| 00:59.58 | RobotGuy | sighs |
| 01:00.13 | ds2 | I should sell some adapter cables for $25 each }:-) |
| 01:00.27 | prpplague | RobotGuy thats silly, just make a cable, its not like you would use it for something |
| 01:00.38 | RobotGuy | ds2: You don't know what I need to adapt to. |
| 01:00.54 | ds2 | for $50, I'll make it custom ;) |
| 01:01.19 | RobotGuy | Are the Olimex boards using a non-standard JTAG connector? |
| 01:02.46 | RobotGuy | Olimex uses a 2x10 and Flyswatter has a 2x7 |
| 01:02.54 | prpplague | ds2 hehe you'll end up spending more than 50 if you do it yourself |
| 01:03.10 | ds2 | prpplague: I have a pile of parts to reuse ;) |
| 01:03.13 | prpplague | RobotGuy there techincally no standard for jtag ports |
| 01:03.22 | ds2 | Jtag is 4 wires, IIRC |
| 01:03.24 | prpplague | RobotGuy there are 2 recommended configurations for ARM devices |
| 01:03.35 | prpplague | RobotGuy a 2x10 and a 2x7 configuration |
| 01:04.29 | RobotGuy | I know why the Flyswatter uses the 2x7 - there is just barely room for that on the Hammer. |
| 01:04.43 | prpplague | yea |
| 01:05.11 | prpplague | we had a choice of using a small connector, something like a 1x5 .1" or do something like small 2mm connectors |
| 01:05.21 | prpplague | we even discussed using a small flex connector |
| 01:05.43 | ds2 | Mictor connectors ;) |
| 01:05.45 | prpplague | but we felt that we needed to stick with the .1" them |
| 01:05.50 | RobotGuy | 0.1" spacing for the win! |
| 01:06.06 | baked_potatoe | prpplague: Thanks |
| 01:06.11 | ds2 | or 2.50mm pitch }:-) |
| 01:06.13 | prpplague | baked_potatoe ?? |
| 01:06.35 | baked_potatoe | The nTRST. I am checking on that now. |
| 01:06.43 | prpplague | ahh |
| 01:07.06 | ds2 | just randomly throw in a few 2.50mm pitch connector while keeping the rest at 100mil |
| 01:07.12 | ds2 | ought to be fun |
| 01:07.16 | prpplague | ds2 uh what? |
| 01:07.37 | RobotGuy | ~lart ds2 |
| 01:07.37 | purl | pulls out a ClueBat (tm) and thwaps ds2 |
| 01:07.48 | ds2 | what?! O:-) |
| 01:08.10 | prpplague | <ds2> just randomly throw in a few 2.50mm pitch connector while keeping the rest at 100mil |
| 01:08.16 | prpplague | what are you refering to? |
| 01:08.27 | ds2 | prpplague: any connector |
| 01:08.33 | ds2 | makes it fun, lots of fun |
| 01:08.43 | prpplague | ds2 why would we use 2.5mm ? |
| 01:09.09 | ds2 | prpplague: that's the fun part, use 100mil on all the short (4 pin rolls) but make the longer roles 2.5mm |
| 01:09.26 | ds2 | then just video tape the person working the board |
| 01:09.52 | prpplague | uh i no clue what you are refering to |
| 01:10.03 | ds2 | 100mil == 2.54mm |
| 01:10.13 | prpplague | ds2 yes |
| 01:10.14 | ds2 | so for longer connectors, the 0.04mm accumulates |
| 01:10.49 | ds2 | but most people don'tbother measuring to 0.04mm so you get to see someone struggle trying to fit a 100mil connector on a 2.5mm plug or vice versa :) |
| 01:10.59 | prpplague | uh and how does that save space on the jtag? |
| 01:11.09 | ds2 | doesn't...it is just "fun" |

| 01:12.29 | prpplague | MonMotha purl logs content here |
| 01:12.40 | MonMotha | though, I think the meanest things I've seen to date are "#define while if" and "#define struct union" |
| 01:12.44 | MonMotha | prpplague: true |
| 01:13.36 | ds2 | I think the 2.5mm/0.1" thing should have never existed; but since it does... it is a useful way of tracking poor copy cats |
| 01:15.00 | MonMotha | ds2: I've had so many problems with round-off on that |
| 01:15.30 | MonMotha | people will spec things to 0.1mm, when in reality they were designed in english units and are actually some multiple/fraction of 2.54mm |
| 01:15.39 | MonMotha | Amp and Molex are both culprits on that one |
| 01:15.58 | ds2 | I get very very suspicious when I see 2.5 or 1.2/1.3mm anywhere |
| 01:16.10 | ds2 | got to go |
| 01:16.48 | prpplague | we considered using a small flex similiar to the one for the barcode scanner on the m5900 - http://elinux.org/M5900 |
| 01:20.06 | ce_geek | prpplague: Ping |
| 01:20.46 | prpplague | ce_geek pong |
