| 00:26.44 | solar | prpplague: ok set that beer down for a sec and riddle me this. Is there anyway I can control the 4th led. The main power one. |
| 00:47.17 | prpplague | sorry no its tied to the main power |
| 00:47.22 | prpplague | looks at the schematic |
| 00:47.58 | prpplague | solar you could make a minor mod to the board |
| 00:48.07 | solar | ya? |
| 00:48.18 | prpplague | solar yea, you'd need a soldering iron :) |
| 00:48.50 | solar | the reason I'm after that led is my driver works better on a led thats on all the time vs one thats off. |
| 00:49.20 | prpplague | not sure i understand |
| 00:49.51 | solar | prpplague: cuz it's on all the time. One can tell if a hard lock happens cuz it's stop pulsing. |
| 00:50.16 | prpplague | ahh i see |
| 00:50.29 | prpplague | checks the schematic again |
| 00:52.11 | prpplague | so what you want is for a hard lock or reset to cause the led to stay on |
| 00:53.14 | ds2 | visual watchdog? |
| 00:53.22 | solar | pretty much. |
| 00:53.39 | solar | heartheat timer works ok. But I'm using the CPU idle time to drive the events |
| 00:53.58 | prpplague | you can solder a wire from a gpio to pin2 of d1 |
| 00:54.53 | prpplague | probably need a one 1k resistor though |
| 00:55.10 | solar | oh heh. I just noticed for the first time there is another PB on that side of the carrier |
| 00:55.41 | prpplague | yea thats the reset button |
| 00:56.34 | prpplague | we could mod the two leds with 1k pull downs |
| 00:57.01 | prpplague | pretty easy mod |
| 00:57.06 | solar | the two? |
| 00:58.11 | prpplague | yea, use a 1k pull down there |
| 00:58.49 | prpplague | example would be one end of R33 to ground via a 1k resistor |
| 00:58.54 | solar | two leds on that side of the board? GPH0=led0/hammer GPH1=led1/nail GPC12=led2/nail |
| 00:59.06 | prpplague | yea |
| 00:59.26 | solar | are the only ones I know of. Plus the one for power that we can't access without a few hacks for which I don't own the parts |
| 00:59.34 | prpplague | GPH0 would be easy to tweak |
| 01:00.37 | prpplague | checks the schematic again |
| 01:01.49 | solar | prpplague: thats ok. I've not had a soldering iron in my house in a very long time. |
| 01:02.16 | prpplague | hehe, i think you could get away with just a single wire to ground |
| 01:02.22 | solar | I'd probably melt the nail. especially at the micro size |
| 01:02.28 | prpplague | hehe |
| 01:02.59 | prpplague | solar i'm used to mod'n everything |
| 01:03.31 | prpplague | solar i'll test first thing in the morning |
| 01:03.32 | solar | oh. I might of found a canidate for the other nail. |
| 01:03.37 | ds2 | hands a solar an oxyacetylene torch to melt the nail ;) |
| 01:03.48 | solar | I do own one of those :) |
| 01:03.52 | prpplague | solar oh yea? met a cute girl at the nudie bar? |
| 01:04.20 | solar | prpplague: naa. co-worker who is kinda a retired hardware baby hacker |
| 01:04.34 | ds2 | are there non cute girls at the nudie bar? ;) |
| 01:04.45 | solar | yes. But I don't tip them |
| 01:04.50 | prpplague | hehe |
| 01:05.22 | prpplague | solar i'll make a note for the nail board leds |
| 01:05.26 | prpplague | test tomorrow |
| 01:05.47 | prpplague | solar don't know anyone handy with a soldering iron? |
| 01:06.06 | solar | prpplague: oh I'd be fine really. |
| 01:06.18 | solar | was pricing some other last night infact |
| 01:06.34 | solar | problem is I already want a nice one vs a black and decker pos one |
| 01:06.52 | prpplague | hehe |
| 01:07.01 | solar | oh yeah. here is the driver base. |
| 01:07.02 | solar | http://dev.gentoo.org/~solar/embedded/tct/nail-leds.c |
| 01:07.24 | solar | I don't expect it's proper like or anything yet. The GPIO logic might hurt your head |

| 01:30.19 | prpplague | bonus? whats that? |
| 01:30.45 | prpplague | is that something similiar to this "vacation" that i hear people talking about? |
| 01:30.51 | solar | it's something I'm told I get when I refer somebody and we end up hiring them. |
| 01:31.08 | solar | it's the first time I've seen one and about the 4th person I've recomended |

| 01:36.59 | prpplague | solar those smd or thruhole? |
| 01:37.29 | prpplague | tries again to pull up the page |
| 01:38.35 | prpplague | weird,i can pullup halted.com but not that page |
| 01:40.39 | prpplague | solar oh, those are resistor packs, its like 4 or 8 resistors in a single package |
| 01:41.06 | prpplague | solar those are for doing surface mounted designs where you use alot of the same resistor value |
| 01:41.14 | prpplague | solar you can see some on the hammer board |
| 01:41.44 | solar | page load failure for me now also. |
| 01:43.40 | prpplague | wow they are expensive on resistors |
| 01:44.04 | prpplague | i like jameco for getting resistor and cap kits |

| 02:17.27 | prpplague | solar think you need two nics? |
| 02:17.36 | prpplague | solar we were going to do just one 10baseT |
| 02:17.56 | prpplague | solar we figured you could plug some more usb->ethernet adapters in |
| 02:18.42 | solar | 2 nics? naa. For lots of nics the vendor routerboard.com is the vendor of choice |
| 02:19.10 | solar | again damn mips chips #% |
| 02:19.15 | prpplague | yea thats alot like what we had planned |
