00:08 rue_house I'm back!
00:08 rue_house the truck only cost $100 and something
00:08 rue_house turns out the plugs, rotor and cap were shot
00:08 rue_house :)
00:09 orlok heh, thats likely what i do on the car next
00:09 orlok it doesnt like it when its cold
00:09 rue_house I dont know how often those should be attended to
00:10 orlok "it depends" heh..
00:10 orlok points? or electronic?
00:10 rue_house I changed the plugs not long ago, and last I recall the rotor and cap were in great shape
00:10 rue_house electronic
00:10 orlok i replaced my points with an electronic setup as soon as i could..
00:10 orlok since then i think the distributor gears broken more often than i have replaced the other stuff
00:11 rue_house break?
00:11 rue_house breaking a gear requires torque
00:11 katsmeow-afk there's distributor gears?
00:12 rue_house the spline ones that rotate the rotation 90 degrees
00:12 katsmeow-afk umm, if you say so
00:12 rue_house off the crank?
00:13 rue_house the rotor is driven off a thing thats perpendicular to the crank
00:13 katsmeow-afk distributor and oil pump get driven off the camsshaft too
00:13 rue_house mines really low, I'm sure its off the crank
00:14 rue_house :( I have to go to bed now
00:14 e_house cleans his teeth for a mi
00:16 katsmeow-afk "The rotor is attached to the top of the distributor shaft which is driven by a gear on the engine's camshaft and thus synchronized to it. "
00:16 katsmeow-afk " Often, the rotor and distributor are attached directly to the end of the one of (or the only) camshaft, at the opposite end to the timing drive belt."
00:19 katsmeow-afk "Reducing pump speed is beneficial[note 2] and so it is usual to drive the pump from the cam (if this is mounted in the cylinder block) or distributor shaft, which turns at half engine speed. Placing the oil pump low-down uses a near-vertical drive shaft, driven by helical skew gears from the camshaft."
00:19 tsmeow-afk knows for a fact the olde 289 uses a common shaft at 90 degrees to the camshaft to drive the oil pump and distrib
00:21 rue_bed what about the "iron duke"
00:21 rue_bed 4 cyl inline
00:22 rue_bed 2.4 (?) L
00:22 katsmeow-afk i dunno
00:22 katsmeow-afk http://en.wikipedia.org/wiki/GM_Iron_Duke_engine
00:22 rue_bed I'd like a blowup of my engine, have a stick of dynamite?
00:24 katsmeow-afk i am disappointed the hp of this 6.5L diesel is only 200hp, and that is if the right injector pump is on it and the turbo is working
00:25 katsmeow-afk considering the Prob'e 2.4L turbo is 135hp, and the 280zx (2.8L) is 135hp also, 6.5L should be 250hp
00:26 katsmeow-afk at least, even non-turbo'd
00:26 katsmeow-afk really, the 351cuin gasburner 4bbl is over 200hp
00:27 tsmeow-afk s
00:27 rue_bed hey, sounds like I can get a distributorless kit for it
00:28 katsmeow-afk you need such a thing?
00:28 rue_bed The Tech IV uses the same bellhousing pattern as the 2.8 L 60-Degree V6.
00:29 rue_bed aha, that can help me find the std transmission I need for my electric conversion
00:30 katsmeow-afk umm, if you are going to swap the engine for a motor, the autotranny for a manual, why do you need to keep the same bell housing?
00:30 rue_bed When the cam gear loses a tooth, the camshaft AND distributor stop rotating during engine cranking
00:30 rue_bed I cant deny it now can I?
00:30 katsmeow-afk hmm, what?
00:31 rue_bed I presume the bell has the mounting ... wings
00:31 rue_bed this engine definitly runs the distributor off the cam
00:31 rue_bed which I find odd, cause its really really low
00:31 rue_bed oh, of course it is
00:31 rue_bed its not overhead cam
00:31 rue_bed hahaha
00:32 katsmeow-afk nah, most mounting is done with two on the engine and one under the tail of the tranny
00:32 rue_bed OOo,...
00:33 katsmeow-afk so if you wanted, if you did get a manual tranny, bolt up the motor as you want, and site the motor mounts to the chassis once you get the tranny tailpiece mount bolt in
00:33 tsmeow-afk put an electric motor on a VW beatle many many yrs
00:34 katsmeow-afk seriously??? http://www.ebay.com/itm/TEKTRONIX-7603-OSCILLOSCOPE-/150726048148?pt=BI_Oscilloscopes&hash=item2317f8f994
00:34 rue_bed thanks kat, somehow my last round of research didn't turn up that wiki page
00:36 katsmeow-afk <curtsey>
00:36 rue_bed hahaha 139!!!!
00:36 rue_bed hahahaha
00:36 rue_bed how about $2
00:36 rue_bed !
00:36 rue_bed hahahaha
00:37 katsmeow-afk and $158 shipping
00:38 katsmeow-afk there's a 7603 for $9 too
00:39 rue_bed one not run over by a forklift?
