00:03 katsmeow my brain is shutting down a few minutes early, i can feel it
00:07 katsmeow you aren't bidding on a gyro , are you?
00:14 rue_house whats 30Mhz /4096?
00:14 rue_house not me no
00:14 rue_house I have about 30 of them from some game controllers I bought for a steal
00:14 katsmeow grrrr
00:14 rue_house 7.3Khz
00:14 katsmeow you going to use them?
00:14 rue_house so far I cant talk to them
00:15 rue_house they are blobs, I'm guessing on the part number
00:15 katsmeow oh
00:15 katsmeow i need a part number to offer you $3 for them
00:15 rue_house the TLC5940 takes in the clock for hte pwm, so you can use whatever pwm freq yo uwant
00:15 rue_house up to 7.3Khz
00:16 rue_house katsmeow, I'm not eve sure what they are, you sure you want one?
00:16 katsmeow no, that's why i said : i need a part number to offer you $3 for them
00:16 rue_house how the hell did 10:00 slip up on me
00:16 katsmeow it slipped PAST you
00:16 rue_house if you want one I can send it to you
00:16 katsmeow no, i need to know what it is, else i cannot use it
00:17 katsmeow no seenceses wasting postage
00:17 rue_house I wasn't able to find out for sure, my best guess is on a hard drive that had a head crash
00:18 rue_house (the things you dont know you lost till your looking for them)
00:18 katsmeow right, multiply that x 30 to know i i feel without a good backup program
00:19 katsmeow takes a week to backup a 320gig drive over the lan, winblows keeps droppingt he lan connection
00:20 katsmeow ok, i got a ADXL345 on breakout bd for $2.75 ,, humans put in **7** bids to get even that high
00:20 rue_house yea, the sellers have buddy sellers they use to jack up prices for them
00:20 rue_house thts why you want buy-it-now
00:21 rue_house ok I'm buying $12 in chips for the mecha
00:21 katsmeow wow!
00:21 rue_house thats 12/120ths of the budget
00:21 rue_house but it'd save me ...
00:22 katsmeow the cheapest buy-now is $3.09, so i saved 86 cents
00:22 rue_house hmm, whats it save me, I was gonna have an 8051 use parallel io to operate the solinoids directly
00:22 rue_house oh you won, good show
00:23 katsmeow i said i got it
00:23 rue_house I thought you meant you got a bid on it, sorry
00:24 katsmeow i figure i use those 4414 to poll the adc and drive 8 7-seg each, what do i need 30Mhz serial ports for?
00:24 rue_house I'm talking for me
00:25 rue_house the 12 bit pwms run at up to 30Mhz count speed
00:25 katsmeow i can use 2 ports to drive and mux the 7-segs, one to poll the adc's, and one for com to a external serial buss for remote monitoring, i don't need no steeeking 30Mhz serial port
00:26 rue_house do you still want my help with code?
00:26 katsmeow it's after midnite again, not tonite dear
00:27 rue_house whenever
00:27 rue_house I meant in general with the project tho
00:27 katsmeow ADXL345 3-Axis Digital Acceleration of Gravity Tilt Module for Arduino
00:27 katsmeow Time left: 2h
00:27 katsmeow
00:27 katsmeow $2.62
00:27 katsmeow Free shipping
00:28 katsmeow in case you are interested in knowing the mecha is tipping over
00:28 rue_house there will be a gyro that tips the pilot with the mecha
00:29 tsmeow ponders ultrasonic distance meter buried in the palm of the hand,, or tween a couple fin
00:33 katsmeow why would you put a ITG3205 and a ADXL345 on one pcb?
00:36 rue_house haha, someone I knw just found a CRS robot at an auction, gonna put a bid on it see if I get it
00:37 rue_house katsmeow, I have a way of making a 'down' sensor that works really well, thanks
00:37 katsmeow umm, ok, didn't think of a 'down' sensor
00:38 katsmeow the ITG3205 and ADXL345 are both gyros, i wonder why someone would put both on one pcb
00:38 rue_house I dunno
00:38 rue_house I saw one with 3 sensors on it
00:38 rue_house !??!?!!
