap caps, 1/2 of them are 1/2 value
02:33 e_mohr shocked look on face as he keeps his grip on the multimeter probes... "but....but
02:34 katsmeow-afk i have some 10,000u and some 27,000u , the 10ku test at higher value than the 27ku
02:35 rue_mohr I asked me to write that box libary, and I did, and now I'm not enough awake to know what to do
02:35 rue_mohr I dont feel like drawing
02:35 rue_mohr I'm thinking of starting a thing like xkcd
02:35 saschi haha
02:35 saschi what a "good" idea
02:35 saschi :D
02:35 katsmeow-afk anyhoo, eitehr way, under load the lowest volt psu is at 4.7v at 5amps (but ok, it's made for running low volt biases and 3/6 on down logics
02:36 katsmeow-afk at 4.7v, i will have a hard time making a opamp pull a gate up to 8v
02:36 saschi rue_mohr: what about programming a game with that stick man look?
02:36 rue_mohr saschi, .... you have an interest in such a thing?
02:36 katsmeow-afk so i haveto add transforemres to power the opamps from, or capacitor voltage boosters
02:36 saschi rue_mohr: in such a game? yes
02:37 saschi rue_mohr: would be awesome
02:37 katsmeow-afk xkcd isn't agame
02:37 saschi katsmeow-afk: u don't say?
02:37 tsmeow-afk bl
02:38 saschi and i mean "u don't say" in the sense associated with the face of nicolas cage in the movie "vampire's kiss"
02:38 rue_mohr I just think that there are a lot of things about a person raised on earth learing to live on a multiracial spaceship that would make funny cartoons
02:38 katsmeow-afk i didn't see that movie
02:39 saschi katsmeow-afk: http://static.fjcdn.com/comments/this+is+the+quot+you+don+t+say+quot+face+_d3d47eea8a14bd3a870bef4ef7e56686.jpg

02:40 saschi katsmeow-afk: http://www.youtube.com/watch?v=9Fvpyo2WuVY
02:40 saschi the movie
02:40 saschi okay, the relevant scene of the movie
02:41 tsmeow-afk has no sound, and nearly no bandw
02:41 saschi rue_mohr: well
02:41 katsmeow-afk Tiggr's miner on this puter is researching car turn signals
02:41 saschi rue_mohr: you already knew, that using the attribute "multiracial" is racist? :3
02:42 katsmeow-afk and whatever a "bipolar multiphasic pillbox antenna" is
02:42 saschi rue_mohr: since the common sens is, that there are no "human races" :)
02:43 katsmeow-afk but someone from anotehr planet is prolly not human, and is so a different race
02:43 saschi rue_mohr: if you'd brought that within your "sticky man" blog, a shitstorm would me granted :)
02:43 saschi s/me/be/
02:43 saschi rue_mohr: if you'd brought that within your "sticky man" blog, a shitstorm would be granted :)
02:43 rue_mohr if your on a ship with a bunch of other sentient beings that aren't human, are you gonna avoid saying its a multiracial ship?
02:44 saschi rue_mohr: well, you mean species
02:44 saschi rue_mohr: if you're really planning a sticky man style blog, you need to be very careful with the used terminology
02:44 saschi rue_mohr: or buy a proper shitstrom deflector phalanx :)
02:46 katsmeow-afk "hey Jones, i hear you're engaged to Glorbort!" "umm, nope" "but you patted "her" on the back in the turbolift, that's where their sex organs are located. Jones, you're engaged!"
02:47 rue_mohr haha
02:47 saschi katsmeow: *didntgetthepointbutlaughedhardnevertheless*
02:47 tsmeow-afk switches to the LM324 just to save time and about $10, and redesign and pcb space, and one charge pump per
02:53 rrywolf flops onto kat for bed
02:53 katsmeow-afk man the 324 is slow,, freq limit at 8vpp swing is 15khz
02:54 katsmeow-afk going to be slow driving a mosfet gate
02:55 furrywolf bbl
02:55 katsmeow-afk see, if i put in a charge pump to make a negative supply, i can drop in the TL08x opamps
02:56 katsmeow-afk furry is wake late!
02:56 furrywolf been working too hard all day. heh.
02:56 rrywolf curls back up on kat for goodnight pett
02:56 katsmeow-afk 10vpp swing on the TL08x is 400khz

07:41 Tom_itx gonna fry some hotdogs?