00:39 katsmeow-afk it's got problems
00:39 rue_bed dont we all
00:39 rue_bed er
00:40 katsmeow-afk crt may be bad, the 7b92a was dropped on it's face
00:40 katsmeow-afk it's not gonna power up with a trace with the plugins in the wrong slots anyhow
00:40 rue_bed more boken tek knobs
00:40 katsmeow-afk $38 s&h to me
00:41 rue_bed with even more broken knobs due to packing I bet
00:41 katsmeow-afk $47 total,,,, if i needed another 7a26, and parts, it would be worth it
00:42 rue_bed I think I found a connector for the card I have
00:42 katsmeow-afk the 7a26 looks ok, no clue if it's working tho
00:42 rue_bed for the more advanced one
00:42 katsmeow-afk and i have like 10 of them
00:42 rue_bed I need to make a power supply too
00:43 katsmeow-afk it has a 7B92a, i prefer the 7B92
00:43 katsmeow-afk http://www.ebay.com/itm/TEKTRONIX-7603-OSCILLOSCOPE-7B92A-AND-7A26-PLUG-INS-PARTS-NOT-WORKING-/390393092672?pt=BI_Oscilloscopes&hash=item5ae53dda40
00:44 katsmeow-afk hasn't been used in forever, it has mold on it
01:17 home wth is an fPGA 0_0
02:02 Wulong home: field programmable gate array if I recall correctly.
02:15 theBear sounds about right, close enough anyway
02:22 Wulong It's just a fancy name in my ears. It's a hell to work with.
02:24 theBear sure looks a lot different to anything else, but damn, if yer get even half-good with them all of a sudden you got this whole world of things/projects you can do that you wouldn't even consider 'diy'ing previously
02:25 Wulong orly
02:25 Wulong In my experience FPGA is just bunch of constraints.
02:26 Wulong Atmel and C-kode is way better.
08:46 rue_house you have to be good with state machines
08:46 rue_house most people dont understand them at all
10:19 katsmeow-afk fpga is a hardware way of doing really fast stuff, like interfacing cpus to other hardware, or even programming the fpga to be a cpu
10:22 katsmeow-afk there are C libs that make some fpga be various cpus, like 6502, z80, avr, arm, etc.. see: http://www.google.com/search?q=fpga+cpu
10:26 katsmeow-afk Examples of such hybrid technologies can be found in the Xilinx Virtex-II PRO and Virtex-4 devices, which include one or more PowerPC processors embedded within the FPGA's logic fabric.
10:26 katsmeow-afk The Atmel FPSLIC is another such device, which uses an AVR processor in combination with Atmel's programmable logic architecture. The Actel SmartFusion devices incorporate an ARM architecture Cortex-M3 hard processor core (with up to 512kB of flash and 64kB of RAM) and analog peripherals such as a multi-channel ADC and DACs to their flash-based FPGA fabric.
10:27 katsmeow-afk By incorporating the ARM processor-based platform into a 28 nm FPGA family, the extensible processing platform enables system architects and embedded software developers to apply a combination of serial and parallel processing to address the challenges they face in designing today's embedded systems, which must meet ever-growing demands to perform highly complex functions.
10:29 katsmeow-afk http://en.wikipedia.org/wiki/Reconfigurable_computing
13:02 katsmeow-afk "A study has shown that designs implemented on FPGAs need on average 40 times as much area, draw 12 times as much dynamic power, and are 3 times slower than the corresponding ASIC implementations.[24]
13:02 katsmeow-afk but you can buy a fpga for under $20, as opposed to getting an asic to your specs for over $20,000
13:53 rue_bed MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMNnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn
13:54 Tom_itx git yer darn kat off the kbd
15:03 katsmeow-afk mow?
15:04 katsmeow-afk mouw mowe moew?
15:04 katsmeow-afk is rue sick?
15:15 katsmeow-afk ACTION still has a barely controllable urge to slap the sheet out of M$: "do you want to esign this game?" "no"..."close game" "do you want to resign this game?" "i said no, now close the game" "do you want to resign this game?" "my wants and desires are irrelavant, you are a machine, close the game" "do you want to resign this game?" "no damnit, i don't, but i have other things to do, close the game" "do you want to resign this game?" /me y
17:05 SolarNRG Hi guys
17:05 SolarNRG I have a new youtube video
17:06 SolarNRG Its me trying to melt bean cans into gears
17:06 SolarNRG Its for my robotics project
17:06 SolarNRG I want to show you all so you can help me figure out how to improve the method
17:06 SolarNRG http://www.youtube.com/watch?v=VSKl1konZ0U
17:09 Steffanx YAy
17:10 effanx waits for a
17:12 Steffanx No boom :(
17:13 SolarNRG Yes I know
17:13 SolarNRG But no melt either
17:13 SolarNRG All that seemed to happen was a corner got partially cooked
17:14 SolarNRG Do you know how I can improve this method so the ally melts?
17:21 Steffanx No, not really
17:23 SolarNRG :(
17:50 Tom_itx that's just silly
17:50 SolarNRG Why?
17:50 Tom_itx rather dangerous
17:51 Tom_itx make a proper crucible with fire brick and use kero or charcoal
17:51 Tom_itx rue has done it
17:59 SolarNRG Well I'm trying to do it without burning anything to lower my pollution levels
17:59 SolarNRG Also is autodesk inventor any good?
18:11 techb hello all
19:32 rue_house they did the field flush, they say that the septic field is pooched
19:33 rue_house no I used vermitulite and concrete
19:33 rue_house ver cim ul ite
19:33 rue_house no
19:33 rue_house my fingers are making up letter
19:33 rue_house try pecking it
19:33 rue_house vermiculite
19:33 rue_house there we go
19:35 rue_house why aren't people making tricopters?
