01:29 rue_shop2 AHA! panasonic DT816 line card!
01:29 rue_shop2 just the 4 I needed
01:48 rue_shop2 circuit boards everywhere
01:55 rue_house I must remmeber to sternly avoid 820R smt resistors on my projects
01:55 rue_house 330R is ok, 220R is ok, lots of 100R
01:55 rue_house no 820
02:20 SleepersTide rue_house: you could put a 220R and six 100R resistors in series :P
02:25 rue_house well.,..
02:26 rue_house hit, error = 0.221729% vals = 1500.000000 and 1800.000000 at 818.181824
02:26 rue_house hit, error = 1.296296% vals = 1200.000000 and 2700.000000 at 830.769226
02:26 rue_house (parallel)
02:26 rue_house hit, error = 1.204819% vals = 560.000000 and 270.000000 at 830.000000 (series)
02:30 Jak_o_Shadows From what i'm seeing on the internet, if you chuck a motor onto a bit of cardboard, it'll fly, so I'm worrying too much about finding a good design
02:31 rue_house heh
02:32 Jak_o_Shadows I think I should remake my foam cutter. Put a proper tensioning system on, and make it so I can put some guides on
02:33 rue_house take the current off the wire before the spring
02:34 Jak_o_Shadows Yeah. It's more the physical mechanical aspects of it that i'm thinking about. The trick is, I want it to be collapsible
02:39 Jak_o_Shadows http://www.summerthunder.net/images/posts/Cutter01.JPG Hmph. Clever
02:39 rue_house http://www.ebay.ca/itm/1R-9999999R-Seven-Decade-Programmable-Resistor-Board-Step-1R-1-4W-SKU9715E-/161104887232
02:40 rue_house back in my day resistor decade boxes were huge and clunkey!
02:40 rue_house clever, sure, till it whips you in the face one day
02:41 Jak_o_Shadows Well, yeah.
02:41 rue_house remember to have a good ref fence and a 90 degree bracket
02:41 rue_house like a tablesaw
02:42 Jak_o_Shadows Yeah.
03:07 rue_house the internets not cool anymore, as with everything else, everyone jumped onboard and wrecked it, lets start a new one and call it something else.
03:07 rue_house :)
03:16 zap0 internet 2.0
03:16 zap0 start a BBS
03:17 rue_house yea, we can use the telephony network as a starter infastructure
03:17 zap0 you're probably confusing www with the internet.
03:17 rue_house no wait, lets wire directly house to house as we sign people up
03:17 zap0 wire? this isn't 19xx
03:17 rue_house hey wire works, rf dosn't
03:18 zap0 seems to work for interstellar rays
03:18 rue_house fiber works too
03:21 rue_house why are there no ~3A mosfets made in TO-92?
03:25 zap0 aliens!
03:27 rue_house ... and?
03:30 rue_house ok Im tired, but its 1am
03:30 Jak_o_Shadows right, cut the arms, drilled the holes for the tensioning system
03:30 Jak_o_Shadows I really oughta get a set square
03:32 Jak_o_Shadows I'm giving myself about 60cm workplace height.
03:45 rue_house what if you need 61cm?
04:02 Jak_o_Shadows I remake the upright. I have about 9m of it left.
04:02 Jak_o_Shadows Also, I have about 25cm on either side of the wire
05:08 GuShh_ rue_house: you could always join my outernet
05:08 GuShh_ it's like the internet, but everything happens outside of the box
05:09 GuShh_ that is to say, we couldn't afford server cases.
05:25 theBear now that's thinking outside of the box !
05:25 Shh_ hands theBear the
05:27 rgantuaSauce_ intercepts the transaction and shotguns the
05:27 eBear smiles theSmile with theM
05:34 GuShh_ http://www.mini-lathe.com/X3_mill/X3rvw/X3.htm
05:35 GuShh_ looks kinda rough built
05:42 Jak_o_Shadows ew, imperial everywhere
05:42 GuShh_ where where
05:42 Shh_ gets the
05:43 GuShh_ I think the x3 would cost two to three times more than a used, old benchtop mill... trying to figure out whether there's any advantage in it
05:43 GuShh_ replacing the bearings on the old machine is not too expensive, but it could turn out to be a swearing exercise.
05:46 GuShh_ the old one has a 3 phase 1hp motor, with a vfd... so I'm not even worried about speed control and I'm pretty sure it's going to have better low end torque than the threadmill motor they use on those siegs
05:46 GuShh_ treadmill, whatever.
05:51 GuShh_ theBear: beer for breakfast seems to work out fine, am I going through a downard spiral?
05:57 GargantuaSauce_ no way
05:57 GargantuaSauce_ it's liquid bread, man
05:57 GuShh_ in theory
05:57 Faek Depends what kind of beer i think
05:57 GargantuaSauce_ just don't neglect your daily bacon requirements
05:58 GuShh_ we aren't big in bacon here
05:58 GuShh_ even though a lot of us are italian
05:58 GuShh_ sure we cook with it, but it's not like in the US where you even have bacon icecream...
05:58 GuShh_ wonder if McD will ever introduce that one here
05:58 GuShh_ doubt it
05:59 GuShh_ is it any good?
05:59 GuShh_ I can actually enjoy real icecream instead of a mcflurry though, same price
05:59 GuShh_ and lots more options
05:59 GargantuaSauce_ i dont go to mcdicks so i have no answer to that one
06:26 theBear GuShh_, last few years i can't imagine bacon and eggs without it ! tho non greasy breakfasts i uusually prefer bloody maries complete with celery for health reasons
07:12 GuShh_ yey alignment tool is ready
07:12 GuShh_ the blackening came out much better than the first attempt
07:14 GuShh_ next time I would probably just tap the hole and use a bushing with a machined nut then flatten the bolt on the other side, remove, blacken, reassembly (I would also blacken the bolt) ... but enough of that, onto the next tool.
