00:00 rue_mohr I have a trailer, an old one before they made them adhere to the building standrards
00:00 katsmeow [23:45] <rue_mohr> furthermore, nobody up there [up there is Canada] would use insulation that thick, so a sketchy constructor would tear it in half
00:00 furrywolf this place is relatively uninsulated
00:01 rue_mohr no I was talking about in YOUR area
00:01 furrywolf where it has some, it's a thin (1/2") layer of fiberglass. all single-pane windows.
00:01 rue_mohr I'm suggesting that you, kat, can sell the insulation for some cash
00:02 tsmeow nods and then looks for a place out of the way to
00:02 rue_mohr but you have to sell it to a sketchy constructor because a 'creditable' one would a) not buy insulation from anywhere but a construction supply store, b) not be buying insulation that thick because they just dont understand what its for
00:02 rue_mohr :/
00:03 rue_mohr how big is my damned grinder
00:03 katsmeow i dunno
00:05 rue_mohr I have to go out to the shop and find out
00:07 rue_mohr but I dont want to
00:07 rue_mohr oooh
00:07 rue_mohr I dont knwo what I do want to do
00:07 katsmeow ping the big arm out there, have it measure and let you know
00:08 rue_mohr :)
00:08 rue_mohr with its 220kg grip, i can make the grinder about any size it wants
00:10 rue_mohr two are 4.5" and one is 4.5A, which is close enough
00:11 e_mohr removes the 5" cutting disks from his shopping
00:13 rue_mohr why are... 5" cutting disks cheaper than 4.5"?
00:13 katsmeow i dunno
00:14 katsmeow i buy the largest thin ones i can use, because when i use them, they become the smaller ones
00:14 katsmeow so i don't need to buy the smaller ones
00:17 rue_mohr http://www.princessauto.com/pal/product/8383556/Cutting-%26-Grinding-Wheels/10-pc-5-in.-Cutting-Wheels
00:17 rue_mohr http://www.princessauto.com/pal/product/8383507/?option=com_weblinks&view=weblink&id=36&catid=8
00:17 rue_mohr !??!?!
00:18 rue_mohr aha
00:19 katsmeow the cheaper ones are 0.125 thick, the thin ones are 0.045 , the thin ones will cut faster and make a smaller kerf
00:19 rue_mohr and cost more!
00:19 katsmeow the thin ones will use less motor power for the same cut
00:19 rue_mohr http://www.princessauto.com/pal/category/1000-400-115-100-100/Cutting-%26-Grinding-Wheels
00:19 katsmeow by$1, or 10 cents per disk
00:20 katsmeow a 1/8 kerf is spending a lot of time eating away metal if all you wanna do is cut it
00:21 rue_mohr but I tend to screw up and bite it evrey so often
00:21 rue_mohr which a thicker disk is gonna take better
00:21 katsmeow it's almost 3x as much metal to cut away
00:21 katsmeow k
00:21 rue_mohr I'll get 2 packs of each
00:22 katsmeow i use the thicker only when i need to do narrow grinding, or cut pvc where it will prolly bite the disk
00:22 katsmeow cutting pipe length wise certainly clamps down on the disk, you haveto keep inserting scrap steel behind the cutter to keep the kerf open
00:24 rue_mohr 4-1/2" super thin cutting wheel
00:25 rue_mohr it was the super thin ones I got last time
00:25 rue_mohr ok...
00:26 katsmeow did they do ok for you last time?
00:28 rue_mohr yea they were fine
00:29 katsmeow Diplomas read that the grads had completed "an approved progam of study" at their high schools
00:29 rue_mohr I can add a custom comment for shipping instructions, last time I said "pack with love" what should I say this time?
00:29 katsmeow the Washington Post reported that "the county paid $15,750 for the botched diplomas and an additional $6,587.50 for other certificates and shipping costs."
00:30 katsmeow i'd have ordered the normal diplomas with proper spelling, not the special ones
00:30 rue_mohr oh oh oh, I'm gonna say to take a coffeebreak after packing the box
00:30 katsmeow pack with motor driver chips
00:31 rue_mohr hahah pad with bags of doritos
00:31 rue_mohr :)
00:31 katsmeow yeas
00:31 katsmeow University of Texas at Austin had to apologize when the cover of their 2012 commencement program managed to leave out the L in "Public."
00:31 rue_mohr :) I'll do that next time, this time I'll say "Take a coffeebreak after packing this one."
00:32 katsmeow i was reading a legal doc by a lawyer that for many years said "bankuptsey"
00:32 katsmeow i pointed it out they were shocked and corrected it
00:32 katsmeow i'm like ..... spell checker?