19:38 rue_house and didn't someone already point out that 1 blade copters are more efficient?
19:40 rue_house ok I had to go to a mcdonalds to fix two cables, one was obvious and the other they didn't know what cable they wanted fixed
19:40 rue_house as I didn't want ot fix every cable in the whole place I left them saying they would get back to me
19:41 rue_house NOW after work, I get an emergency call
19:41 rue_house ugh
19:52 katsmeow-afk what's a "resuce dog" ? ==>> Denver News Anchor Kyle Dyer was Bitten by a Resuce Dog Live on TV
19:53 LoRez a dog that's been "rescued" from the pound I'd think
19:54 katsmeow-afk funny thing, if a drunk man had beat her up and caused her to need 70 stitches and surgery and her mouth wired shut (she's a tv reporter), i don't think she'd be dismissing the injury so casually
20:02 Tom_itx does mcdonalds fry cables too?
20:03 katsmeow-afk you never had an overly chewy french fry there?
20:03 rue_house mcdonalds uses telephone cord for a bunch of their systems, things go wrong all over the place
20:04 katsmeow-afk sending batteries via USPS: Power Over Post Office Protocol
20:04 rue_house hehehe
20:04 rue_house popop
20:05 Tom_itx rue_house
20:05 Tom_itx turn your fireshed into an outhouse
20:05 rue_house I'm not ogint o call mcdonalds till it gets dark
20:05 rue_house its plumbing leaks more than the septic field right now
20:06 katsmeow-afk if the septic field leaks, why won't it drain?
20:06 rue_house it dosn't
20:06 rue_house thats the problem
20:06 katsmeow-afk they won't freaking frack it?
20:06 rue_house there is a coupling int eh boiler system that leaks about a cup a day
20:07 Tom_itx ok so what about the truck?
20:07 katsmeow-afk i say you put a 180psi firehose to it, it WILL start draining
20:07 rue_house they sent a powerwasher down it, no go
20:07 rue_house the truck only needed new rotor and cap, its happy
20:07 rue_house "please stand back, sewer guisers are normal"
20:07 katsmeow-afk washing it won't help, you need to open it with lottsa pressure and volume
20:08 Tom_itx call the fire dept
20:08 Tom_itx tell them there's a fire in that hole over there
20:08 rue_house the plan is to add a temp illegal run
20:08 katsmeow-afk 1) make a robot, 2) load it with M-80's, 3) have it stick one in each perf in the perfpipe in the field, 4) light them
20:08 Tom_itx well i hear sh** runs downhill so don't aim it this way
20:09 rue_house heh, fill the pipe with an ignighter and 50/50 propane/oxygen
20:09 Tom_itx just tie some detcord to the behind of your bot and kiss it goodbye as you send it off down the pipe
20:10 katsmeow-afk but seriously, if you can put a drill on it with a flex drive, bore holes thru the existing holes in the perfpipe into the field, it should be almost like new again
20:10 rue_house that or shell out $20000 for a new system
20:10 tsmeow-afk hereby patents the idea, you know where to send royal
20:10 Tom_itx naw
20:10 Tom_itx put that toward a new house
20:10 rue_house I should be abel to dig up the end
20:11 rue_house the new house includes having to do a new sytem anyhow
20:12 katsmeow-afk ok, then a waterjet thru the existing holes into the drain field, and you know where to send my royalties
20:13 katsmeow-afk use your ductbot
20:13 rue_house you have me thinking of making an adapter for the pipe end to a high pressure hose fitting
20:14 katsmeow-afk yeas
20:14 rue_house 80psi should be enough
20:14 rue_house and I have access to the pipe ends, for now
20:14 katsmeow-afk lotsa holes, i'd use as high a pressure as possible
20:15 katsmeow-afk any sand etc that blows out of the holes, you haveto remove, but you'll have the water to do that too
20:15 rue_house 80psi over 400 square feet will push out soemthing
20:17 Tom_itx keep your mouth shut when you let it blow
20:17 katsmeow-afk umm, by "holes", you know i mean the perfs in the perfpipe, right? that's what you're aiming at primarily, to open up the field draining again
20:18 rue_house they say it'll be saturated with oil
20:18 katsmeow-afk which you'll blow holes into/thru
20:18 rue_house should do yea
20:19 rue_house your idea worked good to clean up the board
20:19 rue_house I have a nice clean unused corner tho :/
20:19 katsmeow-afk board?
20:19 rue_house that pcb
20:19 katsmeow-afk o
20:21 e_house th
20:21 rue_house its dark
20:21 rue_house *sigh*
20:21 rue_house cats in, mcdonalds, prep robotics sleep, robotics, lunch, shopping, then I get free time
20:21 rue_house to go dig up the septic system
20:21 katsmeow-afk scary time to be in a McDonalds, eh?
20:21 rue_house OH YEA! THATS WHAT i WANTED TO DO!
20:22 rue_house !assist circuits/olpcb.png
20:22 tobbor Possibly http://eds.dyndns.org/~ircjunk/circuits/olpcb.png
20:23 rue_house the 5V line is being really annoying
20:23 katsmeow-afk you can save another .1 off the top by moving the molex to the right and down
20:24 katsmeow-afk which one is +5?
