00:01 rue_shop for each address, where A is the address and D is the data at that address
00:02 rue_shop Priority | Qualifier | Modifier
00:02 rue_shop -----------------------------------------------
00:02 rue_shop -10 1 n=A+1
00:02 rue_shop -20 1 D=n&0x7F
00:02 rue_shop -30 1 c=A/128
00:02 rue_shop -31 1 c=c&0x7F
00:02 rue_shop -40 n<c D=D|0x80
00:02 rue_shop n is the next address, which is programmed to the low 7 bits of the data for use as the next address
00:02 rue_shop c is the high 7 bits of the rom, which is the input pwm value
00:03 rue_shop its trimmed to 7 bits also
00:03 rue_shop if n<c the high bit of the data is set so, D7 is the pwm out
00:04 rue_shop D0-6 is fed back to A0-6 at 128X the pwm freq, A7-13 is the 7 bit pwm input value, and D7 is the pwm out
00:05 rue_shop who wants the .hex file?
00:06 rue_shop all you need is a 128k rom and a 74374
00:06 rue_shop and you have a slave pwm controller
00:07 fckng_stupid i ned a stable place to live first
00:07 e_shop
00:10 theBear that hurts my head
00:12 kng_stupid places hack kitten on thebears head and switches her to "knead"
00:13 rue_shop theBear, can you understand how it works?
00:13 rue_shop rigt now I feel liek I'm the only guy int eh world that understands state machines at all
00:14 theBear mmmm, inner-scalp-massage
00:14 theBear you're the only guy that over-understands them, and i just woke up from barbituates and anti-convulsives, i'm a bit dopey for err, what time was it last night ? about another umm, 10 hours
00:14 theBear not to mention a sixpack on instant noodles and an empty stomach
00:15 theBear but that's like a sip of beer for most people, just i'm more bear like
00:18 rue_shop hmm I forgot a input latch
00:19 rue_shop it would take 2 octal latches and the rom to do this, but it would only require 1 io address
00:19 theBear anyone know how hard it is to break into and remove the key barrel on a mid-late 90's holden ?
00:19 rue_shop the 8254 requires 3 io addreses
00:19 rue_shop you need to get into your car or someone elses?
00:22 theBear guy that used to live here... the neighbors won't raise an eyebrow, they seen me working on it and his other car before
00:22 rue_shop heh
00:22 rue_shop getting in isn't the problem
00:23 theBear it isn't ?
00:23 rue_shop getting a barrel out is a problem
00:23 theBear it is ? don't you usually just remove the plastic cover and undo a screw ?
00:23 rue_shop well I dunno
00:23 theBear maybe wiggle the steering wheel if it's jammed on the steering lock
00:23 rue_shop dont know if you can without the key
00:24 theBear hmm... bit of a wiggle, yeah, surely
00:24 rue_shop I have 4 control lines on the parallel port
00:24 kng_stupid cannot imagine Abraham Lincoln speaking H
00:24 theBear plus the 'switch' it pokes into (as well as the steering lock hole) is usually easily removable too, assuming the 2 pokey bits at right angles to each other stopped you getting it out
00:24 rue_shop if I want to talk to an 8254, I need a rd and wr line
00:24 theBear lol
00:25 theBear he's got the beard for it
00:25 rue_shop 2 address lines
00:26 rue_shop so it would eat up the whole parallell port
00:26 theBear remember you got a few control lines in there, more than 2
00:26 rue_shop but anything I do I need rd and wr
00:27 rue_shop 4, but I need 2 address lines, /wr and /rd
00:27 rue_shop thats the whole port
00:27 rue_shop I have 4 8 bit ports if I do that
00:28 rue_shop if I use 4 bit ports, I can have 32 of them
00:28 rue_shop + /rd and /wr
00:28 rue_shop 4*8 = 32 bits
00:28 rue_shop 4*32 = 128 bits
00:29 kng_stupid would rather do a 4-port ram, so the fsm can do an instruction fetch, plus dual reads, and a write, in one c
00:29 rue_shop so if I'm working via the parallel port, I'm better off making all the io 4 bit
00:30 rue_shop I can implement 2 independant 3 bit pwm systems in a 128k rom, use the 4th bits of the ports for direction
00:30 rue_shop OR
00:30 rue_shop I say screwit to the parallel port and use the IDE port
00:30 fckng_stupid <perk?
