00:39 rue_house cant get the *&^&$ plug out of the new tank
00:39 rue_house 100gal tank
00:39 rue_house shoudl give me an hour and a bit of heat
00:53 tsmeow-afk gr
00:54 e_house would growl along but he already finished wrestling with the plug for the
00:54 rue_house if I strip anymore metal off it, I'll have to weld a handle onto it to get it anywhere
00:54 rue_house hmm, I could weld a handle to it
00:55 rue_house a thick flatbar one I can hammer on
00:55 katsmeow-afk there's some 11,000u caps on ebay for $4 , if i choose to allocate $50 for caps (disregarding s&h), i get 12caps (38amps worth) at that ebay price, but if i use 2,200u caps from mouser, i get 50 caps (60 caps worth)
00:55 rue_house ELNA make 600F caps
00:55 rue_house dont know the prince
00:56 rue_house price
00:56 rue_house ...
00:56 katsmeow-afk er, (60amps worth)
00:56 rue_house 10mR
00:56 rue_house 2.5V
00:56 katsmeow-afk i want ripple amps thru them, at 60v
00:56 rue_house then I dont suggest a 600F cap
00:56 katsmeow-afk 56, to be exact, max
00:57 katsmeow-afk i have 1.5 Farads of capacitors, but at 10v - 16v
00:57 rue_house http://www.ebay.ca/itm/10-x-6-pin-DIP-IC-Sockets-Adaptor-Solder-/140698510253?pt=LH_DefaultDomain_0&hash=item20c248e3ad
00:57 rue_house feedback rating of 99.9% means my odds are pretty god of getting an item
00:58 katsmeow-afk only thing using DIP6 are optoisolators
00:58 rue_house the seller having the name hkiron-* means almost 0% of getting item
00:58 rue_house yea, its of some use, and only $1
00:58 katsmeow-afk but thaishopetc is a good name?
00:59 rue_house yes
00:59 rue_house doing really well with that one, by fluke
01:01 rue_house kat, would you like to see my plausable dollar items list?
01:01 rue_house sorta a shortlist of sorts
01:02 katsmeow-afk if it's long, email itto me
01:02 rue_house 7" reels take HOURS to play out at 1-7/8"/
01:02 tsmeow-afk is already asleep, just bottom feeding for electrolytics at 60+v of 2200u or
01:02 katsmeow-afk yeas
01:03 katsmeow-afk specially at 1/3 mil tape
01:03 rue_house I'm digitizing stuff for the meuseum
01:04 katsmeow-afk 7" of 3600ft is about 7hrs
01:04 katsmeow-afk use 1mil tape and 3 3/4 , it's more "standard"
01:04 katsmeow-afk 1mil is alot more sturdy
01:04 rue_house were looking thru tapes for logs made by a guy about 40 yeras ago
01:05 rue_house so I'm recording both sides in stereo, then splitting and adjusting speeds
01:05 rue_house the recordins use different speeds and stereo mixes
01:05 rue_house and directions
01:06 rue_house and vu levels
01:07 rue_house we have a team to listen to it all for content
01:07 rue_house I dont know if that gets me in or out of the hard bit
01:07 rue_house nothing like comming back to it flapping off
01:08 rue_house find out that I need to trim the last 2 hours off the recording
01:08 katsmeow-afk :-(
01:09 rue_house sony deck, TC-255
01:09 rue_house :) its a woodie
01:10 katsmeow-afk that number sounds familiar,, it have the sliding panels over the jacks/knobs?
01:10 rue_house "so let me get this right, the floor plates in your room were in bad shape, do you been gradually swapping them for other deck plates distributed around the ship????"
01:11 rue_house katsmeow-afk, yes
01:11 rue_house less the big lever ont he right side
01:11 tsmeow-afk
01:12 katsmeow-afk yep, Radio Shack made a clone of that one
01:12 rue_house heh
01:12 rue_house 'its not a sony!'
01:12 rue_house the schematics in the back of manuals were so educational
01:13 katsmeow-afk RS's didn't have the sliding panel, and it has 1/4 mic jacks, the Sony has 1/8 mic jacks
01:13 rue_house these are 1/8!
01:13 katsmeow-afk right
01:13 rue_house never noticed that
01:13 rue_house people must have been really pissed off about that
01:14 katsmeow-afk i didn't buy it because of that panle and those 1/8 jacks
01:14 rue_house $400 pricetag in its day?