| 01:21.14 | MonMotha | prpplague: it isn't too bad when you get into smaller, non "post" based connectors. Most people just get a ballpark measurement of the pitch then visually match it up or use part number stamped on the part, but for connectors where a person is likely to try to match it to a "standard series" metal pin/post connector, the 2.5/2.54 difference is a pain |
| 01:21.26 | MonMotha | same with screw-down terminal blocks. 5.08 and 5.00mm are both very common |
| 01:22.08 | prpplague | MonMotha yea i'm familar with the problem, just didn't realize that ds2 was being malecious |
| 01:22.08 | ce_geek | prpplague: Yeah sorry I disappeared to go screw off this afternoon. Back at work trying to make up for it a little :-P |
| 01:22.19 | prpplague | ce_geek oh yea forgot |

| 01:22.36 | MonMotha | prpplague: ah |
| 01:22.39 | prpplague | ce_geek i can only imagin |
| 01:23.08 | MonMotha | prpplague: next time you're editing some dusty old header that gets included in everything, but nobody ever looks at, just add "#define while if" and "#define struct union" to them |
| 01:23.11 | ce_geek | prpplague: :( Yeah. Not sure how different they are since you last saw them. |
| 01:23.16 | MonMotha | the former saves execution time, and the latter saves space |
| 01:23.34 | MonMotha | and it'll make everybody absolutely HATE you after they spend HOURS debugging it :) |
| 01:23.41 | prpplague | ce_geek well i didn;t save a copy and i;d like to look over them |

| 01:26.14 | ce_geek | prpplague: Anything specific that you'd be interested in having documented more thoroughly, or at all for that matter? |
| 01:26.28 | ce_geek | prpplague: I'm going to play with the JFFS2 thing next I think. |
| 01:26.39 | ce_geek | prpplague: And right after that is some hardware programming with the one-wire temperature sensors I have. |
| 01:26.53 | ce_geek | prpplague: To make a simple temperature web server thing |
| 01:27.45 | prpplague | ce_geek well to be honest i've become so jaded to the dev environment, i'm not entirely sure what most people who have no linux dev experience are looking for |
| 01:27.58 | prpplague | ce_geek which is a bad thing, imho |
| 01:27.59 | g1powermac_PB | what do you guys use for cross compilation toolchains for your arm boards? |
| 01:28.19 | prpplague | g1powermac_PB i use buildroot to do all my basic builds |
| 01:28.49 | g1powermac_PB | prpplague: hmm, k, trying to figure out what would be the best way to cross compile qtopia |
| 01:29.31 | g1powermac_PB | was looking at scratchbox as its been configured to build stuff for the zipit already |
| 01:30.17 | MonMotha | prpplague: hey, can you recommend a hackable (i.e. I can make it do WPA Radius) 802.11a/b/g AP? with a halfway decent radio in it? |
| 01:30.22 | MonMotha | or anybody, for that matter |
| 01:30.53 | g1powermac_PB | likes his buffalo wrt routers he has |
| 01:31.30 | ce_geek | prpplague: I'm hoping I can put together some good stuff. I'll be talking to you and others here quite a bit in the days to come to get it done though :-/ |
| 01:31.32 | g1powermac_PB | don't recall the model number of them though |
| 01:31.54 | g1powermac_PB | but I did modify them and put a massive antenna on one :-) |
| 01:32.09 | RobotGuy | g1powermac_PB: Do they actually route or are they just gateways? |
| 01:32.10 | g1powermac_PB | and they're running openwrt |
| 01:32.19 | g1powermac_PB | they're routers |
| 01:32.26 | prpplague | MonMotha sorry no |
| 01:33.00 | prpplague | ce_geek yea the simple temperate web server thing seems to be getting alot of requests |
| 01:33.02 | RobotGuy | g1powermac_PB: As in with multiple static IPs? |
| 01:33.24 | ce_geek | prpplague: Oh really? |
| 01:33.35 | prpplague | yea i've have 5 or 6 requests for that |
| 01:33.41 | ce_geek | prpplague: That's exciting actually, that someone might actually care about something I might be able to provide documentation about! :) |
| 01:33.51 | MonMotha | g1powermac_PB: I can deal with either a straight bridge or a router, but it cannot force me to do NAT |
| 01:34.00 | ce_geek | prpplague: Perfect. Consider it done. |
| 01:34.00 | MonMotha | it doesn't have to be hackable if the stock firmware will do what I need |
| 01:34.20 | g1powermac_PB | MonMotha: it's totally customizable since they can run openwrt |