| 02:19.16 | solar | nice anyway |
| 02:19.50 | prpplague | two uarts, couple of leds, couple of push buttons, buzzer, 10baseT , 4 port usb hub |
| 02:19.58 | prpplague | microsd card slot |

| 02:27.21 | prpplague | i'm pretty sure i can fit it into an altoids case with what we have now |
| 02:27.48 | Mirell | Oh, that reminds me. I really got to freaking build that Altoids USB charger. |
| 02:28.49 | solar | prpplague: I happen to like minisd more than microsd.. But thats probably cuz don't own anything thats micro |
| 02:29.32 | prpplague | Mirell we've been talking about that to power the nail board |
| 02:29.35 | Mirell | prpplague: Ahh |
| 02:30.03 | prpplague | solar we just bought a giant stock of microsd sockets for the M8050, so most likely thats what we would use |

| 16:27.25 | solar | I can tell you. For me. I'd buy such a device. First 3 things I want to it. Take the hacker safe area and see if a 9V can fit in there side ways (if it does then super win). Then put one of those little trickle charing solar panels on top. |
| 16:27.46 | solar | then debate on finding a tft and seeing if it can be made to stick to the underside of the lid |
| 16:28.00 | prpplague | solar: interesting |
| 16:28.12 | prpplague | solar: not sure i understand the need for the battery power |
| 16:28.52 | solar | portable being handy |
| 16:29.19 | prpplague | but if you are plugging in an ethernet cable, its not exactly portable |
| 16:29.19 | solar | I carry around the nail with me pretty much everywhere I go. It's a conversion peice |
| 16:29.30 | prpplague | hehe |
| 16:30.01 | prpplague | i guess it boils down to either it being a wired or wireless |
| 16:30.03 | solar | Sure when I'm somewhere that has eth |
| 16:30.32 | RobotGuy | votes for wireless |
| 16:30.53 | solar | ya.. Think of landly being on wireless when at the local startbucks hacking away on a driver or two |
| 16:30.54 | RobotGuy | There are lots of free hotspots available |
| 16:30.54 | prpplague | solar: wouldn't be better to just use a usb->ethernet adapter in that case? |
| 16:31.26 | prpplague | solar: i really didn't want this to duplicate some of the stuff for the nail |
| 16:32.14 | prpplague | solar: just a note, the 9v batteries have higher voltage, but alot less current, so using two AA's would be better |
| 16:34.06 | solar | works for me. I've got 20 of the the 2500mAh ones. |

| 17:09.54 | RobotGuy | prpplague: After I try writing my image and reboot Hammer, it's not all there. |
| 17:10.21 | RobotGuy | prpplague: 3.6 MB gets written out of 11 MB. |
| 17:10.31 | prpplague | RobotGuy: writting via apex? |
| 17:10.37 | RobotGuy | prpplague: Yes |
| 17:10.54 | prpplague | RobotGuy: pastebin your commands |
| 17:10.56 | RobotGuy | prpplague: Following our JFFS2 howto |
| 17:11.50 | prpplague | one sec |
| 17:11.56 | RobotGuy | OK |
| 17:11.59 | prpplague | tries to calm down |
| 17:12.37 | RobotGuy | prpplague: I am sorry about your uncalmness. This can wait - don't want to add more stress to you. |
| 17:14.18 | prpplague | RobotGuy: ok so you erased the flash with: erase nor:1280k+0x00ec0000 |
| 17:14.21 | prpplague | RobotGuy: correct? |
| 17:14.38 | prpplague | RobotGuy: how big is your jffs2 image again? |
| 17:14.54 | RobotGuy | prpplague: Yes, I erased with that command. 11 MB. |

| 17:17.00 | prpplague | RobotGuy: correct? |
| 17:17.20 | RobotGuy | prpplague: Yes, as per the JFFS2 howto |
| 17:17.35 | prpplague | RobotGuy: the max size you can transfer to that space is 8MB |
| 17:17.46 | prpplague | RobotGuy: you'd need to alter the base address if you are going bigger |
| 17:17.49 | prpplague | looks |
| 17:17.55 | RobotGuy | prpplague: I have done 11 MB images before on another Hammer. |
| 17:18.19 | prpplague | RobotGuy: are you certain of that? |
| 17:18.27 | RobotGuy | prpplague: Only 3.6 MB gets written. |
| 17:18.37 | RobotGuy | prpplague: Yes, I am certain. |
| 17:18.46 | prpplague | RobotGuy: 11-8= 3 |
| 17:19.04 | prpplague | RobotGuy: what happens is the sdram wrapps on the address space |
| 17:19.19 | prpplague | RobotGuy: the top 3mb is in a space area where there is no adram |
| 17:19.52 | RobotGuy | prpplague: OK, so what address should I be uploading the image to? I will change it in the howto. Must be able to fill flash. |
| 17:20.12 | prpplague | one second |
| 17:20.15 | RobotGuy | OK |

| 17:30.46 | prpplague | solar: i was thinking of swapping the connectors to the other end |
| 17:32.09 | solar | on the side? |
| 17:32.11 | sunrunner20 | does nfs has a last accessed property? |

| 17:44.00 | sunrunner20 | delete the rest |
| 17:48.22 | ds2 | Did I see a 2AA powered hammer becoming a reality? |
| 17:52.47 | solar | ds2: I think so. It's time tincantools releases a hacker friendly portable unit that actually lives in a tincan. What I'm hiting towards for a layout. http://rafb.net/p/OPfhcT83.html |
| 17:52.59 | solar | got ideas? flood prpplague with them :) |
| 17:53.31 | RobotGuy | solar: Wouldn't there be a heat issue with hammer in such a small case? |
| 17:53.46 | solar | ARM + Heat is a problem? |
| 17:53.55 | CosmicPenguin | especially in summer |
| 17:54.01 | CosmicPenguin | use deodorant |
| 17:54.06 | RobotGuy | solar: I don't know. I am just wondering. |