07:17 Shh_ wonders how to gunblue by
07:18 GuShh_ http://gushh.net/tmp/dscn4051f.jpg
07:20 GuShh_ small parts I get it... but big parts, without a controlled heat source...
07:25 GuShh_ and slow blueing doesn't look like blue to me
10:29 Curious y
11:25 rue_house GuShh_, is it steel?
11:32 KongfuPanda Hi GuShh_
11:35 MrCurious morning TuShh_
11:36 GuShh_ rue_house: the shaft? mild steel, polished and blackened (oil quench)
11:37 GuShh_ it's got a somewhat better finish than those carbide tools I got heh
11:37 rue_house whats the roller for?
11:38 GuShh_ aligning small parts
11:39 GuShh_ rue_house: here's a video of a similar tool, same idea https://www.youtube.com/watch?v=s0aNbxZj4qQ
11:40 GuShh_ seems the round shaft is a better idea to use with a mill as well, but considering how simple it is to make, I could always make another one.
11:43 rue_house oh I see
11:45 rue_house looks like it can save some twiddling time
11:45 rue_house yours if for lathe then yes?
11:46 GuShh_ yes
11:46 GuShh_ since I don't have a mill yet...
11:46 GuShh_ oh look it's MrCurious
11:46 rue_house I been thinking, XY tables aren't that expensive
11:46 GuShh_ converting a drill press?
11:46 KongfuPanda Hello GuShh_
11:47 GuShh_ doesn't really work
11:47 rue_house no
11:47 rue_house building a mill
11:47 GuShh_ you could get away with a big old one assuming it had a stiff quill, for alu.
11:47 ngfuPanda slaps GuShh_ across the
11:47 GuShh_ not sure I would want to build one either, but if it floats your boat :p
11:47 GuShh_ KongfuPanda: ouch
11:48 GuShh_ I'm trying to convince a dude to bring his mill over with his favourite truck company and I'll pay him cash at that point
11:48 GuShh_ but he won't budge, he wants me to pay him and get it at the warehouse in the middle of nowhere.
11:51 GuShh_ it's an OK deal if he adds a vise and accepts my offer, but there's the shipping and payment issue. why should I trust him at all, at least if he brings it with a friend or known company he won't be at any risk
11:51 GuShh_ if I go over there and pay him, I have no guarantee I will get the machine delivered.
11:51 GuShh_ and I don't want to waste time with that sort of thing either.
11:52 GuShh_ KongfuPanda: what's with the slapping anyway
11:52 GuShh_ rue_house: cnc bed type of mill or a bridgeport kind of mill?
11:52 KongfuPanda GuShh_, I said hello twice with no greeting..
11:52 GuShh_ hmm if you have a boring bar holder with a QCTP on the lathe, you should go for a round shaft
11:52 GuShh_ KongfuPanda: hello!
11:53 ngfuPanda gives GuShh_ a mu
11:53 GuShh_ but I figured square stock meant less fiddling around with it
11:53 KongfuPanda positive reinforcement
11:53 rue_house I cant work out how to raise and lower a XY table well, so probably more like a cnc
11:54 rue_house you got ideas?
11:54 GuShh_ you can move either the headstock or the entire xy table
11:54 GuShh_ moving it is not an issue, making it stiff enough would be an issue for me!
11:54 GargantuaSauce_ that's what she said?
11:54 rue_house big pipe, lots of welding
11:54 GuShh_ steel flexes a lot
11:55 GuShh_ the column type mills like the X3 have a shock absorber on the back to aid with the movement (or whatever you call them, "gas cylinder")
11:55 rue_house are you suggesting I make it out of wood? I stopped using wood on my projects a long time ago...
11:55 GuShh_ older may be preloaded with springs I guess
11:55 GuShh_ wood flexes even more!
11:55 rue_house :)
11:55 GuShh_ and changes even more with the weather heh
11:56 GuShh_ there's a reason cabinets require the center panels to be loose inside and not glued
11:56 GuShh_ expansion
11:56 GuShh_ rue_house: you live in a real country, maybe you could find a used mill for cheap
11:56 GuShh_ and then pimp it up
11:57 GuShh_ or use it as a starting point
11:57 rue_house dont have room for a real mill
11:57 rue_house but I have a lathe!
11:57 GuShh_ you seem to have a lot of space, I think you need to reorganize some stuff
11:57 rue_house which I have successfully done milling on
11:57 GuShh_ alright then for simple milling operations, look for a milling vise for the lathe
11:58 GuShh_ and if you already have one, and haven't got a need for a mill.. why are we even discussing this :p
11:58 GuShh_ rue_house: problem is you are limited to small parts
11:58 rue_house I was able ot use a wood carbide bit on steel, till I accidently tried to plungs
11:58 rue_house plunge
11:58 GuShh_ butcher!
11:59 rue_house it distributed the bit nicely around the shop
11:59 rue_house always be carefull how many turns out you were when comming back in!
12:00 rue_house 3...2... ARG!
12:00 GuShh_ hope this guy bends over to my demands already... I need this thing!
12:01 GuShh_ OK don't take that out of context GargantuaSauce_!
12:01 rgantuaSauce_ adds a few more lines to GuShH
12:01 rue_house I wonder if these $11 car amps are any good
12:01 GuShh_ the ones with usb in an extruded alu enclosure?
12:02 rue_house http://www.ebay.ca/itm/Digital-LED-12v-mp3-decoder-board-2-3w-Amplifier-FM-Radio-usb-TF-Remote-F-CAR-/281144149616
12:02 rue_house heh
12:02 rue_house "host my own images? why?"
