00:00 MrCurious like looking at pwm
00:00 orlock this one was $200 second hand.. ebay the yare $5k+ second hand
00:00 GuShh_Lap WinME
00:00 GuShh_Lap 'nuf said.
00:00 orlock new model with same specs.. $13k
00:00 GuShh_Lap moving on
00:00 GuShh_Lap haha
00:00 MrCurious ok, your scope-penis is bigger than mine
00:01 MrCurious but mine still has new scope smell
00:01 orlock GuShh_Lap: 4ch, 1Ghz!
00:01 MrCurious 2ch 20 mhz!
00:01 MrCurious everybody limbo!
00:02 GuShh_Lap orlock: 1 per channel or just in single channel mode
00:02 GuShh_Lap you can buy "new smell" in spray form.
00:02 Shh_Lap slaps MrCur
00:02 orlock GuShh_Lap: per channel , but not sure. 5Gs/s
00:03 GuShh_Lap I think it probably muxes at some point
00:03 GuShh_Lap maybe with all 4 channels
00:03 orlock MrCurious: Thats about the specs of my other scope.. Tek 475
00:03 GuShh_Lap but maybe not!
00:03 MrCurious and what do you have that you need to look at in that resolution
00:03 Shh_Lap eyer
00:03 GuShh_Lap ok back to sleep.
00:03 orlock GuShh_Lap: its a very very high end Tek scope, colour coded probes and the works
00:03 MrCurious its cheap, $70, or about $4M argentinian reals
00:03 GuShh_Lap all digitals are color coded sir
00:03 MrCurious its throw away cheap
00:04 GuShh_Lap MrCurious: hey fuck you those are brazilian
00:04 MrCurious true, they do have real currency
00:04 orlock MrCurious: Nothing.. it was cheap, i intend to sell for profit
00:04 GuShh_Lap 70 usd is 560 ARs what I make when I fart.
00:04 GuShh_Lap MrCurious: admit it shit don't cut straight!
00:04 Shh_Lap g
00:04 GuShh_Lap haha
00:05 GuShh_Lap I'm such an ass, but it's all in good sport.
00:05 MrCurious you are!
00:05 GuShh_Lap yes! but I don't mean it.
00:05 Shh_Lap
00:05 MrCurious raise your hand if you have ever gone #2 at work, and calculated how much your #2 got paid....
00:05 GuShh_Lap http://www.cybergorillas.com/wp-content/uploads/2012/11/Mike-Tyson-Now-Kith.jpg
00:06 MrCurious nm, you dont have to raise your hand, its universal
00:09 rue_more hmm
00:09 rue_more at 20Mhz an avr can push 8 bit pwm at 78Khz
00:09 rue_more that should work for 8khz audio,
00:09 rue_more use a...
00:10 rue_more 19Khz low pass
00:12 Shh_Lap b
00:16 e_more runs GuShh_Laps burp thru a low pass to observe the audio qua
00:37 MrCurious i do not know what to make of this... https://www.youtube.com/watch?v=xBGP2tLtLtw
00:43 GargantuaSauce *zip*
01:44 rue_bed that there are youtube videos where the preceeding ad is better
02:03 Loshki MrCurious: you've led a sheltered life. Watch some RuPaul for homework...
04:22 Loshki OMG, I've killed it...
04:43 GargantuaSauce https://www.youtube.com/watch?v=-JDAUVyp1m8
08:52 rue_more GargantuaSauce, wrong data types?
09:28 rue_more looks like a signed/unsigned mismatch
13:25 zennist Hey I have an idea of using really small servos & foldable robotic arms at the back of my smartphone. So normally the arms would be folded but you can drop the phone and it detects the falling and automatically de-fold the arms to extend into a robot
13:25 zennist Then you can control it via voice command
13:32 Hyratel yeah... great... if you'd stick around long enough for a reply
13:38 Tom_itx didn't wanna talk to him anyway
13:45 Skwint good to see the modern worlds lust for robotics bringing such vital advancements in medicine ... http://www.iflscience.com/technology/automatic-sperm-extractor-introduced-chinese-hospital
13:46 password2 lol
13:55 Tom_itx they coulduv dressed it up a bit better
13:55 Hyratel WHEEEE, big batch of Vishay samples arrived :D two types of MOSFETs, and Red, Orange and Yellow superbright LEDs
13:55 Hyratel Tom_itx, could've
14:45 MrCurious poor england.... http://i.imgur.com/EZu8xui.jpg
14:52 MrCurious they should make Suarez play next few years of games wearing this http://i.dailymail.co.uk/i/pix/2013/04/22/article-2312577-196CF2FB000005DC-608_634x510.jpg
15:40 deshipu hmm, the link from the topic doesn't work :(
15:59 Tom_itx woops
15:59 Tom_itx try http://tom-itx.no-ip.biz:81/~webpage/index.php
16:05 deshipu Tom_itx: thanks, that's better
16:05 deshipu I wasn't sure if it's the right place to talk about hobby projects
16:12 Skwint well, I don't think there's a better palce
16:12 Skwint but ... oh I dunno - try - if someone thinks its kinda cool they'll talk back :)
17:14 Hyratel http://kerbaldevteam.tumblr.com/post/89898082279/grab-ksp-as-a-steam-summer-sale-daily-deal-for-40-off
21:25 MrCurious GuShH: you get a fish. the band saw blade bounced on the rod, and barely scratched it
21:25 MrCurious the angle grinder ate through it in about 2 minutes
21:27 GuShH fish?
21:28 GuShH MrCurious: I was just being realistic and giving you a headsup, don't want to win any contests...
