<zhangyi>
xiangfu: and try to follow the steps one by one and see where this leads me to
<xiangfu>
zhangyi: hi
<zhangyi>
xiangfu: hi
<zhangyi>
xiangfu: for OpenWrt distribution, should i just install tarball instead?
<zhangyi>
xiangfu: xburst-tools tarball
<wpwrak>
wolfspraul: any ideas for my HTML in git problem ?
<wpwrak>
wolfspraul: that's the last missing bit to complete the migration of the scans
<rafa>
kristianpaul: yes, but these are just test. but yes, with a specific way to convert the files I get fluency (after several seconds) but no sync
<wolfspraul>
wpwrak: I saw it
<wpwrak>
wolfspraul: somewhat tricky :) i tried to find out where the pretty-printing happens in the scm-to-git gateway, but could only find the decision whether to highlight or not
<wolfspraul>
wpwrak: hmm, since you already look in the indefero sources you are ahead
<wolfspraul>
we can just patch them
<wolfspraul>
I can also try to track it down
<wolfspraul>
there may be security implications, not sure. I'm always extremely careful with this html stuff, it's so easy to open some door without realizing..
<wolfspraul>
there seems to be a /file/ url to 'download' just the html, did you see that (at the bottom)
<wolfspraul>
we'll find a way. we could also ask on the indefero side, or file a bug/feature request to see what they say
<wpwrak>
(file URL) oh ! no, i had not spotted this one. let's see ...
<wpwrak>
hmm. very very close. konqueror asks what to do, then i tell it to just display it, and henceforth it does. firefox is less certain. it identifies it as html, but then offers me download or to run konqueror (!) to display it
<wpwrak>
i see basically three possible approaches: 1) put the file elsewhere, on some regular web space. quick and easy. drawbacks: view spans multiple sites, and relative paths don't work. so one can't just look at it locally, then commit. (except with a separate local build mode)
<wolfspraul>
I can look into this, an integrated solution would be best.
<wpwrak>
2) hack indefero to present the file as true html (or get it hacked). this should of course be optional - most people probably prefer to see html sources as text, without interpretation.
<wolfspraul>
the best would be if the indefero people could think it through :-)
<wpwrak>
3) do some url rewriting that maps everything into the same hierarchy, even if they're at different places on the server. a bit messy. basically moves the complexity of the "local build mode" into the web server
<wpwrak>
(indefero) agreed :-)
<wpwrak>
one could also consider this a completely different mode to view things. i.e., make it become a "regular" web server but using an scm instead of a regular file system
<wpwrak>
oh, if there was something like a gitfs, that would work too, in combination with a regular web server
<wpwrak>
googling for gitfs ... hmm, a semi-abandoned one from 2006 ...
<wpwrak>
... one on ithub, 2009,
<wpwrak>
... one on google code, for inferno, whatever os that may be, ... one for Pharao, whatever *that* may be, ... ah, and the semi-abandoned one even made it to lwn
<wolfspraul>
hah, once there was someone who said he wanted to port inferno to the nanonote :-)
<wolfspraul>
they ask to use the yahoo group first but I never figured how these groups work
<wolfspraul>
so let's see
<wolfspraul>
maybe I will also bring it up on the group
<wpwrak>
thanks ! btw, yahoo groups suck endlessly. even if you get them to work, you're asked for re-authentication for way too many things.
<rafa>
wpwrak: HA! firefox is smarter :) he wants konqueror to do the job while he is idle :)
<bartbes>
:P
<wpwrak>
hmm .. i have my mold for the counterweight. now, how do i cast ? make holes on the side and gravity cast ? or just fill the (flat) mold with a bit of molten solder and then close it with a flat surface, forcing the excess metal out ? tricky, tricky ...
