| MarkDude | Anyone able to tell if this bird is a Peregrine Falcon? https://plus.google.com/photos/105095769731159704550/albums/5627748242523559489?authkey=COCT7YWa-NuoHw | 02:50 |

| akk | MarkDude: No, not a peregrine. I don't have my bird books here, but probably a red-shouldered hawk. | 03:04 |
| akk | Nice pix of it! I've always had trouble getting good pix of them. | 03:04 |
| akk | Best I've gotten (not nearly as good): http://shallowsky.com/Birds/showbird.php?pat=Raptors/red_shouldered_hawk | 03:05 |
| darthrobot` | Title: [red shouldered hawk] | 03:05 |
| MarkDude | Aha | 03:09 |
| MarkDude | Ty akk | 03:09 |
| MarkDude | Makes sense. | 03:09 |
| MarkDude | The bird does not sound as impressive as I thought it would | 03:10 |
| MarkDude | Makes sortof a chirping noise | 03:10 |
| akk | Yeah, hawks make surprisingly un-fierce noises. :) | 03:10 |
| MarkDude | Bluejays sound tougher | 03:11 |
| akk | My mom used to work on animal documentaries, and she told me a story about when they needed to find a clip of the cry of the red hawk | 03:11 |
| akk | (I suspect she meant red-tailed) | 03:11 |
| akk | and they searched around and finally found it, and it was this wimpy "eep, eep" sound | 03:11 |
| akk | and I think they opted to put in some dramatic music instead :) | 03:11 |
| akk | Stellar's Jays actually like to imitate red-shouldered hawks. | 03:12 |
| akk | Which probably makes them sound very fierce to whatever bird-eating predator they're trying to fool. | 03:12 |
| akk | They used to fool me all the time, "How could a great big hawk be way up there at the top of that tree? Oh, it's just a jay again." | 03:13 |
| MarkDude | There is a mated pair of jays that come to my feeder, unlike the others, these two are quiet | 03:14 |
| MarkDude | Sorta nod to me to feed them | 03:14 |
| MarkDude | No need to alert other birds | 03:14 |
| akk | Nice! | 03:14 |
| akk | I like jays, they're so smart. | 03:14 |
| MarkDude | Yep | 03:14 |
| MarkDude | I like crows also- but more at a distance | 03:15 |
| MarkDude | hella smart | 03:15 |
| akk | Yep! | 03:15 |
| akk | I love watching crows and ravens practice flying. | 03:15 |
| MarkDude | but there is a reason they are called a murder of crows | 03:15 |
| MarkDude | They can chase of raptors in groups of 10+ here | 03:15 |
| akk | And then jays and mockingbirds and blackbirds chase the crows. | 03:16 |
| MarkDude | Yep | 03:16 |
| akk | And smaller hawks chase bigger hawks. | 03:16 |
| MarkDude | Circle of life | 03:16 |
| MarkDude | Aerial fights are insane to watch | 03:17 |
| akk | What's most fun, though, is seeing mockingbirds chase off cats and dogs. Those little guys (of both genders) are fearless. | 03:17 |
| MarkDude | The most aawesome, are hummingbirds | 03:17 |
| akk | Yeah, them too. | 03:17 |
| MarkDude | Jays will chase cats from tree to tree | 03:17 |
| akk | I still boggle that there's a whole working brain and heart and everything else inside that tiny body. | 03:17 |
| MarkDude | Squirrels just complain a bit, jays will dive bomb | 03:18 |
| MarkDude | brb | 03:19 |
| MarkDude | Pi event on Sat, I know you wont are not free for a few months akk | 03:23 |
| akk | Yeah, definitely not this sat. But maybe next month! | 03:24 |
| MarkDude | But, I wanted to see if we could get some input from you on goals part | 03:24 |
| MarkDude | We are gonna do a G+ hangout irc meeting Sat 3-4pm- for folks not able to attend | 03:24 |
| MarkDude | Chris is having us get some accessories | 03:25 |
| * MarkDude wants to see about starting with the flag waving wiring | 03:27 | |
| akk | No guarantees about where I'll be 3-4 on sat, but send me the link and if I'm near my computer, I'll try. | 03:28 |
| MarkDude | http://raspi.tv/2013/how-to-make-your-own-raspberry-pi-flag-waving-demo | 03:28 |
| darthrobot` | Title: [How to make your own Raspberry Pi flag-waving demo ยป RasPi.TV] | 03:28 |
| MarkDude | Sure, if not we have a wiki page | 03:28 |
| MarkDude | I like the flag one- since not much is needed to make it | 03:28 |
| MarkDude | Using existing connectors first | 03:28 |
| MarkDude | Then I can solder up a storm | 03:29 |
| akk | Wow, the RPi can drive a servo directly? I'm surprised. | 03:30 |
| MarkDude | Yep | 03:31 |
| MarkDude | The way it does it is rather nice | 03:31 |
| MarkDude | Needs to be tuned to servo | 03:31 |
| akk | I would have worried about pulling too much current or getting back EMF or something. | 03:32 |
| akk | Maybe servos don't have a risk of back EMF. | 03:32 |
| MarkDude | The pin they use is isolated | 03:34 |
| * MarkDude is assuming | 03:34 | |
| MarkDude | If it were variable - that might be an issue, | 03:34 |
| MarkDude | it's one speed only | 03:34 |
| akk | I didn't think anything was isolated in the RPi. | 03:37 |
| MarkDude | Well you remember how I qualify my technical opinions; | 03:41 |
| MarkDude | Think of me as a less charming Jono | 03:41 |