00:39 katsmeow HMC5883L is a magnetic compass
00:41 katsmeow i wonder why LM34 cost more than LM35
00:48 katsmeow It includes the ADXL345 accelerometer, the HMC5883L magnetometer, and the ITG-3205 gyro.
00:48 rue_house lm75 rules
00:48 rue_house lm35 is analog
00:49 rue_house iirc, the TCN75 (microchips version) is much cheaper than the lm75
00:50 katsmeow 5 for $15 ?? ouch
00:50 katsmeow LM75 is much cheaper than TCN75 on ebay
00:52 rue_house huh
00:52 katsmeow i dunno, it's a battery charger, i can prolly shut it off for 1 millisec and read the pass transistor base-emitter resistance, and the battery won't care
00:52 katsmeow or, since there's two transistors on the heatsink, measure the one that's not on
00:53 rue_house http://www.digikey.ca/product-detail/en/TCN75AVOA/TCN75AVOA-ND/735993
00:53 rue_house the soic is still big enough to solder
00:53 rue_house :)
00:54 katsmeow that's why, it's too obvious, the accel chip won't measure dc movement, it's an ac movement detector, while the real gyro will keep putting out a signal while it's moving, even if not accelerating
00:54 rue_house ah
00:55 rue_house back to integrals and derivitives
00:55 katsmeow <cough>
00:55 rue_house ?
00:55 rue_house you see I posted te dk link yes?
00:55 katsmeow yeas sir
00:57 rue_house see much cheaper than $5 ea eh?
00:57 tsmeow nods slowly as she just saw she's on the canadia
00:57 rue_house I'd expect to see them for 0.25 on ebay if they are ~$1 on dk
00:58 rue_house dollar is almost 1:1
00:58 katsmeow stock and s&h may be diff
00:58 rue_house dk is $8 delivered
00:59 katsmeow i wanted to check the tiny2313 and tiny85 bookmarks too, cause of the poweroutage
00:59 katsmeow you see what the neighbors pulled today?
00:59 rue_house no...
00:59 katsmeow [16:30] <katsmeow> goddamned neghbors called to say their power was too high and was always shutting off, so the power co came out ans hut off MY power
00:59 katsmeow [16:30] <katsmeow> they LIED to the powerco, and got MY power disconnected
00:59 katsmeow [16:30] <katsmeow> goddamned humans
00:59 rue_house I didn't read back today
00:59 rue_house WTF!!!
01:00 rue_house they reconnected, yes?
01:00 katsmeow i am telling you, it's WIERD out here
01:00 katsmeow yeas
01:00 katsmeow i went up there, they had my power transformer unhokked and all
01:00 katsmeow unhooked
01:00 rue_house why are your two palces mixed up so often
01:00 rue_house you have your address in huge letters on the gate
01:00 katsmeow there was no need to mix up, we are on different poles, different pigs
01:00 rue_house maybe you should put your neighbours address on your gate
01:02 katsmeow maybe i should be working my ass off on ANYTHING that floats instead of a nice boat
01:04 rue_house sometimes not being pickey gets things done
01:04 rue_house I'v come to that conclusion on my projects
01:04 rue_house sacrifice perfection for completion, then fix it up later
01:04 katsmeow yeas, problem is the trimaran amas are too narrow to live in, and the center hull is a sizeable boat
01:05 katsmeow if i join just the amas to make a catamaran, it will be just a barge, no cabin space to live in
01:06 rue_house can you find a crazy government auction on a 120' steel ship?
01:06 rue_house $50 or what haveyou?
01:06 rue_house it happens you know
01:06 katsmeow no, but i know of one floating around theAtl with no one on it
01:07 rue_house not the condom island!?