20:25 Tom_itx rue_house
20:25 Tom_itx somebody was in your house earlier today
20:25 Tom_itx pecking on your rue_bed pc
20:26 katsmeow-afk and they wouldn't talk to us
20:27 Tom_itx it's my opinion they spoke kat's language too
20:28 katsmeow-afk maybe rue went to McD's
20:29 Tom_itx maybe the intruder got him
20:29 katsmeow-afk possibly, cause he has no guard rails around the rue_bed
20:34 tsmeow-afk gnaws on a hunk of dead
20:53 rue_house I got there, the button pad they spilled juice into is acting up again, the register pops perfectly when they do it manually, told them to get a new button pad and stop calling me
20:54 rue_house the trace thats 90% red line (top layer) is 5V
20:54 Tom_itx did they pay you in burgers n fries?
20:55 rue_house no they get to pay in doubletime
20:55 Tom_itx double whopper with double cheese?
20:55 rue_house I dont do money, I just do work
20:55 rue_house dont ask me what it costs and dont try to pay me
20:55 rue_house I just do work
20:56 katsmeow-afk but you don't replace defective buttons?
20:56 rue_house katsmeow-afk, yes I still have some tweeking
20:56 Tom_itx just rinse them off in the frier
20:56 rue_house I dont fix electronics stuff for work :)
20:56 katsmeow-afk the problem with the 5v is same as yesterday, it's not apparent
20:57 rue_house nothing on this board is
20:57 rue_house I put more smt parts under thruhole parts too
20:57 katsmeow-afk so what is the 5v's problem?
20:58 rue_house its here there and everywhere, and its route dosn't fit one layer
20:58 katsmeow-afk ah
20:58 katsmeow-afk i don't even see where it's coming onto the pcb
20:59 rue_house the path to the 7xxx regulators is being a pain too
20:59 rue_house the 4 pin at the top
20:59 katsmeow-afk the red line does not goto the molex
20:59 rue_house the yellow line indicates it should
21:00 katsmeow-afk the yellow line under the relay?
21:00 rue_house y
21:00 rue_house yellow is unrouted paths
21:01 rue_house I think if I swap the order....
21:01 rue_house of...
21:01 katsmeow-afk push the molex to the right to get some room
21:01 katsmeow-afk then ,,,, what's pin 1 and 4?
21:01 katsmeow-afk i mean,, which pin is pin 1
21:01 Tom_itx that looks different than the last one i saw
21:01 rue_house from left to right
21:02 rue_house +24, +5, gnd, -24
21:02 rue_house I think I'm gonna change it to
21:02 katsmeow-afk ok, push it to the right, flip it over, the 5v will drop to the bottom going to the 8-pin headers
21:03 rue_house +24 -24 +5 gnd
21:03 e_house squ
21:03 katsmeow-afk i have no problem with the +5 beng on top, saves it shorting to gnd when you lay it down
21:04 katsmeow-afk unless you need a singleside pcb
21:05 rue_house I can only go thru the baord with thruhole components that have exposed leads
21:05 tsmeow-afk waits on rue to change it all up so no comments made now ma
21:05 rue_house I'm gonna try shuffling the pinout of the power connected
21:06 katsmeow-afk i'd lay out the pcb, then apply pin power as the pcb is laid out, not lay out the pcb to the powerpins, unless you have a standard pwer cable you cannot change
21:18 zhanx anyone alive yet
21:18 rue_house no, go back to sleep
21:18 zhanx k
21:18 katsmeow-afk <cough>
21:18 zhanx i will go back to hacking my windows
21:18 rue_house I think I'm trying to squeeze this pcb too much
21:18 zhanx with polymorph
21:19 katsmeow-afk trying to make the glass fit the window?
21:20 zhanx screwless plant holder since everything cost so much i am growing my own now
21:20 katsmeow-afk oh
21:20 zhanx conduit and wingnuts
21:21 tsmeow-afk tends to use a lot of 1" angle for everyt
21:21 zhanx dont have that so using what is free etc
21:21 zhanx its a sub 5$ project
21:21 zhanx polymorph is leftovers
21:22 tsmeow-afk
21:22 e_house grumbles about the 5V t
21:22 zhanx rest is construction site salvage
21:22 katsmeow-afk rue, just hand it to eagle
21:23 rue_house no, it would make a 4 layer unproducable board
21:23 zhanx so use via's
21:23 rue_house I am, I have to stay .1" away with traces
21:23 zhanx ok
21:23 zhanx use two boards
21:24 zhanx connector planes
21:24 rue_house hahha
21:24 rue_house stacked 2 layer boards with smt parts in the middle
21:24 katsmeow-afk sammich
21:24 zhanx would work
21:24 rue_house hell, have to use the long leads on the thruhole parts for SOMETHING
21:25 zhanx i wants a sammich
21:25 katsmeow-afk i used long wirewrap sockets to layer pcbs
21:25 rue_house and I want cookies
21:25 zhanx cookies
21:25 zhanx i got cookes
21:25 zhanx no sammich
21:25 zhanx monday i get real internets
21:26 e_house tries to work out how to solve the problem with a daughterb
21:26 zhanx or two
21:27 rue_house did you see?
21:27 zhanx nope
21:27 rue_house http://eds.dyndns.org/~ircjunk/circuits/olpcb.png
21:27 rue_house overload pcb
21:27 rue_house so no one driver ever tries to eat the entire 18A
21:28 zhanx k
21:28 zhanx i see 3 or 4 daughter cards
21:29 rue_house did you do any overload protection on .....damn
21:29 rue_house skippy? no
21:29 zhanx nope
21:29 rue_house larry? no
21:29 zhanx elf
21:29 rue_house elf!