| 18:10.05 | ds2 | solar: I been pesting him from the start for a 2AA friendly version |
| 18:11.41 | RobotGuy | ds2: You are good at that. :P :) |

| 18:13.10 | sunrunner20 | know what would be cool |
| 18:13.16 | sunrunner20 | if my C: drive was really two hdds |
| 18:13.26 | sunrunner20 | and it magically detected how to split the load between them |
| 18:13.35 | ds2 | get a raid controller :P |
| 18:13.37 | sunrunner20 | no |
| 18:13.43 | sunrunner20 | NOT Raid 0 style |
| 18:13.53 | sunrunner20 | more like LVM style |
| 18:14.09 | sunrunner20 | where data would end up on the second drive instead of the first |
| 18:14.24 | sunrunner20 | hates raid0 with a passion |
| 18:15.13 | solar | ds2: then does a design something like that seem ideal for ya? aka the altoids form facor. |
| 18:15.36 | ds2 | solar: not w/o PM |
| 18:15.37 | prpplague | RobotGuy: please post your log |
| 18:15.53 | prpplague | solar: should the microsd be accessable from the outside of the case? |
| 18:15.54 | solar | PM = ? power mgmt? |
| 18:15.59 | ds2 | *nod* |
| 18:16.06 | solar | prpplague: yes. |
| 18:16.20 | solar | prpplague: no chance to make the power light a green one is there? |
| 18:16.23 | prpplague | solar: so without openigng the lid |
| 18:16.29 | ds2 | 2AA alkaline has very limited life w/o PM |
| 18:16.44 | prpplague | solar: sure |
| 18:16.58 | solar | never tested it. But does cpufreq stuff help much on arm? |
| 18:17.08 | ds2 | PM is more then CPUfreq |
| 18:17.15 | prpplague | solar: yea, looks likes i'll have to cut the lid to do the rj45 |
| 18:17.16 | RobotGuy | prpplague: http://rafb.net/p/7e5d9N16.html |
| 18:17.24 | solar | ya I'm sure. But it was more a general question |
| 18:17.27 | ds2 | should be able to shut off blocks that are not needed (powerdown + cut off clock) |
| 18:17.44 | ds2 | but yeah, cutting down CPU clock helps |
| 18:18.07 | solar | ds2: not sure but it actually looks like 3 could fit in there |
| 18:18.29 | ds2 | solar: then you are depending on a very efficient switcher |
| 18:18.41 | ds2 | I rather see PM to squeeze out the last bit of usage |
| 18:18.59 | solar | is this a limitation to the hammer in your eyes currently? |
| 18:19.14 | ds2 | that and its size... too high |
| 18:20.04 | ds2 | I want to get maybe 2-3 days of usage on a single pair of AA's |
| 18:20.05 | solar | the size of the tin or the hammer itself when used with the 40pin DIP long prongs? |
| 18:20.07 | prpplague | RobotGuy: how do you know your jffs2 image is 11mb? |
| 18:20.37 | solar | RobotGuy: btw. The image I made for ya last night that we did not get to test properly was about 6M |
| 18:20.47 | RobotGuy | prpplague: -rw-r--r-- 1 robotguy staff 11M 2008-06-26 20:50 hammer.testing.kernel-2.6.26-rc7.rootfs.jffs2 |
| 18:21.00 | ds2 | solar: the hammer itself... ideally, it should have a flat bottom and J leads instead of the pins + no or optional JTAG pins on top; a board edge connector would be nice |
| 18:22.20 | prpplague | RobotGuy: so how do you know not all of your image is there? |
| 18:22.27 | prpplague | RobotGuy: are there files missing? |
| 18:23.00 | prpplague | RobotGuy: try generating a small rootfs image for testing |
| 18:23.11 | RobotGuy | prpplague: Look at the very last of the log where I did "df -h" - it shows only 3.6 MB used on the flash. |
| 18:23.23 | prpplague | RobotGuy: that doesn't mean anything |
| 18:23.55 | RobotGuy | prpplague: How does that not mean anything? It should show the size of the used and unused space. |
| 18:24.05 | ds2 | solar: if you are in a hurry to do the rework, I might be able to help |
| 18:24.14 | prpplague | RobotGuy: it does not relate to the jffs2 image file size |
| 18:24.19 | ds2 | (the LED thingie from yesterday) |
| 18:25.01 | RobotGuy | prpplague: commands are missing that should be there, like "python" |
| 18:25.06 | prpplague | RobotGuy: ok |
| 18:27.05 | prpplague | RobotGuy: i don't know at the momment, i'd have to check the buildroot dir to see if the sizes match |
| 18:27.29 | RobotGuy | prpplague: The sizes should match. They always have in the past. |
| 18:28.02 | RobotGuy | prpplague: I've recreated your account on my system. |
| 18:28.04 | prpplague | RobotGuy: go to buildroot/project_build_arm/Hammer/root |
| 18:28.13 | prpplague | RobotGuy: do: du -hs |
| 18:28.47 | RobotGuy | > du -hs |
| 18:28.47 | RobotGuy | 106M . |
| 18:28.59 | solar | ds2: I'm in no hurry really. tbh I'm just throwing out ideas to prpplague.. And see what he bites on. |
| 18:29.44 | prpplague | solar: trying to decide if i really want the enc28j60 inside on this one |
| 18:30.18 | RobotGuy | prpplague: The enc28j60 can generate a lot of heat. |
| 18:30.22 | prpplague | RobotGuy: uh what? |
| 18:30.24 | solar | prpplague: if you can do 4 USB it would be an ok trade off for not having ethX |
| 18:30.32 | prpplague | RobotGuy: 106mb? |
| 18:30.45 | prpplague | solar: yea thats easy |
| 18:30.52 | solar | however. ppl with windows have to go track down drivers usually to get usbnet working. |
| 18:30.56 | RobotGuy | prpplague: That's what it showed. |
| 18:31.00 | ds2 | No ethernet, please! |
| 18:31.03 | prpplague | RobotGuy: are you sure? |
| 18:31.06 | prpplague | ds2: ?? |
