00:00 katsmeow-afk yeas
00:00 rue_house carry the infinity...
00:01 katsmeow-afk plus with relays, the space eaten up is so large, the pcb would be gigantic
00:01 rue_house 576 relays
00:01 rue_house cmon, it could heat the house too!
00:02 rue_house 2p2t relays
00:02 rue_house and it would only weigh about 40lbs
00:02 katsmeow-afk so if i keep 16 puters, and put 24 cameras around, and then sprinkle 12 monitors, one or 3 per room, the matrix gets huge, so it must be cheap
00:02 rue_house bugger, none of those cmos chips will work
00:03 rue_house too bad you cant use that reverse diode trick
00:03 katsmeow-afk can use diodes and transistors, again, takes a gigantic qty and alot of pcb space
00:04 rue_house I wanted to try
00:04 rue_house heh,
00:04 rue_house you wouldn't even need multiple female connectors, you could make a gantry for each output
00:04 katsmeow-afk two diodes as a gate and two smt trasnsistrs as buffers ---- per wire, 18 wiers, etc etc etc
00:04 rue_house moves to the right connector and plugs in
00:04 rue_house -----||-----A----|>|------B------||-----
00:05 rue_house the capacitors decouple the dc
00:05 tsmeow-afk
00:05 rue_house you run forward or reverse bias to throw the diode into conduction or not and 'block' the signal
00:05 rue_house ^^ between A and B
00:05 katsmeow-afk i think you'll see the gate signal on the video
00:06 katsmeow-afk it's a 1v video signal, your gate is 0.7v
00:06 rue_house the dc uncoupling would screw it up
00:06 rue_house with the diode biased a few mA into conduction, the signal wont release it
00:07 rue_house it'll just be a .7V dc drop in a dc uncoupled signal
00:07 rue_house if you open it by a few volts, the signal cant turn it on
00:07 rue_house so far its useless, but I think its a neato trick
00:08 rue_house what about a DIY drum switch?
00:08 rue_house x5
00:08 rue_house hey, I have a large bucket of drum switches
00:09 rue_house if you did it backwards,
00:09 katsmeow-afk same issue in a way, for the push-on/pull-off force of the connectors
00:09 rue_house and selected which output the input goes to
00:09 katsmeow-afk if you use wiping, makng it bidirectional could be a big pain
00:10 rue_house I know! use a drum switch to turn relays on and off! :)
00:10 katsmeow-afk also, with drums, you have to jumper each 18-signal x 16 inputs to 5 drums
00:11 rue_house and not witha robot controlled ribbon cable that plugs into one of 16 connectors?
00:11 rue_house oh, I suppose not
00:12 rue_house what if it was a push/pull drum switch that you pull, turn to the right monitor, and then push,
00:12 katsmeow-afk did you know there was a movie in 2014 called automata?
00:13 rue_house when you pull and push it, it makes and breaks with the connectors
00:13 rue_house I didn't know
00:13 katsmeow-afk sure, the pull/push force issue again
00:13 rue_house but by human
00:13 rue_house kitty is sitting on my keyboard
00:13 rue_house I think she wants attention
00:18 katsmeow-afk damn, also: "The Machine" in March 2014
00:20 katsmeow-afk and, holycrap, someone has Tor blocked but royally, if you aren't already conencted to something so your machine knows the dns/ip addy, , you cannot connect
00:21 rue_house gn\
03:17 tsmeow-afk s
03:18 katsmeow-afk these valves may look like 1/4 NPT, but every one needs a good going over with a thread chaser, and a *bottoming* chaser too
03:31 katsmeow-afk 74F283 is 7ns from carry to carry , so an 8bit adder is 7ns from in to out on the lower 4 bits, and then wait 7ns for that carry to go thru the upper 4 bits chip, or 14ns to add two 8bit numbers
03:33 katsmeow-afk same for the 74F181
03:51 katsmeow-afk make it 20ns to account for getting thru the input and output latches, that's 50 million new additions per sec, or a max memory fetches of 50Mhz
03:52 katsmeow-afk clock on a 74F269 is 7ns for essentially adding 1 to the loaded number, or 100Mhz of address generation
03:55 katsmeow-afk worse case clock to output of the 10/100E137 is 5ns , but it's ecl
03:58 katsmeow-afk worse case clock to output of the 10/100E16 is 1ns , but it's ecl, but it's making 1,000,000,000 new addresses per second
04:04 katsmeow-afk rue http://www.ebay.com/itm/Parker-PS1-E10-Valve-Manifold-w-16-PS1-E23-Valve-s-C17-1724-/301505849569
04:08 katsmeow-afk err, 100e016, not 100e16
04:27 katsmeow-afk if i am executing the current instruction in a 20ns timeframe, then the ram is fetching the next instruction at the same time, and the addy generator is calculating the address *after that*
04:28 katsmeow-afk and that's for a measely 50Mips
04:30 katsmeow-afk many instructions don't take 20ns to execute, so if the ram is driven even-odd and outputs at 10ns, the clock is still at 50Mhz, the ram is still 20ns rated, but mips is now 100
04:31 katsmeow-afk but none of that can explain why i am not in bed asleep at 4am
04:34 katsmeow-afk No ce labetha nipakam sahayam saddhim caram sadhu vihari dhiram
04:34 katsmeow-afk Raja' va rattham vijitam pahaya eko care matangarann' eva nago.