21:29 rue_house hmm k
21:30 rue_house having a dual rail motor supply makes it more fun
21:30 zhanx no i never got around to it. still didn't in the the 2.0 either
21:30 rue_house I can suggest schematics if your interested later
21:30 zhanx 2.5? s the plan for fault torlerance later
21:30 zhanx is*
21:30 rue_house each leg has a 2A capable current sense and a 1A breaker
21:31 rue_house software resettable, trippable, and monitorable
21:31 katsmeow-afk toggle LM350's on and off for variable voltage plus current limiting
21:31 zhanx gonna need 6a breaker and a 8a current i think
21:31 zhanx its gonna jump remember?
21:31 rue_house I'm breakering by leg, so any one axis going over 1A will trip out the leg
21:31 katsmeow-afk and huge current pulses
21:32 rue_house I'm expecting a cascade failure at some point
21:32 rue_house buddy just lumbers
21:32 zhanx first grass
21:32 rue_house lm350...
21:32 rue_house wait, what is the lm350
21:32 zhanx thats wet
21:32 rue_house itns't it a t0-3
21:32 zhanx see kat was right again
21:33 katsmeow-afk you can get to-220 lm350's to
21:33 rue_house kats almst always right, cept when she gets too depressed :)
21:33 zhanx i am thinking npn/pnp setup skip the chip
21:34 zhanx been playing with it
21:34 katsmeow-afk any variable version of the 7xxx regulators, you can control the gnd ref pin to toggle on/off, and they self-protect and current limit themselves
21:34 rue_house yes
21:34 rue_house I wanted locking overcurrents
21:34 rue_house with 'no' voltage drop
21:35 katsmeow-afk toggle a switcher then
21:35 zhanx i need bigger motors to test my setup so i am looking for washer motors local
21:35 tsmeow-afk looks for more fish to gna
21:35 katsmeow-afk "washer motors" ?
21:36 zhanx yep
21:36 zhanx instead of ac i am gonna run them dc
21:36 rue_house 3/4hp
21:36 rue_house as servomotors?
21:36 katsmeow-afk you need zero intertia, not heavier motors, which is why i still recommend lightweight no-iron-rotor motors
21:36 rue_house 90* phase angle, fixed current?
21:36 zhanx 3/4hp
21:37 zhanx kat i cant afford them
21:37 zhanx unless i make them
21:37 katsmeow-afk or, windshield wiper motors, and overcurrent the hell outa them for jumps
21:37 rue_house uh eagle is randomly deleting traces on me
21:37 zhanx true
21:37 katsmeow-afk they might take 100amps for fractional seconds
21:37 zhanx gonna gear/spring load them etc..
21:38 zhanx i got a ton of free springs to play with now
21:38 katsmeow-afk junked trampolines?
21:38 katsmeow-afk ;-)
21:38 zhanx 4 of them
21:38 zhanx craigslist
21:38 tsmeow-afk shows zhanx her 5 gallon buckets of
21:38 zhanx darn
21:39 zhanx brb
21:39 katsmeow-afk salvage engine valve strings too, typical for a V8 is 75-90lbs compression in only 1/4 inch of travel
21:39 zhanx have to show the on call heater guy how to fix the heat
21:39 katsmeow-afk locomotive valve strings are much longer than car engine springs
21:40 tsmeow-afk has only 1/2 a 5 gallon bucket of valve spr
21:40 e_house offers kat a high-5 0.1"
21:40 katsmeow-afk WOOOOOOOOOOOO!!!!
21:40 tsmeow-afk looks puz
21:41 rue_house thats over 2"^2 shaved off
21:41 rue_house that would be like $16 if I were paying to get these made
21:41 tsmeow-afk
21:41 rue_house there's another .05"
21:41 rue_house tahts another 1"^2
21:42 katsmeow-afk i could often pack 2.3 chips per sq inch , before soic were invented
21:44 zhanx and his multi was set to VAC vs VDC wtf
21:45 katsmeow-afk you have dc power in your apt?
21:45 zhanx on the furnance yes
21:46 tsmeow-afk never heard of
21:46 zhanx control circuit is
21:46 katsmeow-afk ah, ok
21:46 zhanx its 12v
21:46 zhanx vdc
21:47 zhanx test your temp stat wites etc
21:47 katsmeow-afk many many controls still use the olde ac system, soa diy'er can install new controls on old equipment
21:47 zhanx this is a newish one etc
21:47 tsmeow-afk
21:48 zhanx i might have to show him how to bypass the limits to get heat tonight if it hits 60 in here
21:49 katsmeow-afk i often turn heat off at nite, let it drift down to 72-ish
21:49 katsmeow-afk R50 insulation, yanno
21:49 zhanx at 63 right now
21:49 katsmeow-afk but i am heating only one room atm, having not gotten moved back in here yet
21:49 katsmeow-afk prolly 63 in *this* room, unheated
21:49 zhanx i am renting a farm house
21:49 zhanx old
21:50 katsmeow-afk been there, done that
21:50 katsmeow-afk my condolences
21:50 zhanx r0
21:50 zhanx and winter came back etc
21:50 rue_house aha
21:50 rue_house by swapping the pins of the relay coil...
