wow, EMS has really impressed me
<whitequark>
five business days fron NY to Moscow
<wpwrak>
how is the CNC mill doing ? still blocked ?
<whitequark>
it's the CNC mill. I'm getting it today
<wpwrak>
wheee ! party time !
<whitequark>
yeah, just need to get a machine with LPT off craigslist
<wpwrak>
or make a USB dongle :)
<wpwrak>
there could be quite a market for a USB-to-parallel gerber dongle
<whitequark>
there already exists one, we've found it
<whitequark>
but it is actually cheaper for me to buy a used PC complete with IO devices, not to mention faster
<wpwrak>
make a competitor then :)
<whitequark>
but what I would make a prototype with? :D
<whitequark>
also, this actually may be a great idea to test it on something. a moderately complex board
<whitequark>
needs to be two-sided due to the LPT socket

hm, UV LED strip also arrived... but not power supply :(
<whitequark>
or photoresist for that matter
<wpwrak>
if you don't mind having a few level shifters, pretty much any usb-capable mcu would do
<wpwrak>
depends a bit on how much processing you want to have. i guess it could be relatively simple, just a handful of commands. lines, arcs, a few administrative commands, that's about it. you can always blink a LED if you receive something the firmware doesn't understand :)
<whitequark>
just make it understand gcode
<wpwrak>
well, gcode has tons of obscure things. you probably don't care to support all of them.
<whitequark>
hrm... on the other hand I wanted to redo its controller, since it's really dumb. you can't control spindle via lpt, for example
<whitequark>
well, may as well do both. or the best option will become clear after I play with it
<wpwrak>
while you're at it, add a little display so you can display diagnostics and the obiquitous X=xxx Y=yyy Z=zzz situation :)
<whitequark>
(gcode) just need to support what openscad and say inkscape emit
<whitequark>
and kicad/eagle
<whitequark>
they use like three commands
<wpwrak>
considering how many mills needs their dedicated pc, this could be a rather sought-after product. i see $$$ kickstarter potential :)
<wpwrak>
yes, they use three ... out of something like 300 ;-)
<whitequark>
well
<whitequark>
you sure make sense here. and we couldn't really find where to buy an adapter when we needed it.
<whitequark>
actually that sounds like an excellent idea.
<wpwrak>
:)
<wpwrak>
phase 1: seed planted. phase 2: wait until i find a way to get a mill through customs. phase 3: have some good use for the critter you'll make as well ;-)
<whitequark>
oh, you want this mill as well?
<wpwrak>
would be nice to have a more solid mill than the one i have
<whitequark>
neat!
<whitequark>
we could share modifications, too
<whitequark>
I want to try out so many things
<wpwrak>
i can imagine ;-)
<whitequark>
hadn't have a physical project to tickle my brain in a while :)
<whitequark>
*haven't

not a good night for me in terms of breadboarding.....tried out a 555 timer for my PCB on a breadboard thinking of creating a LED flasher but it didn't work..the LED just turn ON all the time no flashing...no matter what component i remove it keeps on lighting ON :(

whitequark: my trusted debugging tool now is my multimeter :)
<whitequark>
mm yeah, can be a pain
<nicksydney>
feels like throwing it to a brick wall !
<nicksydney>
2.5 hours spent for a frinkin' 555 timer debugging
<wpwrak>
sometimes that helps ;-)
<nicksydney>
at least in software i use git and revert back and put debugging :)
<nicksydney>
i think this is the reason why most software people don't go to hardware..it's hard to debug !
<larsc>
also the reason why most hardware people don't go to software, it's hard to debug ;)
<nicksydney>
larsc: i guess it comes to mindset..in takes time to switch from one to the other
<nicksydney>
being a software person i can have a fast turnaround but hardware is different
<nicksydney>
perhaps software people brain want to move quick and get quick result :)

wpwrak: my component stock is low at the moment so not going to throw anything at the brick wall :)

whitequark: could you please tell which toolchain were you using to build software for ingenic mips?
<whitequark>
CYB3R_: I think I built my own
<whitequark>
--target=mipsel-linux-gnu
<CYB3R_>
whitequark: did you apply ingenic patches?
<whitequark>
nope
<CYB3R_>
Okay, thank you.
<whitequark>
CYB3R_: why are you asking me?
<CYB3R_>
I remember you hacking xz0032 board
<whitequark>
thought so, heh
<whitequark>
do you have one?
<whitequark>
I actually have three lying around, collecting dust. now that I'm no longer a broke student I don't have very much use for them
<CYB3R_>
Mine was collecting dust for a long time and now I just remembered about it

<larsc>
Bierparkinglot?
<DocScrutinizer05>
whitequark: hardly any exist, I think
<DocScrutinizer05>
what sort of "bike"?
<DocScrutinizer05>
motorbike is supposed to park like a car - officially
<DocScrutinizer05>
nevertheless usually motorbikes are parked on the pavement
<roh>
DocScrutinizer05: depends on which city. in berlin you are allowed to park on the sidewalk even. as long as you dont block it
<DocScrutinizer05>
yeah, sidewalk is the better word than pavement, I guess