01:14 katsmeow-afk i ended up with a Roberts (usa version of Akai) and a Dokorder ,,, and the deck i have now
01:15 katsmeow-afk yeas, Sony was pricey
01:15 rue_house I know of the name akai
01:15 rue_house I think thats the amp I fixed
01:15 katsmeow-afk so was Sansui, i still got the AU-7700 :-)
01:15 rue_house hey
01:15 katsmeow-afk no you didn't
01:15 rue_house you dont have a sony colour reel to reel video player about?
01:16 katsmeow-afk if it was, you'd remember it
01:16 rue_house we have video tapes we need converted
01:16 katsmeow-afk i have 2 open reel video decks upstairs right now
01:16 katsmeow-afk oh, wait
01:16 katsmeow-afk no, these are those biarsed cassettes
01:16 katsmeow-afk not open reels
01:16 rue_house the orig player is a sony EV-310
01:17 rue_house I have two but they are in BAD shape
01:17 rue_house I got the motor running and something else blew (in a bad way)
01:17 rue_house even if I get it feding tape I dont know how to adjust any video path electronics
01:18 katsmeow-afk follow the manual, with test tape
01:18 rue_house I dont know if the tapes work
01:18 rue_house dont ahve the manual
01:18 katsmeow-afk back then, they aere pretty much all custom made, there was no standards for setting one up
01:19 Jak_o_Shadows i've got an old sansui amp that i should fix, but the problem is one of the speakers it used has no surround
01:19 rue_house surround?
01:19 rue_house cover?
01:19 Jak_o_Shadows the little bit of rubber/plastic connecting the speaker cone to the speaker frame
01:19 rue_house aaah
01:20 rue_house you can get them redone if they are worth it
01:20 katsmeow-afk you can buy those replacement surrounds
01:20 katsmeow-afk not sure where anymore, bt i have bought them
01:20 rue_house its almost done!
01:20 rue_house almost done!
01:20 rue_house just another meter or so!
01:21 rue_house flap flap flap flap flap flap
01:22 rue_house I have like 5 more 7" reels :(
01:22 Jak_o_Shadows aye, you can, not sure it's worth it
01:22 rue_house I'll do them at 3-3/4"
01:23 katsmeow-afk you can put a optical wheel detector so the tape goes thru it, the scratch off the oxide 3ft from end (or add 3ft of clear leader), so when the led-transistor can see thru it, it hits the reverse (or stop) button
01:24 rue_house :) its on loan
01:24 rue_house I dont thin the meuseum would liek me modifying it
01:25 katsmeow-afk oh, no, they wouldn't unless you can remove it
01:25 rue_house hmm triac, ....
01:26 rue_house awe, I missed mrs weaver slaughtering the aliens
01:26 katsmeow-afk you don't own the original tape? and the extended version? and the directors cut versions?!?!?
01:27 rue_shop4 ooo shop lost a few degrees with the door open all day
01:27 rue_shop4 katsmeow-afk, no
01:28 rue_shop4 but I'm not concerned about missing it this time
01:28 katsmeow-afk sheesh, Mouser is beating ebay's rear on capacitor prices
01:28 rue_shop4 I vacuumed the shop floor
01:28 rue_shop4 it looks so clean I want to lick it
01:28 katsmeow-afk only one where ebay is winning is those 11000u caps, and i'd prefer more of smaller sizes
01:29 e_shop4 thinks about turning on a few more computers to warm up the
01:29 rue_shop4 11mF
01:30 katsmeow-afk the 11000u cap is rated 6.4 amps, the 2200u is rated 2.3 amps, and thing is, using 3x as many hits the qty discount faster, which makes them competitive
01:33 katsmeow-afk for the same $50 spent on 2200u vs 11,000u, is 60amps vs 38amps in ripple current capacity
01:34 katsmeow-afk and the 2200 are shorter
01:35 tsmeow-afk growls for not getting a reel of 63v big caps when they were give-away pr
01:36 home haha
01:36 home sucks to be you :D
01:37 katsmeow-afk at least i am not using a nukebox to try and melt aluminum
01:37 rue_shop4 heheeh
01:38 rue_shop4 ok I'm officially putzing around in my shop
01:38 home rue_shop4: I WANT A SHOP
01:38 home where get!?
01:38 rue_shop4 I'v come to beleive copius amounts of putzing are the only way to get anything done
01:39 rue_shop4 home, build one, I open sourced the design and started a howto
01:39 rue_shop4 !assit shop
01:39 rue_shop4 ..s....i....
