00:23 katsmeow-afk LM318, 78xx , 79xx , TL431 , etc
00:25 rue_house hey 1 I think tl431 is what I was looking fro
00:25 katsmeow-afk i got to thinking, which is usually a dangerous thing, considering my truck is not the only one expereinceing identical fuel issues, and rewired the front fuel pump (which useto be the rear fuel pump), and the truck runs much better now
00:26 katsmeow-afk prolly is, TL431 is one of thos lil things that does a fine job at what it does
00:27 katsmeow-afk as usual, get the OnSemi datasheet for it
00:32 katsmeow-afk in the classic transistor-2-diode-resistor curent source, the TL431 replaces the two diodes for *much* better stability, and it's a *hugely* better zener too
00:33 katsmeow-afk NXP and Fairchild, and prolly 100 otehr oem make it
00:34 tsmeow-afk just watched Obli

00:40 katsmeow-afk WASHINGTON -- The Obama administration has opened a small, but potentially important, hole in a key requirement of the new healthcare law, letting some people who have had insurance policies cancelled avoid the requirement to buy coverage next year.
00:44 katsmeow-afk Even the Farmers' Almanac hedged its bet. "But even if we are off by a day or two with the timing of copious wind, rain and snow, we wish to stress that this particular part of the winter season will be particularly volatile and especially turbulent," it said.
00:55 katsmeow-afk "Mr president, Kim Jung Ill is calling, wants to send xmas presents to all the children of our military service members, and is asking for their "ICBM addresses" ?"
00:59 katsmeow-afk just think, when the two new fuel pumps get here, it will be freezing outside again, and i'll prolly be back up under the truck again
01:18 katsmeow-afk how to draw a straight line down a length of pipe: lay it in some steel angle that's laying around, use a chain-visegrip or rubber bands or human helper to keep it from turning, use one edge of angle as the straightedge
09:15 rue_house its snwoing its snowing
17:58 tsmeow-afk wants to know why she has no en
17:59 katsmeow-afk oh,, ok, i cauht the flu from the tow truck driver
18:00 rue_house hmm tow truck, that dosn't sound like a good story
18:00 tsmeow-afk wonders where rue has been, the tow truck was days
18:00 rue_house at work
18:01 rue_house I work from (effectivly) 7:20am to 5pm
18:01 katsmeow-afk you were here in channel when i was discussing it with Tom days ago
18:01 rue_house weekend or after work?
18:02 rue_house :) or me dipping in for lunch
18:02 katsmeow-afk .. 1 pm Tuesday 12/17/2013 ..
18:02 katsmeow-afk [13:29] <katsmeow-afk> well, i am back home after 3.5 hrs gone and a $100 tow bill
18:02 katsmeow-afk [13:30] <katsmeow-afk> half a tank of fuel and the pump can't get it out of the tank
18:02 rue_house oh damn
18:02 rue_house thats why you were on about fuel pumps?
18:02 katsmeow-afk ...............
18:02 katsmeow-afk [19:15] <katsmeow-afk> i wonder if the local fuel supply is containated with soemthing that gasifies out to form bubbles
18:02 katsmeow-afk [19:37] <rue_mohr2> I got ebay things!
18:02 rue_house I thought it was something tom was up to
18:03 rue_house ' <rue_mohr2> I got ebay things!' means I just got home
18:03 Tom_itx code?
18:04 rue_house code?
18:06 katsmeow-afk code?
18:07 Tom_itx code?
18:08 Tom_itx is that code for 'rue_house is home'?
18:09 rue_house I check the mail on my way in from work
18:09 katsmeow-afk C:\WINDOWS\system32>rue_house is home
18:09 katsmeow-afk 'rue_house' is not recognized as an internal or external command,
18:09 katsmeow-afk operable program or batch file.
18:09 rue_house there is the proof, I'm inoperable
18:10 katsmeow-afk needs different 'drivers', Miss Daisey
18:15 katsmeow-afk lotta antihistamines out there, what about some prohistamines?
18:16 Tom_itx damn protesters
18:16 any05022373 wth
18:18 katsmeow Tom, what protestors?
18:18 Tom_itx anti-histamines
18:19 katsmeow o
18:20 rue_house interesting, I need to find a 32.000Khz resonator to make a 1ms ref
18:20 katsmeow very intersting
18:21 rue_house aka, I cant do it witha 32.768 watch crystal
18:21 katsmeow you could make a 1ms ref with any freq of a 1khz increment
18:21 katsmeow erll,, you *could*, but it would need a few more chips
18:24 rue_house if...
18:25 rue_house if this code does the timing in 1ms resolution
18:25 rue_house and
18:25 rue_house is the max time between knocks is 1200ms
18:25 rue_house and that is scaled down to 0-100
18:25 rue_house why does this system use 1ms?
