00:16 katsmeow-afk the gotcha is you do not want a large mass of flammable air-fuel mix to accumulate before you lite it, else the melter becomes like a cannon
00:25 katsmeow-afk humans next door shooting guns
00:26 rue_house it must be midnight
00:27 katsmeow-afk midnite +10 minutes, they are a bit slow around here
00:43 katsmeow-afk stinks outside too, the trash fire smoke is not moving
00:44 katsmeow-afk the smoke chills and sinks right backdown to the ground, the neighbors look like they are in a grey fog
00:53 rue_house I hear firecrackers
00:59 katsmeow-afk you hear about the train crash carrying crude oil in North Dalota usa?
00:59 katsmeow-afk dakota
00:59 katsmeow-afk theya re going to use that to jump start the oil pipeline fight again
01:08 katsmeow-afk some of the names at Argonne Nat'l Labs : Dongarra, Bosilca, Herault , Sameer, Shende, Appavoo, Orran, Laxmikant, Ramprasad, Venkataraman, Sriram, Krishnamoorthy, Gioiosa, Gokhale
01:09 katsmeow-afk i'd need spell checker to say hi to anyone
01:10 katsmeow-afk they are now starting to look at computing systems like i envision are needed for economical and smoothly operating robots
01:15 katsmeow-afk wrong : The exascale supercomputers will operate at a speed 1,000 times faster than the current record holder, a machine developed by China’s National University of Defense Technology that performs just under 34 quadrillion calculations per second
01:16 rue_house * calculations must be threadable
01:16 katsmeow-afk if the Chinese puter operated only 30x faster, it would be at 1 exaflops
01:16 katsmeow-afk hmm ?
01:24 katsmeow-afk how *real* computers useto be built : http://www.flickr.com/photos/argonne/8595869474/in/photostream?rb=1
01:26 rue_house "this bits ok, lets check the one before..."
01:27 katsmeow-afk yeas
01:32 katsmeow-afk The arithmetic unit was 10 x 2-1/2 x 7 feet in size
01:32 katsmeow-afk the memory unit 14 x 2-1/2x 4-1/2 feet in size
01:32 katsmeow-afk Memory access time was 15 microseconds
01:33 katsmeow-afk 67 kilohertz
01:35 katsmeow-afk it was necessary, due to problems with the electrostatic memory, to reduce the design 1024 - word memory to 256 words
01:36 katsmeow-afk In an attempt to alleviate the memory problems the Memory Unit was composed of 80 rather than 40 cathode-ray tubes of a different type.
01:37 katsmeow-afk crt ram acted like serial dram, it had to be refreshed as the phosphors dimmed
01:40 rue_house I recall hearing about that
01:41 katsmeow-afk it's basically how scan convertor tubes work, even today when converting ntsc or other 60hz movies to 50hz used in the rest of the world
01:42 katsmeow-afk in the 7912 scope, the writing section charged locations on the target plate, and the read beam on the backside read out the bits, writing could be done at 1Ghz on up to 12Ghz, and readout could be as fast or slow as you liked
01:43 katsmeow-afk programming a 1950's computer : https://www.semiwiki.com/forum/content/attachments/6450d1363116242-13-chloe.jpg
01:44 katsmeow-afk that puter was used till 1970
02:08 katsmeow-afk "the plane will be landing momentarily" "you think we can all get off in just one moment?"
02:16 katsmeow-afk The Xilinx Zynq is the first of these game changers. We all love the low cost Raspberry Pi and BeagleBone Black, but the SoCs on those boards are low end compared to what the Zynq found on the Avnet MicroZed and other boards like the Red Pitaya and the Parallela can do.

