00:09 GargantuaSauce http://www.youtube.com/watch?v=ayxz5GUonBE bad black metal videos are so damn funny
07:15 katsmeow-afk hmm, when the terrain tilts, the robot leans, the antenna shifts to one side, and tracking cause it to steer left by the same amount the antenna leaned to the right
11:05 rue_house alien gets job as tv studio prop maker, didn't understand that laser riffles weren't supposed to actually work.
11:11 katsmeow-afk the reason the robot in Lost In Space looks like that is he really is a set of stacked tesla coils, so he can shoot those sparks
11:11 rue_house :)
11:13 rue_house the outcome of a 'higher is better' volts marketing competition
11:15 tsmeow-afk decides to go for Screaming Fast chips as subsections, excessive power use be darned, and simply shut off power to them during the 95% of the time they are not in use (2N7000 swi
11:15 katsmeow-afk saves up power for throwing those sparks
11:47 rue_shop3 ok, what size is most likley for a shaft thats .310"
11:47 rue_shop3 (real size)
11:48 katsmeow-afk 7.874 mm
11:49 rue_shop3 no in real imperial
11:49 rue_shop3 x/y
11:49 rue_shop3 where x and y are integers, and y is 16 or smaller
11:51 katsmeow-afk 5/16 .3125
11:51 rue_shop3 hah, you did it before I wrote a program to do it for me!
11:51 rue_shop3 thanks kat :)
11:52 katsmeow-afk note it's .0025 over, so sneak up on it
11:52 rue_shop3 the shaft may be +-
11:53 rue_shop3 and I have limited trust on the calipers
11:53 katsmeow-afk k
11:53 rue_shop3 that said, the rillbit reads at .314
11:54 rue_shop3 a drill bit so dull...
11:54 katsmeow-afk sand down it's diameter a lil?
11:54 rue_shop3 prolly drill faster with a butterknife
11:54 rue_shop3 I have a number set too
11:55 katsmeow-afk that's why i said to sneak up on it (with a smaller bit first, then the real size or a reamer)
11:55 rue_shop3 the shaft varries from .316 to .312
11:56 katsmeow-afk and bent in the bit, or runout in the drill spindle/chuck will widen the hole,, and drill bits do not drill real round holes anyhow
11:56 katsmeow-afk if you want a round hole, use a 6-flute reamer, you'll be amazed at the difference
11:57 katsmeow-afk or a 6-flute mill bit
11:57 rue_shop3 yea I bought a 100 peice set from china for $1
11:57 rue_shop3 :/
11:57 rue_shop3 (not)
11:58 katsmeow-afk i know, pricey, but after 2 days of messing with drill bits when i needed a real .510 *round* hole, i went and got a reamer
11:59 katsmeow-afk 13mm = .5118 , as near as i could get, and worked beautifully
12:00 rue_shop3 oh wow
12:00 rue_shop3 they blew the angle of the grub screw
12:00 rue_shop3 huh
12:01 rue_shop3 didn't notice that before
12:01 katsmeow-afk the 31/64 bit (.4844) turned a hole tween .50 and .48 , it wasn't round, and the 1/2 bit was drastically over .500 in 3 places around the hole
12:02 katsmeow-afk i wanted a loose slip on the shaft, which was like .505
12:04 GuShH ever heard of adjustable reamers....
12:13 zap0 loose slips on shafts; reamers.. this channel needs a NSFW
12:15 tsmeow-afk pours soap in zap's earholes and shoshes his head around to clean his
12:28 ace4016 lol
12:57 armyofevilrobots Woo, garage is getting closed in. :D
12:57 armyofevilrobots electrician putting in 40A next week.
12:57 armyofevilrobots rue_house / rue_shop3: ^^^
12:59 armyofevilrobots Also: http://sunshine.en.craigslist.ca/tls/4076882432.html
13:00 armyofevilrobots bit steep tho
13:26 GuShH armyofevilrobots: you need an electrician to do your electrical work? can't you just give the inspector a beer and do it yourself, the proper way
13:27 GuShH assuming there's one to begin with
13:27 GuShH that lathe is a friggin toy, don't waste your money on that.
13:28 GuShH you can get a used southbend with a crapton of accessories from an auction (someone who just died usually)
13:28 GuShH for a similar amount
13:28 GuShH that's a real lathe, any model.
13:47 rue_shop3 Hey Derek, Dave here at Dan's club house. My boy is working on a couple of projects.
13:50 armyofevilrobots COol!
13:50 armyofevilrobots .@GuShH; Yeah, I just posted because it's close to home
13:51 armyofevilrobots Although there aren't many southbends (or bridgeports for that matter) coming up for sale here in Canadia.
