04:28 Veverak rue_shop4: well
04:28 Veverak let's say I won't if I found there is better way
04:28 Veverak like for gearbox... which geras I will buy somewhere...
04:28 Veverak :)
04:28 Veverak *gears
04:28 Veverak Hyratel: didn't found one
04:29 deshipu Veverak: this may be interesting to you: http://lcamtuf.coredump.cx/gcnc/
04:30 deshipu Veverak: that guy started it to make gearboxes
04:34 Veverak aaah! tahnks a lot :)
04:35 Veverak one thing is that I don't really feel like printing gears
04:41 Veverak nah, working with that python code starts to be pain in the ass, have to finally implement caching for calculations
06:45 deshipu https://www.youtube.com/watch?v=7r9Gmi-WK7I
06:45 deshipu some cool stuff with modular designs
07:19 Veverak deshipu: wow
08:11 Mister whorunbartertown
08:12 Mister lol missclicked a macro..
08:12 orlock masterblaster
08:12 orlock masterblaster runs bartertown!
08:13 Mister Does anyone know of an electrical engine that can is good for moving a pole up and down? and that can stop and hold weight
08:13 orlock either a linear actuator for short distances
08:14 orlock or well, a wheel on a pole (with a few more) for long distances
08:14 Mister hmm i tihnk i need more then 1 rotation
08:14 orlock how longs the pole?
08:14 Tom_itx worm gear
08:14 Mister 1.5meters
08:14 Mister -20cm to hold it steady
08:15 Mister orlock aha Thanx! just what i need i think
08:15 deshipu maybe make a step backwards and tell us what you are trying to do with the pole
08:16 deshipu I would just hand it on a piece of string and have the string spooled...
08:16 deshipu s/hand/hang
08:17 Mister was thinking of that too, using a chain
08:18 Mister it has to hold around 60kg
08:18 Mister when it stops
08:18 deshipu how fast does it have to move?
08:18 Mister as quickly as possible
08:19 deshipu well, any speed is possible, as long as you have the money ;)
08:19 Mister hopefully, in the future it'll be so fast that the botton can fall while the op will stand still (x,y,z coordinates)
08:20 deshipu I don't understand what you just said
08:20 deshipu especially the 'x, y, z coordinates' seems to be a non-sequitur
08:20 Mister i can't explain by words :-S here's a flash movie of it Tundra-telebotics.com
08:20 Veverak nah
08:21 Veverak anybody exp. with gearboxes?
08:21 Mister english is like my 3rd or 4th language
08:21 verak wonders how much space he practically needs between gears and gearbox
08:21 orlock hydraulics maybe
08:21 Veverak https://cloud.veverak.org/public.php?service=files&t=d6b5d3ae2acbbed45e09c5aca946821f
08:21 deshipu Veverak: that link I gave you has some practical tips about gear geometry and usch
08:21 deshipu such
08:22 Veverak deshipu: yeah, but I didn't noteci nfo about the box itself... especially the question I asked :D
08:22 Veverak deshipu: btw: using script I found once for gears just for ilustration
08:22 Mister that link is an old design btw, it'll be easier to make the one i'm working on now
08:22 Veverak going to buy one anyway :)
08:22 deshipu Mister: and the camera is 60kg there?
08:23 Veverak and yeah, distance between gears is the ... ideal?
08:23 Mister deshipu, it's made for news channels and their camera crew
08:23 Mister and including the pole that moves up and down
08:24 deshipu there are some ready camera gimbals out there that already do it
08:24 Mister since they have very high resolution, thery can make digital picture stabilazation in addition to mechanical
08:24 deshipu they are expensive for a reason
08:25 deshipu with 60kg you are going to have huge inertia
08:26 deshipu so the actuator has to handle much more than that
08:26 Mister deshipu: i'm kinda in the starting phase however, i don't really want to make too many drawings before they are needed, so all the detals of "Cammie" are variables at the moment
08:26 Mister and that had me thinking lol
08:26 deshipu it's a hard problem
08:27 Mister i tihnk it's possible to make a program that can decide how a tool should be constructed
08:27 Mister and what it'll look like
08:27 Mister but nvm lol.. i usuawly drive away from the subject when speaking of these things x-D
08:27 Mister usually*
08:29 Mister Deshipu: hmm, i tihnk a custom actuator will work, i was also thinking of using that but i didn't know what it was called in engliush
08:30 deshipu Mister: the problem is that you need a lot of force
08:31 Mister deshipu: indeed, i'm guessing around 4.5KW at maximum
08:32 Mister oh btw
08:32 Mister the prototype doesn't need to carry 60kg
08:32 Veverak let's maker obots doesn't work? :/
08:32 Mister and you will have a much cheaper one that can go to the stores and shop for you =)
08:32 deshipu Veverak: yeah, they have some server problems recently
08:32 Mister with arms
08:33 deshipu https://en.wikipedia.org/wiki/Steadicam
08:34 Mister hmm
08:35 Mister anyone have an advice? should i try to sell the design to someone?