08:08 jennie happy new year rue_
09:32 Tom_itx raey wen yppay
12:12 tsmeow-afk rolls things across the open doorway for rue's cats to wonder "wtf was tha
12:26 katsmeow-afk 4000 PCS TEXAS INSTRUMENTS SN74ABT373DWR $25 + $20 2 days
12:26 katsmeow-afk that's 2 full reeels of chips
12:32 katsmeow-afk ouch :
12:32 katsmeow-afk Delivery:
12:32 katsmeow-afk Estimated between Mon. Jan. 27 and Mon. Feb. 24
12:32 katsmeow-afk /ouch
12:33 katsmeow-afk two months delivery, for a recycled part,, they must be sending someone tot he usa to buy a monitor off ebay, ship it by drifting balloon to china, then send the chip back on another drifting balloon
12:34 Tom_itx chinese new year
12:35 katsmeow-afk but why inflict it on everyone else?
12:36 katsmeow-afk it's like,, heck, wait a week to buy, then they'll ship it faster, and i'll get it a week sooner than if i buy it now?
12:36 Tom_itx yup
12:37 katsmeow-afk how to get more excitement than you want: go a mile offshore and shoot bottle rockets
12:38 katsmeow-afk coast guard and homeland screuty will be down on your boat like a ton of humorless bricks
12:41 tsmeow-afk wonders if pulsing hydraulic fluid in a steel line could set up high pressure oscillat
12:42 Tom_itx abs brakes
12:43 katsmeow-afk ok, right conditions for a set up of the situation, but is there oscillations?
12:43 Tom_itx no idea
12:45 katsmeow-afk ok,, related question: how can i measure, in real time, the fluid flow in a fuel injector line?
12:47 katsmeow-afk all i can come up with is to disconnect one and measure it and hope that won't interfere with the operation of the remaining lines, which it undoubtedly will
12:48 Tom_itx at a known quantity from the supply
12:49 katsmeow-afk hmm?
12:49 Tom_itx measure where it goes in, not where it goes out
12:49 Tom_itx oh but you have others to deal with too..
12:50 katsmeow-afk lower pressure, but the recurring rate is 8x faster
12:50 katsmeow-afk yeas
12:51 katsmeow-afk i am pretty sure i have figured out the problem of putting the $900 oem-correct fuel system on the truck, if i can make 100% i won't be introducing new problems
12:52 katsmeow-afk because doing *anything* will cost me lots of time and some money
12:52 katsmeow-afk buggering it up will cost a fortune
12:53 katsmeow-afk spending the $900 for the oem won't necessarily fix it, or fix it correctly ( even that can introduce new bugs too)
13:07 katsmeow-afk someone keeps bidding up 2gb sd cards to $5 , and it's getting on what few nerves i have left
13:14 tsmeow-afk wonders if it wouldn't make for a faster click-to-click cycle time to cache the picture in the camera on bloody fast static ram, and radio it to the fannypack for unlimited mass sto
13:15 Tom_itx i just got good sd cards
13:15 Tom_itx but i also think the camera may buffer as well
13:15 tsmeow-afk
13:16 Tom_itx dunno about the coolpix but i bet the D80 does
13:17 katsmeow-afk i don't need unlimited storage of pics, but it would dovetail nicely with remoting the camera and having easy access to the pics without meddling with a 200ft usb cable to the camera for offloading the pics
13:17 tsmeow-afk has a farm for retired Fuji S700 and Canon
13:19 katsmeow-afk it *can* be cheaper than cheap security cameras, and the zoom will be real handy for reading labels in supermarkets
13:19 katsmeow-afk seems the price break now is tween 10mp and 20mp (working)cameras
13:20 katsmeow-afk that puts the S700 within reach, but the issue is still how to remote the high-def image retrieval
13:21 katsmeow-afk both cameras have continuous ntsc feeds, both record video in ntsc, but that doesn't get you anything if all you have of the intruder that stole everything you have is a ghostly 320x210px image from 20ft away
13:22 katsmeow-afk "do you have a photo of the burglar?" "yes, he is these 6 pixels right here!"