| 01:34.28 | prpplague | MonMotha sorry i've not done AP stuff in a while |
| 01:34.29 | MonMotha | yeah, I figured |
| 01:34.38 | MonMotha | prpplague: np. I just know they're a commonly hacked item |
| 01:34.38 | prpplague | i've become too specialized these days |
| 01:34.49 | RobotGuy | g1powermac_PB: Link to model? |
| 01:34.51 | g1powermac_PB | RobotGuy: yea, you could do multiple static ips on them |
| 01:34.56 | prpplague | my mindset is all about mobile devices these days |
| 01:35.10 | RobotGuy | Mobile Robots are Mobile Devices too. :D |
| 01:35.11 | MonMotha | I'd really love to do a mobile device |
| 01:35.16 | g1powermac_PB | RobotGuy: ask me tomorrow, I'll get the model number off of them |
| 01:35.17 | MonMotha | we're thinking about one at work |
| 01:35.31 | RobotGuy | g1powermac_PB: OK |
| 01:35.41 | prpplague | MonMotha i've been feeling like i've hit a plateau with my education |
| 01:35.42 | g1powermac_PB | they're at the store and I'm currently resting on my couch at home :-) |
| 01:36.21 | prpplague | MonMotha been trying to decide on some good conferences to attend to get down and dirty with more kernel driver dev |
| 01:36.52 | prpplague | MonMotha i'm considering getting aml to pay for a class in san fran on advance kernel driver dev |
| 01:37.27 | g1powermac_PB | really should go into biomedical engineering. . . |
| 01:37.38 | RobotGuy | I've been thinking of getting a LinkSys WRT54GL, but will get an Edimax BR-6504n (http://www.edimax.com/en/produce_detail.php?pd_id=222&pl1_id=1&pl2_id=2) first. |
| 01:37.44 | prpplague | g1powermac_PB growing mutants in the basement? |
| 01:38.22 | RobotGuy | prpplague: Linux Plumber's Conference. :D |
| 01:38.35 | g1powermac_PB | prpplague: nah, but my current passion due to some recent family and my own medical issues has inspired me to go into nutritional science |
| 01:38.57 | ce_geek | prpplague: I'm approaching the temp server from two different angles. I've got boa to play nice and give a nice, simple "Hello World" kind of a page. Next I need to get the hammer board to talk to the temperature sensor. Then I'll worry about making the two pieces come together. |
| 01:39.03 | prpplague | i know you can learn alot on your own, but i'm a firm believer that you need to associate with live people to advance |
| 01:39.23 | g1powermac_PB | prpplague: that is such a true statement |
| 01:39.59 | prpplague | one sec phone |
| 01:40.21 | MonMotha | prpplague: what I've found is the best thing to do is just sit down and start hacking, really. You've got enough embedded experience (I presume) to know the common pitfalls that can happen when you're running on raw hardware with minimal OS protection |
| 01:40.30 | MonMotha | and yes, I've panic'd several kernels :) |
| 01:41.07 | MonMotha | the biggest issue isn't usually the driver itself, but knowing a) Which kernel subsystem to hook into, and b) The API that subsystem uses (and which one to use, if there are several) |
| 01:41.10 | g1powermac_PB | has been in and out of dr offices and hospitals lately. . . |
| 01:41.28 | MonMotha | mailing lists are often a great help |
| 01:41.43 | g1powermac_PB | due to heart arrhythmia and other weird things |
| 01:42.04 | MonMotha | Most of the kernel subsystems have a developers list. They are usually pretty willing to help people interested in hacking on the code, especially providing pointers to existing documentation that may be difficult to find/index. |
| 01:42.17 | g1powermac_PB | plus my grandmother just recently went in for breast cancer surgery and my uncle had open heart surgery last year |
| 01:43.54 | prpplague | returns to read log |
| 01:44.31 | RobotGuy | Next month, I am going to be very heavily into interfacing various sensors to Hammer. |
| 01:44.43 | prpplague | ce_geek good plan |
| 01:44.54 | prpplague | ce_geek got a datasheet on the temp sensor? |
| 01:44.55 | g1powermac_PB | the whole medical stuff has really interested me |
| 01:45.05 | ce_geek | prpplague: Indeed. uno momento. |
| 01:45.36 | prpplague | MonMotha yes hacking is good, however there is a point when you do need more info |