| 18:31.14 | ds2 | prpplague: power consumption |
| 18:31.25 | prpplague | ds2: sorry i'm slow today |
| 18:31.33 | RobotGuy | root@intrepid /devel/ARM9/Hammer/buildroot/project_build_arm/walter/root |
| 18:31.33 | RobotGuy | > du -hs |
| 18:31.33 | RobotGuy | 106M . |
| 18:31.36 | prpplague | ds2: please explain |
| 18:31.40 | ds2 | prpplague: <prpplague:#edev> solar: trying to decide if i really want the enc28j60 inside |
| 18:31.40 | ds2 | + on this one |
| 18:31.42 | solar | prpplague: one thing. Could it still be powered via usb (or the external power source) ? |
| 18:31.45 | prpplague | RobotGuy: ok thats part of your problem then |
| 18:31.54 | ds2 | ethernet is not exactly light on power consumption |
| 18:32.33 | prpplague | ds2: ok so you are against having ethernet on the altoids-hammer |
| 18:32.53 | prpplague | solar: yea i'll have a barrel jack for external power |
| 18:32.55 | solar | but are in favor of a 4 port USB hub being built directly into it? |
| 18:32.57 | ds2 | prpplague: yep. I am against anything that drains power significantly when using 2AAs |
| 18:33.20 | ds2 | besides a USB to Ethernet adapter can be used if it must be used |
| 18:33.32 | ds2 | the pegasus based ones seem to work just fine |
| 18:33.32 | prpplague | hmm, seems like you guys really want it portable |
| 18:34.04 | ds2 | that's as close as it'll get... I want to run off a day or two with a CR2032 |
| 18:34.06 | ds2 | :) |
| 18:34.21 | prpplague | wow |
| 18:34.26 | prpplague | ambitious |
| 18:34.40 | davidc__ | ds2 - hehe... I somehow don't quite think that the 0.3ma current source from the CR2032 will quite suffice to run a 200mhz processor.... |
| 18:34.49 | RobotGuy | Hammer needs a different connection method for JTAG. |
| 18:34.57 | prpplague | ds2: what is it you want to do? |
| 18:34.57 | solar | without a doubt I'd love to devel at home. Then w/o powering it down take it to work and put it back on usb power. |
| 18:35.02 | prpplague | RobotGuy: ?? |
| 18:35.03 | ds2 | davidc__: you can pull more that that |
| 18:35.21 | RobotGuy | prpplague: nvm. Just ignore me today. |
| 18:35.23 | ds2 | prpplague: ideally, I want it to be a watch type app where things are called up on demand |
| 18:35.35 | RobotGuy | fades into the background |
| 18:35.43 | prpplague | RobotGuy: whats up? |
| 18:35.55 | ds2 | so for now the closests would be a walkie talkie thing-- the Palm folks did stuff like this in the late 90's with a pair of AAA's and that ran for weeks |
| 18:36.12 | solar | ds2: then for power reasons. You also want the ability to toggle even the power led off right? |
| 18:36.14 | ds2 | so scaling it back a bit to a day or two on CR2032 isn't THAT unrealistic |
| 18:36.22 | ds2 | solar: yep |
| 18:36.26 | prpplague | solar: hmm, i think we are talking about different things |
| 18:36.34 | ds2 | solar: or have it be a bit of eink instead |
| 18:36.37 | davidc__ | ds2 - check the spec - they're not rated for much higher continuous, and I've used em before |
| 18:36.59 | ds2 | davidc__: I have used them in datalogger drawing about 5-10mA |
| 18:37.39 | davidc__ | ds2 - I;ve used em in a portable electronics app drawing about the same. THe batteries I had started dropping off in terms of output voltage as soon as you passed about 5 ma |
| 18:37.41 | ds2 | 1 pressure sensor, 1 ATTiny13 (I think), 1 EEPROM, 1 LDO, 2 CR2032 cuz I was too lazy to do a boost switcher |
| 18:38.08 | prpplague | RobotGuy_SNAFU: ?? |
| 18:38.10 | ds2 | davidc__: I didn't seen much of a drop off |
| 18:38.17 | prpplague | RobotGuy_SNAFU: talk to me buddy, whats going on? |
| 18:39.07 | prpplague | solar: i could put a small lcd in the lid |
| 18:39.23 | prpplague | solar: flip open the lid and you'd see the lcd |
| 18:39.39 | ds2 | davidc__: might be brand related... had some odd problem with a the cells I got in the field at a local drugstore |
| 18:40.09 | ds2 | the originals I used was the 0.25/each ones from bgmicro |
| 18:40.46 | davidc__ | ds2 - Yeah, I dunno what brand they were.. they were client supplied |
| 18:41.40 | solar | prpplague: While I love the idea. I think that might pass ds2's power requirements. Chances of leaving the headers there and having a known working model that ppl can pickup off of sparkfun.. It should keep the prices down |
| 18:42.21 | prpplague | solar: hehe, i have ds2 on ignore, hehe |
| 18:42.36 | prpplague | solar: i'm mainly thinking of eye candy for lwe |
| 18:42.40 | solar | oh |
| 18:43.02 | ds2 | :P FINE |
| 18:43.04 | prpplague | ds2: what is it you are wanting to do? |
| 18:43.52 | prpplague | solar: 4 usb host ports, 1 usb slave port, microsd |
| 18:44.02 | prpplague | solar: 2 leds, 1 pushbutton |

| 18:46.14 | prpplague | solar: indeed i have that bookmarked |
| 18:48.05 | prpplague | solar: yea my main question is what features to put in it |
| 18:48.36 | solar | if you add that. Then I'd really have to push for that audio |
| 18:49.08 | solar | no external USB audio sound cards is there? |
| 18:49.14 | prpplague | solar: if i add the lcd you want some audio? |
| 18:49.18 | prpplague | solar: yea there are a few |
| 18:49.38 | prpplague | solar: you'd want high quality sound? |