13:25 katsmeow-afk "i can see someone approaching from a mile away" "yeas, but can you tell the difference tween the jelly and peanut butter jars in each gripper?"
13:26 tsmeow-afk isn't going to experiment with a camera over $5, or buy an sd card ove
13:26 katsmeow-afk winter is mostly indoor playtime, and technically winter has just begun
13:29 tsmeow-afk puts a ittybitty $9 camera tween the fingers of rue's lil'est robot arm so it can zoom/home in on parts and see what they
13:30 katsmeow-afk " the cmd 'if it does not move, paint it' does not apply to the cats"
13:34 katsmeow-afk "i can read the finest print in the ingredient list on any jar in here from one foot away!" "you just ran over that kid" "he was over one foot away"
13:36 katsmeow-afk you may recall that guy's camera that was an array of image sensors 5ft(?) diameter, aimed at a rotating camera in the center, so each camera took an image once, but all clicked in in about 2 seconds?
13:37 katsmeow-afk only way i know to do that in a robot's head is store an hdtv movie, but the price is still too high, and there's still the issue of how to get the movie out of the camera instead of it being stored in the sd card
13:40 tsmeow-afk ponders a physically moving pixel mask that the camera electronics is sync'd to, such that the hole in the mask just barely leads the readout address strobe of the image se
13:41 katsmeow-afk that way the camera effectively becomes a one-pixel detector, and the pixel position on the image is the time-location over the 'click' duration
13:42 katsmeow-afk subject to the physics limits on the movement of the mask, naturally
13:43 tsmeow-afk lays out a row of fiber optic lines in a row around a circle and drills a .005 hole in a disk to unmask one fiber at a
13:46 katsmeow-afk then each fiber is lit up just before the camera reads that location when it scans the image sensor during readout
13:47 katsmeow-afk that's 300k dots per frame, times 30 frames per sec for ntsc, or an analog bandwidth of 9msps ...... :-/
13:48 katsmeow-afk if you used 300 cameras tho, that's still 900,000 ntsc pictures per second
13:49 tsmeow-afk growls somet
13:56 katsmeow-afk The company also points out to the passengers suing that the cruise line never promised a safe trip.
13:56 katsmeow-afk Carnival's court filing says the "ticket contract makes absolutely no guarantee for safe passage, a seaworthy vessel, adequate and wholesome food, and sanitary and safe living conditions."
13:56 tsmeow-afk growls something
14:05 katsmeow-afk of the *6* generators onboard, 3 were overdue for overhaul, and *none* were in safe operating compliance
14:06 katsmeow-afk which is why they all caught fire and died
14:08 katsmeow-afk "so you are saying we can get 3 up-to-date now for $10k, and rebuild the other 3 for $120k, OR.. we can replace them all as scrap junk next week for $12,000k (plus the cost of towing the powerless ship full of poop for 3 days)?"
14:39 tsmeow-afk comes back inside for a berath of fresh
14:58 tsmeow-afk still wonders if one could get a 1280 x 800 3megapix image in real time out of a 3mp camera just by hacking the clock and ram and speeding up
14:58 katsmeow-afk or 1024x768 , etc
14:59 katsmeow-afk 1024 x 768 isn't even one megapix
17:55 rue_house kat, I'm wondering if the high temps are killing the sensors, it gets in excess of 80c in there, I wonder if the transistors start leaking and screw up the digital switching
17:55 rue_house the new harddrive is hanging by its wries, all be back after a reinstall...
18:00 katsmeow-afk possibly
18:01 katsmeow-afk lm35 : Rated for full -55° to +150°C range
18:03 Tom_itx mmm
18:03 Tom_itx i forgot how to implement a multidimensional array and access it
18:04 katsmeow-afk object x = {{},{},{}}
18:04 katsmeow-afk or
18:04 Tom_itx different language
18:04 Tom_itx might be the same though
18:04 katsmeow-afk object x = {repeat({},30),repeat({},30),repeat({},30)}
18:04 katsmeow-afk etc
18:05 katsmeow-afk object x = {{},{},{}}
18:05 katsmeow-afk object y = {x,x,x}
18:05 katsmeow-afk what language?
