00:12 rue_mohr trypsin, the more you do, the more you learn how to do and the more you get done
00:18 rrywolf flops back onto katsmeow-afk for bed
00:23 trypsin yeah, thanks, I will do it
00:46 ferdna i am still here
00:47 ace4016 cool...i guess
00:49 ferdna ace4016, =)
07:00 ShH wonders if Sunnyday is still making g
07:01 m_itx g
07:29 Sunnyday I will be but first I have to rescue the vacuum cleaner
07:47 GuShH Sunnyday: rescue it how?
08:38 rue_bed prolly has to replace the wheels, recharge the batteries and mod the code so it dosn't get stuck in cormers like it does
08:52 GuShH o.o
08:57 katsmeow-afk why not just make the corners rounder? that way flower pots fit better and stupid gods don't get stuck either
08:59 GuShH oh wow this 104 ceramic measures 60nF
09:00 katsmeow-afk lil outa spec
09:00 GuShH and blowing on it causes 10nF drop
09:00 katsmeow-afk maybe it's not a cap
09:00 GuShH it's definetly a ceramic cap
09:05 GuShH katsmeow-afk: cheap ceramics are very bad.
09:05 GuShH highly microphonic, very unstable and they tend to fail short if over volted
09:06 katsmeow-afk i know, there's different tolerance families in ceramics, some are waaaaaaaaaaay aweful
09:06 GuShH which are in the "cheap" region :p
09:06 katsmeow-afk if you need close tolerance, think poly's
09:06 GuShH I just check components before using them
09:07 katsmeow-afk but soldering them , or breathng on them can change the cheap one
09:08 GuShH of course
09:08 GuShH you can actually use them as thermistors.
09:08 katsmeow-afk i use ceramics when i canget them cheap and use them all over the place, like one per chip or more
09:08 GuShH I never bothered to plot the curve, but nothing a bit of interpolation can't solve
09:08 katsmeow-afk but they aren't repeatable
09:09 GuShH no improvised sensor is repeatable
09:09 GuShH except maybe silicon diodes these days
09:09 tsmeow-afk
09:09 katsmeow-afk silicon is
09:09 GuShH most diodes used to be highly mismatched back in the day, well the same goes for a lot of other parts...
09:10 GuShH I'm dying to mod this old scope to double the bandwidth but I need to get another scope just in case...
09:10 GuShH they low-passed the vert. amplifiers
09:10 katsmeow-afk err, many scope amps have dual paths
09:10 GuShH series resistor starves it as well as higher value resistors everywhere
09:11 GuShH katsmeow-afk: compared the schematics against the better model
09:11 GuShH same part numbers, except different values on the lower end model and a clear low-pass setup
09:11 GuShH there are some missing trimming components in the low speed version probably due to not requiring the extra stability or precision I guess
09:11 GuShH nothing too critical
09:12 katsmeow-afk iirc, every Tek scope i looked at had a low-freq dc steering path and a high-freq performance path, you can optomise better
09:12 GuShH katsmeow-afk: even modern cheap ass DSOs low-pass or perform software limiting
09:12 GuShH it's just cheaper to have one board instead of many, you simply design the high speed version and cripple it, marketing 101
09:12 katsmeow-afk DSO hasto do lowpass filtering, you can't sample below Nyquist without getting false aliases
09:13 GuShH I meant obvious limiting hardware
09:13 GuShH and/or software
09:13 GuShH But I don't want to try this without a backup scope, it would be foolish
09:13 katsmeow-afk you lowpass filter, and if you can afford it you then do a brickwall filter too
09:13 GuShH that's not what I'm talking about
09:14 GuShH I'm talking about obvious lets-limit-it-and-have-them-get-what-they-pay-for
09:14 GuShH I always joke you pay more for less, because usually the non limited scopes may have less parts inside.
