12:01 AM katsmeow: https://hackaday.com/2017/12/11/what-you-need-to-know-about-the-intel-management-engine/
12:04 AM zhanx: late to the party on that one
12:04 AM rue_mohr: katsmeow, hi
12:04 AM rue_mohr: it looks like, with this arduino stuff, I have to make my own TCP packets, yay!
12:04 AM * rue_mohr grumbles
12:04 AM rue_mohr: so, wait
12:04 AM zhanx: yep you do
12:04 AM rue_mohr: I can sent a packet to an address that has someone elses return ip address?
12:04 AM katsmeow: zhanx, i was suspicious, and my P4 and winxp cannot do that tls spying
12:04 AM rue_mohr: how messed up is that
12:04 AM zhanx: reminder i wrote the arduino code to get gmail
12:04 AM katsmeow: reminder anything you wrote rue and i does not have
12:05 AM zhanx: its online and free and been copied a thousand times
12:05 AM rue_mohr: I want to listen to a tcp 'telnet' port
12:05 AM rue_mohr: and I cant find anything in this arduino library for 28J60 that can do it
12:06 AM rue_mohr: but, they do html chatter, so, it must be in here
12:06 AM zhanx: rue_mohr: that is hard to be honest
12:06 AM rue_mohr: I just want to listen to a port and parse the text that comes in...
12:07 AM rue_mohr: so kat, do you think you can get the ime to do stuff for ya?
12:08 AM katsmeow: it's after midnite, no
12:10 AM rue_mohr: I'm not superversed on ethernet, from what I can tell I need to open a local listening port, and push to a remote listening port
12:10 AM rue_mohr: if I want bidir comm
12:10 AM rue_mohr: but I just want to listen
12:10 AM rue_mohr: so I think I need to set up a connect somehow
12:11 AM rue_mohr: I dont know if that just means sending a packet with "I'm gonna listen on this port
12:11 AM rue_mohr: hmm
12:15 AM rue_mohr: I kinda feel like I'm wasting my time with this library
12:15 AM rue_mohr: so far nothing ads up
12:16 AM rue_mohr: ok, so...
12:16 AM rue_mohr: I send it a packet and get an ack
12:19 AM rue_mohr: my packet contains my ip and port for listening
12:19 AM rue_mohr: to which I get an ack
12:19 AM rue_mohr: and then messages when they come along
12:19 AM rue_mohr: the ip header has the packet type, the payload says the port
12:19 AM rue_mohr: now, I'm on a switch, so the only TCP packets I'll get are for me
12:19 AM rue_mohr: then I get to pick apart the IP payload and try to look for my data in the TCP payload
12:21 AM * rue_mohr pokes kat, any project progress?
12:21 AM rue_mohr: ugh
12:21 AM zhanx: 2nd one is improved 3rd one is a slightly different thing
12:21 AM rue_mohr: shouldn't have made that spelling correction
12:22 AM rue_mohr: the http server example
12:22 AM rue_mohr: its listening on a tcp port, and then sending a tcp reply
12:22 AM rue_mohr: and I cant find the code thats doing it
12:23 AM rue_mohr: every arduino library uses a different approach to operating the hardware
12:26 AM zhanx: yep
12:29 AM rue_mohr: I think I need the banter diagram for what I want to do
12:31 AM rue_mohr: zhanx, the idea is to listen to the automation port, if I get a message for a door chime, I send a serial command to an mp3 player to play a file number
12:32 AM rue_mohr: -> audio amp -> PA horn
12:32 AM zhanx: rue_mohr: that is more of a mesh thing
12:32 AM rue_mohr: I already have the server
12:32 AM rue_mohr: runs the house
12:32 AM zhanx: ok
12:32 AM zhanx: still not wrong
12:32 AM rue_mohr: you connect to port 77 and you get text messages
12:32 AM rue_mohr: if you send text, it goes to everyone else connected
12:32 AM zhanx: i get alarms for temps on my pc
12:33 AM zhanx: emails
12:33 AM zhanx: calls
12:33 AM zhanx: all port 80
12:33 AM rue_mohr: you stay connected with mine
12:33 AM zhanx: same with mine
12:34 AM zhanx: minus the solar ones
12:34 AM rue_mohr: point being, I dont know the nitty gritty of the network packets to talk to it
12:35 AM zhanx: added a reminder to my phone to review my code and help you tomorrow
12:35 AM rue_mohr: :)
12:35 AM rue_mohr: one of the things I want to fix up, is that often people come in the driveway, knock on the door, decide I'm not home and leave
12:36 AM zhanx: remember i have the 6 layer mesh and the message still makes it home, issue was the hone station was lost on it
12:36 AM rue_mohr: while I'm playing in the back yard
12:36 AM rue_mohr: so I got a beam sensor for the driveway
12:36 AM rue_mohr: and have wire from it up to the shop
12:36 AM zhanx: yes you need a mesh with a central control. mine is a Beagle bone black
12:37 AM rue_mohr: so, I suppose there are two parts, one thing to push the event to the network and one to ring the horn
12:37 AM zhanx: server holds the event
12:37 AM rue_mohr: mine is 'dingdong' the house doorbell and automation server
12:37 AM rue_mohr: I have this PC send events to it like 'furnace on'
12:38 AM rue_mohr: I have a large 'at' queue on the machine
12:38 AM rue_mohr: I'd like to add the tea machine to it to
12:38 AM zhanx: rue remember last year my code was stolen for the weather station and alerts?
