#robotics Calendar
12:10 AM LuminaxWk: oooh Catia
12:13 AM LuminaxWk: is it as nice as what the rumour said about it? I heard it's one of the top CAD programs that most large company like Boeing uses
12:16 AM rue_house: oooh look, the lab tests show ALL the cholesterol numbers are WAY HIGH
12:28 AM youngiif: rue_house: are they going to do a stress test to check for blockage
12:30 AM rue_house: the day I'm not stressed I'll be dead
12:32 AM rue_house: I should get the levels down, or an oil company is going to take out mining rights
12:50 AM youngiif: lol yeah, so did you get some cholesterol meds or going to try adjusting diet/exercise
01:03 AM rue_house: adjust life
01:03 AM rue_house: only eat nuts, dunno
01:07 AM youngiif: you could make a robot to crack the nuts for you at least
01:59 AM z64555: uh
01:59 AM z64555: aren't nuts high in cholesteral
02:05 AM youngiif: z64555: good cholesterol maybe
02:12 AM ace4016: dietary cholesteral isn't usually detrimental to blood cholesterol. common medical myth
05:37 AM Jak_o_Shadows: Wait gives you length. Neat.
05:37 AM Jak_o_Shadows: weight
06:49 AM Tom_L: Luminax, yes it is
06:49 AM Tom_L: they teach it here at the VoTech
06:51 AM Tom_L: it's 'big brother' to Solidworks
06:52 AM Tom_L: they are quite similar but different
01:07 PM cfoch-always: 7join #Pitivi
01:07 PM cfoch-always: sorry
01:30 PM anonnumberanon: how would you compute all the subsequences of "abcd"
01:43 PM Snert_: assign an arbitrary number to each letter then do the math with the numbers then convert result back to text?
01:44 PM Snert_: not "do the math" but iterate through all the variations of the 4 numbers.
05:23 PM peepsalot: any recommended low cost, high resolution rotary encoder? quadrature would be fine. I have a feeling that DIY optointerrupter setup with laser printed encoder on transparency is the most economical for this sort of thing?
05:25 PM anniepoo_: most people seem to make a DIY one
05:26 PM peepsalot: is there a particular optointerrupter module recommended or do you DIY that part too
05:26 PM anniepoo_: any cheap optointerruptor should work
05:27 PM anniepoo_: unless you have lots of available mechnanical capabiities, your life will be better if you use a premade optointerruptor
05:27 PM peepsalot: any tutorials with BOM or something?
05:27 PM Tom_L: what sort of resolution are you looking for?
05:28 PM anniepoo_: One thing I've had trouble with with diy rotary encoders is making the disk flat and perpendicular to the shaft
05:28 PM peepsalot: 100+ steps/rev, 360 would be cool
05:28 PM Tom_L: good luck
05:29 PM anniepoo_: consider a thick disk with stripes on the edge, and the reflecting optocoupler
05:29 PM peepsalot: anniepoo_, i have a 3d printer and not afraid to do CAD, is that enough mechanical capability?
05:29 PM anniepoo_: yes
05:30 PM peepsalot: Tom_L, what resolution do you think would be reasonble
05:31 PM Tom_L: depends on the resources you have available
05:31 PM anniepoo_: I made one with 360 steps, laser engraved acrylic and then filled the engraving with black paint
05:31 PM anniepoo_: but laser print would have been fine I'm sure
05:31 PM Tom_L: if you have a laser capable of cutting SS then your apt to get alot better resolution
05:32 PM Tom_L: not all black is IR black either
05:32 PM anniepoo_: good point
05:32 PM Tom_L: inkjet black fail, laser toner black pass
05:33 PM anniepoo_: yes, in fact I once made a bar code system that used toner printed on black construction paper
05:33 PM anniepoo_: 8cD
05:33 PM peepsalot: are there visible light interrupters?