04:36 katsmeow-afk http://www.buddha-brothers.com/chapters/chapter-2307.html
04:49 katsmeow-afk i have seen "the machine" somewhere before
07:14 katsmeow-afk lotta robots walking around in Automata
18:35 katsmeow-afk That's what happened to a Spokane, Washington couple after they sparred about their bill with a customer service representative from Comcast. When Ricardo and Lisa Brown got their monthly service bill, the husband's name had been changed from Ricardo Brown to "A**hole Brown."
18:35 katsmeow-afk To make matters worse, Lisa Brown met resistance trying to get the profanity removed and the billing name corrected.
18:35 katsmeow-afk "I'm a bit stunned by this" said Elliott. "Comcast is a big company. They can't control all their employees. But you'd think this is part of the basic training they give to their employees -- don't call your customers a-holes"
18:35 katsmeow-afk well, duh
19:03 rue_house oo thats lots to read
19:04 e_house gets pop
19:07 rue_house manifold" Shipping:$77.80 USPS Priority Mail Express International
19:07 katsmeow-afk yeowche
19:08 rue_house cannot buy from states, has to come from china
19:08 rue_house "If you get a prudent companion (who is fit) to live with you, who behaves well and is wise,
19:08 rue_house you should live with him joyfully and mindfully, overcoming all dangers. [328]"
19:08 rue_house what if I'm a guy?
19:09 katsmeow-afk you hate men?
19:09 rue_house "WANDER ALONE IF THERE IS NO SUITABLE COMPANION" <-- they convered my use case too!
19:09 rue_house no, but I dont want to lifemate one
19:09 katsmeow-afk umm, you may be confusig sex with companionship
19:10 katsmeow-afk you have had male tenants before
19:10 rue_house hmmmmm
19:11 rue_house yea, but
19:11 katsmeow-afk sheesh, what is it with men, everything must point to sex?
19:12 rue_house that wasn't my point
19:13 katsmeow-afk a pin?
19:13 katsmeow-afk pun?
19:14 tsmeow-afk recodes it from "to live" to be "to busin
19:15 katsmeow-afk assuming one lives during business
19:21 Tom_itx is there something wrong with it?
19:22 katsmeow-afk rue was objecting to being alive while near any otehr males
19:23 katsmeow-afk the point of the quote wasn't about "males", itwas about quality of being
19:24 Tom_itx i did quite fine alone
19:25 katsmeow-afk 'better to be alone than be with fools" would be a better translation
19:25 tsmeow-afk looks at
19:25 Tom_itx this damn flippin package has been stuck in chicago since the 25th
19:25 Tom_itx update your friggin tracking.....
19:26 katsmeow-afk customs holding it?
19:27 Tom_itx in chicago???
19:28 katsmeow-afk many of my Canadian packages come in thru chicago
19:28 Tom_itx what about china?
19:28 katsmeow-afk some china ones too
19:28 Tom_itx could be i guess
19:38 tsmeow-afk listens to https://www.youtube.com/watch?v=66yCJ3Sh6og
19:39 katsmeow-afk well, i try to listen to https://www.youtube.com/watch?v=66yCJ3Sh6og , but it keeps cutting out, only chrome will play it, and chrome won't save it to play later
20:00 katsmeow-afk place i worked once, they had no concept of liking something or someone for reasons other than sex, if you wre to like having ducks and geese on a farm, then it was to have sex with them, this also applied to music, if you liked that music, it ws because you wanted sex with that band
20:01 katsmeow-afk strangely, the KKK men still hated hearing women sing
20:02 tsmeow-afk looks at
20:07 rue_house I have no experiance to comment
20:10 tsmeow-afk plays solit
20:15 rue_house so .. is that why you think I build robots then? <8-\
20:16 katsmeow-afk prolly not
20:16 rue_house ok, that feels like progress, I'll stop there
20:17 katsmeow-afk btw, the Automata movie has a 6-legged robot "baby"
20:17 katsmeow-afk it has 2 arms also
20:18 rue_house ah I'm an idiot,
20:19 rue_house I was trying to think of a dump load for a battery bank at work and I couldn't find anything small, I forgot to try thigns filled with water!
