[00:22:38] <rue_house> or not
[00:23:14] * katsmeow noticed
[00:30:37] <rue_house> hey
[00:36:56] <katsmeow> ?
[00:40:21] <rue_house> well I better day something before the night is out
[00:43:47] <rue_house> still having problems figuring out what serial method to use to push data from the adc chip
[00:44:02] <rue_house> mainly cause my main controller is down the uart I want to use
[00:48:29] <katsmeow> parse error
[00:50:01] <rue_house> so I'm using a tiny26 as an adc
[00:50:18] <rue_house> because its got 11x 10bit channels, for about $2.60
[00:50:25] <rue_house> which is cheaper than any adc
[00:50:30] <katsmeow> de ja vu
[00:50:34] <rue_house> ...might cost less,. anyhow
[00:50:54] <rue_house> I need to come up with a low-latency serial proto for it to the main controller that does the feedback loop control
[00:51:13] <rue_house> the options are not playing out nicely
[00:51:59] <rue_house> I dont want a protocol that requires the channels to be manually read, I want them to steam in a timely manner
[00:52:01] <rue_house> like a T1
[00:52:21] <rue_house> not fast, but low or fixed latency
[00:52:28] <katsmeow> use ecl, turn the chips on only as necessary, blast the data out @800Mbits
[00:52:52] <rue_house> the loop controller will probabyl be a 8051
[00:53:13] <rue_house> for an interm project, its an atmega 8
[00:53:33] <katsmeow> then you are stuck with the problems you have
[00:54:32] <katsmeow> you cannot keep doing it the way you have been, and get 50x better results
[00:56:05] <rue_house> the design I like so far is that the adc is the bus master and shifts the data out as if into a 74xx595
[00:56:31] <katsmeow> use ribbon cable at 100Mbits , 8 or 10 or 12 bit parallel and ttl differential
[00:56:32] <rue_house> which might be a good method for the 8051 interface
[00:56:40] <rue_house> needs to be serial
[00:56:49] <katsmeow> then ecl
[00:56:53] <rue_house> the tiny26 dosn't have enough pins otherwise
[00:56:59] <katsmeow> ttl tops out at 100Mhz
[00:57:07] <rue_house> it dosn't have to be fast
[00:57:15] <rue_house> 300sps/channel x 11 channels
[00:57:30] <rue_house> 16 bits/sample frame (id + sample)
[00:57:30] <katsmeow> serial fast = low latency moving bytes of data
[00:58:09] <rue_house> fixed latency is ok too
[00:58:27] <rue_house> it IS a digital loop controller
[00:58:31] <katsmeow> we discussed this before, many times, i give up
[00:58:58] <rue_house> I'm mulling between options
[01:01:50] <katsmeow> clock it outa the adc as fast as it goes, into a ttl shift register, then burp the shift register out to the master 50Mhz
[01:03:43] <katsmeow> it will take longer to get the data outa the adc than to move it upstream on the ttl
[01:06:26] <rue_house> yup
[01:06:39] <rue_house> the adc on the tiny26 isn't blazing fast
[01:06:54] <rue_house> but I'm aiming for a loop update time of 150Hz
[01:07:06] <rue_house> I think that will be fast enough
[01:07:45] <rue_house> hehe "Fuqiang electronic"
[01:07:52] <rue_house> (china seller)
[01:08:08] <rue_house> http://www.aliexpress.com/item/S-terminal-9-p-and-head-connector-PS2-and-9-p-9-mini-DIN-full-copper/793549032.html
[01:08:33] <rue_house> that is the ONLY instance of that connector I can find, its a din, 9p with the spaced pins on the row of 4, not the row of 3
[01:09:12] <rue_house> I need one, and the pins on the back need to fit into a pcb, which those ones dont look like they will
[01:10:51] <katsmeow> if you use an item that only one oem has, they'll quit making it, you cannot get any more
[01:18:53] <rue_house> I'm stocking up
[01:19:14] <rue_house> by far its the cheapest thing to use as a multichannel adc
[01:20:32] <rue_house> say ~$1.40/chip
[01:20:38] <katsmeow> wait, you are using this connector as a socket for the tiny?