<kristianpaul>
lekernel: it depends what you call like science
<kristianpaul>
is true there all stuff lacks freatures like you said so its a hacklab dint mean i cant improve
<tuxbrain>
argh, the soft of the microscope is written VB for win arrrg(again)
<kristianpaul>
i meant we're in the earlies of do science at home
<kristianpaul>
bbl
<wpwrak>
pour and tap doesn't seem to impress the metal much. pretty crappy results. pour and splash looks better, though. you also get a nice wave of molten led gushing out the mold and frozen in flight :)
<freespace>
you can do science experiemnts anywhere, you just can't do cutting edge science experiments
<freespace>
the average man has better equipment than any of the early scientists
<freespace>
and they without a doubt, did science
<kyak>
but early scientists had better equipment than any of the average man of that time
<kyak>
and so it remains now
<kyak>
+noone can work alone now.. the time of bright individuals has gone
<freespace>
for doing cutting edge experiments yes
<freespace>
science experiments include ones which has been done
<freespace>
not just limited to those requiring years of study to even understand the point of
<freespace>
and some of them don't even require anything more than a good telescope and patience
<freespace>
as for the time of the bright indivudal, that claim is dubious to me
<freespace>
it assuming that wisdom of the masses can over come indivudal genius
<freespace>
or make the same leaps of intutition
<kyak>
who needs to look for a before unknown comet, when you can buy one? :)
<freespace>
why buy one when you can look for one :)
<kyak>
yeah, but your life might be just not enough to find it :)
<freespace>
then surely that makes it more worthy than a piece of rock you buy :)
<freespace>
anyways, i dislike the idea the average mn can not do science
<freespace>
science is no more than the process of forming a hypothesis based on observation, then testing the hypothesis
<kyak>
indeed
<kyak>
the problem is that sometimes you need an handrom collider to test the hypothesis
<freespace>
and sometimes, you can just do thought experiments and change physics for ever :)
<kyak>
if you ever do something like this (as a private individual), please let me know ;)
<freespace>
i will do better, and let the world know :)
<freespace>
i am under no illusions i am that clever
<freespace>
einstein did it while working as a patent clerk
<freespace>
and a private individual, so it can be done and has been done
<freespace>
i would wager most ppl are not in a position to do research science not because of their lack of equipment
<freespace>
but their lack of education
<kyak>
things has changed since that, but now we are starting to go circles in our discussion and i have to go home :)
<kyak>
since that , i,e, since einstein
<freespace>
what has changed?
<freespace>
ok :)
<freespace>
good evening :)
<freespace>
assuming it is evning where you are
<kyak>
let's discuss later if you wish :)
<kyak>
evening it is
<freespace>
i will be asleep later
<freespace>
it is currently 14 minutes to midnight
<kyak>
good night then
<freespace>
have a good evening :)
<wolfspraul>
midnight?
<wolfspraul>
are in you Australia?
<wolfspraul>
I'm also calling it a day in China, but it's not midnight yet :-)
<freespace>
midnight in 3s
<freespace>
s/.$/m/
<freespace>
yeah
<freespace>
sydney :)
<freespace>
right, attempt to sleep before 2am #4
<freespace>
g'night
<wolfspraul>
n8
<lekernel>
<freespace> the average man has better equipment than any of the early scientists
<lekernel>
wrong
<lekernel>
I don't think anyone here has ever liquefied air
<lekernel>
still it has been done by early scientists in the late 19th century
<lekernel>
also, DIY triodes and other vacuum tubes is seldom heard of nowadays
<lekernel>
and it's not entirely because there are transistors... vacuum tubes have a few advantages over them typically for high power RF
<freespace>
anyone here can more easily liqufiy air than any early scientist
<lekernel>
oh, really?
<wpwrak>
tuxbrain_away: design weight 17.6725 g, measured weight 16.8 g. design thickness where thickest 2.4 mm, measured thickness about 2.6 mm. good enough.
<lekernel>
how would you do that then?
<lekernel>
i'd be happy to hear, making liquid nitrogen is cool (literally ;) )
<freespace>
have you ever operated a fridge?
<lekernel>
sure, but you're not going to liquefy air with a fridge compressor
<freespace>
so how did the early scientists do it?
