00:40 wildmage i need to figure out how to build a reaction wheel
00:41 Triffid_Hunter wildmage: reaction wheels are crap compared to control moment gyroscopes
00:51 rue_shop2 `it works! it works great!
00:51 rue_shop2 (knock sequence detection)
00:52 rue_shop2 wildmage, you could make one of those
00:54 rue_shop2 hahah getting up takes a LOT of energy
00:55 rue_shop2 ok, knock seqence detection in 996 bytes
00:55 rue_shop2 sweeet
00:55 rue_shop2 (that fits on a t13 ;) )
01:26 wildmage Triffid_Hunter, gyros are probably more difficult to build and more expensive
01:29 wildmage so is the difference between a CMG and a reaction wheel just that one is high inertia/low speed and the other is low inertia/high speed
01:30 wildmage i think i need to understand the physics of these things better
01:30 rue_shop2 build, play
01:30 rue_shop2 not many have the ability to
01:31 rue_shop2 I want to know how the math works to determine the rpm to get to in order to flip up
01:31 wildmage it's angular momentum
01:31 wildmage so you get an angular velocity alpha
01:31 wildmage and the angular inertia I
01:32 wildmage L = w * I
01:32 wildmage w is angular velocity
01:32 wildmage I is inertia
01:32 wildmage L is the angular momentum
01:33 rue_shop2 and Ff is part of what you say while trying to get the damned thing to work in the real world
01:33 rue_shop2 :)
01:33 rue_shop2 the math only gets you close
01:33 wildmage so the amount of torque is determined by how quickly you break
01:33 rue_shop2 indeed
01:34 rue_shop2 but you have to get the speed up enough to do it
01:34 wildmage since the torque T = dL / dt
01:34 wildmage so if you want 1s of torque, you ensure you break over 1s period of time
01:35 wildmage the magnitude of the torque is distributed over that time, a function of the total angular momentum
01:35 rue_shop2 so they just need to have enough speed to stop for 1s
01:35 wildmage well, you can have a weak brake.... gives you lots of time, but low torque
01:35 wildmage or you can have a strong brake, high torque but short time
01:35 rue_shop2 a particular deacceleration for a given time frame?
01:36 wildmage yes, depending on the maneuver you're trying to do
01:36 wildmage maybe just want kick in the pants is all you need, so just throw a monkey wrench in the gears and that will make it stop near instantaneously, causing it have a huge torque and make it go flying across the table
01:38 wildmage here's an example with a different system: http://www.youtube.com/watch?v=6aZbJS6LZbs
01:39 wildmage they use the instantaneous brake method
01:47 Fiesta i wonder if it's recouping that energy as it brakes
01:47 Fiesta the Cubli that is
01:48 wildmage it's converting that momentum into potential energy against the earth's gravitational field
01:48 wildmage so, it can reclaim that energy by just falling over
01:48 Fiesta coz it seems a shame to just kill that movement with friction
01:48 wildmage it becomes an inverse pendulum problem
01:49 Fiesta better to recharge the battery
01:49 wildmage it could be done, but it would be tricky to use braking as a control device and as a battery recharge method at the same time
01:50 Triffid_Hunter wildmage: the main difference is that the CMG is like 10,000% more efficient in terms of torque per watt
01:50 Fiesta nah
01:50 wildmage they both require different energy discharge profiles
01:50 Triffid_Hunter it is a little more mechanically complex, but the efficiency gain is well worth it
01:50 wildmage Triffid_Hunter, do you understand the physics?
01:51 wildmage i will have to dust off my dynamics book
01:51 Fiesta i smell pretension
01:51 wildmage Fiesta, not a fluid mechanics problem
01:53 wildmage Triffid_Hunter, where does the efficiency come from? I'm not seeing it
01:53 wildmage Triffid_Hunter, more efficient to rotate large mass slow than rotating small mass fast?
