Back
[00:00:26] <rue_shop3> the microcontroller would be slow
[00:00:39] <katsmeow> i don't think i'd use 20msps for much above 200Khz, if you want a faithful pic
[00:00:41] <rue_shop3> so I'd want the system to grab a frame at a time
[00:00:53] <rue_shop3> well, I dont need a fast scope
[00:01:03] <rue_shop3> I need to capture servo response curves
[00:01:23] * katsmeow nods
[00:01:52] <rue_shop3> I'll prolly do with a 1msps maxim chip first
[00:02:30] <rue_shop3> do you know what your adcs dump info?
[00:02:33] <rue_shop3> into?
[00:02:36] <rue_shop3> an fpga?
[00:02:39] <rue_shop3> asic?
[00:03:02] <katsmeow> i didn't trace it
[00:04:16] <rue_shop3> a 6 bit flash adc must be used for video capture..
[00:06:07] <__m00n__> ip phone ?
[00:06:22] <rue_shop3> bedtime is 9:45 dude
[00:06:27] <katsmeow> why 6bit?
[00:06:38] <rue_shop3> R G or B
[00:06:48] <katsmeow> why 6bit?
[00:06:51] <rue_shop3> 6*3 = ...
[00:07:05] <rue_shop3> seems to be what they use for digitized composite
[00:07:26] <katsmeow> do the math, rue
[00:07:42] <rue_shop3> I tried
[00:07:53] <katsmeow> 3x 2^6 = 262,144 colors
[00:07:54] <rue_shop3> 18 bits
[00:08:03] <rue_shop3> 256k
[00:08:46] <katsmeow> ok, for ntsc color, not good nuff for the luma, been there, done that
[00:08:51] <rue_shop3> all the adc's for arduinos put on baords peak out at 800ksps
[00:09:00] <katsmeow> need 8bit for luma, even for ntsc/pal/secam
[00:09:13] <rue_shop3> they usually decode it into r g b and steam the 18 bits
[00:09:21] <katsmeow> arduino is not hifi video
[00:09:21] <rue_shop3> I'm sure of it
[00:09:25] <rue_shop3> no
[00:09:34] <rue_shop3> nobody made a helper board
[00:10:44] <rue_shop3> $22 for an arduino oscilloscope :/
[00:11:38] <rue_shop3> BW = 200khz
[00:12:03] <katsmeow> i got 300 pcs of 20msps@10bit adc for $free , hell with $22
[00:12:21] <katsmeow> i got 140msps chips too
[00:14:03] <katsmeow> people were outside walking tonite about sundown, something i have not seen in ~15 yrs here
[00:14:33] <katsmeow> an adult + kids, several groups, no one carrying rifles, no gods barking or threatening them
[00:15:22] <katsmeow> all was quiet and peaceful, as if all the gods were gone, and no aholes speeding on atvs
[00:15:22] <rue_shop3> tv service went out maybe
[00:15:58] <katsmeow> rue, anyne in the streets here for the last decade was fair game for a god mauling
[00:16:07] <katsmeow> and it happened
[00:16:36] <rue_shop3> $30 for me seems reasonable for a little dig scope
[00:16:46] <rue_shop3> they say 1msps
[00:17:42] <katsmeow> but you get no teaking knobs like on a 5A14 or a 7a26 or 7A22
[00:17:47] <katsmeow> tWeaking

[00:19:27] <katsmeow> they on ebay too, have been for years
[00:22:20] <rue_shop3> oh its got an arm processor
[00:22:28] <rue_shop3> that explains the 1msps and the 12 bit
[00:24:35] <katsmeow> http://www.ebay.com/sch/i.html?_odkw=arduino+digital+scope&mfe=search&clk_rvr_id=1051266381684&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR0.TRC0.H0.TRS0&_nkw=arduino+digital+Oscilloscope&_sacat=0
[00:24:46] <katsmeow> some 20Mhz sacopes
[00:25:49] <rue_shop3> remember, the usa and canada blow it in shipping costs
[00:25:53] <katsmeow> $18 : 20Mhz (200khz analog ) : http://www.ebay.com/itm/Digital-Oscilloscope-0-200KHz-Analog-Bandwidth-1Msps-2-4-LCD-TFT/291337112783?_trksid=p2045573.c100034.m2102&_trkparms=aid%3D555012%26algo%3DPW.MBE%26ao%3D2%26asc%3D36866%26meid%3D653ff44bb6814c28a2e707203403e5b3%26pid%3D100034%26rk%3D1%26rkt%3D8%26mehot%3Dpp%26sd%3D221949762450

[00:26:59] <rue_shop3> :(
[00:26:59] <katsmeow> free s&h
[00:27:32] <katsmeow> remember, they had to pull tricks to get digital in the 60's and 70's
[00:28:23] <rue_shop3> http://www.ebay.com/itm/TEKTRONIX-2221A-DIGITAL-STORAGE-OSCILLOSCOPE-/391488820792
[00:28:25] <rue_shop3> arg
[00:28:51] <rue_shop3> (its just got a minor deflection prob too)
[00:28:53] <zhanx> 1 am junior is out, I am in trouble
[00:29:19] <rue_shop3> zhanx, buy me that scope and walk it to me!
