| 03:13.35 | sunrunner | fets will switch if you put your finger accross the gate contact, right? |
| 03:13.46 | sunrunner | (create a circuit between source and gate via finger) |
| 03:21.13 | joe_bleau | What kind of FET? |
| 03:29.53 | sunrunner | some can cant' they? |
| 03:30.16 | sunrunner | nchanel logic level? |
| 03:36.48 | davidc__ | sunrunner: hell - some fets will switch if you blow on them |
| 04:05.24 | sunrunner | :p |
| 04:37.19 | joe_bleau | You'd want to pull the gate towards the *drain* to turn in on (make the drain-source path conduct), in that case (n-channel enhancement fet). Pulling the gate to the source would turn it off. |

| 17:04.49 | joe_bleau | prpplague: working on sunday? Must be rough... |
| 17:06.00 | prpplague | joe_bleau: yea, been working for like 5 weekends in a row |
| 17:06.09 | agaffney | what do you do? |
| 17:06.21 | prpplague | joe_bleau: i'm in the process of remodeling a room at the house to be an office |
| 17:06.31 | prpplague | joe_bleau: so you'll soon see on my online 24x7 |
| 17:06.53 | joe_bleau | Well, I don't know that *I'll* see you more, but I get your point. |
| 17:07.04 | joe_bleau | Only problem with working from home is that you can work from home. |
| 17:08.01 | prpplague | ?? |
| 17:08.21 | joe_bleau | I'm set up to work here at the house. Consequently, no one at work worries about problems over the weekend, |
| 17:08.35 | joe_bleau | 'cause they can call me up, order a firmware fix, and get it delivered while they wait. |
| 17:08.49 | prpplague | ahh |
| 17:08.50 | joe_bleau | And there rings the cell phone! |
| 17:08.57 | prpplague | hehe |
| 17:09.08 | joe_bleau | Wrong number. |
| 17:09.13 | prpplague | btdt |
| 17:09.30 | prpplague | but my main thing is that i'm a late evening worker |
| 17:09.46 | prpplague | my most productive time is from about 11am till around 10pm |
| 17:10.00 | prpplague | can't exactly stay at the office till then |
| 17:10.06 | joe_bleau | You're the only one at your location, though, right? |
| 17:10.11 | prpplague | yea |
| 17:10.47 | prpplague | techincally i could stay, but its not very safe |
| 17:10.55 | joe_bleau | Safe? How's that? |
| 17:10.59 | joe_bleau | Monkey attacks? |
| 17:11.06 | prpplague | hehe |
| 17:11.09 | prpplague | kidnapping |
| 17:11.12 | joe_bleau | Rumrunners? |
| 17:11.20 | joe_bleau | Jeez, are you serious? |
| 17:12.11 | joe_bleau | Can you get a concealed carry permit (assuming you even need a permit)? If nothing else, it might give you some piece of mind. |
| 17:12.52 | prpplague | i'm not a citizen so i can't carry, and even if i was a citizen, its extremely difficult to get a gun |
| 17:13.22 | joe_bleau | Understood. Moving on... |
| 17:13.37 | prpplague | joe_bleau: i have never seen a culture so confused about defending themselves |
| 17:14.10 | prpplague | joe_bleau: almost everyone has bars on the doors and windows, yet they keep passing laws about gun controll and self defense and stuff |
| 17:14.15 | joe_bleau | Sounds like it. But I didn't mean to open the channel up to my gun rants. |
| 17:14.20 | prpplague | joe_bleau: only the criminals have guns |
| 17:14.25 | prpplague | hehe |
| 17:14.48 | prpplague | yea, i try to keep most of the politicin off the channel |
| 17:15.57 | joe_bleau | Know of any IRC channels devoted to the Moto/Freescale Coldfire? I'm still studying the LCF5329 (LCD+CAN+Ethernet+SDRAM) |
| 17:16.36 | prpplague | sorry no, however there are a ton of small channels on freenode |
| 17:17.12 | joe_bleau | I guess I could start one, but I'm looking to leach off other's experience, not become a useful source of info. |
| 17:17.36 | prpplague | hehe, sounds like me |
| 17:18.59 | joe_bleau | Oh, a few weeks ago we discussed some nintendo on a chip toy that I saw in the sunday sales ads, right? |
| 17:19.20 | prpplague | yea |
| 17:19.55 | joe_bleau | I try and spend sunday afternoons doing nothing. Ended up reading a lot on nintendo (never played one), crossed over to the old atari 2600 stuff. |