09:15 GuShH Anyway, that philips scope guy is a flakey bastard
09:15 katsmeow-afk oh, roumor has it the 2467(?) scope is that way tween the 300 and 400Mhz version, but the roumor doesn't take into the account the MCP crt in the 400Mhz scope
09:16 GuShH Oh I checked the tube as well
09:16 GuShH it's the same on both versions, in fact this tek tube can go way over 40 meg
09:17 GuShH I think the power supply it's the same
09:17 GuShH from what I've seen the higher speed vertical amp uses more power
09:18 katsmeow-afk there's a 60Mhz scope that uses the same crt as the 100Mhz 7603, and the 7603 can be hacked to do 130Mhz cleanly (as if that's a big difference)
09:18 katsmeow-afk it does
09:18 GuShH 10 meg limited uses a 150 ohm in series to feed both parts, the 20 meg version jumps it and uses 22 ohm series per transistor
09:18 GuShH similar deal with the pull-downs and such
09:19 GuShH basically halving the values by paralleling another resistor on those will do the trick
09:19 katsmeow-afk err, maybe, prolly a lot more hasto be done
09:19 GuShH katsmeow-afk: any free extra bandwidth is welcomed :p
09:19 GuShH katsmeow-afk: about 10 modifications on the vertical amp total
09:19 katsmeow-afk k
09:20 katsmeow-afk be careful about such things as push-pull pairs being too slow to turn off at thehigher freqs, cause if they don't turn off, they'll both be on and pop themselves or the psu
09:21 rue_mohr I'v never put a lpf on a digital control line
09:22 katsmeow-afk i have
09:22 GuShH bleh, copying the higher speed schematic should in theory yield a good result, assuming the psu is the same (haven't checked)
09:23 katsmeow-afk n some circuits, a too-fast edge can make adjacent lines interfere, or cause reflections, or draw too much current attempting to charge line capacitances
09:24 katsmeow-afk sometimes, slowing th etransition makes the signal get there 5ns later, but it's much cleaner
09:24 katsmeow-afk and overall same signal bandwidth
09:25 ShH is comparing vert. pre-amps
09:25 katsmeow-afk this means you get 300 leds : 1 Reel 5M 3528 RGB NO-Waterproof Flexible Strip 300 LED 60leds/M Light 500CM
09:27 katsmeow-afk this means you get 300 leds : 3528SMD Red Super Bright Flexible LED Light Strip 16 Ft Reel
09:28 rue_mohr wonder how many on a full roll
09:28 katsmeow-afk 300, they reduce the reel to be 300 leds
09:30 rue_mohr 300 isn't a reel, its a wristband
09:31 katsmeow-afk heh
09:31 rue_mohr oh wait
09:31 rue_mohr 60 leds/m
09:31 rue_mohr thats a pre-wired RGB strip
09:32 katsmeow-afk yeas
09:32 katsmeow-afk both urls are
09:34 rue_mohr hmm how to turna an ascii character into a baudot character
09:35 katsmeow-afk obviously, teach it french
09:36 rue_mohr turnip hasa teletype machine hes got someone getting operational
09:36 rue_mohr I have baudot to ascii, ascii to baudot is more complex cause you might have to change mode
09:36 rue_mohr stupid 5 bit systems
09:38 tsmeow-afk asks how much turnip would pay for a teletype's papertape reader/pun
09:39 rue_mohr he has one
09:39 katsmeow-afk so........ $50 ?
09:39 rue_mohr ask him
09:42 rrywolf stretches out and y
09:43 Sunnyday Did any of you see last night's video?
09:43 furrywolf no
09:43 Sunnyday Making delrin gears by hot oil bathing old delrin in AVocado oil?
09:43 Sunnyday http://www.youtube.com/watch?v=CZHThkVRtMc
09:43 Sunnyday Enjoy!
09:43 furrywolf and if you're going to use videos for text+pictures content, I don't plan on seeing it today, either.
09:43 rue_mohr ah dear
09:43 Sunnyday You can actually see the delrin molten at 8:04
09:45 Sunnyday Any questions, feel free to ask
09:46 furrywolf yeah, when are you going to write a proper web site instead of fucking video?
09:47 katsmeow-afk for real, yo could even half-copy websites you see already
09:48 rrywolf hops on katsmeow-afk's lap and stretches a
09:48 Sunnyday I'm not good at writing web sites, I'm better at filming stuff as a picture says a thousand words and a video is thousands of pictures so it saves me from writing millions of words
09:49 tsmeow-afk cusses at the math : 50pcs@$2.25 sounds better than 200pcs@$14 until you calc you need 150pcs and s&h on the first
09:49 furrywolf if a picture is a thousand words, and it can be said in 500 words, use words.
09:49 furrywolf because the other 500 is wasted.
09:49 katsmeow-afk sunny, you can embed a video on a webpage same as a pic
09:50 katsmeow-afk youtube puts videos on webpages all the time
09:50 katsmeow-afk so does every tv station and news outlet
09:50 katsmeow-afk even i have done it
09:50 rrywolf hates trying to get information from v
09:50 katsmeow-afk i think rue has too, and Tom, and zhanx
09:50 Sunnyday I don't have a website, only a youtube channel and a facebook page, facebook is a crock of shit because you can only talk to people you know in person
09:50 katsmeow-afk i do to, really, cause i have no audio down here
09:51 furrywolf video conveys information much slower than text.