12:38 AM rue_mohr: I thin that'd need to be wifi
12:38 AM rue_mohr: dont recall
12:39 AM zhanx: wrote all that code put on it git hub, guy from england stole it as his own
12:40 AM rue_mohr: with the arduino stuff, I keep expecting 'easy button' but I keep finding layers of code that are badly structured and cant really do much more than the examples that came with them
12:40 AM rue_mohr: wow
12:40 AM zhanx: it was funny ##electronics caught it for me
12:41 AM rue_mohr: huh
12:41 AM zhanx: its decent and works
12:41 AM rue_mohr: yea, not many people write origional code
12:41 AM zhanx: full mesh with error correction
12:42 AM rue_mohr: I know someone who works at a commerial software shop and they say that keeping their coders from just copying internet code is really hard
12:42 AM zhanx: took me 4 months and i asked a bunch of questions on it
12:42 AM rue_mohr: I dont want to write a enc28J60 library fromt eh ground up
12:42 AM rue_mohr: or a w5500 library
12:42 AM zhanx: not saying i didn't copying but i did make something that worked and no one else did
12:44 AM zhanx: rue its like that hack you did with the isa port
12:44 AM rue_mohr: :)
12:45 AM rue_mohr: yea, its amazing how many sites piggyback stuff, saying its theirs to try to promote their stuff
12:45 AM zhanx: wait till my idea on the filament is made
12:46 AM rue_mohr: srry. I'm sceptical of everything that isnt' off the ground yet
12:46 AM zhanx: you are fine on that
12:47 AM zhanx: but have you seen me this focus on something since 08?
12:47 AM rue_mohr: havn't we been working on that printer since 08? :)
12:48 AM rue_mohr: iirc the hexapod was the last time
12:48 AM zhanx: octpod
12:48 AM rue_mohr: but I know you focus on lots of stuff we just dont hear about
12:48 AM rue_mohr: its visible in the background hints
12:48 AM zhanx: like you also
12:48 AM rue_mohr: yea
12:48 AM rue_mohr: tooo busy to be bloggin
12:49 AM zhanx: lots fail and i am ok with that
12:49 AM zhanx: i learned
12:49 AM zhanx: can't say i am new at this anymore
12:50 AM rue_mohr: it struck me that I could use a more-or-less custom ethernet network for the mecha actualtor board communications
12:50 AM rue_mohr: but I think its pointless overhead
12:50 AM zhanx: well depends
12:50 AM zhanx: connections yes
12:51 AM zhanx: and then you could use the connections for a custom talk
12:51 AM rue_mohr: 6 channels @ 24Kbaud
12:51 AM rue_mohr: the current idea is TOSlink
12:51 AM rue_mohr: the actuators are broken out into 6 boards, each of which control 8 pid loops
12:51 AM * zhanx looks at the 6 cables he made tonight for a 3d printer
12:52 AM zhanx: i want feed back on the 3d printer
12:52 AM zhanx: 8 wires
12:52 AM zhanx: pita
12:53 AM rue_mohr: try to save the improvements for the second printer
12:53 AM rue_mohr: its hard
12:53 AM rue_mohr: there are so many things about the design that are horrid
12:53 AM zhanx: this is for the 3rd
12:53 AM rue_mohr: try to swallow them for the first one
12:53 AM zhanx: k
12:53 AM rue_mohr: I almost swallowed them all for my first printer
12:53 AM zhanx: oh i got an 8 mm drill bit per you
12:53 AM rue_mohr: :)
12:54 AM rue_mohr: geez, 5/16 is fine
12:54 AM rue_mohr: the extra .175mm wont kill anything
12:54 AM zhanx: sadly my 5/16 is worn out
12:54 AM rue_mohr: just dont do what we did to day in robotics and accedently drill it all out 3/8
12:54 AM zhanx: ok then
12:55 AM zhanx: oh i built a table today for the printer
12:55 AM rue_mohr: ok
12:55 AM rue_mohr: 3 or 4 point leveling :)
12:56 AM * rue_mohr pulls hair out and shouts "NO NONONONONO I WILL __NOT__ DO 4 POINT 'LEVELING' OF THE GOD DAMNED TABLE!!!!!"