| 01:45.45 | RobotGuy | Sienna sent me three things to interface and I have several of my own. |

| 01:46.03 | prpplague | looks |
| 01:46.27 | MonMotha | prpplague: like I said, mail list |
| 01:46.52 | MonMotha | ah, 1-Wire. Linux support 1-Wire. |
| 01:47.07 | RobotGuy | I have some of those. |
| 01:48.00 | RobotGuy | I already have my I2C compass and serial Bluetooth module on my carrier board. |
| 01:48.07 | prpplague | ce_geek hmm, no 3.3v version of that? |
| 01:48.52 | ce_geek | prpplague: If not, I'll just have to do some level shifting to get it to work :-/ |
| 01:49.04 | ce_geek | prpplague: That is unfortunate :-/ |
| 01:49.24 | MonMotha | prpplague: datasheet says you can run that sensor at 3.3V |
| 01:49.28 | MonMotha | down to 2.8 in fact |
| 01:49.44 | ce_geek | Yeah I thought I had looked at it and determined it wouldn't be a problem, hunting now to find where I saw that. |
| 01:50.07 | MonMotha | and you should be able to run the 1-Wire bus at 3.3V, as well |
| 01:50.50 | ce_geek | I see, page 24 |
| 01:50.51 | prpplague | ahh i hadn't read far enough |
| 01:51.02 | MonMotha | yeah, Maxim/Dallas's datasheets kinda suck |
| 01:52.31 | RobotGuy | I want one of these: http://www.sparkfun.com/commerce/product_info.php?products_id=8454 |
| 01:52.37 | prpplague | ce_geek http://www.lecad.uni-lj.si/~leon/other/wlan/wrt54ow/ |
| 01:53.16 | ce_geek | prpplague: hahaha sweet |
| 01:54.23 | prpplague | not sure why they used a serial port |
| 01:54.51 | ce_geek | prpplague: Hopefully this will be as easy as I think it will be and I can do tons of other cool stuff. |
| 01:55.01 | ce_geek | prpplague: Stepper motor control would be _awesome_ |
| 01:55.27 | ce_geek | prpplague: Need to get some optos for that though, seems like an appropriate place for some isolation. |

| 01:58.30 | prpplague | ce_geek what is you want to do that you can't with wrt? |
| 01:58.38 | ce_geek | prpplague: I don't know. |
| 01:58.48 | prpplague | ahh ok, hehe |
| 01:58.53 | ce_geek | prpplague: Any ideas? |
| 01:59.01 | prpplague | too tired for today |
| 01:59.15 | ce_geek | prpplague: If you think of something reasonable, let me know. |
| 01:59.33 | prpplague | will do, just been a long day |
| 01:59.46 | ce_geek | prpplague: No problem. |
| 01:59.53 | prpplague | got a new set of boards i've been working on bringing up |
| 01:59.59 | ce_geek | prpplague: Ah |
| 02:00.15 | prpplague | the one wire interface should be easy for that part |
| 02:00.29 | prpplague | makes a note to order some |
| 02:00.50 | MonMotha | I thought that some of the 1-Wire temp sensors were already supported by Linux |
| 02:01.02 | ce_geek | prpplague: Tempted to do it with a familiar chip first |
| 02:01.29 | ce_geek | http://www.digitemp.com/ |
| 02:03.01 | prpplague | intersting |
| 02:03.13 | prpplague | MonMotha thats what i was looking at |
| 02:04.34 | ce_geek | prpplague: Is it any less interesting if I just get that to work? |
| 02:04.45 | ce_geek | prpplague: That's exactly what one of the links you sent me uses. |
| 02:05.26 | prpplague | nope, very interesting imho |
| 02:05.43 | ce_geek | prpplague; Perfect. |
| 02:05.57 | ce_geek | dives in head first |
| 02:06.06 | prpplague | http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=drivers/w1/slaves/w1_therm.c;h=fb28acaeed6c4ab01235f09b764b8d0b7e1b20b6;hb=HEAD |
| 02:07.05 | prpplague | looks like its fully supported |
| 02:07.15 | prpplague | just gotta figure out the schematic connections |
| 02:08.26 | prpplague | http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob;f=drivers/w1/masters/w1-gpio.c;h=9e1138a75e8bb52618f9d561acc8c0b3c664683e;hb=HEAD |
| 02:08.35 | prpplague | there is the one wire gpio implementation |
| 02:08.51 | MonMotha | ah yes, the bit-banged 1-wire implementation |
| 02:09.02 | MonMotha | I'm guessing it's pretty CPU hungry, due to the self-clocked nature of the bus |
| 02:09.43 | prpplague | yea, i need to look at the datasheet for the s3c2410 |
| 02:09.46 | MonMotha | there are UART, I2C, and (I think) SPI 1-Wire masters that would alleviate a lot of that problem if you see anything |
| 02:09.53 | prpplague | seems like the i2c controller has a 1-wire options |