| * MarkDude knows Community 1st, the rest comes down the list | 03:42 | |
| MarkDude | My real tech is actual electronics and soldering type stuff, as well as having a Ham license N6TBD | 03:42 |
| MarkDude | So the Pi has been good for me to learn, especially with ARM having a great future as near as I can tell | 03:43 |
| akk | Yep, certainly looks like it has. | 03:44 |
| akk | Intel's dropped the ball on low-power chips. | 03:44 |
| * MarkDude had not been thinking of EMF on that level, more so looking at it like straight electricity, and it would dissipate at such a quick rate vs distancce | 03:45 | |
| akk | I was warned about that being an issue if I tried to drive motors or speakers directly from an arduino. | 03:45 |
| akk | And AFAIK the RPi is much more delicate than an arduino -- certainly it's far more sensitive to overvoltage. | 03:46 |
| pleia2 | yeah, people have toasted their pis by even using the wrong charging cable | 03:47 |
| MarkDude | Ok, though servos are almost operated by relays | 03:47 |
| MarkDude | the voltage to trigger is not always related to operating device | 03:48 |
| akk | Really? I didn't know that. | 03:48 |
| akk | I'd seen warnings against using big servos on arduinos, but that a small one was probably okay. | 03:48 |
| MarkDude | 5V from battery only goes to the servo). | 03:49 |
| MarkDude | In this project | 03:49 |
| MarkDude | its using it as a pass thru in effect | 03:49 |
| MarkDude | The ground is protected enough- | 03:51 |
| MarkDude | From what I have read tho- what you are saying is true | 03:52 |
| MarkDude | I think some of the switching can be done with simple switching relays. for some pretty neat more complex projects | 03:52 |
| * MarkDude was thinking of emailing for Pi gatherings to DVLUG list, and one other Local ML | 03:54 | |
| MarkDude | RM be damed | 03:54 |
| akk | I tried to use relays for my shark project, and had a lot of trouble (partly it was just finding the right kind of relay) | 03:54 |
| * MarkDude kids of course. | 03:55 | |
| akk | and ended up having better success with transistors, once someone showed me how to use them. | 03:55 |
| MarkDude | Well yep | 03:55 |
| akk | MarkDude: As long as you say the RPis should run debian and not ubuntu, you might get away with it. | 03:55 |
| akk | Just don't say the u-word on too many of those LUG lists. :) | 03:56 |
| MarkDude | Its almost as if we could gather enough transistors - we could make a computer | 03:56 |
| MarkDude | :D | 03:56 |
| akk | Whoa, you think? :) | 03:56 |
| MarkDude | Well, Debian of some sort, Fedora for server - and sumthin like Puppy or whatever develops as stable | 03:56 |
| * MarkDude would like SELinux working for server | 03:57 | |
| MarkDude | Geek points | 03:57 |
| MarkDude | What other list? Berkeley lug? | 03:58 |
| MarkDude | Bug Jack? | 03:58 |
| MarkDude | :D | 03:58 |
| * MarkDude should see if paulproteus is interested in such things, or just the next Geeknic | 03:58 | |
| MarkDude | Relays make a very satisfying geeky awesome click - its neato | 03:59 |
| akk | True. Also, I love those great big relays with the transparent covers where you can see the levers moving. | 04:00 |
| akk | Dunno if they make those any more, but I had one when I was a kid. | 04:00 |
| * MarkDude is thinking of doing this like Univac | 04:00 | |
| MarkDude | Add blinky lights for NO reason | 04:01 |
| MarkDude | You can get them at Ham swap meets | 04:01 |
| akk | It's even better when there is a reason. Like on connection machines, where the lights indicated which processor was active. | 04:01 |
| akk | blinky lights FTW | 04:01 |
| MarkDude | Yep | 04:02 |
| * MarkDude has stack of them waiting to be used in projects | 04:02 | |
| * MarkDude likes the center part of Radio Shack. The DRAWERS | 04:02 | |
| akk | There are other parts of Radio Shack? :) | 04:02 |
| akk | Though I usually get stuff like that from Halted or Anchor. I only go to RS if it's Sunday and everyone else is closed and I can't wait. | 04:03 |
| MarkDude | The manager knows my routine, wander first- looking for bargains, then the drawers | 04:03 |
| MarkDude | Its an addiction | 04:03 |
| * MarkDude wants to see what we can do with LCD fun also | 04:04 | |
| akk | LCDs are fun but a lot harder to wire up. | 04:04 |
| * MarkDude actuall started wiring ICs | 04:05 | |
| MarkDude | like chips in boards | 04:05 |
| akk | Another cool but usually pointless thing, then: wire-wrap. | 04:05 |
| MarkDude | if you were good, you just needed heatsinks | 04:05 |
| MarkDude | OMG | 04:06 |
| * MarkDude is adding that ot BAMF/Pi todo list | 04:06 | |
| MarkDude | in colors | 04:06 |
| MarkDude | Its actually useful for some things- like marking the deadly wires for solar panels- or other fun | 04:07 |
| MarkDude | Mostly it looks cool | 04:07 |
| * MarkDude needs to post pics if his Pi and post it later | 04:08 | |
