2012-01-29 05:56 oh wow, sorry about how stupid that sounded. 2012-01-29 05:56 okay. 2012-01-29 05:57 On my nanonote, my girlfriend helped me take it apart, because for the past two years, there's been a piece of graphite lunking around in there. 2012-01-29 05:57 it hadn't bugged me much 2012-01-29 05:57 but suddenly, the graphite moved up and shorted out the board. 2012-01-29 05:58 so, she helped me open up the case, and the thing fell out, eventually (it was stuck UP there), and we got it out 2012-01-29 05:59 when it was put back together, the little rubber piece of plastic that covers the LED 2012-01-29 05:59 was gone, and we can't find i. 2012-01-29 05:59 *it. 2012-01-29 05:59 I know it functions fine without it, but at the same time I worry about dust, fuzz, etc getting in there. 2012-01-29 06:00 so is there a way for me to buy a new rubber piece for the light? 2012-01-29 06:00 also, is there a way for me to buy qi-hardware stickers? 2012-01-29 06:00 because you guys have the neatest logos. 2012-01-29 06:01 like, I'm specifically looking for the Ben symbol in a circle, like what it has when it boots. 2012-01-29 06:01 because that looks killer. 2012-01-29 06:02 hm, you'll have to wait for wolfgang for an official replacement and stickers 2012-01-29 06:02 alrighty 2012-01-29 06:02 a quick fix for the led rubber would be with transparent silicone 2012-01-29 06:03 just put a drop there, then shape it with your finger and swipe off the excess material 2012-01-29 06:03 ....where would I get that? 2012-01-29 06:03 silicone can be shaped easily if you wet the finger (or other tool) with isopropyl alcohol 2012-01-29 06:04 hmm. any place that has plumbing supplies should have silicone 2012-01-29 06:04 ah alright 2012-01-29 06:04 hardware store, etc. 2012-01-29 06:05 well, still, I always like to support you guys, and buying one from you guys would be preferable 2012-01-29 06:05 or the big supermarkets where you can get all sort of DIY thing 2012-01-29 06:05 also, if I get one of those, there's a damn good chance I'm gonna gum up my nn 2012-01-29 06:05 silicone is easily removed :) 2012-01-29 06:06 it's a pretty neat material for little DIY jobs 2012-01-29 06:06 well, and you can seal your bathroom with it, etc. ;-) 2012-01-29 06:06 also, is there a place in the US that sells the atben stuff? because I feel like the shipping from tuxbrain is going to be huge 2012-01-29 06:06 well, like I used to use Sugru with stuff, is it like that? 2012-01-29 06:06 i don't know. the only ones i've heard of are tuxbrain and pulster 2012-01-29 06:07 yes, like sugru but more liquid 2012-01-29 06:07 actually, until today, Sugru was what made up the little feet on my nanonote 2012-01-29 06:07 hehe ;-) 2012-01-29 06:07 but it was in the way of a screw, so they had to go 2012-01-29 06:08 yeah, a tinkerer's device should not hide the screwd under rubber feet. instead, it should show them with pride ! :) 2012-01-29 06:09 indeed 2012-01-29 06:09 i think sugru is actually based on silicone. they just made it a bit tougher. 2012-01-29 06:09 yeah, I think so too 2012-01-29 06:10 next time I get some more sugru though I'm making some new feet 2012-01-29 06:11 you can probably also use silicone for that. cheaper :) 2012-01-29 06:12 silicone comes in colors. transparent, white, and black should be easy to get. but maybe you have a much larger choice. 2012-01-29 06:14 true, but silicone doesn't dry into as frictional a surface, like my nanonote wouldn't slide down a slanted surface, at all 2012-01-29 06:15 I had a plastic repair kit somewhere 2012-01-29 06:15 that I think was silicone based 2012-01-29 06:15 and it was really smooth 2012-01-29 06:17 silicone has a rubberish texture 2012-01-29 06:18 so i think it should be fine for feet. but you can just try whether it works. it's not expensive. 2012-01-29 06:19 there's also a stronger variant, polyurethane. that's a bit trickier to handle, though. and you won't get it off things as easily :) 2012-01-29 06:20 ahh 2012-01-29 06:20 yeah 2012-01-29 06:20 also though, still wanna buy stickers 2012-01-29 06:20 and maybe an atben thing, but that's for tuxbrain 2012-01-29 06:21 (stickers) yeah, they probably don't have these at the DIY store :) 2012-01-29 06:21 ah, maybe wolfgang can also sell atben/atusb. i think he once thought about it. but i'm not sure if anything came out of it. 2012-01-29 06:22 that's no big deal, I gotta figure out how to afford one, but other than that I'm fine 2012-01-29 06:30 but either way, should I just shoot a message to the mailing list? 2012-01-29 06:35 yeah, why not. or hang our here until wolfgang shows up. 2012-01-29 06:35 alrighty, sounds good! 2012-01-29 06:36 i think he's still in germany. it's 07:35 there. may take a few more hours :) 2012-01-29 06:37 ahh alright 2012-01-29 06:37 man, that guy's a globetrotter. 2012-01-29 06:37 where does he actually live 2012-01-29 06:37 ?

