[00:04:17] <rue_house> 15 for the duration of the switch transition? about 1.5ns?
[00:05:23] <katsmeow> if the opamp oscilates, both tips could come on and stay on
[00:08:29] <rue_house> then they would turn into resistors
[00:09:24] <katsmeow> yeas?
[00:12:00] <rue_house> .. no thats all
[00:14:15] <katsmeow> you see the neat tricks tho? there's no resistors between the TIP-bases and the common-B-E transistors, because the opamp is supplying all the current, and limits to 20ma anyhow
[00:14:58] <rue_house> ok
[00:15:14] <katsmeow> by putting the voltage divider aon those common-B-E bases, they are high value, low current, they don't need to hold the transistors all that still stiffly
[00:15:46] <katsmeow> the base current can be 1/80th whatever the opamp pulls on the emitters
[00:16:39] <katsmeow> the 12k resistors let the opamp move a volt, which is inside the dead-band of the two emitters, because the bases are tied together
[00:17:53] <rue_house> is the tip100 a darlington?
[00:19:08] <katsmeow> bot tips are
[00:19:32] <rue_house> I like your darlington symbol, I think I'll use that...
[00:19:49] <katsmeow> i thought it was standard, it's all i ever used
[00:19:54] <rue_house> I cant mentally simulate that state
[00:19:56] <rue_house> stage
[00:20:14] <rue_house> I dont think its passed any of my cycles
[00:20:16] <rue_house> circles
[00:20:19] <rue_house> oh boy
[00:20:28] <rue_house> whats wrong the the sentence maker?
[00:20:30] <katsmeow> where are your mentals hanging up on it?
[00:20:58] <rue_house> it seems to have a feedback effect
[00:21:08] <rue_house> I think I can only go 3 itterations or so
[00:21:09] <katsmeow> who does?
[00:21:17] <rue_house> m
[00:21:18] <rue_house> e
[00:21:21] <katsmeow> oh
[00:21:52] <rue_house> its a common, .... base amp
[00:21:54] <katsmeow> well, try cutting the schematic in half , horizontally, see if that makes it clearer
[00:22:03] <rue_house> a totempole common base amp?
[00:22:09] <katsmeow> ok
[00:22:19] <rue_house> the 12k is feedback?
[00:22:25] <katsmeow> nope
[00:22:33] <rue_house> hmm
[00:22:49] <rue_house> I might not be in a mental state to parse it either
[00:23:09] <rue_house> it looks like audio amps I'v seen
[00:23:21] <katsmeow> without the 12k , the output of the opamp hasto travel betweem 7v-8v to turn those lile to-92 on
[00:23:56] <katsmeow> there's a lil more than a volt of dead there, centered on 7.5v
[00:24:04] <rue_house> above 7.5, the botom on turns on, below, the top one does
[00:24:14] <katsmeow> because the bases are tied together, to ensure they never can be on at the same time
[00:24:52] <katsmeow> (just another trick)
[00:25:49] <rue_house> zippo:/files/programming/c/resistor# ./VOUT
[00:25:49] <rue_house> +V
[00:25:49] <rue_house> R2
[00:25:49] <rue_house> VR1
[00:25:49] <rue_house> R1
[00:25:51] <rue_house> GND
[00:25:53] <rue_house> Divider supply: 7.5
[00:25:55] <rue_house> bottom resistor: 12000
[00:25:57] <rue_house> top resistor: 1000
[00:25:59] <rue_house> Vout is : 6.923077
[00:26:29] <rue_house> collector at 7V from centre, and the base is 7.5
[00:26:33] <rue_house> ...?
[00:26:41] <rue_house> IC = IE
[00:26:44] <katsmeow> what?
[00:26:56] <rue_house> ... I dont know
[00:28:25] <katsmeow> because of the gain of the TIPs, those to-92 shold not need to saturate
[00:29:48] <katsmeow> 10ma into the TIP bases at 500x gain is 5amps , the switcher will collapse to self-protect at 5amps, so if the gate needs 5amps to drive it, i will need to slow the transiton down
[00:30:23] <katsmeow> turning the mosfet *OFF* won't pull 5aps from the psu, but turing it on might
[00:30:47] <katsmeow> i do not wanna be switching it that hard
[00:31:05] <katsmeow> but fast turn-off in case of short would be a good thing
[00:32:20] <katsmeow> with neither TIP turned on, the gate is floating, so the opamp will be drifting up and down like a really slow pwm
[00:59:41] <katsmeow> didn't Hymie the robot get his own show?
[01:10:09] <rue_house> dunno
[02:24:57] <katsmeow> ....