| 18:50.35 | solar | prpplague: I like the kitchen sink idea myself. |
| 18:50.46 | prpplague | solar: ?? |
| 18:51.45 | prpplague | solar: i figured with mp3 players so cheap that it wouldn't be that impressive to do audio |
| 18:52.46 | solar | prpplague: are we talking (mono being LowQuality) and stereo (being HighQuality) ? |
| 18:53.02 | prpplague | solar: also sample rate |
| 18:53.11 | prpplague | solar: are you wanting to play mp3's to listen to? |
| 18:53.53 | solar | prpplague: yes. |
| 18:55.06 | *** join/#edev prpplague^3 (n=dave@mail.americanmicrosystems.com) |
| 18:55.11 | solar | but if you are talking that mini display. Then it makes it a micro multimedia station. That alone proves that tct could be a suitable vendor for PDA's etc. |
| 18:55.49 | solar | also assuming you use the jackhammer type of hardware in there :) |
| 18:56.25 | prpplague | solar: yea, the difference between the hammer, and the jack/sledge hammer is that the hammer doesn't have i2s |
| 18:56.33 | prpplague | solar: the jack/sledge does |
| 18:56.43 | prpplague | solar: i could add a vs1002 to do mp3 decoding |
| 18:56.49 | prpplague | solar: http://www.sparkfun.com/commerce/product_info.php?products_id=519 |
| 18:56.53 | prpplague | solar: thats easy enough |
| 18:57.08 | davidc__ | prpplague - what processor is it gonna be running on? |
| 18:57.16 | davidc__ | prpplague - you can do mp3 decoding with even a low end arm |
| 18:57.18 | prpplague | davidc__: the hammer uses the s3c2410 |
| 18:57.33 | prpplague | davidc__: its not the decoding, its the output that is the issue |
| 18:57.43 | davidc__ | prpplague - oh, for audio output? |
| 18:57.47 | prpplague | davidc__: yea |
| 18:57.52 | solar | prpplague: not limited to mp3's. If you add that small display and the decent CPU/mem. Then it should be able to play encoded movies on airplane for your personal viewing pleasure. (just good luck getting on the plane with it) |
| 18:57.59 | davidc__ | no I2S output? |
| 18:58.03 | prpplague | davidc__: nope |
| 18:58.34 | davidc__ | prpplague - hrm... little memmapped cpld feeding an adc? |
| 18:58.38 | prpplague | solar: well i doubt TSA is going to let you have a altoids box on the airplane |
| 18:59.00 | davidc__ | especially an altoids box filled with "bomb parts" <- how they classify assorted electronics |
| 18:59.05 | prpplague | solar: it sounds like we are still talking about two different items |
| 18:59.18 | solar | prpplague: likewise.. But it would make a funny read on digg.com |
| 18:59.22 | prpplague | solar: you are more wanting a portable device that TCT will sell |
| 18:59.36 | prpplague | davidc__: hehe |
| 18:59.54 | solar | prpplague: I'd like to see you turn a profit from feedback I've given. |
| 19:00.16 | prpplague | solar: yea we plan on doing a pda platform |
| 19:00.18 | davidc__ | TSA Flowchart - Does it have wires. Y> Bomb parts N> Might be bomb parts |
| 19:00.32 | prpplague | solar: i was just trying to think of something i could put together for lwe |
| 19:00.44 | prpplague | davidc__: hehe |
| 19:00.50 | solar | prpplague: like a few models vs mass production? |
| 19:02.09 | prpplague | solar: yea, i'd only do quick turns of maybe 4 or 5 boards |
| 19:02.21 | prpplague | solar: just something i was doing myself |
| 19:02.38 | solar | oh in that case. Can I send ya a check for parts? |
| 19:02.46 | prpplague | solar: ?? |
| 19:03.20 | solar | prpplague: as in your only playing with this idea in your freetime. Ie it's not going to be a project at work? |
| 19:03.29 | prpplague | solar: correct |
| 19:03.44 | solar | if so. And you are buying these parts out of pocket. Then I'm offering to pay for the parts |
| 19:04.04 | prpplague | solar: for the altoid box design? |
| 19:04.08 | solar | yes |
| 19:04.14 | prpplague | hmm |
| 19:04.32 | prpplague | solar: well you tell me what you want on it, and i'll design it |
| 19:04.58 | solar | I wish google sketchup worked under linux |
| 19:05.23 | prpplague | solar: if you can just give me a list of what features are a must |
| 19:05.34 | prpplague | solar: and which ones are "would be nice" |
| 19:06.29 | prpplague | RobotGuy_SNAFU: ping |
| 19:07.00 | prpplague | solar: oh the most important question: regular or cinnamon altoids case? |
| 19:07.40 | solar | I think the cinnamon use a raised stamping |
| 19:07.59 | solar | so do the dark choclate ones. So the std one (which is flat) is ideal |
| 19:08.20 | prpplague | solar: hehe, both the cinnamon and regular ones i have are flat |
| 19:08.40 | solar | If you are going for the classic look and feel I'd think std |
| 19:08.58 | prpplague | solar: hehe agreed |
| 19:09.16 | solar | win ya more points when it gets covered on make/etc.. |
| 19:09.17 | prpplague | solar: ok, so you want it to be battery powered |
| 19:09.23 | prpplague | solar: 2XAA's |
| 19:09.28 | prpplague | solar: microsd |
| 19:09.38 | prpplague | solar: what else? |
| 19:09.41 | solar | I'm a fan of that. But we could also make it an altoids cluster. |
| 19:10.13 | prpplague | solar: yea, you could do 4xAA's in a seperate altoids can |
| 19:10.22 | prpplague | solar: or even 3 18650's |
| 19:10.37 | solar | How do the 18650's differ from AA? |
| 19:10.47 | prpplague | solar: lithium ion |