01:54 Fiesta here's a multirotor system that impliments braking on it's rotors, recoups the energy https://www.youtube.com/watch?v=to7aj6kRFJw&list=FLlHITiT7I1lYiFn6kd_RlBA&index=9
01:54 wildmage Triffid_Hunter, i can see how that would have less energy loss from kinetic friction
01:55 Triffid_Hunter wildmage: CMG uses precession instead of direct newtonian reaction which gives an output torque which is proportional to product of input torque and angular momentum of gyro, whereas reaction wheel gives output torque equal to input torque
01:55 Triffid_Hunter since angular momentum is conserved, the CMG can trivially amplify the input torque by tens or even hundreds of times for little to no extra power
01:56 Triffid_Hunter ergo, CMG is tens to hundreds of times more efficient than a reaction wheel, for the cost of only slightly increased mechanical complexity
01:57 rue_shop2 yay! I can train it!
01:57 wildmage Fiesta, neat... but can the battery withstand that kind of charge cycle profile for long? I know that batteries require a certain a current profile to keep them from going bad too soon
01:58 Fiesta i'd be charging it into caps, not the battery
01:58 wildmage Triffid_Hunter, thanks
01:58 Fiesta but the energy in those caps coudl then be shoved into the battery i guess, at your own pace.
01:59 rue_shop2 this is sweet, I can lightly tap out something on the desk and it reacts to it
01:59 wildmage rue_shop2, what have you done!?
01:59 wildmage you're not supposed to teach them!
02:00 wildmage quick! disconnect the power and erase it's memory before it teaches the others
02:00 rue_shop2 its a knock sequence detector
02:02 wildmage you mean percussive communication?
02:02 rue_shop2 its sequence recognition
02:03 rue_shop2 funny enough tho, its not able to detect MY FINGER ON THE PUSHBUTTON SWITCH TO MAKE IT LEARN THE SEQUENCE
02:03 rue_shop2 }:|
02:05 rue_shop2 oh, hehe, broken jumper cable
02:08 rue_shop2 this bench is starting to overflow with cool working projects
02:08 rue_shop2 a PD servo (encoder and step/dir inputs)
02:08 rue_shop2 a joystick to two hobby servo controller (using a tiny13)
02:08 rue_shop2 and this knock sensor
02:13 Triffid_Hunter need PID if you want it to hold position against a load
02:14 rue_shop2 Integrators are givign me grief
02:14 rue_shop2 i cant keep them under control
02:14 rue_shop2 they keep oscillating
02:15 rue_shop2 (slow, hunting)
02:15 rue_shop2 I tried some various reset mechanisms, didn't make much of a diff)
02:15 rue_shop2 ... oh no, I closed a brace I didn't start, what do I do now???
02:15 rue_shop2 oh I know
02:15 rue_shop2 :-|
02:16 rue_shop2 ok 948 bytes...
02:18 rue_shop2 I can dial a t13 up to 4.8Mhz, I wonder if thats enough
02:25 rue_shop2 hah, down to 782 bytes
02:30 rue_shop2 776
02:34 GuShH_Lap rue_shop2: premature optimization?
02:34 rue_shop2 oops I offended it
02:34 ShH_Lap can't s
02:37 wildmage GuShH_Lap, why not take this opportunity to play with OpenWorm?
02:38 wildmage http://www.openworm.org/
02:38 ShH_Lap p
02:40 Triffid_Hunter rue_shop2: yeah integrators can be tough to tame
02:40 rue_shop2 it was fine till I converted something to a char
02:40 rue_shop2 and backtrackingisn't working
02:43 rue_shop2 ah, my knocking is getting softer
11:54 rue_house http://www.ebay.ca/itm/121004906843 <-- this is a GREAT set of gears, all unique, but enough to make about anything
11:54 rue_house crown, reduction, worm, spur, great set!
11:55 rue_house and as far as gears go, pretty cheap
12:12 rue_shop2 haha I just realized that I can make the knock detector code use the pizo for pass and failure tones
12:13 MrCurious i THOUGHT i just heard a bell ring
12:32 rue_shop2 the lightbulb never got a proper acronym, so I hereby give it LEH, for Light Emitting Heater
12:34 MrCurious HELS Heat Emitting Light Source
12:42 MrCurious oh no! N. Korea has the rodman.... now they can create their freaky clone armies.....