12:03 GuShh_ he's offering the mill, vfd, 10 collets, collet holder... a few endmills, one indexable endmill, chuck, some drillbits (don't care for them but he mentioned them) and possibly the vise as well, but won't budge on the delivery and payment terms
12:03 GuShh_ all for half of what the X3 with no accessories would cost me
12:05 GuShh_ next up I'm going to bring up the fact that he's missing the original stand and the coolant pump, so I'm already paying way too much money for him not to budge.
12:06 Tom_itx doesn't mean he has to budge
12:06 GuShh_ I'm the buyer and I already stretched my price to very close of what he wanted, if he won't simply budge over delivering it himself then he probably doesn't really want to sell it
12:07 GuShh_ because he wants cash, and I'm not going to the middle of nowhere with that kind of money, not knowing the person at all.
12:10 Tom_itx rue_house, a mill with moveable xy table is a knee mill
12:11 Tom_itx ballscrew, acme screw underneath
12:13 Tom_itx carbide bits for wood are not center cutting sir
12:15 GuShh_ rue_house: http://www.mini-lathe.com/X3_mill/X3rvw/column3.jpg
12:19 GuShh_ Tom_itx: doesn't seem too fair that I have to budge to his demands and he won't budge to mine?, I'm already paying for the shipping it's not like I'm asking for him to bring it over at no extra cost either. My request seems reasonable enough...
12:20 GuShh_ Probably doesn't want to move his arse off the chair and that's why he refuses.
12:29 zero_coder hey
12:30 MrCurious GuShh_: ITS A TRAP!!!!
12:31 zero_coder has anyone tried robotics with rpi
12:31 zero_coder ?
12:31 MrCurious many have
12:31 MrCurious it works
12:31 MrCurious not well
12:31 MrCurious but it works :)
12:31 MrCurious sorry, my inner troll just escaped
12:32 zero_coder MrCurious, really?
12:32 zero_coder what is wrong with it?
12:32 zero_coder i mean with rpi
12:32 MrCurious my robot build uses a rpi to read t\e 10DOF sensor board, RTC and GPS
12:32 MrCurious it also acts as a wifi access point
12:32 MrCurious not enough io pins, and its a slow cpu
12:32 MrCurious beaglebone black has more io
12:33 MrCurious and is faster for only $10 more?
12:33 zero_coder okay.
12:33 zero_coder MrCurious, i am totally new to robotics and electronics as well
12:33 MrCurious odroid-u2 is 2ghz quad core for $85
12:33 zero_coder i want to buil my first one
12:33 zero_coder but the thing is I have got a pi already from somewhere else
12:33 MrCurious i am not a pro. i will talk, but seek others guidance as well
12:34 MrCurious you can use it. got an arduino?
12:34 zero_coder okay
12:34 MrCurious a motor driver and some motors
12:34 zero_coder so how do I get started?
12:34 MrCurious letsmakerobots.com
12:34 zero_coder nope.
12:34 zero_coder will I need one?
12:34 MrCurious read around that site some...
12:34 MrCurious google image search for robot and tune in on ones that look achievable
12:35 MrCurious hng out here and wait for a robot chat-storm to happen
12:35 zero_coder l2b or some IC , right?
12:35 MrCurious I2C
12:35 MrCurious ebay is a great source of cheap robot parts
12:35 zero_coder i want to make it for a robosoccer contest :)
12:35 GuShh_ zero_coder: https://www.youtube.com/watch?v=SGyOaCXr8Lw
12:35 zero_coder a 20X20X20 cm
12:36 zero_coder thts the dimension
12:36 MrCurious sunds lilke you want to crawl out your mama and fly right away, skipping that crawl, walk, run steps
12:36 GargantuaSauce_ start by blinking an led
12:37 MrCurious always a great start!
12:37 MrCurious discuss purchases here, often people here can point out cheaper alternatives, allowing you to get more bang for the buck
12:38 MrCurious you said socker robot...
12:38 MrCurious wheeled or bipedal...
12:38 MrCurious GargantuaSauce_: http://www.dhgate.com/product/dhgate/153877963.html?utm_source=pla&utm_medium=GMC&utm_campaign=fmt-model&utm_term=153877963&f=bm%7c153877963%7c102014-RemoteControlLine%7cGMC%7cAdwords%7cpla%7cfmt-model%7cUS%7c102014011-RCEngines-Parts-Accessories%7cc%7c&gclid=CNWI5ZGwgLkCFWNxQgodhnAA9Q
12:39 GargantuaSauce_ already ordered http://dx.com/p/193069 http://dx.com/p/193284
12:40 GargantuaSauce_ got 25 so can either do 4dof hex or 3dof oct
12:40 MrCurious ooking
12:40 MrCurious you paid more...
12:40 GargantuaSauce_ yeah like a dollar per
12:40 MrCurious did you order the 2 types of screws you will need
12:40 MrCurious i oversighted them first try
12:41 GargantuaSauce_ they are included
12:41 MrCurious right i see now
12:41 MrCurious nice
12:41 MrCurious cant wait to see what you end up doing with them
12:41 GargantuaSauce_ i am pretty stoked
12:41 GargantuaSauce_ 1.5 newton metres
12:41 MrCurious i bet
12:41 MrCurious i only have 8 of em, and i am stoked to get screws so i can make a crawling bot
12:41 GargantuaSauce_ going to need failsafes on the electronic/software side because otherwise it will be quite capable of injuring me
12:42 MrCurious yeah....