00:39 rue_mohr maybe bankuptsey is now an official word in the usa
00:39 rue_mohr defiitly call for it
00:40 katsmeow i imagine if you sue to get bankuptsey, you can get it in the usa
00:41 rue_mohr arg, need supper
00:42 rue_mohr oh what do I least not want
00:42 katsmeow rice with catsup
00:43 rue_mohr oo I have half a can of gravy left
00:44 rue_mohr Tom_itx, did you provide this 1825S33 (microchip, smt) ?
00:45 rue_mohr whats a tl499?
00:45 katsmeow "packed in gravey"
00:45 rue_mohr have to be carefull, they might do it
00:45 katsmeow tl499 is a pwr supply controller
00:46 rue_mohr wonder if its any good
00:46 rue_mohr must be current mode
00:46 rue_mohr its only an 8 pin dip
00:46 rue_mohr I have a uPD2114 on the desk too
00:47 rue_mohr oh, two
00:47 rue_mohr imagine that 8k of ram
00:47 rue_mohr or 2k
00:47 rue_mohr geez, I'm gettin rusty
00:47 rue_mohr think its 8k
00:48 rue_mohr 4 bits 4k
00:48 rue_mohr 2111 was 1k

01:00 e_mohr makes a rawr face at furryw
01:01 rue_mohr hmm there is enough room in this old tape deck to put a computer
01:01 rue_mohr being I removed the tape mechanism
01:02 katsmeow how will you move the sd cards past the tape head then?
01:03 rue_mohr slow as I can, they aren't verry long ya know
01:04 rue_mohr last thing I posted was the waveform for the encoder right?
01:04 tsmeow ponders a new recorder: a tube of ferrite, with a vcr head moving up and down insid

01:08 rue_mohr you have a misplaced possibly
01:08 rue_mohr so you can see why it would be nice to just have a 2" pin
01:08 katsmeow it's not possibly to go there?
01:09 rue_mohr http://eds.dyndns.org/~ircjunk/robots/sparrow1/p1040051.jpg <-- angle shot
01:10 katsmeow before you had the tent and the workshop, where was all the stuff in the workshop and tent?
01:11 rue_mohr the stuff in the tent was stripped and sorted into the shop
01:11 rue_mohr the stuff in the shop is still there
01:11 katsmeow but 2 yrs ago, you had no shop there to hold th etent up
01:11 rue_mohr I had a rented space while building the shop
01:12 rue_mohr $500/mo
01:12 rue_mohr but going up
01:12 katsmeow oh, it was there, ok
01:12 rue_mohr when I worked out it would cost $8000 to make a shop, doing it was a no-brainer
01:12 rue_mohr $14000 later I have my shop
01:12 katsmeow big sign out front of store "we charge very little, but by shopping here you also agree to pay the outrageous rent on this place"
01:13 rue_mohr its already paid off tho
01:13 rue_mohr when I got the space it was like $300/mo
01:14 rue_mohr the jobs I had made that an acceptable rate for a hobby shop
01:14 rue_mohr when it went from 480 to 500 with a 'needs to go up again soon' I decided I couldn't take it anyore
01:15 katsmeow i need to find a way for you to make simple pages like Tom's or like my simple http://designerthinking.com/water.html sorta pages
01:15 rue_mohr not he landlords fault, he was running a mechanics shop, charging as little as he could
01:15 rue_mohr I have a php script
01:15 rue_mohr I just dont tend to use it
01:16 katsmeow k, but all we see is like http://eds.dyndns.org/~ircjunk/robots/sparrow1
01:16 rue_mohr yea

01:20 rue_mohr ah I see why that takes so long to load, all those 'thumbs' are 640x480
01:21 katsmeow ouch
01:22 katsmeow my dscf_1234m.jpg are medium (800x600) , the dscf_1234c.jpg are cropped, the dscf_1234s.jpg are small for 1/4 screen or less
01:23 katsmeow 800x scales nicely to 1/2 screen on most monitors, i think including the gigantic ones i don't have
01:24 katsmeow i just make a /s/ and copy all files there and then mogrify -resize 400x /s/*.*
01:24 katsmeow i just make a /m/ and copy all files there and then mogrify -resize 800x /m/*.*
01:24 katsmeow course, then haveto rename them
01:26 katsmeow dirlist = dir(root&"/m/")
01:26 katsmeow for loop = 1 to length dirlist do
01:26 katsmeow parse off the .jpg, add a "m", reattach the .jpg
01:26 katsmeow or
01:26 katsmeow replace all ".jpg" with "m.jpg"
01:27 katsmeow then rename the orig file and loop

02:14 rue_mohr its donated space, I didn't want to take up more space or processor
02:14 rue_mohr but I could prolly clean out 1/3 of the stuff without anyone noticing

02:17 rue_mohr -2x8mm
02:17 rue_mohr 36mm
02:18 rue_mohr drat, I cant find a common size thats 36mm
02:19 rue_mohr oh wait
02:19 rue_mohr 25.4mm
02:19 rue_mohr 52mm - 1 inch = 26.6mm
02:20 rue_mohr divided by 2 = 13.3mm
02:20 rue_mohr .52 inches
02:20 rue_mohr theBear, is 13mm a bolt size?