21:51 katsmeow-afk by swapping the pins of the relay coil... we apply power backwards across the internal spike diode....
21:52 rue_house nono just the coil
21:52 rue_house then I swap the ...
21:52 rue_house swap the switches of the realy and the +24 -24V pins
21:52 Tom_itx 72ish?
21:53 Tom_itx mmm
21:53 katsmeow-afk i have found so many ways to make this cpu design run several instructions at once, but i cannot break the time of 12ns for math and logic ops, and i am aiming for 10ns
21:53 rue_house ooooooo
21:54 rue_house I think that did it
21:54 katsmeow-afk i can get it down to 7.5ns if i use dram and a lookup table, but dram is like wait-before-use because of the refresh
21:55 katsmeow-afk and i haveto CAS and RAS it too
21:55 Tom_itx rue_house, what are you gonna do with those boards i sent?
21:55 Tom_itx i'm trying to figure what to do with these
21:55 katsmeow-afk why did you make them?
21:55 Tom_itx i had the parts
21:56 Tom_itx http://tom-itx.dyndns.org:81/~webpage/boards/atmega32u4/atmega32u4_1.jpg
21:56 zhanx ok back
21:56 Tom_itx i got 3 like that and one quite similar
21:57 zhanx show the pro how to fix it
21:57 zhanx thank god i had a 12v relay
21:58 rue_house http://eds.dyndns.org/~ircjunk/circuits/olpcb.png
21:59 rue_house :))
21:59 zhanx better
21:59 rue_house it'll pack now too
21:59 zhanx ok house is warming up again
21:59 katsmeow-afk looks smaller
21:59 rue_house 'cept for that top right bit
22:00 rue_house maybe I'll put a smily face there
22:00 rue_house cause the world needs more smiley faces
22:00 zhanx http://www.youtube.com/watch?v=ghrDIQ-K8mg&feature=share
22:01 katsmeow-afk holy crap, i seen those humans in a local walmart
22:02 zhanx lol
22:02 rue_house ickgh
22:03 katsmeow-afk aweful lot of crossdressers in that video
22:08 rue_house how to meausre some elses internet speed
22:09 rue_house give them a video link... see how long it takes for them to comment on the ending
22:09 e_house giggles all the parts to see if the board will get any sma
22:11 katsmeow-afk turn those 3 dip-8 headers sideways so they will settle to the bottom of the board
22:12 rue_house if I do that I cant route them
22:12 rue_house its really hard
22:12 tsmeow-afk
22:13 rue_house their wired so they can be plugged in backwards, reversable
22:13 katsmeow-afk you're at that point now where you need to squash the space of (the relay and the molex) out of the other parts space, to shrink it usefully smaller, unless you can put two such circuits on one pcb, sharing the molex
22:14 rue_house but it seems as vertically crunched as it wants to get, I swear it can get narrower
22:14 katsmeow-afk if you can put two one one pcb and share the molex, you can save more space
22:14 rue_house the size of the smt
22:15 katsmeow-afk take the pcb, turn it 180, and set it down so the molex line up on the pic on my screen
22:15 rue_house the size of the thruhole parts is backing me up, on the real one I think I can trim a bit more off just cause I can make resistors .1" .2" .3" or anything else I want
22:16 rue_house ?
22:16 Tom_itx rue_house
22:16 rue_house yea
22:16 Tom_itx is it good to have the real kat back?
22:16 rue_house yes
22:16 tsmeow-afk looks embarra
22:17 m_itx hugs katsmeow
22:17 e_house turns off all the silkscreen to see just the tr
22:17 zhanx yea its good i must admit it
22:19 katsmeow-afk if you turn the dip-14 sideways, yo can clear up .3" under the molex, but it doesn't helpunless you also turn those headers and clear space under the relay too
22:20 katsmeow-afk you could relocate those diodes under the pcb, and bunch the dip-8 chips together
22:20 rue_house there is a lot of little gaps everywhere
22:20 rue_house ignoring the top right
22:20 katsmeow-afk yeas
22:20 rue_house o0h right, I was gonna put a connector on for the avr too
22:20 rue_house then I dont need to have it jigged into the main bus
22:21 Tom_itx oh rue_house
22:21 Tom_itx what ver debian are you running?
22:21 rue_house how many miles between rotor/cap changes?
22:21 rue_house hahah
22:21 Tom_itx i downloaded 6.0.4 the other day
22:22 Tom_itx wonder how much has changed in it
22:22 rue_house I installed this system back in 1998 or 2001
22:22 rue_house I'v only done upgrades since
22:22 rue_house and not many
22:22 Tom_itx well, i wanted to reinstall my web pc and set it up as a router while i'm doing it
22:22 Tom_itx is that asking for trouble?
22:22 Tom_itx so i figured i'd get the lastest iso
22:22 rue_house I was bitten by a few upgrades, decided to only do them as needed
22:23 zhanx ok nght all
22:23 Tom_itx there's alot of stuff on it that i probably won't reinstall
22:23 Tom_itx like the temp sensor stuff
22:23 rue_house gnight
22:23 katsmeow-afk rotor/cap changesdepends tons on the dirt in the air and the amount of high voltage from the coil
22:23 Tom_itx would the pc work good as a router for a few pc's?