00:31 rue_shop then I get 16 bits, * 8 ports
00:32 telsek hello?
00:32 rue_shop hello
00:32 telsek how are you?
00:32 rue_shop I dont know, my last conclusion is that the odds are unfathomable
00:33 telsek nice
00:33 telsek that was a better answer then i had...
00:34 kng_stupid wouild like to point out that there's no other un-<measurement standard>-able w
00:34 fckng_stupid un angstomable , uninchable , etc
00:37 fckng_stupid ...
00:38 fckng_stupid !ping
00:38 telsek !ping
00:39 fckng_stupid hmm
00:39 telsek yes?
00:40 fckng_stupid no
00:40 telsek well, goodnight gentelmen
00:41 fckng_stupid <cough>
00:54 rue_shop this is why I dont get stuff done
00:54 rue_shop I got a digital scope I want to make but I dont want to start simple
00:54 fckng_stupid what if they don't know what ablutions are?
00:54 rue_shop and I got a few pwm cards for robots I wnat ot make but I cant decide to go parallel port or ide port
00:55 fckng_stupid <perk>
00:55 rue_shop ?
00:55 fckng_stupid hmm?
00:55 rue_shop I want to make it small, but my robots have tonnes of space
00:56 fckng_stupid fill that space with more robots
00:56 rue_shop I shoudl make a scope
00:56 rue_shop something, anything
00:57 fckng_stupid i should go lay down
00:57 rue_shop use the avrs onboard adc
00:57 rue_shop then I would ahve something
00:58 rue_shop heh too deadlocked on how I want to do it to get anything done
00:58 rue_shop its like a rev limiter
00:59 rue_shop annoying as all hell
00:59 fckng_stupid drive 6vac into a 9vac transformer, get 80vac out, or 110v-pk, regulate down to 70vdc
00:59 rue_shop I'm willing to put aside the input amp for now and just ameka 0-5V scope
00:59 rue_shop add the input amp later
01:00 fckng_stupid k
01:00 rue_shop so, avr and serial port?
01:00 fckng_stupid k
01:00 fckng_stupid gnites
01:00 rue_shop data format? command syntax?
01:02 rue_shop I'd like to make a successive approximation tom image too
01:02 rue_shop /rom/
01:16 rue_shop hmmm
01:17 rue_shop it makes an avr with a serial port and built in pwm system an awefull lot better
01:17 rue_shop both mcs48 and mcs80 need to either do bit banged serial or have a controller available
01:18 rue_shop by the time I have to wire up an eprom to a chip and add an io controller
01:18 rue_shop not including coding it in asm
01:19 rue_shop ontop of that, without a machine definition include file set, there is a lot of work to do just to get to 0
01:22 rue_shop if I use an 8 bit adc
01:22 rue_shop and set a frame length of soemthing like
01:22 rue_shop 384
01:23 rue_shop so the data screen is 384x256
01:23 rue_shop send anything and it captures and transmitts a frame from the next trigger
01:24 rue_shop 384bytes
01:24 rue_shop 1/5 sec @ 19200 baud
01:25 rue_shop maybe if I make a dumb computer program
01:25 rue_shop send '.' and display 384 samples, repeat
01:26 rue_shop the scope would take care of sample rate, and triggering
01:26 rue_shop I should be abel to write that in SDL
01:28 rue_shop the avr code should be easy for that
01:31 rue_shop hmmm maybe I should take all these mcs48 and 8085 baords and stick z80's on them
01:31 rue_shop then I could do all this stuff easy
09:33 fckng_stupid rue, your minimum frame width is the time you can get enough samples with your adc to display a useable signal
09:33 fckng_stupid and ram to put it in
09:34 fckng_stupid if your adc is 500msps, and your ram is 500mbytes, your frame is 1 second long
09:35 fckng_stupid you can then zoom into that and put your display anywhere along it, or keep resetting it (the "sweep") to re-start sooner than one second
10:40 rue_bed I'm implemtnting it different, I'm choosing a screen resolution, and doing a frme from there
10:41 rue_bed but I definitly missed a way for the sytem to tell the computer the division sizes
11:36 SolarNRG What is the best way to get the arm off the tip of a windscreen wiper motor?