01:07 katsmeow no
01:07 rue_house oh good
01:08 katsmeow http://www.vesseltracker.com/en/Ships/Lyubov-Orlova-7391434.html
01:08 katsmeow 220m long
01:09 katsmeow there's no one on it, it's been adrift for amonth
01:09 katsmeow even a wikipedia page on it now
01:10 rue_house well, go get it?
01:11 rue_house 220m is a bit of a rig to maintain tho
01:11 rue_house maybe it has some good sized sub-ships on it
01:11 rue_house dont the huge ones carry a few tugs?
01:12 katsmeow no
01:12 katsmeow and no i cannot afford fuel for it
01:12 katsmeow but, if i bring the boat to shore, i can charge salvage on it, or keep it, but atm, i cannot get to it
01:13 katsmeow there's 1 or 2 boats in that condition every yr, that's the 2nd boat this yr, the other was a fishing boat off Japan (not counting the one sunk off western Canadia)
01:13 rue_house I dont think even you and thebear togethor can row in a 220m ship
01:14 katsmeow well, if it was in the Atl gyre, it would prolly float around there for decades with no fuel
01:14 katsmeow getting it there would cost
01:22 tsmeow wanders off to
01:22 katsmeow-afk gnites
01:22 rue_house gnght
04:43 katsmeow-afk TROPICAL Cyclone Rusty is now battering WA's Pilbara coast after being upgraded to a category four storm.
04:43 katsmeow-afk A red alert has been issued for people in Pilbara region towns between Pardoo and Whim Creek, including Port Hedland and South Hedland.
04:43 katsmeow-afk These residents are being told to go to shelter immediately.
04:43 katsmeow-afk The slow-moving monster storm was still over the sea this morning but the Bureau of Meteorology (BoM) says it's likely to cross the northwest corner of WA later in the day.
04:43 katsmeow-afk "Wind gusts to 120 kilometres per hour have already been experienced in Port Hedland and conditions there are likely to get slowly worse during the day," the bureau said.
04:44 katsmeow-afk The slow-travelling cyclone barely moved overnight but wind gusts have strengthened to 230km/h near its centre.
04:44 katsmeow-afk Destructive wind gusts of more than 165km/h are predicted in the area as the cyclone approaches the coast.
04:45 katsmeow-afk The deputy mayor of Port Hedland shire, George Daccache, a resident of 40 years, expects the cyclone to be one of the worst the town has seen.
04:46 katsmeow-afk course, that's the other side of the continent from Riff
09:07 rue_house hmm
09:07 rue_house thebear is on the other side from rif
18:50 tsmeow-afk walks around Riff till she gets to the other side where bea
18:53 tsmeow-afk keeps wal
18:54 katsmeow-afk no bear on this side
18:54 tsmeow-afk keeps wal
18:55 tsmeow-afk walks under a cow, but finds no bear on this side either, and keeps wal
18:55 katsmeow-afk no bear on this other side
18:55 tsmeow-afk keeps walking and is approaching a
18:56 tsmeow-afk walks under this cow and notes it looks a lot like the other cow a while
18:56 tsmeow-afk keeps wal
18:56 Tom_itx see forest gump yet?
18:56 katsmeow-afk no, but wasn't looking for him
18:57 tsmeow-afk keeps wal
18:58 tsmeow-afk arrives at a cow with a lot of cat pawprints under it, which is odd, but no bear on this side ei
18:58 tsmeow-afk notes all these cows look alike, and so do all the pawpr
18:59 tsmeow-afk is getting d
19:01 tsmeow-afk decided if she runs, she may get to the other side of Riff faster where the bea
19:02 tsmeow-afk notes these cows surrounding Riff are increasingly agitated, specially this 14th
19:04 katsmeow-afk maybe i am not going to get to the other side before dinner, and i should head back where i started
19:06 tsmeow-afk takes off back where she started, remembering she passed under 14 cows be

19:06 Tom_itx the spun part from my cnc coded mold
19:06 Tom_itx test part
19:08 katsmeow-afk who is the drunk holding a chamberpot over his face?