05:34 PM anniepoo_: generally you want ir because the visible light environment is more dynamic
05:38 PM peepsalot: hmm, i guess this one isn't reliable for positioning because it looks like its only one interrupter,and two are needed for direction and "debouncing" if the sensor is teetering on an edge http://www.ebay.com/itm/Photoelectric-Speed-Sensor-Encoder-Coded-Disc-wheel-for-Freescale-Smart-car-D-/112030673020
05:40 PM peepsalot: anniepoo_, what diameter was your 360 step encoder?
05:40 PM peepsalot: and hell no i don't have a laser that can cut SS, lol
05:45 PM anniepoo_: about 6"
06:13 PM synja: i need a plasma cutter, speaking of
07:25 PM zhanx: peepsalot: I know someone that has a laser cutter that can
07:36 PM anniepoo_: synja, I know of a guy who does plasma cutting, cheap
07:36 PM anniepoo_: he's done stuff for me
07:38 PM synja: even a basic unit can do quite a lot and they aren't _that_ expensive
07:38 PM anniepoo_: peepsalot, that looks ok. buy two of them, mount them on a shaft with some way to slightly adjust
07:38 PM synja: i just haven't gotten around to buying one
07:39 PM anniepoo_: rotate the shaft and watch the output on a scope, adjust, watch.
07:39 PM anniepoo_: you can get 90% of it by sighting down the shaft axis and turning one until its vanes obscure the holes in the other
10:02 PM zumba_addict: good evening folks. What type of motor do I need if I want it to lift like a bike around 40-50 lbs?
10:03 PM anniepoo_: how fast?
10:03 PM anniepoo_: the motor's usually connected to a 'power train'
10:03 PM anniepoo_: if you have a tiny motor you can lift a locomotive if you do it slowly enough
10:04 PM anniepoo_: (exaggerating, friction losses in the train will stall a tiny 'toy' motor in that case, but in general, it's true)
10:06 PM anniepoo_: zumba, how far are you lifting the bike?
10:13 PM anniepoo_: strange - asked question, still in channel, has disappeared
10:13 PM anniepoo_: @zumba_addict
10:17 PM rue_house: cooool, so far the numebers comming out of my trapazoidal calc are working...
10:21 PM rue_house: Virtual peak velocity at X = 2.000
10:21 PM rue_house: Start position: 0.000
10:21 PM rue_house: End position: 3.000
10:21 PM rue_house: Peak Velocity: 1.000
10:21 PM rue_house: Time accelerating: 1.000
10:21 PM rue_house: Time jogging : 2.250
10:21 PM rue_house: Time decelerating: 0.500
10:21 PM rue_house: Accel travel distance 0.500
10:21 PM rue_house: Jog travel distance 2.750
10:21 PM rue_house: trapazoid: 0,0 1.000,1.000 3.250,1.000 3.750,0
10:23 PM Tom_L: yay
10:24 PM rue_house: have to run more numbers thru it, but looking good so far
10:25 PM rue_house: almost NOBODY does different accel and decel rates
10:25 PM rue_house: I did :)
10:25 PM Tom_L: how so?
10:25 PM Tom_L: on demand or as a setting?
10:26 PM rue_house: you pre-setup the motion
10:26 PM rue_house: it builds the profile data
10:26 PM Tom_L: oh, you mean separate accel rate and decel instead of using the same rate for both
10:26 PM rue_house: from there, the interpolator uses it to know the delay between the positions it works out
10:26 PM rue_house: yea
10:26 PM Tom_L: if it's the same mass why would it matter?
10:27 PM rue_house: the stuff I saw on the internet, EVERYONE, even the people who can use different accel and decel rates, set it the same
10:27 PM rue_house: cause I'm pretty sure a stepper can decel faster than it can accel
10:27 PM synja: lol
10:27 PM Tom_L: even under load?
10:27 PM rue_house: but the completeness makes me feel good
10:27 PM synja: especially under load
10:29 PM zumba_addict: sorry, I had to help my wife anniepoo_
10:30 PM rue_house: aha
10:30 PM rue_house: negitive jog time, caught it
10:30 PM rue_house: k
10:33 PM zumba_addict: i'd like to build similar to this anniepoo_ - https://www.facebook.com/goodgoodgadgets/videos/323020981459701/?hc_ref=ARRabFtSLv9rNwCkA_KuGrl_oJXi12Dzmml9y599hAHSSc0fTc03_EwSIe2F-enIy08
10:33 PM zumba_addict: i just a motor and this guy is using a big motor - https://www.youtube.com/watch?v=kjlZHgo2w-Q
10:34 PM zumba_addict: that's a huge motor!