08:35 Mister like steadycam
08:36 Mister i can't stop imagening what will happen if they are weaponized
08:36 Mister and armored
08:39 deshipu I'm afraid they are already there, and possibly also patented
08:40 Mister steadycam? or humans weaponizing this tool?
08:42 deshipu Mister: have you seen Aliens 2? :)
08:42 Mister deshipu: tihnki'v only seen the last alien and predator stuff :-P
08:43 deshipu Mister: http://1.bp.blogspot.com/_1luLRXKoJM8/Rz6Elf0z7yI/AAAAAAAABF8/K0nrIC4b1u4/s400/vas3.jpg
08:43 Mister lol.. very interesting >.<
08:44 Mister i thought of something similar but it would replace the waepon straps around your shoulder
08:45 deshipu yeah, there are various models, this one is a fiction, from a movie
08:45 deshipu it's called 'smartgun'
08:45 deshipu if you look for 'smartgun harness' you can see a lot of people re-creating it for their paintball guns
08:45 Mister hehe cool x-D
08:46 Mister must have one of these autoaim systems: http://www.youtube.com/watch?v=6QcfZGDvHU8
08:47 Mister can have one gun on each shoulder lol
08:47 Mister and still use arms
08:49 Mister deshipu: you arn't supposed to carry cammie like those steadycams btw
08:49 Mister dunno if you saw the drawing or not
08:50 deshipu Mister: seriously, watch Aliens 2, you will love it :)
08:50 Mister i will =)
08:52 Mister deshipu: i was wondering.. do you know anything about patents and register of design?
08:53 deshipu no, and it differs between countries a lot
08:56 Mister k hmm.. i must find out what kind of drawings that is needed
08:56 Mister in order to register a design
10:16 choonway http://www.wipo.int/portal/en/index.html
13:39 armyofevilrobots rue_shop4: rue_house Feeling better?
13:57 deshipu since you are so much into mills and latches, this may interest you: http://credentiality2.blogspot.ca/2015/01/radial-mill.html
14:01 Veverak well
14:01 Veverak finally finished the gearbox
14:01 Veverak but that definition of that...
14:02 verak got blood t
14:03 deshipu Veverak: wait for when you try to print it...
14:04 Veverak http://pastebin.com/583f77eb
14:04 Veverak beat this
14:05 Veverak https://cloud.veverak.org/public.php?service=files&t=29ccb25f993daea04d3bc3b1fbbe53a4
14:06 Veverak but yeah well, it's not like I am not happy with the output of that code :)
14:07 Veverak https://cloud.veverak.org/public.php?service=files&t=efc03da17e4d414433c1b9a82f7301e2 another view
15:59 Mister does actuators usualy have a way to register how far out it is? like in a servo
16:03 devshark do they have the odometric circle around their moving part?
16:04 devshark if not then no.
16:04 devshark if yes, then yea but you need to "recalibrate" (clamp it back to 0 when you know it's at 0) from time to time.
16:12 Mister devshark: aha cool ty=)
16:13 Mister do you konw if there are any names that refer to those with a sensor?
16:13 Mister know*
16:14 deshipu Mister: you can connect an extra wire to a servo's pot
16:14 deshipu Mister: to get a cheap position-reading actuator
16:15 Mister deshipu: hmm is that 1024 different positions?
16:17 Mister that was very interesting btw x-D
16:17 deshipu Mister: no, it's analog
16:18 deshipu Mister: so as many positions as your ADC's resolution
16:18 Mister deshipu: let me see if i understood corectly.. :-P if i control a servo and an anctuator at the same time with the same circuit, then max and minimum will be the same as the servos potentiometer?
16:19 Mister on the actuator?
16:19 deshipu what do you mean 'a servo and an actuator'?