01:39 tsmeow-afk putzed today, and got more area cleaned up out
01:39 rue_shop4 !assist shop
01:39 tobbor Possibly http://eds.dyndns.org/~ircjunk/shop
01:39 rue_shop4 home ^^^
01:40 rue_shop4 it was only ~$16000 finished
01:40 e_shop4 looks at a missing piece of
01:40 rue_shop4 well, almost finished
01:40 home rue_bed: I have a shed at our house
01:40 home at my parents house
01:41 rue_shop4 I should start ebaying off my junk boxes
01:41 home we keep storage and stuff there :/
01:41 rue_shop4 some of these have lots of cool stuff in them
01:41 rue_shop4 home, go look thru the image log
01:41 home I was thinking of turning the shed into a green house...for the winter :d
01:41 home rue_shop4: I did, its CRAZY
01:42 home I want my own shop :*(
01:42 home but am 17 XD with no money :D
01:43 rue_shop4 build a reprap, they sell for $2000
01:44 home LOL
01:44 ace4016 sounds like you need an odd end job
01:44 home I only have 2,556.61 in savings
01:44 home ace4016: I can get an odd end job, but I am extremely stupid.
01:45 home I would rather practice math...and increase my problem solving ability, and my ability to focus on tasks..
01:45 home Right now, I gotta test this RPI to do vision processing, fuck around with a Kinect, work on my website/blog, write up a bunch of tutorials, and etc
01:46 home do that sketch I did yesterday of a stupid horse.... do the dishes...clean the house
01:46 home fuck my life XD
01:46 ace4016 doesn't sound like a lot; just pace yoursefl
01:46 home there is a lot XD
01:46 home a lot
01:47 home I would like a 3d printer and a laser cutter though ( expensive..i know)
01:47 e_shop4 dials the jukebox to "was I thinking? I didn't noti
01:53 e_shop4 looks at 160 cubic feet of raw materials that was supposed to get reorganized this su
01:55 katsmeow-afk that's a lot of volume,, what happens if you mix it with a lil cement and pour it out into molds?
02:11 rue_shop4 I'd have about a cubic foot of some awefull alloy
02:16 katsmeow-afk zzzzzzz
02:42 rue_shop4 !time
02:42 tobbor My watch says its 12:32AM Mon Oct 08 2012
02:42 e_shop4 keeps bouncing off the walls put
02:59 rue_shop4 ok finished making 2 gearboxes
03:17 rue_shop4 erp, if the music stops I almost fall directly to sleep
03:17 e_shop4 is sure to keep the queue
03:50 rue_shop4 *music might be too loud* -> didn't notice I left the shop vac on
04:12 rue_shop4 !time
04:12 tobbor My watch says its 02:02AM Mon Oct 08 2012
04:12 rue_shop4 heh, thought tobbor was asleep there
04:12 rue_shop4 THATS late
04:13 rue_shop4 ah, to putz I dont have to think
04:13 rue_shop4 so I can putz while I'm sleeping
04:20 rue_shop4 it seems to be a good idea for me to turn everything over on a regular basis, keeps the garbage full, which helps in the pound-in pound-out balance
04:20 rue_shop4 a balanace my deck is currently having issue with
04:24 e_shop4 check the chair of doom after regreasing it by spinning o
04:51 e_shop4 stops spinning for a
04:51 rue_shop4 how does half the room keep spinning when I'm stopped...
05:33 rue_shop4 error: music stopped.
05:33 rue_shop4 alarm: not awake
05:33 rue_shop4 error: bad state, should be in bed, correcting.

08:55 SuperMiguel So if i want to build this guy: http://www.lynxmotion.com/images/hi-res/irnman4.jpg how can i calculate the needed torque, so i can get the servos i need?
09:41 SuperMiguel So if i want to build this guy: http://www.lynxmotion.com/images/hi-res/irnman4.jpg how can i calculate the needed torque, so i can get the servos i need?
09:41 theBear don't repeat yourself
09:50 tsmeow-afk suggests a basic physics lesson so we don't need to guess what loads you will be putting o
09:51 theBear i ain't giving a basic physics lesson
09:52 katsmeow-afk of course you don't *give* a course, you *charge* for it!
09:53 tsmeow-afk points out a useful robot might lift the bolt holding the battery in the car, or it might lift the battery, or it might lift the car, and the servo ratings will be diffe
09:53 SuperMiguel mmm
09:54 katsmeow-afk i almost don't care how smallthe robot is, 4 to 8 of them properly placed *could* lift a car if strong enough
09:55 SuperMiguel HS-5685HM would be good enough right?