07:41 katsmeow-afk looks like i'm going to haveto wind a transformer to make power for the opamps on the hexpsu
07:42 m_itx heads out the
07:42 katsmeow-afk well, 1) it's 5kva, who else is gonna want it? 2) it's close enough to drive to iii) i can resell it for almost any money
07:44 katsmeow-afk 5kva = 240v@20a or 120v@40a , this is is also 480v@10a , i can maybe sellit to ham radio ops needing 600vdc at 10 amps
07:44 katsmeow-afk 600 = 480 * 1.4
07:51 katsmeow-afk ok, i need a small xformer with 6) 12v and 6) 6v windings, giving me 6) +15vdc and 6) -6vdc for etc
07:51 tsmeow-afk is eyeing those 300 cable b
07:53 katsmeow-afk they are 2-stage hi freq switchers tho
07:54 katsmeow-afk one of those will take up as much rooom as one EI iron core at 60hz with all the windings on it
08:12 katsmeow-afk thing is, wire size, i need only 300ma, and not all the time, the closest wire i have is 30awg
10:02 katsmeow-afk ok, got a 30vct xformer from a nukebox, i can separate the two windings and feed each to a 5v psu, that will give me 20v, which i can electronically split around the "ground" on the psu however i like
10:03 katsmeow-afk got a couple other transformers, untested, and more in boxes somewhere,, i should have somewhere tween 10 and 30 of them

11:56 Tom_itx no
11:57 Steffanx /kick iR0b0t1
11:57 iR0b0t1 Well, dang.
11:57 Steffanx Surprise!
11:57 Tom_itx Steffanx really?
11:57 Steffanx Yes
11:58 iR0b0t1 Okay fine.
11:58 iR0b0t1 Um.
11:58 Tom_itx site a reason
11:58 Steffanx He wants some entertainment
11:58 iR0b0t1 I'm kind of pissed that most robots which would be feasible for me to build involve the use of fasteners to create a body out of flat pieces of material which I cut,
11:59 iR0b0t1 and the motors and the gearboxes and the wheels were all premade,
11:59 iR0b0t1 and the microcontroller would probably have to be DIP because I can't design my own circuit board,
11:59 Tom_itx learn
11:59 iR0b0t1 and it wouldn't do anything unique because it all has been done before.
11:59 Squint ah, now THAT is a problem
12:00 iR0b0t1 I mean, my latest one is supposed to be a low cost teleopresence thing... I will get funding to make kits of it, if I do finish it, but it seems... lame?
12:00 iR0b0t1 I am also using too many ellipses, but I also have too many unfinished thoughts.
12:01 iR0b0t1 Aluminum extrusion, bolts, and wood, and these car window motors that I am literally swimming in.
12:01 iR0b0t1 IT'S LIKE GROWNUP LEGOS GODDAMNIT
12:01 Steffanx And now the problem..
12:02 iR0b0t1 ^ problem statement
12:02 iR0b0t1 ^ pointless rant

12:06 rue_mohr dont think lego, think meccano
12:06 rue_mohr start with metal that has a lot of holes in it
12:07 rue_mohr if you want to design a circuit board, take a stab at one and post it to us, we will find everything that makes it differ from a design that would work perfectly and last 40 years
12:08 Steffanx 40 years :S
12:10 rue_mohr what?
12:11 iR0b0t1 I'm not sure most uCs would last 40 years.
12:11 iR0b0t1 Heh
12:14 rue_mohr http://xkcd.com/371/ hah
12:15 rue_mohr they will
12:16 Steffanx :)
12:18 iR0b0t1 I think the problem is I always wind up with like half the parts I need.
12:18 rue_mohr did I ever tell you about the box?
12:18 iR0b0t1 Microcontrollers, but nothing to control, sensors, but nothing to sense, etc, etc...
12:18 iR0b0t1 Box?
12:19 iR0b0t1 No, probably not.

14:47 Steffanx Sorry, this is not the world.
14:50 rom i have a question for you #robotics- what does the most average/common modern-day robot look like?
14:50 zhanx this is like .0001x24E- of the world
14:50 zhanx rom industrial arms
14:52 rom fair point. who is the leading manufacturer? mitsubishi?
14:52 rom industrial arms in what environment? IC manufacturing? cars?