11:37 rue_bed lift the release tab
11:37 rue_bed or do you mean the one welded to the motor shaft
11:39 SolarNRG release tab?
11:40 SolarNRG There's a 50mm by 20mm by 4mm thing with two holes in it, one I got off the other is on a screwthread, the other side of that screwthred are 3 plastic gears and the main motor
11:41 rue_bed :) I'd need to see
11:43 SolarNRG www.youtube.com/watch?v=bmgfcSXR6qw
11:43 SolarNRG this is my motor
11:43 rue_bed I cant open that either here
11:43 rue_bed suppose I need to get out of bed
11:46 SolarNRG Have you worked with windscreen wiper motors before?
11:46 rue_bed yea
11:46 rue_bed yours is continious rotaton?
11:47 SolarNRG Yes
11:47 SolarNRG I can make it go both ways
11:47 rue_bed yup
11:47 SolarNRG I'm making an h-bridge for it on tuesday when I got the cash
11:47 SolarNRG I'm trying to get that arm off so I can tap a 35mm pinion gear onto the end of it
11:49 rue_bed how about cutting the arm short enough to bolt the gear to it?
11:49 rue_bed give me a few mins and I'll check the link
11:49 SolarNRG ok
11:50 SolarNRG Is the diamond file the ONLY way to get it off?
11:50 SolarNRG I'm about halfway thru with the diamond file, the hacksaw just blunted on the metal, its too hard for saw
11:50 SolarNRG And I was filing for an hour and a half and I got about 2mm out of 4mm thru
11:50 SolarNRG My hands were knackered
12:00 rue_mohr SolarNRG, hahah
12:00 rue_mohr too excited
12:01 rue_mohr yea that looks welded on
12:02 rue_mohr that should be strong enough yes
12:02 rue_mohr SolarNRG, I sugget a hacksaw
12:02 SolarNRG I tried a hacksaw but it went blunt, that metal is STRONG
12:03 rue_mohr use a hss blade, one of the pricey ones
12:03 SolarNRG can you get diamond coated hacksaw blades and where from in the UK?
12:03 rue_mohr no no, dont need that
12:04 rue_mohr even good steel can be cut by a good blade
12:04 rue_mohr but, leave enough of it on there so you can bolt the gear to it
12:04 rue_mohr cause its attached better than most ways of fixing on a gear
12:20 SolarNRG Also the inside of my 35mm gear is only 5mm
12:20 SolarNRG The thread of the rotor of the windscreen wiper motor is about 10mm
12:20 SolarNRG Don't I need to file it down to a 5mm cylinder so that I can tap it on?
12:20 SolarNRG I'm skeptical about welding in case the plastic gears the other side of it melts
12:21 rue_mohr no dont weld it
12:21 rue_mohr I didn't see a bolt on the end of that shaft with the lever...
12:26 SolarNRG There's a 10mm screwthread
12:26 SolarNRG I've tried to activate the motor and twist it off and I nearly lost my fingers
12:27 rue_mohr yea be carefull on that one
12:27 rue_mohr you want to turn that into a gigantic servo?
12:55 fckng_stupid cut with thin disc in dremel tool
12:57 rue_mohr angle grinder :) if your getting into bigger stuff you r gonna need one eventualy
12:59 fckng_stupid yeas, but the thinner disc will build heat slower
13:00 fckng_stupid those plastic gears on the other end, remember?
13:02 rue_mohr he said there is a nut too
13:02 rue_mohr I'd like a closer photo
13:02 rue_mohr I wonder if its pressed or welded on
13:13 fckng_stupid "you kids stop yelling at each other, use your megaphones"
13:20 rue_mohr :) love it
13:56 Univoid hi all
14:05 rue_mohr hi
15:25 Univoid hi rue
15:26 Univoid rue_mohr, I have bought myself a arduino uno you reckon this will be ok for a first robotic project
15:31 rue_mohr sure
15:35 rue_mohr I saw a circuit baord on my bedroom floor and thought I might be abel to make a state machine out of it, I picked it up and some git already did :)
15:41 rue_mohr i need to make a force sensor
15:41 rue_mohr 147 of them
15:41 rue_mohr no 94 of them
15:47 Big-Al Univoid there is an #arduino chan here also
16:52 rue_mohr whats the ratio of widescreen?