12:56 AM zhanx: 4 point
12:56 AM zhanx: yes i am evil to myself
12:57 AM rue_mohr: np, first pass, stick with the program.
12:57 AM zhanx: glass came from a scanner
12:57 AM rue_mohr: when it works, go on a mod spree
12:57 AM rue_mohr: was it tempred?
12:57 AM zhanx: yep
12:57 AM rue_mohr: 8-S
12:57 AM rue_mohr: how you pull that off?
12:57 AM zhanx: work today
12:58 AM zhanx: its a scanner for check outs glass
12:59 AM rue_mohr: but you had to cut it, right?
12:59 AM zhanx: nope
12:59 AM rue_mohr: oh, there ya go them
12:59 AM zhanx: i paid 4 bucks to have it cut
12:59 AM rue_mohr: the only way I know to cut tempered glass is with a sand blaster
01:00 AM rue_mohr: huh
01:00 AM zhanx: he flipped it like 10 times on the jig
01:00 AM rue_mohr: UIPEthernet-2.0.6.zip
01:01 AM zhanx: rue can i send these winds to you
01:01 AM zhanx: 40 mph right now
01:01 AM zhanx: bursts at 64 mph
01:01 AM rue_mohr: no, not compatible
01:01 AM rue_mohr: were supposed to have 70km/hr winds this weekend
01:02 AM rue_mohr: I was supposed to check the genny :/
01:02 AM zhanx: gulf stream is changing for the spring
01:03 AM rue_mohr: war always bites you in the end
01:03 AM zhanx: is weather war now?
01:03 AM rue_mohr: go adafruit!
01:04 AM rue_mohr: no, gulf
01:04 AM zhanx: adafruit is happy
01:04 AM zhanx: met her
01:07 AM rue_mohr: netcat, send characters to port 1000 of 192.168.8.107
01:08 AM zhanx: rue when work slows down we need to write a real language software for kids
01:09 AM rue_mohr: I have a problem
01:09 AM rue_mohr: I'm dieing
01:09 AM rue_mohr: I might only have another 30 or 40 years left
01:09 AM rue_mohr: but I have to get with changing from an organic platform
01:09 AM rue_mohr: I'm severly behind
01:10 AM rue_mohr: so, my priorities have been tightened up a bit
01:11 AM rue_mohr: "My appologies, but I don't have the opportunity to save the world today"
01:12 AM rue_mohr: ... you ok?
01:13 AM zhanx: your diying?
01:13 AM rue_mohr: :) in a major way
01:13 AM zhanx: cancer?