02:21 katsmeow does the 7603 and the 7904 use the same crt?
02:21 theBear umm, not super common, but i'm pretty sure you can get anything at least to 15mm easily
02:21 rue_mohr !! I dunno kat!
02:21 rue_mohr no I mean diamiter
02:21 rue_mohr I dont have a standard metric ref
02:21 theBear it'd be called M13 i guess
02:21 theBear so do i
02:22 theBear well that's for a standard machine thread
02:27 rue_mohr hmmm

02:29 rue_mohr if I use 1.25" pin, then 10mm roll pins would leave .2mm play
02:30 rue_mohr 1-3/8 is next up
02:31 rue_mohr 8.5375mm ...
02:32 rue_mohr with 5/16 roll pins
02:32 rue_mohr 20 thou
02:33 e_mohr th
02:33 rue_mohr thats not bad
02:34 rue_mohr so 2" pipe, with 1-3/8" pin, and 5/16" roll pins
02:35 rue_mohr I wonder if a 1-3/8" bolt costs more or less then bar stock
02:41 katsmeow more, it ha a head and threads added to it
02:41 katsmeow keep in mind, no bolts/rod/tube comes exactly the size it says
02:42 rue_mohr I only see up to 1-1/4" available from most places
02:42 rue_mohr eeek, the 1-1/4" comes in packs of 70, and cost $1000+
02:43 theBear eeek
02:44 katsmeow eeek
02:45 rue_mohr materials for this knee are being a problem
02:48 rue_mohr I think I should look for some abandoned hydraulic cylinders
02:49 katsmeow or make your own, look for DOM tubing for the cylinder barrels
02:49 rue_mohr no for the metal
02:49 katsmeow you're lucky you can cast pistons
02:49 katsmeow o
02:49 rue_mohr the ram would be the size range for what I'm seeking
02:49 rue_mohr I suppose I should work out how many of these joints I need to make
02:49 katsmeow why not use the barrel of a hmemade cylinder as the joint's main actuator AND one of the bones ?
02:50 rue_mohr but they shouldonly take up a few inches of stockeach
02:50 rue_mohr I cant picture what your saying
02:51 katsmeow the cylinder is a big heavy hunk of tubing, no? and yoou wann make the skeleton of tubing no? but why use pricey tubing for both, if you can work out how to use one hunk of tubing to do both jobs?
02:52 rue_mohr I have tubing for the main frame
02:52 tsmeow ponders for the right w
02:52 katsmeow ok then, i give up
02:52 rue_mohr its a good thought
02:52 rue_mohr but I'm ok there
02:52 rue_mohr I just need to solve the hinge problem in a way I'm gonna accept
02:53 theBear hmm... what should i accept at the pawn shop for a 2*450w 2r.u poweramp that i literally haven't even considered using for almost 10 years, but is in very near new condition ?
02:53 rue_mohr $800?
02:54 theBear heh nah, i just checked the web machine, seems like everything else, they aint worth what they used to be, cos new ones are so dirt cheap
02:54 rue_mohr katsmeow, do you know a bolt size that fits in 1/2" or 3/4" sch 40 steel pipe?
02:54 katsmeow no, but you have a nice chart somewhere that lists those
02:54 rue_mohr at descent hinge quality?
02:55 theBear decent
02:55 theBear :)
02:55 rue_mohr no I ahve a chart fo rhte pipe, but the bolt
02:55 theBear descent is doom with a tiny spaceship :)
02:55 katsmeow afaik, no non-metric bolt fits 1/2 or 3/4 pipe without a ton of slop
02:55 rue_mohr heh
02:55 rue_mohr hmm
02:55 rue_mohr wonder how the metric ones fair
02:55 katsmeow fare
02:56 theBear lol
02:56 theBear we only do it 'cos we love you rue
02:56 rue_mohr I been thinking of making a translation machine
02:56 katsmeow :-)
02:56 rue_mohr a sentient one that could make advanced corrections
02:57 rue_mohr repeat things slowly to people who cant understand them
02:57 rue_mohr maybe even go on the long long overly detailed explinations of simple concepts for people
02:57 theBear hehe i like the last bit, patronised by a machine
02:58 rue_mohr stuff that I dont have patience for
02:59 theBear heh, just like my home-based surgery practice <grin>
02:59 rue_mohr something that could let me speak to people at full speed
02:59 rue_mohr always having to talk slow for people
03:00 rue_mohr I get borred 1/4 way thru what I'm saying
03:00 rue_mohr sometimes to the point I forget helf way thru how it ends
03:01 theBear yer tlaking to the wrong people then :)

05:00 katsmeow as if this is a major criteria of the space flight
05:06 Steffanx Yeah it is
05:09 katsmeow in what way?