19:08 Tom_itx some brit
19:08 Tom_itx i dunno
19:08 katsmeow-afk who is any pugh?
19:08 Tom_itx some other brit making the part
19:08 Tom_itx he just needed the code i sent
19:09 katsmeow-afk i wonder if that crown part could be made in a mold with explosive water hammer
19:10 Tom_itx they're gonna reuse it
19:10 katsmeow-afk reuse it?
19:10 Tom_itx it's soldered on i guess
19:10 katsmeow-afk if they make a mold of it, they can make more and reuse them too
19:12 Tom_itx he's gonna try to finish it by saturday
19:13 katsmeow-afk make like a hollow copper globe to screw onto a pipe, fill pipe with water, insert dynomite, <BOOM> , water pressure expands the copper to be cold molded by the inside of the umm, reverse crown
19:14 Tom_itx where does the trapped air go?
19:14 katsmeow-afk at 10,000 psi, it doesn't matter
19:16 katsmeow-afk saw a procedure, they made a reverse 3D topo map , laid a copper plate over it, laid sand and then detcord over that, and then a real heavy steel plate, <BOOM> , the copper now looked like a 3D topo map, and they could make as many as they had detcord for
19:21 tsmeow-afk ponders a quieter method of making a 50,000+ psi water hammer pulse, by using a mechanical assist on a 5ton block of steel hitting a 1/4 inch dia hydraulic pump pi
19:38 rue_house mmm
19:39 rue_house I was thinking about a hydraulic former
19:39 rue_house how far do you think a person could get with a pressure washer?
19:39 Tom_itx not far enough
19:40 Tom_itx i've made blocks for hydropress before though
19:41 rue_house \HAHAHA!!! my article maDE IT!!
20:35 katsmeow-afk what did your article make?
20:35 Lola8088 http://hackaday.com/2013/02/27/interpreting-brainfk-on-an-avr/
20:38 tsmeow-afk doesn't understand the point of bra
20:49 rue_house katsmeow-afk, well, it fulfills RISC
20:55 Tom_itx what was the point of the exercise?
20:56 rue_house I had all the code, why not?
20:56 rue_house I was working with the avr eeprom and already had the interperter
20:56 Tom_itx doesn't look like a language i'd code in much
20:56 rue_house no
20:56 Tom_itx the eeprom routines worked ok then..
20:56 rue_house low instruction count is about its only asset
20:56 rue_house gclib
20:57 Tom_itx if you call morse code instructions :)
20:57 rue_house for the avrs eeprom
20:57 katsmeow-afk http://hackaday.com/2013/02/25/veronica-6502-computer-reaches-hello-world-stage/ <<== why does the computer keep printing out "O HELL" ??
20:57 Tom_itx gclib?
20:57 Tom_itx never heard of it
20:57 rue_house the external eeprom gets messy, you have to know exactly what eeprom your using
20:57 rue_house avr libc sorry
20:58 rue_house you cant just swap in/out any 24Cxx serial eeprom you want and use the same code on it
20:58 rue_house katsmeow-afk, hehe
21:03 katsmeow-afk skynet waking up and finding out it's in a 6502: OHELLOHELLOHELL
21:04 rue_house hahahah
21:04 rue_house http://www.ebay.ca/itm/360602497983?ssPageName=STRK:MEBIDX:IT&_trksid=p3984.m1426.l2649
21:05 rue_house cant enter less than $2.10
21:05 rue_house damn
21:06 katsmeow-afk wait, you haveto pay sales tax if you buy canadian money with canadian money?? That's a hell of a ripoff!
21:06 rue_house no
21:06 katsmeow-afk i bet no one asks for change for a dollar up there!