16:52 rue_mohr std is 1.333333
16:53 fckng_stupid a widescreen film is any film image with a width-to-height aspect ratio greater than the standard 1.37:1 Academy aspect ratio provided by 35mm film.
16:53 fckng_stupid For television, the original screen ratio for broadcasts was 4:3 (1.33:1). In the 2000s, 16:9 (1.78:1) TV displays came into wide use.
16:54 fckng_stupid With computer displays, aspect ratios wider than 4:3 are also called widescreen. Widescreen computer displays were previously typically of 16:10 aspect ratio, now they are shifting to 16:9.
16:55 fckng_stupid Widescreen was first used in the film of The Corbett-Fitzsimmons Fight in 1897.
16:55 rue_mohr wondering what ratio to use on the scope, I was gonna go 4:3 but...
16:56 rue_mohr why NOT go wider?
16:56 fckng_stupid well, because *i* have no widescreen anythings
16:56 rue_mohr going 16:9 is 455x256
16:57 fckng_stupid but it's a software issue, if you go wide just truncate the vertical size, if you go 2:3, truncate the width
16:57 rue_mohr its kinda arbitrary really
16:57 rue_mohr vert is 256, I can only see doing 8 bit right now
16:58 rue_mohr maybe I should put a header on the data that gives a bit of info
16:58 rue_mohr vert divisions, horis divisions, and sample depth
16:58 rue_mohr ... and channels?
16:59 rue_mohr I'll make it text, I can expand it later
16:59 fckng_stupid you'll also want color and dynamic markers
16:59 rue_mohr thats all post capture stuff tho
17:00 rue_mohr right now I'm just working on how to get the data from the sample device
17:00 fckng_stupid how you get it has nothing to do with the display
17:00 rue_mohr kinda
17:00 rue_mohr I need a serial protocol for transfering the data
17:01 rue_mohr I'll use a text string prepended to the frame
17:01 fckng_stupid In 2011, Bennie Budler, product manager of IT products at Samsung South Africa, confirmed that monitors capable of 1920x1200 resolutions aren't being manufactured anymore. �It is all about reducing manufacturing costs. The new 16:9 aspect ratio panels are more cost effective to manufacture locally than the previous 16:10 panels�[10]
17:01 rue_mohr thats too bad, the vert res on the wide ones sucks
17:02 fckng_stupid In March 2011 the 16:9 resolution 1920x1080 became the most common used resolution among Steam users. The earlier most common resolution was 1680x1050 (16:10).
17:02 rue_mohr people want 1080 over 1200... stupid...
17:03 rue_mohr so I'll start with a U
17:03 rue_mohr er, no
17:03 rue_mohr [
17:03 rue_mohr then a config information text string
17:04 rue_mohr then ] followed by the data
17:04 fckng_stupid i was watching a widescreen on a 4:3 monitor, and the tops of everyone head was chopped off
17:04 rue_mohr scaled the wrong way :)
17:04 fckng_stupid if it had been shot in 4:3 instead, their entire heads would have been on film
17:05 rue_mohr V n where n is the verical unit size
17:05 rue_mohr H n where n is the horizontal unit
17:05 rue_mohr C n where n is the channel count, default 1
17:05 rue_mohr D n where n is the sample depth, default 8 bit
17:06 rue_mohr S n where n is the sample count, default 455
17:06 rue_mohr the V would need some work, cause you can have multiple channels at different scales
17:07 rue_mohr V n m where n is the channel number and m is the scale ?
17:07 fckng_stupid ok
17:08 rue_mohr I think that allows for enough flexability, being that the computer wont control the scaling or triggering at all
17:10 rue_mohr shoudl I start with the display app or the avr code....
17:10 rue_mohr avr code is easy enough,
17:11 rue_mohr wait for a character from the serial port, sample and transmitt one screen
17:40 Agrgav8d hey, robotics.
17:41 Agrgav8d I've been having a lot of trouble driving my steppers. I've even used an oscilloscope to check the signal and swapped out the steppers. I'm using an arduino to tell a controller to step clockwise once every 0.25s. I do this by sending a HIGH to the step pin, then a LOW 0.125s later.