<wpwrak>
lekernel: it all depends on your tolerances. e.g., it's easy to liquify a large percentage of really humid air :)
<lekernel>
with much powerful compressors
<freespace>
right, so first we need to get more powerful compressors
<lekernel>
fridge compressors are mass produced cheap industrial crap designed to fulfiil one function during a limited period of time
<freespace>
i wager the early scientsits couldn't hop down to the lcol hardware store and BUY one
<freespace>
Carl von Linde liquidfied air in 1895
<freespace>
are you seriously suggesting the average modern man has INFERIOR equipment to what he had access to
<lekernel>
I don't think you can buy a compressor to liquefy air today either
<freespace>
yes you can, fridges do it
<lekernel>
they'll overwhelm you with paperwork "you're not a company" "you're not authorized to do that" etc.
<lekernel>
from what I've read, access to scientific hardware was much easier back then
<freespace>
i don't think it was so much access, more the fct they had to build it
<freespace>
if you build it yourself, then access is retty good
<lekernel>
so, maybe big compressors for large cold rooms (ie industrial ones) might liquefy air
<lekernel>
but not your average household fridge's compressor
<freespace>
your average household compressor liquifies fases
<freespace>
*gases
<lekernel>
it liquefies a very special gas which is super easy to liquefy
<freespace>
so?
<lekernel>
I guess you can even do it with a bike pump
<lekernel>
air is a different thing
<freespace>
specify a very specific gas we need to liquidfy then
<lekernel>
a lot more pressure is needed
<freespace>
or a mixture thereof
<freespace>
all of this ignores the fact the average man can buy or ask for liquidfied air to do experiments with
<freespace>
unlike the early scientists who had to make their own
<freespace>
just think for a moment the kind of lenses one can order
<lekernel>
tried that, got rejected because they only ship to companies
<lekernel>
of course this can be worked around
<freespace>
they are grounded to such preceision that newton would give his left testicls for
<freespace>
your problem then isn't that the average man doesn't have better access to equipment
<freespace>
but the average man has to deal with more paper work :P
<lekernel>
sure, but that's still a problem that disconnects the average man from science
<freespace>
no, it disconnects the average man from buying large compressors
<freespace>
what disconnects the average mn from science isn't equopment
<freespace>
by far the biggest barrier to entry to science
<freespace>
is lack of education
<lekernel>
of course, if you count what companies and industry have access too, we sure have better equipment than in 1900
<freespace>
specifically mathematics
<lekernel>
but for what the average man can handle, I'm not so sure
<lekernel>
yeah, that's another one
<freespace>
you are only considering a very limited set of experiments
<freespace>
if your interest is in astronomy
<freespace>
then what you can buy for a few hundred dollars
<freespace>
is astronomically better
<freespace>
pardon the pun
<freespace>
by and large, modern science has moved forward by leaps and bounds
<freespace>
while science education hasn't
<freespace>
that the modern man feels disconnected from science is a sad reflection of the state of science education
<lekernel>
yeah, I agree with you that education is a problem too
<lekernel>
but the "leave that to the pros" culture is an obstacle too
<freespace>
you can always join the pros
<lekernel>
of course
<freespace>
and in many ways, you have to. the same way we leave brain surgery to brain surgeons
<lekernel>
but it requires a mental effort
<lekernel>
and a few social barriers to overcome
<lekernel>
plus once you've joined the pros, in many cases you usually have to do what your boss tells you to do
<freespace>
but not all the time
<freespace>
in my limited experience, your supervisor will have some direction you hsould follow
<freespace>
like in any other profession
<freespace>
you start off learning under your betters
<freespace>
if only in experience
<freespace>
hrm, perhaps you meant the average person can't make a contribution to science
<freespace>
in the sense contribute new and useful data
<lekernel>
that too
<lekernel>
and the difficulty of learning by yourself because a lot of devices are difficult to acquire
<freespace>
which i suppose has always been true for particle physics, but amartuer astronomers are doing well
<freespace>
that is why you do to university
<freespace>
learn with others, be taught by others, and work with equipment you won't otherwise have access to
<lekernel>
and imo there's a large cultural obstacle that's there without a really valid reason
<lekernel>
why should one be forbidden from ordering liquid nitrogen?