18:26 katsmeow you should have xtals, each cable box i got has at least 3, and some have 9, all different
18:26 rue_house hmm
18:27 rue_house have any 32.000kHz wee ones?
18:28 katsmeow i didn't bother to remember them, or write them down, but there were some like 5.000Mhz
18:28 tsmeow checks something......
18:29 katsmeow yeas, i did write down i have qty 3000 of 30Mhz precision osc cans
18:29 rue_house kHz

18:30 katsmeow yeas, i know what the 32khz round ones look like
18:30 katsmeow but i know those are not in the cable boxes
18:30 rue_house you SURE!?
18:30 katsmeow prolly not int he radios either
18:30 rue_house usualyl in anything with an RTC
18:31 tsmeow hands rue one of his own dead puter
18:31 rue_house http://www.aliexpress.com/item/Free-Shipping-100PCS-DIP-passive-crystal-Cylindrical-crystal-3-8-32-768KHZ-32-768K/1556295898.html
18:32 rue_house houseton, I see a price discontinuty
18:32 Tom_itx the mill didn't like my fancy bit file
18:32 Tom_itx started doing funky things
18:32 rue_house hmm
18:32 Tom_itx but i was told it should work
18:32 katsmeow should i avert my eyes or not?
18:33 Tom_itx see there are functions like 'encoder' that use 3 pins... i used A only but not B & I
18:33 Tom_itx i reused the pins on B & I for another function
18:33 Tom_itx the synthesis assigned ground to the unused pins
18:33 Tom_itx (software pins)
18:34 Tom_itx i'm not sure this is the problem but something sure was funky
18:34 Tom_itx i'm rewiring it back like it was originally
18:36 katsmeow news is talking about 3am snow tornadoes Sunday
18:36 Tom_itx snow tornados!
18:36 Tom_itx never heard of that
18:37 katsmeow prolly because no one got pics of them at 3am
18:38 katsmeow it's like, how do you know? they knock the power out, make a lot of wind, and it's dark everywhere
18:39 katsmeow i cannot find any decent data on reverse engineerng penguin shoulders to move nuclear submarines
18:39 Tom_itx does it throw snowballs too?
18:39 tsmeow coughs up a hair
18:42 katsmeow this tells me nothing new : http://www.spxdaily.com/images-lg/actuated-spherical-joint-mimic-penguin-shoulder-lg.jpg
18:43 katsmeow every page about it is just a copy of the otehr pages
18:43 katsmeow i think it's misinformation, like subs made of corregated pipe
18:44 katsmeow do you see how that mechanism is supposed to work?
19:20 rue_house its just a tripod with funky hinge design
19:21 rue_house iirc
19:23 tsmeow ag
19:24 katsmeow and if you study it, half the points it looks like it might swivel on, can't because of the 90 degree bends put the other end in opposition
19:24 rue_house just got my order of 200 1x40 yellow pin headers!
19:24 rue_house yay mail, (boo canada post)
19:25 rue_house I suppose we need an alternative to canada post now
19:25 katsmeow horses?
19:25 rue_house maybe UPS, FEDEX, PURILLATOR and the bunch will start doing lettermail
19:25 katsmeow you can send letters via UPS now
19:25 katsmeow and FedEx
19:26 rue_house ah
19:26 rue_house canada post is firing half their staff and doubling their rates
19:26 katsmeow the gotcha is: UPS and USPS often hand off stuff to each other
19:26 rue_house a stamp will now be $1
19:26 katsmeow ouch
19:27 katsmeow use email?
19:27 rue_house yup
19:27 rue_house self obselescence
19:27 rue_house oh heh,
19:28 rue_house during the interrupt I was calling a fuction that incremented the milliseconds counter....
19:28 rue_house bit of overhead there
19:29 tsmeow fixed the dvd remote, to better watch star trek dark
19:29 rue_house ah
19:29 rue_house you like dr who?
19:29 katsmeow not that i need a remote, because the player is within arm reach anyhow, but all teh buttons are on the remote, almost none on the dvd player
19:30 katsmeow i watched some Dr Who when i could get pbs on tv
19:30 katsmeow i found most the britcoms funny as heck to
19:31 katsmeow even Fawlty Towers was funny when they weren't overacting
19:31 rue_house heh
19:31 rue_house what was the other one, captin something?
19:32 katsmeow the cat the robot, etc?
19:32 rue_house no, thats red dwarf
19:32 katsmeow yeas, i dunno
19:32 rue_house it was a comedy like fawlty towers, on right before or after, military setting
19:34 katsmeow the guy on Castle no was on a scifi series, i had to get that on dvd to see
19:36 katsmeow there was series with the ship being an Ai, i forget the name of it, i'd like a copy of that series too
19:36 rue_house red dwarf...