09:56 furrywolf yay, payday... and in an hour when stores open, I can go spend it all! yay!
09:56 e_bed expl
09:56 Sunnyday Come on, I haven't given you raw feed, I've cut most of it out only showing you what happens at various temperatures
09:58 katsmeow-afk what temp does the delrin melt, how did you stop it smoking, and what's it cost per cubic inch?
09:58 furrywolf need potting soil, ladybugs, drippers and tees, a trash can, forks, staples, oil, brake cleaner, evaporust, a wire baskets for the ultrasonic cleaner, food, molex connectors, paying the car insurance, paying the web hosting, paying domain renewals, ziplocks, ... and it'll all be gone.
09:58 katsmeow-afk we need text data
09:59 katsmeow-afk "potting soil" isn't soil anymore, it's ground up pine bark :-/
09:59 furrywolf gasoline, can't forget the gasoline...
09:59 furrywolf yes, it is. which is very, very good for those of us in climates where the roots rot on anything left outdoors in dense soil...
10:00 Sunnyday 175ºc I stopped it smoking by not burning, i.e. keeping the oil below 270ºc, avocado oil has the highest smoke point of any organic oil
10:00 Sunnyday delrin is nothing, its scrap
10:00 Sunnyday the avocado oil is expensive
10:00 katsmeow-afk furry, but *pine bark* ??
10:01 Sunnyday but reusable so long as u remain below the smoke point
10:01 katsmeow-afk why did you use an organic, instead of a petro-oil?
10:02 Sunnyday Suggest something with a smoke point above 300ºc
10:02 furrywolf I don't know what kind of bark it is, and it also has compost, peat moss, chicken manure, bat guano, and other stuff in it.
10:02 Sunnyday ?
10:02 furrywolf silicone heat transfer oil?
10:02 katsmeow-afk why above 300c, when you don't heat it above 175c ?
10:03 katsmeow-afk what's delrin cost in some cup-sized standard container?
10:03 Sunnyday Because even though the oil was above 200, it seems the stainless pan contents remained at about 140
10:03 Sunnyday I think a lot of heat is being lost due to radiation
10:03 Sunnyday I get Delrin for NOTHING
10:03 Sunnyday Just a trip to the bagpipes factory
10:03 katsmeow-afk geese, free is nice
10:04 katsmeow-afk ever heard of a stovetop double boiler?
10:04 Sunnyday It came as this stringy stuff from a CNC machine coated in coolant, I rinsed the coolant off and once it evaporates it heats up much more quickly. most of the fumes smelled like a machine shop, if either the oil or the delrin burns it stings your eyes
10:04 Sunnyday What's that?
10:04 furrywolf bleh, it's raining pretty heavily today.
10:05 furrywolf .49in/hr
10:05 katsmeow-afk fasten a pot inside a bigger pot, pour your oil into the space tween them, the delrin into the inner pot, the oil heats not only the bottom of the inner pot, but also the sides
10:06 Sunnyday That's what I'm doing already!
10:06 katsmeow-afk yoou need at least an inch gap tween the pots for heat convection to move the il around
10:06 katsmeow-afk oh, ok
10:06 Sunnyday The 2nd pot is afloat on the oil
10:06 katsmeow-afk but you siad the delrin is losing heat by radiation
10:06 Sunnyday and i swish it around to ensure consistant temp
10:06 katsmeow-afk i woldn't float it, i'd fasten it
10:07 Sunnyday Fasten it?
10:07 Sunnyday It worked great for the wax
10:07 Sunnyday melted it in minutes
10:07 katsmeow-afk and for delrin ?
10:08 Sunnyday About 40 mins
10:08 tsmeow-afk nominates sunny for the Eliza A
10:08 Sunnyday Until it Starts to melt
10:08 Sunnyday I think with a heavier load of Delrin would work better because it would sink into the oil more
10:08 Sunnyday And I've had it so when I tip the inner pan the delrin starts to move like honey
10:09 Sunnyday I'll take a photo of what the melted delrin vs the original looks like
10:12 Sunnyday HERE: http://i.imgur.com/OEf7F.jpg
10:12 Sunnyday Left is the molten rock solid delrin I didn't pour because Lexi came home
10:12 Sunnyday Still can be melted again and poured at a later date
10:12 Sunnyday The right is the huge bag of delrin offcut, stringy and flexible
10:13 Sunnyday The one on the left is like a rock I've tried bashing it wth a hammer on a bench vice and it stays strong
10:13 Sunnyday I think it is ideal for molding gears
10:13 katsmeow-afk idiot puter has the internal itself's OS in knots
10:13 Sunnyday although pouring this into the silicone mold has yet to be attempted. I will try again Tomorrow when my GF has a full day at work and I can use the kitchen and not get shouted at for not preparting supper and making a smell
10:14 katsmeow-afk the thing that looks like a black turtle was melted delrin?