17:42 Agrgav8d now here's where it gets wierd: the "step" only occurs every second time the HIGH is sent, and the stepper is stepping once CW, once CCW.
17:42 Agrgav8d so what I'm wondering is: have I wired one of the poles backwards?
18:50 rue_mohr Agrgav8d, so I hear
18:51 rue_mohr Agrgav8d, tell me about the driver chip your using
18:56 Tom_itx mmm
18:56 rue_mohr tom! your back!
18:57 m_itx looks behind
18:57 rue_mohr :)
18:57 rue_mohr someone needed a programmer
18:57 rue_mohr pdi er whatever
18:59 Tom_itx where from?
18:59 Tom_itx i got one in my in box
19:00 rue_mohr dunno
19:00 Tom_itx know his name?
19:02 rue_shop nope
19:03 Tom_itx goin thru a week of email
19:16 dunz0r My programmer should be on its way soon.
19:16 nz0r ordered an AVR Dragon from Digikey along with "some" other b
19:16 dunz0r It's hard not to order for insane amounts when they have that much components.
19:17 dunz0r "Maybe I should just get some OR-gates, just in case I need them in the future" etc
20:33 rue_mohr hmm thought I warned you about the dragon, ah well, see how you do
20:34 dunz0r rue_mohr: It wasn't me you warned. But what's wrong with it?
20:34 rue_mohr LOTS of people seem to have problems with them
20:34 fckng_stupid it has a cold, and may sneeze on you
20:35 fckng_stupid copious amounts of snot
20:35 rue_mohr it causes some people to try to buffer and isolate the heck out of them
20:35 dunz0r fckng_stupid: That's ok. I've got a cold too.
20:36 orlok Eh.. i thought i was confused for a moment..
20:36 dunz0r rue_mohr: Hm, hope I won't have to do that then.
20:36 orlok yup, talking about dragons in #robotics, not #nethack
20:36 orlok :)
20:36 dunz0r I'm not going to do anything advanced with it (yet(
20:36 dunz0r If I grow out of it I'll just invest in some other programmer
20:37 lok wonders what sort of serial buffer the arduino
20:38 dunz0r orlok: It's just an atmega328p with some peripherals, so probably what an Atmega328p has :)
20:39 orlok dunz0r: i was thinking specifically about the FTDI interface chip
20:39 dunz0r orlok: Ah. I think it's a FTT232RL
21:38 rue_mohr and when the boiler isn't heating the hosue I can use it to dispose of excess amounts of dirty paper towel
21:39 e_mohr grumbles about cats and me
21:42 fckng_stupid human babies are FAR worse
21:45 thylobot lol
22:29 rue_mohr huh, the isa adc card I made will fit in the z80 motherboard I'm making
22:29 rue_mohr and so will an rs232 serial card
22:29 rue_mohr hmm
22:30 e_mohr excersizes fitting the most projects into completion of a simple task as possable for the purpose of finishing them
22:32 rue_mohr its a good point tho
22:33 rue_mohr if I took an lcd, a small desktop, and some adc's I could mash them togethor into a neato digital scope
22:33 rue_mohr must not lose focus tho
22:34 fckng_stupid i would not use an lcd or a "small desktop"
22:35 fckng_stupid i'd make a way to get the data into a desktop puter , munge it in there, and display it on that puter's monitor
22:35 fckng_stupid alternatively, i'd use the Tektronix plugins and display on any vga monitor
22:35 fckng_stupid but you know i'm fcking_stupid
22:37 fckng_stupid gainsville Fal, someone set a brush fire, caused 2 miles of wreckage on I-75, 10 people dead
22:38 Tom_itx more than that dead due to a captain showboating a ship
22:38 rue_mohr my goal is a bit odd really
22:38 rue_mohr my goal is a digital capture scope
22:38 Tom_itx rue_mohr
22:38 fckng_stupid yeas, i believe robots and Ai would have kept everyone safe
22:38 Tom_itx you're a sparkie
22:38 rue_mohr for capturing servo responces
22:39 Tom_itx https://plus.google.com/photos/111347501166295022626/albums/5660297029718705473/5703265300226446450?banner=pwa&gpsrc=pwrd1#photos/111347501166295022626/albums/5660297029718705473/5703265300226446450
22:39 Tom_itx dicipher that schematic on the side of that switch for me
22:39 rue_mohr I dont mind if the computer dosn't have control over the gain or timebase
22:40 rue_mohr Tom_itx, they put a lamp across one of the contacts
22:40 Tom_itx is it switched?