19:36 katsmeow no
19:36 rue_house hitchhikers guide also had ai
19:37 katsmeow Andromeda
19:37 rue_house ? that was about a virus outbreak
19:37 katsmeow no that was on the nasa ship at sea
19:37 katsmeow wait,, umm
19:37 rue_house :)
19:38 tsmeow looks conf
19:39 rue_house ok I think this code is about right
19:39 e_house tries to compil
19:39 katsmeow Lexa Doig is a Canadian actress best known for her role as Rommie in the science fiction TV series Andromeda.
19:39 katsmeow that Andromeda
19:39 rue_house *blink*
19:40 rue_house dunno
19:40 katsmeow with Kevin Sorbo
19:41 rue_house ... who?
19:41 katsmeow big tall guy, overacts a lot, played Hercules too
19:41 katsmeow http://actorsorbo.narod.ru/sorbo_eng/Andromeda_eng/Androm_backgr_eng/Androm_crew_eng.htm
19:43 katsmeow http://scifi.wikia.com/wiki/Andromeda_%28TV_series%29
19:43 katsmeow The Andromeda Strain is about the virus
19:44 katsmeow http://en.wikipedia.org/wiki/Andromeda_%28TV_series%29
19:44 katsmeow The series premiered on October 2, 2000 and ended on May 13, 2005.
19:44 katsmeow Andromeda was filmed in Vancouver, British Columbia, Canada
19:44 katsmeow that's where all the good scifi is made
19:49 any05568291 ...
19:49 rue_house internet cycling?
19:49 any05568291 i guess, i dunno, it's a lot for one nite
19:54 rue_house and wtf, so, a variable maxes out to 20, and the person is using a signed 16 bit variable for it? on an 8 bit controller!
19:54 any05568291 idiot compiler?
19:54 rue_house its not THAT smart
19:56 y05568291 eats more vitam
19:59 rue_house I already had much today, I'll substitute with cake
19:59 rue_house ok, the knock sequence detector compiles
20:00 rue_house 150ms for the knock to fade, sounds long...
20:00 any05568291 perform the knocking, log it on a storage scope, and measure it?
20:00 rue_house 6hz
20:01 rue_house I'd have to build a storage scope first
20:01 rue_house I ahve one started
20:01 y05568291
20:01 rue_house knocking at 6hz seems a bit of a challange
20:02 any05568291 prolly damage blood vessels
20:02 rue_house 1.2s seems like a long time to wait for the seqence to finish
20:02 any05568291 that's called "drama"
20:03 rue_house because its not realtime compare, its also the interval limit
20:03 rue_house hmm
20:04 rue_house is one knock is more than 25% out of time,
20:05 rue_house or the whole sequence is out by more than 15% it rejects
20:05 y05568291 sets up rue's knock detector to play various Hitchcock foreboding organ th
20:05 rue_house er avarage error exceeds 15%
20:09 rue_house http://hackaday.com/2013/12/19/a-weird-kind-of-printer/
20:09 any05568291 tune a few notch filters to the resonant freq of the door vibrations after it's hit?
20:09 rue_house never thought of ditching the screen and doing that
20:10 rue_house kat, I'm not using a door, or a knock
20:10 rue_house I'm using it to switch lights on and off with any sharp sound
20:11 any05568291 oh
20:12 any05568291 "clap on, clap off" ?
20:12 rue_house you have to understand, it only responds to a verry particular seqence
20:12 y05568291 wants to put her feets up in front of a heater for a w
20:13 any05568291 ok, clap_clap_____clap_clap_clapclap_____clap on"
20:13 any05568291 use morese code
20:13 rue_house 'shave and a haircut - two bits' being toggle livingroom light
20:13 rue_house maybe
20:14 rue_house so i can 'address' devices with the sound sequence
20:15 rue_house I think I can morph this code into fixed vocab voice rec
20:15 rue_house on an avr! :)
20:25 rue_house well, 200 yellow 40 pin headers, sweeeeeet
20:26 rue_house and I FINALLY got my 10 5x7cm protoboards, dont know how many sets of these I ordered and never came!
20:56 Tom_itx http://tom-itx.dyndns.org:81/~webpage/cnc/pendant/profile.jpg
21:10 rue_shop2 that was interesting
21:10 rue_shop2 ok, knock code
21:10 rue_shop2 pizo, meet scope
21:12 rue_shop2 oo I wonder what my radioactive calibration source is doing in the piezo element drawr
21:18 rue_shop2 50mv settles out after 10ms
21:18 Tom_itx what you workin on?
