Is this a reasonable plan? 2011-01-31 05:03 you have more ssl experience - any caveats? 2011-01-31 05:03 do I need to be worried about server load? 2011-01-31 05:16 wolfspraul: atleast login should be behind ssl. 2011-01-31 05:17 sure but I'm thinking about moving all behind ssl 2011-01-31 05:19 you know the firefox plugin which sniffs wifi and passwords? 2011-01-31 05:19 and enables you to login as people using no ssl around you ;) 2011-01-31 05:20 http://en.wikipedia.org/wiki/Firesheep 2011-01-31 05:20 no, but sorry I lost you.

I wish IRC nicknames carried an easy to finf associated GMT delta 2011-01-31 11:27 kristianpaul are you in same city as wpwrak a.k.a. Werner 2011-01-31 11:29 08:23 soft MMU is the perfect way to ensure MM pSOC runs as slow as posible, if not slower. 2011-01-31 11:37 08:23 //you make a good point. maybe soft MMU is not a brain dead idea after all. Maybe I am breain dead. It happens. 2011-01-31 11:38 rjeffries: no 2011-01-31 11:39 maybe I should go to sleep, wake up in 10 years to enjoy the MM SOC as asic I am just too damned impatient 2011-01-31 12:00 bassel what is your GMT delta? I am making a table I'll share later 2011-01-31 12:00 rjeffries GMT + @ 2011-01-31 12:00 GMT + 2 2011-01-31 12:07 rjeffries: (irc and gmt) maybe they just realized that a lot of people aren't synchronized with the position of the sun :) 2011-01-31 12:08 B_Lizzard: you asked for the patch for 2.6.37 2011-01-31 12:08 rjeffries: gmt -5, buga, colombia :-) 2011-01-31 12:09 works for me. time differnces make irc logs invaluable. 2011-01-31 12:09 http://en.qi-hardware.com/irclogs/latest.log.html 2011-01-31 12:09 larsc, 2.6.36 but it's fine, I fixed it 2011-01-31 12:09 it works 2011-01-31 12:10 ok 2011-01-31 12:11 offtopic question wrt IRC (trying to catch up, didn't use IRC before): comments sent by rjeffries to me "08:23 ...)" look like being send via /msg; however they appear in the irc log.Â Â answered via "/msg rjeffries ..." but result didn't show in irclog.Â Â something wrong on my side? 2011-01-31 12:12 in an earlier life I visited BogotÃ¡ on business to deliver technical prentation for a Swedish company 2011-01-31 12:13 dvdkhlng: they weren't private messages 2011-01-31 12:13 cold city :-) 2011-01-31 12:13 here is warm and windy 2011-01-31 12:13 but I worked form California for E 2011-01-31 12:14 rjeffries: btw, thanks for the input on the "MADE IN". let's hope this helps to avoid unnecessary troubles. 2011-01-31 12:14 that time stamp happened because I double clicked your comment in the #qi-hardware irc channel. I use smuxi as my irc client. not great, but it works 2011-01-31 12:16 wpwrak sometimes facts are facts. It's funny, I have no dog in thsi fight, but would rather not see wolf create hassle for his distributors or sharism at work 2011-01-31 12:16 dvdkhlng: it looks as if ron just copied and pasted your (/msg) replies. by the way, welcome to #qi-hardware ! i think now everyone who matters in ben-openwrt-land is here :) 2011-01-31 12:16 s/tsi/this 2011-01-31 12:16 larsc, rjeffries: thanks for the info.Â Â takes time to getting used to irc :)Â Â looks like irc-client on this side (rcirc.el) changes color of comment depending on whether my nick is mentioned. 2011-01-31 12:17 rjeffries: yeah. trying such things with customs is like wrestling with pigs. the pigs enjoy it and all you get is dirty. 2011-01-31 12:17 oh cool. So that is why I see some lines in RED here also. I thought wprak and others were treating me as a VIP 2011-01-31 12:17 dvdkhlng: many irc clients do this. helps you notice quickly when people talk about you behind your back ;-) 2011-01-31 12:18 cool beans 2011-01-31 12:18 wpwrak: hi, werner; yeah, studdying the rcirc.el source concurrently :) 2011-01-31 12:18 are you at the university or in industry 2011-01-31 12:21 rjeffries: btw, when addressing someone, it is more common to use theÂ Â nick:Â Â form (or some similar, e.g., command or semicolon would look right, too) 2011-01-31 12:21 I see so not use the 2011-01-31 12:22 rjeffries: the Â Â form is usually associated with a message