22:40 rue_mohr switch is middle and left
22:40 Tom_itx is the center common?
22:41 rue_mohr loamp from middle to right
22:41 Tom_itx is the lamp on or off with the switch closed?
22:41 rue_mohr huh
22:41 Tom_itx yeah
22:41 Tom_itx the data sheet says nothing
22:42 rue_mohr I think they mean, tho I'v not seen before, there is a second switch contact for the lamp between the middle and right contact
22:42 Tom_itx http://www.carlingtech.com/pdf/lr_series_lighted_curvette.pdf
22:42 rue_mohr the switch is between middle and left
22:42 rue_mohr the lamp between middle and right
22:43 rue_mohr middle goes to hot, right to neutral, left to load
22:43 rue_mohr oh Tom_itx }:) I got my industrial thermal controller talking rs232
22:43 Tom_itx cool
22:44 rue_mohr now I have full and complete control over my toasteroven }:)
22:44 Tom_itx figure out all the commands?
22:44 rue_mohr AND I have a new toaster oven
22:44 Tom_itx good
22:44 rue_mohr I ahve the datasheet
22:44 Tom_itx bonus
22:44 rue_mohr I can do all the ramping and soaking I want under pc control
22:44 Tom_itx i think i'm goin to sleep really soon. i drove 10 hrs today
22:45 Tom_itx well I made it a 9 hr trip
22:46 Tom_itx email says my boards are waiting for me at the post office
22:46 Tom_itx hope they didn't send em back
22:46 rue_mohr I wonder what I did with the scope software I made for this ISA card...
23:07 rue_mohr kat, an interesting idea would be to have a dig scope take a min and max reading at each sample, that way, you wouldn't get aliasing
23:07 fckng_stupid reading of what?
23:07 rue_mohr the input wav
23:07 fckng_stupid volts? freq? slew rate? type of waveform? what?
23:08 rue_mohr you would have two peak followers, that had the same responce time as the sample period
23:08 fckng_stupid new dig scopes have a lot of software in them
23:08 fckng_stupid iirc, the Tek scopes on the used market today run winxp
23:08 rue_mohr you would read the high and low peak for each sample, and display it as a verticle line, if its within freq of the scope, it would just be one pixel
23:09 rue_mohr hmm
23:09 fckng_stupid one pixel? seriously? so a square wave is only one pixel wide?
23:09 rue_mohr non aliasing digital scope, hmmm
23:09 rue_mohr sorry, your not understanding what I'm talking about, thats ok
23:10 rue_mohr basically each sample would be a range of the voltage within that sample period, not just a single voltage reading
23:11 fckng_stupid so it has a peak reading dvm, ok
23:11 rue_mohr nope
23:12 rue_mohr instead of each adc sample being a instantanious voltage, it would be an sample period range
23:12 fckng_stupid it's digital, it's a voltmeter, it reads the peak high and low,, it's a peak-reading dvm
23:12 theBear no, in the case of a very high freq wave it will read 50% and no high or low
23:13 fckng_stupid your adc IS an instantaneous reading, it spits out ONE reading
23:13 theBear how do you think it gets that reading ?
23:13 rue_mohr theBear, better yet, the data stream is from two adc's one high and one low
23:13 rue_mohr if your within the scopes freq, they are the same
23:13 theBear incharresting
23:14 fckng_stupid why two? you can s&h with analog and take two adc readings with one adc chip
23:14 rue_mohr if your over it, they differ to the max/min voltage of that period, so the scope can draw a vert line for that sample
23:14 theBear in a digital scope you are already pushing the adc as fast as it will go, you don't multiplex it
23:14 rue_mohr meaning it acts like an analog scope, and will not alias
23:14 rue_mohr two adc's
23:15 fckng_stupid bear, not at the low freqs rue is talking about, he is sampling audio at 20mhz
23:15 rue_mohr the most palusable adc I have right now is 1msps
23:15 fckng_stupid the Tek 11000 series muxes a 1gsps adc chip
23:15 theBear you don't multiplex it, most adcs go on a progressive approximation kinda concept, you just don't multiplex it
23:16 kng_stupid has ~300 flash adc, 20mhz 8 and 10
23:16 theBear ang on
23:17 theBear ah ffs, i can't talk to you when yer called that, it's like a different person
23:17 theBear plus i forget
23:17 rue_mohr kat, pls put your proper name tag on!
