00:33 ^kat^ the NORC had a total of 9800 vacuum tubes and 10,000 crystal diodes were used.
00:36 zhanx Crazy
00:39 ^kat^ hi zhanx, i am going to bed now
00:39 ^kat^ gnites
00:40 zhanx Nite, kid just fell asleep so I am sketching code ideas
00:53 nuclearnadal rue_house: ^kat^ the other solder wire on the left side is 60/40
00:53 nuclearnadal http://i.imgur.com/ZhGgnEE.jpg http://i.imgur.com/BGiRRCs.jpg http://i.imgur.com/1HrqRUv.jpg , why the solder look dried and wont melt easily? is the solder wire and flux knock off?
00:53 nuclearnadal oops sorry I was suppose to paste only one link
00:55 rue_shop3 find/borrow a soldering gun
00:55 rue_shop3 the finish on the 60/40 is a bit differeent
00:56 rue_shop3 did the connectors break? your replacing or just soldering them back on?
00:57 zhanx Solder pot is needed
01:06 nuclearnadal rue_shop3: that screenshot I took is after I replaced the usb port
01:07 zhanx Oh sorry didn't read username
01:07 zhanx You need more flux
01:07 zhanx Thought rue was talking to himself
01:07 nuclearnadal zhanx: did you see this screenshot in case you missed it http://i.imgur.com/BGiRRCs.jpg
01:08 zhanx I saw them all
01:09 rue_house waaaaait a min
01:09 rue_house you say the 60/40 wont melt easy?
01:09 rue_house that means your iron is broken
01:10 rue_house its waaaay too cold if it wont melt 60/40
01:10 rue_house you want atleast 260c
01:11 rue_house can you test it?
01:11 rue_house nuclearnadal,
01:11 zhanx Thought it was 265c (I know small difference )
01:12 nuclearnadal i also have one more soldering iron which goes upto 500c and have thick tip
01:12 zhanx Sand it down?
01:12 rue_house If it wont melt the 60/40 its NOT 500c
01:13 rue_house the 60/40 melts around the 260/265 mark me and z are talking about
01:13 nuclearnadal its this one http://baumtronics.com/images/yihua_853D_13_3in1_soldering_station_power_supply_hot_air.jpg
01:14 rue_house no I'm telling you its broken
01:14 nuclearnadal all new stuff cant be broken
01:14 rue_house yes it can
01:14 nuclearnadal everything is ordered recently
01:14 rue_house happens all the time
01:14 rue_house its the modern age, most things are crap
01:14 zhanx Happened to me what 2 months ago rue?
01:15 rue_house it costs less to make things that are faulty and replace when people complain than to make things that work in the first place
01:15 nuclearnadal ok, and can you tell me more about that matchstick test for soldering wire?
01:15 rue_house nuclearnadal, you need to check the iron temp
01:16 zhanx Nuclear, can your iron melt a milk jug?
01:16 zhanx It's pla
01:16 rue_house do you have or know anyone with a high temp thermometer?
01:17 zhanx Rue or materials with a know melting point
01:17 rue_house the 60/40 is what I keep going back to
01:17 rue_house if its having a hard time melting that, its not getting nearly hot enough
01:18 zhanx Which is one of two things
01:18 zhanx Iron or moisture levels
01:18 rue_house nuclearnadal, does the sticker on it say to power it with 110 or 220V?
01:18 zhanx Oh good point rue
01:19 rue_house http://www.aliexpress.com/item/Xilinx-XC9572XL-AMS-CPLD-development-learning-board-test-board-4-programm-LED/2038554034.html
01:19 rue_house should I?
01:19 nuclearnadal all is 110v and is properly connected
01:19 rue_house nuclearnadal, something is wrong with that iron, has to be
01:19 nuclearnadal the point here I am trying to make is that why that loose solder wire is melting properly and that Kaisi and Baku is not melting
01:19 zhanx Fyi you can make a 220v iron 110v
01:20 rue_house yea, the loose solder is prolly a low temp alloy for desoldering or soemthing
01:21 rue_house z, cpld.... ?
