<GorDonFreeMan> and engraving/milling some glass
<GorDonFreeMan> milling some plexiglass sheet, wood, plastic, aluminium, steel
<GorDonFreeMan> i'll stay below 2kW this year i think
<GorDonFreeMan> not a 10kW milling machine
<GorDonFreeMan> but i'm only movind a dvd main drive motor now
<GorDonFreeMan> haha ok
<GorDonFreeMan> yeah well i can do that in openloop mode, but what if my servo does not have "steps" ?
<GorDonFreeMan> ;/
<GorDonFreeMan> yes
<GorDonFreeMan> i have a linear motion in 3 axis
<GorDonFreeMan> so what do you suggest for position sensing?
<GorDonFreeMan> somebody building CNC machine here?
<GorDonFreeMan> and they usually can handle 500-800mA
<GorDonFreeMan> 96 full steps
<GorDonFreeMan> i have even found 96 step steppers in printers :)
<GorDonFreeMan> sooo
<GorDonFreeMan> ahaha
<blogic> GorDonFreeMan: accoring to you url the budapest IX runs a pr0n site from which you connect
<GorDonFreeMan> *laser
<GorDonFreeMan> laster printers have ultra cool stepper motors
<GorDonFreeMan> :)
<GorDonFreeMan> som printers
<GorDonFreeMan> also bad HDD-s
<GorDonFreeMan> just have to find some
<GorDonFreeMan> so there are many thrown out junk dvd players around here
<GorDonFreeMan> EU
<GorDonFreeMan> hungary
<GorDonFreeMan> i just always have beter things to do
<GorDonFreeMan> but i could
<GorDonFreeMan> i haven't made a blog
<GorDonFreeMan> or... i could do that, if i enclose my stuff dust-free
<GorDonFreeMan> i don't want encoder foil and photo diodes
<GorDonFreeMan> ;/
<GorDonFreeMan> and i'd need some type of industrial dirt-safe position encoder
<GorDonFreeMan> i have a motion
<GorDonFreeMan> sooo
<GorDonFreeMan> :)
<GorDonFreeMan> so i'm making prototype
<GorDonFreeMan> no, i just thinked this out about 30 mins ago
<blogic> GorDonFreeMan: do you have pics online ?
<GorDonFreeMan> still have to decide the feedback type
<GorDonFreeMan> :)
<GorDonFreeMan> and i think i will consider my beta test robot muscle
<GorDonFreeMan> so you have to make servos first.
<GorDonFreeMan> but you want cheap servos in your robots
<GorDonFreeMan> haha
<GorDonFreeMan> design servos, and make them :P
<GorDonFreeMan> but the time needed would be large
<GorDonFreeMan> a cd drive can move 1 tonn robot
<GorDonFreeMan> :P
<GorDonFreeMan> or.... it will be slow
<GorDonFreeMan> blogic<< large scale will be expensive whatever you do
<GorDonFreeMan> and the main drive motor can even fly an aeroplane if properly hacked
<GorDonFreeMan> cd drives have little steppers that you can use for a spider:P
<GorDonFreeMan> ;>>
<GorDonFreeMan> :P
<GorDonFreeMan> and extract steppers from junk
<GorDonFreeMan> no, i build mine
<GorDonFreeMan> ;/
<GorDonFreeMan> i don't like pressure things
<GorDonFreeMan> i have more designs for more applications
<GorDonFreeMan> stepper motors, and magnetic magic :)
<GorDonFreeMan> now deciding what i use it first :)
<blogic> GorDonFreeMan: how ?
<GorDonFreeMan> yea
<GorDonFreeMan> <;
<GorDonFreeMan> i have just designed a robot muscle
<GorDonFreeMan> :)
<GorDonFreeMan> i like quality too
<GorDonFreeMan> ;>
<GorDonFreeMan> do you want to build speakers?