18:05 Tom_itx compiled dbase... clipper
18:05 Tom_itx old dos based program
18:05 katsmeow-afk oh,, dunno
18:06 Tom_itx basically pascal
18:06 Tom_itx i think i'll just use single dimension arrays
18:06 Tom_itx it would be too hard to edit in the future
18:06 katsmeow-afk i have not used pascal since the early 1990's
18:07 Tom_itx well it works as it is
18:07 katsmeow-afk i kept running into limited stack space, line length limits, and 64k pages
18:07 Tom_itx and will be simpler to edit now
18:07 Tom_itx this swaps to memory
18:07 Tom_itx kinda nice really
18:07 rue_house zlog
18:08 katsmeow-afk swaps to memory? itn't it in memory?
18:08 Tom_itx the exe is 530432
18:08 Tom_itx extended or whatever
18:09 Tom_itx i can't even remember it's been so long
18:09 rue_house for your parts database?
18:09 Tom_itx no for my work database
18:09 Tom_itx payroll
18:09 Tom_itx i enter the fed tables
18:09 Tom_itx and it pays me
18:10 Tom_itx but i've always edited the functions, now i just edit an array
18:10 Tom_itx once a year
18:10 Tom_itx been gonna make the change for years
18:10 Tom_itx but never did
18:17 tsmeow-afk ponders di
18:23 Tom_itx hardly worth doing the state one it's so short
18:42 katsmeow-afk some fool went and scheduled us for 22F tomorrow nite, then a couple days in the 30's, and 12F Monday nite
18:42 katsmeow-afk temps like that will make it impossible to work upstairs :-/
18:42 katsmeow-afk i guess winter has arrived
18:47 katsmeow-afk i spose i shall go up and grind/weld some steel tonite after dinner
18:51 rue_house I have to regrind the iron behind the jaws of my vise, they didn't take off enough and, from the casting, its still )( I got a new jaw to replace the broken one, but it I dont fix this it'll just snap again
18:52 Tom_itx yep, temp is dropping like a rock here
18:57 katsmeow-afk rue, if you could put up a dense line of windmills from the rockies to mid-Quebec, blocking some of this cold and making some electricity, we'd appreciate it
18:58 rue_house hmm
18:58 rue_house the great millwall of canada?
18:58 katsmeow-afk yeas
18:59 katsmeow-afk all that elecyricty = no need for oil sands
18:59 rue_house cost less too
19:01 tsmeow-afk hands rue a Round
19:02 Tom_itx enough with this friggin paperwork
19:02 rue_house cant use it now, I'd wake the neighbours
19:02 katsmeow-afk the "paperless office" , Tom
19:02 Tom_itx when has that ever stopped you?
19:02 rue_house huh, last I saw i was trying to etch a board...