14:52 zhanx manufacturing of ANYTHING
14:53 zhanx that too when my bots gripper aint broke
14:53 zhanx i would think a delta bot is a close second to arms
14:53 zhanx with foxconn having all those machines and all
14:54 rom ok, I'll rephrase the question- what does the most common hobbyist robot look like?
14:59 duckinator rom: a line chaser? :P
14:59 ckinator has no idea; blindly gues
15:01 rom I ask, because I'm surprised there isnt a public standard yet. we've been making modern day robots for over 60 years and there isnt a standard robotics platform for testing/comparing AI systems.
15:01 joink is there financial interest in that?
15:01 joink there's buttloads of standards for different subsystems though
15:02 rom no, more importantly, theres an open source interest
15:02 joink but that often equals something along the line of herding cats
15:02 rom look at how much arduino, beagleboard and raspberry pi have caught on. i would have thought there would be a standard OS robot platform
15:03 joink all of those are really recent
15:04 rom arduino has been around for 7 years. look how much its grown. look how many people have gone into electronics/computer science because of it
15:06 rom just saying.. would it not be useful to have a standard to compare systems?
15:06 Skwint my 1st robot is an RC car with rear wheel steering
15:06 rue_mohr I think I'm gonna take a page from solarnrg, and convert the smelter to electric
15:06 Skwint my next one will be a hacked RC plane
15:06 zhanx rue_mohr: aint you suppose to be workin
15:06 Skwint I wish you luck making a standard AI for those two
15:06 rue_mohr I just paid almost $10 for 5L of diesel
15:06 rue_mohr holiday
15:06 zhanx nice
15:06 rue_mohr I'm sure I could smelt down a lot of aluminum for $10 in electricify
15:06 zhanx i slept 2 hours and the police woke me up
15:07 rue_mohr what did they need help with now?
15:07 zhanx the last renter here
15:07 Steffanx Yeah, sure
15:07 Steffanx You are the last renter :P
15:07 Steffanx For now
15:07 zhanx Steffanx: true
15:08 zhanx at least they didn't make the mistake of no-knock warrent
15:15 zhanx rue_mohr: saved the garden, the week I was gone, the gf never watered it,
15:15 zhanx only lost one plant
15:16 furrywolf ugh. pulled a muscle (I think) over my right breast. twisted the wrong way while loading firewood.
15:17 zhanx most likely a strained tendon
15:19 Steffanx IRC, where the old people complain about their little pains :P
15:19 Steffanx *small or whatever
15:21 zhanx from my view its the young ones that whine the most, the old people are just plain use to it
15:21 ace4016 i remember straining/tearing the tendon between my chest...i'm young and that was from a work out :D
15:25 Steffanx I guess so zhanx :P
15:25 Steffanx Or they just got banned
15:25 zhanx that too
15:25 Steffanx getting / whatever
15:26 ace4016 time to create an automated watering system zhanx? :P
15:26 zhanx my brain is fried from lack of sleep and yep I am attempting to work on that now for the code.
15:31 rue_mohr http://www.dansworkshop.com/wp-content/uploads/2011/09/30-Doing_another_pour_FUN.jpg
15:31 rue_mohr I think its steel sil plate
15:31 Steffanx Don't make solarNRG jealous
15:32 rue_mohr uh
15:33 rue_mohr furrywolf,
15:33 rue_mohr ... oh nevermind
15:42 zhanx watered the garden for nothing the sun is out and its pouring out now
15:42 rue_mohr its like insurance
15:42 rue_mohr I need to code
15:47 i-make-robots nothing novel, but nice to see how easy it can be: http://www.marginallyclever.com/2012/05/mecanum-tank-can-move-any-direction/
15:48 rue_mohr i-make-robots, hi
16:06 rom MECANUM WHEELS
16:06 rom TOO MUCH WANT
16:32 i-make-robots rue_mohr - hi
16:33 i-make-robots rom - yeah, and super easy to code if you have the L298 drivers.
16:34 i-make-robots thinking about putting together a PDF with instructions to make your own mecanum tank. download link after you pay "whatever you feel is right"
16:34 rom i saw a set of aluminium beasts, was thinking of hooking them up to some nema17 steppers
16:34 rom http://ma-vin.robosavvy.com/store/product_info.php/cPath/2036/products_id/2078
16:34 rom really expensive tho
16:35 i-make-robots sparkfun's are $76.
16:35 rom will look into the drivers, cheers
16:36 i-make-robots you know how to use PWM? then you can do everything you need to drive this vehicle.