05:19 theBear has a woman ever been an active functioning astronaut before ?
05:27 iR0b0t1 Um
05:27 iR0b0t1 I think so
05:27 Steffanx Don't think, be sure :)
05:29 katsmeow several
05:34 katsmeow-afk Peggy A. Whitson holds the record for the most time in space by a woman, 377 days.[13]
05:35 theBear holy crap, i guess it's unimportant then
05:42 katsmeow-afk http://en.wikipedia.org/wiki/List_of_astronauts_by_name ,, 555 of them, but there's no list by sex or by gender or hair color
05:52 katsmeow-afk From September 1, 2010, 727 jetliners (including those with a hush kit) are banned from some Australian airports due to noise.[24]
07:47 theBear what's a hush kit ? not like you can just build a new exhaust for a jet engine like with a internal combustion
08:53 rue_bed you just hush it like you do a fan
08:54 rue_bed treat the blade tips and break up the edges
08:54 Tom_itx what? redesign the rotor blades?
08:54 rue_bed I'd presume
08:54 rue_bed turbine blades
08:55 theBear hmmm, makes sense
08:57 Tom_itx the smaller jets around here still get a little 'whistle' sound at certain rpms
09:00 Tom_itx rue_bed seems you've been working too much latel

09:15 rue_mohr how do you think I manage to pay for my life! :)
09:15 rue_mohr I have to accumulat about 2M by the time I'm 65 so I can retire
09:15 katsmeow-afk no, you baffle the exhaust some, and addl cowling to diect airflow intot he ehaust stream

09:18 rue_mohr food, after shower is food
09:28 katsmeow-afk http://en.wikipedia.org/wiki/Hush_kit
09:40 katsmeow-afk i got no sleep last nite
09:41 katsmeow-afk couldn't
09:41 katsmeow-afk did draw some lines on things, in pencil, pen, and majik marker
09:50 rue_mohr were they laying in the grass or chasing prey across the fields?
09:52 rue_mohr well I dont have to leave fora while yet
09:53 Tom_itx working today?
09:53 rue_mohr can anyone suggest a good interface for manipulating 3d points?
09:53 Tom_itx cad cam
09:53 rue_mohr yea, there is a homeshow I'm part of the table crew for
09:53 Tom_itx maybe you'll find a hawt chick there
09:53 rue_mohr which one?
09:53 Tom_itx any of several
09:54 Tom_itx solidworks is good
09:54 Tom_itx will even let you do stress analysis
09:54 rue_mohr for manipulating points and lines, not 3d objects
09:55 rue_mohr no I'm making a program for building and editing 3d stick figures
09:55 Tom_itx what did you test your buddy legs on?
09:55 rue_mohr I need interface ideas
09:55 rue_mohr that was an opengl rendering
09:55 Tom_itx povray?
09:55 rue_mohr for the fancy 3d images yes
09:55 rue_mohr but that has nothing to do with visually editing 3d stick figures
09:56 Tom_itx you see stuff like that on the web for kid math problems where they can drag the point of a triangle etc
09:56 rue_mohr but mine is for 3d points
09:57 Tom_itx so add another axis
09:57 Tom_itx the viewer on my cad does that
09:57 Tom_itx it has a 'dynamic' view mode
09:57 Tom_itx where i can drag the image wherever i want it
09:57 rue_mohr one view and just be able to zoom/translate/rotate?
09:57 Tom_itx most cad will do that
09:58 rue_mohr well I'm making this from scratch
09:58 rue_mohr its not a cad program
09:58 rue_mohr its for building bvh trees
09:58 Tom_itx reinventing the wheel?
09:58 rue_mohr what is a bvh tree you ask
09:58 rue_mohr I keep telling people
09:58 katsmeow-afk what is a bvh tree
09:58 rue_mohr no, this is for 3d motion capture
09:58 Tom_itx there are also robotic arm learning programs
09:59 rue_mohr no, this is for many things
09:59 rue_mohr I need to figure out how to make a cad editor for 3dpoints and lines
09:59 katsmeow-afk how do you know that?
10:00 rue_mohr what do I know that you want to know how
10:00 Tom_itx all of it
10:00 m_itx sucks rue_mohr's brain
10:00 katsmeow-afk camstudio?
10:01 katsmeow-afk freecad?
10:01 rue_mohr there aren't free programs for linux for editing bvh files
10:01 Tom_itx he doesn't want a cad program. he wants to write one instead
10:01 rue_mohr that run
10:01 rue_mohr I give up
10:01 rue_mohr figure it out myself
10:02 Tom_itx you never said what a bvh file was
10:02 katsmeow-afk and i even asked
10:02 rue_mohr you havn't listened every time I'v talked aboiut it
10:02 rue_mohr remember the youtube video of the stick figure dancing?