10:34 PM synja: lmao
10:34 PM synja: knowing me, i'd buy the cheapest, highest gauge possible and it would crush me one day
10:36 PM anniepoo_: ok
10:38 PM anniepoo_: ok, well, that platform weighs substantially more than 50 lbs
10:39 PM anniepoo_: and yes, if you're lifting something, you're responsible for it not killing someone underneath
10:39 PM anniepoo_: the garage-attic lift construction video uses a cheap off-roading winch
10:39 PM zumba_addict: ok :D
10:40 PM anniepoo_: so, you're really making a platform?
10:40 PM zumba_addict: When I saw the video, I feel like not doing it anymore :D
10:40 PM anniepoo_: what does it weight, what does the bike weigh, is it possible for someone to climb on it without thinking?
10:40 PM zumba_addict: looks like a lot of work. I can do it
10:40 PM zumba_addict: bike is around 35-40 lbs
10:41 PM anniepoo_: if I were just going to raise a bike, I'd use an old fashioned block and tackle
10:41 PM anniepoo_: how far are you lifting the bike?
10:41 PM synja: not sure if it's worth it
10:41 PM anniepoo_: and a strap that goes around the bike
10:41 PM synja: lol
10:41 PM zumba_addict: I was just thinking because I like automating stuff. I just finished controlling my garage door with NodeJS on pi
10:41 PM synja: node? really?
10:41 PM zumba_addict: yup
10:41 PM synja: not bluetooth?
10:42 PM synja: it has to go on the internet?
10:42 PM zumba_addict: ip address
10:42 PM zumba_addict: but i can control it from the internet too
10:42 PM synja: ik, but there seems to be simpler ways of doing it
10:42 PM zumba_addict: i have my web server exposed
10:42 PM zumba_addict: to me it's simple
10:42 PM synja: filters my man, FILTERS!
10:42 PM anniepoo_: bluetooth is a low level transport protocol, synja, nodejs is a web application framework
10:42 PM synja: even if they're metaphorical
10:42 PM zumba_addict: i just used relay module connected to the liftmaster
10:42 PM synja: anniepoo_, i'm well aware
10:42 PM synja: ;)
10:42 PM anniepoo_: anyway, I
10:44 PM anniepoo_: I'd suggest a simpler, lighter system, simply because if you're making something as heavy as that platform, you should have a real engineer involved
10:45 PM synja: nah it wouldn't really be that bad
10:45 PM synja: just know the max strength of each material
10:45 PM synja: plan accordingly
10:45 PM synja: it just seems unnecessary
10:46 PM zumba_addict: i mean, it's cool implementing for fun and learning
10:46 PM synja: although it would be a little nerve wrecking for the first few weeks standing underneath them
10:46 PM synja: lel
10:46 PM zumba_addict: scary :)
10:47 PM zumba_addict: btw, this is what I use to turn on/off a gpio pin on pi - https://www.npmjs.com/package/onoff
10:47 PM anniepoo_: so, I'd do something a lot more conservative
10:47 PM anniepoo_: and maybe fun
10:47 PM zumba_addict: yup, true
10:47 PM synja: personally i'd just stack everything in a corner until it reaches the ceiling
10:47 PM zumba_addict: btw, does robotics subject in college has programming? it's because my son is going to college next year
10:48 PM anniepoo_: figure out a 'crane' system where you can park your bike more or less in a spot, and push a button, and a hook comes down and picks up your bike
10:48 PM zumba_addict: will do
10:48 PM anniepoo_: yes, lots of progrramming in robotics
10:48 PM anniepoo_: esp. in academia
10:48 PM synja: i would hope so
10:48 PM zumba_addict: we went to University of Illinois
10:48 PM synja: if not, i'd wonder what they're really teaching them
10:48 PM anniepoo_: is this a 4 year college or a mechatronics program at a trade school?