12:43 MrCurious more troubllingly, N. Korea has now reached the "FAX" level of technicological advancement
12:49 MrCurious why does a mental image of mike myers in austin powers in a white suit holding a bald cat keep coming to mind when i hear kim jong un
13:00 jumijoze_ N. Korea is Mike Myers' performanc art
13:29 zumba_addict hey folks, where can I start about robotic fingers imitating like human finger?
13:29 Hukka Start?
13:29 Hukka I guess looking at what's been done
13:30 Hukka Most use springs and cables, with the motors operating the cables further down in the hand or arm
13:30 zumba_addict ok
13:30 Hukka googling should work, as usual
13:30 zumba_addict :) will do
13:31 zumba_addict I was just helping a friend. He wanted to use fingers to so he can automate testing of cellphones apps
13:31 Hukka Why should it then imitate a human finger
13:31 Hukka Besides, there are already robots which do exactly that
13:32 Hukka Can't remember the name though, but I remember one video where the robot goes against a human in touch screen typing contests
13:32 rue_shop2 its not like we dont have enough unemployed humans
13:32 Hukka (It was tongue in cheek, made by the team behind the testing robot)
14:11 MrCurious personally.... i think the trick isnt to make robots... that is already under way... the trick is to make robots that REPAIR robots... nobody is working on eliminating those jobs yet..
14:17 MrCurious and thus the legend of chuck norris grew.... http://newsfeed.time.com/2013/12/20/the-inevitable-chuck-norris-parody-of-jean-claude-van-dammes-volvo-ad-stunt/
14:26 GuShH_Lap MrCurious: it can't grow any more
15:28 rue_shop2 I have the code modified to detect and distinguish two knock sequences, and its still under 1k
15:56 rue_shop2 3 and its still under 1k
16:00 GargantuaSauce generalize
16:17 GuShH_Lap GargantuaSauce: we lost rue... he fell into a premature optimization blackhole.
16:17 GuShH_Lap it's time for an intervention, rue_shop2.
16:36 MrCurious step 1 of install counter in garage for drill/mill/mortisers
16:36 MrCurious clean up some spacec
16:36 GuShH_Lap MrCurious: can you clean up some space in my garage after you're done with yours?
16:37 GuShH_Lap I'll let you move the 2 meter tall safe all by yourself
16:37 MrCurious kidding me? i am feeling every year of my 47 right now
16:37 MrCurious why do i buy tools that i cant solo lift safely
16:37 GuShH_Lap you are still young
16:37 GuShH_Lap MrCurious: I ask the same question
16:37 GuShH_Lap no answer and I'm half your age.
16:38 MrCurious new rule. all tools will be titanium from now on
16:38 GuShH_Lap technically a bit more than half, sigh
16:38 GuShH_Lap I'm getting old too.
16:38 MrCurious i have a laminate counter top
16:39 MrCurious figure 2 triangles of 2xx4 should beb enough to support it
16:39 GuShH_Lap depends what will go on top
16:39 GuShH_Lap it already sounds overkill
16:40 GuShH_Lap if I could get that safe outside I'd have space for a big old milling machine..
16:40 MrCurious about 1k lbs of tool
16:40 GuShH_Lap how thick is the laminate and how big
16:40 MrCurious 4'
16:40 MrCurious 1"
16:40 GuShH_Lap do you need me to hand you clean underwear just in case?
16:40 MrCurious suppose icould plywood reinfore under it
16:41 GuShH_Lap you need a frame underneath
16:41 MrCurious 3 triangles :)
16:42 MrCurious may even morticec the sides of triangle to accept the hypotinuse
16:48 ShH_Lap eyer
16:49 GuShH_Lap doing some online tests for the new driving license... these are "simulated" tests but the only answers I got wrong were due to the poor formulation of the questions... dipshits.
16:49 MrCurious nae them
16:49 MrCurious blame
16:49 MrCurious or
16:50 GuShH_Lap they are random with multiple choices
16:50 MrCurious memorize the fucked up questions and the answers they expect
16:50 MrCurious only study wht you get wrong
16:50 GuShH_Lap true, on the other hand I know the answers but the questions are poorly formulated so I got a few wrong.
16:50 MrCurious you aready know what you get right
16:50 MrCurious you dont have a DL?