10:02 Tom_itx you tend to ramble alot
10:02 Tom_itx i skim alot
10:03 katsmeow-afk i got zero sleep last nite,and i even laid down and tried, so i forgot
10:03 Tom_itx i must not have an answer for you then
10:03 rue_mohr http://www.youtube.com/watch?v=P75b7vqQWRQ
10:04 rue_mohr a bvh file contains a skelatol definition and a motion data set
10:04 rue_mohr its used in movies for motion capture
10:04 Tom_itx a simulator
10:04 rue_mohr no
10:04 rue_mohr motion capture
10:04 katsmeow-afk and bvh stands for Bahawal Victoria Hospital
10:04 rue_mohr M O T I O N C A P T U R E
10:05 katsmeow-afk look! the hospital, she is in motion, capture her!
10:05 rue_mohr I can use the system to record movements for the robots
10:05 katsmeow-afk http://en.wikipedia.org/wiki/Bounding_volume_hierarchy
10:05 Tom_itx did you make that video?
10:05 rue_mohr yes
10:05 Tom_itx how?
10:05 rue_mohr from a bvh file that I downloaded off the interwebs
10:05 katsmeow-afk with numbers
10:05 Tom_itx oh
10:05 Tom_itx so you cheated
10:05 rue_mohr and the program I MADE to render it
10:06 Tom_itx i remember that now
10:06 Tom_itx we searched quite a while for files
10:06 rue_mohr I seem to have the only program that can take ANY bvh file and render it without crashing
10:06 rue_mohr http://en.wikipedia.org/wiki/Biovision_Hierarchy
10:07 Tom_itx http://www.bvhacker.com/
10:07 e_mohr stands up and wanders off to go get dre
10:07 rue_mohr Tom_itx, every program I tried crashes
10:07 katsmeow-afk at position 0.25 in http://www.youtube.com/watch?v=z2xWgEdiTwc&feature=relmfu
10:07 katsmeow-afk what are you pointing with?
10:08 Tom_itx i guess i can't help you then
10:08 Tom_itx if you've searched every program already
10:08 katsmeow-afk that odd brown thing pointing at the display
10:08 Tom_itx https://github.com/akjava/BVH-Motion-Creator
10:08 rue_mohr heh thats my finger
10:08 rue_mohr with a welding glove
10:08 katsmeow-afk oohh,, k
10:09 rue_mohr Tom_itx, I want to find good ideas for a 3d interface
10:09 rue_mohr hahahaha maybe I should make the program work ith 3d red/blue glasses

10:13 katsmeow-afk FIANLLY, someone <glares at rue> operated a "air muscle" with water : Air is lighter, but we have tested with? water and get more force, and ~60X increased closed valve stiffness.
10:15 rue_mohr and you would need vlves with 60x the orifice to get the same motion speed
10:15 rue_mohr :)
10:16 katsmeow-afk they exist
10:16 Helios The larger the valve the lower the pressure will be, you will need significantly larger volumes of gas/liquid to get the same pressure a smaller origice valve had
10:17 Tom_itx or multiple valves acting in unison
10:17 katsmeow-afk heh, guy made his own U2 spy plane: he put mirco engines with folding props on a glider
10:19 katsmeow-afk a moderate sized ring valve built coaxially tot he muscle could easily have as much open area as the muscele cross section
10:23 Helios Tom you are correct, the Russians discovered 3 rocket engines with 4 vales were more powerful that a larger than combined 1 F-1 rocket engine used on the moon program
10:23 Helios RD 171
10:24 Helios They shared the same turbopump and fuel tank however
10:24 katsmeow-afk or any 4-valve-per-cylinder car engne
10:24 Helios Katsmeow, another good example
14:11 home lol
14:11 home I need to know how to program my
14:11 home PIC
14:11 home on xubuntu
19:21 Helios Good evening
19:21 Helios How are you gentlemen?
20:14 iR0b0t1 Quite cheery, old chap.
20:17 Helios Good I am pleased to hear it
20:17 Helios I've been talking to some people about building a big spaceship
20:36 rue_mohr I'v got an eninge, you got a power supply?
20:37 rue_mohr he
20:37 rue_mohr damn left
20:39 rue_mohr the reason most of the bvh programs dont work with any bvh file is because they rely on a fixed skealton
20:39 rue_mohr the skelaton is defined in the bvh file and can be anything
20:39 rue_mohr for example if you take bvhhacker and try to load the frame of a cat, it will prolly just crash
20:40 rue_mohr my program will open any file
20:43 Tom_itx rue_mohr, what about blender?
20:44 rue_mohr not for creating and editing bvh files
20:44 rue_mohr for using them , yes
20:45 Tom_itx oh ok
20:51 rue_mohr the othe important thing about the library I made is that I can combine it with the ssc library I wrote
20:51 rue_mohr so you can have a bvh file control servos
20:56 rue_mohr so by 27?