12:42 MrCurious they can really really pinch you
12:42 MrCurious may want to add in a current monitoring circuit
12:42 MrCurious to spot a sudden spike
12:42 GuShh_ MrCurious: another robot you won't finish?
12:42 GargantuaSauce_ better than not starting
12:42 MrCurious shush TuShh_
12:42 GuShh_ not really
12:42 zero_coder sorry i got disconnected last time
12:42 GuShh_ lol
12:43 zero_coder slow internet connectoin
12:43 MrCurious power button on the side is really starting to get annoying
12:43 GuShh_ MrCurious: !
12:43 zero_coder hey. u guys make robots for a living?
12:43 GuShh_ Hahahahahahaaaaaaaaaaaaaaaaaa
12:43 Shh_ r
12:43 MrCurious no
12:43 MrCurious live to make robots!
12:43 MrCurious the money is just a perk
12:44 GuShh_ you need to make a money making robot
12:44 MrCurious as is the limo's and helocopters and submarine rides
12:44 zero_coder ofcoz :) making is the coolest things
12:44 GuShh_ ...
12:44 zero_coder creation is the essence of existence :D
12:45 MrCurious do you have a "want to be a woman" complex?
12:45 zero_coder MrCurious, ?
12:45 MrCurious i am kidding
12:46 zero_coder MrCurious, i am on a kind of paranoia
12:46 MrCurious same as everyone here
12:47 zero_coder why paranoia?
12:47 MrCurious paranoia is an excellent urvival trait
12:47 MrCurious not an accident. evolution has reinforced it
12:47 zero_coder MrCurious, what do you do?
12:47 zero_coder :D
12:48 MrCurious why do you want to know. who sent you. why are you here. nobody home. *SLAM*
12:49 zero_coder :D :P
12:49 zero_coder i was just kiddin
12:50 zero_coder sorry
12:53 MrCurious :D
12:53 GuShh_ MrCurious: is zero_coder still on a youtube high?
12:54 MrCurious you will find GuShh_ to be an invauable robotic resource.. hardly anything robotic he doesnt know
12:54 zero_coder GuShh_, lol
12:54 zero_coder MrCurious, i will try to keep GuShh_ busy :)
12:54 GuShh_ MrCurious: you'll pay for that!
12:54 GuShh_ with cookies or icecream, or icecream with cookies.
12:55 zero_coder GuShh_, i have got an RPi
12:55 zero_coder and i want to get started :)
12:55 MrCurious icecream! you scream! we all scream!
12:55 GuShh_ ok, do as MrCurious says and blink some LEDs
12:55 GuShh_ quit watching youtube videos, you won't get there not even in a year.
12:56 zero_coder i cant even load youtube with my connection
12:56 zero_coder :)
12:56 MrCurious that was GargantuaSauce_
12:56 GuShh_ oh?
12:56 MrCurious i thought 2 months to make first bot. that was 2 years ago
12:56 MrCurious its a distracting mine field full of rabbit holes you can fall down into
12:57 GargantuaSauce_ https://www.youtube.com/watch?v=bj9gFFyR3-Y this took about a year of on-and-off messing around
12:57 zero_coder what kind of robots do you make?
12:58 GuShh_ the kind that go boop boop beep and blow up in your face
12:58 zero_coder :D
15:02 MrCurious domo arigato
15:37 mumptai hi
17:14 rue_house "PETEIE! what the hell are you doing?" "I'm practising throwing knives at Jimmy" "Ok.... WAIT! whats your plan if you miss?" "call 911" "ok"
17:21 MrCurious what is the first step in making a 300 foot tall biped robot?
17:23 rue_house get a good arc welder
17:23 rue_house like mine, a miller maxstar
17:23 rue_house 200 SD
17:26 MrCurious so a really big glue gun then
17:36 rue_house this is really interesting
17:36 rue_house http://www.ebay.ca/itm/Digital-LED-12v-mp3-decoder-board-2-3w-Amplifier-FM-Radio-usb-TF-Remote-F-CAR-/281144149616

17:37 rue_house how many different sellers do you think are really the same people?
17:38 GargantuaSauce_ probably not as many as there are sellers that are just doing dx drop shipments
17:39 rue_house they cant ship from north america
17:41 MrCurious dx drop shipment... seems like a scam
17:42 MrCurious undercut them by pennies, until they go away
17:42 rue_house you cannot ship from north america a $1 item and give free shipping
17:42 MrCurious probably run by nigerian royalty... they are very net savvy
17:49 GuShh_ so... I got a pretty cool idea to make a guide for the angle grinder to cut sheet metal perfectly straight... but there's a problem, I don't have a single bolt with the right size and pitch for the grip mounts on the friggin angle grinder... NOT A SINGLE ONE!
17:49 GuShh_ HOW CAN THIS BE
17:52 GuShh_ rue_house: that's a 3k tig welder, I don't think MrCurious would shell out that kind of money when he isn't even a welder
17:52 GuShh_ lol my cat is following what I type, I think shes spying!
17:53 GuShh_ rue_house: why do you use your tig strictly as an arc welder?
17:53 GuShh_ or do your tig welds look that bad? heh
17:53 Shh_ h
18:15 Tom_itx hi any42792780! welcome to #robotics
18:16 any42792780 hi
20:54 rue_house its not just a tig welder, its a tig/stick welders
20:54 Jak_o_Shadows Hot wire cutter upright is finished. Wire fits nicely down a groove in the aluminium extrusion I used, and the tensioning system (a spring) works
20:55 MrCurious any of you robot makers use twitter? i like following people who make cool shot...encourages motivation
20:56 Tom_itx twitter is for birds
20:56 rue_house hi kat
20:56 Tom_itx that like to tweet
20:56 Tom_itx it awakes!