10:15 furrywolf sounds like you need a workshop.
10:15 katsmeow-afk and less camera flash
10:15 Sunnyday Yes
10:15 Sunnyday Its the shape of the stainless pan
10:15 katsmeow-afk furry, we gave up on telling him to make smelly outside, not inside
10:16 Sunnyday Its always raining in Scotland, I'm poor I can't afford a workshop, I do what I can when I can with whatever I can get my hands on and I try to do thigns in novel ways that are cost effective
10:17 furrywolf divorce can be very expensive, and should be avoided.
10:18 Sunnyday http://i.imgur.com/VXhCd.jpg
10:18 Sunnyday I'm not married
10:18 katsmeow-afk divorce is also distracting
10:18 Sunnyday Never will be for that very reason
10:19 katsmeow-afk ah, so she can just kick you out?
10:19 Sunnyday No I can kick her out
10:19 Sunnyday Flat's in my name
10:19 Sunnyday :P
10:20 Sunnyday But it woudln't end up like that
10:20 Sunnyday I just have to be reasonable
10:21 katsmeow-afk ok
10:24 furrywolf bleh, need to order printer ink too.
10:24 katsmeow-afk hmm, 24 gigabyte harddrive caching controller
10:25 katsmeow-afk 24 gigabytes,, that about takes care of a simple FAT and sector table , now about the files themsleves .....
10:25 katsmeow-afk <cough>
10:26 katsmeow-afk i think 128megabytes file cache per drive should be ok, since they are data and text files?
10:26 katsmeow-afk ok, 256megs per drive
10:27 katsmeow-afk that will enable a fair amount of prefetch
10:28 Sunnyday Is this any good: http://www.ebay.co.uk/itm/K-Type-Digital-Thermometer-with-Thermocouple-Probe-50-C-750-C-Battery-/160703480381?pt=UK_BOI_Electrical_Test_Measurement_Equipment_ET&hash=item256aac823d
10:28 katsmeow-afk i dunno
10:30 furrywolf bleh, buying ink... there's another $15 gone.
10:36 GuShH Sunnyday: expensive for what it is
10:37 Sunnyday Will it do the job for getting a good reading on the avocado oil so I don't burn it?
10:37 rue_mohr I'm gone for the weekend
10:37 GuShH Sunnyday: basically an opamp, an asic or mcu with a lut and the lcd driving circuit...
10:37 rue_mohr nice tom
10:37 Tom_itx rue_mohr where you goin for the weekend?
10:37 GuShH Sunnyday: it'll work for that, but you should keep looking
10:37 rue_mohr but you forgot to make a hole for some of the cables
10:37 Tom_itx not done
10:37 GuShH Sunnyday: also get a metal k-type probe, not the exposed kind
10:37 GuShH the metal ones are for liquids
10:37 rue_mohr I'm a table in the mini maker fiaire in vancouver, but dont tell anyone
10:38 Tom_itx ahh
10:38 GuShH (which is the same thermocouple, potted inside a tube with a capped end...
10:38 katsmeow-afk no internet access at a maker faire?!?
10:38 rue_mohr hmm
10:38 rue_mohr I cant plug the laptop into my iphone
10:38 Sunnyday I bought it now
10:38 Sunnyday :(
10:39 Sunnyday What will happen if I stick the probe in 200 degree oil?
10:39 rue_mohr Tom_itx, how you gonna cut holes in there now that you went and filled it?
10:39 furrywolf wow, the ebay epson chip resetter actually works.
10:39 Tom_itx rue_mohr i'm still test fitting things
10:39 furrywolf I still don't have any ink, but now the printer thinks I do, so I can use the other colors. :P
10:39 rue_mohr thermocouples can take up to 1400
10:39 Tom_itx but have most of it in my head now
10:39 Sunnyday So it'll be alright?
10:40 rue_mohr I cant see, dd the box come with a backpan?
10:41 Tom_itx yes
10:41 rue_mohr what eh top right board?
10:41 Tom_itx http://tom-itx.dyndns.org:81/~webpage/cnc/psu/psu_index.php
10:41 Tom_itx pick your view
10:41 rue_mohr stepper driver?
10:41 Tom_itx those are for the control yes
10:41 Tom_itx various, stepper, io, pendant, limit switches
10:41 Tom_itx i'm gonna mount that today
10:41 rue_mohr erm
10:41 Tom_itx the plastic is gonna go
10:42 rue_mohr fins aren't on the outside?