21:18 rue_shop2 so the ADC reading should be 10
21:18 rue_shop2 knock sequence detector
21:28 rue_shop2 it wsn't far off
21:38 rue_house almost 0 noise from the pizo
21:38 rue_house ^e
23:24 any05568291 .
23:24 rue_shop2 your still alive
23:25 any05568291 <blink>
23:25 any05568291 you're <<== the contraction of "you are"
23:26 rue_shop2 your <- 4 character optimization of you're
23:26 any05568291 some stuff on my ebay watch list has circled around and been relisted 100x and i still have not bought it
23:26 rue_shop2 has the price changed any?
23:26 rue_shop2 hmmm, code wont accept my knock
23:27 any05568291 test equipment prices have gone up the last 6 mo
23:27 Tom_itx you're = you are, your designates ownership
23:30 any05568291 7pcs seagate 300g scsi 10k drives, $19 , no bids
23:30 rue_shop2 +54 chipping
23:31 any05568291 i didn't check, i has no scuzzy
23:34 rue_shop2 its failing on code 1
23:34 rue_shop2 wrong knock count
23:35 rue_shop2 oooh, duh
23:37 rue_shop2 power blinks
23:37 Lola8088 here too
23:37 rue_shop2 snow falling off trees
23:38 any05568291 quick, put the piezo outside and detect it!
23:38 rue_shop2 says my knock timing sucks
23:40 any05568291 yeas, my paws are stained with dirty diesle and grease so the fingerprint detector says i am not me, and i have a sore throat, hurts to turn my head, so voice print said i am not me, grrrrr
23:42 y05568291 ponders rue signalling to the puters by tapping on the table, desk, and arm r
23:42 rue_shop2 yea, my knuckle is getting sour
23:42 any05568291 sour???
23:42 rue_shop2 sore
23:43 rue_shop2 it says my specific timing is too erratic
23:43 any05568291 you are pouinding your knuckle sore when you have a robot arm sitting over there doing NOTHING!?!
23:44 any05568291 use the lil one that refuses to sort parts
23:45 any05568291 set a biararsed NEMA contactor on the table, and switchit on/off with a t13
23:47 any05568291 set a variable speed drill in the bech vise, chuck a shrt arm in the drill, tie a short rope with a big knot in the end, so as the drill turns the knot whacks the tabletop
23:48 rue_shop2 kat, can you expalin the project I'm working on as it is to your understanding?
23:48 any05568291 you wana piezo mic to detect a sequence of noises
23:49 rue_shop2 detecting the noise was easy
23:49 rue_shop2 1M across the pizo, 150R in series to the avrs ADC
23:49 any05568291 i described 4 ways to make impact sharp noises that do not involve you pounding some portion of your body on the table till it bleeds
23:49 rue_shop2 a setting of 10 catches a knock quite nicely
23:49 Tom_itx what's the 1m across the piezo for?
23:50 any05568291 Tom static
23:50 rue_shop2 but you dont seem to understand I need to have a knock that does 'shave and a hair cut - two bits'
23:50 rue_shop2 its to kill the residual voltage from the circuit capacitance
23:50 any05568291 ok, program teh avr to pull in the relay to signal 'shave and a hair cut - two bits'
23:51 rue_shop2 and the 150R is to not stress the clamping diodes in the avr
23:51 rue_shop2 kat, or ANY up to 20 knock sequence
23:51 any05568291 ok, program teh avr to pull in the relay to signal ANY up to 20 knock sequence
23:51 rue_shop2 any specific 20 knock sequence
23:51 rue_shop2 yes
23:52 any05568291 surely you have relays laying around to make the required amount of sound or vibration when they slam in
23:52 rue_shop2 shave and a haircut just happens to be one everyone knows
23:53 rue_shop2 . ... . ..
23:53 y05568291 has a small pile of http://www.google.com/url?sa=i&rct=j&q=&esrc=s&source=images&cd=&cad=rja&docid=giLV1VvGAjQPBM&tbnid=yPIjVC3ABD3DWM:&ved=0CAUQjRw&url=http%3A%2F%2Fab.rockwellautomation.com%2FRelays-and-Timers%2F700-N-NEMA-Industrial-Relays&ei=Aim1Uum5EoT1kQeqmIG4Dg&bvm=bv.58187178,d.eW0&psig=AFQjCNH0kjdbSmcNHob0TzuPfgNOp6Yt1g&ust=1387690610164101

23:54 rue_shop2 how would a machine help me make it work well with a non-machine?
23:55 any05568291 the machine can make the timing accurate so you can tune that part,, because you can program irregularities into the relay clatter
23:56 any05568291 you can have the avr remember what the piezo heard you pound, and send that to the relay to duplicate it
23:56 rue_shop2 I think that suggetion just fixed my lack of screen problem
23:57 any05568291 ?
23:59 rue_shop2 advanced LED debugging