| 19:11.08 | prpplague | solar: much higher performance |
| 19:11.55 | prpplague | solar: the 18650 base voltage is around 3.7v whereas the AA is ofcourse around 1.3 |
| 19:12.24 | solar | Any existing cellphone batterys fit the bill? The whole recharable thing is a plus |
| 19:12.58 | prpplague | solar: yea you can use those, but most small camcorder batteries are better |
| 19:13.05 | solar | vs having to open it up. Remove and put back in. (thinking long term usage) |
| 19:13.09 | prpplague | solar: alot of those are based on 18650 |
| 19:13.32 | prpplague | solar: with 18650's you'd just recharge it in the case |
| 19:15.16 | solar | perfect. |
| 19:15.30 | solar | let me scroll back and see that audio chip you posted before. |
| 19:16.01 | prpplague | solar: 1.3v x 4 x 2500mAh = 13000w |
| 19:17.15 | prpplague | solar: 3.7v x 3 x 2500mAh = 27750w |
| 19:17.33 | prpplague | solar: about the same physical space |
| 19:18.06 | solar | brb watching this http://blog.makezine.com/archive/altoids_and_tin_cases/ |
| 19:21.36 | T0mW | prpplague: ahem, your decimal points are missing (2.775W) |
| 19:21.53 | T0mW | prpplague: doh 27.75W |
| 19:21.53 | prpplague | T0mW: oops sorry i meant mW |
| 19:22.00 | T0mW | heh |
| 19:22.17 | T0mW | I was thinking of how big that heat sink should be... |
| 19:22.24 | prpplague | T0mW: email mr.herod back? i know he is going to ask me later today |
| 19:22.31 | T0mW | will do |
| 19:22.53 | solar | prpplague: but for the real geeks. http://blog.makezine.com/tin1.jpg |
| 19:23.02 | prpplague | looks |
| 19:23.24 | prpplague | solar: whats inside that? |
| 19:23.35 | ds2 | prpplague: I'll elaborate later. "other stuff" needs addressing |
| 19:23.58 | prpplague | ds2: np |
| 19:24.04 | prpplague | ds2: when you have time |
| 19:25.50 | solar | prpplague: no idea. I was pointing you more at the penguin mint cans from http://www.peppermints.com/ (tux linuxish haha) |
| 19:28.04 | prpplague | solar: yea, had my share of those, hehe |
| 19:28.38 | prpplague | i'll probably go to target and get some tins, they have some tins identical to the altoids for hobby stuff |
| 19:28.40 | prpplague | unpainted |
| 19:29.02 | solar | to bad tin has such a low melting point. |
| 19:29.37 | solar | and it's hard to get copper to adhere to it. |
| 19:29.46 | solar | otherwise I can silver plate. |
| 19:30.12 | solar | gold plating could be done. But the chems to do it have a short shelf life. |
| 19:30.18 | solar | so I've avoid getting into that |
| 19:31.53 | prpplague | hehe |
| 19:32.31 | prpplague | solar: so talk to me, i've got the base schematic started |
| 19:32.55 | prpplague | solar: 40-pin dip for the hammer, 2 led/1 button header |
| 19:33.06 | prpplague | solar: barrel power connector |
| 19:33.10 | prpplague | solar: proto area |
| 19:33.29 | prpplague | solar: atleast 2 usb hosts |
| 19:33.42 | prpplague | solar: what about usb device port? |
| 19:36.44 | solar | devivce port is the B connector in the nail now? |
| 19:36.56 | prpplague | solar: yea |
| 19:37.26 | solar | works good. I like it. But a total of 5 USB's might be overkill? Or is it just the way it works best? |
| 19:47.44 | prpplague | solar: yea |
| 19:48.26 | prpplague | solar: the choices are, 4 usb hosts with 1 internal hub and a usb device, or 2 usb hosts with no hub and no device |
| 19:48.41 | prpplague | solar: the 2 usb hosts doesn't require any additional components |
| 19:48.52 | prpplague | solar: makes it small and easy |
| 19:49.42 | prpplague | solar: if all you want is just the device with a bunch of usb, thats really easy |
| 19:50.53 | prpplague | solar: what about uarts? |
| 19:51.15 | solar | I don't have a soild understanding of what exactly uarts are ;/ |
| 19:51.24 | prpplague | solar: hehe, serial ports |
| 19:51.27 | solar | <-- more of a software kinda guy.. (this the distro thing) |
| 19:51.46 | solar | usb serial is fine afaik |
| 19:53.44 | prpplague | solar: so what i'm hearing, is a small protoarea, the hammer socket, a usb hub with 4 ports, usb device socket, 2 leds, 1 push button, and a barrel power connector |
| 19:53.56 | prpplague | oh and microsd |
| 19:54.01 | solar | 4 ports would allow us to do. keyboard/mouse/wifi/storage/sound and with that tiny display you are planning. Everything should just be about there to play a movie of (say a tct commercial that explains the device and the services offered by tct/you) |
| 19:54.02 | chouimat|work | prpplague serial are nice |
| 19:54.31 | solar | chouimat|work: required or is that when it's best to take advantage of USB? |
| 19:55.10 | solar | prpplague: Oh. For questions I've not answered yet it's cuz I'm reading up on the topics and am thinking |
| 19:55.13 | chouimat|work | solar: I find them conveninent to have a debug console :) |
| 19:55.20 | prpplague | solar: np |
| 19:55.56 | prpplague | solar: hmm, on the lcd, i was thinking of having it on the inside of the lid, which means you'd have to open the case to view the lcd |
| 19:56.09 | prpplague | solar: i.e. the way you would open a laptop |
| 19:56.37 | solar | prpplague: yep. And I was thinking where the keys of a laptop are would be a flat black plastic barrier keeping you away from the hardware |