10:42 rue_mohr sandwich the door betweent eh drivers and the heatsink?
10:42 Tom_itx huh?
10:43 katsmeow-afk i hope my boxes with doors look as well done as that
10:43 Tom_itx the heatsink should be in the air flow when closed
10:43 rue_mohr [outside] heatsink door drivers [inside]
10:43 Tom_itx i considered that
10:43 rue_mohr ah
10:44 Tom_itx that's the smaller heatsink i cut
10:44 rue_mohr looking good!
10:44 katsmeow-afk heck, i can't even get the paint on non-door-ed boxes to look right : http://designerthinking.com/images/variac_rack/DSCF2236mc.jpg
10:44 rue_mohr hows kats power supply?
10:45 Tom_itx i may mount a pc type plug for the power input
10:45 Tom_itx and need to add a fuse holder still
10:45 katsmeow-afk if i had to make a door for that, i wouldn't
10:45 rue_mohr kat, did you do that paint job?
10:45 Tom_itx i have it, just not installed
10:45 katsmeow-afk yeas :-(
10:45 rue_mohr how did you do that?
10:45 katsmeow-afk the BACK of the box looks better!
10:45 rue_mohr it looks neat, how did you do it?
10:46 katsmeow-afk spray paint, i kept changing the color, prolly painted over wet paint in a hurry to get it done
10:46 furrywolf bleh, forecast for the next week is rain.
10:46 katsmeow-afk but the paint is all wrinkley :-(
10:46 rue_mohr the consistency is really good
10:46 Tom_itx the right side of my box will have all the io fittings
10:46 katsmeow-afk yeas, i guess ,, i prefer Tom's box
10:46 Tom_itx katsmeow-afk, look for one cheap on ebay
10:46 rue_mohr I'm a sucker for blue and black :)
10:47 rue_mohr and guitar intros
10:47 Tom_itx one guy got one for $75 a couple weeks before i got that one for $22
10:47 Tom_itx shipping cost more than the box but it was still a bargain
10:47 rue_mohr kat, do you know if it was the same type of pint?
10:47 katsmeow-afk $75 is too much tho,, the shipping alone,, right
10:47 rue_mohr paint?
10:47 Tom_itx shipping was 25
10:48 Tom_itx so i got maybe 45 in it
10:48 katsmeow-afk no, may have been different, iirc it was all rustoleum
10:48 Tom_itx for an industrial enclosure it's a bargain
10:48 Tom_itx it's heavy
10:48 rue_mohr I'll have to try to do that sometime
10:48 katsmeow-afk to find one not already beat up is good too
10:49 rue_mohr it almost looks like you sponged it
10:49 rue_mohr huh
10:49 katsmeow-afk rue, the last pic taken of the psu is http://designerthinking.com/images/benchpsu/DSCF2753m.jpg
10:49 katsmeow-afk i have since done more rearranging
10:50 katsmeow-afk no, wait
10:50 katsmeow-afk not the last
10:50 rue_mohr do you need some more fans?
10:50 rue_mohr I think I have about 100 of the things
10:50 katsmeow-afk compare fans in http://designerthinking.com/images/benchpsu/lilfansm.jpg vs http://designerthinking.com/images/benchpsu/bigfansm.jpg
10:51 rue_mohr woof
10:51 katsmeow-afk bigfansm.jpg is the last pic taken last nite
10:51 katsmeow-afk woof??
10:51 rue_mohr big fans!
10:51 katsmeow-afk yeas, real blowy
10:51 katsmeow-afk 12vdc@150ma
10:52 rue_mohr gonna take that off the control transofrmers?
10:52 katsmeow-afk the lil fans in the first pic use more power than the big fans
10:52 katsmeow-afk no
10:53 katsmeow-afk the lates revision calls for the xformers to be where the heat sinks are in http://designerthinking.com/images/benchpsu/bigfansm.jpg , in which case i can put transformers 4-wide
10:54 katsmeow-afk that givesme 6 windings for control circuits, and one for the big fans and mot primary relay etc
10:54 Tom_itx rue_mohr should recognize that blue protective material i used
10:55 katsmeow-afk he sent you muscle stuff?
