| wpwrak | zrafa: thanks ! seems that debian ran into the same problem: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=515431 | 01:04 |
|---|---|---|
| wpwrak | zrafa: and there's even a worse incarnation, for beta releases: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=563344 | 01:04 |
| wpwrak | so .. the bad spectrum is not a new problem: http://downloads.qi-hardware.com/people/werner/wpan/tst-tx/ | 03:00 |
| wpwrak | (in a way, that's good - means that i can debug it with the latest boards, which support the constant frequency test mode) | 03:03 |
| kristianpaul | oh, adam is cooking something :-) | 06:14 |
| wolfspraul | cooking what? | 06:24 |
| wpwrak | hmm .. the clock looks rather awful. with lots of noise just in the FM range. | 08:37 |
| wolfspraul | that's the ben clock you are reusing? | 08:59 |
| kristianpaul | wolfspraul: i dont understand very well cause i traduced his blog entry (http://east3yrswest3yrs.blogspot.com/2011/01/blog-post_12.html) | 09:19 |
| kristianpaul | Looks healthy | 09:20 |
| wolfspraul | ah I see | 09:20 |
| kristianpaul | :-) | 09:22 |
| wpwrak | wolfspraul: yes. but it seems that i'm catching the FM outside the ben. | 09:24 |
| qi-bot | [commit] Wolfgang Spraul: added snippet about new metal sheet http://qi-hw.com/p/m1/26e2d32 | 09:24 |
| wpwrak | let | 09:26 |
| wpwrak | 's make the caps a little larger ... | 09:26 |
| wpwrak | that got rid of some of the reflections, but not the "hill" | 09:34 |
| wpwrak | hmm. now the question is how much of this horror is real and how much comes from the scope probe. http://downloads.qi-hardware.com/people/werner/wpan/rework-20110112/ | 10:09 |
| wpwrak | the DC offset is rather puzzling, too | 10:10 |
| qi-bot | [commit] Joachim Steiger: added missing background image http://qi-hw.com/p/m1/5228a87 | 12:01 |
| qi-bot | [commit] Joachim Steiger: Merge branch 'master' of git@projects.qi-hardware.com:m1 http://qi-hw.com/p/m1/a0552c4 | 12:01 |
| wolfspra1l | roh: there it is, nice :-) | 12:02 |
| wolfspra1l | thanks! | 12:02 |
| qi-bot | [commit] Joachim Steiger: added more parts and material properties http://qi-hw.com/p/m1/9228004 | 12:16 |
| qi-bot | [commit] Wolfgang Spraul: added some sourcing notes for case parts http://qi-hw.com/p/m1/d61c132 | 14:51 |
| qi-bot | [commit] Werner Almesberger: atrf-txrx: new option -C to control CLKM output http://qi-hw.com/p/ben-wpan/cb7afe1 | 18:15 |
| qi-bot | [commit] Werner Almesberger: atrf-txrx.c (enter_test_mode_231): disable CLKM in AT86RF231 test mode http://qi-hw.com/p/ben-wpan/e90c596 | 18:15 |
| kristianpaul | :/, i dont know why my computer just shutdown... it was installing some rtems depences last time i had contact it by ssh | 19:26 |
| kristianpaul | anyway.. lets see how it goes after this | 19:28 |
| wpwrak | roh: hmm, in the usb button box, where the angled sides meet the top. were the angled terminations of the side part also laser-cut ? | 19:31 |
| wolfspraul | kristianpaul: do you know much about the milkymist one expansion header? | 19:51 |
| wolfspraul | I am looking at it right now, wondering how flexible it is... | 19:52 |
| kristianpaul | let me see | 19:53 |
| wpwrak | wolfspraul: "versatile" or "how far can it bend before it breaks" ? ;-) | 19:53 |
| kristianpaul | J21 is that expacion header? | 19:55 |
| kristianpaul | sheet 3 | 19:55 |
| kristianpaul | a PCB layout i missing btw, i thin is not much hard export from altium.. | 19:56 |
| kristianpaul | in pdf i meant* | 19:56 |
| kristianpaul | wolfspraul: whos needs IO we have _wonderfull_ usb :-D | 19:58 |