13:51 armyofevilrobots It's like nobody does fabrication in Vancouver.
14:06 GuShH armyofevilrobots: or they did but have long since sold the tools
14:06 GuShH now they sit on some old guy's basement
14:06 GuShH waiting for them to die.
14:07 GuShH it's not a real precision tool anyway, mostly marketing bs -- not worth the price, those taig. However, if you want to produce small parts and you want to CNC convert them, it's an OK alternative... assuming you can get one for half the price.
14:08 GuShH it's just too small for most things.
14:08 GuShH there's never a lathe big enough, sadly.
14:23 rue_house armyofevilrobots, hey
14:24 rue_house heh, a home bilt
14:25 rue_house armyofevilrobots, my lathe was from kms, china one, not bad but there are lots of improcements to do to it
14:46 rue_house katsmeow-afk, the pulley drilled out GREAT, true as I could ever expect anything to be
14:46 katsmeow-afk congrats,, wanna see my newest bruise?
14:46 rue_house unlike the gas line tap I got from ebay for my truck thats the same too-big size that I got from the local parts shop
14:47 rue_house now I suppose I have to hock two of them on ebay
14:47 tsmeow-afk is inside only because of the garbage smoke outside
14:47 rue_house hmm
14:48 rue_house I have to make up a frame for the pullies and motor
14:48 katsmeow-afk i haveto make that 12ton press, my mattock blade is curling around again :-/
14:49 rue_house you have to go lighter on these tools kar
14:49 rue_house kat
14:49 rue_house I ran a few strips of welding bead along the back of mine
14:50 katsmeow-afk a few strips? i had to weld on a whole more 6 inches because it wore off
14:51 katsmeow-afk [14:31] <katsmeow-afk> 278 PCS MOTOROLA 74LCX541D http://www.ebay.com/itm/390668047430
14:51 katsmeow-afk [14:31] <katsmeow-afk> good way to interface a 3v avr to the real world
14:51 katsmeow-afk 6 minutes, $10
14:52 rue_house bufers wont help me much
14:52 katsmeow-afk they will drive a lot of leds
14:53 rue_house most of the leds I'm getting now are 500-700mA
14:53 rue_house LaRgE DiE
14:53 katsmeow-afk with 76 nicks in here, someone should need a few
14:53 rue_house :}
14:55 rue_house http://eds.dyndns.org/~ircjunk/images/maddoc.jpg
14:56 rue_house http://eds.dyndns.org/~ircjunk/images/shovel.jpg <-- katsmeow-afk plan for a steel shovel for you, hot water tank, rest you know
14:56 katsmeow-afk 1n4004 1800pcs $10 ?
14:56 rue_house wow, 1800?
14:56 rue_house hmm I could use that
14:56 rue_house tho I spent $50 on ebay last night in an oops
14:57 katsmeow-afk 7 minutes, better hurry
14:57 katsmeow-afk heh, cute shovel, i like that
14:57 rue_house nope, $37 shipping
14:57 rue_house it digs FAST
14:57 rue_house I was surprised
14:57 rue_house I keep hitting hardpan
14:57 rue_house :)
14:58 katsmeow-afk 494 PCS MOTOROLA 74F244DWThis seller accepts PayPal
14:58 katsmeow-afk 2 Bids: $10.50
15:02 rue_house http://ctrlv.in/241652
15:02 rue_house plus $36 shipping
15:03 rue_house katsmeow-afk, ^^^ see?
15:03 rue_house if its from the states Its not worth shipping
15:03 katsmeow-afk ouch
15:09 rue_house (from most ebay sellers)
15:09 rue_house I think about $17 is the lowest I'v seen shipping
15:09 rue_house thats why I buy from china
15:10 katsmeow-afk i dunno, you "won" ~50 74F07 and shipping was only $1.60usd
15:10 rue_house I was a bit surprised that for $50 they missed the grub screw holes in that pulley tho
15:10 rue_house :)
15:11 katsmeow-afk i'm not surprised, it was an afterthought, the factory didn't do it, they did it by hand at the contractor's warehouse
15:11 rue_house *I* can hit it better by hand
15:12 rue_house its ok, dosn't matter
15:12 rue_house it'll still hold it
15:12 katsmeow-afk the sindle i bent on the bigg drillpress, so much metal was removed drilling a hole for a pin, it's a wonder it ever held together
15:12 katsmeow-afk reall,y a 1/2 chuck , 1 hp motor, 3/8 spindle, with a hole thru it too!
15:12 rue_house I thought you managed to get that straighter than it was when it was new?