[00:29:29] <katsmeow> SOLD AS-IS, PLEASE NOTE UNIT MAY BE SLIGHTLY DIFFERENT FROM PICTURE"
[00:29:41] <rue_shop3> hmm
[00:29:45] <rue_shop3> with broken knobs
[00:29:47] <rue_shop3> :/
[00:30:02] <rue_shop3> AAAAAAAAAA they keep comming up for $25
[00:30:03] <katsmeow> read the manual, you got 9 hrs to bid
[00:30:18] <rue_shop3> it wont ship for a reasonable cost
[00:30:31] * rue_shop3 cries
[00:31:00] <katsmeow> for $75 for a 250Mhz digital scope that works, $300 is reasonable s&h
[00:32:27] <rue_shop3> unless it arrives like yours did
[00:32:31] <katsmeow> $240 for a 250Mhx workhorse : http://www.ebay.com/itm/Tektronix-475-200MHz-Dual-Channel-Oscilloscope-w-Power-Cord-Manuals-and-Extras/322163145557
[00:32:37] <rue_shop3> whats the 2201
[00:32:40] <rue_shop3> 22Mhz?
[00:32:53] <rue_shop3> no, 2 channel, 200Mhz?
[00:33:06] <rue_shop3> 2 channel 20Mhz, 1... something?
[00:34:22] <katsmeow> Tektronix 2201= [!what][!electronic device] scope, 20MHz dual DSO
[00:34:44] <rue_shop3> hmm, my existing scope is 20Mhz
[00:35:07] <rue_shop3> oh, sorry, its 25Mhz
[00:35:35] <rue_shop3> I have the 7A18 module for making a scope with tho
[00:35:40] <rue_shop3> for making a digital
[00:36:07] <rue_shop3> also have a 5A18
[00:36:14] <katsmeow> the '18 is good for 75Mhz analog
[00:37:02] <rue_shop3> mmmm
[00:37:53] <rue_shop3> I have a 5A21
[00:38:12] <rue_shop3> and some other junk, I got a grab box of modules from ebay, all 5A
[00:38:19] <katsmeow> Tektronix 5A21N= [!what][!electronic device] differential/current probe amp 1MHz
[00:38:24] <rue_shop3> I have the 7A as the 'good one'
[00:38:50] <katsmeow> Tiggr knows this stuff
[00:42:54] <katsmeow> don't get the 2236, the digital meter is seldom correct
[00:43:14] <katsmeow> and i have a 2235, i would not recommend it because my psu fried
[00:44:28] <katsmeow> i ast a Tek rep down with a 2236 and gave him a video signal and told him to make the meter tell me what it's chroma burst freq was, it never got it right
[00:52:33] <rue_house> I dont want to eat
[00:52:37] <rue_house> this is not helping
[00:56:15] <rue_house> zhanx,
[00:57:18] <katsmeow> he's over there =====>>
[00:57:44] <rue_house> zhanx, http://ruemohr.org/~ircjunk/robots/armcontroller/slide.htm
[01:04:19] <rue_house> http://ruemohr.org/~ircjunk/robots/armcontroller/m328capture.tgz
[01:04:28] <rue_house> check the last image, I just added it
[01:08:02] <rue_house> ok where do I put the next part
[01:12:23] * katsmeow waves gnites
[01:12:48] <rue_house> gnight
[01:13:04] <rue_house> zhanx, the software that records motion is not the same one that plays it back
[01:13:18] <rue_house> but it does do realtime control, recording is like a side-feature
[01:16:59] <rue_house> http://ruemohr.org/~ircjunk/robots/armcontroller/robotracker.tgz
[01:17:06] <rue_house> its an evolved mess tho
[01:17:46] <rue_house> all thats missing is the firmware that recieves the position stream, but my only working version of that right now is for hobby servos
[01:18:09] <rue_house> tho it should be compatible with the 4 channel loop controller...