| 19:57.07 | solar | which you could hack up. drill holes in. Add more leds. Or other. |
| 19:57.28 | prpplague | solar: interesting, i was going to have it open for people to look at |
| 19:57.38 | solar | ~80 small push buttons for example :) |
| 19:57.56 | prpplague | solar: you just wont let it go will you? hehe |
| 19:59.19 | solar | prpplague: cuz you know I'm leading you up to leaving me space for the GM862 |
| 19:59.51 | prpplague | solar: hehe, well you need to share with your goals so i can account for that |
| 20:00.03 | solar | so yeah. My dream is this. |
| 20:00.15 | prpplague | solar: altoid case cell phone? |
| 20:01.30 | prpplague | solar: we i can add the lcd from sparkfun |
| 20:01.51 | prpplague | solar: what about a trackball? |
| 20:01.55 | solar | irda,camera,small inline hardware keyboard,touchscreen,(mini or micro sd), usb client+host ports,audio,bluetooth,speaker |
| 20:02.14 | solar | more or less. I'm naming off exactly what my existing HTC wizard is. But trying to make it open |
| 20:02.26 | prpplague | solar: yea, thats more like the pda reference design we are talking about doing |
| 20:02.46 | solar | my cell is only slightly larger than an altoids case |
| 20:03.31 | solar | I barely use bluetooh,irda so those are not required in my mental ideal umpc |
| 20:03.44 | solar | cam not required either. |
| 20:03.55 | solar | but w/o a touchscreen. You probably want that trackball |
| 20:04.28 | solar | if you are able to get X running. which sounds like you can. Then being able to faux that mouse is vital |
| 20:04.31 | prpplague | well for the pda reference we'd use a 240x320 display with touch |
| 20:05.05 | prpplague | solar: yea my trackball driver is completely functionaly now |
| 20:05.39 | solar | good job |
| 20:06.22 | solar | oh. btw you using eabi for that oe project@work ? |
| 20:13.07 | prpplague | solar: yea using eabi with poky |
| 20:14.29 | prpplague | solar: hmm, i'm thinking, i'm gonna do the small lcd from sfe, along with a pwm audio, two host connectors |
| 20:14.48 | prpplague | solar: microsd, some leds and some buttons |
| 20:15.11 | prpplague | solar: and maybe the trackball |
| 20:17.54 | prpplague | hmm maybe the trackball is too much |
| 20:19.56 | solar | fullsize leds? |
| 20:20.48 | prpplague | solar: yea probably |
| 20:21.32 | solar | In general (not for this project) but I really like the non defused leds used on the nail. To bad we don't see those done in grids like we do with the 10mm ones etc. |
| 20:22.45 | prpplague | ahh |
| 20:22.50 | solar | prpplague: track ball being omited is fine. Just means one could not move around the screen if X was running and using non tft |
| 20:23.31 | prpplague | solar: plug i a usb mouse, hehe |
| 20:23.36 | solar | yep |
| 20:23.44 | solar | made from another tin :) |
| 20:23.50 | prpplague | hehe |
| 20:23.59 | prpplague | i was thinking just a cheap o laptop one |
| 20:24.33 | prpplague | and a small usb numberic keypad |
| 20:24.57 | solar | yeah |
| 20:25.18 | prpplague | sitting on the table, have a couple of different screens with some audio |
| 20:25.34 | solar | take a pic of your work area |
| 20:25.44 | prpplague | solar: ?? |
| 20:26.08 | prpplague | for the screens? |
| 20:26.52 | solar | yeah. I'm curious what your work area looks like |
| 20:27.03 | mnemoc | too |
| 20:27.13 | prpplague | hehe, i don't have the camera handy but its a freakin disaster |
| 20:27.26 | chouimat|work | prpplague sound like my desk at home :) |
| 20:28.10 | solar | I love a disaster. Some pics of last place when I had room for a lab. http://dev.gentoo.org/~solar/batlab/ |
| 20:29.16 | prpplague | hehe |
| 20:29.24 | prpplague | i'll take a pic on monday |
| 20:30.39 | prpplague | solar: hmm, should i include a speaker for the audio or use a pair of external speakers, i.e. pc speakers? |
| 20:32.58 | solar | internal mono to replace the buzzer idea. And external stereo jack |
| 20:33.40 | prpplague | solar: the jack would be stereo for both speakers, but it still would be mono |
| 20:33.54 | prpplague | solar: this would be the low end audio |
| 20:34.04 | prpplague | 8khz sample rate |
| 20:34.21 | prpplague | its either that or add the vs1002 |
| 20:34.31 | prpplague | grabs the datasheet on vs1002 |
| 20:34.37 | solar | but it's enough to demo nearly every feature of the hammer that can be shoved in the smallest space you can |
| 20:35.21 | solar | well not that it's the hammer. But those working POC's are nice. |
| 20:37.28 | prpplague | solar: the vs1002 supports mp3 and wav |
| 20:37.42 | prpplague | wonders if there is a linux driver |
| 20:40.14 | prpplague | solar: http://alpmp3.sourceforge.net/main.php?id=net#VS |
| 20:45.09 | solar | little worried there at first. It says copy the .ko files. But never said to run make (which made me this binary blobs) |
| 20:45.16 | solar | but I see the source code d/l link |
| 20:46.15 | solar | question now becomes. Does that allow you to put a built in mic also? |
| 20:46.33 | solar | input source rather |
| 20:49.20 | prpplague | solar: yea the vs1002 does have mic, but i'd not use it for this project |
| 20:53.33 | prpplague | hmm |
| 20:53.37 | prpplague | vs1002 or not |