01:22 zhanx Rue, never used one but good price
01:22 rue_house http://www.aliexpress.com/item/ALTERA-FPGA-CycloneII-EP2C5T144-Minimum-System-Development-Board-Learning-Board-FZ0697/1807402541.html
01:22 rue_house alteara dosn't seem to be hobbist firendly
01:22 rue_house $$ for software
01:23 zhanx What's your intended use?
01:23 rue_house get into fpga
01:23 zhanx K
01:23 rue_house (yea the other one is a cpld)
01:23 rue_house I have a bunch of $$$ fpga if I can get a working dev system
01:23 zhanx There are boards 100% open source
01:23 rue_house yea, but the baords cost less than the chips
01:24 rue_house its the dev system I need to get happeneing
01:24 zhanx True
01:24 rue_house hmm
01:24 rue_house I'm overloaded in projects right now
01:24 zhanx Google fpga ubuntu hackaday
01:25 rue_house I have the wall clock, the power supply, the new reactor for the boiler, and strippign down the printers that occupy 90% of my 200'^2 deck
01:25 zhanx I have an st link so at least I can program the
01:25 rue_house along with a cnc machine, a second reprap
01:25 zhanx Send me the reprap
01:26 rue_house heh
01:26 rue_house build one with me
01:26 rue_house can you do a $300 budget?
01:26 zhanx Never got my clock parts
01:26 zhanx 300 is alot
01:26 rue_house oh damnit
01:26 rue_house $300 is lots of room for a diy reprap
01:26 rue_house its not even all that diy
01:26 zhanx 25 was my interactive coffee table budget
01:27 e_house
01:27 rue_house wait
01:27 rue_house you want to use $600 of colour serial leds on it
01:27 zhanx No
01:27 e_house folds his arms and frowns
01:27 zhanx 5 dollars of cheap leds on a Rj11 jack
01:28 rue_house "2000 serial rgb leds, maybe more"
01:28 zhanx I said that
01:28 rue_house mmmhmmm
01:28 rue_house iirc I worked it out to more like 5060 for the array you were talking
01:28 zhanx But meant the Rj11 (serial connection )
01:28 rue_house why would each led be on an rj11?
01:29 zhanx Need 2048 works out
01:29 zhanx Rj11 is a quick jack so if it dies quick change no soldering
01:29 zhanx 4 leads
01:29 rue_house ...
01:30 rue_house how about a 4 pin header?
01:30 zhanx It's like a phone jack or rj45 , spacing is off for cost
01:30 rue_house hmm, if I can get off my ass I could print you holders for them all
01:31 zhanx Lots of them
01:31 rue_house must remmeber digits
01:31 rue_house 2048
01:31 rue_house thats more than $24 in plastic tho
01:31 rue_house a roll is $50
01:31 rue_house well, +-, mostly -
01:31 zhanx Well it is 5 bucks from China for them
01:32 rue_house for?
01:32 zhanx Rj11 Jacks
01:32 rue_house 2048 sockets plus plugs?
01:33 zhanx 100 is 2.99
01:33 zhanx Oh wait I dropped a zero
01:33 rue_house 3...6 12
01:33 rue_house ?
01:33 rue_house on which side?
01:33 zhanx My spreadsheet is off
01:33 e_house mumbles "head
01:34 zhanx Miht do thst now
01:37 rue_house http://www.aliexpress.com/item/New-10-Pairs-40-Pin-2-54mm-Male-Female-SIL-Header-Socket-Row-Strip-PCB-Connector/32376257655.html
01:37 rue_house I cant find proper lots of like 50pcs
01:37 zhanx Just need the female ones 4 pin
01:39 rue_house http://www.aliexpress.com/item/2-54mm-distance-between-single-row-seat-Mother-single-needle-seat-Pin-female-socket-1-40p/32275607785.html
01:39 rue_house ok
01:39 rue_house now were making progress
01:41 zhanx I need to settle on my ir sensor also
01:41 rue_house no, use the leds
01:42 rue_house like the video I was pointing you at
01:42 zhanx I kmow
01:42 rue_house leds are cheap
01:42 zhanx Need to test thst still
01:42 rue_house I have the code up, dont I?
01:42 zhanx Yes
01:42 rue_house you reverse charge the led, and measure the discharge time
01:42 rue_house they can take over 250ms to discharge
01:43 rue_house with no light
01:43 rue_house so a leakage resistor might help
01:43 zhanx But will it work at distance reliable?