10:49 PM synja: either way should be programming
10:49 PM synja: zumba_addict, i take it he doesn't have much exp. with it?
10:49 PM zumba_addict: yes, it's 4 yrs
10:50 PM zumba_addict: he did some robotics in highschool
10:50 PM synja: i meant programming
10:50 PM synja: sorry
10:50 PM anniepoo_: then it's lots of math and programming
10:50 PM zumba_addict: oh cool
10:50 PM zumba_addict: he is good in math
10:50 PM zumba_addict: i taught him python
10:50 PM synja: good to start with a debugging lang.
10:50 PM zumba_addict: he got it quickly but he forgot it now because of no practice
10:50 PM anniepoo_: a good robotics curriculum would include a crap ton of dynamics of nonrigid systems and other scary stuff
10:50 PM synja: little less frustrating
10:51 PM zumba_addict: then he tweak minecraft plugins
10:51 PM synja: that's good
10:51 PM synja: if you can tweak, you understand at least a part of it
10:51 PM zumba_addict: i really hope he gets accepted in UIUC
10:51 PM synja: as long as it wasn't brute forced ;)
10:51 PM zumba_addict: yup, that's good
10:51 PM zumba_addict: :D hehehe
10:51 PM zumba_addict: i do brute forcing to see how everything works
10:51 PM zumba_addict: and reverse engineering
10:51 PM synja: for RE it's a decent tactic
10:52 PM synja: but you should know what everything does
10:52 PM zumba_addict: yup
10:52 PM synja: brute force is a beginner programmer's technique, but still valuable in learning causation between things
10:52 PM zumba_addict: i'm studying assembly language now. Our prof in 1993 was really bad
10:52 PM synja: :(
10:52 PM synja: that's a shame
10:52 PM zumba_addict: for one semester, she only taught us how to display alphabet
10:53 PM synja: sounds like she didn't know much about it
10:53 PM zumba_addict: looks like she didn't know. And she gave us a very high grade because she doesn't want us to report
10:53 PM zumba_addict: we were shocked with our grades
10:53 PM synja: lmao
10:53 PM zumba_addict: i know
10:53 PM synja: yeah clear sign
10:54 PM zumba_addict: i'm really weak in electronics :(
10:54 PM zumba_addict: but i did learn few stuff
10:54 PM z64555: in which aspect
10:54 PM synja: prob. a lot if he included the entire field
10:55 PM zumba_addict: like how would i know which part to use to do that. I had to ask in #electronics what I want and they told me what I need and how to connect. I was able to follow it :)
10:55 PM zumba_addict: i built a motorized camera slider from scratch using arduino
10:55 PM synja: you know how to solder?
10:55 PM zumba_addict: yes
10:55 PM synja: good
10:55 PM zumba_addict: let me see if I have a youtube of my project
10:55 PM z64555: know how to breadboard? :P
10:55 PM anniepoo_: it's how everybody starts
10:55 PM synja: what kind of question is that z64555 lol
10:56 PM z64555: a joke of a question :P
10:56 PM synja: :P
10:56 PM zumba_addict: ah, this is the old version - https://www.youtube.com/watch?v=IhHrrqmwf-E
10:56 PM zumba_addict: it looks so very cool now
10:56 PM zumba_addict: let me upload a pic
10:57 PM synja: holy crepe
10:57 PM synja: looks like my client's server room
10:57 PM * anniepoo_ is installing arduino ide on linux because windows machine doesn't like this board for some reason
10:57 PM zumba_addict: here is my latest - http://imgur.com/a/5kGFy
10:58 PM zumba_addict: so that device on plexi glass is the same as on my video but i redesigned it
10:58 PM zumba_addict: i'm using 2 arduino nano
10:58 PM synja: nice
10:58 PM zumba_addict: it controls the stepper motor on dolly and another motor to swivel the camera
10:59 PM zumba_addict: then it also controls the shutter of my camera
10:59 PM synja: one can never have too many relays
10:59 PM synja: unless you're rue
11:00 PM rue_house: ok, now isolate that for A
11:00 PM rue_house: AWE !@#$%@#$^!#@#$
11:01 PM rue_house: d = ((A*a)(A+((A*(1-r))/r))/2
11:01 PM rue_house: anyone?