23:17 Tom_itx yeah
23:18 theBear you get former-knowledge-credit when you are you, when i don't recognise you i can't just assume you know shit
23:18 Tom_itx no
23:18 Tom_itx not that one
23:18 eBear wanders
23:18 rue_mohr !assist images/scope.png
23:18 tobbor Possibly http://eds.dyndns.org/~ircjunk/images/scope.png
23:18 rue_mohr what do you think so far?
23:19 rue_mohr what did she do, I cant see
23:19 Tom_itx it's a wiggly line
23:19 katsmeow you already have the scope working?
23:19 rue_mohr kat!
23:19 e_mohr hugs katsm
23:19 rue_mohr you fixed my tab completion!
23:19 rue_mohr yes, its a wiggly line
23:19 Tom_itx i'm goin to sleep now
23:19 rue_mohr with a really light grey grid
23:20 rue_mohr that line is gonna come from an avr soon
23:20 rue_mohr soon ~ a month
23:20 Tom_itx can't see the grid
23:22 rue_mohr 1 sec...
23:23 rue_mohr frefresh

23:23 zhanx the word robot was coined in 1920 by Karel Čapek
23:24 rue_mohr before that it meant slave no?
23:24 theBear nah, it was a dance
23:24 rue_mohr zhanx, pls help make suggestions for my digital scope app
23:24 rue_mohr hahah
23:24 zhanx robotics was coined in 1942 by science fiction writer Isaac Asimov
23:24 rue_mohr we made machines to mimic it?
23:24 zhanx and yes it meant serf in czech
23:25 zhanx 4 channels and a usb interface
23:25 zhanx for data logging
23:25 e_mohr shudd
23:25 rue_mohr its rs232, use an adapter
23:25 zhanx k
23:26 rue_mohr the protocol is [configuration string]data
23:26 rue_mohr where the [ and ] are literal, the data is binary
23:26 zhanx cool
23:27 rue_mohr the config string is modular, with codes for what the scales and times are
23:27 rue_mohr sending a character to the unit causes it to barf its next set of triggered data
23:28 rue_mohr default is 455 8 bit samples (16:9 ratio)
23:28 zhanx more important hack it out of a modem
23:28 rue_mohr haha
23:29 rue_mohr ... that might be plausable for an 8031 based modem.....
23:29 rue_mohr *blink*
23:29 rue_mohr no, wait, I have an HP input module I'm gonna use for it
23:29 rue_mohr no distracting me
23:30 zhanx or....
23:30 rue_mohr I'm gonna start with just a plain avr
23:30 zhanx ISA card for scsi drivers
23:30 rue_mohr hu?
23:31 rue_mohr no no no, I'm gonna make this a serial device!
23:31 rue_mohr yer tryin to distract me....
23:31 rue_mohr I'm gonna stick a serial backend on this gui code and get programming the avr...
23:31 zhanx maybe.. but it would be sweet to see an old scsi card hacker for more life
23:32 rue_mohr but I could just use a pci scsi for scsi 1 and hook it to 2 8 bit adc's to get two simotaneous channels
23:33 rue_mohr tho I could do the same thing with an ide interface
23:34 rue_mohr imagine what I could do if I tore the differential interface off a new scsi drive and hooked the adc's to that, I could plug it into any new scsi channel
23:34 rue_mohr nonono cut that out!
23:34 rue_mohr your gonna have me at usb3 in 10 mins at this rate
23:35 zhanx lol
23:35 zhanx brb
23:36 e_mohr leans over to keep half an eye on z and make sure he's not building a usb3 dig s
23:43 rue_mohr ok, display verticle zeroing would be nice
23:45 zhanx nope using the bathroom, not something you want to watch
23:52 katsmeow no one wanted to watch, we wondered if the process could be connected to a oscope