<wolfspraul> GorDonFreeMan: please keep us posted here, by all means
<GorDonFreeMan> it was 90cm high btw :) and had a reflex system
<GorDonFreeMan> i'll make another set in a few month
<GorDonFreeMan> and i didn't made it waterproof
<GorDonFreeMan> i got some liquid spilled on them
<GorDonFreeMan> well moisture killed my wood ;<
<GorDonFreeMan> and it was cool for many years
<GorDonFreeMan> i have built 2 huge speakers in 2001
<GorDonFreeMan> don't give a fuck
<wolfspraul> GorDonFreeMan: well really, please do it1
<GorDonFreeMan> it IS a speaker
<GorDonFreeMan> ;>>
<GorDonFreeMan> just connect the head to something at the center of rotation's angle with some rubber band, and attach a plate to it so it moves more air, then find the voice-coil's 2 endpoints, and connect an audio amplifier
<GorDonFreeMan> ahaha but it's simple
<wolfspraul> GorDonFreeMan: haven't heard of such a hack - but go ahead! ;-)
<GorDonFreeMan> you can even make a speaker from da "voice coil"
<GorDonFreeMan> i see some very c00l stuff in them
<GorDonFreeMan> anybody ever hacked a HDD ?
<GorDonFreeMan> ;>>
<GorDonFreeMan> hi

<GordonFreeman> why do i bother;/
<GordonFreeman> 061324] <maguoji> the file Makefile is created from Makefile.in?
<GordonFreeman> [061415] <maguoji> but the file Makefile.in is very simple
<GordonFreeman> [061409] <GordonFreeman> like any normal linux software
<GordonFreeman> [061350] <GordonFreeman> ./configure
<GordonFreeman> sure it does not protect against that
<GordonFreeman> scriptable.
<GordonFreeman> imagemagick can convert
<GordonFreeman> inkscape
<GordonFreeman> imagemagick
<GordonFreeman> even if they are good programmers
<GordonFreeman> i believe most pcb software are crap because programmers don't design pcbs
<GordonFreeman> roh<< a user does not even have to know anything about programming
<roh> GordonFreeman: you have to read the last sentence in a 'in soviet russia'-voice *veg*
<wpwrak> GordonFreeman: i've contributed some small things over the years. e.g., the "magnetic" pads and traces
<GordonFreeman> no, a user is a user
<roh> GordonFreeman: on opensource every real user is a dev ;)
<GordonFreeman> wpwrak<< are you kicad dev?
<GordonFreeman> and it would need additional logic
<GordonFreeman> it only has minor lolnesses, like i had to hack the scroll directions
<GordonFreeman> btw x-fig was almost usable as a schematic designer
<GordonFreeman> i'd never start using some junk
<GordonFreeman> probably coder electronic engineers don't use linux, and don't write pcb editors
<GordonFreeman> and there is that "PCB" named thing, but still unusable
<GordonFreeman> tried kicad like 1 years ago, and it was crap then
<GordonFreeman> aha i see
<roh> GordonFreeman: nope. but its avail for linux
<GordonFreeman> eagle is opensource now?
<wpwrak> GordonFreeman: kicad's pcbnew is pretty decent. just lacks a push router.
* GordonFreeman wondering why there isn't any non crap pcb editor for linux

<blogic> GordonFreeman: no whitespace error highlighting :)
<GordonFreeman> blogic<< f9 compile, f5 run, syntax highlight, automatic tooltips/code-completion rulz
<GordonFreeman> power users like comfort if they do actual work i guess
<GordonFreeman> you deserve that nick ;>>>
<GordonFreeman> blogic<< btw, come to #theblackmatrix and kick logic
<GordonFreeman> feel free to give ideas for alternative input methods
<GordonFreeman> but if you have to draw a pcb then it is more user-friendly than no mouse
<GordonFreeman> sometimes
<GordonFreeman> do not want
<GordonFreeman> lold
<GordonFreeman> :quit to quit ?