16:19 deshipu a servo is an actuator
16:20 deshipu a servo has a potentiometer inside which it uses to determine whether it shold move left or right from its current position to get to the position you set
16:21 deshipu you can read that potentiometer's value to know in what position it is right now
16:22 deshipu the signal is different, of course -- a servo uses PPA (or you can simulate it with PWM), the potentiometer will give you an analog reading
16:23 deshipu so you have to map one to the other in software
16:23 Mister aha k, is there any actuators without this sensor? i thought that was the part that defined a servo x-D
16:23 deshipu there are robotics servos that use more sophisticated sensors, like encoders
16:24 Mister encoders? as in text?
16:24 Mister instead of looking at the resistance?
16:25 deshipu as in gray code or something
16:26 deshipu https://en.wikipedia.org/wiki/Rotary_encoder
16:28 Mister that is very very interestting.. =)
16:28 Mister interesting*
17:01 deshipu http://ftp.ccc.de/congress/31C3/h264-hd/31c3-6077-en-How_I_Learned_to_Stop_Reinventing_and_Love_the_Wheels_hd.mp4 <-- about ROS
17:11 Mister is there a name for electrical motors that is formed as a cd? that sins the top like a picca plate x-D
17:11 Mister pizza*
17:12 Mister or servos i meen
17:13 Tom_itx pancake motors
17:13 deshipu or disc motors
17:15 Mister aha cool Thanx! =)
17:15 Mister deshipu: i'm not 100% certain, but i tihnk einstain said this "everything that can be invented has already been invented we are merely reinventing them"
17:16 Mister think*
17:16 Mister einstein*
17:16 acetoline it definitely wasn't einstein
17:16 acetoline einstein would never say something like that
17:17 deshipu nihil novi sub sole
17:17 acetoline it was probably Henry Ellsworth who said it
17:18 Mister but i understand the pweon who said it..:-P there are many things i have thought of, and you to, that will not become a standard
17:18 acetoline I think it's more accurate to say that big breakthroughs are rare
17:18 Mister and inventions are just a way to do a job x-D
17:18 acetoline most 'inventions' are just incremental improvements
17:19 deshipu Mister: that's why you need to do your basic research before you start inventing things
17:19 Mister but if darwin is correct, then humans evolve and become smarter, wich meens that we will find quicker ways to do work
17:20 deshipu Mister: and usually you do it either at the borders of current knowledge, or at the connections between different fields
17:20 Mister deshipu: my first invetion was a joke. =)
17:20 deshipu Mister: Darwin was greatly simplifying
17:20 deshipu Mister: we now have a much better idea about how evolution works (and a much better idea about the parts that we don't know)
17:21 deshipu the more you know, the more holes in the knowledge you discover
17:21 Mister hmm very intersting words
17:21 deshipu and the more complex the subject becomes
17:21 Mister i like to say: the more you learn, the more you learn that we don't konw anything.
17:21 Mister know*
17:22 deshipu that's why people who know very little about a topic often think that it's simple and easy
17:22 deshipu but that's fine, if they knew how complex it is, they woul never have the courage to try to learn it
17:24 Mister i also like to say that everything you know, you konw because you asked a question at one point in time
17:24 Mister know*
17:24 Mister if you tell me something, then it won't matter unless i ask to myself, "What is he spealing of?"
17:25 deshipu spealing?
17:25 deshipu ah, speaking
17:25 deshipu well, most people learn best by solving actual problems that they have
17:25 Mister one must reach out and grab whatever is given to you, or it'll fall to the ground right in front of your feet
17:26 Mister hmm i agree x-D
17:26 Mister that was what i ment by asking questions, to suddenly feel the urge to know how to solve the problem
17:40 Mister deshipu: can rotary encoders do more the one rotation?
17:40 Mister maybe they are used in disk servos?
17:40 deshipu usually
17:40 Mister hmm cool
17:40 Loshki SLAM for dummies is too hard for me. Where is SLAM for dummies for idiots?
17:40 deshipu maybe try SMASH instead ;)
17:40 deshipu even Hulk can do it
17:41 Loshki SMASH collision avoidance systems? It has a ring to it...
17:41 deshipu aka "no avoidance, just more power" ;)
17:42 deshipu a real robot for your world domination army shouldn't care for any obstacles
17:43 Loshki Step 1) vacuum the apartment. Step 2) engineering Step 3) world domination Step 4) Profit!
17:47 Mister guys.. i'm wondering something..