16:37 i-make-robots I'm trying to find an iphone RC transmitter that plugs into the audio jack. actually, I'm having trouble finding the receiver.
16:37 rom ill save up for the beasts. im sure itll be worth it
16:37 rue_shop pwm is easy yes
16:37 i-make-robots rom - the trickiest part is attaching the motor to the frame.
16:38 rom im making my frame from scratch, no probs there.
16:38 i-make-robots i used duct tape for a 5 minute test. we tried 3d printing brackets but it wasn't great.
16:38 rom just cant find much reading material on mecanum wheels
16:38 i-make-robots not much to know. they work best on smooth flat surfaces.
16:39 i-make-robots when you turn them the wrong way, they just fight each other and movement is cancelled out.
16:39 i-make-robots (as happened the first time i tried to strafe)
16:39 rom ive got a cnc milling machine at work. will just buy 2m^2 of aluminium and make whatever shape i want :D
16:39 Tom_itx i've got one at home
16:40 rom yeah.. my initial thinking was stepper motors to drive them. i thought the more accurately timed the motors, the more perfectly horizontal i could get it to move......?
16:40 i-make-robots well, ok. those motors don't have mounting screw holes or anything. you can use steppers if you prefer.
16:40 Tom_itx steppers lose steps
16:41 Tom_itx and you can never find them again
16:41 i-make-robots steppers are probably overkill.
16:41 rom probably, but the standard shapes make for easier planning
16:41 rom drawing up the models as we speak
16:42 i-make-robots I made two different brackets that fit over each end of the motor and screwed to the frame.
16:42 Tom_itx rom what do you draw in?
16:42 i-make-robots 150mm/s printing on a reprap it was done in no time.
16:42 i-make-robots freecad?
16:42 i-make-robots solidworks?
16:42 make-robots giggles at the thought of sketc
16:43 rom no, real noob style. sketchup for the design then illustrator for 2d work, transfer it to autocad at work
16:44 rom never tried solidworks and i know i should. need to learn/acquire autocad first
16:48 i-make-robots try freecad.
16:49 rue_shop I like qcad
16:49 rom will do when i set up my linux machine
16:50 rom fyi, check out intense PC if you guys dont already know
16:53 rom its serious overkill, but i know loads of projects that use the old fit-pc models
16:53 rom find it hard to believe the i7 processor will only take up 5-15W
16:57 impulse32 anyone have a raspberry pi?
16:58 rom they dont exist
16:58 impulse32 oh still?
16:58 impulse32 when are they planning to ship them?
16:59 rom i work with a guy who has one. doesnt know what to do with it
16:59 rom lol
16:59 rom theyre shipping, but the demand is too heavy, theres a massive backlog
16:59 rom if you order now, you might get it next year
17:00 rom there are loads of alternatives
17:14 e_shop pokes any01939

17:55 rue_shop cool I put power on the controller bus for buddys servos and all channels went into standby
17:55 rue_shop this is *good*
17:56 rue_shop cool
17:57 rue_shop ttyUSB0
17:57 rue_shop ok I think buddys bus is 9600
18:03 rue_shop hmm, servo isn't responding
18:21 sw0rdfish hey
18:22 rue_shop I dont get it, its 9600 baud for sure
18:23 sw0rdfish damn rue_shop how do you find time for that stuff
18:23 sw0rdfish today I couldn't even find time to study either of my math or programming.
18:23 rue_shop well I finished school that helps
18:23 Tom_itx rue has been slacking lately

18:24 rue_shop software is supposed to go from 3 to -3A
18:31 sw0rdfish well give it to it! rue_shop
18:31 iR0b0t1 Anyone recommend a chip for sound playback?
18:32 Tom_itx i got one here somewhere
18:38 iR0b0t1 ISD1790 is one I saw, but I can't find any information on it. I think it is close to deprecation.
18:38 iR0b0t1 It's also like $6 per
18:39 iR0b0t1 But it does basically what I want, multiple sound slots and you give it a number to play, iirc.