| 17:20.06 | joe_bleau | Turns out that people are writing homebrew apps for it. |
| 17:20.15 | prpplague | yea |
| 17:20.23 | joe_bleau | *Extremely* limited architecture. |
| 17:20.39 | joe_bleau | So, fair warning: if I start hacking on my old 2600, it's all your fault. |
| 17:20.50 | prpplague | hehe yea |
| 17:21.00 | joe_bleau | It looks like a massive time sink. |
| 17:21.01 | prpplague | they used to sell a homebrew 2600 cart |
| 17:21.06 | prpplague | HA |
| 17:22.56 | joe_bleau | y'all do DST or 'summer time' or something like that down on that island of yours? |
| 17:23.15 | prpplague | joe_bleau: i have a taken an oath on the ARM-ARM, that i won't take on any projects that don't advance my skills in doing embedded systems |
| 17:23.18 | prpplague | joe_bleau: naw |
| 17:23.27 | joe_bleau | lol. |
| 17:23.46 | joe_bleau | But see, it fits with my sunday afternoon plan to do nothing useful. |
| 17:23.53 | prpplague | joe_bleau: hehe yea |
| 17:24.00 | joe_bleau | If it tickles my fancy, no matter how unproductive, I'm ok with it. |
| 17:24.11 | joe_bleau | Kinda like the OpenRPN project. |
| 17:24.29 | joe_bleau | But hey, I'm still exploring options and thinking about thinking about it. Not actually doing anything. |
| 17:24.31 | prpplague | hehe usually i'm that way as well, but i've been working hard to perfect my embedded skills |
| 17:25.04 | joe_bleau | I've started linting all my code. That's my latest new habit. |
| 17:25.19 | joe_bleau | Still working up to more consistent use of Doxygen. |
| 17:25.43 | joe_bleau | Down the road, I'd love to work up a unit test framework for our embedded stuff. |
| 17:25.54 | prpplague | hehe |
| 17:26.04 | prpplague | yea i need to break into writing drivers for 2.6 |
| 17:26.06 | joe_bleau | I'm serious. |
| 17:27.01 | prpplague | sorry its a habbit, doing the "hehe" |
| 17:27.35 | joe_bleau | Hey! Are you making fun of my spelling, or my bad grammer, bubba. ;-) |
| 17:28.17 | prpplague | neither, making fun of your attempt to generate documented code! |
| 17:28.29 | joe_bleau | Oh, yeah, that. |
| 17:28.47 | joe_bleau | gotta eat. bbl |
| 17:29.36 | prpplague | later |
| 17:43.34 | joe_bleau | Oh, and I want to move a lot of duplicated code into libraries. No real reason to have 100 copies of the same files floating around. |
| 17:45.06 | prpplague | hehe yea |
| 17:47.03 | joe_bleau | I count about 400 projects in my source path. I'll bet 30-50% are still in use. |
| 17:47.28 | sunrunner20 | would ya'll be willing to write me a usb to sound input driver for linux? |
| 17:47.39 | sunrunner20 | most recent Uclinux ver |
| 17:48.39 | sunrunner20 | but i only have hardware skills |
| 17:49.06 | joe_bleau | sunrunner20: did you get your fet circuit working? |
| 17:50.14 | sunrunner20 | i just need to know what kind of fet i need |
| 17:51.20 | sunrunner20 | its for somebody else |

| 18:52.17 | joe_bleau | I see Luminary is shipping Cortex-M3 based micros. |
| 18:52.58 | joe_bleau | I'm hoping it'll put some price and performance pressure on the arm7 microcontroller vendors. |
| 18:53.30 | prpplague | hehe, i always thought the price of the arm7 stuff was very reasonable |
| 18:53.47 | prpplague | it was always the dev boards that were expensive imho |
| 18:54.28 | joe_bleau | Olimex will probably spin some cheap boards, but I'm not thrilled with their PWB quality. |
| 18:54.44 | joe_bleau | Hey, the first AVR32 chip has a bunch of spiffy stuff onboard. |
| 18:55.21 | joe_bleau | But as a (very minor) arm shareholder, I'm hoping for a nice round of new Cortex license signups... |
| 18:55.45 | sunrunner20 | hmm |
| 18:56.04 | sunrunner20 | know of any cheap powerfull boards that have multipul USB ports? |

| 18:57.27 | prpplague | sunrunner20: s3c2410 has can have two usb master |
| 18:57.31 | prpplague | sunrunner20: but why? |
| 18:57.43 | prpplague | sunrunner20: why not just add a one chip usb hub? |