11:01 PM synja: that looks too familiar
11:01 PM Tom_L: now you're just grasping at straws
11:02 PM rue_house: I'm redoing my approach
11:02 PM zumba_addict: and here is the first version of my motorized camera dolly - https://www.youtube.com/watch?v=A95uCHp5Q7Q
11:02 PM anniepoo_: hang on rue
11:03 PM rue_house: wolfram says its the same as a*A^2/2*r
11:03 PM anniepoo_: 8cD
11:04 PM rue_house: if so, A = sqrt((2*r*d)/a)
11:04 PM anniepoo_: yup
11:08 PM synja: zumba_addict, maybe your son shouldn't know too much about programming before he starts college
11:08 PM synja: i was programming since 9 and when i started at 16 for a SE degree it bored me to quitting
11:08 PM zumba_addict: i start 9 too
11:08 PM synja: code brothers!
11:09 PM zumba_addict: i'm still loving it :D
11:09 PM rue_house: :( I was older before they let me at a computer
11:09 PM synja: really? i hate it
11:09 PM zumba_addict: i love it
11:09 PM synja: ughhh
11:09 PM rue_house: I'm a recreational coder
11:09 PM synja: i used to love it but now it's just means to an end
11:09 PM Tom_L: at 9 they didn't have computers yet...
11:09 PM z64555: I messed around with a C64 around 9, 12
11:09 PM zumba_addict: i code in c/c++, javascript, python, perl, php, unix shell
11:09 PM z64555: still have it, too
11:09 PM zumba_addict: nice
11:09 PM z64555: dad picked them up in a garage sell somewhere
11:09 PM synja: i don't count webdev as real programming :P
11:09 PM zumba_addict: i have trs-80 back then
11:10 PM zumba_addict: really, why not?
11:10 PM z64555: not a whole lot of logic operations taht you can do with it
11:10 PM z64555: I think, I dunno
11:11 PM zumba_addict: it's more of sockets programming
11:11 PM zumba_addict: network calls
11:11 PM * anniepoo_ is currently doing web development in a logic language
11:11 PM anniepoo_: 8cD
11:11 PM zumba_addict: :)
11:11 PM * anniepoo_ is doing LOTS of logic operations
11:11 PM synja: it's mostly aesthetics and making things practical for idiot users
11:11 PM zumba_addict: web dev is for aesthetics?
11:11 PM synja: ik ik much of the same shit goes into it
11:11 PM synja: well the higher up langs
11:12 PM synja: moreso
11:12 PM zumba_addict: for me, it's still a nice programming language
11:12 PM synja: it's about delivering content, not really anything physically practical
11:13 PM zumba_addict: not just for aesthetics. The reason why i enjoy it is because I build api then call the api from a web application. But in between, I also build servers like nginx and get firewall to allow network traffic from one tcp port to another
11:13 PM anniepoo_: nrrrgh
11:13 PM synja: if you're dealing with backend it becomes less boring
11:14 PM synja: i suppose that's my real issue with it
11:14 PM zumba_addict: yup, i love sniffing network traffic as part of troubleshooting issues :D
11:15 PM zumba_addict: i get bored on web application development if it goes beyond 3 months
11:15 PM zumba_addict: very bored :D
11:15 PM anniepoo_: fudge
11:15 PM synja: i think i've only coded 1 thing that has taken more than 3 months to finish
11:15 PM zumba_addict: i enjoy my own home automation projects. I recently created a reactjs app that controls my lawn sprinkler system :D
11:15 PM synja: and i'm still working on it
11:15 PM anniepoo_: gonna have to log out and back in
11:16 PM zumba_addict: thanks anniepoo_
11:16 PM synja: what about a moisture sensor in the ground? that way it doesn't need to be networked at all
11:16 PM anniepoo_: yah, I may be unavail for 10 mins or so
11:16 PM anniepoo_: lots of stuff running!