20:56 rue_mohr hehe wrong window
21:30 furrywolf yay!!! my landlord's son finally moved "the tumor", as named by the last person who had it sitting in their yard for way too long. I can actually park in the driveway instead of the street, for the first time in 2.5 years.
21:47 katsmeow-afk whatwas it?
21:51 genesis an old van ?
21:53 katsmeow-afk <shrug>
21:54 katsmeow-afk around here such a vehicle would just get lighter and lighter till there was nothing left
21:56 genesis erosion =)

22:04 katsmeow-afk does one,, oh wait, humans do
22:04 tsmeow-afk cusses a
22:04 furrywolf a chevy blazer on 44" tires, about 2ft of lift.
22:04 furrywolf it kept growing, hence the name...
22:05 katsmeow-afk kept growing?
22:05 furrywolf bigger tires, more lift, more mold, more spare parts spread around it...
22:05 katsmeow-afk someone who did ot live there kept coming by to add to it??
22:06 furrywolf the last owner had it in a friend's yard, where it was a perpetual unmoving project, and it acquired its nickname. my landlord's son bought it, promptly broke several parts on it, then parked it here ~3 years ago, occasionally working on it...
22:07 furrywolf blocking my driveway.
22:07 furrywolf brb, parking my truck
22:32 furrywolf yay, first time I've had my truck in my driveway.
22:34 tsmeow-afk goes outside to leave it a pres

22:36 tsmeow-afk thinks furry must *really* like pizza to be laying it it so comfort
22:37 katsmeow-afk it was such a good $5 pizza, too
22:37 tsmeow-afk slides it out from under the f
22:37 furrywolf didn't you learn with the pasta? I'm quite good at squishing under other things on laps. :P
22:38 katsmeow-afk please remove your furr from the pizza, and we'll be even?
22:38 furrywolf first you stick your nose under whatever it is, then you lift, then you wiggle forwards with your legs sticking out behind you, so you end up on someone's lap without knocking over whatever was on their lap before, and it end up sitting on top of you.
22:38 katsmeow-afk ah
22:39 katsmeow-afk so a warm pizza is like an electric blanket?
22:40 furrywolf you're making me hungry.
22:40 furrywolf and I spent all my food money on solar parts.
22:41 katsmeow-afk i want one good food item per week, even if it's 3 days of munching on a $5 pizza, or one $3 doublecheese burger
22:41 katsmeow-afk the rest of the week it's ramen, pasta, and pb&j
22:41 furrywolf heh
22:42 katsmeow-afk altho i must say i can make a deeeeeeeeeeeeeeeeeelicious pasta, in different ways
22:43 katsmeow-afk prolly not up to your standards, but i scarf it down
22:43 furrywolf my standards are pretty low.
22:43 furrywolf I can't cook worth crap.
22:44 katsmeow-afk i soooooooooooooooooooooooooooooooooooooooooooooo miss having a garden,, and i dunno if it's worth it now with the humans putting a lite dust of ashes from trash fires on everything each ite
22:44 furrywolf my pasta consists of boiling noodles, straining them, then dumping on a jar of pasta sauce.
22:44 katsmeow-afk it's less about cooking, more about seasoning
22:45 katsmeow-afk look for the seasoning aisle, find bbq-meat-baking packets, find rarer (in the usa) seasonings like tumeric, cumin, oregano, etc
22:45 katsmeow-afk boil, strain, add butter, season to taste
22:46 katsmeow-afk less than a $1 per packet, lasts several meals, depending on meal size
22:46 katsmeow-afk but if i cold have a garden, i'd use 1/2 the pasta, and add chopped veggies
22:47 furrywolf or add a bit of garam masala...
22:47 katsmeow-afk anything, really
22:48 katsmeow-afk diced/pounded cheaper meats work too
22:48 katsmeow-afk or shredded, etc
22:48 furrywolf hrmm, I have vindaloo sauce, and frozen chicken breast nuggets...
22:48 katsmeow-afk you can alwasy use so many veggies that you can chill the pasta and then add it, and call it a salad instead of pasta
22:49 katsmeow-afk $25 mini-blender and you're all set then :-)
22:50 rrywolf very much likes indian
22:51 katsmeow-afk me too, as long as it doesn't eat thru my stomach before i am done eating it
22:52 katsmeow-afk i keep bottles handy of cumin, curry, allspice, tumeric, and a flavorful but not so hot black pepper
22:52 furrywolf it's very hard to make a dish I find too hot.
22:52 katsmeow-afk then there's the bottles of Brit/Eu flavorings, which i like separately
22:54 katsmeow-afk humans here just don't understand that "spicey" does not mean "empty the red pepper chips on it"
22:54 furrywolf red pepper isn't even spicey. :P
22:54 katsmeow-afk don't haveto tell me
22:56 furrywolf if you want spicey, I have some hot pepper starts I can send you, but you'd need a garden first.