17:47 Mister in math, ther are variables, like x=3
17:48 Mister on this site there are equations with these special symbols, P and all that thing that looks like E
17:48 Mister http://en.wikipedia.org/wiki/Simultaneous_localization_and_mapping
17:49 Mister Why does no1 use more then 1 symbol in their variables?
17:49 deshipu tradition
17:49 Mister using 1 symbol limits us to the alphabet's maximum number
17:49 deshipu also, Sigma is not a variable, it's a symbol for a sum
17:50 deshipu Mister: sure, but then you can smash multiple symbols together to multiply them without having to write × ;)
17:51 deshipu also, historically, all the mathematicians invented their own symbols anyways
17:51 deshipu many theories were developed independently without the authors knowing it, just because the symbols were different
17:52 Mister that's what i was thinking, the latin symbol (and most other text systems) are a form of "self.programming" drawing of a symbol
17:52 deshipu Mister: mathematicians think on paper, to a large extent, so it's important to be able to write fast
17:53 Mister mandarin has 1 symbol for a whole sentence i tihnk, or word
17:53 deshipu for a concept
17:53 deshipu not whole sentence, no
17:53 Mister a word is like a shineese symbol x-D
17:54 deshipu and you can write that phonetically too
17:54 Mister chineese write in all directions, we only right from left to right
17:54 Mister mandarin*
17:54 deshipu no, they only write top-to-bottom, right-to-left and left-to-right
17:55 deshipu the latter being copied from latin, actually
17:55 Mister i ment the words, that consists of 1 symbol
17:56 Mister they can make line in all directions and the lines meens something
17:56 deshipu top-to-bottom makes sense if you consider that for a long time they wrote with right hand holding a brush with ink, and the ink needs time to dry
17:56 Mister like "L" is 2 lines, and "H" is 3 lines
17:56 Mister HI is 4 lines
17:56 deshipu the directions of drawing those lines are strictly defined
17:56 deshipu also the order
17:56 Mister and hi is a word =)
17:56 deshipu in Chinese, I mean
17:57 deshipu Mister: if you write it with a pen, you can make it one wiggly line
17:57 Mister hehe true
17:57 Mister it's alot more dynamic that way it seems
17:59 deshipu Loshki: by the way, maybe this will help? http://nbviewer.ipython.org/github/CamDavidsonPilon/Probabilistic-Programming-and-Bayesian-Methods-for-Hackers/tree/master/
18:01 Loshki deshipu: thanks. It will make nice holiday reading!
18:06 Mister deshipu: i think this formula is easier to understand, and meens the same, but takes more storage space on the HDD: (Energy of an object) = ((Mass of object) X (speed of light in vacuum)) X (it self)
18:06 Mister easier then e=mc2
18:06 deshipu it's E=mc²
18:06 deshipu the case and index are important
18:06 Mister no idea how to make that symbol :-P
18:07 deshipu also, it doesn't really mean the same thing universally
18:07 deshipu Einstein had to actually define what E, m and c meant in the text
18:08 deshipu that's the whole idea of using symbols, you define them, and then you can use them as shortcuts
18:08 Mister but then you do math in code words :-S
18:09 Mister it is hard enough to use code words when not doing equations
18:09 Mister a machine should use as few symbols as possible, i agree, but that is to save energy
18:09 Mister and time
18:10 Mister instead of "int main[]()" i would write "integer variable main ()()"
18:11 Mister in c++
18:14 Mister or like this: "integer variable main (variable 1, variable 2)( function 1, function 2) function 1= while variable 1 < 2 do fundtion 2
18:14 Mister function 2= print "hello world"
18:16 rue_shop4 oh no, there's a ramp laying in the pond, the fish will get out!