10:55 Tom_itx no
10:55 Tom_itx but it's the same stuff
10:55 Tom_itx local surplus here
10:55 katsmeow-afk yeas, i sent him a lil, iirc, few years ago, gave urls too
10:55 katsmeow-afk all i had was black, but it was cheap
10:56 Tom_itx they had black blue and yellow but the black i think would have been too small
10:56 rue_mohr hehe
10:56 Tom_itx and the yellow was alot bigger
10:56 tsmeow-afk
10:56 katsmeow-afk nowadays they sell it on ebay in hge kits for putting it on eeryting under a car hood
10:57 katsmeow-afk even radiator hoses
10:57 Tom_itx not good under a hood imo
10:57 Tom_itx big dust collectors
10:58 katsmeow-afk i agree
10:58 katsmeow-afk you going to do something about that cut ribbon cable?
10:59 Tom_itx that all gets rewired
10:59 katsmeow-afk !remember !archive Tom raised the bar on projects for us all again
10:59 furrywolf wow, I haven't been to harbor freight in a while, and their prices have gone up a lot.
10:59 Tom_itx but no, it's spare IO
10:59 katsmeow-afk yeas, they have, horribly so even
11:00 katsmeow-afk winches have doubled in price, generally stuff is 25% over a few yrs ago
11:01 furrywolf evaporust went from $19.99 to $29.99... a/c manifold set from $24.99 to $54.99...
11:01 katsmeow-afk furry, in fact, be careful they aren't charging more than Home Depot / Lowes
11:01 furrywolf there's no home depot nor lowes around here.
11:01 katsmeow-afk ok
11:01 furrywolf there's two main places to get tools here... a local hardware store, and a fastener store. both stock only american tools, with associated prices.
11:01 katsmeow-afk on one hose they were pushing in Bham last month, it was 2x theprice of a similar hose at local Home Depot
11:02 furrywolf then there's harbor freight.
11:02 katsmeow-afk garden hose, 75ft, high pressure
11:03 katsmeow-afk local water co would sometimes push pressure up to 80psi and up, now i don't worry about it, the pump is set at 50psi
11:03 furrywolf looks like the 12klb winch is on sale for $399 if you still need one.
11:03 katsmeow-afk i'd like to, but not going to spend that kinda money on that kinda stuff now
11:04 furrywolf I have two spare 6000lb winches... one is going to go on my subaru, don't know what I'm using the other for yet.
11:04 katsmeow-afk i find the baby winches, 1000lb, 2000lb, good as light movers, rollers, pinchers, lifters, draggers, etc,, but they are charging a lot more now
11:05 furrywolf I might put it on a receiver for the back of my jeep.
11:05 furrywolf but that involves first building a receiver hitch for the jeep...
11:06 katsmeow-afk i rolled the inner and outer face of these on 3 HF winches : http://designerthinking.com/images/bigboat/IMG_0029.jpg
11:07 furrywolf heh, good use for them.
11:07 furrywolf I want to get a crane for my jeep... probably buy instead of build.
11:09 furrywolf http://www.ebay.com/itm/Auto-Crane-3203PR-Autocrane-/140760642752?pt=Cranes&hash=item20c5fcf4c0 unfortunately they're ungodly expensive, so I might end up building one...
11:09 katsmeow-afk http://designerthinking.com/images/hullribform/IMG_0017.jpg
11:10 katsmeow-afk damn that's a lot of crane, you need an *really* good attachment point for those
11:11 furrywolf I was going to build a stand with 2 or 3 receiver hitch tubes in the rear bumper, so I can remove it when I don't need it.
11:11 katsmeow-afk that rolling rig ias adjustable for different diameters
11:11 katsmeow-afk that handtruck on the left in that pic was left in Fla
11:13 furrywolf a vehicle-mounted crane would really make moving stuff easier... I might just have to get some hydraulic rams and a pump from the scrapyard, and start building.
11:13 katsmeow-afk so was http://designerthinking.com/images/bigboatbowmaking/DSCF1466.jpg
11:14 katsmeow-afk furry, just a ladderrack made to take a load like a wing, would be enough, then you'd have a ladder rack too
11:14 katsmeow-afk err, like a winch
11:15 furrywolf you left the bow of your boat in fl?
11:15 katsmeow-afk yep :-((
11:15 katsmeow-afk and both hulls of the pontooon boat
11:16 furrywolf are they in safe storage, and will still be there later?
11:16 katsmeow-afk i could not afford the fuel to make another trip, my back was killing me and i could not reload them onto th etrailer, and so i swapped them for help loading what i could get loaded
11:16 katsmeow-afk nope, the guy scrapped them
11:16 furrywolf :(
11:16 furrywolf gave up on the move-into-a-boat-and-never-deal-with-hooomans-again plan?