22:23 Tom_itx i wanna get a wireless access point to use on it as well
22:23 katsmeow-afk or, how much your radiator leaks and keeps it wet with antifreeze
22:24 rue_house can having the wrong plug cables cause a rotor to die early?
22:24 katsmeow-afk not nowadays, they are all resistor wire now
22:25 rue_house see last I checked, the rotor was fine, so I'm confused why is 'suddenly' went
22:25 katsmeow-afk usetobe, yeas, when you could choose solid wire vs resistor wire plug lines
22:25 katsmeow-afk when you checked, did you change anything?
22:26 Tom_itx rue_house, do you know much about these types of devices? http://www.caymanwireless.com/product.php?id_product=171691
22:26 rue_house the plugs were changed after
22:26 rue_house and I didn't gap them from new
22:26 Tom_itx you think that would work under the server/router ok?
22:26 katsmeow-afk ah, then the current or voltage at the rotor terminal certainly changed
22:27 rue_house wstf is that?
22:27 rue_house if its a wireless bridge, then yea
22:27 Tom_itx wireless access point
22:27 katsmeow-afk ?
22:27 rue_house so its a bridge
22:27 Tom_itx yeah
22:28 Tom_itx i figuerd that may work better than an off the shelf wireless router
22:28 rue_house meh
22:28 Tom_itx is it hard to add pc's if you use linux for a router?
22:28 rue_house all wireless is &**(&^&^^%%^^^(((((((((((((((((((
22:28 Tom_itx i know
22:28 Tom_itx but i have a need for it here
22:28 rue_house no
22:28 katsmeow-afk Tom, if you can write code to bind to the hardware lan and the wireless, and then handle the going's on tween them
22:28 rue_house linux works with everything
22:29 Tom_itx but with my linux skills?
22:29 rue_house what are you trying to do?
22:29 katsmeow-afk you will find winxp will not re-establish a dropped secure wireless connection on it's own
22:29 Tom_itx replace my router with the pc
22:29 rue_house just have wireless on the network?
22:29 Tom_itx no, it'll have a 24port switch on it and one of those on the switch
22:29 rue_house yea, base install of debian with nothing, and install shorewall
22:30 Tom_itx what's shorewall?
22:30 rue_house add a dhcp and bind server
22:30 rue_house its firewall software
22:30 rue_house make sure your internet and lan are different physical ports
22:30 Tom_itx it's got 2 lan cards, is that all i need?
22:30 rue_house yes
22:30 rue_house there is prolly a gui to do it
22:30 Tom_itx then run the switch off one of them
22:30 rue_house I cant help there
22:31 rue_house off your lan side, yea
22:31 Tom_itx ok, if i decide to install the gui how do i get the non gui if i want it?
22:31 Tom_itx terminal?
22:31 Tom_itx i probably won't
22:31 Tom_itx just asking
22:32 Tom_itx would the GUI have stuff to manage the dhcp etc on the server?
22:33 Tom_itx it's kinda moot as i don't have a keyboard or monitor on that pc anyway
22:33 katsmeow-afk how do you know it's moot if you cannot see it?
22:34 katsmeow-afk i'd put on a monitor just to know if it bsod'd
22:35 Tom_itx it would be obvious
22:35 Tom_itx nothing would be working :)
22:36 katsmeow-afk but could be not working from a chewed up cable, while the puter is fine
22:36 Tom_itx i generally work on it thru putty
22:36 Tom_itx have been since my site has been up
22:36 Tom_itx that and winscp
22:37 Tom_itx i just didn't know if i would need more access to it since it would be a dhcp server
22:37 Tom_itx to manage the firewall stuff etc
22:37 tsmeow-afk
22:55 katsmeow-afk RustySpigot.com
22:55 katsmeow-afk simple solutions for complex problems
22:55 katsmeow-afk Page Not Found
22:55 katsmeow-afk wow, that was a simple solution , vs fetching the page and sending it to me :-/
22:56 rue_house oooo yea
22:56 rue_house I can get rid of two of the diode because the comparitor outputs are open collector
22:56 katsmeow-afk ok
22:56 katsmeow-afk how about using smaller trimppots?
22:57 katsmeow-afk or, laying out for a resistor, trimming the circuit, then replacing the pot with a fixed resistor?
23:01 Tom_itx how well does linux adapt to new hardware if you swap hdd to another pc?
23:02 theBear just fine
23:02 theBear no questions asked.. on a 'modern' setup you can even randomly swap which connector is which drive and it will still boot/work without complaint :)
23:02 Tom_itx the lan cards may map differently
23:02 theBear they should be remembered by udev
23:03 Tom_itx by the mac address?
23:03 theBear oh, you mean moving the system drive... yeah, on a modern system yer lan cards and things will be one higher unless you manually or prior-specifically said not to remember
23:03 theBear umm... lemme check
23:04 theBear yeah, mac address pre-filtered by being a net-card 'device'
23:04 Tom_itx i'll mirror a drive and try it i guess
23:04 theBear so same net card should be 'magic'
23:04 Tom_itx one of the lan is on the mb though
23:04 Tom_itx so one would be different
23:04 theBear linux doesn't do any stupid auto-reconfig-to-important-stuff like windows, you can't "hurt" it trying to boot an original drive on another machine
23:04 theBear Tom_itx, it should still see the 'known' address and number that same as before
23:05 Tom_itx k
23:05 theBear so mobo will become 2nd device
23:05 theBear or 3rd, whatever
23:05 Tom_itx well it's sleep thirty here
23:05 Tom_itx i may tackle it tomorrow
23:05 theBear mmk, i should be around to help... i've booted more weird crap than anyone
23:09 rue_house damnit I need supper
23:11 rue_house katsmeow-afk, ?