01:13 AM rue_mohr: been studying the brain
01:14 AM rue_mohr: need to work out how to do the most complex software port EVER
01:14 AM rue_mohr: no cancer at this point, not known of anyhow
09:53 PM * katsmeow blinks
09:59 PM katsmeow is now known as katsmeow-afk
10:34 PM katsmeow-afk is now known as ^kat^
10:34 PM ^kat^: hmm
10:36 PM rue_mohr: hi
10:36 PM rue_mohr: so
10:36 PM ^kat^: oh
10:37 PM Tom_L: mm
10:37 PM rue_mohr: kat I missed you by one spelling correction last night
10:37 PM rue_mohr: I will never stop to correct my spelling again
10:38 PM ^kat^: i didn;t see the misspelling
10:38 PM rue_mohr: I was correcting it
10:38 PM Tom_L: stretch working now
10:38 PM rue_mohr: and just before I pressed enter you dissapeared
10:38 PM * ^kat^ waves at Tom
10:38 PM rue_mohr: kat, doyou have a box or avr programmer(s)?
10:39 PM ^kat^: not in front of me, a dragon 2, i think
10:39 PM rue_mohr: did you have any others?
10:39 PM ^kat^: nope
10:40 PM * rue_mohr stares at the floor and wiggles his foot,
10:40 PM rue_mohr: can we make a parallel port programmer?
10:41 PM ^kat^: no, don;t have dip 74HC126 or dip 74HC244
10:42 PM rue_mohr: a 1/8" HSS drill makes any dip into a soic adapter...
10:42 PM * ^kat^ has dip sockets
10:42 PM rue_mohr: with a little wire stitching
10:42 PM rue_mohr: oh, yea, well
10:42 PM rue_mohr: kat, ....
10:42 PM ^kat^: remember, i bought 2000 dip-18 sockets for $3.99 a few yrs ago?
10:42 PM * rue_mohr frowns and thinks for a bit
10:43 PM ^kat^: easy to resize them
10:43 PM rue_mohr: kat why do you have soic chips and dip sockets?
10:43 PM ^kat^: i have dipsockets for testing, and i thought i'd have a pcb driller
10:44 PM ^kat^: soic chips are cheaper
10:44 PM rue_mohr: and... I know your not lieing, but how does you not end up with a world class warehouse of dip chips?
10:44 PM ^kat^: did someone say i didn't?
10:44 PM rue_mohr: but no 244 or 125?
10:45 PM ^kat^: i have them in soic reels
10:45 PM rue_mohr: wow, we must have completely complimentrary stock
10:45 PM * ^kat^ grabs acamera
10:46 PM rue_mohr: almost everything I have is dip, with just a little soic
10:46 PM * rue_mohr gets camera
10:46 PM * rue_mohr glances at zhanx on the way out
10:48 PM zhanx: ?
10:50 PM ^kat^: took pics
10:50 PM ^kat^: importerating theminto the puter
10:52 PM * rue_mohr uploads camera!...
10:53 PM rue_mohr: arg, wrong command!
10:55 PM ^kat^: mogrifying

11:01 PM rue_mohr: arg I forgot to turn 2
11:02 PM rue_mohr: and 3
11:03 PM ^kat^: i didn;t pics of partslist, can do tho.....
11:04 PM rue_mohr: ooooo tektronic.
11:05 PM ^kat^: 6 scopes down here, the rest upstairs
11:05 PM ^kat^: the multichanelanalysers upstairs
11:05 PM zhanx: so basically more stuff then i will ever have
11:06 PM rue_mohr: and all the chipstock is soic...
11:06 PM zhanx: i can solder soic
11:06 PM ^kat^: cept for a couple armloads of diptubes on the stairs behind the elevator
11:06 PM rue_mohr: CANT... MAKE......OUT.... BOOK...... TITLES!!!!
11:07 PM rue_mohr: ^kat^, and your sutre thre is no 244 or 125?
11:07 PM rue_mohr: what do you have armloads of?
11:07 PM ^kat^: misc dips, as detailed in the parts list
11:08 PM ^kat^: which i am importing now
11:08 PM * rue_mohr tires to remember to breathe
11:08 PM * rue_mohr falls off edge of seat and scrambles back on
11:09 PM ^kat^: upstairs, tehre's like 3 R7603 , 3 7903, 2 7603, 1 5300(?), and 2 7904 scopes
11:09 PM rue_mohr: the bundle on the bookshelf looks like sram chips
11:10 PM ^kat^: it is, 16x256k 0ns smd
11:10 PM ^kat^: 20ns
11:10 PM rue_mohr: so, not 0ns
11:10 PM rue_mohr: hmm
11:11 PM rue_mohr: 16 bits would make a wickid state machine
11:11 PM rue_mohr: is the address and data multiplexed?
