nicksydney | wpwrak: maybe try both balun and see which one is better ? | 00:55 |

nicksydney | wpwrak: http://downloads.qi-hardware.com/people/werner/anelok/tmp/ybox-draft-20140118.* --> why there is an asteriks ? | 00:56 |
nicksydney | wpwrak: what if you don't use R2 (0) what will happen ? | 00:57 |
wpwrak | (asterisk) a wildcard, to be expanded by humans :) | 01:03 |
nicksydney | pg 3 - pin 11,12,14,18,20,29 are not connected going to be left like that ? or maybe add a hackable pad/TP ? :) | 01:04 |
wpwrak | (R2) you mean omit the component ? the signal should be very weak then. you'd still send/receive *something* but with heavy loss | 01:04 |
wpwrak | hmm, seems that i screwed up DP/DM, too :-( well, at least that'll be easy to fix ... | 01:05 |
nicksydney | wpwrak: (R2) this is where I still don't understand .... R2 is a resistor and it supposed to be used for dropping current but in this case it is used to "strengthen" the signal ? thought normally use a capacitor ? | 01:06 |
wpwrak | (baluns) maybe later. swapping baluns means making and populating different boards. so it's not cheap. i'll get the parts, though | 01:07 |
wpwrak | (r2) no, it's just there to connect. it's a zero-ohm resistor. | 01:08 |
wpwrak | it could become an inductor, though. so it would (slightly) dampen high-frequency components of the signal. | 01:09 |
nicksydney | wpwrak: what if we increase the track instead of putting 0 R ? will that helped more ? | 11:13 |
wpwrak | that's not the idea :) the idea is to have a place to put a component if we want to tune the antenna | 12:49 |
wpwrak | right now, i'm not interested in tuning, so i just place a 0R (R2) in series and nothing (the NC cap, C3) in parallel | 12:50 |
wpwrak | NC = not connected / not placed / ... | 12:50 |
wpwrak | ybox-draft-20140118.* updated | 13:39 |
DocScrutinizer05 | other usual tags used instead of NC: DNP (do not populate), DNC, DNI (do not install) | 15:39 |
DocScrutinizer05 | particularly since "NC" is often used on switches for "Normally Closed" - as opposed to "Normally Open" (some say N means "Neutral" here, the semantics is the same though) | 15:40 |
DocScrutinizer05 | (also C may mean "Contact") | 15:41 |
DocScrutinizer05 | so NeitralContact is another valid expansion of NC | 15:41 |
DocScrutinizer05 | neutral even | 15:41 |

qi-bot | [commit] Werner Almesberger: modules/usb_a_rcpt_mid.fpd: enlarge 48458 bay by tolerance (master) http://qi-hw.com/p/kicad-libs/d83737d | 19:14 |
wpwrak | argh. with the heat, the junk in my cranial cavity simply doesn't work :-( | 19:16 |
wpwrak | milled a board and wondered why i had such a hard time to get it to start in the lower left corner. turns out if had the array index set to 1 and not 0. stupid ... | 19:17 |
DocScrutinizer05 | send half of that heat over here, we can use it | 19:32 |
wpwrak | about 38 C here ... how much do you have ? | 20:23 |
wpwrak | oh, and while i was taking siestas, your little project leaped over 60k. yet another nice round number. congrats ! | 20:24 |
DocScrutinizer05 | yeah, and just another 1500 donation for prototype made it leap over 61k, and made me aware that the meanwhile 8 prototypes (+ 1 series device per proto) had not been counted to the number of devices. So we leaped the 300 devices too :-D | 22:01 |

DocScrutinizer05 | -x | 22:03 |
larsc | hm, if prototypes make so much more money you should make a business out of selling prototypes, once the prototypes are done move on to the next project ;) | 22:15 |
DocScrutinizer05 | I don't think prototypes make much money, neither are they a huge selling qty, nor is the win margin better than for normal series devices. Rather the opposite, since 1500 gets you one prototype PLUs one series device for ~700 or even more. It might turn out the prototypes are the business with smallest win margin | 22:24 |