| 02:10.09 | MonMotha | really...that's kinda odd |
| 02:10.18 | MonMotha | I2C and 1-Wire have virtually nothing to do with each other |
| 02:10.39 | prpplague | yea, but iirc there is an option for it one one the SoC's i've been using |
| 02:10.46 | prpplague | just can't remember which one |
| 02:11.39 | g1powermac_PB | hmm, this would be a cool thing to build and then attach it to a hacked zipit: http://www.eng.utah.edu/~jnguyen/ecg/ecg_index.html :-) |
| 02:11.53 | MonMotha | well, Dallas does have a royalty free 1-wire core, so that isn't surprising |
| 02:14.05 | prpplague | g1powermac_PB better with the nail board |
| 02:15.15 | g1powermac_PB | prpplague: if only the nail kit had an lcd and keyboard and battery system setup already |
| 02:16.32 | g1powermac_PB | thats why I like the zipit, its already ready to be used, well, once I get some decent software on it |
| 02:19.04 | prpplague | g1powermac_PB kind of defeats the purpose of the nail kit |
| 02:20.14 | prpplague | g1powermac_PB you can get a hammer board and a kits laptop together pretty easy and alot more power than the zipit |
| 02:20.35 | g1powermac_PB | hmm |
| 02:21.55 | prpplague | http://www.toysrus.com/product/index.jsp?productId=2340839 |
| 02:22.04 | prpplague | i've been meaning to build another one and document it |
| 02:27.02 | g1powermac_PB | hmmm |
| 02:31.51 | g1powermac_PB | well, time for bed, gnight all |
| 02:45.07 | ce_geek | RobotGuy: You around? |
| 02:45.20 | RobotGuy | ce_geek: Yes |
| 02:45.36 | ce_geek | RobotGuy: Trying to understand the JFFS2 tutorial. Weren't there two at one point? |
| 02:45.57 | RobotGuy | ce_geek: No, just one. |
| 02:46.13 | ce_geek | It doesn't talk about how to actually create the JFFS2 image |
| 02:47.34 | RobotGuy | looks |
| 02:48.22 | RobotGuy | ce_geek: Hmmm, you are right! I will see about adding that tomorrow. |
| 02:48.31 | ce_geek | okay |
| 02:49.23 | ce_geek | RobotGuy: There's also a line there that says to "Replace <filesize>..." but "filesize" doesn't show up anywhere.... |
| 02:51.11 | RobotGuy | Corrected |

| 02:55.45 | ce_geek | Ah okay |
| 02:57.15 | RobotGuy | I just added definition of that. |

| 18:35.12 | prpplague | using a thumb drive as a rootfs is very easy |
| 18:35.26 | prpplague | no different than chrooting to internal flash |
| 18:35.49 | SpeedEvil | yeah. SD is faster though. (but not if you only bring out one line) |
| 18:35.59 | ds2 | but thumbdrives are a little bit more power hungry |
| 18:36.04 | RobotGuy | prpplague: Could I still do it with a modular kernel where I have usb-storage and the scsi stuff built as modules? |
| 18:36.08 | prpplague | SpeedEvil: sd is only faster if you have dedicated sd controller |
| 18:36.20 | SpeedEvil | prpplague: which the sc2410 does |
| 18:36.30 | ds2 | but is not brought out on the hammer ;) |
| 18:36.32 | SpeedEvil | prpplague: or at least - I get 3M/s on my phones microSD. |
| 18:36.41 | prpplague | RobotGuy: yea, you just use a standard initrd |
| 18:36.57 | RobotGuy | prpplague: That's what I thought. |
| 18:37.12 | prpplague | SpeedEvil: that sounds about right for a spi controller |
| 18:38.16 | SpeedEvil | Yeah - the card gets 12M/s on a USB2 controller |
| 18:38.21 | RobotGuy | I'm still going to have to have at least one hub on my robot though, because I also want to use some Phidgets. I need to get the Phidgets library ported into buildroot. |
| 18:39.16 | prpplague | tusb2046 is plenty good, and easy to implement |
| 18:39.18 | Dr{Who} | morning. |
| 18:39.43 | prpplague | Dr{Who}: greetings |
| 18:39.53 | SpeedEvil | prpplague: Or there are lots of hub boards that are 2cm*3cm or so, if you're feeling lazy. |
| 18:40.06 | prpplague | SpeedEvil: url? |
| 18:40.23 | SpeedEvil | url? |
| 18:40.27 | SpeedEvil | oh |
| 18:41.01 | prpplague | SpeedEvil: you mean take a board from a generic hub? |
| 18:41.05 | SpeedEvil | yes |
| 18:41.26 | prpplague | ahh |
| 18:41.48 | prpplague | SpeedEvil: we have a tusb2046b board we are going into production for |
| 18:41.54 | SpeedEvil | that works too |
| 18:42.14 | prpplague | its 1.7x1.7 |

| 18:44.23 | prpplague | interesting |