11:11 PM ^kat^: i must have 10,000 of 32kx8 10ns - 20ns
11:11 PM ^kat^: nope
11:11 PM rue_mohr: ooo wow
11:11 PM ^kat^: looooooottsa pins
11:12 PM ^kat^: you didn;t see the piles of sdram? i have seversl such piles, i had hopes
11:12 PM rue_mohr: so you could have 8 bits feedback, and have 8 bits input condition, and still have 8 independent bits output
11:12 PM ^kat^: got *new* sockets for them too
11:12 PM rue_mohr: yea, but I'm not excited about sdram
11:13 PM ^kat^: well, it's 100's of GB worth
11:13 PM rue_mohr: tooo many problems as a kid trying to work out how to use dram

11:13 PM ^kat^: sorry my book keepig isn;t upto snuff, but i do realise i need to do better
11:14 PM rue_mohr: whoa, every one of these pages is overfull of lists
11:14 PM ^kat^: wasn;t gonna stand up to take the pics either, not sorry about the pages being cropped becauseof
11:15 PM ^kat^: there's bags and boxes of capacitors and resistors, transformers, relays, upstairs, not gonna gotake their pics either
11:15 PM rue_mohr: ... do you have any differential output amps in there that you know of?
11:16 PM ^kat^: actually, there's a 25lb box of 30amp spst relays out in the barn too, and several boxes of ethernet transformers
11:16 PM ^kat^: iirc, a few of the cards have 600Mhz diff output opamps
11:16 PM ^kat^: lotta the ecl digital buffers do
11:17 PM ^kat^: for a while i just grabbed anything i didn;t already have that was under a penny per
11:17 PM rue_mohr: :) 610 '00 :)
11:18 PM ^kat^: yea,, there's some parts listed there
11:18 PM ^kat^: some things were so cheap i just bid on $4 them because shipping was gonna be free
11:18 PM rue_mohr: well yea
11:19 PM rue_mohr: its interesting to compare what details are important to us
11:19 PM ^kat^: there's some 10ns ram i listed the price for, because i REALLY wanted to use them in the C64 puters, modding them, but they are thru-hole, and no pcb driller
11:19 PM rue_mohr: but in nature our lists our similar
11:20 PM rue_mohr: whats the '521
11:20 PM rue_mohr: you didn't say
11:20 PM ^kat^: you got 13,049 74ABT373 in soic too?
11:20 PM rue_mohr: no
11:21 PM rue_mohr: http://ruemohr.org/~ircjunk/shop/semiparts5.jpg
11:21 PM rue_mohr: both our lists are on paper
11:21 PM rue_mohr: both hand written
11:21 PM rue_mohr: both overloaded pages
11:21 PM ^kat^: the odd octal latches are usually resettable
11:21 PM rue_mohr: sometimes state what package
11:21 PM ^kat^: i do, sometimes
11:22 PM ^kat^: i have the pdf on everything i have, xcept some of those sdram modules
11:22 PM rue_mohr: I started noting WHY I got the chip, like the LM386, I got for low speed fet driver
11:23 PM rue_mohr: the 7400 I use for logic in a 'half bridge driver'
11:23 PM ^kat^: the \chips\ is 5.4 GB , 11,611 files, mostly pdf
11:23 PM rue_mohr: the CD4060 I got for clocking smps supplies under crystal control
11:24 PM rue_mohr: the 74LS1G14 I got for oscillators
11:24 PM ^kat^: i wanted to build my deas for distributed cpus
11:24 PM ^kat^: i have maybe a foot stack of various FR4 too
11:24 PM ^kat^: i NEEDED that pcb driller
11:24 PM rue_mohr: so make it
11:25 PM rue_mohr: I know you can
11:25 PM rue_mohr: do you have any m328 avrs?