<GordonFreeman> yes
<GordonFreeman> *hate
<GordonFreeman> i have it because it's not user friendly
<GordonFreeman> recently changed the tab to spaces so it will be the same in mc f4 now
<GordonFreeman> i use geany btw
<GordonFreeman> but i came from assembly
<GordonFreeman> working on that ;>>
<blogic> GordonFreeman: i see you dont like indenting :D
<GordonFreeman> uses HRT
<GordonFreeman> some SDL example for linux
<GordonFreeman> they'll have a concurrency
<GordonFreeman> no <;
<GordonFreeman> i'm not telling secret if i say it will have fractal components
<GordonFreeman> i design pcb-s too btw, so i'd like to make it comfortable
<GordonFreeman> wpwrak<< but if you have problems in general i may never let happen them in my software
<GordonFreeman> i'm writing the primitives rendering an core functions currently...
<blogic> GordonFreeman: link ?
* GordonFreeman is Godlike
* GordonFreeman is Dominating
<GordonFreeman> i am writing a pcb editor software for linux so i'd be interested in your problem
<GordonFreeman> you can extend it to any number of resistors ;>
<GordonFreeman> i can tell you a quickhack function for resistor and capacitor networks, it's called the "Replus" operator, R_e=1/((1/R1)+(1/R2))
<GordonFreeman> i see, then why are you concerned about values if it needs +-50% precision?:
<GordonFreeman> i never bought resistors >10% precision in smd
<qi-bot> wpwrak meant: "GordonFreeman: of course, they may still have simply found it cheaper to use a 560k 1% than a 560k 5%"
<wpwrak> GordonFreeman: of course, they may still have simply find it cheaper to use a 560k 1% than a 560k 5%
<wpwrak> GordonFreeman: yes, but that seems to be the kind of circuit where they design with +/- 50% ;-)
<GordonFreeman> 4 digit is not rare btw, i use them often, they have 1% or more precision in general
<GordonFreeman> you know, linear equations
<GordonFreeman> matrix multiply it
<GordonFreeman> btw you need insane amount of powwer to vaporize the copper with any laser that will be $10k$+
<GordonFreeman> its silly to just aim $1000+ lasers onto an approximate spot
<GordonFreeman> how would you combine the laser beams into one line ? that is preferrably the possible thinnest line
<GordonFreeman> no.
<GordonFreeman> its only eye hazard
<GordonFreeman> nor pcbbbs
<GordonFreeman> but i see no real use of it yet.... too little power. i cannot cut steel with it
<GordonFreeman> must be fun shooting through 10 dvd cases with it
<GordonFreeman> ok i have seen blu-ray laser videos on youtube
<GordonFreeman> :) i like eficient hacks
<GordonFreeman> also it would take much more time
<GordonFreeman> i don't think so
<GordonFreeman> actually i'm building 3 axis cnc milling machine
<GordonFreeman> well, make a film, and shine lighht through it.
<GordonFreeman> i can do photolithography btw
<GordonFreeman> i don't do lol
<wpwrak> GordonFreeman: if you can also figure out how to move the laser, and how to control it, then you'd have a nice photoplotter
<GordonFreeman> so, i have removed the unnecessary stuff from the mainboard with a screwdriver, then cut some track on pcb, and reconnected the motor controller ic with cat-5e wires, and added a potentiometer for analog input control for the ic, and it works off a single 12V supply because i added a 7805 stab ic to generate 5V for it
<GordonFreeman> pics of my hacked dvd drive

<GordonFreeman> well i reserve the right to choose another random nick at any random time ;>
<DocScrutinizer> hmm, GordonFreeman ? we got a freemangordon in #maemo-ssu :-D

<GordonFreeman> and those nice silver-steel shafts mmm
<GordonFreeman> but i'm building CNC machine with 3 axis, and i use stepper motors from scrap printers
<GordonFreeman> so, the main drive motor, and the driving electronics
<GordonFreeman> only the miling machine, it does not have axes yet :)
<wpwrak> GordonFreeman: wow. just one DVD drive ? for how many axes ?
<GordonFreeman> i have just made a milling machine outof a scrap dvd drive, it turns an 1mm diameter diamond milling bit at variable RPM, i have cut a cd in half with it as test
<GordonFreeman> hi