19:03 katsmeow-afk how noisy can etching a board be?~
19:03 rue_house no I was reffering to building 300' windmills
19:03 katsmeow-afk make em shorter, make em where you need them to be 300', saves transportation costs
19:04 rue_house I jus assumed make them in 39' sections
19:04 rue_house so they fit in 40' containers
19:04 katsmeow-afk make em foldable
19:04 rue_house hah, I thought that said affordable for a sec
19:05 katsmeow-afk need a way to put all that rotary power in the nacel, down on the ground anyhow
19:05 katsmeow-afk silly to put 100 tons of generator up on top of the tower
19:06 Tom_itx belt drive
19:06 Tom_itx long ass belt
19:06 Tom_itx hydraulic
19:07 Tom_itx too much loss
19:07 Tom_itx already too much loss in the transmission lines
19:07 katsmeow-afk hydraulics would be the way to go, imho, it would give you rotary couplings and "gear ratios" too
19:08 katsmeow-afk but you can't consider hydraulics as 100psi stuff, the weight of the lines and pump would be enourmous
19:08 Tom_itx they are made to be fairly 'maintenance free'
19:08 katsmeow-afk err, i meant 10000psi
19:08 Tom_itx loss keeping the pump running
19:08 katsmeow-afk make it 100 psi, high volume, make the tower be the tank, the hydraulic motor at the bottom
19:09 katsmeow-afk 12" pipe down to the hydraulic motor
19:09 katsmeow-afk or bigger
19:11 katsmeow-afk you gotta wonder how much losses there are in gearing a 60rpm set of blades up to 900rpm or higher to make electricity
19:11 Tom_itx big gears too
19:12 katsmeow-afk and heavy
19:12 Tom_itx i wonder how many steps they make it in
19:12 katsmeow-afk prolly a trade secret, i have never seen data on that
19:12 Tom_itx the factory is about 50 mi from here
19:12 katsmeow-afk you have not visited and taken pics yet??
19:13 tsmeow-afk paypals Tom $20 for
19:13 Tom_itx nope
19:13 Tom_itx doubt they give tours
19:14 katsmeow-afk put on a osha hat and walk in like you own the place, ask for your own name, in a dept you are not currently standing in but want to goto next, say it's urgent
19:15 katsmeow-afk how do you think i got thru Network Solutions security?
19:18 katsmeow-afk the solar plant in Ga didn't give tours either, so i started my own and an engineer came out and spent an hour showing me everything
19:19 katsmeow-afk ditto a power generating plant of Ga Power
19:20 katsmeow-afk about the only place i would not advise walking into like that is a place where they *want* to shoot you
19:20 katsmeow-afk the post office, for instance
19:23 katsmeow-afk i told ya i went onto a city supply depo in Fla, two cop cars where there, loaded with cop, and they offered to help me do whatever i was there for
19:25 katsmeow-afk <shrug> you can always ask, as the reporter for your local newspaper, your *really* local, in-house printer yourself, news paper for your family
19:29 katsmeow-afk "we had a paid circulation of 2,000 last month" (5 cents and 2,000 characters on the page)
19:32 katsmeow-afk comeon, Tom, it's not like you're the next Ed Snowdon
19:35 katsmeow-afk Florida-based Project Cure has raised more than $65 million since 1998, but every year has wound up owing its fundraiser more than what was raised. According to its latest financial filing, the nonprofit is $3 million in debt.
21:09 rue_shop3 1kg water, 250g etchant mix
21:10 rue_shop3 so, I ahve to rescale so the result is 1kg
21:12 Tom_itx 4:1 right?
21:12 rue_shop3 but the result has to be 1kg
21:12 Tom_itx why?
21:12 rue_shop3 because otherwise it wont fit inthe damn bottle
21:12 tsmeow-afk needs a way to stay unsweatywet with a lite sweater on (to shield from hot steel spray) when it's so cold she can see her br
21:12 Tom_itx get a bigger bottle
21:12 Tom_itx i used a 2 litre pop bottle
21:13 rue_shop3 no, if I figure this out again, I can mix it right the first time
21:13 katsmeow-afk good thing about 2Liter pop bottles: there's always plenty more
21:13 Tom_itx you go thru this every time
21:13 rue_shop3 I know
21:13 Tom_itx you should have it !bookmarked by now
21:13 katsmeow-afk or postitted
21:13 rue_shop3 I wish I know where I kept putting the answer
21:13 rue_shop3 oh wait
21:14 katsmeow-afk laminate the answr with clear packing tape, then secure to the handle of the important relavant bottles
21:14 Tom_itx naw
21:15 Tom_itx that make sense
21:15 rue_shop3 nope
21:16 rue_shop3 I once put the answer on the bottle, it faded off
21:16 katsmeow-afk cut tags out of clear 2L bottles, laminate the answer tween them, drill hole, tyrap to bottle
21:17 rue_shop3 800g water to 200g crystal
21:17 rue_shop3 so for my 2L bottle I do 1.6kg and 400g
21:18 katsmeow-afk not using muratic and peroxide then?