21:28 GuShH just get a really good american saw blade for it.
21:28 MrCurious now i suspect there may be a class on angle grinders i shouldl have taken
21:28 GuShH however after a certain hardness it's best to use abrassive cut
21:28 MrCurious as the angle grinder made a few plays for my forehead
21:29 GuShH keep cutting within the center line
21:29 GuShH otherwise it jumps up, or down
21:29 MrCurious i think next time, 80" cut from one side, then last 20 from other side
21:29 GuShH similar to a chainsaw!
21:29 GuShH kickback sucks.
21:29 MrCurious the vise on the band saw was great for holding the rod
21:31 Tom_itx MrCurious, you're not supposed to let go of the grinder
21:31 GuShH haha
21:31 MrCurious 2 hands
21:31 MrCurious just a bit surprising when it suddenly gets much bigger
21:31 MrCurious i mean closer
21:31 Tom_itx i love my little 4 1/2" grinder
21:31 ShH goes one handed with no guard, while having a dr
21:31 GuShH not really, don't be stupid with angle grinders!
21:31 MrCurious yeah, its a cheap harbor freight 4.5" grinder
21:31 MrCurious great for light shows
21:32 Tom_itx try it on some TI
21:32 Tom_itx for a real show
21:32 GuShH and inconel?
21:33 GuShH somehow those two should never meet, in what scenario do you take an angle grinder to inconel?
21:34 MrCurious wonder if magnesium is too soft to angle grind
21:36 GuShH now that will put a show.
21:36 GuShH one you may never stop.
21:36 MrCurious yeah, no off switch on that one
21:37 Tom_itx oh just douse it with water
21:37 Tom_itx :)
21:37 MrCurious i just worked out my optical temp guage may be of great use when angle grinding hardened steel to answer that priceless question
21:37 MrCurious is it too hot to pick up yet?
21:39 GargantuaSauce ya IR thermometers are super useful
21:39 Tom_itx problem with wearing gloves for grinding or welding is after the leather gets really hot it takes longer to get em off
21:40 Tom_itx then there's the slag in the boot trick...
21:41 Tom_itx MrCurious, if your glove smokes when you try to pick it up it's probably too hot still
21:41 Tom_itx no need for fancy tools there...
21:41 MrCurious i am going to write that trick down
21:42 MrCurious when working with hot glue, the answer always is "yes it is"
21:42 Tom_itx yeah and it's sticky too
21:43 MrCurious nalpalm of the rapid prototyping world
21:43 Tom_itx it's too hot when you can smell flesh before you feel the pain
21:44 GargantuaSauce yeah the worst is when you cant tell if you're pulling off glue or skin
21:45 Tom_itx you know those reprappers have gotten into it a time or two...
21:45 Tom_itx i bet they wouldn't admit it
21:47 GargantuaSauce i've definitely gotten a couple blisters from brushing the hot end
21:51 GuShH Tom_itx: leather gloves + welding + wet = bad
21:51 GuShH ask me how I know!
21:51 GargantuaSauce the water will conduct heat straight through the gloves i take it?
21:51 GuShH steam!
21:51 GargantuaSauce steamed hands
21:51 GargantuaSauce delicious
21:51 GuShH terrible.
22:27 MrCurious both rods cut
22:27 MrCurious only minimal hair burning smell
22:29 MrCurious tomorrow i can table saw the aluminum supports
22:38 MrCurious ir thermometer said the cutoff was 112F
22:38 MrCurious i think thats scientific for dont touch this
22:46 GuShH make sure it's not a bright surface though heh
22:47 GuShH MrCurious: after some time you get the habit of barely touching something to "probe" it.
22:47 GuShH it would be nice if we could see IR
22:47 GuShH but, on demand.
22:48 MrCurious i just know better to walk away, have a smoke, and come back befoore getting all touchy feely
22:49 GuShH MrCurious: we won another match... those guys were not playing nice.
22:49 GuShH how's your country doing
22:51 GuShH we play against switzerland next... we'll win.
22:51 GuShH 2-0 my guess.
22:52 GargantuaSauce i thought you quit!
22:52 GuShH they have 6 points, we have 9... could be 2-1
22:52 GuShH GargantuaSauce: it's MrCurious' fault.
22:52 GuShH I don't like the sport, I like numbers though.
22:53 GuShH USA needs to pick up, only 4 points.
22:53 GuShH Damn Russia sucks.
22:53 GuShH robotustra_: russia sucks.
22:54 MrCurious how is my country doing? i will tell you how its doing.... so poorly that the children of latin america are migrating to USA out of pity to help us out in future world cups
22:54 GuShH Algeria will get 1-0 against Russia.
22:54 MrCurious argentina was a good game, and no one got bitten!
22:54 GuShH hahaha
22:54 GuShH Yeah, about that...
22:54 GuShH The hell.
22:54 GuShH Feed the players before every match, problem solved.
22:55 GuShH If I know corruption well enough, Brazil wins the cup.
22:55 GuShH MrCurious: but don't worry, Australia is doing way worse.
22:57 ShH chuckles at Eng
22:57 GuShH Japan should just give up, they're good with robots, but that's about it.
23:18 MrCurious who is playing tomorrow?
23:18 MrCurious so england needs to win by what 5 or 6 points to stay in?
23:19 MrCurious japan kept getting it to the box, then stalling until every defender could get there to block them
23:24 GuShH MrCurious: spain has "the most passes" lol
23:24 GuShH lousy statistics, who cares.
23:34 MrCurious us:germany
23:34 MrCurious korea:belgium