| 18:44.40 | prpplague | SpeedEvil: well the tusb2046b board we've got is designed for intergration |

| 18:45.23 | SpeedEvil | yeah - it's not quite so easy to use. |
| 18:45.50 | prpplague | ds2: no, its more in the style of the breakout boards from SFE |
| 18:46.39 | RobotGuy | prpplague: Is that board something that could stack with the Hammer-RDP? |
| 18:46.55 | prpplague | RobotGuy: possibly |

| 18:47.19 | prpplague | SpeedEvil: thats just 1.50 quid |
| 18:50.11 | prpplague | i've got a couple of these - http://www.geeks.com/details.asp?invtid=BLU-CX-H2042A&cpc=SCH |

| 18:53.02 | prpplague | looks |
| 18:53.12 | ds2 | "sturdy custom ABS case"? ;) |
| 18:53.17 | ds2 | (legos are ABS, AFAIK) |
| 18:53.36 | prpplague | SpeedEvil: yea same chip as the one in the blue case |
| 18:53.41 | g1powermac | yay, qtopia at least tried to use the scratchbox toolchain before erroring out ;-) |
| 18:53.55 | SpeedEvil | I need to measure the current use of those, and comapre to the tusb. |
| 18:54.11 | prpplague | SpeedEvil: what makes that one bigger is the external power support |
| 18:54.15 | SpeedEvil | yeah |
| 18:54.55 | prpplague | really if i wanted to make a supper small hub, you code to it pretty darn small and just add some .1" headers |
| 18:55.02 | SpeedEvil | yeah. |
| 18:55.07 | prpplague | lets seee |
| 18:55.36 | prpplague | (2x5)+gnd+3.3 = 12 pins |
| 18:55.49 | RobotGuy | prpplague: Anything LEGO catches people's eyes usually. |
| 18:56.09 | prpplague | you could do 4 pins on each side of a square board |
| 18:56.56 | RobotGuy | prpplague: I'd like to have a hub right on the Hammer-RDP, but I think that is going to have to be left for a stack board. |
| 18:57.22 | prpplague | RobotGuy: no reason you couldn't have one, we use one directly on the nail board |
| 18:57.31 | prpplague | biggest hassle is the 6mhz xtal |
| 18:57.52 | RobotGuy | prpplague: I'm not sure if the board space will be available. I'll have to check with Sienna on that again. |
| 18:58.20 | ce_geek | laughs at his co-worker having crashed his RC airplane, and decides that maybe it's not a good platform for a hammer experiment. |
| 18:58.27 | ds2 | speaking of hubs, anyone make one with just mini connectors? |
| 18:58.44 | SpeedEvil | ce_geek: I've designed an electronics housing for my UAV. |
| 18:58.50 | prpplague | ce_geek: hehe |
| 18:59.02 | prpplague | ds2: i've not seen any commercial ones |
| 18:59.18 | ce_geek | SpeedEvil: Cool! Airplane or heli? I love helis, but not real anxious to automate mine yet. |
| 18:59.32 | ce_geek | er autonomate or... whatever :) |
| 18:59.33 | SpeedEvil | ce_geek: it's got a fiberglass egg shape, filled with foam. On the outside, it's got EPP foam. |
| 18:59.47 | SpeedEvil | It's designed to take an impact at 50MPH |
| 18:59.48 | ohsix | you guys see this? wireless jtag http://www.sparkfun.com/commerce/product_info.php?products_id=8684# |
| 18:59.50 | ds2 | prpplague: it would be a nice accessory for a PDA... mini connectors + a local power source |
| 18:59.52 | ce_geek | Cool |
| 19:00.04 | SpeedEvil | ce_geek: http://www.mauve.plus.com/test.png |
| 19:00.26 | RobotGuy | ce_geek: We should add "autonomate" to the dictionary! ;) |
| 19:00.28 | SpeedEvil | ce_geek: bad render. Basically a thrust-vectored platform, optimised for _rapid_ vertical climb. |
| 19:00.59 | ds2 | SpeedEvil: that looks like those flying foam disk they are selling |
| 19:01.02 | prpplague | ohsix: interesting product, but i hardly find that something that is practical |
| 19:01.57 | SpeedEvil | ds2: It's designed to fly to 1-4Km in 3-4 mins. |
| 19:02.14 | SpeedEvil | ds2: then fly back down to the ground. |
| 19:02.18 | ds2 | SpeedEvil: that is a bit faster those |
| 19:02.34 | SpeedEvil | and land controlled. |
| 19:02.53 | SpeedEvil | Which is unfortunately the hard part. |

| 19:04.58 | ds2 | http://www.dealextreme.com/details.dx/sku.3781 |
| 19:05.22 | SpeedEvil | Naah. It's got >20 sensors. |
| 19:05.32 | SpeedEvil | And a peak power of some 400W |
| 19:05.48 | SpeedEvil | And hopefully will generate a 100MP panorama. |
| 19:05.54 | ds2 | how big is it? |
| 19:05.58 | SpeedEvil | 1Kg |
| 19:06.07 | ds2 | size wise |