20:19 rue_house I think 5kw 240V heaters are available for water tanks
20:19 katsmeow-afk yeas
20:20 katsmeow-afk and the screw-in heater elements arecommon pipe thread, you coule easily make a water basin/pipe/tank with adozen of those heaters
20:21 katsmeow-afk there's a new stove at the recycler every day, you can really score stovetop elements
20:22 katsmeow-afk stack them up in a stovepipe or round duct, with afan at the bottom
20:25 rue_house I need 40A for 12V
20:25 rue_house which is lead-acid 12V
20:25 rue_house so, you know
20:27 katsmeow-afk ok, you need a lot, i'd use whichever you have more of, in my case, that would be the stovetop elements
20:28 katsmeow-afk or you can make somethind with any #10 steel/iron wire
20:29 katsmeow-afk worse case, wait
20:29 katsmeow-afk 0.3 ohms?
20:30 katsmeow-afk 300 ft of #10 copper
20:31 katsmeow-afk 133 ft of #14 copper, but it's gonna get *hot*
20:32 katsmeow-afk try 10 ft of steel electic fence wire
20:32 katsmeow-afk more or less depending on the guage
20:34 katsmeow-afk put 10 2n3055 on a massive heatsink, then you can dial in the exact current load you want
20:37 katsmeow-afk fleece lined boxer shorts?
21:01 katsmeow-afk remember yrs ago, all the hospitals in NY city had generators but no power, because they were flooded, fuel was flooded, or never had monthly powerup tests done?
21:01 katsmeow-afk i found a way to use 2" water pipe as the load resistors up to megawatt loads
21:02 katsmeow-afk they could have hooked the load to the fire mains to kill two birds with one stone by flushing the mains during genny testing
21:04 katsmeow-afk or hooked to the building heat during winter tests
21:05 katsmeow-afk i'm sure no one would be interested in compact water-cooled dummy megawatt-scale loads tho
21:08 rue_house I need a 12V dummy load that cn handle 40A for 10 minutes
21:09 katsmeow-afk [20:09] <katsmeow-afk> 0.3 ohms?
21:09 katsmeow-afk [20:10] <katsmeow-afk> 300 ft of #10 copper
21:09 katsmeow-afk [20:11] <katsmeow-afk> 133 ft of #14 copper, but it's gonna get *hot*
21:09 katsmeow-afk [20:12] <katsmeow-afk> try 10 ft of steel electic fence wire
21:11 katsmeow-afk all i can think is i'd take the opportunity to make a tool i can reuse on other battery powered systems, and that my answer is the worng answer again
21:12 katsmeow-afk everyone has a battery powered system: their car/truck
21:13 katsmeow-afk some of us have big UPSs
21:13 katsmeow-afk but heck, nevermind me
21:13 rue_house solar system in remote areas
21:13 rue_house we have a lot of them up here
21:13 rue_house need to test battery capacity
21:13 rue_house from time to time
21:21 katsmeow-afk and you rig a tester each time?
21:24 katsmeow-afk i don't even care if i win these solitare games any more, i just move the cards around
21:26 Tom_itx i've been there a time or three
21:26 Tom_itx started playing mojang
21:26 katsmeow-afk got to think to play mahjjong
21:27 Tom_itx yeah
21:27 Tom_itx not that much though
21:48 rue_house kat, did you know a whole pot of spagetti water can boil away in just one dr who episode?
21:49 rue_house with the stove on max
21:50 Tom_itx i popped the bottom off a pan once that way
21:50 katsmeow-afk yeas, you did that the other nite
21:51 katsmeow-afk i melted thru a pan that way once
21:53 katsmeow-afk if you use qty10 2N3055, you can test to 50amp@14v and 10a@48v,,,, if you use qty10 MJ1504 you can test to 100amp@14v and 40a@48v AND up to the 56v charge voltage
21:54 katsmeow-afk beware 40amp at 56v is 2,240 watts
21:57 rue_house kat, did you know you cant just eat out of a strainer, they leak...
21:58 rue_house thats the problem I was havng with the dump load
21:58 rue_house but I can impose a limit to just do 12V at a time
21:58 rue_house the banks are 2-6V ... cells....
21:58 rue_house you know what I mean
21:59 katsmeow-afk k
22:01 rue_house this is what happens when we put the world in the hands of users, cells become batteries and groups of cells become battery banks
22:02 rue_house if an idiot had just been kept out of the picture all togethor all the terms wouldn't be screwed up