22:56 furrywolf I have a spare Trinidad Moruga Scorpion start, 2,000,000-ish scoville...
22:57 katsmeow-afk yeas, well, the day i came home with enough 5gal buckets to make a serious start on a garden, the neighbor had the whole end of the subdivision buried n smoke, and everything the next morning had soot on it, i cannot eat food with soot in it
22:58 katsmeow-afk i don't like scoviles, i buy pepper for flavor, not paint peeling
22:58 furrywolf heh
22:58 furrywolf I haven't tried them yet, won't be any peppers until fall.
22:59 furrywolf I generally find most hot peppers pretty flavorfull.
23:00 katsmeow-afk sure, if you can get the capsaicn ut of them
23:00 furrywolf well, it takes a lot before I find them hot.
23:00 katsmeow-afk k
23:01 katsmeow-afk note to self: if furry serves dinner and says it's hot, get fire extinguisher
23:01 furrywolf heh
23:01 furrywolf I have a bottle of Dave's Insanity Sauce sitting next to me... :P
23:01 furrywolf and a guy from ##electronics sent me some homemade stuff that's pretty good
23:01 katsmeow-afk i wish i had a bottle of Bailey's next tome
23:02 genesis http://www.4x4offroads.com/image-files/1977-chevy-blazer-1990-body.jpg hu it's cool :S
23:03 furrywolf Bailey's is... alcohol?
23:03 katsmeow-afk and a good milk cream , the taste resembles chocolate
23:04 katsmeow-afk that pic is staged
23:04 rrywolf doesn't drink, so doesn't know liqu
23:04 katsmeow-afk no way that truck can be at that angle n the road with the wheels straight
23:05 furrywolf katsmeow-afk: sure it can
23:05 katsmeow-afk only by sliding the rear
23:05 katsmeow-afk and i see no piled up dirt
23:05 furrywolf why?
23:05 furrywolf it's got 15ft behind it
23:06 katsmeow-afk if you back that truck up witht he wheels as is, in 10ft it will be in that flower patch
23:06 furrywolf yes. but that's why steering wheels exist.
23:06 katsmeow-afk it can't do a 45 degree turn in 10ft and keep the wheels str8 and be wher it is
23:06 katsmeow-afk look behind the passenger side rear wheel
23:07 furrywolf looks doable to me, and I've done that...
23:07 katsmeow-afk what dirt is textured there wasn't done by a 4x4 driving across it
23:08 katsmeow-afk sure, i have had a vw sideways, the 280zx sideways (lots more than i wanted to even), my F250 sideways, all of it mostly on purpose
23:08 furrywolf nothing looks wrong to me, and from the popped tire, fully compressed struts, etc, the car definitely looks to have the weight on it.
23:08 katsmeow-afk i do not think the tire is popped
23:09 furrywolf could also have been deflated to lower the bumper
23:09 furrywolf for easier climbing
23:09 rrywolf has done enough redneck st
23:10 furrywolf a friend and I parked on top of a subaru wagon once.
23:10 furrywolf (beater that he was scrapping)
23:10 katsmeow-afk you hurt a poor defenceless practical subaru wagon??
23:10 furrywolf it was ready to be scrapped. not really any good parts left, and we pulled the ones that were before it went to the junkyard.
23:11 tsmeow-afk hates scrapping things, even when it's the only op
23:11 genesis katsmeow-afk : i did homemade bailey some times
23:11 tsmeow-afk
23:11 genesis cheaper and easy .
23:11 furrywolf it was a woods beater, with no good panels left, missing glass, no lights, blown tranny, and THREE, yes three, broken half-shafts.
23:11 katsmeow-afk it's only two ingredients?
23:11 furrywolf one-wheel drive.
23:11 genesis there are some eggs
23:11 katsmeow-afk ah
23:11 genesis chocolate milk cream , whysky
23:12 furrywolf the passenger rear wheel was the only one with a half-shaft. :)
23:12 genesis and others things.
23:12 katsmeow-afk and spices on bbq days,, er, holly days
23:13 furrywolf when the spider gears in the diff exploded, he welded the differential into a solid lump, hence why it kept driving with only one-wheel drive rather than just spinning the other stub shaft.
23:13 katsmeow-afk ah, i was wondering
23:15 furrywolf being a woods rig is hard on vehicles. heh.
23:16 katsmeow-afk i know, i had 40 acrs once, i cut the pines off part of it for pasture , trucked the big pine out as pulpwood and used the small stuff as winter heat
23:17 katsmeow-afk got me exercise, paid the fuel and insurance bill for both vehicles, cleared the land, good deal all the way round
23:19 tsmeow-afk luved the smell of buttered toast on the woodheater, with onion salt and garlic powder o
23:20 rrywolf hates spending time making food, and preferrs stuff that can be done in the microwave with one or two st
23:21 katsmeow-afk toast *is* easy: put on heater, splat on butter, when melted sprinkle spices, before it burns, take it off and eat it
23:22 furrywolf put on butter, put in microwave, hit 30 seconds, wait, eat.