coming from that person. so it using it also when addressing someone can create confusion about whether you're quoting that person 2011-01-31 12:22 thanks for the useful advice it has been MANY years since I used irc. But it's great in this application.perfect in fact 2011-01-31 12:23 rjeffries: not university, industry neither :p, i'm just freelance for industry 2011-01-31 12:23 needs to disable colors in irc. looking at his screen it's too obvious that this is not source-code and he's not working :) 2011-01-31 12:24 (irc) oh, i love it :) been quite a chat addict a long time ago and then decided just to stay away from that vile stuff, but i rediscovered it with openmoko, and it does really make cooperation more fluid. 2011-01-31 12:25 in many ways Twitter sorta kinda reinvented IRC, but for humans. but no "rrom" or channels so not good for this use case 2011-01-31 12:26 kristianpaul so you are what we call a hired gun. the only question would be, van you shoot straight? //smile 2011-01-31 12:27 so how are these COOL #qi-hardware logs created? I assume there is a bot that grabs stuff, then an offline program does some reformatting. I REALLY like the format 2011-01-31 12:30 rjeffries: qi-bot is wolfgang's never sleeping eye that watches over us :) 2011-01-31 12:31 dvdkhlng: or add colors to your sourcecode ;) 2011-01-31 12:31 did he also write the program that formats the logs I would assume? 2011-01-31 12:35 rjeffries: Generated by irclog2html.py 2.9.2 by Marius Gedminas - find it at mg.pov.lt! 2011-01-31 12:35 rjeffries: i think that's part of this eggdrop thing 2011-01-31 12:35 steve|m: ah, other package then :) 2011-01-31 12:47 larsc: :) 2011-01-31 12:54 roh: an AVR question. atmel traditionally gave the various timer pins names like "OC1A". e.g., here http://www.atmel.com/dyn/resources/prod_documents/2545S.pdf 2011-01-31 12:55 roh: however, with the ATmega*U2, this has changed to "OC.1A" etc.: http://www.atmel.com/dyn/resources/prod_documents/7799S.pdf 2011-01-31 12:55 uh. didnt know that 2011-01-31 12:55 roh: do you know the story behind that dot ? i find it rather troublesome to have two slightly different names for pins of virtually identical function blocks 2011-01-31 12:56 hmm 2011-01-31 12:56 well.. there are slim differences in different ones all the time for such stuff 2011-01-31 12:56 also because some have parts of the interfaces twice instead one 2011-01-31 12:57 roh: yeah, but a dot ? that seems like the mother of all gratuitous changes 2011-01-31 12:58 wpwrak: interresting anyhow 2011-01-31 12:58 in the end its just a define anyhow ;) 2011-01-31 12:59 roh: well, i'm at the circuit symbol now. don't like to diverge from the vendor naming (except for inversion) but don't like to diverge from what the (sw) source may use either. 2011-01-31 13:00 what are you using? N_foo? 2011-01-31 13:00 roh: for inversion ? nFOO 2011-01-31 13:00 ah. 2011-01-31 13:01 i wonder if atmel doesnt have a usb-cpu-wireless in once chip already 2011-01-31 13:01 steve|m: Thanks for this info re logs irclog2html.py 2.9.2 by Marius Gedminas 2011-01-31 13:02 roh: (usb-cpu-wireless) apparently not. at least not for ieee 802.15.4. haven't looked if they have any other rf. 2011-01-31 13:03 maybe if wolfspraul will share source for his bot, I can (with help from someone else) set up my own irc channel for other purposes entirely 2011-01-31 13:03 ATmega128RFA1 2011-01-31 13:03 http://www.atmel.com/dyn/products/devices.asp?category_id=163&family_id=676&subfamily_id=2124&source=left_nav 2011-01-31 13:03 roh: sans usb, no ? 2011-01-31 13:04 correct 2011-01-31 13:04 roh: also quite a monster. if you don't need such a big core, you're cheaper off with two chips 2011-01-31 13:04 roh: do you know approx price for that chip 2011-01-31 13:05 rjeffries: in digi-key we trust (also for pricing ;-) 2011-01-31 13:05 I have not mastered digikey i find it confusing. so it it $~10 usd or Less? 2011-01-31 13:05 nope 2011-01-31 13:05 more? 2011-01-31 13:06 $450USD 2011-01-31 13:06 SMILES 2011-01-31 13:06 sorry for caps 2011-01-31 13:07 rjeffries: price always depends on quantity. also, you have to consider if this is a chip major distributors stock. if they don't, it's a risk. (e.g., you may find your project delayed by several months while waiting for new parts from the manufacturer) 2011-01-31 13:07 someone famous in semiconducter industry once said "all chips will be $5usd exc ept for those that cost less: 2011-01-31 13:07 rjeffries: you really should learn to navigate digi-key. they're great. 