16:51 GuShH_Lap they changed the laws
16:51 GuShH_Lap and it depends on the categories
16:51 GuShH_Lap car, motorcycle, truck they're all different.
16:52 GuShH_Lap for instance "what's the maximum load a scooter can take" (I was taking a car test, why the fuck would I want to care about scooters anyway?) but the choices were 40, 80 or 100KG, I chose 100KG because that's the average standard TOTAL LOAD for a scooter (passenger), however they meant to ask load as in extra load aside from the passenger... which would've been "40" but that's also highly assumptious.
16:52 GuShH_Lap these are stupid questions.
16:52 GuShH_Lap the ones I got wrong were also highly irrelevant.
16:52 GuShH_Lap but you need 90% to pass, otherwise you have to wait a whole month to take the tests again.
16:53 MrCurious good luck
16:53 GuShH_Lap physical, mental, theoretical, practical, they charge you again and force you to run them all over again.
16:54 GuShH_Lap they even expect you to hand them a recent blood test result, you can't just say "I'm type A+" anymore, it has to be proven.
16:55 GuShH_Lap It's starting to be as annoying as the US DMV...
16:55 GuShH_Lap Now your ID also has to be updated with the latest address, it used to be you could have your address certified or verified by the police ...
16:55 ShH_Lap shakes
16:56 GuShH_Lap MrCurious: previously it was just a theoretical test and after filling up some paper work they gave you the ID, not anymore... if yours expired, good luck.
16:56 GuShH_Lap Is it any easier in the US?
16:57 MrCurious we renew by mail
16:57 MrCurious every 8 years or so, a vision test
16:57 GuShH_Lap damn you.
16:57 MrCurious after a certian ancient age, skill tests
16:58 GuShH_Lap just vision? no hearing?
16:58 GuShH_Lap no reflexes?
16:58 GuShH_Lap the hell man
16:58 MrCurious 1st....3rd....
16:58 GuShH_Lap here the age is irrelevant, everyone gets tested.
16:58 MrCurious sounds fun
16:58 MrCurious a source of national pride
16:58 GuShH_Lap in that regard I agree, but there are lots of idiots on the road and it makes you wonder how they got their license
16:58 MrCurious who says they HAVE one
16:59 GuShH_Lap they won't use the turn signals, they'll stop anywhere... they'll do U turns...
16:59 GuShH_Lap I assume so, since it's illegal to drive without one
16:59 GuShH_Lap or insurrance / registration for that matter.
16:59 GuShH_Lap which makes having a weekend bike or truck a rather expensive toy.
17:01 GuShH_Lap I just ran the high displacement motorcycle test, most of the questions are also scooter related... the hell man, how high are these guys
19:19 MrCurious that went welll so far
19:20 MrCurious decided to add front legs a kick plate, and side panels
19:21 MrCurious guess as a perk i will get a cabinet under counter
19:21 Tom_itx almost got my pendant done
19:22 MrCurious lady-pendant or cnc pendnt
19:22 Tom_itx cnc
19:22 MrCurious asking, not judging...
19:24 Tom_itx pic on the way\
19:24 MrCurious nice
19:25 MrCurious thinking i will add a shower rod/curtain type thing on side of drill press to limit alumminum fragment travel
19:30 GuShH_Lap MrCurious: wha?
19:31 GuShH_Lap toward you or everywhere?
19:31 GuShH_Lap alu always flings toward me
19:31 MrCurious it goes everywhere
19:31 GuShH_Lap one plus for ferrous metals... just add a magnet.
19:31 MrCurious cleanup is a nightmare
19:31 GuShH_Lap is it?
19:31 GuShH_Lap maybe your bits are not sharp enough
19:32 MrCurious well, if you do it
19:32 GuShH_Lap I get nice continous chips
19:32 MrCurious but if you dont, you find yourself gettting taller, and the tools getting shorter
19:32 GuShH_Lap that's why I said fling, they whip at ya.
19:32 GuShH_Lap heh
19:32 MrCurious i get corkscrews
19:32 MrCurious pain to vaccuume up withuot using the 4" vac
19:32 GuShH_Lap I put all the alu on the lathe swarf tray until there's no more space, then I move it into a bag for future smelting experiments
19:33 GuShH_Lap but with all the oil those chips have I doubt they'll be usable
19:33 MrCurious do you have access to iron filings?