18:39 ace4016 there was a few i saw on sparkfun a few years ago that were cheap
18:40 katsmeow-afk i picked up 300 sterio audio chips for free, serial input, mostly just dacs and volume controls
18:40 ace4016 think there's a attiny that does audio as welll...can't remember
18:40 katsmeow-afk followed by a chip for tone control
18:40 katsmeow-afk looking for 600 speakers to play them all thru now
18:41 ace4016 i think he's looking for a one chip solution :P
18:42 ace4016 although...that reminds me; i want to make a small radio >_>
18:53 iR0b0t1 ace4016: I've browsed the attinys thoroughly. There are 32bit AVRs which have audio capability, but not sure how that works, and they're a PITA to use
18:54 ace4016 hrm..maybe it was something else that I saw
18:54 ace4016 in know sparkfun had one though; i was planning a portable work platform at one point in time and it looked great to use
18:54 katsmeow-afk praps you can modulate the pwm fast enough to make audio
18:57 iR0b0t1 Not good audio :(
18:57 iR0b0t1 you can do beeps and stuff
18:57 iR0b0t1 which actually might be okay for me
18:57 iR0b0t1 but I wanted to do gun sounds and etc (lasertag)
18:57 Tom_itx how can you continue a line in javascript?
18:58 iR0b0t1 http://www.sparkfun.com/products/9534
18:59 iR0b0t1 holy tits that is expensive
18:59 iR0b0t1 Tom_itx: try \ slash?
18:59 ace4016 jeebus; not that one
19:00 ace4016 prices for this stuff seemed ot have gone up
19:01 rue_shop yay/boo its not a problem with the new controller code, the old program on windows dosn't work either
19:01 rue_shop so I wonder whats up that the controllers aren't talking
19:04 ace4016 different expect rates? starting them up in the wrong order?
19:18 iR0b0t1 http://www.sparkfun.com/products/9578
19:18 iR0b0t1 goddamn
19:18 iR0b0t1 everything is like $30
19:21 rue_shop they should just boot up and take on commands
19:22 iR0b0t1 http://www.sparkfun.com/products/8300
19:22 iR0b0t1 seems like that is more what I want
19:23 iR0b0t1 but still, sparkfun is horrendously overpriced
19:23 ace4016 they got even more expensive last i looked at them
19:32 iR0b0t1 http://www.sparkfun.com/products/8849
19:32 iR0b0t1 well anyway, that chip looks like it might work
19:33 iR0b0t1 but it seems wasteful, considering that thing has a CPU core in it.
19:40 rue_shop the only thing I can cant of is that the baud rates wrong
19:40 rue_shop but the old program dosn't work
19:40 rue_shop 103 @ 16Mhz
19:41 rue_shop http://ruemohr.org
19:41 rue_shop oh I can use ruemohr.org for the xkcd ripoff I wanted to start
19:41 rue_shop cook
19:41 rue_shop l
19:42 rue_shop http://www.wormfood.net/avrbaudcalc.php
19:42 rue_shop 103 -> 9600
19:42 rue_shop I just dont get it
19:55 Tom_itx check yer converter
19:56 rue_shop its ok
19:56 rue_shop so is the serial hub
19:56 rue_shop if I loop it back right at the controller its good
20:03 iR0b0t1 Is there a low cost RF thingy for sending voice?
20:03 iR0b0t1 That or low baudrate data
20:09 summersault Leap or Kinect . Which is better for 3d scanning ?
20:16 ace4016 never heard of leap
20:19 ace4016 ah
20:19 ace4016 doesn't seem like it's quite the same
20:19 ace4016 it's targetted at just the hands and a fairly close distance
20:20 ace4016 kinect more so from afar and the whole body
20:20 ace4016 (the'res some skeletal info as well and such)
20:20 ace4016 so yea...not quite the same, so it depends on what you need it for
20:32 summersault Can leap be modified for tracking 3d information ? I saw in a video, a 3D scanned hand by leap, and the reach is about 8 feet.

21:17 furrywolf meh, my internet connection is very dead today.
21:18 katsmeow-afk so just where is the 5gph super low powered high pressure water pump?
21:34 katsmeow-afk furry?
22:53 rue_mohr aha!
22:53 rue_mohr I think I found the problem!