15:13 katsmeow-afk yeas, i did, and used it before the move to Fla, but i have not put it back together since i got back to alaforkingbama
15:13 rue_house wow downpour
15:13 rue_house wow, is it a floor press?
15:13 rue_house not just a bench press?
15:14 katsmeow-afk if at all possible, i'd prefer to put in a 5/8 or larger spindle, if i can make one
15:14 katsmeow-afk yeas
15:14 rue_house cool
15:14 katsmeow-afk floor, stands over 6ft
15:14 rue_house oo big one
15:14 katsmeow-afk needs otehr accessories too
15:14 rue_house ought be 1hp
15:14 rue_house does it have double reduction?
15:14 katsmeow-afk no, single, like 1" to 6" is the slowest
15:15 rue_house and its a chuck not a morris taper?
15:15 katsmeow-afk i should prolly change out the 3600rpm to a 1800rpm someday also, it could use a slower speed
15:16 rue_house I'd like to add a second pulley set to mine
15:16 katsmeow-afk the spindle is a taper, has a threaded collar pinned on, and a locking thing on the chuck screws up onto the collar
15:16 rue_house doing 3/4" holes with a twist drill is really on the edge rpm wise
15:16 katsmeow-afk so the taper holds the chuck, the threads hold it on
15:16 rue_house its built like a mill
15:16 katsmeow-afk sorta kinds
15:16 katsmeow-afk sorta kinda
15:16 rue_house wow, look at it come down out there!
15:17 katsmeow-afk but a spindle with holes in it, turned down to 3/8 dia, a really great way to sell replacement spindles :-/
15:17 rue_house I'm gonna go check on the greenhouse gutter tank
15:19 rue_shop3 +~100L since yesterday
15:21 katsmeow-afk pretty good
15:21 katsmeow-afk i get 100 gallons per inch of rain in the outdoor water tank-pool
15:22 katsmeow-afk 100 gallons ~= 375 l
15:22 rue_shop3 is that being relativly maintenance free?
15:22 katsmeow-afk but it's a lot bigger than a barrel
15:23 katsmeow-afk well, i dunno, i didn't do anything to make the water fall into it
15:23 rue_shop3 I put a gutter on the greenhouse and put it into the 1000L stoarge tote
15:24 katsmeow-afk i have considered diverting the water pipe from the center of the roof, i could double the water that way, but i havea feeling it has more bird poo in it than i'd like to be drinking
15:26 katsmeow-afk tis 3pm, going to check to see if the air is bretheable again, and maybe check snailmail
15:58 katsmeow-afk .
16:04 rue_shop3 if I got any of these power cables wrong, the +24V will get crossed with the +5V
16:04 rue_shop3 maybe i'd better check them
16:06 katsmeow-afk put a pwr-check on each pcb?
16:08 katsmeow-afk simple relay and diode would do it, tween the 24 and 5, if the 24 is not higher than the 5, the relay does not pull in and give either one to the board
16:09 katsmeow-afk a 24v square mini telco relay should do it
16:10 katsmeow-afk you could put a 5.5v crowbar on the 5v
16:11 katsmeow-afk 4.7v zener and a decent to-220 pnp to hold the 5v down till it's fuse blows
16:12 katsmeow-afk or whatever your 5v really is (8v to feed onboard 7805's?)
16:13 katsmeow-afk cause if you put 7805's on the pcb and feed them off the 24v, then you wouldn't need a 5v feed
16:21 katsmeow-afk 4.7v zener, a small to-92, and a big npn with it's emitter on gnd
16:22 irkp Does anyone know how to hook up a crystal resonator to the T0 input of an AVR?
16:23 katsmeow-afk doesn't every avr datasheet say how to do that?
16:24 Tom_itx irkp i know how
16:24 Tom_itx is this a survey?
16:24 irkp Tom_itx: Sorry, no, I meant could anyone please tell me how.
16:25 irkp katsmeaw-afk: I did look in the one I was using, but I could check another.
16:25 katsmeow-afk anyone: There is no such nick or channel.
16:26 tsmeow-afk hasn't read *all* the data sheets, but pretty sure the 100-page sheets say how,, the 15 page sheets may
16:26 katsmeow-afk many peple in here use avr, but other than Tom, may not be here,,, but there is an #avr channel
16:26 tsmeow-afk suggests you do it Tom's
16:27 tsmeow-afk hands Tom the
16:32 Tom_itx http://electronics.stackexchange.com/questions/20889/how-does-this-capacitor-work-in-this-schematic
16:36 katsmeow-afk he's never seen a 3-legged cap or a resonator
16:43 irkp Tom_itx: The thing I'm wondering about with this though is that with the T0 pin, which can be used as the timer's clock source, is only one pin on the AVR. I'm not sure exactly what to hook the other side of the crystal to.