23:22 furrywolf I really regret any time spent cooking... it's time spent just to feed myself, rather than doing anything lasting or productive...
23:23 katsmeow-afk flavor can be enjoyable
23:24 katsmeow-afk opening and closing the microwave, pushing buttons, supplying it electricity, all more complex than tossing bread onto the wood heater
23:24 genesis cooking should be a pleasure
23:25 furrywolf getting wood, cutting wood, building a fire, etc... :P
23:25 genesis OMG that's not food :(
23:25 katsmeow-afk the wood and fire is for heat, the side effect is great toast and scrambled eggs!
23:26 furrywolf I haven't built a fire in over a year...
23:27 katsmeow-afk me either, dogs won't would not me gather wood, and now all my chimney steel is lost with the move to Fla
23:28 furrywolf install some type of fence with enough spikes to impale any dog being tossed over it.
23:29 katsmeow-afk if the gods got hurt, they'd put me under the jail, i'd never see daylight again
23:33 furrywolf I re-wired my solar today and put in the 500A shunt for the trimetric in the ground line... didn't get a chance to wire up the actual meter, with helping move the blazer instead.
23:34 katsmeow-afk under what conditions will your panels put out 500 amps?
23:36 katsmeow-afk i made an ampmeter shunt once, it was ~8ft of paralleled #4 copper from the batteries to the motor
23:36 furrywolf they won't. it is, however, much easier to draw 500A off the batteries than to put 500A into them...
23:36 katsmeow-afk umm, yeas
23:36 furrywolf the current shunt is for the batteries, not just the solar input.
23:36 furrywolf when, say, a big motor kicks on, the shunt will have a few hundred amps running through it.
23:37 tsmeow-afk
23:37 furrywolf I can pull ~200A continuously pretty easily, with much higher peak.
23:38 katsmeow-afk why not arrange the batteries for 160vdc, and switcher an h-bridge to make 120vac directly, the current would be vastly lower
23:38 furrywolf because I use off-the-shelf parts, which are all 12, 24, or 48v.
23:38 furrywolf with the parts I have, 24v is the best option.
23:39 katsmeow-afk series the 12v parts to make 160, or tie each 12v to a separate bank in the stack
23:39 katsmeow-afk i was just wondering why people don't, because no one told me why they don't
23:39 katsmeow-afk some commercial sites do, of course
23:40 furrywolf the trimetric meter measures the voltage and current into or out of the batteries, and uses that to compute their percentage charge accurately, as well as other statistics.
23:40 katsmeow-afk they go for max reasonable voltage and then switcher it down to be useable
23:40 furrywolf so it uses a big shunt to monitor the current
23:43 furrywolf lower battery voltage is safer, can be used with smaller systems (14 u1s may have the same capacity as four golf cart batteries, but one is a lot easier to work with), fewer cells to check, can be charged with a much smaller solar array (rather than needing 504 cells in series), you can use standard power mosfets which usually have a 60V or 150V maximum rating rather than expensive bjts, legal issues with voltage and who's allowed to wor
23:44 katsmeow-afk ah
23:45 furrywolf battery equalization becomes more of a problem with increasing numbers of series cells, ul approval is required, you still need a transformer for isolation anyway, you still have to do a lot of work to make a sine wave anyway, failed cells cause a much bigger problem, more interconnects needed, ummm...
23:45 furrywolf I'm sure I can find more reasons, but I don't care enough. :)
23:46 furrywolf there's plenty of reasons 24v is bad too, mostly the amount of copper needed, the very low resistance allowable for all components, etc.
23:47 katsmeow-afk yeas, for the same losses as at 120v, the 24v system needs 1/5 the copper losses
23:47 furrywolf 1/25th, methinks...
23:47 furrywolf watts lost are i^2r, if you half the current, you can get away with four times the resistance.
23:47 katsmeow-afk for x watts, 24v is 5x the amps as 120v
23:48 katsmeow-afk it's close to midnite, and i got zero sleep last nite,, my body wants to sleep sittng, so i am awake in bed and keep falling alseep sitting up
23:49 katsmeow-afk i need a new body
23:49 rrywolf solves the problem by tucking katsmeow-afk snugly into bed, then curling up on top of
23:49 katsmeow-afk m, warm
23:50 furrywolf I'm tired too... got up around 6 today, and haven't stopped working until I finished re-parking my truck above. heh.
23:51 katsmeow-afk afk-er a few
23:51 furrywolf I'll probably head to bed pretty soon myself.
23:54 genesis so do i
23:54 genesis "nite :)