[01:20:47] <rue_house> 13c per channel
[01:20:58] <rue_house> no, two seperate things going on
[01:21:09] <rue_house> the connector is for fixing a hospital drain camera
[22:35:35] <zhanx> Evening and kat change your name back
[22:40:23] <rue_shop3> ?
[22:44:51] <zhanx> Idonob_
[23:00:23] <rue_shop3> erm, I dont think thats kat
[23:00:47] <zhanx> Oh
[23:01:17] <zhanx> Setting up a new hacking lab fyi
[23:01:32] <rue_shop3> k
[23:02:24] <rue_shop3> got a good name?
[23:02:24] <zhanx> Got off the va drugs. While o was gone etc . Got 14 cordless drills minus the battery packs
[23:02:52] <zhanx> No I suck at naming stuff
[23:03:01] <rue_shop3> me 2
[23:03:27] <zhanx> I will never forget a face but a name yea what did you say
[23:03:54] <rue_shop3> ditto, i hate oblivious people
[23:04:00] <rue_shop3> HEY!
[23:04:23] <zhanx> Welder needed !
[23:04:42] <rue_shop3> i once met someone who just called everyone fred
[23:04:50] <zhanx> Wait I got one now
[23:05:04] <zhanx> Still need an air compressor
[23:05:05] <rue_shop3> i was amused when i caught on
[23:06:03] <zhanx> Oh did I tell you my tiger barb fish had babies?
[23:06:21] <rue_shop3> nope
[23:06:44] <zhanx> Got 2 baby tiger barbs 1/4" long
[23:07:07] <zhanx> Tiny happy things
[23:07:16] <rue_shop3> rifraf had goldfish and sharks, the goldfish ate the sharks, thats how intense australia is
[23:07:28] <zhanx> Wow
[23:08:03] <zhanx> I rest my case, can not compare to that
[23:08:30] <rue_shop3> if i had to choose fighting an aussie or a scott id prolly just do myself in
[23:08:48] <zhanx> I would take the both
[23:09:43] <zhanx> A. Aussie, b Scott, c, you, d. A&B
[23:10:04] <rue_shop3> I was gonna say that after a pounding a scott might take you out for a drink, but the aussie might too
[23:10:22] <zhanx> They both would
[23:10:55] <zhanx> So off topic
[23:11:12] <zhanx> Did rear breaks on my van
[23:11:37] <zhanx> I couldn't break the lugs nuts lose
[23:11:46] <rue_shop3> I have to *slightly* grind down all 1000 leds for my led scope, I'm not at the 25% mark yet
[23:11:58] <rue_shop3> sheered them?
[23:12:32] <zhanx> Break job was a "fun" job
[23:12:44] <zhanx> New wheel bearings etc
[23:13:04] <zhanx> And got rained on
[23:13:51] <rue_shop3> hows work
[23:13:51] <rue_shop3> ?
[23:14:21] <zhanx> Long story short, I got fired
[23:14:27] <rue_shop3> huh
[23:14:44] <rue_shop3> sounded like he was avoiding that
[23:14:57] <zhanx> Va was experimenting with my drugs
[23:15:36] <zhanx> Found out I was taking non fda approved stuff that made me worse
[23:16:27] <zhanx> All done now, I got 2 pages of blue prints now
[23:17:19] <rue_shop3> can you sue him?
[23:17:24] <zhanx> Remember that robot from you tube you showed me that could not be built? The bird thing
[23:17:25] <rue_shop3> you need income after all
[23:17:48] <zhanx> I have income
[23:18:13] <rue_shop3> ok
[23:18:57] <zhanx> You didn't answer my question
[23:19:11] <rue_shop3> I dont recall a bird thing
[23:19:52] <zhanx> It was a multi joint robot thing looked like a bird to me
[23:20:02] <zhanx> Danced around
[23:20:13] <rue_shop3> nothing clicking
[23:21:07] <zhanx> K. I need to finish my work and get sleep. Will find it tomorrow. I am making something weird even for me