[21:45:42] <katsmeow> rue, ye has e-mail
[22:48:26] <katsmeow-afk> .
[22:57:56] <zhanx> Downloading
[22:59:31] <katsmeow-afk> sitting
[23:03:07] <rue_bed> zhanx, did you get the links?
[23:03:20] * rue_bed wakes up
[23:03:27] <zhanx> Yes
[23:03:47] <rue_bed> wow 8:30pm
[23:03:59] <zhanx> 2337
[23:04:01] <rue_bed> zhanx, did you download it incase the internet explodes?
[23:04:09] <zhanx> Yes
[23:04:13] <rue_bed> ok
[23:04:40] <zhanx> I heard Canada wants Alaska
[23:04:46] <rue_bed> the comments in the m328 software are all wrong cause I built it from anothe project and then ported it
[23:04:51] <rue_bed> hah
[23:05:08] <rue_bed> then we can ditch quebec and not get smaller
[23:05:13] <zhanx> They are willing to trade equal land in southern Canada for it
[23:05:25] <rue_bed> if the usa thinks they want them, go for it
[23:05:25] <katsmeow-afk> the oil sands?
[23:05:30] <zhanx> To make Maps easier
[23:06:01] <rue_bed> europe is apparently trying to reshape itself
[23:06:14] <rue_bed> and failing with a 5% margin
[23:06:41] <zhanx> The eu is failing due to lack of real over sight, the issue is ww3
[23:06:52] <rue_bed> if the usa can fake electrion results by over 20%, how did europe fail to do it by 5?
[23:07:41] <zhanx> Canada unfortunately won't be able to sit this one out
[23:07:56] <rue_bed> I think even canada was able to fake election results by about 15%
[23:08:27] <rue_bed> wait wait, would adding alaska make us larger than russia?
[23:08:32] <zhanx> Heck look at California, they did 30% or mkre
[23:08:36] <katsmeow-afk> but Canadai isn't part of theEu
[23:08:56] <rue_bed> just wait, canada is like 60% china owned
[23:09:04] <rue_bed> 20% usa owned
[23:09:27] <rue_bed> we know canadians have atleast 6%
[23:09:34] <katsmeow-afk> but Canadia didn't have the forced slave labor to develop the north like ussr did/does
[23:09:48] <rue_bed> we dont have the population either eh?
[23:09:52] <zhanx> Marked I said it ww3 is coming
[23:10:11] <rue_bed> !bookmark zhanx says ww3
[23:10:22] <katsmeow-afk> wasn't diagreeing with you, just a matter of hot long and hot is is
[23:10:38] <zhanx> 8-11 months it starts
[23:10:44] <rue_bed> <parse fault>
[23:10:52] <rue_bed> over alaska?
[23:11:01] <rue_bed> a bunch of eskimos?
[23:11:04] <zhanx> Over trade
[23:11:11] <katsmeow-afk> no, middle east and usa trespassing everywhere
[23:11:33] <zhanx> Eu immigration laws
[23:11:42] <rue_bed> we are canadian, we dont fight, we take it up the ass
[23:12:14] <zhanx> You apologize while doing it
[23:12:27] <rue_bed> yea, and you know why? were CANADIAN
[23:12:49] <katsmeow-afk> still are canadian
[23:12:53] <zhanx> So say sorry and give us, Vancouver
[23:13:05] <rue_bed> look for the song 'far too canadian'
[23:13:28] <rue_bed> zhanx, learn your history, you dont want it
[23:13:46] <rue_bed> did you hear vancouver island wants to be its own province?
[23:13:48] <katsmeow-afk> prolly take Quebec, since it borders on Hudson Bay
[23:13:55] <rue_bed> talk about political garbage
[23:14:08] <zhanx> Oh haven't you learned the us can mess up the worst place
[23:14:15] <rue_bed> not even canada wants quebec
[23:14:32] <zhanx> The bc then?