<lekernel>
or sulfuric acid?
<freespace>
or TNT?
<freespace>
they are all very dangerous materials
<zear>
or plutonium? Because it's potentially dangerous
<lekernel>
well then you can also forbid cars
<lekernel>
they can be used to run over people too
<freespace>
but cars a necessary
<zear>
not on such a scale
<freespace>
we balance risk against the benifits
<freespace>
if we take away knives say
<freespace>
life would become very inconvenient
<freespace>
so we trade off by allowing small knives to be frely available
<freespace>
but the really big ones regulated (in australia)
<freespace>
the average person generally speaing doesn't have a need for liquid nitrogen OR sulfuric acid
<freespace>
you can always form your own 1 man company
<freespace>
and order it via proxy
<freespace>
call it lekernel chemicals
<freespace>
:D
<lekernel>
thanks, I did that enough times already :)
<zear>
what some people do with everyday appliance things is enough to know allowing avarage person having nitrogen is dangerous
<freespace>
speaking of liquid nitrogen
<freespace>
attended a talk today by william d philip
<freespace>
nobel winner
<freespace>
he did wonderful liquid nitrogen demos
<freespace>
he splashed about a week's supply onto the stage
<freespace>
at one point, he filled a plastic bottle about half way with liquid nitrogen
<freespace>
then capped it
<freespace>
then left it under a plastic create
<freespace>
*crate
<freespace>
and kept going on with his talk
<freespace>
about 5min later
<freespace>
HUGE BANG
<freespace>
the thing exploded
<freespace>
pieces of plastic went everywhere
<freespace>
the crate that was meant to contain the explosion
<freespace>
also exploded
<lekernel>
I'm not even sure most average men would do such dangerous things should they easily buy ln2
<freespace>
it was great fun :D
<freespace>
the average man does such dangerou things with a bottle of coke and mentos
<lekernel>
just like most drivers don't run over people in the street
<lekernel>
that isn't really dangerous
<freespace>
it is if you were holding it at the time
<freespace>
i understand your frustration with regulation
<freespace>
but in some ways, the ease of access to dangerous materials "back in the days" was because we didn't know they were dangerous
<freespace>
people were taking RADIUM treatments
<freespace>
going in a room filled with radon gas
<freespace>
because they thought it was better for them
<freespace>
ppl drank mercury
<lekernel>
oh, and others, like phosphorus matches... sure, that was a factor too
<freespace>
to cure their illness
<lekernel>
but imo today there's too much safety theatre going on
<lekernel>
and this disconnects people from science
<wpwrak>
lekernel: of course, in the old times, you may not even have been among the small elite that had a rich man's ear and get their experiments sponsored ...
<freespace>
i doubt most ppl feel disconnected from science because they can't order dangerous chemicals
<freespace>
most ppl i imagine, feel disconnected form science b/c they don't know what is going on
<wpwrak>
lekernel: you'd just be a happy carpenter or so. completely untroubled by the difficulties of doing science :)
<lekernel>
freespace, it's a factor too I think
<freespace>
i mean, ppl won't say they are disconnected from their $sportteam becuse they can't play on the field with them
<lekernel>
safety + industrial secrets, ..
<freespace>
... unless they do
<freespace>
isn't a sports fan
<lekernel>
throwaway "no user serviceable parts inside" devices
<lekernel>
cars you need to send to the garage to change a light bulb because the manufacturer made it horribly difficult to access them (special screws etc.)
<lekernel>
etc. etc.
<lekernel>
there are a plethora of factors
<freespace>
some of that is progress
<freespace>
it isn't like we all have smd rework stations at home
<freespace>
and for all intents and purposes, modern electronics in the form factor we expect, really have no user servicable parts inside
<lekernel>
that's where hacklabs should come into play imo
<freespace>
it would be difficult to even user service the ben
<lekernel>
but you won't deny that a significant part of it is just sociocultural, right?