2011-01-31 13:07 rjeffries: yeah, buy a few millions and you can negotiate almost any price :) 2011-01-31 13:07 wpwrak I will I promise 2011-01-31 13:09 I have a buddy who uses a killer NXP Arm SOC taht costs maybe $5 in modest quantities 2011-01-31 13:09 tuxbrain_away: you may get your little uart board in the end. i realized that it's a convenient interim step on the way to making the avr-based atusb work. 2011-01-31 13:09 once you design a complex chip, making a ton of them is pretty cheap 2011-01-31 13:10 wprak: a little uarts board would be goodness on so many levels. That is the fast track into Arduio land and Jee Labs 2011-01-31 13:10 woah ! 2011-01-31 13:11 Wolfgang you did this http://en.qi-hardware.com/wiki/File%3ARfm12_microsd.jpg ? 2011-01-31 13:20 ah, fun chip. 0.45 mm pitch. my smallest so far :) 2011-01-31 13:41 wpwrak where did you but the micrsod extension cable? http://en.qi-hardware.com/wiki/File:Rfm12_microsd.jpg 2011-01-31 13:42 s/Arduio/Arduino 2011-01-31 13:43 wpwrak: yahooooooo!!!! 2011-01-31 13:43 O_o 2011-01-31 13:44 I think i heard that from here too :-) 2011-01-31 13:44 rjeffries: i didn't make that one 2011-01-31 13:45 tuxbrain_away: btw you should sell Jeenodes as well 2011-01-31 13:45 nods to kristianpaul and tuxbrain_away that would be Most Excellent 2011-01-31 13:45 3.3V arduino-like board is intersting, even mor if it can talk with your nanonote as well ;-) 2011-01-31 13:46 kristianpaul that is what gets me excited by Jee Labs, plus he is an above average human being 2011-01-31 13:47 kristianpaul: is in the Todo list, I have contated them, margins are not very atractives but well , at the end I also sell NN isn't it? :P 2011-01-31 13:47 tuxbrain_away: margins :')) 2011-01-31 13:49 If someone achive to comunicate with them previously and post a step by step tutorial task can rise some priory 2011-01-31 13:49 priority 2011-01-31 13:50 wprank are you serious on that arduNN board? 2011-01-31 13:51 now ... what connector on the serial side ? three option: 1) narrow pcb pads for soldering a 50 mil cable directly to the PCB. 2) larger pcb pads to solder a 100 mil header directly to the PCB. 3) a proper 100 mil header on the PCB. 2011-01-31 13:51 tuxbrain_away: there be no arduNN. but a uart, yes :) 2011-01-31 13:52 ardu? i heard atmega 2011-01-31 13:52 heheheeh ok ok :) enough +1 to a proper conector no soldering 2011-01-31 13:52 tuxbrain_away: i need something to try the whole avr-with-ben bringup chain, and that one is less overhead than the new atusb. 2011-01-31 13:52 actually is on stusd sch right now tuxbrain_away 2011-01-31 13:52 s/stusd/atben 2011-01-31 13:54 hmmm. i better terminate that thing ... 2011-01-31 13:55 I also advocate for expose as many gpios on the chip , as many asÂ Â the board admit 2011-01-31 13:58 i was actually aiming for "small" :) 2011-01-31 13:58 well, let's see how the layout goes ... 2011-01-31 14:00 just let the pads, may be if some one want hack later can solder something on it.. 2011-01-31 14:00 hey,i dint knew it about atmegau8/32/16u2 familly 2011-01-31 14:02 nice have a 8bit MCU plus USB support, (so i finally can drop the non gcc suported picF18 MCU...) 2011-01-31 14:04 sorry I have just passed a sleepless night , was ending some task before going to sleep instead of having the space bar tatooed on the face , that newsÂ Â have inject some adrenaline on the system but just enough to work with a smile on the face and not work with eyes closed. c you 2011-01-31 14:04 chao 2011-01-31 14:05 hmm, i think i soon can have enought stuff to order from digikey :-) 2011-01-31 14:50 This is interesting.

