designing ? 2014-05-01 15:33 i find that kicad sometimes hangs (or at least it used to some time ago) when i have multiple instances running. so it's a good idea to save often. also had some issues when working with zones, but i haven't experienced these lately 2014-05-01 15:34 ah, and fped also has a yet unsolved problem that seems to be related to deletions. so safe often there, too :) (fped versions the files for you, so you don't have to worry about saving things you may later regret) 2014-05-01 15:37 pcercuei: developing a taste for german beer ? :) 2014-05-01 15:38 slowly but surely

developers use a better number representation in the first place 2014-05-01 17:24 performance doesn't matter much here; using (slow) rational arithmetic would be fine 2014-05-01 17:28 yeah, usually you use fixed point 2014-05-01 17:28 with enough precision to represent metric/imperial well 2014-05-01 17:29 oh, I see. in C++, you write std::ratio_multiply, not a*b 2014-05-01 17:31 hm? 2014-05-01 17:31 I was wondering if C++ had support for rational numbers, and it seems to be done in a horrible way 2014-05-01 17:31 I'm not sure what is the point of using rationals anyway 2014-05-01 17:32 with proper language support, they are the easiest choice 2014-05-01 17:32 not necessarily most correct, and anyway implementing fixed-point is not hard 2014-05-01 17:32 not necessarily most correct? 2014-05-01 17:32 s,most correct,best,. 2014-05-01 17:33 well, they are slower than fixed point for sure, but other than that? 2014-05-01 17:33 it's not even fixed-point actually, you just represent everything in µm and convert it to the user's choice of unit 2014-05-01 17:33 sb0: unless you back rationals with bigints, they're not infinitely precise 2014-05-01 17:33 yeah sure 2014-05-01 17:37

2014-05-01 20:28 sb0: that's why it's important to review schematics :) missed dots tend to be a very minor problem. can't even remember having any issues with them 2014-05-01 20:29 oh, but you should follow the rule of never making connected crosses 2014-05-01 20:29 only T-connections, never +. a + always means "not connected". 2014-05-01 20:30 (that's a rule for the designer to follow, not something kicad would need. though it may be nice if it could enforce it) 2014-05-01 20:32 in the old milkymist days, we compiled a set of style guidelines:

which footprint you recommend to use if not using SOT diode package ? 2014-05-01 22:59 that would depend on the diode you choose to use ;-) 2014-05-01 23:00 schottky diode like this one http://www.fairchildsemi.com/ds/MB/MBR0530.pdf 2014-05-01 23:02 well, find the manufacturer's recommended footprint drawing and see if anything in

2014-05-01 23:06 cool...copy image file and paste into IRC paste the file itself in this format :) hhehehe 2014-05-01 23:06 ok will dig up the .pdf and print the footprint to see which one matches 2014-05-01 23:07 anyway, i don't think there's a "generic diode". alas, the diode makers stubbornly insist in not using "standard" packages like 0402, 0603, etc. 2014-05-01 23:07 but there are a bunch of SOD packages that seem to be reasonably common. so defining them could be useful. 2014-05-01 23:10 ok thanks 2014-05-01 23:11 as i said, i try to stay clear of reversible diodes. hmm, there was a japanese engineering design principle with a specific name for this 2014-05-01 23:12 the basic idea being that if you try to put a part in any way but the correct way, it will simply not fit 2014-05-01 23:13 ok 2014-05-01 23:13 diodes in symmetric packages are the perfect anti-pattern for this :)