19:33 GuShH_Lap not much, why
19:33 MrCurious i have heard rusting the iron
19:33 MrCurious then mixing with the alum
19:33 GuShH_Lap heh
19:33 GuShH_Lap I hardly work with iron
19:33 GuShH_Lap and I don't make aluminum powder at all
19:33 MrCurious only rust in my shop is on tools
19:34 GuShH_Lap MrCurious: leave the thermite to the kids
19:34 GuShH_Lap it's another one of Darwin's tools
19:34 MrCurious true
19:34 GuShH_Lap then again I played with lots of dangerous crap growing up, never had an incident
19:34 GuShH_Lap common sense I guess?
19:35 MrCurious i did same
19:35 MrCurious had a few incidents
19:35 GuShH_Lap any missing fingers?
19:35 MrCurious used to like to make firecrackers out of match heads
19:35 GuShH_Lap I was the family pyro / bomb maker
19:35 MrCurious never mastered the fuseing though
19:35 MrCurious set off a shotgun shell primer cap using a vise and a screwdriver/hammer
19:36 MrCurious never reapeated that one
19:36 MrCurious the 3' of flames shooting down discouraged me
19:36 GuShH_Lap I tried to set a 22 rimfire and a 32 center fire with a pellet rifle, never managed it
19:36 MrCurious and in a half houor when the bell lstopped ringing i made myself a promise
19:36 GuShH_Lap MrCurious: I thought shells needed side pressure from the barrel to properly ignite
19:36 GuShH_Lap similar issue with rounds to a certain extent
19:37 GuShH_Lap So we were both slightly stupid but yet on the safe side
19:37 GuShH_Lap The word I'm looking for is curious.
19:37 MrCurious discovered my 14" frenel lense solar furnace ignited WD40 nicely
19:37 MrCurious melted lead, and turned bricks into glass
19:38 GuShH_Lap I played with lead making my own fishing weights out of used pellets
19:38 GuShH_Lap in my mom's kitchen of course.
19:38 GuShH_Lap using soda cans as crucibles.
19:38 MrCurious learned the why behind never point a power washer at exposed skin
19:39 GuShH_Lap that I knew by example, a friend's father had tried it and blew his finger nail off.
19:39 GuShH_Lap so I never attempted such stupidity.
19:39 MrCurious also learned when racing motorcycles, avoid the seam in the center of the road. wobbles are an effect not to be sought
19:39 GuShH_Lap avoid the sides as well
19:39 MrCurious yup
19:39 GuShH_Lap lots of crap and oil in general
19:39 GuShH_Lap well not literal crap, just debris
19:39 MrCurious catching a wobble at 96MPH really shows what you are made of
19:40 GuShH_Lap specially when it's raining, damn.
19:40 MrCurious well, one way or another
19:40 MrCurious sometimes it just shows others
19:40 GuShH_Lap I started riding motorcycles at the age of 6, on a 50cc
19:40 GuShH_Lap so I've always had good control of them
19:40 MrCurious i had great control
19:41 GuShH_Lap at that time my only accidents were due to loose animals.
19:41 MrCurious 2nd worse non accident incident was on a ninja 1100? when i tried to do a 1/4 mile and dumped the clutch when it was in the red zone
19:41 GuShH_Lap I flew off the bike once, landed with my right arm against a cobbed street
19:41 MrCurious broke back tire totally free
19:41 MrCurious left 20' of s marks
19:41 MrCurious parked it, and went walkies for a few
19:42 GuShH_Lap remember going to school with my right arm full of bandages and a big grin.
19:42 MrCurious i had a pin and a screw in my ankkle from a motorcycle incident
19:42 MrCurious that pretty much ended my bike-phase
19:42 GuShH_Lap you broke the chain off?
19:42 MrCurious no
19:42 GuShH_Lap I've always been scared of that
19:43 MrCurious i hit a curb at about 45 while running s curves
19:43 GuShH_Lap chain whipping back, even though everything suggests that shouldn't happen
19:43 MrCurious crater 5' after curb, bike 10' after that, and me about 30' after that
19:43 MrCurious had an ankle the size of a mellon
19:43 GuShH_Lap this is the part where we get to compare scars?