I clicked on that link but maybe I do not understand navigation, or no PDF yet. whatever 2011-01-31 17:50 rjeffries: just open the schematic with KiCad 2011-01-31 17:51 I will need to downlaod kiCad. I did a while back then deleted it when I was not using it 2011-01-31 17:52 so are you adding a hardware UART on Blikinlights, or is this just bit banging with 3.3 volt levels? sorry to be so ignorant 2011-01-31 17:53 by "just" I am NOT deprecating your effort, simply wondering 2011-01-31 17:54 bit banging could support a fairly decent serial rate. maybe 56kbps or so?? 2011-01-31 17:56 wpwrak: by the way, is you PCB etching workflow documented somewhere? :) 2011-01-31 17:57 which chip is used yo do the 6 to 10 i/o muxing? 2011-01-31 17:58 steveM all I lnow is that over of Playboy or Maxim or similar girlie magazine us ESSENTIAL 2011-01-31 17:58 better tha the expensive photo paper 2011-01-31 17:58 tell you wife of gf you buy it for the articles and the cover ONLY 2011-01-31 18:00 steve|m: hmm, i described it here a few times but it's not "properly" documented. there's a also a fairly involved CNC workflow connected to this. 2011-01-31 18:00 rjeffries: there's an AVR that handles the UART. talks SPI to the ben. 2011-01-31 18:01 wpwrak: ah, okay 2011-01-31 18:01 this would be fun as well: http://www.youtube.com/watch?v=R0F0yLOnQZM ;) 2011-01-31 18:02 seems i lost the track about why blinkenlights have a UART port now... 2011-01-31 18:02 rjeffries: doing it all with bit-banging would be cute, but that's not quite what i'm looking for this time. what i'm after is a simple AVR that gets flashed from the ben. once i have that working, i can apply it to the new atusb. 2011-01-31 18:02 ah flash ! 2011-01-31 18:02 http://www.mikrocontroller.net/attachment/99611/IMG_0340.JPG 2011-01-31 18:02 wprak that is the correct (smile) answer. yes yes and HELL yes 2011-01-31 18:02 kristianpaul: well, i made a subproject in blinkenlights. seemed a bit empty :) 2011-01-31 18:03 wpwrak: uart? 2011-01-31 18:03 is not empty :-) 2011-01-31 18:03 well missing code.. 2011-01-31 18:03 steve|m: nice :) 2011-01-31 18:03 brb i must leave 2011-01-31 18:03 kristianpaul: yes, now uart/ is there :) 2011-01-31 18:03 my brain is empty. van we all agree on that? 2011-01-31 18:03 steve|m: i use CNC only to make the board. the rest is chemnical. 2011-01-31 18:04 wpwrak: (programming the avr) ah, so you're using bitbanging ISP to program the avr.. nice idea 2011-01-31 18:04 Better living through chemistry.TM Dupont 2011-01-31 18:04 then you don't need ISP testpoints 2011-01-31 18:04 steve|m: that's the idea, yes. and the SPI interface can then also serve as the host communication interface :) 2011-01-31 18:05 yep, really nice that the MOSI/MISO/SCLK stuff is also uses for ISP on the avr 2011-01-31 18:06 Hello there :) 2011-01-31 18:07 wpwrak: by the way, here's the original thread.. http://www.mikrocontroller.net/topic/206547 2011-01-31 18:07 attach a 30$ laser from dealextreme to your CNC machine and you're set :) 2011-01-31 18:07 If I want to install the SDL lib on my NanoNote for C + SDL coding, does it works exactly like manually installing it on my x86 linux machines ? 2011-01-31 18:10 steve|m: (laser plotter) hmm, seems rather complex. i thought this was milled. 2011-01-31 18:28 hmm, does serial programming of avrs still work if nRESET is configured as I/O ? the data sheet isn't quite clear on that. 2011-01-31 18:28 (reset disabled) i.e., RSTDISBL programmed to zero. 2011-01-31 18:29 hmm, google says "no" 2011-01-31 18:31 wpwrak: no, doesn't work unfortunately (own bad experience) 2011-01-31 18:32 AVR fusbite mistake #1 2011-01-31 18:32 if you don't have a high voltage programmer, you're screwed 2011-01-31 18:35 steve|m: an ugly design "feature" 2011-01-31 18:38 wpwrak: indeed.. generally, the AVR has too much fusebits.. I really started to like other architectures which have no fusebits at all 2011-01-31 18:39 steve|mÂ Â Google Chrome translate extension is my friend. 