23:12 katsmeow-afk Tom, i shut the heat off in the other room 7 hrs ago, the temp has gone UP to 75F, it's 48F outside atm
23:12 katsmeow-afk yeas rue?
23:12 rue_house http://eds.dyndns.org/~ircjunk/circuits/olsch.png
23:13 rue_house thats the resulting schematic after the mods to route it on the baord
23:13 rue_house thoughts?
23:13 katsmeow-afk why two resistors like R5, r9?
23:14 rue_house 800R
23:14 rue_house 680+120
23:14 katsmeow-afk why does ie have such a crappy img rendering?
23:14 rue_house zoom 1:1
23:14 katsmeow-afk i think that accuracy in resistors isn't necessary, as you have those diodes which will be very temperature sensetive
23:15 rue_house :) yes, but it feels more correct
23:15 rue_house the gain isn't out by much from the test circuit I did
23:15 katsmeow-afk zoom 1:1 puts it sooooooo far off the page i cannot see anything
23:15 tsmeow-afk switches t
23:15 rue_house I'll re-render smaller
23:16 katsmeow-afk nono, don't lose details
23:16 theBear what is that ? zero cross detector or something ?
23:16 theBear hang on, 555 ? wtf rue ?
23:16 rue_house re-rendered
23:16 katsmeow-afk arg, ff isn't any better on this one
23:16 rue_house theBear, the 555 is an RS latch with a relay driver built in
23:16 rue_house :)
23:16 theBear looks fine here in ff if i real-size unzoom it
23:17 theBear rue_house, ok, even so, wtf plugs into the left side ?
23:17 rue_house it has a output for hte computer to know its tripped, a reset to reset it, and a driver to operate the relay
23:17 rue_house its PERFECT
23:17 theBear hmm... overcurrent ?
23:17 rue_house those are the connectors to the driver baords
23:17 rue_house yes
23:17 theBear hmm.. no shunts eh ? sensitive
23:17 rue_house .01R
23:18 theBear what kinda wire ?
23:18 rue_house pardon me, I didn't put in any values
23:18 theBear pfft, values are for amateurs
23:18 rue_house their 1% current senses
23:19 rue_house because the drivers are split supply, the current detect is bipolar
23:19 rue_house 0A is 2.5V and it goes from 0 to 5V for +2A -> -2A
23:19 theBear nice
23:19 rue_house (yea its inverted)
23:19 rue_house the two trims allow for setting the + and - overload currents
23:20 rue_house I thought it was halarous that a 555 fit the bill
23:20 katsmeow-afk for each resistor network on the '074's, why are there two pins on the dip-8 headers?
23:21 rue_house their both grounds
23:21 rue_house the motor ground goes thru the sense resistor to detect current level
23:22 katsmeow-afk so R7 is a current sense?
23:22 rue_house 7/13/16
23:22 rue_house .01R
23:22 katsmeow-afk so you use 2 pins for redundancy / lower resistance?
23:22 rue_house you can reverse the connectors
23:22 rue_house it was a stupid idea I'm now in legacy support of
23:23 katsmeow-afk umm, but the reversing header option makes for a bigegr pcb and more difficult routing
23:23 rue_house it does indeed
23:23 katsmeow-afk ok
23:23 rue_house and, it dosn't really shed much idiotproofing as jester found out when he plugged one in offset by 1 pin
23:23 katsmeow-afk use smaller faster diodes, 1N4004 are dead slow
23:24 rue_house yea, eagle dosn't have 1n914
23:24 katsmeow-afk try 1N4148, and there's a UF4004 if you need that exact form factor
23:25 rue_house I think I put 914 and 4148 int eh same drawr :)
23:25 rue_house are the 4148 not the blue ones?
23:25 katsmeow-afk almost any transistor BE junction is faster than a 1N4004
23:25 rue_house :)
23:26 katsmeow-afk UF5401 smt on ebay was super cheap at one time
23:26 katsmeow-afk and they are 50ns fast
23:26 rue_house the most major thing I know I left out was tieing the inputs of the unused op-amp
23:26 rue_house katsmeow-afk, I'll peel un-identified smt diodes off motherboards as req'd :)
23:27 katsmeow-afk woah, they aren't smt or cheap now
23:27 katsmeow-afk 50PCS,Diode SMD SMT LL4148 1N4148
23:27 katsmeow-afk 99 cents, free s&h
23:27 rue_house the advantage with the reversable connectors is that, if your carefull, you can use single row jumper cables and chain the wiring
23:28 katsmeow-afk $3 : 20� 74F1056 OCTAL SCHOTTKY DIODE ARRAY SOIC-16 SMD/SMT
23:28 rue_house huh
23:29 katsmeow-afk just saying, 1N4004 are soooo 1960's
23:29 katsmeow-afk as proof, i have some
23:30 katsmeow-afk but i have so many parts from the free cable box mobo, it's amazing
23:33 katsmeow-afk <cough>
23:33 katsmeow-afk !ping
23:35 katsmeow-afk where'd everyone go?