18:17 rue_shop4 I dont see any in there, maybe they already did
18:17 Mister it's the dolphins i know it
18:18 Mister they are saving their friends before they enslave the humans
18:19 rue_shop4 hmmm
18:22 deshipu Mister: it doesn't matter, because to understand the math, you have to read the full text anyways
18:23 deshipu Mister: math equations are not code, they don't "work" on their own
18:32 Mister but you would only need to learn one code language
18:32 Mister and add codes to that if you are missing a word for an object
18:32 Mister like i was missing th eword for disk servo
18:33 Mister word*
18:34 Mister instead of refering to "the speed of light" we should speak og it as C, or vice verse
18:35 Mister i'm working on that btw x-D a new kind of code language constructor
18:35 Mister where you can make a "command"
18:35 Mister a command consists of static and dynamic links
18:36 Mister if you wanted to make your own code for "int main[]()" it would be something like static-dynamic-static-dynamic-static
18:38 Mister first static text is "int main [ " and second is a dynamic link like a hypertext link that opens a text editor so you can add a value
18:38 Mister second static would be " ]( "
18:38 rue_shop4 I thought C was capacitance
18:39 rue_shop4 in liters-beer/hr
18:39 deshipu battery rating
18:41 rue_shop4 your right C is charge rate
18:41 Mister your code could look like " declair local variable (dynamic name) so functions (dynamic link) for main variable"
18:41 deshipu Mister: it's much easier to just read it English, seriously
18:41 rue_shop4 so in conclusion, if everyone used C, nobody would know what anyone was talking about anymore
18:42 Mister if you want to add a new language you can click a button and add the command for that language
18:42 rue_shop4 and people would start mixing things for different C's
18:42 deshipu and C++ would be born
18:42 Mister the "mother language" is the one you have to make your self
18:42 rue_shop4 and before you know it, people would be injecting liters-beer/hr into batteries
18:42 Mister deshipu: i'm gonna make a norwegian language x-D
18:43 deshipu math is hard enough without inventing your own languages, really
18:43 Mister but it can be translated with a autotranslater
18:43 rue_shop4 like I'v ever seen anything 'auto' in my life ever work
18:43 deshipu no, it can't, because you still need the definitions
18:44 Mister or you can make an autotranslator yourself (it's made for making your own languages and binding the codes to eachother
18:44 Mister inside the program
18:44 Mister you can decide if you want to print the text as c++, php, english or whatever language you have made =)
18:44 Mister codes for*
18:45 deshipu there is a special hell for people who invent their own languages and start all their programs with small interpreters for them
18:45 Mister lol
18:45 Mister it won't run from that program x-D
18:46 Mister you make a program there, then u can open a text file in programs liek processor or visual studio
18:46 Mister like*
18:46 deshipu anyways, good night
18:47 Mister nn^^
19:05 Mister rue_shop4, i think the program is gonna be called CC or Central Command, but it's more like a code archive then a language
19:06 Mister where you can add c++ codes and php
19:06 Mister and the c++ language can then be turned into php by a click of a button
19:08 Triffid_Hunter have you seen emscripten? uses llvm to compile C or C++ and spits out javascript
19:08 Triffid_Hunter I'm sure you could do php the same way
19:29 armyofevilrobots rue_shop4: http://lifehacker.com/307756/how-to-make-a-beer-battery
19:34 rue_shop4 oh deer
19:54 Loshki deshipu: "there is a special hell..."++
20:09 Hyratel what can I do with a Cypress PSoC 4245 prototyping kit? They're $4/each, and one came in the 2015 FRC KOP
20:12 Mister Triffid_Hunter, hmm cool i'll check that out
20:12 Mister doesn't all servos have 3 wires?
20:13 Hyratel Mister, only PWM drive ones
20:13 Hyratel there's also I2C servos
20:13 Mister how do you tell what position you want to have it in?
20:13 Mister is there's only 2 wires
20:14 Mister freequency?
20:14 Hyratel 4 wire is I2c
20:14 Mister aha
20:14 LoRez you need at least 3 wires to a servo. power, ground, comms
20:15 Mister aha k
20:15 Mister so this isn't really a servo? http://www.ebay.com/itm/Yaskawa-Minertia-P09E-DN21-Electric-Disc-Armature-DC-Servo-Motor-P-Series-9-/151537588393?pt=LH_DefaultDomain_0&hash=item23485818a9
20:15 Mister maybe just a part of one?
20:19 rue_shop4 ist just a motor
20:19 rue_shop4 they put the word servo on it to help it sell
20:19 rue_shop4 they like putting hot words on things they sell
20:20 rue_shop4 I'm surprised they didn't put arduino on it
20:20 Hyratel yeah that's just a DC gearmotor
20:20 rue_shop4 $36 chipping, hah, you would think it was comming from the usa
20:21 Mister it could look lkke it's made for mounting a sensor on it tho, does people usualy do that?
20:21 Hyratel you can make a 'servo" with it by slaving a potentiometer to the output shaft and putting a closed loop control on it
20:21 Jak_o_Shadows ok, stuff trying to fix the am radio tuner
20:21 Jak_o_Shadows all the string has come out
20:22 rue_shop4 pretty sure there is no way on this planet that thing it worth $61
20:22 rue_shop4 Jak_o_Shadows, haha, need to restring it eh?