| 19:06.15 | SpeedEvil | 25cm across. |
| 19:06.27 | ds2 | that's not too big |
| 19:06.30 | SpeedEvil | No. |
| 19:06.44 | SpeedEvil | it's aimed at surveyors, taking it to site in a suitcase. |
| 19:08.04 | ce_geek | SpeedEvil: Any videos? |
| 19:08.09 | ds2 | I'll be happy if I can get something like that to take a picture and return to me |
| 19:08.14 | SpeedEvil | ce_geek: it's still unconstructed yet. |
| 19:08.18 | ce_geek | SpeedEvil: Ah okay. |
| 19:08.25 | SpeedEvil | ds2: sale price looking like $1000ish |
| 19:08.38 | SpeedEvil | Minimum. |
| 19:08.43 | ce_geek | SpeedEvil: I'm looking into aerial photography with RC Helicopters. Trying to figure out if I can at least break even with the hobby. |
| 19:09.03 | ds2 | ce_geek: you too? |
| 19:09.10 | ce_geek | Wondering about liability stuff |
| 19:09.25 | ds2 | SpeedEvil: that isn't that expensive |
| 19:09.40 | ds2 | a RC heli of decent size is about half to almost that much |
| 19:09.50 | SpeedEvil | ds2: if you want it absolutely automated, it is. |
| 19:10.03 | ce_geek | ds2; Yea :) I've owned an e-flite Blade CX, and I have a Blade CP Pro now (not very fond of it.) I'd like to get a Hirobo Freya or a Thunder Tiger Raptor .90 this summer. |
| 19:10.19 | SpeedEvil | ds2: and able to do one panorama every 20 mins with little or no user interaction other than looking at the pictures. |
| 19:10.24 | ds2 | ce_geek: can you fly all those and land them? |
| 19:10.35 | ce_geek | ds2: The two electric helis yes. |
| 19:10.42 | ds2 | SpeedEvil: what's the price range for a fully automated setup? |
| 19:10.44 | ce_geek | ds2; I have not had an opportunity to fly larger birds. |
| 19:11.00 | ds2 | ce_geek: are the CX/CP the ones with the twin counter rotors? |
| 19:11.05 | SpeedEvil | ds2: there is nothing direclty comparable that I've seen even at $10K |
| 19:11.21 | SpeedEvil | ds2: pricing is hard. |
| 19:11.29 | ds2 | SpeedEvil: so what's on the $1K platform then? |
| 19:11.38 | ce_geek | ds2: The CX has coaxial blades, the CP does not. CP can fly inverted. I can't do that with it, and I won't be trying. It's a cheap helicopter with a crappy radio. I'll probably just sell it and get a T-rex |
| 19:11.53 | sjhill | wants to do model jets |
| 19:12.15 | ds2 | ce_geek: heh I see. I been looking at some version of the dragonfly |
| 19:12.18 | SpeedEvil | ds2: camera, large motor, several servos, about 20-30 sensors, and _lots_ of sensor fusion code, laser ranger, camera, 802.11a link, 433Mhz, ... |
| 19:12.23 | ds2 | cheaper then either the CX/CP |
| 19:12.49 | ds2 | SpeedEvil: that is pretty good for $1K... what's the $9000 extra get you? just automation? |
| 19:13.15 | SpeedEvil | ds2: profit! |

| 20:53.12 | ce_geek | Where does "SAC" come from in "ttySAC0"? |
| 21:02.38 | prpplague | ce_geek: i'm guessing its from "Samsung Async Controller |
| 21:05.34 | ce_geek | prpplague: Ah |
| 21:06.04 | ce_geek | prpplague: Are there serial pins on the hammer that show up in /dev? |
| 21:06.32 | SpeedEvil | the serial ports do |
| 21:06.39 | ce_geek | prpplague: I'm looking now, just figured you'd know off hand |
| 21:06.49 | ce_geek | K |
| 21:06.52 | ce_geek | Trying to find my schematic |
| 21:07.20 | SpeedEvil | or rather - the nodes in /dev provide device numbers to software so it can talk to the kernel drivers for the serial ports. |
| 21:07.36 | ce_geek | yeah, okay. Good. |
| 21:08.00 | ce_geek | Ah there we go, pins one and two. |
| 21:08.34 | ce_geek | looks like I can just hook this 1-wire temp sensor to the TX and RX pins and tell digitemp which port to use and it might.... work. |
| 21:08.37 | prpplague | ce_geek: yea, ttySAC0 and ttySAC2 are available on the hammer |
| 21:08.47 | prpplague | ce_geek: yea, you could use ttySAC2 |
| 21:08.58 | prpplague | ce_geek: you really should leave SAC0 for console |
| 21:09.05 | ce_geek | prpplague: How do I learn which pins that maps to? |
| 21:09.10 | ce_geek | Why isn't there ttySAC1? |
| 21:09.28 | ce_geek | other than intuition, just curious how I'd figure that out. |
| 21:09.38 | prpplague | ce_geek: 2 == uart 2 |
| 21:09.54 | ce_geek | prpplague: I suppose that's enough. |
| 21:09.58 | prpplague | ce_geek: ttySAC1 wasn't brought out on the hammer |