19:43 MrCurious ambulance asked if i wanted to go to the hospitol
19:43 MrCurious i said dunno, what do you think i should do
19:44 GuShH_Lap they ask you?
19:44 MrCurious suppose that means i had a concussion too
19:44 MrCurious no helmet
19:44 GuShH_Lap I don't think you have a choice around here after that
19:44 MrCurious its been a charmed life
19:44 GuShH_Lap and you'd get your license revoked and your bike impounded.
19:45 MrCurious table saw shot a 2"x6"x3mm bar of aluminum between me and a friend last week
19:45 GuShH_Lap plus who knows what else, but if it's YOUR life at risk why do they bother YOU so much to wear safety gear? so OTHERS may be legally protected?
19:45 GuShH_Lap hey quit using wood saws for metal
19:46 MrCurious it has a aluminum blade on it
19:46 MrCurious so its an auminum saw
19:46 GuShH_Lap needs an aluminum capable operator then.
19:46 MrCurious what i really need is better hold downs than 2 sticks
19:46 GuShH_Lap U brackets of sorts and an end-stop at the back so it can't shoot off?
19:47 MrCurious i have the anti kick back hold down wheels
19:47 MrCurious but the work piece was too small to use those
19:48 GuShH_Lap it may help to drink less :p
19:48 GuShH_Lap If I had as much as a beer I won't touch the lathe for instance.
19:48 MrCurious i have a zero tolerance for intoxicaants and tools...
19:48 MrCurious they NEVER mix
19:49 GuShH_Lap The day I ignored that, I got the chuck key flying to my left.. could've hit me in the face.
19:49 MrCurious 2 shop teachers both missing thumbs from the dreaded, cursed radial arm saw
19:49 GuShH_Lap That's what you get when you forget the key on the chuck.
19:49 MrCurious my key has a spring to eject it if not held against the hole
19:49 MrCurious guess we sollved that problem here in america
19:50 MrCurious now when the rill bit binds and the work piece spins... that is a bad time
19:50 MrCurious duck, run, stratemagize
19:50 MrCurious then count fingers and compare syzes for symetry
19:51 GuShH_Lap lathe chucks? never seen that anywhere in the world...
19:51 MrCurious no long hair, no lose clothes, ,and spend more than $10 on your eye protection
19:51 GuShH_Lap and CNC chucks are almost always pneumatic or similar
19:51 GuShH_Lap ie hydraulic
19:51 MrCurious mine needs a pair of huge wrenches
19:52 GuShH_Lap wood chuck?
19:52 MrCurious nope
19:52 MrCurious need pair of 1 1/8" wrenches to tighten the collet
19:52 GuShH_Lap I only need two wrenches to install or uninstall them
19:53 GuShH_Lap MrCurious: was talking 3 and 4 jaw chucks in general
19:53 GuShH_Lap square sockets
19:53 MrCurious oh, yeah, i havent bought that expensive lathe kit yet
19:53 MrCurious not convinced lathing is for me
19:55 GuShH_Lap why not?
19:55 GuShH_Lap So antibiotics + alcohol = bad?
19:56 MrCurious yea
19:56 MrCurious alcohol is a diuretic
19:56 MrCurious effectivelly owers the dossage reieved of th antibiotic by flushing it out oof your system
19:57 GuShH_Lap hrmmm but it's half a glass of wine?
19:57 MrCurious antibiotics and birth control = parents
19:57 MrCurious so many cautions these days
19:57 GuShH_Lap how about you don't forget to pull out
19:57 MrCurious you will bring about the pague horseman on us all!
19:57 ShH_Lap bl
19:57 MrCurious what? you can pull..
19:57 GuShH_Lap pull up! pull up! says the pilot in you
19:58 MrCurious isnt that called the "rhythem method"
19:58 GuShH_Lap oh shit that sounds wrong.