Then both get crowbarred via their own diode and common thyristor), but also ensure a more sane power-up sequence (Zener working as diode when biased reverse makes sure 2012-01-29 13:10 5V rail never is significantly lower than 3V3, forward Zener ensures 3V3 comes up in sync with 5V) 2012-01-29 13:11 B_Lizzard [B_Lizzard!~havoc@athedsl-120749.home.otenet.gr] has joined #qi-hardware 2012-01-29 13:13 CcSsNET: welcome to Qi Hardware first of all, I don't recall you here earlier 2012-01-29 13:13 ah, mail from your grandmother's project arrived :) 2012-01-29 13:13 thanks for stopping by, and feel free! :-) some people here have several year history, but don't let that make you feel it's not your place somehow. the only thing we really care is to be as friendly as possible. 2012-01-29 13:14 DocScrutinizer: hmm, couldn't this cause trouble when powering up ? 2012-01-29 13:14 which sometimes collides with our passion, admittedly :-) 2012-01-29 13:14 open mobile, made available ;-P 2012-01-29 13:15 i'm also not quite sure how you're start the thyristor. a schematic drawing would help :) 2012-01-29 13:15 wpwrak: which kind of trouble? only problem I see is power on Zener 2012-01-29 13:15 it's on the contrary avoiding some otherwise possible problems 2012-01-29 13:15 trouble = on power up, the 5 V rail is up before 3.3 V. so if this trips the crowbar ... 2012-01-29 13:16 this doesn't trip the crowbar, and 5V up befor 3V3 is cured by Zener anyway 2012-01-29 13:17 Zener might fuse when 3V3 never comes up though 2012-01-29 13:18 e.g due to a short on 3V3 rail 2012-01-29 13:19 as Zeners always "fuse to short" , this would cause both 3V3 and 5V either engage short protection, or (after short removal) cause crowbar 3V§ OVP trip by the short to 5Vintroduced by short Zener 2012-01-29 13:20 depending on 5V regulator I'd expect both rails go into overcurrent protection with a short on 3V3 though 2012-01-29 13:20 and Zener survives 2012-01-29 13:22 only "risk": make sure 3V3 has some minimal load *always* as otherwise the Zener leakage might cause OV on 3V3 and trip crowbar 2012-01-29 13:22 i think we have that 2012-01-29 13:22 I'm sure about that :-) 2012-01-29 13:23 I think it's a pretty simple yet nifty and failproof design for a OVP 2012-01-29 13:24 hm. i'd be worried about obscure failure modes 2012-01-29 13:24 plus en passant makes sure no too nasty things happen on power-up sequencing 2012-01-29 13:25 nah, I already evaluated all whatever obscure failure patterns 2012-01-29 13:25 it's safe in my book 2012-01-29 13:25 rock solid design 2012-01-29 13:25 no matter which component fails in which way 2012-01-29 13:25 jluis [jluis!~jluis@2001:5c0:1400:a::313] has joined #qi-hardware 2012-01-29 13:25 of course there'S no substitute for tests on real iron 2012-01-29 13:26 the other thing i don't like about it is that we can probably get all the OVP we want by just picking the right regulator chips. so once we finally get to clean up the power circuit, which is a mess, then we should be able to have a nice integrated solution (where someone else has already figured out and fixed the weird corner cases :) 2012-01-29 13:26 no regulators protect against reverse fed OV 2012-01-29 13:27 (power up) externally regulated 5V is the main supply for everything. 