11:16 katsmeow-afk nope
11:17 furrywolf building an even bigger one instead? :)
11:17 katsmeow-afk but hoomans cost me that time, and money and work, so my opinion of them hasn't improoved
11:17 katsmeow-afk nope, i haveto build it all over agian
11:20 furrywolf the problem with me and living on a boat, is even if I liked water and boats, I'd want one large enough to have a shop on board...
11:20 furrywolf and I'd end up building something huge.
11:21 katsmeow-afk you seldom need all tools out at once, so all you really need is a boat-wide tarp or roof, then lift things up to the deck as needed
11:22 furrywolf I have a hard time fitting all my crap in a large house. heh.
11:23 katsmeow-afk i understand, i do, 3000 sq ft of i do, but a lot of it is land-house related stuff, not shop or boat related
11:24 furrywolf and then I'd want a really huge motor... maybe stick a couple of retractable voith-schneider drives for tight-space maneuvering...
11:24 katsmeow-afk for instance, i don't need 27 fry pans on a boat, or 3 nukeboxes, or 6 recliners, or etc
11:24 katsmeow-afk voith-schneider drives = a long foot on an electric outboard thru a tube
11:25 Tom_itx kat
11:25 Tom_itx somebody said my box was the wrong color
11:25 katsmeow-afk crap, they did that you too??
11:25 furrywolf but that doesn't have the shiny factor.
11:25 furrywolf but, yeah, regulat azipods would be much easier.
11:25 katsmeow-afk shiney factor? it's in a tube, who can see it?
11:25 furrywolf regular
11:26 katsmeow-afk i didn't collect those 36v motors for nothing, yanno
11:26 Tom_itx Did you HAVE to recycle the beige paint too?
11:26 katsmeow-afk what?
11:26 Tom_itx and you dont have any spray paint?
11:27 katsmeow-afk Tom, i like it, it fits into shop/industrial environment nicely
11:27 katsmeow-afk mine, wrinkley blue, doesn't
11:27 furrywolf did you use krylon paint by any chance?
11:27 katsmeow-afk me? no
11:28 furrywolf krylon's crap always wrinkles for me. heh.
11:31 katsmeow-afk cost of dimm socket for memory : 67 cents ; cost of memory to go into it : $1.60
11:32 furrywolf heh
11:32 katsmeow-afk altho i have paid less than 60 cents for memory
11:33 katsmeow-afk i need to go do things irl
11:33 Tom_itx yeah
11:33 rrywolf needs to do, but is tired, and they all involve spending m
11:33 furrywolf to too
11:33 katsmeow-afk Tom, keep that baked grey enamel look, is fine with me, for what that's worth
11:33 katsmeow-afk bbl
11:34 furrywolf cyas
11:34 Tom_itx i'd considered painting it anyway back to the original grey maybe
11:34 Tom_itx maybe not
11:35 Tom_itx it's not too much of a concern
12:55 Tom_itx http://www2.electronicproducts.com/Zn_air_battery_supplies_72_h_off_grid_energy-article-pspo07_aug2012-html.aspx
12:56 Tom_itx katsmeow-afk, rue_mohr ^^
12:59 katsmeow-afk it's HOT outside, even under the tin roof over the drive, the tin converts visable lite to IR
12:59 katsmeow-afk yeas, but who SELLS Zn-air batteries???
13:00 katsmeow-afk last oem i corresponded with, 2 weeks ago, had an article saying they had bought a Zn-air patent and had it under developement for a year, but had actaully scrapped it
13:01 katsmeow-afk $600 is a lot pricey for a battery you cannot recharge
13:02 katsmeow-afk an Israeli firm had a Al-air battery under developement for several yrs, and not a thing to sell.
13:03 katsmeow-afk fact is, this is old technology, i dunno why it's not put to work
13:05 katsmeow-afk http://www.qsinano.com/ is a dead end, no links work
13:06 Tom_itx works here
13:07 katsmeow-afk great, where's their statonary cheap batteries? where's the data on what to do with dead batteries?