16:46 irkp Tom_itx: I think I may have just found a document that will help me.
16:49 armyofevilrobots http://www.atmel.ca/Images/doc8128.pdf
16:53 rue_shop3 ah yes
16:54 rue_shop3 I need to start power distribution on the hexapod!
16:54 rue_shop3 but I need to check these cables first
16:58 irkp Okay, so it appears to me that I need an op amp to do this. Correct?
17:22 rue_house irkp, for 32.768Khz?
17:23 irkp rue_house: Yeah.
17:23 rue_house on a mega32?
17:24 irkp rue_house; tiny85
17:25 rue_house ah, you prolly have to have an external oscallator with the 85
17:25 rue_house not enough pins... hi ian...
17:25 rue_house hah
17:25 rue_house on the mega32, you put it across two pins
17:25 rue_house any built-in osc needs 2 io pins to operate a crystal
17:26 rue_house you need another external chip
17:26 rue_house UNLESS
17:26 rue_house you run the whole avr at 32.768Khz
17:26 rue_house ;)
17:26 rue_house you using isp, you can do that
17:27 rue_house or we can get you a chip like a 74ls04 that can be used to make an external osc you can push into the pin
17:27 irkp Well I just tried to do that, using this to set the fuses: http://www.engbedded.com/fusecalc/ but now I seem to have screwed something. I've tried using the -i avrdude parameter with 120us delay, but still nothing.
17:28 irkp That is, setting the whole AVR at 32768Hz.
17:28 rue_house if you set it to external osc, you have to get an external oscillator, not crystal, to reprogram it
17:28 rue_house crystal != osc
17:28 irkp I set it to use a crystal.
17:28 rue_house hmm
17:29 rue_house the 32Khz crystals run on a different power level
17:29 rue_house I'v not tried to do it direct
17:29 rue_house how does the 85 do that?
17:29 rue_house ot enough pins
17:29 irkp It's got an XTAL1 and 2
17:30 rue_house what the clock section of the 85 datasheet show
17:30 rue_house (I have my hdands full)
17:31 irkp With regards to the fuses?
17:32 rue_house no with wiring
17:33 irkp Well, I don't have any caps with me, but are those _entirely_ necessary? At low frequencies?
17:34 irkp It shows two caps on bot pins going to ground.
17:35 rue_house they keep the freq stable
17:35 irkp So that would be why avrdude is not working.
17:37 tsmeow-afk sniffs the avr and thinks it's bricked and needs recovery proceedures
17:39 irkp Well, I'm sure I set the fuse bits right, its just that I don't have the caps to set up the crystal to program it. My program is running fine.
17:40 katsmeow-afk it's running with no crystal or resonator?
17:41 irkp No, it's just running with a crystal with no caps to stabilize it.
17:42 katsmeow-afk get caps, be happy, all done
17:43 irkp Yeah, I guess I'll just have to wait until then.
17:43 irkp Thanks everyone for the help!
17:49 Tom_itx rue_house are your chinese avrs smiling?
17:52 rue_shop3 irkp, it might not wanna work with a watch crystal
17:52 rue_shop3 I'm sure it can be done
17:54 irkp Well, my original though was to run it at 1MHz with the internal oscillator and then use the timer clock pin. This means the AVR is running fast (obviously) and i
17:54 rue_shop3 irkp, did you set it for low speed crystal?
17:54 irkp ... and I have one more pin to use.
17:54 irkp I think so, but let me check.
17:54 rue_shop3 you can also get an i2c date chip
17:54 irkp Low-freq crystal with largest startup time.
17:56 irkp rue_shop3: yeah, but that's less fun.
17:56 irkp I will probably eventually end up doing that, though.
17:57 rue_shop3 hang around a while, let me check a datasheet
17:57 rue_shop3 Ihave an 85 I can try... I think...
17:58 rue_shop3 hmm I dont
17:58 irkp rue_shop3: Although using the i2c chip would increase the chip count.
18:04 rue_shop3 :)
18:08 irkp rue_shop3: Oh, and, on another topic, you know that 7 segment module board I was trying to draw? I realized that I may be able to eliminate all the jumpers by clipping the extra ground and the decimal pins on the displays.
18:08 irkp (I don't need the decimal pins.)
18:08 rue_shop3 :)
18:56 rue_shop3 "you just took me apart with your eyes" "and I put you back togethor again!"
21:06 rue_shop3 kat, what temp does water boil
21:17 MrCurious 100C?