20:22 Jak_o_Shadows yup.
20:22 Jak_o_Shadows I was trying to manually tune it, but I don't think just twisting it was giving me enough resolution
20:24 rue_shop4 hah it is from the states
20:24 rue_shop4 no, I'd not even pay $5 for that motor
20:25 Mister i was just wondering is there was some kind of technology i dind't know about :-P
20:25 Mister they called it a servo and it had 2 wires
20:26 rue_shop4 its not a servomotor
20:26 rue_shop4 its not even close
20:27 Mister that is what i was suspecting :-P
20:27 rue_shop4 you didn't buy it did you?
20:28 Mister nop x-D
20:29 Mister but i was thinking of switching the potentiometer with an accelerometer mounted on the moving part
20:29 Mister if acceleration controlls the speed and direction of the motor it'll work the same way
20:29 Mister controls*
20:30 Mister or gyro or both
20:30 rue_shop4 http://ruemohr.org/~ircjunk/robots/arm5/p1030724.jpg
20:30 rue_shop4 this one has potentiometers on the joints
20:31 Mister aha very interesting!
20:31 rue_shop4 apparently the better pictures weren't posted
20:31 Mister have you seen it in action?
20:31 Mister or made it? x-D
20:31 rue_shop4 I was one of the makers
20:32 Mister cool =)
20:32 rue_shop4 it was mostly made by one of my robotics students
20:32 Mister how is the stability with those potiensometers?
20:32 Mister are you a teacher?
20:32 rue_shop4 due to a lot of things its awefull, but the program eventually gets the arm to where it wants it
20:33 rue_shop4 kinda
20:33 rue_shop4 I'm just some guy who knows stuff
20:35 Mister what was it made for?
20:35 Mister making circuit boards?
20:36 Mister hmm but you teach students at a school?
20:39 tws2172 hello
20:48 Mister very cool arm btw, rue_shop4
20:49 rue_shop4 what about arm 6, 7, 8, and 9?
20:52 armyofevilrobots cortex joke in 5..4..3..2..1..
20:52 rue_shop4 :/
20:53 rue_shop4 yesterday I got some crisco
20:53 Tom_itx did it help?
20:53 rue_shop4 I'm still to mad at the machine to set it up again right yet
20:54 choonway lol. not_public_dont_open is as good as "don't press the red button"
20:55 rue_shop4 :)
21:13 armyofevilrobots rue_shop4: Feeling better yet?
21:43 tws2172 hello
21:43 ace4016 hi
21:45 tws2172 still playing Kerbal?
21:47 ace4016 no idea
21:47 ace4016 Hyratel, still playing ksp? :P
21:49 Hyratel yeah why
21:49 ace4016 tws2172 wanted to know for some reason
21:59 ace4016 tws2172, any cool projects you're working on?
22:03 tws2172 training some Haar cascade classifiers
22:04 GuShH rue_shop4: Hmm I didn't know this but the toothed / low pulley on the china lathe has a ball clutch, explains the play on the whole thing.
22:05 GuShH the shaft is eccentric so you can adjust the belt tension, but I think too much oil got inside the clutch and that's why it was giving me trouble.
22:05 Tom_itx tighten it's balls
22:05 GuShH you can't on this design it uses 6 springs, 6 balls and a circlip
22:05 GuShH with a retainer / washer
22:06 GuShH design flaw: they didn't sleeve the aluminum pulley with bronze
22:06 GuShH only the inner shaft of the clutch is sleeved
22:07 GuShH Tom_itx: could be the springs are getting tired though, if you replaced them with harder springs you'd get a stronger action, but also more likelyhood of a nasty crash
22:07 GuShH at least this thing will slip saving -in theory- the belts and gears
22:07 GuShH I hardly ever use the low pulley at all though
22:13 Hyratel so, hardware heads - what *IS* a PSoC? Is it a bundle of peripherals, a CPU and hardware logic glue?
22:15 rue_shop4 most motherbaords are small enough that it dos't matter
22:43 Mister anyone know where to buy fast and cheap linear actuators?
22:46 ace4016 i use to have a link...
22:46 ace4016 also, what's considered fast and cheap?
22:47 Mister hmm max to minimum in under 2 seconds?
22:47 Mister is that possible witohut usind some kind of chain?
