15:26.35 | ahycka | hahahaha |
15:28.54 | ahycka | the problem is that i did 1 year work in 4months |
15:29.27 | ahycka | and im finding mistakes before power on the pcb :S |
15:30.06 | wpwrak | yeah, skipping reviews can be a great time saver ;-) |
15:30.11 | ahycka | before having PCB in my hands!!! |
15:30.16 | ahycka | of course! |
15:30.39 | ahycka | so, there are mistakes that i can solve with cables |
15:30.53 | wpwrak | lesson to learn for your boss: be less hasty, you'll get there faster :) |
15:31.01 | ahycka | call him |
15:31.13 | ahycka | because i told today and he said: what?!?!!??! |
15:31.25 | wpwrak | well, yellow wire is cheap :) |
15:31.55 | ahycka | but another mistake is a big 1, the pcb will wor in the laboratory at 25degrees |
15:32.00 | ahycka | but not at 70 :S |
15:32.13 | ceene | and it must work at 70 :) |
15:32.25 | ceene | so it'll catch fire, as samsung :) |
15:32.41 | ceene | you're now on the edge of current technology |
15:33.25 | 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 :) |
15:34.49 | ceene | it'll be installed on southern spain |
15:34.56 | ceene | so it won't be very cold |
15:35.13 | ahycka | hahahahahahaha |
15:35.19 | ceene | not that it matters much, once all the amplifiers are powered up... |
15:35.32 | ceene | "the system's temperature will be kept down via means of a cold plate" says the specifications |
15:35.40 | ceene | later on it reads "cold plate will be at 70ºC" |
15:35.46 | ceene | somebody doesn't understand the meaning of "cold" |
15:35.51 | ahycka | ambient temperature!! |
15:35.57 | 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 :( |
15:35.58 | ahycka | 70degrees minimum |
15:36.03 | ceene | :D |
15:36.10 | ceene | the empire where the sun never sets |
15:36.17 | ceene | we've come a long way from that |
15:36.42 | ceene | now we're the small kingdom in which unemployment never falls down... |
15:36.50 | wpwrak | "cold" = you receive only minor burns when touching it |
15:37.45 | ceene | i think popcorns could be made there |
15:42.20 | DocScrutinizer05 | astronomers call everything except hydrogen and helium a 'metal' |
15:43.51 | DocScrutinizer05 | just idly wonders how temperature susceptibility is a layout issue |
15:44.01 | DocScrutinizer05 | forgot the thermal vias? |
15:44.07 | ceene | nop |
15:44.12 | ceene | but |
15:44.17 | ceene | if you have something which disspates 3W |
15:44.23 | ceene | with 24º of ambient temperature |
15:44.24 | ceene | it may be okay |
15:44.31 | ceene | because it'll reach maybe 60º |
15:44.49 | ceene | if it's already at 70, an increase of 36º is 106ºC |
15:44.50 | ceene | fire |
15:44.57 | ceene | so in this case, it's a power supply |
15:45.05 | ceene | that could've been designed taking this into consideration |
15:45.18 | ceene | coulda shoulda woulda |
15:45.33 | DocScrutinizer05 | but that's not layout :-o |
15:45.39 | ceene | nope, that's before layout |
15:45.47 | ceene | but ahycka does everything |
15:45.52 | DocScrutinizer05 | :-D |
15:46.08 | DocScrutinizer05 | I *love* layouters with a brain |
15:46.12 | ceene | lol |
15:46.49 | 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 |
15:46.50 | DocScrutinizer05 | in OM we had a few that were like "...but the wire in shematics also does that! " |
15:47.04 | ceene | ouch |
15:48.23 | ceene | we're a pack |
15:48.24 | 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 |
15:48.27 | ahycka | FIRE!!!! |
15:48.29 | ceene | she does all the hardware and i do all the software |
15:48.45 | ceene | she asks me sometimes something about her hardware and i ask her sometimes something about my software |
15:48.50 | ceene | we could conquer the world, i believe |
15:48.53 | ahycka | hahahaha |
15:49.02 | ceene | if we only had the time and the will, and the evilness that is required... |
15:50.50 | DocScrutinizer05 | yes, you seem to be the dream team |
15:51.46 | ceene | you should tell that to our boss... |
15:55.53 | *** join/#neo900 Pali (~pali@Maemo/community/contributor/Pali) |
15:56.30 | DocScrutinizer05 | 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 |
15:58.53 | DocScrutinizer05 | the BOM is pretty much (over-)complete, and placement between UPPER and LOWER is also finalized as much as possible |
15:59.13 | ceene | great |
15:59.34 | DocScrutinizer05 | IOW component placement can already get done |
16:00.10 | ahycka | perfect! at least my boss buy me and i7 16GB RAM laptop |
16:00.17 | DocScrutinizer05 | for routing I don't expect a lot of changes either |
16:00.21 | ahycka | so, ill get it home, and ill use it :) |
16:02.53 | 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 |
16:09.59 | ahycka | DocScrutinizer05, ill study the schematics, but not now, ill do in October, promise |