3.3V is derived from 5V 2012-01-29 13:27 except shunt reulators 2012-01-29 13:28 plus a crowbar is meant to catch component brakage in rgulator block as well as externally caused OV 2012-01-29 13:28 so you'll hardly find a regulator chip with built-in crowbar 2012-01-29 13:29 (shunt) deutsch: quer-regler (as opposed to the usual laengs-regler) 2012-01-29 13:30 quer-regler not commonly used anymore, since they have abysmal efficiency 2012-01-29 13:31 only place to use them is to regulate 20+kW PSU when load changes a few 2 or 3% only 2012-01-29 13:32 then your parallel/shunt regulator only consumes some 600W rather than several 1000 2012-01-29 13:33 mmh. nice and warm in winter :) 2012-01-29 13:33 duh, actually each Zener stabilization is a shunt regulator circuit 2012-01-29 13:35 the one BIG advantage of shunt reg: extremly low source impedances are possible for the PSU 2012-01-29 13:35 as current from buffer/source has no huge transistor or FET to go thru 2012-01-29 13:36 owadays with rather low R(DS) FETs this argument is somewhat moot, it was valid intimes of germanium transistors 2012-01-29 13:37 now we're *really* OT :-P 2012-01-29 13:38 :) 2012-01-29 13:39 just checked the 3.3 V regulator we use. doesn't do anything fancy, which was to be expected 2012-01-29 13:39 of course not 2012-01-29 13:40 for OVP you won't find anything reasonable on regulator domain, as you also got buffer C (a lot of them) 2012-01-29 13:40 btw, an integrated solution can also simply consist of OVP detection with a global shutdown. (e.g., with a multi-voltage regulator) 2012-01-29 13:40 OVP needs to discharge all those buffer C in NO time -> crowbar 2012-01-29 13:41 yeah, sounds reasonable 2012-01-29 13:41 which effectively answered your last post before it got posted 2012-01-29 13:42 but ... post-M1r4, i think. adam had enough fun with the even simpler input protection circuit of M1rc3. i don't think he'll appreciate getting a crowbar added to all the other changes in M1r4, of which there are many 2012-01-29 13:43 of course you can try to find a better BOM /circuit for the crowbar, but you won't get much better on it than the prev quoted BOM 2012-01-29 13:43 jluis [jluis!~jluis@2001:5c0:1400:a::313] has joined #qi-hardware 2012-01-29 13:44 if this was twitter "crowbar" would probably be the trending word for the day 2012-01-29 13:44 if he's not willing to add a circuit that simply can get NC by not populating the components, he does something wrong 2012-01-29 13:45 not A SINGLE bridge/0R needed, just don't populate the components - can you come up with a design that has less risk to implement on next production rev? 2012-01-29 13:46 if adam refuses to consider it, you should find somebody else for that task 2012-01-29 13:49 wolfspraul [wolfspraul!~wolfsprau@p5B0AFE68.dip.t-dialin.net] has joined #qi-hardware 2012-01-29 13:51 wpwrak, hi, I just got back.

It's just I have (like with all of my code) already a catch-all/exit-strategy for *every* possible oopsie when I come up with a suggestion 2012-01-29 13:53 nickoe: the rounded pads consist of half-circle plus a rectangle (may be zero) plus another half-circle 2012-01-29 13:54 wpwrak, but in the file it just says rpad for round pads 2012-01-29 13:54 nickoe: the half-circles are internal drawing elements (and the whole pad becomes an "oval" pad in kicad anyway) 2012-01-29 13:55 nickoe: yes. round = circle or rectangle terminating in half-circles 2012-01-29 13:56 maybe I should ask you if fped can construct a pad...