<freespace>
most of it is driven by profit
<freespace>
is that "sociiocultural"?
<lekernel>
that car manufacturer didn't _have_to_ put that wicked screw to open the light
<lekernel>
yeah, counts as sociocultural for me
<freespace>
you are saying thigns like that curtail curiosity or something?
<lekernel>
yes, that's exactly my point
<freespace>
but you have the internet
<freespace>
you have libraries
<freespace>
you have thigns like arduinos
<freespace>
a curious person has far more resources a their disposal now than any other time in history
<lekernel>
arduino is so small and boring compared to what the industry does
<freespace>
they are not restricted to breaking open the light in a badly made car
<freespace>
see, i disagree
<wpwrak>
freespace: (ben) you mean the mechanics ? that's largely a design problem. e.g., all the snap-in plastic is trouble, but a few screws would do just as well.
<lekernel>
plus it's just a proprietary chip with a nice wrapping
<freespace>
who cares?
<lekernel>
if they had made the AVR themselves and explained how to do so, then it would have been interesting
<freespace>
if you want to know how to build a cpu
<freespace>
google and digikey and amazon has everything you need to know
<freespace>
to build one from scratch using TTL level components
<freespace>
or even to build one using transistors
<freespace>
it would be a massive amount of effort
<freespace>
but certainly the information isn't locked away
<lekernel>
again, this approach doesn't cover a bastion of the industry: semiconductor manufacturing
<freespace>
if a curiouse person wanted to know how semiconducors are made
<freespace>
they can read about it
<freespace>
as for practicing it, one imagines you need a degree
<freespace>
before someone lets you near such a machine
<freespace>
you can always build one yourself
<freespace>
i suppose
<freespace>
the knowledge is there
<freespace>
and if you live near a beach, the raw ingridents
<lekernel>
not exactly there... most of it is secret
<freespace>
sure, bu the basics are the sme
<freespace>
and their secrets just make their semiconductors different
<freespace>
but they are still semiconductors
<lekernel>
look at all the effort the USA spent during the cold war to prevent the russian semiconductor industry from progressing
<lekernel>
even though they did have the basics
<freespace>
what efforts exactly?
<lekernel>
various embargos basically
<freespace>
i am aware of how much russians were copying us chip designs
<freespace>
but russia isn't exactly a country lacking in natural resources
<freespace>
and i imagine rather more factors than embargos of sand and such accounted for the state of development of the russian semi-conductor industry
<freespace>
their economic model and goernment probably had mor of a say
<freespace>
god i can't type when it is late
<lekernel>
if that development model was inherently screwed, why spend any effort on destroying it further?
<lekernel>
instead of letting it die by itself
<freespace>
because both sides were pointing nukes at each other?
<freespace>
and if your opponent had shittier electronics, that increases your chance of surviving a nuclear exchange
<freespace>
the suituation was, i gather, fairly complicated :)
<freespace>
it's been good talking to you lekernel :)
<freespace>
but suddenly it is 1:22am
<freespace>
and if i don't go now
<freespace>
i will have failed for the 4th time
<freespace>
to sleep before 2am
<lekernel>
ok, good night then
<freespace>
g'night again!
<freespace>
resume later if you wish :)
<kristoffer>
wolfgang?
<wpwrak>
kristoffer: i think he's already counting sheep
<kristoffer>
typical :)
<wpwrak>
kristoffer: always the same with those wolves :)
<ezdagor>
So there is absolutely no way to get a mouse working with the NN?
<zear>
there are ways
<zear>
sience got it working on dingux, so i guess we can do it on the nanonote
<ezdagor>
Ah.
<ezdagor>
I've tried various mouse emulators that remap the arrow keys to mouse movments... no luck.