19:58 MrCurious or aka, parents
19:58 GuShH_Lap I wouldn't know
19:59 MrCurious well, maybe some day you will meet a nice girl, and all that will change
20:00 GargantuaSauce hey now

20:00 Tom_itx http://tom-itx.dyndns.org:81/~webpage/cnc/pendant/pendant2.jpg
20:00 GargantuaSauce we build our companions
20:00 MrCurious good point... get to it GuShH_Lap
20:01 MrCurious function over form?
20:01 MrCurious the estop could be decidedly bigger
20:01 Tom_itx it's ok
20:02 MrCurious i am a believer in big mushrooms for the oh fuck button
20:02 GuShH_Lap MrCurious: me? a parent? HAHAHAHAHA
20:02 MrCurious welll GuShH arent you practicing those skills with kittens?
20:02 MrCurious they say you would be a purrrrrrrfect parent
20:02 GuShH_Lap just one kitten, I've taken care of kittens before...
20:03 Tom_itx http://tom-itx.dyndns.org:81/~webpage/cnc/pendant/milling2.jpg
20:03 MrCurious Tom_itx: love the big dial for pulse generation. was it spensive?
20:03 Tom_itx sixty bux
20:04 GuShH_Lap o.o
20:04 GuShH_Lap nah he probably made it himself
20:04 MrCurious maybe i can delay the project-pendant
20:04 Tom_itx http://www.pmdx.com/MPG-01
20:04 GuShH_Lap I refuse to believe he would make the rest and BUY the dial.
20:04 GuShH_Lap the hell man why is the screw visible like that
20:05 Tom_itx the engraving bits worked well but it was an experiment as to the depth
20:07 GuShH_Lap Tom_itx: do they have any use left? heh
20:07 Fiesta combining anti-biotics with alcohol is troublesome because they are both CNS depressants, taking both at once can make you REALLY sleepy.
20:07 Tom_itx of course they do
20:07 Tom_itx only used one
20:07 Tom_itx and it's still good
20:08 Fiesta oh wait i'm thinking of anti-histamines, nevermind
20:09 GuShH_Lap Fiesta: How about a glass of wine is nothing?
20:09 GuShH_Lap half a glass that is.
20:10 GuShH_Lap MrCurious: what's the maximum alcohol in blood level for riding a motorcycle where you live?
20:10 GuShH_Lap it's 0.2 here.
20:10 GuShH_Lap 0.5 for cars.. go figure.
20:10 GuShH_Lap except for first timers, 0.0 for a year.
20:25 Fiesta personally i don't worry about mixing anti-biotics and alcohol unless the label speficially tells you to
20:27 Fiesta as long as you're not approaching drunk levels of alcohol, and not goign near dangerous machinery (ie: car). oh and stay away from media awards, don't be this guy https://www.youtube.com/watch?v=PlzDHY9CRB8
20:29 Fiesta that was apparently from mixing anti-biotics and alcohol
20:29 Fiesta oh... might have been opiates
20:32 Fiesta if you are riding a motorcycle, and taking meds your not sure about, i'd have NO alcohol at all.
20:35 Fiesta personally i think it's best to aim for a zero alcohol level if you're driving. driving is super dangerous already, i'm pretty paranoid
20:36 Fiesta you know, go with industry standards.
22:39 MrCurious drill milll bench framed and topped. just need to skin the sides tomorrow
22:40 Tom_itx pics or it never happened
22:40 MrCurious will happen tomorrow when i can cover over allthe hammered over square drive screws
22:41 MrCurious due to my drill burning out
22:41 MrCurious or at least i think thts what that molten plastic smell and magic smoke was
22:42 Tom_itx gotta test the pendant now, just finished some rewiring
23:09 MrCurious even found the perfect extension cable for this power thing i got. it turns 1 3-pin ac into 3 of em, and 2 usb charging ports
23:09 MrCurious screams desktop mount
23:10 MrCurious finally a vacation day where i feel like i did something
23:11 MrCurious and i cant think of anything that says i-love-me better than microwave vindaloo
23:20 Fiesta yesssss
23:29 Triffid_Hunter MrCurious: how about saying to an actual indian person at a takeaway "please kindly make a vindaloo that's hot as if some asshole american insulted your family and culture while ordering"
23:29 Triffid_Hunter that's usually how I get what I want
23:30 MrCurious aunti-g knows what i like, i dont have to be rude
23:31 Triffid_Hunter I don't think that approach is rude at all, in fact usually I get smiles and freebies
23:33 MrCurious i usually BYO indians to the indian places
23:33 Triffid_Hunter lol
23:34 MrCurious aunti g usually chaastises them for having such blland food compared to me
23:34 Triffid_Hunter always hilarious when the staff can't pronounce papadum or similar properly
23:34 MrCurious look at him, he is a better indian than you, you should be ashamed
23:35 Fiesta Vindaloo isn't Indian btw, it's British. weird truth.