[20:50:44] <rue_shop3> your book is here
[21:24:41] <Moon_> HAY'
[21:24:46] <Moon_> sorry im so lame
[21:24:54] <Moon_> woooh
[21:25:17] <Moon_> you should bring it over
[21:26:16] <rue_shop3> I'm burned out today
[21:26:23] <rue_shop3> I'm just workin on staying awake
[21:26:38] <Moon_> XD
[21:27:51] * katsmeow throws otc drugs at rue
[21:28:09] <Moon_> :P
[21:42:00] <katsmeow> hmm, no one in #garfiend
[21:43:56] <rue_shop3> I'm here I think

[21:45:53] <rue_shop3> hmm
[21:46:54] <rue_shop3> I think I have more of those drives...
[21:48:49] <Tom_itx> i think i finally got my program to work
[21:49:08] <Tom_itx> i think alot of the problems i was having was a corrupt index file
[21:49:25] <Tom_itx> not the code
[21:50:06] <rue_shop3> database?
[21:50:30] <Tom_itx> yes
[21:51:54] <Tom_itx> had to redo the ledger entry system
[21:53:15] <Tom_itx> took a 30 min quiz today in ~2min and spend the rest of the time doing extra problems not even in the book
[21:53:24] <Tom_itx> (i'd requested more from the prof)
[21:54:24] <katsmeow> 250 PCS ATMEL 25128AN.SI 18 Integrated Circuits ?
[22:00:39] <katsmeow> does xhanx have a email address yet?
[22:06:51] <rue_shop3> 128k ...
[22:07:00] <rue_shop3> flash or eeprom?
[22:07:34] <rue_shop3> serial eeprom
[22:08:30] <katsmeow> welp, they are $4 so far
[22:09:13] <katsmeow> that's 500 pins per dollar
[22:09:28] <rue_shop3> ok I drilled the holes for mounting the shaker motor
[22:09:37] <rue_shop3> that took... an hour and a half...
[22:09:51] <rue_shop3> 90 minutes, 8 holes
[22:10:11] <rue_shop3> lets just call it 10 mins per hole :)
[22:10:25] <katsmeow> took yur time, eh?
[22:10:41] <rue_shop3> I'm fighting nodding off
[22:11:02] <rue_shop3> I'd go start supper, but I dont want to eat
[22:11:06] <rue_shop3> ever...
[22:11:17] <rue_shop3> leads to messsy things...
[22:11:29] <katsmeow> HB56G136B-7 hitachi mobo ram, of some sort never seen before
[22:12:17] <katsmeow> 2meg x 36 dram, i spode
[22:12:23] <rue_shop3> 70ns dram
[22:12:47] <katsmeow> The HB56G236 is a 2M × 36 dynamic RAM module, mounted 4 pieces of 16-Mbit DRAM (HM5118160)
[22:12:48] <katsmeow> sealed in SOJ package and 4 pieces of 2-Mbit DRAM (HM512200) sealed in SOJ package.
[22:13:11] <katsmeow> can't make up your mind, use both rams!
[22:13:24] <rue_shop3> 2.73/2.42 W (max)
[22:13:43] <rue_shop3> Refresh period
[22:13:43] <rue_shop3> ¾ 1024 refresh cycles: 16 ms
[22:13:48] <katsmeow> 72-pin single in-line package .... 386?
[22:13:55] <rue_shop3> yea
[22:14:27] <katsmeow> so 80 of them for $4 is rather iffy
[22:15:21] <rue_shop3> its built in 2 16 bit, memories with 2bit ecc
[22:15:24] <katsmeow> 70ns is like superslow any more
[22:16:24] <katsmeow> operating current: 500ma
[22:16:36] <katsmeow> standy current: 16ma
[22:18:03] <rue_shop3> the CAS and RAS have to be netween 20 and 50ns apart
[22:19:21] <katsmeow> yeas, this is the dram you grew up to hate
[22:24:20] <katsmeow> random read or write cycle time : 120ns
[22:24:52] <katsmeow> may be 60 to access, but then you haveto wait around anotehr 60 before you can read or write again
[22:24:59] <katsmeow> speak of the devil
[22:25:00] <zhanx> Evening
[22:25:26] <zhanx> I am not the devil
[22:25:57] <katsmeow> a whirling dervish?
[22:26:15] <zhanx> Same thing
[22:26:17] <katsmeow> anyhoo, you got memoserved, and i don't has yur email
[22:28:46] <katsmeow> i guess the seller heard you have a new job ;-)
[22:29:29] <zhanx> Get paid tomorrow
[22:29:53] <katsmeow> those dram cards are only 1M-words, rue
[22:30:09] <zhanx> 569.80 :( for a week
[22:30:51] <katsmeow> all 80 modules wold be 320 Mbytes , with some leftover ecc bits
[22:31:20] <katsmeow> a stack 20 inches tall making only 320 Mbytes
[22:31:40] <zhanx> And harbor freight website could fit on that
[22:32:27] <katsmeow> you dl'd the whoe site?