<kristoffer>
wpwrak, the wolfgangs I know are either geniuses, weirdos or both
<kristoffer>
wolfgang... wake up
<wpwrak>
kristoffer: it's something like 4 am or 5 am in bejing :)
<kristoffer>
wpwrak, my point exactly, he should already have woken up, eaten breakfeast and started to work..:P
<wpwrak>
kristoffer: like any of his hard-working countrymen :)
<tuxbrain>
wpwrak, kristoffer_ you are cruel...:P
<rafa>
tuxbrain: that is because they are from Switzerland and Sweden
<tuxbrain>
hahahaha
<tuxbrain>
btw any progress with theora
<tuxbrain>
?
<tuxbrain>
I have just recived the songs and the image material to work with :)
<rafa>
tuxbrain: I was able to have audio and video fluent, bad quality, no sync
<tuxbrain>
mmm have you activate the sync option when encoding?
<bartbes>
who needs sync anyway? :P
<rafa>
tuxbrain: no idea, the problem looks when mplayer plays it. The sounds starts okey, but video no (no fluent), then after several seconds.. video goes well.
<bartbes>
hmm
<tuxbrain>
just to create a little bit of envy I have to listen music of one of my fabourit group before they release the album at work :P
<bartbes>
have you passed some options to help it play
<bartbes>
let me look them up
<rafa>
tuxbrain: let me try with the sync option. Anyway, to have that thing fluent I had to use the -v 0 -a 0 the worst quality for both, video and sound
<bartbes>
oh those are for AVD's :P
<bartbes>
but I guess you need to tell it to skip frames
<tuxbrain>
mmmm and how they look?
<rafa>
bartbes: I tried with mplayer autosync, framedrop, correct-pts, cache, etc..
<bartbes>
:(
<rafa>
tuxbrain: we need more people testing different options and doing a proper test for encoding and player
<bartbes>
ah well, as I said, who needs sync?
<rafa>
with documentation about things working and bad options
<rafa>
tuxbrain: I also tested the example_player that libtheora brings with its source code. It seems a good player to play, just that it is just an example, you do not have control of it. You can use it with cat file.ogv | example_player .. and CTRL+C to stop
<tuxbrain>
and it plays fine?
<rafa>
no fine, but looks promising
<rafa>
Because it asked for SDL library I could hack a bit that.. but no a lot of free time these days.
<rafa>
(no time= because I am planning to travel to buy some CDRs in Barcelona :D)
<tuxbrain>
hey any one has any report about java in NanoNote? is even in available in any distro?
<mth>
there is a J2ME VM for the Dingoo, so it shouldn't be too hard to make it work on the NN as well
<mth>
or do you want J2SE?
<tuxbrain>
well is to answer a possible costumer about the status due he had asked.
<mth>
I guess Debian would contain several VMs, although it's worth checking if they are also built for mipsel
<tuxbrain>
Personally out of some shell utilities, and some simply games I don't think java fits really in our device... but well I will try to know what costumer intentions are
<mth>
if the Java program is reasonably efficient, the NN sound be plenty fast for Java
<mth>
we used to run it on set top boxes with similar or lower specs
<rafa>
tuxbrain: for jlime OpenEmbedded wiki documentation says that we need JamVM and Cacao as the virtual machine and GNU Classpath as the class library, to have a full J2SE environment. Because I do not much about java I just will try to build and upload those OE packages to repo :)
<tuxbrain>
great thanks rafa :)
<tuxbrain>
and mth of course :)
<wpwrak>
tuxbrain: have you seen, my heavy metal project is advancing, too :)
<wpwrak>
rafa: will you want some lead for your ben, too ?
<wpwrak>
rafa: i still need to make one small change, though. the battery cover hits the counterweight in the middle, which is something it shouldn't do
<tuxbrain>
wpwrak: awesome job dude :) ... but... can you explain the objective of this? surelly you have explained before but I have missed it
<wpwrak>
rafa: also the crater landscape may be avoidable :)
<wpwrak>
tuxbrain: well, take a ben, open it ... and watch it fall over :)
<wpwrak>
tuxbrain: with this counterweight, it doesn't do that
<wpwrak>
tuxbrain: or at least not so easily
<tuxbrain>
ok :) understood I don't see this effect so often due It is allways attached to something :P
<wpwrak>
tuxbrain: so you don't take it to bars and restaurants to show it off ?