21:06 rue_house the next bid step is $2.10
21:06 katsmeow-afk Things to Know Before Bidding
21:06 Tom_itx just bid on the free shipping

21:07 rue_house never paid tax on anything from china
21:08 katsmeow-afk well, starting bid was 99 cents, so wait till 3am and have tobbor bid $1 on the next one
21:08 rue_house hah
21:09 Tom_itx i should bid on that
21:09 Tom_itx i like collecting coins
21:09 rue_house next step is $2.10
21:09 Tom_itx i've lost more than i kept though
21:11 Tom_itx i've got a mexican coin similar to those with the 2 tone metals
21:11 Tom_itx not worth much
21:13 rue_house I wonder if they add polymers to pencil lead to harden or soften it
21:13 katsmeow-afk to hold it together
21:14 rue_house so 4b lead has less polymer than 4H
21:15 katsmeow-afk i dunno, but i know a rod of pure carbon would keep breaking
21:15 rue_house gouging rod
21:17 katsmeow-afk that wold be a fat coppery pencil, i spose
21:17 rue_house !! I found another one there are NO carpender pencils on ebay!
21:18 rue_house ter, nevermind

21:19 rue_house how many of those to make a supercap sufficient to run my truck on with electricity?
21:22 katsmeow-afk this is wierd, i was wearing glasses, looking for scratch on another glasses, and discovered an image of the cfl which appeared to be on the glasses, not shining thru them
21:23 e_house checks the rendering engine in kats simul
21:23 katsmeow-afk there was an image for each eye, one pink, the other green, from the same cfl, and the thing is, the images were focused on the glass, not beyond it
21:23 katsmeow-afk i didn't focus on the light beyond to see the mages, i focused on the glass to see the image
21:24 katsmeow-afk wierd
21:25 katsmeow-afk ok, going back up to put in more lites

21:27 rue_house looks like they go about 50c ea
22:29 katsmeow-afk i can't even stop to take a sleepy pill without diverting to make something :-/
22:29 katsmeow-afk "never used" pencils? are you sure they work?
22:30 tsmeow-afk noted that even tho it looked dark upstairs with no lites installed, it *really* looks dark now when they are turned
22:34 katsmeow-afk a 14-copter : http://www.youtube.com/watch?v=dvcFB5V7fi4
23:03 katsmeow-afk how to use up $500 in copper : http://www.youtube.com/watch?v=tOpoupq7DRI
23:04 katsmeow-afk and then the moron insulates it with paint
23:06 katsmeow-afk The panels cost about $450 to $500 each to build
23:16 rue_house how long before a plane ran into one of them tho
23:16 rue_house or a storm blew one up
23:17 rue_house hmm
23:17 katsmeow-afk they tout them as power generators, which is BS, but it's a heck of a copter
23:18 rue_house I was going to so something like that till I looked at the price of the fittings
23:18 rue_house dont need copper anyhow
23:19 katsmeow-afk di it minus fittings, drill holes in headers, but it's still a huge copper cost, and heis using heavy thick-walled softdrawn as the verticals, he should look for some 1/4 thinwalled
23:20 katsmeow-afk i think i figured out how to make some for $20 per 2x8 all alum or galvanised
23:20 katsmeow-afk at that cost, the glass will cost more
23:20 rue_house gapped sheets are much better economically and etch
23:20 rue_house wow, all copper, thats overkill
23:21 rue_house only an hour to solder the sheet, wow
23:22 rue_house no backing insulation?
23:22 katsmeow-afk enourmous overkill, plus it's been found that only a few thou of anything over the metal can reduce heat transfer 50%, and he intentionally painted them
23:22 rue_house ah
23:22 rue_house black, yea
23:23 katsmeow-afk much better to anodise or stain , not paint
23:23 rue_house I made a panel from corriplast and it did ok
23:23 katsmeow-afk i can't help but think black water flowing under double glass would be best
23:25 rue_house copper and propane to make heat pipes
23:26 katsmeow-afk i'd hate to have a propane leak that you can't find for hours, and someone comes by smoking
23:29 rue_house I dont know how much they get loaded with
23:35 katsmeow-afk ideally, you'd run some thing cheap and benign like water in the solar collection field, and use it to heat a small amount of propane or whatever
23:35 katsmeow-afk ammonia, even
