00:14 any86927516 as usual, there's gotchas
00:16 any86927516 each valve needs a 3" or 4" gear , and the driving motor needs a shaft with as much gear teeth as (the tallness of stack of valve gears is divided by 2)
00:16 any86927516 that is, unless i can make all the gears, the cost of gears kills the project
00:18 any86927516 unless i use only 3 valves, and direct drive, or chain drive them (sprocket on motor shaft, pulley on valve shaft, cause it's only 90 degree turn on the valve)

09:46 rue_mohr kat, yo uhave that grinder/divider setup, you can make clock gears
09:47 rue_mohr with the pins in the pinion gear
10:46 any86927516 what grinder/divider setup do i have?
11:05 any86927516 http://www.hp.com/hpinfo/abouthp/histnfacts/museum/earlyinstruments/0006/0006front.html <<== i recall looking at one of those and commenting on the upside-down hp logo, turns out, dynec was a subsidiary of hp, and used the upside down hp as dy-nec logo
11:06 any86927516 the counter resembles a "Coulter counter" i once had to keep running, iirc, max count clock was 100Khz
11:07 any86927516 the columns on the front panel had NE2 bulbs behind them, on a module with 4 12AX7, each 12AX7 was a flipflop, the 4 tubes made a 4 bit counter, wired with diodes to lite the 10 neon NE2 to display the count

11:22 any86927516 ?? 3GHz P4: 6GFLOPS peak
11:22 any86927516 ?? Nvidia GeForce FX5900 (2004): 53 GFLOPS
11:22 any86927516 ?? 128 FP units in parallel at 450MHz
11:22 any86927516 ?? Nvidia GeForce 7800 (2006) GTX512: 200GFLOPS
11:22 any86927516 ?? 192 FP units at 550 MHz)
11:22 any86927516 ?? ATI X1900 (2006): 554 GFLOPS
11:22 any86927516 ?? Around 400 FP units at 650MHz, and around 400W!
11:22 any86927516 well, so much for formatting
11:24 any86927516 but you see how the Gflop race is won: 400 floatng point descrete "chips" on the silicon slab, each doing two operations at a time, running as slow as a P1 cpu, and it's up to you and your compiler to keep all 400 "chips" busy
14:01 Tom_itx http://www2.electronicproducts.com/Google_s_Transparency_Report_reveals_big_spike_in_online_government_surveillance-article-fajb_google_transparency_nov2012-html.aspx
14:52 any86927516 "big spike" = they got more of those megawatt supercomputer centers online
14:53 any86927516 it's not even a spike, it's a permanent increase
14:56 any86927516 The first Report was published in 2009. They�re released twice a year and upon reviewing them in succession, it�s hard not to notice a continued and steady increase in government requests for data. <<== NOT a "spike"
14:58 any86927516 Believe it or not, over 10 million acres of coastal water is considered contaminated with undetonated explosives. While they tend to be on the smaller side of the bomb scale, the biggest concern with them is the fact that the sea water causes them to rust and corrode, making them even more dangerous.
15:03 any86927516 The switch incoproates a battery level indicator <cough>
15:04 any86927516 it's a $400 flashlite, you'd think they could afford a spell checker