22:53 rue_mohr I rewrote the command protocol
22:54 rue_mohr meaning there may be no working control client right now
22:56 rue_mohr 0 listen (servo number) 256 = all {always obey command} // sticks through listen once
22:56 rue_mohr 1 ignore (servo number) 256 = all {always obey command} // overrides listen once
22:56 rue_mohr 2 One Time listen (servo number) {always obey command}
22:56 rue_mohr 3 set flags (flags) { bitwise obey }
22:56 rue_mohr 0 enguage cached position {always obey command}
22:56 rue_mohr 1 turn servo on {obey if listening}
22:56 rue_mohr 2 turn servo off {obey if listening}
22:56 rue_mohr 3 set cmdpos to curpos {obey if listening}
22:56 rue_mohr 4 set servo position (position) {obey if listening}
22:56 rue_mohr 5 set cached position (position) {obey if listening}
22:56 rue_mohr 6 get servo current (servo number) {servo number}
22:56 rue_mohr 7 get servo position (servo number) {servo number}
22:56 rue_mohr 8 send device model (servo number) {servo number}
22:56 rue_mohr I'll have 8 toggle the debug
22:57 rue_mohr no I need soemthing always obeyed
22:57 rue_mohr ok I'll just use listen
23:12 rue_mohr the 16 bits are still split up the same tho
23:13 rue_mohr the verry last thing I did must have been to rewrite the protocol
23:13 rue_mohr bastard
23:19 katsmeow-afk The Obama administration on Thursday ordered tariffs of 31 percent and higher on solar panels imported from China
23:19 katsmeow-afk Those measures follow the U.S. Commerce Department's duties of 2.9 to 4.7 percent imposed in March on Chinese solar panel imports
23:22 rue_mohr hahaha what an amazingly backhanded way to support the oil industry
23:23 katsmeow-afk Canada announced in March it would eliminate the 1-cent piece from its economy. The Canadian Mint will no longer make the coin
23:23 rue_mohr yea
23:23 katsmeow-afk The Pentagon in 1980 stopped shipping pennies to overseas military bases because they are "too heavy and not cost effective to ship." It costs the federal government 2.4 cents to make a penny.
23:23 rue_mohr its to the point everyone uses the penny as a formality
23:24 rue_mohr nobody is too broken to hear it go
23:24 rue_mohr everyone is thankfull to hear the end of $xx.99 prices
23:24 rue_mohr damnit I have to go clean the kitty litter box
23:25 rue_mohr I should have done this when there was still light outside
23:25 katsmeow-afk the price will prolly be the same, but in theusa they'll round against the customer, so $2.99 will finally be $3.00
23:26 rue_mohr I'll say that it works fine for australlia
23:26 katsmeow-afk gasoline won't be $3.699 any more, it will be $3.70
23:26 rue_mohr no they will never drop the 3rd place on gas
23:26 rue_mohr I dont know why
23:27 rue_mohr my new servo protocol for buddyis pretty different
23:27 katsmeow-afk it lies to the customer is why
23:28 katsmeow-afk the customer sees "$3.69", and expects 2 gallons will cost $7.38 , but the gas station legally charges $7.40
23:48 rue_mohr I havn't heard from furrywolf ...
23:51 GuShH rue_mohr: last time she talked she mentioned lifting a heavy bench and feeling sick afterwards
23:52 GuShH rue_mohr: I asked because she left ##electronics and I wanted to know why
23:52 katsmeow-afk "he"
23:52 GuShH again with this shit
23:52 e_mohr wonders how the gender of furrywolf got all mixe
23:52 GuShH look I asked and everyone said furrywolf is a she
23:52 rue_mohr katsmeow-afk, dont be so sure?
23:52 katsmeow-afk lol
23:52 GuShH before I've been calling furrywolf a he.
23:52 GuShH I'm sick of it
23:53 katsmeow-afk use gender-neutal pronouns?
23:53 GuShH it's hard in English
23:53 rue_mohr katsmeow-afk, ever heard a guy refer to his breast?
23:53 katsmeow-afk te , etc
23:53 GuShH katsmeow-afk: what is furrywolf then
23:53 katsmeow-afk yeas, not often tho
23:53 rue_mohr cause, uh..
23:53 rue_mohr k, well I wont draw judgement on that then...
23:53 e_mohr taps on furrywolfs shou
23:54 rue_mohr furrywolf, ...hello...
23:54 GuShH It's none of your or my business but if furrywolf is a she who also happens to be lesbian, I don't care - But I care about the first portion --- the gender. Simply to properly address the person
23:54 rue_mohr I dont care about any of it, but I'm damn curious now
23:54 katsmeow-afk praps we should ask then
23:54 GuShH Well, if I'm a guy and you call me "she" I'd at least tell you I'm a guy
23:55 GuShH The sexuality portion doesn't matter at all
23:56 GuShH In any event maybe furrywolf is in bed with back pain
23:56 tsmeow-afk hopes there is no pain invo