11:16 PM zumba_addict: previously, I used AngularJS for the web application
11:16 PM zumba_addict: cool
11:16 PM synja: bah! angular
11:17 PM zumba_addict: angular is crap
11:17 PM synja: meh it's ok i just don't like it
11:17 PM zumba_addict: but that's what I used 3-4 years ago
11:17 PM zumba_addict: now I don't like it. I love ReactJS
11:17 PM zumba_addict: it worked great at that time :D
11:18 PM synja: or you could make a nodejs script to check your local weather station each day to find out if it's going to rain
11:18 PM synja: if you don't have the sensors
11:18 PM synja: home automation is fun though
11:18 PM synja: i'll give you that
11:19 PM rue_house: till your radiator springs a leak
11:19 PM rue_house: and the boiler goes off
11:19 PM zumba_addict: yeah, here is my lawn sprinkler project but this is old. The new one is written in ReactJS and the UI is great :D https://www.youtube.com/watch?v=Pf2xG8N6iuA
11:19 PM rue_house: from lack of a flow sensor
11:19 PM synja: if i had a garage, i'd prob. hook it up to image rec for the license plate and ocr to read it
11:19 PM rue_house: :)))) code is now passing my tests
11:19 PM zumba_addict: that's cool idea synja
11:19 PM synja: prob. be a neat project to do with your son
11:20 PM zumba_addict: yup
11:21 PM zumba_addict: i really like that idea! :D
11:21 PM synja: just don't make it on a timeout lol
11:21 PM zumba_addict: i'm not sure how that camera will last in our weather here in chicago
11:21 PM synja: lest the door closes on your car half way through
11:21 PM synja: yeah maybe plexiglass or something
11:21 PM zumba_addict: ah, cool
11:22 PM zumba_addict: might need some cleaning once a month which is not bad
11:22 PM synja: yeah little room for errors there
11:22 PM zumba_addict: i can just call my existing api :D
11:22 PM zumba_addict: now i need to find a camear
11:22 PM synja: keep it offline! lol
11:23 PM zumba_addict: :D
11:23 PM synja: tesseract for ocr
11:23 PM zumba_addict: nice!
11:23 PM synja: make things as simple as they need to be, but no simpler
11:23 PM zumba_addict: i'm stoked right now!
11:23 PM synja: kudos
11:23 PM zumba_addict: i'm very sure i can do it :D
11:23 PM zumba_addict: i'll ask my son to write the code
11:23 PM synja: oh yeah it would be an easy project
11:23 PM zumba_addict: i'll guide him
11:24 PM synja: wouldn't take more than 3 hrs from design to implementation
11:24 PM synja: but to teach him, maybe 3 days
11:24 PM zumba_addict: yup
11:24 PM synja: i mean, to go through everything with him
11:24 PM zumba_addict: will do
11:24 PM synja: i'd like to see a video of that!
11:25 PM rue_house: zumba_addict, virtual motorized slider, starts at zero, how far is it to travel (give me a number, unitsless)
11:25 PM zumba_addict: virtual?
11:25 PM zumba_addict: i've calculated my rail, it's about 3200 steps to reach end to end
11:25 PM rue_house: 3200 ok
11:25 PM zumba_addict: it's a stepper motor
11:26 PM rue_house: specify an acceleration
11:26 PM rue_house: rate, unitsless
11:26 PM zumba_addict: but I have a switch at the end that when pressed by the dolly, it turns off
11:26 PM rue_house: give me a number or I'll kill the bunny!
11:26 PM zumba_addict: i only need an acceleration when I do manual recording
11:27 PM zumba_addict: but for regular timelapse, the movement is always 4 steps, then it takes a picture
11:27 PM rue_house: }:| giiiive me a numberrrrr...
11:27 PM zumba_addict: number?