21:18 Tom_itx persulphate
21:18 rue_shop3 the scale went missing...
21:19 katsmeow-afk you got all those nice shelves, and things go missing? maybe that huge long jackscrew arm took them
21:22 rue_shop3 it was used for ebay stuff, I cant find it now
21:22 katsmeow-afk what is the lifetime on those tiny camera sd cards?
21:23 katsmeow-afk i have never had one fail, but then i never filled one up
21:23 rue_shop3 never had one fail
21:24 rue_shop3 and I dont know how to get the bad/spare block count from them
21:26 katsmeow-afk Are you sure that it isn't a fake 32GB?? (If you didn't by it from a retail store)
21:26 katsmeow-afk If it was bought from Ebay, its probably fake like the one I just got and won't work right at all, or at least won't store more than about 2GB's of data
21:26 katsmeow-afk but that sounds like the issue of the SD vs SDHC
21:27 katsmeow-afk my newest camera, a 5yr old S700 will not take SDHC, so won't do but 2G anyhow, but that's a ton of pics, and the guy posting was talking about a phone
21:30 katsmeow-afk http://www.bunniestudios.com/blog/?p=918
21:39 katsmeow-afk (the Samsung controller is a 32-bit ARM7TDMI with 128k of code),
21:44 katsmeow-afk http://www.bunniestudios.com/blog/?cat=6
21:45 katsmeow-afk Today at the Chaos Computer Congress (30C3), xobs and I disclosed a finding that some SD cards contain vulnerabilities that allow arbitrary code execution — on the memory card itself. On the dark side, code execution on the memory card enables a class of MITM (man-in-the-middle) attacks,
21:45 katsmeow-afk etc
21:45 katsmeow-afk On the light side, it also enables the possibility for hardware enthusiasts to gain access to a very cheap and ubiquitous source of microcontrollers.
21:47 katsmeow-afk in China, I’ve seen shop keepers burning firmware on cards that “expand” the capacity of the card — in other words, they load a firmware that reports the capacity of a card is much larger than the actual available storage.
22:00 rue_shop3 there is a ted talks on youtube about it
22:00 rue_shop3 he found a site that he could download the untility that lets you select, among other things, the card size, and if it overwrites or not
22:02 rue_shop3 dropdown menus
22:02 rue_shop3 also allows you to upload/download the firmware
22:04 rue_shop3 hmm, my first board plotted with nailpolish resist didn't come out toooo bad
22:05 katsmeow-afk i been wondering about those fancy nailpolish painting pens
22:06 katsmeow-afk "Sectors in SLC memory typically fail after 100K writes, sectors in MLC memory typically fail after 1K writes, however sectors in 3-Bit MLC memory appear to fail after only 10 writes."
22:07 katsmeow-afk "Until that happens always assume any flash device 8 GigaBytes and over uses 3-Bit MLC memory."
22:08 katsmeow-afk Tom, re the 2gb limit : "Many flash controllers (UFD, SD, and CF) are not optimized for NON-FAT32 filesystems. Reformatting your flash drive with a different file system (eg: NTFS or exFAT) can cause the drive to fail or degrade performance."
22:08 katsmeow-afk http://rufus.akeo.ie/
22:10 tsmeow-afk ponders some wire brushing to make dust, and some welding to make
22:11 Tom_itx ewww
22:12 Tom_itx to the "Reformatting your flash drive....
22:12 rue_shop3 I repartitioned a usb drive and it would not go back togethor like it was origionally
22:14 Tom_itx humpty dumpty
22:15 rue_shop3 sat in the fall!