<rafa>
tuxbrain: for jlime OpenEmbedded wiki documentation says that we need JamVM and Cacao as the virtual machine and GNU Classpath as the class library, to have a full J2SE environment. Because I do not much about java I just will try to build and upload those OE packages to repo :)
<rafa>
tuxbrain: sorry I just did up arrow enter :)
<rafa>
wpwrak: let me check ..
<rafa>
wpwrak: sorry I still do not understand what happens when you open it.. and what it would avoid?
<rafa>
wpwrak: but looks nice :)
<rafa>
wpwrak: ahh.. now I understood as well :D
<rafa>
cool.. yes I always think that the screen is so heavy
<rafa>
wpwrak: is it easy to put? :)
<tuxbrain>
wpwrak: yes I do of course, and yes only a slightly  touch on the screen if opened more than 90 degrees will make it turn, but due is thinked to be used with thumbs at two hands I have not pay too much attention to this :)
<tuxbrain>
but you are right and you even have found a solution :) perfect!

wpwrak: Nice work!... tuxbrain suggested William Wallace words.. and I saw that movie as well.. there he used lead from some lead soldier toys of his son to make lead wullets.. so as a plus, I could use this nn lead in case I need to make some bullets as well :P
<rafa>
wpwrak: how did you do that exact part?
<tuxbrain>
rafa: are you not mixing Mel Gibson's movies? The patriot <->Braveheart , in middle ages.... bullets? :P
<tuxbrain>
well it can be cannon bullets but they will the whole toy soldiers battalion :)
<wpwrak>
rafa: it will be very easy to install. i still need to add a few things, though. the plan is to put it as follows: open the ben, remove the main pcb, put a drop of glue or silicone, insert the counterweight, another drop of glue, put a plastic sheet above it, then put two strips of isolation tape on the ben's pcb, and assemble. done.
<tuxbrain>
they will need
<rafa>
tuxbrain: yes :D .. but now I do not remember if mel gibson did it as william wallace though
<wpwrak>
rafa: (bullets) yeah, it's about 16-17 g, that should be good for a few. "dual use ben". or "weaponized ben" ;-)
<tuxbrain>
we have to include some non-warfare clause in our licences :P
<wpwrak>
rafa: i first took the geometry from one of the scans (ben-bottom-inside-500um)
<wpwrak>
rafa: then i broke the thing down into blocks with a rectangular footprint and a variable height. the height would always be the same along the x axis, but may change along the y axis.
<wpwrak>
rafa: then i wrote a script that defines these blocks and generates gnuplot output. with that, i could already get a first look.
<wpwrak>
rafa: then i changed it to also generate a solid in heekscad. with that, i could merge it with the scan, and see both together.
<wpwrak>
rafa: then i used heekscad and my mill to make a model of wax, to verify the geometry in the real device
<wpwrak>
rafa: finally, i again used heekscad to make a mold, and then i cast the solder (33% tin, 67% lead) with that mold
<rafa>
wow... really great work with your toys :)
<wpwrak>
rafa: yeah, i used quite a lot of them ;-)
<wpwrak>
now i still need to paint the thingies, as a protection when handling them, and also as an isolation, in case something touches them
<wpwrak>
i did a first tried with an acrylic coating (for electronics), and that worked so-so. that stuff it's also quite expensive. i tried a silicone coating, but that was a total failure. easy to apply, but doesn't isolate at all.
<wpwrak>
now i bought some paint and i'll see how that goes.
<rafa>
tuxbrain: ah.. you are right.. he did two movies.. and the patriot was the one with those lead he used :)
<tuxbrain>
Yes I can't remember what I have eat yesterday, or if I have shut the light off , but my brain is full of useless information as this one