20:56 m_itx feels a shift in the f
20:57 MrCurious that was me. got some gas... it will pass
21:20 GuShH rue_house: pretty much all tigs are capable of stick welding... irrelevant to the question though, why do you use stick instead of tig?
21:22 GuShH Jak_o_Shadows: why do you need a wire cutter?
21:23 GuShH well, why do you need to cut foams in general heh
21:23 R0b0t1 The last 20 times I have checked in here, GuShH has been on about welding
21:23 GuShH airfoils / wings and basic shapes for RC?
21:23 GuShH R0b0t1: and? welding is part of fabrication in the real world.
21:23 GuShH I was curious to know why he uses an expensive machine as if it were a 100 bucks unit
21:24 MrCurious1 gush does the non robotic part of robotics
21:24 GuShH Seems most of "robotics" involve plugging object A to object B and random fastening to already existing mounts, brackets and holes.
21:25 R0b0t1 Oh, I wasn't complaining
21:25 R0b0t1 It's just... that's a lot of talk about welding.
21:25 GuShH at least for the maker type of crowd, who in fact are not makers but buyers, consumers.
21:25 GuShH a lot?
21:25 Faek I think it's just that GuShH talks a lot
21:25 GuShH why don't you change the subject to something more interesting then
21:25 Faek Which isnt a bad thing of course
21:26 GuShH Hey I do as much as I talk!
21:26 ace4016 GuShH, heh, i've felt more or less teh same way bout the "maker crowd"
21:26 GuShH I was just prototyping a fence / guide mechanism for an angle grinder
21:27 R0b0t1 Oh yeah makers are makers, because you need tools for making
21:27 R0b0t1 Oh, angle grinder guide would be REALLY useful
21:27 GuShH as I'm not going to bend over and buy a plasma cutter after they increased the price 25% since I last got a quote.
21:27 Tom_itx some of them _are_ tools
21:27 GuShH ...and I need to cut 1mm thick sheet metal relatively straight, and my pulse sucks lately.
21:28 R0b0t1 Tom_itx: I would go ahead and say most, because they expect to exchange money for understanding
21:28 GuShH my shears won't clear both sides far enough to cut continously
21:28 R0b0t1 They also expect to get nice answers from books and/or just copy stuff
21:29 R0b0t1 GuShH, any hackerspaces nearby?
21:29 GuShH and the extra step of straightening the steel is annoying, however you get the added benefit of an actual stress cut vs grinding
21:29 R0b0t1 Sadly most the people in them call themselves "makers"...
21:29 GuShH R0b0t1: no and if there were you wouldn't find a cnc plasma cutter and if you were to find one it wouldn't be big enough to accomodate the 1x2 meter sheets
21:29 R0b0t1 The one where I used to live had multiple CNC machines
21:30 GuShH but it's OK, this is just OCD and me.
21:30 R0b0t1 I see
21:32 Jak_o_Shadows Yeah, cutting foam for RC and stuff
21:32 Jak_o_Shadows well, that's the plan anyway
21:32 Jak_o_Shadows Also may make some tabletop scenery and stuff.
21:36 GuShH hmm so they sell small mounts that will turn an angle grinder into a tiny chop saw, but no linear guides for straight cuts on sheet metal?
21:38 Nashenas Hi, can anyone recommend a good soldering iron for working on electronics? I ruined the one I have before I learned how to solder properly. The tip is covered in old solder and sponge material from the cleaning sponge it came with (I don't like how the sponges work, or I could be using it completely incorrectly).
21:39 GuShH you could get a new tip
21:39 Tom_itx weller
21:39 GuShH brand is irrelevant if he doesn't take care of it
21:39 Tom_itx get one with temp regulation
21:39 GuShH you can ruin a metcal in under 10 seconds if you're a monkey
21:40 GuShH Nashenas: the sponges are meant to be used wet
21:40 Faek If he isnt good at soldering get a cheap one
21:40 Nashenas ohhh, good ideas
21:40 GuShH replace the tip, learn how to use it, invest in a better one once you are competent with it.
21:41 GuShH as Tom_itx says Weller are a good starting point --- but anyway learn the basics first.
21:41 Nashenas GuShH: you just made me realize what that screw is there for...
21:42 GuShH yes it holds the tip in place, usually two screws... maybe one on newer cheaper models
21:42 Jak_o_Shadows Mine has a single hex screw
21:42 Tom_itx i went thru a RS iron in one day so it does make a difference
21:42 Tom_itx was hardly worth the $15 or whatever they charged
21:43 GargantuaSauce_ mine has a screw-on collar
21:43 GuShH I think the biggest issue with most people is they don't use enough flux! and this is an issue because cheap irons self regulate at a very high temperature which turns the flux in flux core solder into smoke rather quickly...
21:43 Tom_itx awww... flux it
21:43 GargantuaSauce_ you arent doing it right unless the room smells like a forest fire
21:43 MrCurious avoids the shorts luke!
21:44 GuShH these are not the 'roids you're looking for!
21:44 Nashenas I was using solder with flux in the core
21:44 Tom_itx what sort of flux?
21:44 GuShH yes but something tells me the flux is vaporizing before it can flux the joints
21:45 MrCurious does flux eat flesh?
21:45 GuShH Nashenas: you should make a video showing off your soldering technique
21:45 Nashenas Can't remember, and I can't find the roll of solder either. It was more than a year ago. Rose-core comes to mind, but not sure at all
21:45 GuShH rosin
21:45 GargantuaSauce_ not if it's rosin MrCurious
21:45 GargantuaSauce_ it just makes your fingers gross and sticky
21:45 GuShH some fluxes (for plumbing and brazing) are rather nasty
21:45 GargantuaSauce_ yeah those are really acidic
21:45 Nashenas It's simple, touch end of soldering iron to wire, then touch solder to other side
21:45 Tom_itx don't use acid core solder on electronics
21:46 Nashenas ... then touch iron to solder so it melts faster (I know what I did wrong now...)