09:55 theBear most people make those servo-bots just use whatever is cheap and never place any load
09:55 theBear or any real load anyway
09:55 SuperMiguel i think its more than what i need, but i just dont want to be short on torque
09:55 katsmeow-afk SuperMiguel, i am not going to guess which is best for your secret application
09:56 SuperMiguel secret??
09:56 katsmeow-afk i don't know it
09:56 theBear secret, as in you never told anybody
09:56 SuperMiguel katsmeow-afk: im not asking for a guess, im asking how do i calculate it?
09:56 theBear hehe, and the loop begins
09:56 SuperMiguel i said i want to build this: http://www.lynxmotion.com/images/hi-res/irnman4.jpg
09:56 katsmeow-afk you do notknow how to calculate leverages?
09:57 katsmeow-afk i also don't care what you build, it's how you use it that matters, just as bear
09:57 theBear yeah, it's how you use me that matters
09:57 katsmeow-afk if you are building "irnman4" , then use that is specified as "used to build irnman4"
09:58 SuperMiguel i just want it to walk
09:58 SuperMiguel the only load it will have it will be it self
10:01 SuperMiguel or how do people know which servo to get?
10:01 theBear refer to my previous statement for that answer
10:01 katsmeow-afk since it has no load, get the ones that fit
10:02 tsmeow-afk is thinking of break
10:04 SuperMiguel So the manufacturer recommends http://www.lynxmotion.com/images/html/build089.htm a 168 oz. in. but im not sure how accurate that is, basically in the past i have goten cheap servos that dont hold the weight of what im trying to lift and they just either get stuck or fall back
10:07 SuperMiguel So they recommend this guys: http://www.servocity.com/html/hs-5645mg_digital_torque.html which are rate at 168 oz. in at 6V but for close to the same price i could get http://www.servocity.com/html/hs-5685mh_servo.html which are 179 oz. in at 7.4V
10:09 katsmeow-afk a smart man once said "to increase your success rate, just increase your failure rate" , i once said "if you don't do it, it won't get done" , someone else said "a day in which you don't learn something is a day wasted", and Nike Shoes said "just do it"
10:10 theBear i think i gotta agree with nike on that one... i mean, it's a chaotic world in which we live
10:11 katsmeow-afk so you wanna know how a baby servo in a do-nothing robot will or won't work? build it, study it, learn from it
10:12 katsmeow-afk wanna know what i say when something i build/repair goes up in smoke? i say "now i know that does not work"
10:13 SuperMiguel katsmeow-afk: the problem is that those servos will cost me about $700 dont want to buy the wrong ones :(
10:13 katsmeow-afk then also buy ones that fit your budget
10:13 theBear erm, if that many servos cost $700, you buyin the wrong servos
10:14 katsmeow-afk 20 servos?
10:14 katsmeow-afk prolly get them all on ebay for $50
10:15 katsmeow-afk certainly under $100
10:15 SuperMiguel well i need around 20 servos total and each is around $30
10:16 katsmeow-afk you should buy the stronger servos only if you want it to DO something, all you want is for it to walk, you could leave out all the arm servos unless it walks on those
10:16 katsmeow-afk bear, we should put up a pic like that and say he needs $100 servos, and sell them to him
10:17 SuperMiguel katsmeow-afk: well eventually i want it to move the arms, to grab something not heavy
10:17 katsmeow-afk because he'd buy hem, <reference to some smart guy saying something about being born every minute and stuff>
10:17 katsmeow-afk then build it with servos not strong, sheesh
10:19 home lol
10:19 katsmeow-afk are you going to buy the brackets and controllers from someone for that robot? then you bettter buy what they tell you to buy or stuff won't fit, and you don't seem like someone whoc an make your own mounting brackets
10:19 SuperMiguel :(
10:20 home I can't make my own mounting brackets
10:20 home SuperMiguel: he is just being an elitist, its okay
10:20 home SuperMiguel: just get others to make your shit for you
10:20 theBear katsmeow-afk, yeah, looks like he would
10:20 home SuperMiguel: leave the hard work to the hardworkers..
10:21 katsmeow-afk no, you got it wrong on 2 accounts: building a simple bracket is a basic skill, and i am a She, not a He
10:21 theBear AND we ain't gonna do the 'work' so some monkey can 'build' a robot
10:22 katsmeow-afk unless we "hard worker elitists" can sell you 10 cent brackets for $5 each
10:22 katsmeow-afk because apparently someone is going to sell you $5 servos for $30 each
10:24 SuperMiguel katsmeow-afk: cant really find a servo the same size, and 168 in .oz for $5
10:24 katsmeow-afk heck, for $50 i can have a 160ft-lb servo, and that's enough to lift a big car battery at arm's length
10:24 katsmeow-afk SuperMiguel, does the robot weigh 10lbs?