01:44 rue_house they work as EXTREMELY high contrast light sensors
01:44 zhanx K
01:44 rue_house like huge dynamic range
01:45 rue_house http://ruemohr.org/~ircjunk/tutorials/elex/ledsensor/ledsensor.html
01:45 rue_house most of that code peels down the sensitivity
20:44 rue_shop3 ok
20:44 rue_shop3 I cut holes in the firebo
20:44 rue_shop3 x
20:44 rue_shop3 tommorow I can start working on access ports
20:45 rue_shop3 I need to find two larger tanks for the outter shell
21:53 useless-afk http://leaderpinhead.deviantart.com/art/Artificial-Mind-Short-Story-553026908
21:54 useless-afk i haven't read it yet
22:10 useless-afk good story
23:20 useless-afk using a gaseous helium coolant loop, SABRE dramatically cools the air from 1000 °C down to -150 °C[18] in a heat exchanger
23:21 useless-afk The cooler consists of a fine pipework heat exchanger and cools the hot in-rushing atmospheric air down to the required -150 °C in 0.01s.
23:27 useless-afk The mass of this heat exchanger is an order of magnitude lower than has been achieved previously. The experimental device achieved heat exchange of almost 1 GW/m3, believed to be a world record.
23:28 useless-afk yea,, i'll say, that's ~700 kw per sq inch
23:29 useless-afk The total cost of developing a test rig is estimated at £200M <<== damn, i have never spent that much on a jig
23:40 rue_house iirc helium or hydrogen has a thermal .. thing more than water
23:41 rue_house storage energy..
23:41 rue_house ohohohoh
23:41 rue_house kat, today, I found this, you would love it
23:41 rue_house it turns out that bonnified commercial air-air exchangers for heat recovery, use corriplast!
23:46 useless-afk wow
23:46 zhanx Rent issues
23:46 useless-afk without melting?
23:46 eless-afk has enough issues witout renting
23:47 useless-afk rue, i figured roughly 60,000 btu thru a stack of 10 4x8 , what are they spec'ing them at?
23:47 rue_house you can rent issues now?
23:47 rue_house oh I didn't take a pic of the specs
23:48 useless-afk dija take a pic of the exchangers?
23:48 rue_house I suspect under 1000btu/hr for a unit with an exchanger volume of about 8feet^3
23:48 zhanx 580 rent ETD
23:48 zhanx Kid iemrtpimg
23:48 useless-afk and what are they usng for glue/sealants?
23:48 rue_house I took a pic
23:49 rue_house ETD?
23:49 useless-afk zhanx , i thought you owned the pace you liv in
23:49 rue_house estimated time of departure?
23:49 rue_house I didn't notice the glue
23:49 rue_house thinking...
23:50 rue_house the gooey yellow stuff?
23:50 useless-afk winter is coming you cannot be homeless with kids
23:50 rue_house zhanx, are you saying you came up short for rent?
23:50 rue_house by $600?
23:50 useless-afk zhanx is not providing much info
23:51 rue_house good thing his plates were free
23:51 eless-afk looks conce
23:52 zhanx Sorry kid
23:52 rue_house I'm still trying to understand iemrtpimg
23:53 eless-afk hopes this is not the scam whee the wife moves back close to family and everyone treats the husband real nice riht up till the planned bre
23:53 rue_house I think its what someone says when a cat jumps up on the keyboard
23:53 zhanx Rue paste na scroll back pls
23:53 useless-afk ah, "involuntary utterances"
23:54 useless-afk zhanx , please bring us up to date
23:54 zhanx My kid maxed /smashed all
23:54 useless-afk and rent ?
23:55 rue_house does z need to borrow 0.6k$ from rue?
23:55 zhanx More likem1.2E-2
23:56 rue_house is this related to the bonus you been concerned over?
23:56 zhanx I,e your for clock parts
23:57 eless-afk looks clueless a
23:58 rue_house .012M$ !?
23:59 zhanx Sorry came here to rue about the clock prices
23:59 zhanx Kid gotnin the way etc
23:59 rue_house ok
23:59 rue_house first typing lessons from the sounds of it