| 21:10.21 | prpplague | ce_geek: you can look at the dmesg for the serial port enumeration |
| 21:10.26 | ce_geek | Okay, but Linux can see it and thus creates a device node for it? |
| 21:10.35 | ce_geek | prpplague: Ah okay that's a good idea. |
| 21:10.48 | prpplague | ce_geek: well actually the device node is generated by default in buildroot |
| 21:10.51 | prpplague | ce_geek: but yea |
| 21:11.24 | prpplague | ce_geek: actually that gives me idea for the next version of the hammer, do a loop back on ttySAC1 , so you can do testing |
| 21:11.28 | prpplague | makes a note |
| 21:11.30 | ce_geek | prpplague: Okay I'm getting into some vocabulary issues then :) |
| 21:11.47 | ce_geek | prpplague: Good stuff to be specific about though. |
| 21:11.48 | prpplague | ce_geek: ok, how can i clarify |
| 21:11.51 | ds2 | prpplague: I think you need a board pin mux :) |
| 21:12.08 | prpplague | ds2: yea we discussed using a cpld or even 0 ohm resistors |
| 21:12.29 | ce_geek | prpplague: No, you're being clear. I'm just learning about what's called what and what created what. kernel vs. buildroot and what exactly is defined by "device node" etc. Just trying to be careful. |
| 21:12.44 | prpplague | ahh right |
| 21:13.28 | ce_geek | Okay so /dev/ttySAC2 should map to RXD2 and TXD2? |
| 21:13.41 | prpplague | ce_geek: you have the actually hardware (uart 0), you have the kernel driver (s3c24xx uart driver) and then you have the file system access to the kernel represented by a file (ttySAC0) |
| 21:13.58 | prpplague | ce_geek: correct, if they are configured for uart functionality |
| 21:14.09 | ce_geek | prpplague: Yeah. That's a good way to break it down. |
| 21:14.40 | ce_geek | prpplague: Well, I'm hoping "digitemp" will worry about that. Looks like just a configuration file, you specify the serial port and then just run the program. |
| 21:14.50 | prpplague | yep |
| 21:14.57 | prpplague | i read over some of it last night |
| 21:15.18 | ce_geek | Hopefully it's that simple. If that works I'd like to write some code to do it on my own too just to go through the motions. |
| 21:15.57 | ce_geek | Today I got the boards mounted on a piece of plexiglass. Tonight or early tomorrow i've got to solder some headers and build a ribbon cable to go to the bread board for lazy prototyping. |
| 21:17.22 | ce_geek | Looking to figure out why the WRT project needed a MAX233 chip |
| 21:18.34 | ds2 | prpplague: no PLD, please!! |
| 21:19.47 | prpplague | ce_geek: that does level shifting from ttl levels to rs-232 |
| 21:19.50 | ds2 | PLD's eat too much power |
| 21:20.02 | prpplague | ce_geek: the hammer carrier board has the levels already shifted |
| 21:20.13 | ce_geek | prpplague: Yeah, didn't see that I'd need one. |
| 21:20.16 | prpplague | ce_geek: you can access them on the J6 connector |
| 21:20.28 | g1powermac | woot, I think i found the problem with the qtopia cross-compiling issue |
| 21:20.42 | g1powermac | looks to be something funky going on between uclibc and qtopia |
| 21:21.07 | ce_geek | prpplague: The RX and TX pins should be 3.3V, right? |
| 21:21.18 | ce_geek | prpplague: So as long as the DS1820 is happy with that.... shouldn't it be fine? |
| 21:21.18 | g1powermac | http://www.busybox.net/lists/buildroot/2007-September/005300.html |
| 21:21.47 | prpplague | ce_geek: the rx/tx pins after the level shifter will be either -10 or +10 |
| 21:22.17 | ds2 | +/-10V IFF you give it +5V.. the 3.3V ones seem to peg out at about +/-6V |
| 21:22.18 | prpplague | ce_geek: you got the url for the wrt project one handy? |
| 21:22.28 | prpplague | ds2: ahh |
| 21:22.29 | ce_geek | prpplague: Ok. I'll look at the schematics for the carrier board and the DS1820 either later tonight or tomorrow. I've got to run for now. Thanks for your help. |

| 21:23.36 | ds2 | with the prices of the DS1820, I wonder if it is cheaper to add one of the smaller MSP430's and run it as a slave device |
| 21:24.17 | prpplague | ce_geek: you will need to access the txd/rxd prior to the level shifter |
| 21:24.31 | prpplague | ce_geek: the wrt page shows they are using ttl levels not rs-232 levels |