| wolfspraul | I think there are two. J3 and J21. | 19:58 |
| kristianpaul | where is J3? | 19:58 |
| wolfspraul | J21 has 16 pins, J3 has 18 pins. | 19:59 |
| wolfspraul | J3 is right next to it. | 19:59 |
| wolfspraul | I think they are both expansion headers, no? | 19:59 |
| wolfspraul | strange, the bom lists both j3 and j21 as 2*9 http://en.qi-hardware.com/wiki/Milkymist_One_RC2_BOM | 20:02 |
| wolfspraul | but J21 has 2*8, and J3 has 2*9 | 20:02 |
| wolfspraul | I think... | 20:02 |
| kristianpaul | i need a rc3 pic, wait amin | 20:04 |
| kristianpaul | rc2* | 20:04 |
| kristianpaul | both are 2*9 | 20:06 |
| kristianpaul | may be some pins not routed | 20:07 |
| wolfspraul | oh you are right! | 20:07 |
| wolfspraul | it was changed on rc2 | 20:07 |
| wolfspraul | ok so on rc2, we have 2 2*9 expansion headers | 20:07 |
| kristianpaul | to be fair from where you get your rc3 pdf sch? | 20:08 |
| wolfspraul | there is no rc3 yet | 20:08 |
| wolfspraul | the files are a bit messy, sorry :-) | 20:09 |
| wolfspraul | I just google | 20:09 |
| wolfspraul | he he | 20:09 |
| kristianpaul | lol | 20:09 |
| kristianpaul | s/rc3/rc2 | 20:09 |
| wolfspraul | the only way to really this this up is all into kicad etc. but that's not my #1 priority right now | 20:09 |
| wolfspraul | to really clean this up | 20:09 |
| wolfspraul | rc2 schematics pdf: http://www.milkymist.org/mmone/rc2_schematics.pdf | 20:10 |
| wolfspraul | J21 is documented on page 3, still haven't found J3 | 20:10 |
| wolfspraul | (and the pdf is not searchable :-)) | 20:10 |
| kristianpaul | ha i catch you ! | 20:10 |
| kristianpaul | i tought u already founded | 20:10 |
| kristianpaul | i still looking for J3 too | 20:11 |
| kristianpaul | (and the pdf is not searchable) PAIN !! | 20:11 |
| kristianpaul | ok from m1 ucf i can see 12 IO | 20:13 |
| wolfspraul | ah j3 is for audio only | 20:13 |
| wolfspraul | page 1, I think j3 is hooked up to the audio codec | 20:14 |
| kristianpaul | for how long it will? :-) | 20:14 |
| wolfspraul | so only j21 is the fpga expansion header | 20:14 |
| kristianpaul | https://github.com/lekernel/milkymist/blob/master/boards/milkymist-one/synthesis/common.ucf (from line 298 ) | 20:15 |
| kristianpaul | audio, hum, what i fell is missing a extension cable here.. | 20:16 |
| kristianpaul | any way | 20:16 |
| kristianpaul | s/fell/feel | 20:16 |
| kristianpaul | for gps-sdr 13 pins are not so bad, not sure for a captiva cmos... | 20:25 |
| wolfspraul | kristianpaul: yeah for image sensor it's not enough | 20:28 |
| kristianpaul | The MIC2550A | 20:31 |
| kristianpaul | is 2.0 USB compliant | 20:31 |
| kristianpaul | but nah, is too much to deal with i think | 20:37 |
| wolfspraul | kristianpaul: correct | 20:39 |
| wolfspraul | Milkymist One will be fun | 20:39 |
| wolfspraul | there are like 1000 really nice, really important open TODOs | 20:39 |
| wolfspraul | the main thing in this project is to pick your battles wisely | 20:39 |
| wolfspraul | I am still mentally wandering around the project trying to understand all the various things that work or don't work, could work, should work, will never work, etc. | 20:40 |
| wolfspraul | and whether they are hard or easy to fix, depend on each other or not, and so on | 20:40 |
| roh | wpwrak: nope. the angled stuff was filed after lasering it in a way that the were 'just long enough' | 22:35 |
| roh | filed manually | 22:35 |
| roh | then glued | 22:35 |
| roh | also sandpaper was used | 22:35 |