[23:14:54] <rue_bed> bc is prettymuch the us anyhow
[23:15:06] * katsmeow-afk apologises
[23:15:28] <rue_bed> just yesterday we had a conversation about if canada has to lose the canadian dollar and use the us dollar
[23:15:44] <zhanx> Ok
[23:15:48] <rue_bed> and I was pointing out that everything we buy is in us dollars anyhow
[23:16:10] <zhanx> Oil prices ?
[23:16:15] <rue_bed> were not ontario
[23:16:28] <rue_bed> we dont get jack **** out here
[23:16:36] <katsmeow-afk> but the usa is in a debt hole it will never climb out of, you sure you want usa dollars?
[23:16:51] <zhanx> Thanks obama
[23:16:55] <rue_bed> the world uses us dollars
[23:17:13] <katsmeow-afk> not my fault
[23:17:17] <rue_bed> imagine the reprocussions when rome fell
[23:17:21] <rue_bed> fanancially
[23:18:06] <rue_bed> the usa is going rotten from the inside out, there may seem to be a strong political prescence, but its losing real backing
[23:18:31] <rue_bed> the usa is not bankrupt right now because of money injection from places like china
[23:18:43] <katsmeow-afk> rue, didya see the stunt in the congress 2 nights ago?
[23:19:04] <rue_bed> its not obamas fault, with the minority he had, nobody would let him do anything for the sake or not letting him do anything
[23:19:26] <zhanx> He had a majority at the start fyi
[23:19:31] <rue_bed> what happened? about obamas endorements?
[23:19:50] <katsmeow-afk> parse fault
[23:19:56] <katsmeow-afk> what's an endorement?
[23:20:00] <rue_bed> candidate endorsement
[23:20:05] <katsmeow-afk> o
[23:20:11] <rue_bed> this laptp is really hard to tyrpe on
[23:20:20] <rue_bed> I only fixed that twice
[23:20:30] <katsmeow-afk> i think Obama doesn't wanna upset Bernie
[23:20:44] <zhanx> Obama gave 1.2 billion to a friend's business, that failed and was sold to china
[23:20:56] <katsmeow-afk> so he cannot endorse Clinton fully until Bernie quits running
[23:20:58] <rue_bed> hah
[23:21:24] <rue_bed> isn't whatshisfutz winning?
[23:21:32] <rue_bed> tea
[23:21:34] <rue_bed> I need tea
[23:21:38] <rue_bed> I forget this
[23:21:56] <zhanx> The exchange for health care to his wife's college buddy, 18 million
[23:21:57] <rue_bed> kat, I need to know the processing structure of the brain
[23:22:19] <katsmeow-afk> "make these links or no desert"
[23:22:21] <rue_bed> they would not let him do anything
[23:22:35] <rue_bed> after 2 years you could see it in his face
[23:22:48] <rue_bed> he realized that the president is just a puppet
[23:22:50] <katsmeow-afk> and he got white hair
[23:23:15] <zhanx> And the first two years he had a democratic congress
[23:23:27] <rue_bed> I think he really beleived that being president would give him the power to fix things
[23:23:44] <zhanx> Transparencies
[23:24:18] <zhanx> Most transparent presid ever with the most foia files ever
[23:24:20] <rue_bed> no president can fix the usa
[23:24:34] <rue_bed> they can just be the face on the derailing train
[23:24:59] <zhanx> He blocked more foia, than anyone
[23:25:16] <rue_bed> no wars!
[23:25:30] <katsmeow-afk> lol
[23:25:34] <zhanx> Libya, sirya, yeman
[23:25:34] <rue_bed> I'm sure the next prez will make sure to set up a good money making war
[23:25:53] <rue_bed> hi zack
[23:26:04] <katsmeow-afk> cannot be with Iran, they just signed to buy $billions of Boeing jets
[23:26:12] <rue_bed> rue_shop3, hows it goin?
[23:26:15] <zhanx> I sure all those proxy wars count as zero
[23:26:34] <rue_bed> zhanx, its about how much money moves
[23:26:42] <rue_shop3> :P
[23:26:52] <zhanx> True and they moved billions
[23:27:19] <zhanx> But only a selection of us personal died
[23:28:42] <zhanx> Rue on this one I have insider information :)
[23:33:43] * katsmeow-afk sent rue some of a dream she had, so it can be made into a tv series in Van, where all the great tv series are made now
[23:33:55] <katsmeow-afk> naturally, rue has not replied