11:25 PM ^kat^: i can, but the pink ones i made were dirt cheap, they weren;t $5 each
11:26 PM ^kat^: i dunno, avr is up on a shelf, but i doubt it
11:26 PM rue_mohr: oo 4316, I knew there was an improved version out there
11:27 PM ^kat^: several really low-R fet switches for analog
11:27 PM ^kat^: some for digital too
11:28 PM rue_mohr: I sure was thrilled when I learned out the 688 for 8 bit address decoding
11:28 PM ^kat^: i may hve a few pounds of tiny44's, looks like 8 89c52 , thos 200 pcs of at90s4414
11:28 PM rue_mohr: hmmm
11:28 PM ^kat^: a few at90s2313
11:29 PM ^kat^: prolly more hiding somewhere
11:29 PM rue_mohr: so, if I mail you a dip 244, you wont get it will ya?
11:29 PM ^kat^: duno, guy said no more parcels will be delivered
11:30 PM rue_mohr: so, what do you have for etching baords?
11:30 PM ^kat^: i am guessing he will just take them home
11:30 PM rue_mohr: 3000 32kx8 sram!!!! $%^#$@%^
11:30 PM ^kat^: tank, bubbler, gallons of muratic, gallons of peroxide
11:31 PM ^kat^: laster printer
11:31 PM ^kat^: laser
11:31 PM ^kat^: there's more than 3000 , different part number and speed
11:31 PM rue_mohr: if I send it to the sherrif with instructions to deliver it to you, they have to, right?
11:31 PM ^kat^: told ya, i wanted to DO things
11:31 PM ^kat^: no
11:32 PM rue_mohr: is there a local courier up there?
11:33 PM ^kat^: i think there are several, thing is two of them also hold the packages for a week before delivery
11:33 PM ^kat^: i dunno how to get packages to them either
11:33 PM ^kat^: if you send it usps, it';s gonna be trashed anyhow
11:34 PM rue_mohr: started as a resistor list,
11:34 PM rue_mohr: the capacitors went in perpendicular
11:34 PM rue_mohr: that would be a complex number thing
11:34 PM rue_mohr: and then the chips came in at 45 degrees, that would be due to a mixed phase angle...
11:35 PM rue_mohr: :)
11:35 PM ^kat^: i was gonna list active parts vertically, and passives horizontally, to save paper
11:35 PM rue_mohr: right
11:35 PM ^kat^: off the top of my lil head, there's 5000 pcs of a 8kx8 sram
11:35 PM rue_mohr: hows my supper burning...
11:36 PM ^kat^: drat, i forgot about dinenr again
11:36 PM rue_mohr: ohohohohoh
11:36 PM rue_mohr: I didn't see it on your list
11:36 PM rue_mohr: do you have any 1 bit sram!?!?!!?
11:36 PM ^kat^: see,i need thigs to be networked, so the nukebox can seek me out whereever i am and tell me it;s done
11:36 PM rue_mohr: I always wanted to makea 1 bit dac audio delay
11:36 PM ^kat^: ueas, look up 74f74
11:37 PM rue_mohr: no like 1kx1
11:37 PM rue_mohr: but in sram
11:37 PM rue_mohr: I think their really rare
11:37 PM ^kat^: i have serial tone and amplifier chips in those tv cable boxes
11:37 PM rue_mohr: its almost always dram
11:37 PM rue_mohr: * 1 bit, with a seperate input and output bit
11:37 PM rue_mohr: do you know the ones I mean?
11:38 PM ^kat^: 7474 or 4013 is separate i/o and 1 bit per side
11:38 PM ^kat^: o, don;t remember them
11:38 PM rue_mohr: oh
11:38 PM ^kat^: i did work with 512byte and 2k byte srams, which aren;t made anymore
11:39 PM rue_mohr: they were 1 bit sram chips, with seperate input and output pins for the bit, small, like 1k, I dont think they muxed the row and column, but maybe
11:39 PM ^kat^: might have been 256 byte
11:39 PM ^kat^: and, 64 byte rams
11:39 PM rue_mohr: there was a small ram chip in the 7400 series, like 4x8 or soemthing...
11:39 PM ^kat^: oh, 1kx1? yeas, got a few 16kx1 and 64kx1
11:39 PM ^kat^: 4x4
11:40 PM rue_mohr: are they sram or dram?