21:46 Jak_o_Shadows I think that's all I have left. I must get more solder
21:46 GuShH iron to solder, out of the joint? that just gets rid of the flux
21:46 GuShH you flood the tip after you're done working, to protect it
21:46 Nashenas Iron to solder, next to the joint
21:46 Nashenas flood it?
21:47 GuShH load it up with solder and leave it there when you turn it off
21:47 Nashenas ohhh
21:47 Nashenas then why won't the tip get hot anymore? It has solder on it, but that solder won't melt
21:47 GuShH and don't leave it on, your iron will keep on going after you stop using it, since it's just a resistor in parallel to mains
21:47 GuShH because the surface is contaminated
21:47 Nashenas ohhh
21:47 Tom_itx because you probably screwed it up
21:48 GuShH why won't paint stick to my oily metal!
21:48 Nashenas Tom_itx: without a doubt :)
21:48 Jak_o_Shadows http://www.ebay.com.au/itm/Solder-Flux-Solder-Welding-Iron-Wire-Reel-Rosin-Core-0-8mm-100g-Tin-Lead-Line-/290968135961?pt=AU_B_I_Electrical_Test_Equipment&hash=item43bf0d6919 seem ok?
21:48 Jak_o_Shadows I could get thinner stuff I suppose.
21:48 GuShH yong chang long!
21:49 GargantuaSauce_ you probably want stuff that actually lists the alloy
21:49 GuShH I mostly use 0.8, depends on what you do though.
21:49 GuShH Jak_o_Shadows: that's 60/40?
21:49 Tom_itx Jak_o_Shadows, i use .062, .032 and .015" solder
21:49 Tom_itx as well as solder paste for oven soldering
21:50 Tom_itx that doesn't tell you the lead/tin mix
21:51 GuShH oh so that's what I found in your fridge! I thought you were keeping robocop's semen samples in there.
21:51 Tom_itx kester SN63 is what i use
21:51 Nashenas I hope they don't mess up that movie.
21:51 GuShH 63/37 is very friendly, give it a try Nashenas.
21:51 Tom_itx that and silkscreen mask
21:52 Nashenas GuShH: The one Tom_itx mentioned?
21:52 GuShH stay away from RoHS solder for now, or ever.
21:52 GuShH Nashenas: yes
21:52 GuShH Sn is tin.
21:53 Jak_o_Shadows ha, all I can find in the major local store is lead free
21:53 GuShH yeah not uncommon these days
21:53 GuShH I bet RoHS is one of the biggest scams out there.
21:53 Tom_itx not so easy to solder with especially if you're not good at it to begin with
21:54 GuShH Designed to further increase obsolescence, not save the planet.
21:54 Tom_itx tin whiskers
21:57 Nashenas Would this be too thick for simple electronics? http://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_2158178_-1
21:57 Nashenas The data sheet says it has a diameter of 0.050 (don't see units anywhere) and a core size of 50
21:58 GuShH says inches
21:59 GargantuaSauce_ that is super thin, you probably want something thicker to start
21:59 Nashenas Would that be good to work with as a beginner? The amount seems like I'd have enough for a lot of "learning" *cough* mistakes *cough*
21:59 GuShH heh
21:59 GuShH it's always a good idea to buy big spools
21:59 GargantuaSauce_ wait no i can't units, that'd do just fine
22:00 Nashenas ahh ok
22:00 Nashenas I was like wow... from that series of solder that's the second thickest lol
22:00 GuShH 0.032 is the .8mm stuff I mostly use when I drag solder, so I don't have to feed too much for too long.
22:01 GuShH .015 is the minimum you should get, I don't see a use in anything smaller, if you can find it
22:01 GuShH copper braid helps with your mistakes, or just plain desoldering / cleanup
22:02 GuShH sad thing is it doesn't last very long, at least the tiny spools don't...
22:02 GargantuaSauce_ yes get braid for sure
22:02 GargantuaSauce_ and maybe one of those cheapass solder suckers
22:02 Faek Copper braid is awesome
22:02 GargantuaSauce_ and liquid flux
22:02 ShH spits on an aspirin and hands it to GargantuaSauce_ ... prison
22:03 GargantuaSauce_ <_<
22:03 GuShH not kidding!
22:03 Nashenas lol
22:03 GuShH it does work.
22:03 GuShH you gotta be all macgyver in life man.
22:04 Nashenas what are the easiest desoldering tools to use as a beginner? I messed up plenty of times before
22:04 GuShH "heat and tap"
22:05 GuShH macgyver is so cool he can make you the next gen iphone with just a fingerprint scanner and a polished turd.
22:05 Tom_itx i use solder braid
22:05 GuShH Nashenas: while tapping does work, I recommend not doing it on your underwear, or over precious objects, or sideways causing shorts.
22:07 GuShH a solder sucker is good for big amounts of solder, the braid will give you a lot more control over what you remove and how you remove it though
22:07 GuShH if you have the money a vacuum operated one is ideal...