2011-01-31 18:39 like the msp430, which will run off the internal RC oscillator, and you switch to the external clock source in software, with fallback if there's no clock and so on 2011-01-31 18:40 guess there are many others out there which do it this way 2011-01-31 18:41 has started doing some TI launchpad hacking, and reprogrammed the big MSP used for programming the target yesterday 2011-01-31 18:42 steve|m: yes, that clock selection is rather antiquated 2011-01-31 18:43 steve|m did you garb some of those 430 Launchpad at the $4.30 price, incl. shipping in US? 2011-01-31 18:43 hmm, not enough i/os for an interrupt line. sigh. wish atmel wouldn't insist on requiring nSS for slave mode ... 2011-01-31 18:43 s/garb/grab 2011-01-31 18:44 wpwrak: interrupt Ben -> AVR? you could use a pin change interrupt on any other pin 2011-01-31 18:44 steve|m: interrupt avt->ben. i.e., when data has been received. the problem is that i'm running out of signals. 2011-01-31 18:44 rjeffries: I have the launchpads from a german electronics seller for 4,50 each 2011-01-31 18:46 steve|m I assume 4,50 Euros still cheap 2011-01-31 18:46 steve|m: an 8:10 card has 6 data lines. full spi already occupies 4 of them. i need one more for the clock and one for reset. leaving 0 for interrupts. well, unless playing games with configuring spi on and off. not sure if this works. 2011-01-31 18:49 is looking at the schematics 2011-01-31 18:50 is already making radical changes :) 2011-01-31 18:51 if you have place for testpoints, SDA cand SCL ;) I2C is always good to have ;) 2011-01-31 18:53 steve|m: naw, no room. i want this to be small :) 2011-01-31 18:53 or just connect them to rxd and txd, then you can configure them as high-Z and use either/or :) 2011-01-31 18:53 but well.. might be over-engineered 2011-01-31 18:55 i would need a lot of vias for that. 2011-01-31 18:55 anyway, bitbanged i2c would always be possible if someone should need that 2011-01-31 18:58 for what is the CLK line used? for providing the a clock to the atmega? is the internal 8MHz rc-oscillator insufficient? 2011-01-31 19:04 steve|m: the RC clock is only accurate +/- 10% (without additional calibration). alas, i don't see where in the data sheet they specify the clock accuracy the uart needs. 2011-01-31 19:04 but +/- 10% seems too much. 2011-01-31 19:05 even +/- 5% would be a lot 2011-01-31 19:06 wpwrak: and which clock can you provide via the CLK output of the ben? 2011-01-31 19:06 well, if we don't use it, we can recycle XTAL1 for other uses:) 2011-01-31 19:06 the SDIO clock. the ben's crystal clock is quite accurate. a bit too noisy for RF, but should be perfect for this use. 2011-01-31 19:08 okay 2011-01-31 19:11 wpwrak: if you should use the internal OSC, and can enable/disable the SDIO clock independently, this would also make an interrupt pin :) 2011-01-31 19:13 even quite resource saving, since you could use it as timer0 clock input and then generate a timer interrupt 2011-01-31 19:32 steve|m: i can use the SDIO clock on the ben side also as regular GPIO, yes 2011-01-31 19:32 ah, even better 2011-01-31 19:33 (or interrupt, etc.) 2011-01-31 19:39 [commit] Werner Almesberger: uart: the AVR requires nSS for slave mode http://qi-hw.com/p/ben-blinkenlights/d3ab4ab 2011-01-31 21:43 roh: do you know what did happen with openmoko ML?

2011-01-31 22:21 or just because Android is the current fashion and they were so excited about it that they picked it for the name of the project? 2011-01-31 22:22 wolfspraul: i dont think, well, carlos just started the thread 2011-01-31 22:22 it's not supposed to run Android?