11:40 PM ^kat^: i remember it, but never used it
11:40 PM ^kat^: dram
11:40 PM ^kat^: slow, 500ns cycle time
11:40 PM rue_mohr: the 74xx one was just something to be excited about in a databook for me
11:40 PM rue_mohr: I have lots fo the x1 dram chips
11:41 PM rue_mohr: a few ceramic with metal lids, I popped off to make cameras
11:41 PM rue_mohr: now that I have the avrs, I should write code to do that
11:41 PM ^kat^: 7481= [!what][!electronics][!integrated circuit] 16-bit Random Access Memory
11:41 PM ^kat^: 7488= [!what][!electronics][!integrated circuit] 256-bit Read-only memory
11:41 PM ^kat^: 7489= [!what][!electronics][!integrated circuit] 64-bit Random Access Memory
11:41 PM rue_mohr: huh
11:42 PM rue_mohr: only one was listed in the ECG catalog I had
11:42 PM ^kat^: i can peel open what's left of Tiggr and read her data
11:42 PM rue_mohr: (the ECG was better than the NTE)
11:43 PM ^kat^: ecg was floor sweepings, often got "exact replacement" in metal cans with leads reversed or some shirt like that
11:43 PM ^kat^: the vendor, Newark, didn;t believe till they showed up and i handed them a real part and then the crap they were sending us
11:45 PM ^kat^: if the replacement for a to-92 is a metal can 3/8 diameter with the base and collector reversed, in some cases there was no way to make it fit the space, and some dopes did installthem ad blew out the rest of the circuits
11:45 PM ^kat^: i would go to parts dept and pull every part and toss all the ecg into the trash
11:46 PM ^kat^: i am wondering if i can trust the local post office when i mail anything now
11:48 PM rue_mohr: ok, but all I had was the databook, and it was better
11:48 PM ^kat^: purchasing hated me, they once made a single-digit typo on some 1N4148 , and we got boxes of some huge stud mount triac
11:49 PM rue_mohr: hehe
11:49 PM ^kat^: we had equipment down, the fur was flying
11:49 PM rue_mohr: http://ruemohr.org/~ircjunk/shop/semiparts2.jpg
11:49 PM rue_mohr: appologies for tipping over the image
11:50 PM rue_mohr: the top two are ttl, the orange one is linear, and the bottom is cmos
11:50 PM ^kat^: you showed me
11:50 PM ^kat^: ah
11:51 PM rue_mohr: the one to the right of the bottom is microcontroller/cpu stuff
11:51 PM rue_mohr: http://ruemohr.org/~ircjunk/shop/semiparts3.jpg
11:51 PM * ^kat^ goes to get food outa nukebox as you type
11:51 PM rue_mohr: 2nd is "driver chips" , next down is 'perphials' 8255 and friends,
11:52 PM rue_mohr: then sockets and then 'good sockets' (machine pin) which also has the soic adapters stuffed into it
11:54 PM rue_mohr: have you done tape-and-donut pcb design?
11:54 PM ^kat^: no, done dead-bug and wirewrap tho
11:55 PM ^kat^: and taped pcb layout, had someone else etch and drill it, and then i stuff it and use it
11:55 PM rue_mohr: yea, tape and donut
11:56 PM rue_mohr: the little o s for pins
11:56 PM ^kat^: nowadaze, you say "taped a pcb layout", and people look at you like you are crazy
11:56 PM rue_mohr: came in packs for dips
11:56 PM ^kat^: oh, ok, yeas, i misunderstood, i thought you mean the drill bit that left dunuts around a hole
11:57 PM rue_mohr: I have some odd ones, conductive, I think their peel-and-stick traces, came with rolls of copper tape
11:57 PM ^kat^: i have a few rolls of black tape left, and the exacto knives
11:57 PM rue_mohr: what I have isnt the stuff for photomasking
11:57 PM rue_mohr: :) tapes got to have dried up by now
11:58 PM rue_mohr: I want to get into photomasking
11:58 PM ^kat^: yea,, and lithography got pricey
11:58 PM rue_mohr: I got some UV nailpolish
11:58 PM rue_mohr: the printer isn't black enough for photomasking from what I can tell
11:59 PM ^kat^: most leave pinholes
11:59 PM rue_mohr: I use a plotter
11:59 PM ^kat^: they also neck down a trace where it meets anything at an angle
11:59 PM rue_mohr: w/ bad ass pen
11:59 PM * ^kat^ nods