22:47 Mister using*
22:50 Mister under specifications on this one it says sppeed: 1" (2.5" no load), does that meen 1 inch per second?
22:50 Mister http://www.firgelliauto.com/products/heavy-duty-track-actuator
23:01 GuShH https://www.youtube.com/watch?v=uzO2mi4uHAs
23:02 ShH tips
23:02 GuShH Tom_itx: clutch working fine now, yey.
23:09 GuShH it had 5 springs not 6 :( http://i.imgur.com/QZM3X7B.jpg and one of the circlips wasn't tempered properly, lawl.
23:10 Hyratel the small circlip?
23:10 GuShH nasty amount of oil and poop that came out
23:10 GuShH yerp
23:10 Hyratel this is .. a spring detent clutch?
23:11 GuShH I call them ball/lock clutches, china says it's a safety device, you may call them spring detent clutches!
23:12 Hyratel I just describe what they consist of, verbosely
23:13 GuShH they're similar if not the same as ball bearing lock-up clutches
23:13 GuShH I think it could use stronger springs
23:15 Hyratel hmmm
23:16 orlock Hmmm.
23:16 GuShH The idea is not to use it
23:16 GuShH but if it slips under low torque, it becomes an issue
23:16 orlock I've got a 3 wire optical sensor, the sensor itself is 4 pins
23:16 orlock anode and cathode for LED, and collector emitter for sensor
23:16 orlock cathode and emitter are wired together on the PCB
23:17 GuShH so?, it uses a common ground
23:17 Hyratel I've got this PSoC and it has one protostick LED, not unlike the arduiono's p13 LED. it did not come with headers installed and i'm hesitant to put some on it, mainly because it'd be a royal pain to stick down onto a solderless breadboard like that. but I also don'thave stackable headers, nor female header-strips long enough
23:17 Hyratel advice?
23:17 GuShH buy sum
23:18 Hyratel no has moneys
23:18 GuShH cant has headers
23:18 Jak_o_Shadows Is there such a thing as double ended male headers? Like you could use for plugging servos into a breadboard?
23:18 Hyratel should I just go ahead and put the male/down headers on it and stick it in a solderless?
23:18 GuShH yes
23:18 GuShH I got a bunch from sure-electronics a while back
23:18 orlock GuShH: thats what i thought, then +ve to anode and the sensor collector should give me what? a 0-5v signal, or should i be measuring resistance?
23:18 GuShH also females, males, etc.
23:19 Hyratel yes there are. i have some but not enough for the whole protostick
23:19 GuShH brb gotta apply some bondo
23:19 GuShH 2AM and it's cold outside, but it must be done.
23:19 Jak_o_Shadows Is there a name for them (is perhaps my question) ?
23:20 rue_house is that a crab?
23:21 rue_house oh I guess it is
23:29 Mister is this motor anything some1 would recomend for a small self-balansing vehicle?
23:29 Mister http://www.ebay.com/itm/Razor-MX500-Dirt-Rocket-Bike-Electric-Scooter-Motor-36V-500W-MY1020-H-ST20-/161308540843?pt=Motors_ATV_Parts_Accessories&hash=item258ebcffab&vxp=mtr
23:31 rue_house not at that price
23:34 Hyratel Mister, person or only self payload?
23:35 Hyratel http://www.andymark.com/CIM-motor-FIRST-p/am-0255.htm
23:35 Mister very little payload
23:35 Hyratel if it's less than 60 lbs all-vehicle, you don't even need motors that^ big
23:37 Mister hmm probably around that weight, not sure rly :-S
23:38 Hyratel the motor I linked is 12v half horsepower
23:39 Mister think that motor would work in an actuator too?
23:39 Hyratel wwhat kind of actuator
23:39 Mister similar to this one http://www.youtube.com/watch?v=HN1xSIgnwDA
23:39 Mister around 1.5meter long
23:39 Mister long*
23:40 Hyratel it's a 4500 RPM motor
23:41 Mister it must be as fast as possible x-D
23:41 tws2172 http://dartactuators.com/
23:41 Mister gonna make a prototype of this camerastand in wood
23:42 Mister Tiundra-telebotics.com
23:43 Mister hmm think i need 1.5meters pers second or something
23:43 Mister gonna try with a chain and a powerful engine
23:46 tws2172 a CIM motor would be fine for that
23:47 Mister hmm cool Thanx for the info btw =)