23:35 Fiesta one of those cultural appropriation things
23:36 Triffid_Hunter Fiesta: yeah I know.. indians didn't have hot chilli until the west introduced it
23:36 Fiesta no chilli rly? wow i didn't know that
23:36 Triffid_Hunter their native spices are rather more oriented towards flavour than heat
23:36 Triffid_Hunter saffron and suchforth
23:37 Triffid_Hunter so me saying "hot like <insult>" is almost a reverse-insult in and of itself
23:37 Fiesta my grandmother's family were brits living in India, and she made authentic curries hot as all hell.
23:37 MrCurious they do have lovely flavors,, but someday i just want to melt my face off
23:37 Triffid_Hunter MrCurious: frankly I don't notice unless it's hot enough for most folks' faces to melt off
23:37 MrCurious and indian has way better texxtures than thai or chinese
23:37 Triffid_Hunter which is hilarious when people feed me stuff and ask "is it hot?"
23:38 Triffid_Hunter and I'm like "oh, a mild tickle" <queue eating> <queue flapping and gasping>
23:38 Fiesta i wonder when the west introduced india to hot chilli stuff
23:39 Fiesta must have been more than 3-4 generations ago.
23:39 Triffid_Hunter Fiesta: who knows.. the western invasion of india happened long before the west had much interest in proper record keeping
23:39 MrCurious i am english... i know bland, intamitely....
23:39 MrCurious if i say food is bland....
23:39 Triffid_Hunter Fiesta: well duh, western records show occupation of india for more than 4 generations
23:40 MrCurious british and indians are careful about inviting each other over....
23:40 MrCurious apparently we have trouble leaving....
23:41 Fiesta ya
23:41 Triffid_Hunter colour me unsurprised
23:41 Fiesta my grandmother's family left during the whole pakistan split thing, fled for their lives
23:41 MrCurious o england?
23:41 Fiesta came to australia
23:41 MrCurious oh nice
23:42 MrCurious on behalf of my english roots, i would like to appologize for that whole overstaying thing. please forgive us
23:42 Fiesta it was full-on genicide happening, they were apparently stopped by some gunmen who insisted they recite the lord's praryer to prove they wern't targets. almost died.
23:43 Fiesta (ie: prove ur not hindu, or something, i'm not good with hsitory
23:43 MrCurious where was that
23:43 MrCurious africa?
23:43 MrCurious at a shopping mall a few months back???
23:44 Fiesta what is now pakistan or that disputed place (Cashmir?) or something
23:44 Fiesta ... no man thsi is my family history
23:44 MrCurious so sad
23:45 Fiesta it's mostly just stories i heard as a kid
23:47 Fiesta re: <MrCurious> on behalf of my english roots, i would like to appologize for that whole overstaying thing. please forgive us
23:47 Fiesta <Fiesta> my grandmother's family were brits living in India,
23:47 Fiesta dont' appologise to me lol
23:47 MrCurious HAH
23:47 Fiesta my roots are brit too
23:47 MrCurious fancy a spot of tea?
23:47 Fiesta yes, crumpets and what not
23:49 MrCurious fiesta so your parents/grand parents lived through the great indo-pakistan divide of hate?
23:49 Fiesta well they didn't die, so... yes?
23:49 MrCurious tense
23:50 MrCurious well, almost 10pm, must be IPA time
23:50 Fiesta i should go try to get this stuff solid in my mind, take notes, it's all a blur of stories i heard as a kid.
23:50 MrCurious IPA, why so hoppy? because i burnt al my damn taste bud off earlier at dinner