21:17 rue_shop3 I was told that the temp of the water would effect the flow rates of the boiler
21:17 rue_shop3 NOT
21:17 rue_shop3 in F
21:17 MrCurious aat STP
21:17 dunz0r Depends on air pressure.
21:17 MrCurious 232F?
21:17 dunz0r 212 according to almighty google.
21:17 Jak_o_Shadows Yeah, definitely depends on pressure.
21:18 Jak_o_Shadows Water is an ideal gas under specific temp/heats
21:18 dunz0r At "normal" pressure it's 100 regular degrees/212 freedom eagle degrees at least
21:28 rue_shop3 from 55F to 99F there is no appreciable difference in flow
21:29 rue_shop3 its an open system, no pressure
21:34 katsmeow-afk if the water is boiling in the boiler, the act of converting to steam and (possibly) back to water will cause anomolies in the flow
21:35 katsmeow-afk you assured me several times, it does not boil, and if the flow rate is high enough, you may be unable to transfer enough heat during the time the water is resident in the boiler
21:36 katsmeow-afk if the water is not moving, it likely will boil, you will need enough pressure to push any airlocked tube full of water again
21:36 katsmeow-afk 3 - 5 psi (measured above the exit pressure) should be enough at the boiler input
21:37 katsmeow-afk 3 -5 psi = 6 - 10 ft of water column
21:38 katsmeow-afk can i go back to bed now?
21:39 katsmeow-afk ps: water trapped under rust will likely boil, and if you get enough fluffy boiled up rust blocking a pipe, the water in the entire pipe will boil, and if it runs dry may melt out or rust thru
21:59 rue_shop3 boilerPumpOff
21:59 rue_shop3 sdklahfksad
22:02 rue_shop3 "KNEEL BEFORE ME" "how long before? will you give me a sign? do I lead?"
22:09 katsmeow-afk obviously you did not get the schedule
22:11 rue_shop3 ARG, PIPE HAS NO SHUFOFF!!!! WHY!!!!!
22:12 katsmeow-afk they don't make water cutoffs for emt, silly
22:21 rue_shop3 HOUSEpUMPoN
22:29 rue_shop3 iinteresting
22:30 rue_shop3 the larger pump that does the house, dosn't push as much as the smaller boiler pump
22:30 e_shop3 looks at the 1/4HP
22:30 rue_shop3 roughly 3.6gpm across the system
22:39 katsmeow-afk that's real slow
22:40 katsmeow-afk you wanna shoot it to the house,,, or, ideally, put that pump inside the house where it's waste heat can contribute to the house warmth
22:41 katsmeow-afk the less tme a given water sits in the pipe to the house, the warmer it will be when it arrives
22:41 rue_shop3 boiler pump is about 3.8gpm
22:41 rue_shop3 the house pump is 2.82/3.24/3.4gpm in low/med/high
22:42 rue_shop3 so if I'v seen the boiler taking on 20c, how many btu is that?
22:42 rue_shop3 rise of 20c at 3.8gpm
22:44 tsmeow-afk is asleep and does not
22:46 rue_shop3 68,400
22:46 rue_shop3 wow
22:47 rue_shop3 20c rise is 68k btu/hr
22:47 rue_shop3 nowonder I cant dump heat into the hosue fast enough
22:47 katsmeow-afk not too shabby for free heat
22:47 katsmeow-afk hmm?
22:47 rue_shop3 it cant do that long before it overheats and has to shut down
22:48 rue_shop3 http://www.advantageengineering.com/fyi/288/advantageFYI288.php?GPM=3.8&Inlet=122&Outlet=158&Submit=Submit&BTU=0&Tons=0.00
22:48 Jak_o_Shadows BTU is a silly unit.
22:48 katsmeow-afk oohh, you need faster water tot he house, plus prolly more water-to-air exhangers
22:48 rue_shop3 well, I dont get near that much drop in the house
22:48 rue_shop3 I have to go check the temp logs
22:49 katsmeow-afk you need an equal drop in the house, especially as you are passing *less* water
22:49 rue_shop3 yea
22:49 rue_shop3 this just proved it
22:50 rue_shop3 but I want to know the delta on the house, I want to know how much heat i *am* getting into the hosue
22:50 tsmeow-afk has long suggested moreexchagers, ever since you posted the pic of two of
22:50 rue_shop3 I have to go clean out the verry expensive flow guage I was lent
22:52 Tom_itx more heat exchage at the house?
22:52 tsmeow-afk wonders low long that "great stuff" can-o-spray-foam will last under 5psi of 160F w
22:52 Tom_itx oh, just caught up and read kat's comment