11:27 PM rue_house: yes, an acceleration
11:27 PM rue_house: uniteless give me a number
11:27 PM zumba_addict: 100
11:27 PM rue_house: ok
11:27 PM rue_house: now deceleration rate
11:27 PM zumba_addict: upto 250. 500 is so quick that stepper motors starts to miss
11:27 PM rue_house: 250 ok
11:28 PM rue_house: now a maximum velocity
11:28 PM zumba_addict: i didn't work on that part
11:28 PM rue_house: 500 ok
11:28 PM zumba_addict: ok
11:28 PM rue_house: Virtual peak velocity at 71.429 % travel
11:28 PM rue_house: Virtual peak accel time at 6.761
11:28 PM rue_house: Start position: 0.000
11:28 PM rue_house: End position: 3200.000
11:28 PM rue_house: Peak Velocity: 500.000
11:28 PM rue_house: Time accelerating: 5.000
11:28 PM rue_house: Time jogging : 2.900
11:28 PM rue_house: Time decelerating: 2.000
11:28 PM rue_house: Accel travel distance 1250.000
11:28 PM rue_house: Jog travel distance 1450.000
11:28 PM rue_house: Decel travel distance 500.000
11:28 PM rue_house: trapazoid: 0,0 5.000,500.000 7.900,500.000 9.900,0
11:29 PM zumba_addict: damn math! :D
11:29 PM zumba_addict: i couldn't even decipher it :D
11:29 PM rue_house: Area: 3200
11:29 PM rue_house: YEAAAAAAAAAAAA
11:30 PM zumba_addict: :D
11:31 PM zumba_addict: i'd like to share this, here is one of the results created by the motorized camera slider I built - https://www.youtube.com/watch?v=-0b3CuZpHP4
11:32 PM rue_house: nice
11:32 PM rue_house: whats the frame interval?
11:32 PM rue_house: OR THE BUNNY GETS IT!!!
11:33 PM synja: rue_house, are you on drugs?
11:33 PM zumba_addict: 24fps
11:33 PM zumba_addict: lol
11:33 PM rue_house: I HAVE A CONDITION, I DONT NEED DRUGS!
11:33 PM rue_house: duh, no
11:33 PM rue_house: the time/frame
11:33 PM synja: maybe you should be
11:33 PM synja: :}
11:33 PM zumba_addict: each pic could be 3 seconds and interval is like 1 second
11:33 PM rue_house: I just wrote code that nobody could figure out
11:33 PM rue_house: ah
11:34 PM zumba_addict: that's why it's smooth
11:34 PM rue_house: I dont need drugs
11:34 PM synja: no incentive no context
11:34 PM synja: aww drugs are fun!
11:35 PM zumba_addict: my officemate takes cannabis
11:35 PM zumba_addict: he has a card
11:35 PM rue_house: now I'll have a trapazoidal velocity profiler for my linear interpolator
11:35 PM synja: by what you called it, i take it you've never tried pot
11:35 PM zumba_addict: he is allowed to take it
11:35 PM zumba_addict: i did tried when i was 15
11:35 PM rue_house: I might break 100 characters for a function name!
11:35 PM zumba_addict: i'm very old now
11:35 PM zumba_addict: i mean, not really old
11:36 PM synja: lol
11:36 PM zumba_addict: 45
11:36 PM synja: that's not bad
11:36 PM zumba_addict: i'm still very fit since I work out like 4-5 times a week
11:36 PM synja: i guess that's your drug then
11:36 PM zumba_addict: yup
11:36 PM zumba_addict: i'm addicted to it
11:36 PM z64555: healthier, too
11:37 PM zumba_addict: but I need to correct my sleeping habits. i stay late so bad, like 3-4am, just coding
11:37 PM synja: yeaaaaah
11:37 PM zumba_addict: i've tried so many times and it doesn't work
11:37 PM synja: i can't give advice against that
11:37 PM zumba_addict: i started using irc 1995
11:37 PM z64555: just ride it out
11:37 PM zumba_addict: i got addicted to irc
11:37 PM zumba_addict: i started on efnet
11:37 PM z64555: otherwise you'll just stay awake thinking of things to do in code
11:38 PM zumba_addict: i learn a lot from irc rather than forums
11:38 PM zumba_addict: exacty, that's true
11:38 PM synja: mhm
11:38 PM rue_house: zumba_addict, so, your a recrational coder?