15:08 any86927516 Their very cleaver design methodology allowed us to build the MAX44009 <<== AH HAH!!! so they ARE using cleavers!
15:10 any86927516 http://www2.electronicproducts.com/16_bit_FRAM_MCU_takes_only_100_%C2%B5A_MHz-article-ICDJH03_TI_MSP430FR5969_Dec2012-html.aspx
15:10 any86927516 The MSP430FR5969 microcontroller has 64 Kbytes of FRAM and requires only 360 nA in real-time clock mode and less than 100 �A/MHz in active power mode. The IC also features a fast wake up time of 6.5 �s. a three channel DMA, an 18-channel 12-bit A/D converter, 2 Kbytes of SRAM, and capacitive touch I/O.
15:10 any86927516 The 16-bit MCU runs at 16 MHz and has a RTC, a 32-bit multiplier, 128- or 256-bit AES encryption, random number seed, five 16-bit timers, and 16-bit CRC. The device operates at -40� to 85�C and is part of a family with nine versions in three package types.
15:10 any86927516 ($2.75 to $3.35 ea/1,000 - samples available now.)
15:12 any86927516 360nA = a C cell can power it asleep for 2.5 million hours , or until the universe burns out, whichever
15:12 any86927516 285 years, actually
15:21 any86927516 released last week : http://www.nxp.com/news/press-releases/2012/11/nxp-revolutionizes-simplicity-with-lpc800.html
15:22 any86927516 parametric search of the LPC800 family : http://www.nxp.com/parametrics/71785/
15:30 any86927516 In the following list, it helps to think of the typical 200 mA�Hr capacity of a CR2032 lithium coin cell as 200,000 ?A�Hr, or 22.8 ?A�year. Thus, considering only the CPU draw, such a battery could supply a 0.7 ?A current draw for 32 years. (In reality, battery self-discharge would reduce this number.)
18:34 any86927516 Pricing for the LPC810 starts at $0.39 USD.
18:51 any86927516 this one is a horrible problem trying to solve the question of why teen boys aren't racing around the restroom peeing in each other's game ports : http://www2.electronicproducts.com/Pee_controlled_gaming_coming_to_your_bathroom_soon-article-FANE_urine_games_Nov2012-html.aspx
19:09 any86927516 [18:50] <any86927516> is there a formula for capacity of 3-sided 3D triangle?
19:09 any86927516 [18:51] <any86927516> 30ft each side, 12ft tall
19:09 any86927516 [18:52] * any86927516 approximates with a cone
19:09 any86927516 [18:54] <any86927516> 2800 cuft , 21,000 gallons, take 2 weeks to make it resemble full of water @ 1500 gal per day
19:09 any86927516 [18:55] <any86927516> that would be 7 months @ 100 gal per day onto a garden,, of course after that the fish would dry out
19:09 any86927516 [18:56] <any86927516> i could add more water
19:23 zhanx nickserv hates me
19:44 zhanx ping
19:47 any86927516 it's zhanx!
19:47 y86927516 lifts a protein shake in greet
19:51 any86927516 http://www.mouser.com/pdfdocs/LPC81XMv1_1pdf.pdf <<= not bad for a 32bit 30Mhz 39 cent chip?
19:56 any86927516 all the anlog stuff is TBD tho
20:03 any86927516 crap, their 50Mhz ARM chip's adc is : � 10-bit conversion time . 2.44 .s (up to 400 kSamples/s).
21:00 any86927516 hmm, .064 FR4 pcb with a via will delay the signal 9.75ps just traveling thru the via
21:31 any86927516 good grief, the germanium transistor invented in 1947, the silicon transistor in 1954, the integrated circuit in 1958, the 1.544Mhz T1 line was invented in 1958 and first went into use in 1962, and then it took 40 years before i could get 1Mbit DSL
21:32 any86927516 In 1954 Epsco introduced an 11-bit, 50-kSPS vacuum-tube based ADC. This converter is believed to be the first commercial offering of such a device.
21:32 any86927516 The Epsco "Datrac" converter dissipated 500 watts, was designed for rack mounting (19"� 15" � 26") and sold for $8,000 to $9,000
21:35 any86927516 The Safeguard program became entangled in the politics of the SALT talks with the Soviet Union, and was eventually scaled back significantly. In the end, the Grand Forks, North Dakota site was the only site ever built; it became operational on October 1, 1975.
21:35 any86927516 the next day, On October 2, 1975, the House of Representatives voted to deactivate the Safeguard program.
22:20 any86927516 6am this Sunday is supposed to be 25F here
22:21 any86927516 i guess that's better than at 25am it being 6F
22:30 rue_mohr ok
22:32 any86927516 <cough>
22:32 rue_mohr did you see my new clips?
22:33 any86927516 no?
22:33 rue_mohr http://www.ebay.ca/itm/270723567658
22:34 rue_mohr wrong one
22:34 rue_mohr http://www.ebay.ca/itm/271000802802
22:34 any86927516 for real, that price is too high
22:34 rue_mohr the first one?
22:35 rue_mohr its made ok
22:35 any86927516 no pic
22:35 rue_mohr scroll down
22:35 any86927516 and it's $3
22:35 rue_mohr its part of a bunch of non-dollar things I bought
22:35 rue_mohr stuffs that I wanted to get for the shop
22:36 Tom_itx encoder works (kinda) but the menu is formatted for a 20 x 4 lcd
22:36 any86927516 http://www.ebay.com/itm/320643277283?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649
22:40 y86927516 tries to route all the vga cables so none are over 2ft
22:46 y86927516 s
22:47 any86927516 can do it, but then on the other paw i don't wanna spend time hooking up so many puters, when what i'd rather have is the fileserver box
23:20 any86927516 whyfor did xhanx leave without saying anything?
23:21 rue_mohr maybe there was nothing to say
23:21 any86927516 oh
23:25 rue_mohr !assist
