00:00 katsmeow-afk you can even convert it to degrees-F by one resistor and a 2.5v ref
00:00 katsmeow-afk [23:41] <katsmeow-afk> National data sheet of Nov 2000
00:00 rue_house aha, mine is philips
00:00 rue_house ooooh bedtime
00:01 katsmeow-afk i actually have the NS hardcopy databook from before then too
00:01 rue_house haha the sensor got stuck, it just unstuck
00:02 katsmeow-afk http://www.alldatasheet.com/datasheet-pdf/pdf/8866/NSC/LM35.html <<== lookie at the first page
00:02 katsmeow-afk FIGURE 2. Full-Range Centigrade Temperature Sensor V OUT=+1,500 mV at +150�C ; +250 mV at +25�C ; -550 mV at -55�C
00:03 katsmeow-afk with numbers like that, it's even scled right for you
00:03 katsmeow-afk scaled
00:05 katsmeow-afk send 12v out to it, add an opamp to it, and you can run the signal on cheap wire a couple miles downt eh road
00:06 rue_house I'll look more laters, thankyou, gnight
00:06 katsmeow-afk but with a *minute* of time resolution anyhow, and RC filter should be plenty for a signal stayng on your own property
00:06 katsmeow-afk ok, good nites
00:15 katsmeow-afk .......
00:16 tsmeow-afk keeps on looking concerned that the pump or fan coming on will cause ground bounce that now feeds right to your p
00:23 rue_bed the tank is otherwise electrically floating
00:24 tsmeow-afk pets the cat and then touches the tank, listening to rue start screaming int he puter
00:25 rue_bed I was wondering if the moving water was building up static on the tank
00:25 rue_bed arcing over to the sensor and killing it
00:25 katsmeow-afk if it is conductive, and it prolly is a lil
00:25 katsmeow-afk not arcing tho
00:25 rue_bed all the sensors are dual shielded pair
00:26 rue_bed I'm wondering if its the line capacitance
00:26 rue_bed on the house I use unshelded
00:26 rue_bed lots longer runs
00:27 rue_bed I think the line capacitance may be killing the lm75 open collectors
00:27 katsmeow-afk can you lower the data rate? the clockspeed?
00:27 rue_bed dont think so
00:27 rue_bed its on a pc parallel port
00:27 katsmeow-afk you sample each sensor one at a time, right?
00:28 rue_bed yup
00:29 katsmeow-afk ok, hang a pcb out the with a 4066, or some otehr analog switch, and switch each sensor to a buffer, let the buffer feed the long line to the house
00:29 katsmeow-afk digital or analog buffer, whicever works for your sensor
00:36 tsmeow-afk goes away to put her hind feet

15:51 katsmeow-afk TinyURL was created!The following URL: data:image/png;...........has a length of 1534 characters and resulted in the following TinyURL which has a length of 26 characters: http://tinyurl.com/koqwfvw
15:53 katsmeow-afk it's a 9px x 13px png
15:53 katsmeow-afk the unique url to get it is many times larger than the image itself....... nah, that's not tracking

18:08 tsmeow-afk brings out a new line of liquid drinkable medicines, branded "no pill", so those ads that say "no pill delivered faster relief", i'll
18:53 katsmeow-afk kool, i can cram 4 desktop hdds into a 12" Tektronix plugin,, not much room for a controller card tho
20:32 rue_house cat pissed on the floor, lost my mp3 player (the ones that drowns out the thinking that drives me crazy), no ebay items arrived (none this week yet)
20:32 rue_house AAAAAAAAAAAAARRRRRRRRRRRRRRRRRRRRRRRRGGGGGGGGGGGGGGG
20:37 katsmeow-afk my camera arrived from Puerto Rico today,, no, it does NOT take SD cards,a nd no it is NOT a 1/8 regular usa video plug
20:38 katsmeow-afk so no pics of the islands on it
20:39 katsmeow-afk the card it wants is XD, about 1/2 the size of SD, they prolly quit making them 10 yrs ago
21:02 katsmeow-afk lawn mower : http://www.nasa.gov/images/content/214580main_jsc2007e047482_small.jpg
21:03 katsmeow-afk 12 tires, independant steering and power
21:15 rue_house katsmeow-afk, TD MD SD are all the same, just different shape
21:15 katsmeow-afk yeas, which means i cannot use the SD i have in the camera made for XD
21:15 rue_house er, I think XD is the same family
21:16 rue_house erp, damnit
21:16 rue_house oh its this one..
21:16 rue_house oh dear
21:17 rue_house there are 3 sizes of sd card tho, its stupid
21:18 rue_house damnit I cant beleive I lost the mp3 player
21:21 rue_house it was the last good mp3 player made on thsi planet
21:22 katsmeow-afk look it up ono ebay?
21:22 rue_house there are none
21:22 rue_house the new ones that superseeded it suck
21:23 katsmeow-afk no, i m,ean like i am doing with the cameras, old, obsolete, cheap, but still working
21:59 Tom_itx rue_house why did you let eds.dyn... lapse?
23:00 katsmeow-afk reddit is down too
23:01 katsmeow-afk no it isn't
23:04 katsmeow-afk http://i.imgur.com/DhZdgpU.gif
23:09 katsmeow-afk so Santa does not clean up after his reindeer??

23:51 rue_house http://eds.dyndns.org
23:52 rue_house they just delete the records randomly
23:52 katsmeow-afk Server not found
23:52 katsmeow-afk Firefox can't find the server at eds.dyndns.org.
23:52 rue_house I'll redo the records AGAIN
23:54 rue_house try now
23:55 katsmeow-afk Server not found
23:55 katsmeow-afk Firefox can't find the server at eds.dyndns.org.
23:56 rue_house it'll come up in a while
23:56 katsmeow-afk Resolving eds.dyndns.org... failed: Host not found.
23:56 katsmeow-afk wget: unable to resolve host address `eds.dyndns.org'
23:56 katsmeow-afk mind if we fret in the meantime?
23:57 katsmeow-afk so if i put 3 hdds in a 12" Tek 7k plugin formfactor, i have room for a controller card, and can operate the drives as a raid, or not
23:58 katsmeow-afk used only for error checking and redundancy, i can have the drives store copies,a nd simply vote on who has the valid data
23:59 katsmeow-afk ok?