| 20:53.39 | prpplague | hmm |
| 20:54.12 | solar | as in add sound in or skip it? Or that chip vs another? |
| 20:55.31 | prpplague | use pwm or a vs1002 |
| 20:55.46 | prpplague | i want some audio(i think), just not sure about using the vs1002 |
| 20:57.22 | solar | I think the pwm one you just said is the link I never got around to looking at. And sadly don't see it in the scroll |
| 20:57.46 | prpplague | i don't think i listed anything about the pwm |
| 20:57.51 | prpplague | one sec |
| 21:01.13 | prpplague | solar: hmm no real good url's about doing pwm audio |
| 21:01.41 | prpplague | solar: short and sweet of it is you use a pwm controller, like whats on the hammer to generate square waves |
| 21:01.46 | solar | think thats more or less what cell phones use for speaker phone? |
| 21:02.01 | prpplague | solar: no the cell phones usually use a codec |
| 21:02.36 | prpplague | solar: this is super low end with the same rate |
| 21:02.50 | prpplague | solar: a good example are the greeting cards that play music |
| 21:02.54 | prpplague | solar: those use pwm |
| 21:03.43 | prpplague | solar: almost all of the kids toys that have audio such as learning laptop use pwm audio |
| 21:04.15 | prpplague | solar: ahh here is a good post - http://www.hackaday.com/2008/02/07/pwm-audio-generation-with-an-avr/ |
| 21:04.36 | solar | to bump it up to the vs1002 is looking like a problem cuz of [maybe additional coding time/cost/size/space/other]? |
| 21:05.43 | solar | size and space a little redundant.. But.. |
| 21:07.00 | prpplague | solar: size isn't really an issue, but adding the vs1002 does add complexity and cost |
| 21:10.39 | solar | prpplague: if you think this is a dead end design then I'd go with the pwm. If you think it could catch on. Then I'd consider the vs1002. |
| 21:11.41 | solar | but if there exists usb external sound cards. Then pwm all the way |
| 21:12.29 | solar | there used to exists usb touchscreens. But they seem to have died off. |
| 21:16.20 | prpplague | hmm |
| 21:16.30 | prpplague | solar: have to roll it around for a day or two |
| 21:28.29 | prpplague | cbrake: ping |
| 21:32.50 | prpplague | solar: the vs1002 might be more robust in the long run, but its definetly more expensive |

| 21:41.48 | davidc__ | is there no other bus method available that can stream data to an ADC? |
| 21:42.07 | davidc__ | for $20 for the chip, a CPLD stuck on a memory bus + an I2S DAC would be cheaper |

| 23:42.21 | prpplague | we could use those too |
| 23:42.50 | prpplague | http://www.geeks.com/details.asp?invtid=967209-0403-CS&cat=PDA |
| 23:44.00 | solar | you know there are probably lots of them out there that use the miniusb plug |
| 23:44.12 | prpplague | yea |
| 23:44.21 | RobotGuy | Is it possible to have openocd write the flash (jffs2) along with the bootloader and kernel? |
| 23:44.43 | prpplague | yep |
| 23:45.00 | prpplague | just look at the hammer.ocd |
| 23:45.02 | prpplague | script |
| 23:45.06 | prpplague | and make the change |
| 23:45.13 | RobotGuy | Do I just need to use the appropriate address and filename? |
| 23:45.17 | prpplague | yep |
| 23:46.54 | solar | prpplague: a better looking rubber roll up one. http://tinyurl.com/6q7sru (the orange will match the nail-rev-b case holders) |
| 23:47.52 | ds2 | isn't interfacing to something like this easier (just a UART) - http://www.amazon.com/Targus-PA765U-ThumbPad-Keyboard/dp/B00006B90I |
| 23:48.27 | prpplague | ds2 yea they are about the same, most of them have linux drivers already |
| 23:48.50 | prpplague | solar oh that one is cute |
| 23:50.12 | ds2 | prpplague: the USB keyboards would consume a precious resource on the hammer (endpoint + a usb port) |
| 23:51.36 | RobotGuy | You could do like on Nail, but just make all four USB ports available to the outside. |
| 23:51.54 | prpplague | ds2 i'm not doing a production board |
| 23:52.03 | prpplague | ds2 just something to show off at lwe |
| 23:52.28 | ds2 | prpplague: still, even for a demo having an extra USB port is handy |
| 23:52.49 | RobotGuy | Two double stacked type A USB connector sets. |
| 23:53.43 | solar | however i still like making a mini keyboard out of another altoids tin. You have the little altois nativity scene setup |
| 23:54.12 | ds2 | btw, I got some of those keyboards cheap when geeks.com was clearing them out |
| 23:54.15 | solar | hrmm thats whee bluetooth could come in handy |
| 23:54.19 | solar | where |
| 23:54.23 | RobotGuy | Play connect the Altoids tins |
| 23:54.30 | ds2 | where? |
| 23:54.36 | RobotGuy | A modular embedded system |
| 23:55.53 | RobotGuy | solar: I have a serial bluetooth module. |
| 23:57.40 | RobotGuy | beats on his wheelchair controller |
| 23:58.18 | solar | codes already written for that and there seems to be plenty bluetooth gadgets. |
| 23:58.36 | solar | would free up the whole display area of messy wires connected back to all the ports |
| 23:58.47 | ds2 | a BT keyboard would be cool |
| 23:59.13 | solar | mouse as well. You can use more than one BT at a time right? |
| 23:59.18 | ds2 | maybe also have it play OGGs on a A2DP speaker? |
| 23:59.25 | ds2 | yeah, bluez will let you do that |
| 23:59.59 | RobotGuy | ds2: We don't have bluez for Hammer |
