[22:45:56] <zhanx> Evening
[22:46:15] <katsmeow> hie
[22:46:30] <zhanx> Hi
[22:46:56] <katsmeow> wassup ?
[22:47:18] <zhanx> Air muscles
[22:47:22] <zhanx> Max psi
[22:47:44] <katsmeow> have you tried using water instead, to get more stiffness?
[22:47:53] <zhanx> Not yet
[22:47:58] <rue_shop3> hey
[22:47:59] <rue_shop3> kat
[22:48:06] <rue_shop3> whats with missing ttl numbers
[22:48:14] <zhanx> I just got an air compressor
[22:48:16] <rue_shop3> 74ls18 19
[22:48:25] <rue_shop3> I found the 74ls01
[22:48:31] <katsmeow> simple, some oem claimed the numbers, made someting, went bust, and the numbers cannot be used
[22:48:32] <rue_shop3> they liked open collector outputs
[22:49:15] <katsmeow> easy way to make huge AND gates
[22:49:16] <zhanx> Oh and tomorrow more chain drive crapola
[22:50:17] <rue_shop3> and and/or
[22:50:25] * katsmeow finally found a 1/4 mandrel with a 1/4 shank , in NZ
[22:50:56] <zhanx> Router mandrel?
[22:51:02] <rue_shop3> 20, 21, 22?
[22:51:05] <katsmeow> disk cutter
[22:51:08] <rue_shop3> I thought one of those was a 1-shot
[22:51:23] <katsmeow> 122, 123, 221 are one-shots
[22:53:00] <katsmeow> http://www.ebay.com/itm/162143341494
[22:53:07] <rue_shop3> 29 is DNE
[22:53:18] <rue_shop3> I'm printing a databook
[22:53:19] <katsmeow> DNE ?
[22:53:24] <rue_shop3> does not exist
[22:55:01] <katsmeow> remember in the 1960's there was so much new being made, that Signetics started their own ttl like : the 82 series , there was also the 8T series, and the mil insisted on their own series : 54
[22:55:12] <rue_shop3> 34
[22:55:31] <rue_shop3> I think I have some 82, didnt' catalog it
[22:55:44] <rue_shop3> 34 dne
[22:56:27] <katsmeow> the CD40xx family didn't make everyone happy, Mot made the 140xx to mess things up
[22:57:03] <rue_shop3> most of the missing numbers exist in 1xx or 3xx
[22:57:03] <katsmeow> then someone came up with the bright idea of giving ttl numbers to the 40xx family: making chips like the 74C04
[22:57:17] <katsmeow> lots missing in 500 and 600 too
[22:57:28] <rue_shop3> yea but mots 140xx directly map to 40xx
[22:59:23] <katsmeow> https://en.wikipedia.org/wiki/List_of_7400_series_integrated_circuits
[22:59:48] <katsmeow> 7434 6 hex noninverters
[23:14:18] <rue_shop3> printer putz up, I give up for tonight
[23:14:55] <rue_shop3> I got from 7400 to 7451
[23:16:24] <katsmeow> 74121= [!what][!electronics][!integrated circuit] Monostable Multivibrator
[23:16:24] <katsmeow> 74122= [!what][!electronics][!integrated circuit] Retriggerable Monostable Multivibrator with Clear
[23:16:24] <katsmeow> 74123= [!what][!electronics][!integrated circuit] Dual Retriggerable Monostable Multivibrator with Clear
[23:16:24] <katsmeow> 74124= [!what][!electronics][!integrated circuit] Dual Voltage-Controlled Oscillator
[23:17:02] <katsmeow> are you co9llecting the 74xx ttl family?
[23:17:20] <katsmeow> 74221= [!what][!electronics][!integrated circuit] Dual Monostable Multivibrator with Schmitt trigger input
[23:18:05] <rue_shop3> I already have it all in little drawrs on the wall
[23:18:18] <rue_shop3> but I want to build a databook that includes all the other stuff
[23:18:33] <rue_shop3> like the avr microcontrollers and the mosfets and diodes etc etc
[23:18:44] <rue_shop3> boards like the arduino mini pro
[23:19:03] <katsmeow> Tiggr has listed 588 74** numbers
[23:19:11] <rue_shop3> that has the 2803 etc
[23:19:16] <rue_shop3> in a paper book
[23:19:20] <rue_shop3> that I can just open and look at
[23:19:27] <rue_shop3> thats the idea
[23:19:40] <katsmeow> up to 74163245= [!what][!electronics][!integrated circuit] Low Voltage 16-Bit Dual Supply Translating Transceiver with 3-STATE Outputs
[23:23:00] * katsmeow tries to open a 974MB text file
[23:27:27] <katsmeow> there was a brit tv series, in 2nd season atm, "Eve UK" , about a robot girl in a human family
[23:27:40] <katsmeow> i thing the target audience is tweens
[23:37:02] <rue_house> hmm
[23:37:17] <rue_house> I need to work out a good design for my 32 channel solinoid driver
[23:37:30] <rue_house> 60VDC, so I have a bunch of bipolars
[23:38:02] <rue_house> I suspect the kickbacks will keep the average load at really low
[23:38:30] <rue_house> but the timing needs to be in 16Mhz ... oh, no... its not... I think its 3.~Mhz steps
[23:38:39] <rue_house> damn, I need to find out what that crystal was
[23:50:00] <rue_house> "its soemthign a cat would say:" "Here, make yourself feel better by petting me."