11:38 PM zumba_addict: i think, i'm thinking that if I stop using computer, i'll miss a lot
11:38 PM synja: then when you're almost asleep you'll jump out of bed half naked and sit at the computer for another hour
11:38 PM zumba_addict: what does that mean rue_house?
11:38 PM rue_house: it means you code for fun
11:38 PM synja: damn ideas
11:38 PM zumba_addict: oh yes, that happens synja
11:39 PM synja: lol
11:39 PM zumba_addict: i'm worried that it's going to affect me when i'm in 60
11:39 PM z64555: nah
11:39 PM synja: at least you won't have to sleep as much!
11:39 PM synja: lmao
11:39 PM zumba_addict: i keep reading that sleeping 2-3 hours affect people
11:39 PM z64555: learn to powernap
11:39 PM zumba_addict: and people have been telling me too
11:39 PM zumba_addict: i do powernaps on train
11:40 PM z64555: ok, that might also be affecting your sleep schedule. BUt if you're able to make it so that it's fairly regular like bi-phasic, then you should be good
11:40 PM synja: but then the weekend comes along
11:40 PM zumba_addict: :D
11:41 PM zumba_addict: do you folks suffer from it?
11:41 PM zumba_addict: i've been doing this since 1991
11:41 PM synja: totally irregular sleep schedule, but i work for myself
11:41 PM synja: so i can get away with it
11:41 PM synja: with no family
11:41 PM zumba_addict: cool
11:41 PM z64555: I drank a few too many energy drinks in my teens, I don't have a regular sleep schedule anymore
11:41 PM anniepoo_: night
11:42 PM z64555: g'night annie
11:42 PM synja: toodles anniepoo_
11:42 PM zumba_addict: ah, that's a lot of caffeine z64555
11:42 PM synja: z64555, when i was a teenager i drank a 2 liter of mtn. dew each day
11:42 PM z64555: Eh, caffeine alone isn't the culprit
11:42 PM z64555: its the sugar, taurine, and other junk
11:42 PM synja: the benzoates will dull you down too
11:43 PM synja: preserve your drink, but not you
11:43 PM z64555: of course
11:43 PM zumba_addict: oh, i tried bronkaid around 6pm. Damn I was awake so much!
11:43 PM synja: never heard of the stuff
11:43 PM synja: energy drink i take it
11:43 PM zumba_addict: i read it on bodybuilding.com so I tried
11:43 PM z64555: speaking of which, I'm due for another green tea detox
11:43 PM zumba_addict: it really boosted my energy but the side effect like urinating is hard, lol
11:44 PM z64555: where I basically binge-drink the stuff for about a week
11:44 PM synja: yuck
11:44 PM z64555: well not binge-drink, but yeah
11:44 PM synja: zumba_addict, sounds like you could benefit from a stadium pal!
11:44 PM synja: ...or a large bucket
11:44 PM synja: jk
11:44 PM zumba_addict: lol
11:45 PM z64555: stadium pal? oh no
11:45 PM anniepoo: 8cD ok, I'm back for a bit - was rebooting because I needed to change some serial port settings
11:45 PM anniepoo: the robot's ready for first power up, I couldn't leave it at that
11:46 PM z64555: :P
11:48 PM anniepoo: ok, I have blinky
11:48 PM z64555: I need to do a regular cardio routine, but I live in a wooded area that requires a bath in deet before stepping outside
11:48 PM zumba_addict: alright folks, thanks for the chat! I'll try to sleep early tonight
11:49 PM zumba_addict: wife is calling :D
11:49 PM z64555: g'night
11:50 PM zumba_addict: you too z64555
11:52 PM synja: anniepoo, the snail?
11:52 PM anniepoo: dancing robot
11:52 PM synja: oh
11:52 PM anniepoo: and the servos are drawing too much juice
11:52 PM synja: :/
11:53 PM synja: i really need to teach my robot to plug itself in
11:58 PM anniepoo: think I just toasted my arduino
11:59 PM synja: at least they're cheap
11:59 PM synja: well i'm off for the night
11:59 PM synja: toodles all
11:59 PM anniepoo: yep