22:07 GargantuaSauce_ yeah i am considering getting one of those
22:07 GuShH or at least a heated sucker
22:07 GargantuaSauce_ but braid and suckers can both be obtained for a couple dollars so start with those
22:08 GuShH I've planned to build a vacuum one but I couldn't be arsed
22:08 GargantuaSauce_ i imagine it's pretty easy to tear up traces with the vacuum ones though
22:10 GuShH the idea was to hold a vacuum in an empty oxygen tank (what I had), the vacuum would be pulled by a fridge compressor, then a simple ball valve for "regulation" and a steel wool filter to catch the molten solder, but I never worked out the rest of it. should work if you have a solenoid valve and a foot or pulse switch on the "gun"
22:11 GuShH said compressor won't start up anymore until it warms up (unclear if it's gummed up or what) so I really didn't bother to build it. another problem was figuring out how to keep the oil inside, but again... didn't care to build it.
22:12 GuShH I figured however that the compressor wouldn't be able to produce a usable vacuum without a holding tank
22:12 GargantuaSauce_ you wouldnt really even need a real compressor would you, just a repurposed gear pump or something
22:12 GuShH said tank could be a thick glass or a propane canister, whatever...
22:13 GuShH GargantuaSauce_: it's what I had
22:13 Nashenas I'm looking at desoldering braids now, and I don't know what the difference is for one that says "pure Rosin" and the other says "No clean"
22:13 GargantuaSauce_ oh i thought pretty much every refrigeration pump was reciprocating
22:13 Nashenas the braids have to match up with the type of solder used?
22:13 GuShH I then turned it into a small, silent air compressor for the airbrush, but later on I acquired a "real" one
22:13 GuShH no
22:13 GargantuaSauce_ no, the braid has flux in it...get the rosin one
22:13 GargantuaSauce_ no-clean flux is not a thing
22:14 GuShH GargantuaSauce_: two major kinds of pumps
22:14 GargantuaSauce_ you'll want some isopropyl alcohol kicking around as well for cleaning, it's the solvent that's usually used
22:15 GuShH or as theBear would say, in case you're thirsty
22:16 GuShH I don't understand why the food grade alcohol they sell everywhere around here has denatonium in it... if it's food grade, it's meant to be consumed, thus they shouldn't be adding a bitter agent
22:16 GuShH (if you are an evil prankster get some pet deterrent, it's almost pure denatonium... add it to someone's drink!)
22:17 ShH has tried it on purpose and couldn't feel his tongue for a few minutes, couldn't taste a thing for the rest of the
22:18 Nashenas GargantuaSauce_: https://www.jameco.com/webapp/wcs/stores/servlet/Product_10001_10001_124126_-1
22:18 GargantuaSauce_ get the rosin one
22:24 Nashenas wow... I definitely need a completely new iron. There's no hope getting this tip out
22:25 Nashenas I tried taking out the screw... and it got tight... so I turned a little harder, and then it got loose
22:25 GuShH use the force
22:25 Nashenas I though, oh gee, it came out!
22:25 GuShH it's rusted
22:25 Nashenas no. I broke the screw in half...
22:25 MrCurious take the cource luke!
22:25 GuShH steel heat and oxygen... bad combination
22:25 GuShH it broke because it was rusted.
22:25 Nashenas yes...
22:25 GuShH and low grade steel..
22:25 Nashenas lol, time for a new iron!
22:25 Nashenas it was a radio shack soldering iron... nothing fancy here
22:25 ShH would drill and tap the
22:26 GuShH even better, I would take pleasure in drilling that piece of shit
22:26 Nashenas I think I would enjoy it lol, if only I had a drill
22:26 Nashenas with my luck the drill bit would break :D
22:26 GuShH and fly into your eye?
22:26 GuShH that's my kind of luck.
22:26 Nashenas yes :)
22:29 Nashenas what does RoHS mean?
22:30 Tom_itx heavy metal compliant
22:30 GargantuaSauce_ another thing not to bother with
22:31 Tom_itx Restriction Of Hazardous Substances
22:31 Tom_itx out of hand just like homeland security
22:35 Nashenas and for soldering iron specs, I'm seeing cUL listed and UL listed. What does that mean?
22:36 Tom_itx Underwriter Labratories
22:36 Tom_itx has tested it and approved it
22:36 Tom_itx non chinese shit
22:38 Nashenas cUL means chinese Underwriter Labratories?
22:38 Tom_itx i dunno
22:39 Nashenas ahhhh, It's Canadian
22:40 Tom_itx yep

23:29 GuShH Was I involved? heh
23:29 any81808554 i dunno who was
23:30 any81808554 someone went off to #freenode and dragged a ircop back in here who did the deed
23:30 GuShH well I for one didn't know you were online
23:30 GuShH did you move?
23:30 any81808554 no, but i tried
23:31 GuShH still a druggy riddled place with no law?
23:31 any81808554 that was 2 yrs ago
23:31 any81808554 yeas
23:31 GuShH so what, I remember things.
23:32 GuShH the house you built, the neighbour dogs (bastards), you couldn't get your mail... I was paying attention, I'm not 100% asshole.
23:32 any81808554 i made something else, all i got for feedback is "that's nice, what is it?" or somesuch
23:33 GuShH my eyes must be acting up, I center punched, sweared it was center... drilled, I was off center. had to start from scratch (making a simple tool for the lathe)
23:33 any81808554 use a transfer punch instead, and start with tiny bits
23:34 GuShH second time around I used a vise to hold the work though, 50/50 chance I would get it right eventually.
23:34 GuShH started at 3mm
23:34 GuShH I always "step drill" specially since my bits are junk
23:34 y81808554 dinks it with 1mm, then
23:34 GuShH bah I don't have such luxuries.
23:34 GuShH I could've used a center drill though
23:35 any81808554 the dink hasto be just big enough to hold the next bit's center
23:35 GuShH but the smallest one I have is 3.15mm or so
23:35 ShH thinks rake, negative, positive, blah blah blah <explode
23:35 any81808554 chuck the 3.15 in the lathe and a file in the toolholder, that will skinny it down
23:35 GuShH -_-
23:36 any81808554 well, if all else fails, it will
23:36 GuShH what fails is me, finishing the stand for the lathe, because of life in general.