[22:33:03] <zhanx> No I didn't have 512 byte to s
[22:33:12] <zhanx> Spae
[22:33:19] <zhanx> Uggh
[22:33:47] <katsmeow> zhanx just page faulted
[22:34:25] <zhanx> I faulted keyboard or brain
[22:34:35] <zhanx> Long day
[22:34:53] <zhanx> Involved torches, welders etc
[22:35:52] <katsmeow> i used grinder
[22:36:12] <katsmeow> lost about an inch of grit around the disc
[22:37:12] <zhanx> Crap that's my go to bed alarm
[22:37:19] <zhanx> Night
[22:37:28] <katsmeow> oh, gnites
[22:38:15] <zhanx> Night kat
[22:43:56] * katsmeow bids $4 on 500 pcs of 220u 35v smd caps
[23:01:40] <katsmeow> so what are my chances of making a pata-to-serial adapter using ecl chips, shoostng the data thru simple 2-pole switches, and then converting back to pata to the mobo doesn't know i did any converting?
[23:05:49] <rue_shop3> $3 on ebay
[23:07:20] <katsmeow> i was aiming for cheaper and 2-wire , sata is 4 wire, and i'd need 2 converters, each sde of the switch, making my cost for trying to save money be $120 for 20 drives
[23:19:30] <katsmeow> why can't i use a 16x16 crosspoint switch and feed the hdds right up into the stacked mobo above?
[23:27:02] <katsmeow> i'd need to write cache, maybe read cache, make a bufferthat looks like the hdd, to whatever mobo is plugging in, even if two mobo are on the same hdd
[23:44:18] <rue_shop3> write only memory?
[23:44:51] <katsmeow> well, read-thru to ht ehdd
[23:45:11] <rue_shop3> hmm
[23:45:19] <rue_shop3> readable write-only memory...
[23:45:29] <rue_shop3> RWOM
[23:47:18] <katsmeow> an interface per outside connection, the interface caches writes if it doesn't have that specified hdd connected already, on reads it connects to that hdd
[23:48:07] <katsmeow> by handshaking with the otehr interfaces, and keeping a shared FAT and SAT tables, and no interrupting, it should be ok
[23:48:21] <rue_house> its how the petabyte drives work
[23:48:26] <rue_house> readable write-only
[23:48:37] <rue_house> once its full, its full
[23:49:04] <katsmeow> i don't wanna do that
[23:49:33] <rue_house> the idea being that it'll take as long to use up a few hundred petabytes as it would to wear out a terabyte size drive
[23:49:54] <rue_house> REAAAALY good for data storage
[23:50:06] <rue_house> bad for lots of updates
[23:50:11] <rue_house> but acceptable
[23:50:34] <katsmeow> and if it goes bad, you lose the whole kit and it's caboodle
[23:50:41] <rue_house> it dosn't
[23:50:43] <katsmeow> oo, put that in your word list too
[23:50:54] <katsmeow> how does it not go bad?
[23:50:55] <rue_house> 3d holographic crystal etching
[23:51:04] <katsmeow> crystals crack
[23:51:08] <rue_house> thats why its not erasable
[23:51:21] <rue_house> yea well a crack wouldn't be good
[23:51:52] <katsmeow> and, atoms can migrate
[23:52:08] <rue_house> but because its holographic, bits are self-redundant
[23:52:11] <katsmeow> iirc, some migrating has caused some diamonds to discolor
[23:52:55] <katsmeow> this false advertising on memeory chips is severe lying
[23:53:20] <katsmeow> 6ns cycle time! ( but one read or write takes at least 20ns
[23:54:02] <katsmeow> even those 70ns drams are 120ns cycle time
[23:54:12] <rue_house> but thats what lead to the technology, the acception that it will have a finite life, WHEN its full, you transfer the bits you want to keep to another drive
[23:55:04] <katsmeow> so who sells it, and for how much?
[23:55:19] <katsmeow> what if the lasers bcome misaligned?
[23:59:14] <rue_house> "When asked 'why are you irradicating the human race?' the aliens answered 'because they are annoying', and with that, no human could disagree."
[23:59:28] <rue_house> katsmeow, sorry, they wont exist for a while

[23:59:54] <rue_house> remember the guy who made the system that burned data into a roll of scotch tape?