;-) http://2.bp.blogspot.com/_NVQujPOPx2c/TDiRmBNrQFI/AAAAAAAARQs/hqb1PwdJYmk/s400/2.jpg 2012-01-29 23:20 yeah :-P 2012-01-29 23:21 kristianpaul: ah, that's just the EVB. so you simply connect to the header 2012-01-29 23:21 I'd not expect to get a GPS fix with antenna <1m away from M1 with extension cable, resp away from cable (any part of it) 2012-01-29 23:21 header is not same pitch 2012-01-29 23:21 DocScrutinizer: oh sure 2012-01-29 23:21 DocScrutinizer: is 3 meters out to the window 2012-01-29 23:21 good 2012-01-29 23:22 out the window, then a cable over to the friends at arecibo ... 2012-01-29 23:22 hehe 2012-01-29 23:23 so what's the problem with that cable, kristianpaul ? 2012-01-29 23:23 nothing 2012-01-29 23:23 you already are in trouble with it? 2012-01-29 23:23 aah, ok 2012-01-29 23:24 nope that i know, just wpwrak made me think about it yet 2012-01-29 23:24 I'd first see if any troubles arise 2012-01-29 23:24 10MHz still is kinda LF 2012-01-29 23:24 16Mhz actually .) 2012-01-29 23:24 hmm 2012-01-29 23:25 what signals do you transmit there? 2012-01-29 23:25 timing critical? 2012-01-29 23:25 IF sampling real data two bits 2012-01-29 23:25 2bit PCM? 2012-01-29 23:25 with clock? 2012-01-29 23:25 16.384 Mhz 2012-01-29 23:26 with, not which 2012-01-29 23:26 I.E. sync or async 2012-01-29 23:26 sync 2012-01-29 23:27 kyak [kyak!~kyak@95-24-99-235.broadband.corbina.ru] has joined #qi-hardware 2012-01-29 23:27 kyak [kyak!~kyak@unaffiliated/kyak] has joined #qi-hardware 2012-01-29 23:27 make sure you get proper termination at both ends 2012-01-29 23:27 proper :/ 2012-01-29 23:28 consider clock line timing adjustments by introducing delay lines to get some 90° phase shift 2012-01-29 23:28 so your data lines are sampled in center of eye-pattern 2012-01-29 23:28 DocScrutinizer: http://en.qi-hardware.com/w/images/2/2a/Sigelogic.png 1. clock 2. sign 3. magnitude thats what came trought ribbon cable 2012-01-29 23:29 aah your clock is twice the data rate? good 2012-01-29 23:30 though, WTF are those discontinuities on CLK? 2012-01-29 23:30 cheap logic analizer 2012-01-29 23:30 in scope looks better 2012-01-29 23:32 so I gather you sample on rising edge of clock? 2012-01-29 23:32 i got same discontinuities with 4Mhz clock.. 2012-01-29 23:32 rising 2012-01-29 23:34 the discontinuities look like aliasing between time frame pace of logic analyser and real signal/clock 2012-01-29 23:34 I gather your analyzer just does 2 or 3 fold oversampling 2012-01-29 23:35 or not even that 2012-01-29 23:36 clock is twice the data rate, no, data rate is same as clock 2012-01-29 23:36 actually sligtly <2 2012-01-29 23:36 looks like 30Mhz or something 2012-01-29 23:36 but i still not worry as i decimate later 2012-01-29 23:37 also all the SoC that sample this signals (milkymist) run syncronous from the same gps receiver clock 2012-01-29 23:37 just make sure you sample in centwer of eye pattern on RX side 2012-01-29 23:38 ok 2012-01-29 23:38 also tha pic above is not my current sampling setup (sorry i was trying to give an idea) 2012-01-29 23:39 don't forget you got quite some propagation delay on a 50cm flat ribbon cable, and that this delay might differ between clock and data lines, if only a bit 2012-01-29 23:40 ribbon is ~13cm 2012-01-29 23:40 whatever 2012-01-29 23:40 ok 2012-01-29 23:40 i'll move to PCB-glue solution later anyway 2012-01-29 23:40 you might want to sync a PLL on RX side and basically run async 2012-01-29 23:41 recovering clock from edges on datalines as well as clock 2012-01-29 23:41 in the other side (FPGA) there is a buffer 2012-01-29 23:42 s/as clock/as clock line/ 2012-01-29 23:42 DocScrutinizer meant: "recovering clock from edges on datalines as well as clock line" 2012-01-29 23:43 but maybe that's all a big overkill, and you're just fine with what you got there 2012-01-29 23:43 fine for now :) 2012-01-29 23:43 good 2012-01-29 23:43 as wpwrak said i still not have a fix 2012-01-29 23:44 also i dont need it yet, as soon as i got tracking a satellite :) 2012-01-29 23:45 DocScrutinizer: but i already have your advices, wich is relly great 2012-01-29 23:45 yw 2012-01-29 23:45 considering the atenna will come later to the same box, i need think about that too 2012-01-29 23:45 I'm always glad to share some of my... ideas 2012-01-29 23:46 I'm open to listen it :) 2012-01-29 23:47 meh, I should go to sleep 2012-01-29 23:47 good sleep then :) 2012-01-29 23:48 18:48 still here and still lot to do.. 2012-01-29 23:48 sleep $(( 60 * 60 * 4 )) 2012-01-29 23:49 o/ 2012-01-29 23:49 and drive to work?
