offers suggestions for name of Step2 device: Rosetta, Dual, Dexter. Rosetta is about the most peaceful one, given how Dual is similar to Duel.

wpwrak: Sure, I read a lot. :-) Read some stories based on Darkly Dreaming Dexter or something. Not watching movies, though.

schematics editing is in full swing. but it'll still take a while. we also keep finding and fixing little bugs (and glad that we find them now, when you don't need a soldering iron / board respin to fix them :)

ahycka: xould you already start checking and familiarizing with kicad?
<DocScrutinizer05>
you want 4.0.3 version (at very least 4.0.2)
<ahycka>
i'll download 4.04

by the moment my mind is in my job's design and altium, i have a some mistakes that i wouold like to fix in the prototype...

ahycka: naw, just ship it. when the boards explode at customers, you get a lot a of free PR. just look at the stellar job samsung's marketing did ;-)
<ahycka>
hahahaha
<ahycka>
the problem is that i did 1 year work in 4months
<ahycka>
and im finding mistakes before power on the pcb :S
<wpwrak>
yeah, skipping reviews can be a great time saver ;-)
<ahycka>
before having PCB in my hands!!!
<ahycka>
of course!
<ahycka>
so, there are mistakes that i can solve with cables
<wpwrak>
lesson to learn for your boss: be less hasty, you'll get there faster :)
<ahycka>
call him
<ahycka>
because i told today and he said: what?!?!!??!
<wpwrak>
well, yellow wire is cheap :)
<ahycka>
but another mistake is a big 1, the pcb will wor in the laboratory at 25degrees
<ahycka>
but not at 70 :S
<ceene>
and it must work at 70 :)
<ceene>
so it'll catch fire, as samsung :)
<ceene>
you're now on the edge of current technology
<wpwrak>
put somewhere in the small print of the manual that it must only be used in ushuaia, during winter. else, the warranty is void. that should cover the issue :)
<ceene>
it'll be installed on southern spain
<ceene>
so it won't be very cold
<ahycka>
hahahahahahaha
<ceene>
not that it matters much, once all the amplifiers are powered up...
<ceene>
"the system's temperature will be kept down via means of a cold plate" says the specifications
<ceene>
later on it reads "cold plate will be at 70ºC"
<ceene>
somebody doesn't understand the meaning of "cold"
<ahycka>
ambient temperature!!
<wpwrak>
ceene: ah yes, been a while since tierra del fuego would have counted as "southern spain". seems that your product is a bit late :(
<ahycka>
70degrees minimum
<ceene>
:D
<ceene>
the empire where the sun never sets
<ceene>
we've come a long way from that
<ceene>
now we're the small kingdom in which unemployment never falls down...
<wpwrak>
"cold" = you receive only minor burns when touching it
<ceene>
i think popcorns could be made there
<DocScrutinizer05>
astronomers call everything except hydrogen and helium a 'metal'
* DocScrutinizer05
just idly wonders how temperature susceptibility is a layout issue
<DocScrutinizer05>
forgot the thermal vias?
<ceene>
nop
<ceene>
but
<ceene>
if you have something which disspates 3W
<ceene>
with 24º of ambient temperature
<ceene>
it may be okay
<ceene>
because it'll reach maybe 60º
<ceene>
if it's already at 70, an increase of 36º is 106ºC
<ceene>
fire
<ceene>
so in this case, it's a power supply
<ceene>
that could've been designed taking this into consideration
<ceene>
coulda shoulda woulda
<DocScrutinizer05>
but that's not layout :-o
<ceene>
nope, that's before layout
<ceene>
but ahycka does everything
<DocScrutinizer05>
:-D
<DocScrutinizer05>
I *love* layouters with a brain
<ceene>
lol
<ceene>
she only offered to do the routing of neo because it's easier than a full schematic, and taking over somebody else's schematic is basically a pain :D
<DocScrutinizer05>
in OM we had a few that were like "...but the wire in shematics also does that! "
<ceene>
ouch
<ceene>
we're a pack
<ahycka>
the problem is that i design a power supply to give 3.7V because after it, there are a lot of LDOs to 3.3V, so, disipation is very low, but i need to up from 3.7 to 4.5
<ahycka>
FIRE!!!!
<ceene>
she does all the hardware and i do all the software
<ceene>
she asks me sometimes something about her hardware and i ask her sometimes something about my software
<ceene>
we could conquer the world, i believe
<ahycka>
hahahaha
<ceene>
if we only had the time and the will, and the evilness that is required...
<DocScrutinizer05>
yes, you seem to be the dream team
<ceene>
you should tell that to our boss...

anyway please install kicad, check out latest Neo900 project files (ping wpwrak about details to gain access and have an account) and already please start to have a few looks and familiarize yourself with kicad eeschema and pcbnew
<DocScrutinizer05>
the BOM is pretty much (over-)complete, and placement between UPPER and LOWER is also finalized as much as possible
<ceene>
great
<DocScrutinizer05>
IOW component placement can already get done
<ahycka>
perfect! at least my boss buy me and i7 16GB RAM laptop
<DocScrutinizer05>
for routing I don't expect a lot of changes either
<ahycka>
so, ill get it home, and ill use it :)
<DocScrutinizer05>
there are just mainly offsheet symbols that point to nowhere, that needs fixing by adding two GPIO extenders for that stuff and route some of them dangling signals to BB-xM interface to genuine GPIO
<ahycka>
DocScrutinizer05, ill study the schematics, but not now, ill do in October, promise