10:25 tsmeow-afk gives up on this conversation because bear and i already said all we
10:26 katsmeow-afk you don't have the skills to built it anyhow, or to redesign it, or to figure out how to do either
10:36 SuperMiguel katsmeow-afk: yes it does weight 10lb
12:42 IndianaRonaldo anybody have subscription for this journal?
12:42 IndianaRonaldo https://www.aiaa.org/JournalDetail.aspx?id=3436
12:43 rue_house I pulled a good one while asleep last night
12:43 theBear hehehe
12:43 rue_house I reassembled th charger for buddy
12:43 Tom_itx not much sleep ehh?
12:43 rue_house remembered everything but to set the li-ion cell voltage back to 4.2 from 12.6
12:44 rue_house so one cell is REALLLY bloated right now
13:07 rue_house they did it on 4 joints, used servos as turntables
13:07 rue_house everything else they knew to support it
13:07 rue_house !time
13:07 tobbor My watch says its 10:57AM Mon Oct 08 2012
14:13 katsmeow-afk you should drill a hole in the bloated cell to let the excess electrons flow out
14:22 CoJaBo katsmeow-afk: As a bonus, it will then double as a rocket =D
14:26 katsmeow-afk yeas, it may be interesting for a while
14:30 katsmeow-afk one day my stepfather used a wall in the house as a fireworks generator
14:31 katsmeow-afk not the wall so much, but the wiring in it
14:31 CoJaBo o_O
14:31 katsmeow-afk touched off with the drill
14:31 CoJaBo I saw a line transformer at a substation blow one time. That put on a nice show
14:32 katsmeow-afk i recall my thought on seeing the event were "oh that's interesting, he's done it again"
14:32 CoJaBo Very. Very. Very loud buzz.
14:32 CoJaBo I was right across the street too lol
14:48 elkng "and Psychology" thats because of turning people into robots ?
14:51 katsmeow-afk that is not the definition of "psychology"
14:55 rue_shop4 Psychology is helping them thru the mental part afterwords
15:15 katsmeow-afk i thought psychology was treating those Ai researchers who make supersmart bots, and get cursed, made fun of, spat on by the humans
15:20 rue_house nothing is a one-trick pony
15:21 katsmeow-afk 2 tricks or no tricks, eh?
15:28 tsmeow-afk ponders the situation whereby the box containing the 3kw (30a@115vac 60hz) convertor ,, the box itself weighs more than all the electrical/electronics in the box comb
15:30 katsmeow-afk and if i buy the box instead of making it, the box (made in usa and shipped in usa) costs more than all the electrical/electronics in the box combined
15:31 katsmeow-afk speaking of boxes, rue, do you need a 200amp transfer box?
15:36 rue_house katsmeow-afk, already have one, 200A automatic
15:36 rue_house 3 phase I think
15:36 rue_house its in the basement
15:37 katsmeow-afk well, i have 2, thought i'd share,, Tom, how about you?
16:08 rue_shop4 [me is asleep]
16:51 rue_shop4 katsmeow-afk, could you ask tigger aoutsomething
16:52 rue_shop4 part of the trick to making high capacity energy storage systems is hyperinsulators, but I'v never heard mention of them has tigger?
16:52 katsmeow-afk i can look it up manually
16:53 rue_shop4 there are superconductors, but I'v not heard of superinsulators
16:53 rue_shop4 super/hyper, whatever
16:53 katsmeow-afk not a trick, it's more like growing the insulating oxide on the plates after they are wound
16:55 ShH_Lappy wonders how much to charge for fixing someone's
17:08 katsmeow-afk depends on the cost of the transportation to get them to where their gps says they are
17:29 GuShH_Lappy katsmeow-afk: they bring it and they pick it up, I'm not a delivery boy!
17:32 e_mohr pulls the knob off the KBM sw

19:03 katsmeow-afk suspicios link, not opening
19:11 rue_house I bought two knobs from ebay
19:11 rue_house I want to hook them up to encoders and make them change numbers on 7 segment leds
19:12 katsmeow-afk ok
19:12 rue_house oh but I wanted to etch pcb's for buddy too
19:13 katsmeow-afk while they are etching, you wire up the switches
19:13 katsmeow-afk it's called multitasking