22:16 rue_shop3 humpty dumpty had it all
22:16 rue_shop3 humpty dumpty had a great wall!
22:30 rue_shop3 yay! 10 class A fet drivers
22:51 katsmeow-afk oh my sore paws
22:53 rue_shop3 ok, not bad, its got a turn-off time of 10uS
22:53 rue_shop3 us
22:53 katsmeow-afk that's a long time for a bipolar
22:53 rue_shop3 mosfet
22:53 rue_shop3 class A gate driver
22:54 tsmeow-afk is not accustomed again yet to keeping a death grip on a grinder or brush for so
22:59 rue_shop3 1206 resistor is rated for 1/4W
23:00 rue_shop3 so I could go down to 580R
23:00 katsmeow-afk so they claim'
23:00 rue_shop3 I'm at 1k now
23:00 rue_shop3 http://www.bourns.com/data/global/pdfs/CHPREZTR.pdf
23:00 rue_shop3 bourns should be realiable
23:02 katsmeow-afk but they also haveto sell resistors, and you know how hot a axial leaded 1/4 watt gets at 1/4 watt? imagine it being 1/8 the size and still tryig to dissipate 1/4 w
23:03 katsmeow-afk ah, there is the gotcha : power rating at 70c, seconds after you put 1/4 watt into it, it's not at 70c anymore, it's overheated
23:03 rue_shop3 oh! ho ho!, the pulldown resistor is the ONLY one thats not smt!
23:04 katsmeow-afk for crips sake, use a real current source, make life easier on the pullups!
23:05 katsmeow-afk 1000hr Load Life +70 °C; 1.5 hours on, 0.5hrs off, 1000hrs
23:12 rue_shop3 huh, a 520R resistors chunked across 12V dosn't really get that hot
23:12 rue_shop3 kat, its a .6"x.6" board
23:13 rue_shop3 its got 5 resistors and 2 transistors
23:13 katsmeow-afk k, pics when it's doned
23:13 rue_shop3 it uses a common emitter npn to trigger a pnp off the 12V, with a pulldown resistor
23:13 rue_shop3 its donned! I'll take pics in a min
23:14 katsmeow-afk you have a resistor tween the npn-e and the pnp-b ?
23:14 katsmeow-afk errr
23:14 katsmeow-afk you have a resistor tween the npn-c and the pnp-b ?
23:16 tsmeow-afk wonders if you use a resistor to pull the gate up, a couple diodes to the ttl signal, the ttl can pull the gate down to 3.5v and let it go up to
23:17 katsmeow-afk the mosfet is off at 3.5v, and prolly full on at 6.5
23:17 katsmeow-afk at least for 4 amps
23:18 katsmeow-afk that saves you two transistors, unless you wanna make one of the diodes a pnp
23:23 rue_shop3 hold up, I'llpost it all
23:29 katsmeow-afk STORY HIGHLIGHTS
23:29 katsmeow-afk Current spending levels are authorized through January 15
23:29 katsmeow-afk We run out of money again on February 7
23:32 katsmeow-afk The real power is coming in 2014 in the form of the Arria 10 SoC. Packing a 1.5 GHz dual ARM Cortex-A9 and up to 660K logic gates implemented in TSMC 20nm, the Arria 10 really gets into the programmable SoC game. The allure of a fast multicore engine running Linux or an RTOS combined with fast transceivers and gates for DSP and other functions is irresistible.

23:38 tsmeow-afk put a 600w heater in this room, first time it's had a heater in it in 4 or 5 y
23:48 tsmeow-afk figures rue fall asleep and goes back up to grind and brush and maybe p
23:51 rue_shop3 nono, just wrapping up shop
23:54 rue_house between the smt parts, and foling the transistors over, this came out really nice and small
23:58 rue_house hahah, its not 2013 anymore, my camera unloading script just backfired on me
23:59 rue_house SWEEET I already started apower supply project and I think the new parts will fit into it!