23:36 GuShH but I'll get there dammit
23:37 any81808554 yeas, i got so peeved at a stand for a generator/waterpump combo, i cast the bloody table out of concrete
23:37 GuShH lol
23:37 any81808554 it was **REAL** steady, sturdy
23:38 any81808554 cast the hole thru the 6" top for bolting stuff down
23:38 any81808554 holes
23:38 GuShH I poured concrete inside the drill press column, seems to have dampened some vibrations
23:38 any81808554 i was goona do that to a hollow-frame lathe
23:39 GuShH Tom_itx claims it's going to rust through but it's been primed with the chinese equivalent of corroseal
23:39 any81808554 shirt happened tho, so i did something else
23:39 any81808554 might take 10 yrs, if it's a stock size, it may be worth changing it out every 10 years
23:40 GuShH my lathe is hollow frame... all chinese lathes are, I couldn't find an old used one that was both fully functional (no missing parts), affordable and lightweight enough not to destroy my floor.
23:40 GuShH seems you can't have that combination.
23:41 any81808554 well, an all aluminum lathe would be light, untill you make it sturdy by pouring in the concrete
23:41 GuShH I wanted to replace it with a hydraulic cylinder but who has one of those taking up space in a corner?
23:41 any81808554 me
23:41 ShH s
23:41 any81808554 you want to look at another url?
23:41 GuShH I bet you have more than one haha
23:41 GuShH "which size do you want?"
23:41 any81808554 i swear i'll give you one
23:42 GuShH I'll look at the url, do I also have to look at the contents, parse them, make actual sense of them, try to have a meaningful conversation about them and perhaps come to a useful conclusion?
23:42 GuShH I'm not good at that.
23:42 any81808554 if you wish
23:43 y81808554 upl
23:43 GuShH you should blue or blacken the finger. maybe just the tip
23:43 ShH runs away laug
23:43 any81808554 hmm?
23:44 y81808554 misses the
23:44 GuShH the robot finger of course
23:44 any81808554 ?
23:44 GuShH nevermind
23:45 any81808554 http://designerthinking.com/MyTekPlugins500.html <<== the most recent of a larger project that's still uploading
23:46 GuShH and you got no response previously?
23:46 any81808554 altho it's recent only as of last week, when i quit updating
23:46 any81808554 i got "nice" , that's it, totally
23:47 any81808554 you know of Tektronix TM500 mainframes? that fits into them
23:47 GuShH what's the plan for the first plugin?
23:47 GuShH I know of them, I can't own them because there are none in the market, or lack thereof in Argentina.
23:47 any81808554 a few psu for bench stuff, powered by laptop wallwarts and deskwarts
23:48 GuShH the laptop smps have short and overcurrent protection right?
23:48 GuShH also thermal protection in theory
23:48 any81808554 i am also making for the 7000 series scopes
23:48 any81808554 yeas, cept for the really cheapo ones
23:48 GuShH the ones with bolts and stuff inside to make them feel heavier? I would imagine
23:48 any81808554 i plan on adding all that's missing in the plugn, volt/current/watts limits, and meters
23:49 GuShH well, nuts actually.
23:49 any81808554 no, they are pretty light when s&h is free
23:50 GuShH any81808554: how do they originally connect to the mainframe? are the connectors readily available at all?
23:50 any81808554 anyhow, the point of making them is: there's no free plugins, Tek made almost no empty plugin frames, usefull plugins are too pricey to gut, and i could use a few bucks and a few plugins
23:50 any81808554 yeas
23:50 ShH always has issues with connec
23:51 any81808554 the rear is edge connectors, the 7K and the TM500 connectors are still made
23:51 GuShH oh so no problem there
23:51 any81808554 the pcb to go into the plugin, and then into the mainframe, is the connector
23:52 GuShH plenty of thermal dissipation on those alu extrusions
23:52 y81808554
23:52 any81808554 the rails are 1/8 (.125) thick
23:52 GuShH yeah I've dealt with edge connectors -- will you just tin them or plate them with something fancier?
23:53 any81808554 depends on who is paying
23:53 GuShH lol
23:53 any81808554 Tek gold-plated the connectors in the mainframe, most pcb houses can gold plate the pcb fingers too
23:54 any81808554 http://designerthinking.com/MyTekPlugins.html
23:54 any81808554 i figure i can make some servo testers, robot interfaces, wireless stuff, etc etc etc for robotics and avr stuff
23:55 any81808554 it's just a real handy formfactor
23:55 GuShH not sure how many people around here or in general own these mainframes though
23:55 GuShH but I bet you can find them easily on ebay
23:55 any81808554 for power the mainframe doesn't supply, i can plug in a laptop psu for anotehr 60watts or more
23:56 any81808554 i figure i can make the TM506 mainframes cheaper than i can buy on ebay, then i'll sell mine
23:56 ShH is getting all warm and fuzzy
23:57 any81808554 electronics pr0n gets to you, eh?
23:57 GuShH If you target the maker demographic, make sure you reserve a slot for some tupperware, so they can keep a sammich or their latest robot nearby.
23:58 any81808554 not a problem, thanks for the feedback!
23:58 GuShH Actually it's a great concept and if you can source all the parts, make everything to a standard that satisfies you and in turn make a profit...
23:59 any81808554 the TM506 is such a good form for plugging in certain equipment as you need it at the bench, but it's what was avaialable and markettable in the 1970's and 80's, there needs to be an upgrade
23:59 GuShH Then you'd have to be insane not to pursue this project