13:14 tsmeow-afk is so sure they have nothing, she isn't going to waste any time writing to ask abou
13:14 Tom_itx it was just a weekly email i get
13:15 tsmeow-afk
13:16 katsmeow-afk there was a flywheel energy storage company that installed a lot of very low impedance quick-charge-discharge capacity up north last year........ it's all been scrapped now , even tho it prooved it worked
13:17 katsmeow-afk no reason given for pulling it except *maybe* the cost of natural gas fell and power co decided to just leave the turbines running 24-7 instead of conserving fuel
13:21 katsmeow-afk afaik, in the last 8 yrs, of all the big alt energy plans, only one was built, and it was scrapped after a year due to union labor costs
13:22 katsmeow-afk and like furry said, when systems are removed from roof for any reason in Calif now, they aren't being replaced
13:23 katsmeow-afk this stupidity will one day come back to bite innocent humans in the ass, humans that will need the electricity can cannot have it, and cannot make it
13:25 katsmeow-afk without "alternative" energies, or nuclear, there's simply a limit to how much energy there is available to exploit by burning things
13:28 katsmeow-afk imagine there's no electricity to make the things that make "alternative" energy
13:29 katsmeow-afk nothing to power the trucks to mine and transport, or to power the refineries, or the factories,, or to make the fertiliser to grow food to feed the workers
13:30 katsmeow-afk Earth is just not an infinite fuel depot
14:33 furrywolf whomever wrote that was just copying some ad copy without even pretending to understand it, and much of it doesn't even make sense.
14:33 furrywolf "It is roughly half the weight of a lead-acid battery and has 11 times the equivalent energy per kilogram." .. huh? half the weight != 1/11th the weight...
14:35 GuShH furrywolf: they're using journalist units
14:39 furrywolf energy density is the only thing it has going for it, since it's so expensive you could buy a complete lead acid + solar panels setup instead...
14:40 furrywolf it's only 3.2kwh. for $600, you could get 300W of panels plus two lead acid batteries. the two batteries would come with 2.8kwh of energy already in them, just under the 3.2 of that system, and then you'd get another 0.2-2.5 kwh/day forever from the panels.
14:50 rrywolf bets the primary target is organizations spending other people's mo
15:21 rrywolf uses 4-space ind
15:21 furrywolf grr, wrong window
17:30 GuShH holy shit http://www.youtube.com/watch?v=m3KdpzL3Hkk
17:38 GuShH bah it's air powered, this is much better http://www.youtube.com/watch?feature=endscreen&NR=1&v=yUvzwF0cQfI
17:39 Tom_itx i've see the chevy v8 one
17:39 GuShH I don't get it why would anyone go through all the trouble just to make it air powered
18:57 yahweh Hey Rue, what day do you leave for the maker fair thing?
19:09 Tom_itx i think he's gone
19:09 Tom_itx or soon to be

21:06 zhanx redoing my cnc machine
21:06 zhanx http://i45.tinypic.com/168a886.jpg
21:07 Tom_itx seems to be a trend :)
21:08 zhanx why is that? I missed something didn't i?
21:08 Tom_itx http://tom-itx.dyndns.org:81/~webpage/cnc/psu/psu_index.php
21:08 Tom_itx last 2 pics
21:08 Tom_itx was last nights progress
21:10 zhanx nice
21:11 zhanx my power supply fits perfect at the bottom
21:12 Tom_itx i grabbed the box off ebay for $22 and shipping
21:12 Tom_itx nice heavy industrial box
21:12 zhanx you can't tell from the pic but that is transparent forest green acrylic
21:13 Tom_itx i thought it was one of those darkened mirrors
21:13 zhanx the other side backing is still on
21:29 zhanx tomorrow i get to wire up a top control panel to have buttons to move the xzy
21:29 zhanx with a digital readout
21:29 zhanx so i can use the probe properly and use buttons to jog the system to location and send info back to the computer
21:30 Tom_itx i'd like to make a dro for my spindle speed so i can get the feeds and speeds calculated a bit closer
21:30 Tom_itx mostly running by ear right now
21:31 zhanx the extra board i just got will allow me to do spindle control
21:32 zhanx with your probe, and that board it was time to upgrade the controller box since i have everything on hand now
21:33 zhanx i got 3 days off then work a week and i have block leave
21:33 Tom_itx i really like my pendant
21:33 Tom_itx i've used it quite abit already truing up stuff for that box i'm making
21:33 Tom_itx the heatsinks etc
21:34 zhanx i still need a probe for it but i will be ordering one soon
21:34 Tom_itx i haven't gotten mine back out of the box yet
21:35 zhanx sweet my oven gets hot enough to melt acrylic
21:35 zhanx i got a 4x8 sheet of it at work
21:35 Tom_itx i've used steel rod heated with a torch sometimes
21:56 zhanx thinking i might add a fourth axis to my cnc
22:00 Tom_itx once i get things squared away with the control and maybe make a dro for the spindle i wanna make one
22:08 furrywolf Today's Rain: 1.29 in
22:54 zhanx Tom_itx: what you think of the layout? http://i45.tinypic.com/2jg1649.jpg
23:47 katsmeow-afk layout is kinda particular on how you like to use it
23:48 katsmeow-afk or even what you call it
23:48 katsmeow-afk Tom says "pendant", i say "what?"
