[02:50] Anyone able to tell if this bird is a Peregrine Falcon? https://plus.google.com/photos/105095769731159704550/albums/5627748242523559489?authkey=COCT7YWa-NuoHw [02:51] Title: [Nature - Google+] [03:04] MarkDude: No, not a peregrine. I don't have my bird books here, but probably a red-shouldered hawk. [03:04] Nice pix of it! I've always had trouble getting good pix of them. [03:05] Best I've gotten (not nearly as good): http://shallowsky.com/Birds/showbird.php?pat=Raptors/red_shouldered_hawk [03:05] Title: [red shouldered hawk] [03:09] Aha [03:09] Ty akk [03:09] Makes sense. [03:10] The bird does not sound as impressive as I thought it would [03:10] Makes sortof a chirping noise [03:10] Yeah, hawks make surprisingly un-fierce noises. :) [03:11] Bluejays sound tougher [03:11] 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] (I suspect she meant red-tailed) [03:11] and they searched around and finally found it, and it was this wimpy "eep, eep" sound [03:11] and I think they opted to put in some dramatic music instead :) [03:12] Stellar's Jays actually like to imitate red-shouldered hawks. [03:12] Which probably makes them sound very fierce to whatever bird-eating predator they're trying to fool. [03:13] 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." [03:14] There is a mated pair of jays that come to my feeder, unlike the others, these two are quiet [03:14] Sorta nod to me to feed them [03:14] No need to alert other birds [03:14] Nice! [03:14] I like jays, they're so smart. [03:14] Yep [03:15] I like crows also- but more at a distance [03:15] hella smart [03:15] Yep! [03:15] I love watching crows and ravens practice flying. [03:15] but there is a reason they are called a murder of crows [03:15] They can chase of raptors in groups of 10+ here [03:16] And then jays and mockingbirds and blackbirds chase the crows. [03:16] Yep [03:16] And smaller hawks chase bigger hawks. [03:16] Circle of life [03:17] Aerial fights are insane to watch [03:17] What's most fun, though, is seeing mockingbirds chase off cats and dogs. Those little guys (of both genders) are fearless. [03:17] The most aawesome, are hummingbirds [03:17] Yeah, them too. [03:17] Jays will chase cats from tree to tree [03:17] I still boggle that there's a whole working brain and heart and everything else inside that tiny body. [03:18] Squirrels just complain a bit, jays will dive bomb [03:19] brb [03:23] Pi event on Sat, I know you wont are not free for a few months akk [03:24] Yeah, definitely not this sat. But maybe next month! [03:24] But, I wanted to see if we could get some input from you on goals part [03:24] We are gonna do a G+ hangout irc meeting Sat 3-4pm- for folks not able to attend [03:25] Chris is having us get some accessories [03:27] * MarkDude wants to see about starting with the flag waving wiring [03:28] 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] http://raspi.tv/2013/how-to-make-your-own-raspberry-pi-flag-waving-demo [03:28] Title: [How to make your own Raspberry Pi flag-waving demo ยป RasPi.TV] [03:28] Sure, if not we have a wiki page [03:28] I like the flag one- since not much is needed to make it [03:28] Using existing connectors first [03:29] Then I can solder up a storm [03:30] Wow, the RPi can drive a servo directly? I'm surprised. [03:31] Yep [03:31] The way it does it is rather nice [03:31] Needs to be tuned to servo [03:32] I would have worried about pulling too much current or getting back EMF or something. [03:32] Maybe servos don't have a risk of back EMF. [03:34] The pin they use is isolated [03:34] * MarkDude is assuming [03:34] If it were variable - that might be an issue, [03:34] it's one speed only [03:37] I didn't think anything was isolated in the RPi. [03:41] Well you remember how I qualify my technical opinions; [03:41] Think of me as a less charming Jono [03:42] * MarkDude knows Community 1st, the rest comes down the list [03:42] My real tech is actual electronics and soldering type stuff, as well as having a Ham license N6TBD [03:43] So the Pi has been good for me to learn, especially with ARM having a great future as near as I can tell [03:44] Yep, certainly looks like it has. [03:44] Intel's dropped the ball on low-power chips. [03:45] * 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] I was warned about that being an issue if I tried to drive motors or speakers directly from an arduino. [03:46] And AFAIK the RPi is much more delicate than an arduino -- certainly it's far more sensitive to overvoltage. [03:47] yeah, people have toasted their pis by even using the wrong charging cable [03:47] Ok, though servos are almost operated by relays [03:48] the voltage to trigger is not always related to operating device [03:48] Really? I didn't know that. [03:48] I'd seen warnings against using big servos on arduinos, but that a small one was probably okay. [03:49] 5V from battery only goes to the servo). [03:49] In this project [03:49] its using it as a pass thru in effect [03:51] The ground is protected enough- [03:52] From what I have read tho- what you are saying is true [03:52] I think some of the switching can be done with simple switching relays. for some pretty neat more complex projects [03:54] * MarkDude was thinking of emailing for Pi gatherings to DVLUG list, and one other Local ML [03:54] RM be damed [03:54] 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) [03:55] * MarkDude kids of course. [03:55] and ended up having better success with transistors, once someone showed me how to use them. [03:55] Well yep [03:55] MarkDude: As long as you say the RPis should run debian and not ubuntu, you might get away with it. [03:56] Just don't say the u-word on too many of those LUG lists. :) [03:56] Its almost as if we could gather enough transistors - we could make a computer [03:56] :D [03:56] Whoa, you think? :) [03:56] Well, Debian of some sort, Fedora for server - and sumthin like Puppy or whatever develops as stable [03:57] * MarkDude would like SELinux working for server [03:57] Geek points [03:58] What other list? Berkeley lug? [03:58] Bug Jack? [03:58] :D [03:58] * MarkDude should see if paulproteus is interested in such things, or just the next Geeknic [03:59] Relays make a very satisfying geeky awesome click - its neato [04:00] True. Also, I love those great big relays with the transparent covers where you can see the levers moving. [04:00] 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 [04:01] Add blinky lights for NO reason [04:01] You can get them at Ham swap meets [04:01] It's even better when there is a reason. Like on connection machines, where the lights indicated which processor was active. [04:01] blinky lights FTW [04:02] 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] There are other parts of Radio Shack? :) [04:03] 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] The manager knows my routine, wander first- looking for bargains, then the drawers [04:03] Its an addiction [04:04] * MarkDude wants to see what we can do with LCD fun also [04:04] LCDs are fun but a lot harder to wire up. [04:05] * MarkDude actuall started wiring ICs [04:05] like chips in boards [04:05] Another cool but usually pointless thing, then: wire-wrap. [04:05] if you were good, you just needed heatsinks [04:06] OMG [04:06] * MarkDude is adding that ot BAMF/Pi todo list [04:06] in colors [04:07] Its actually useful for some things- like marking the deadly wires for solar panels- or other fun [04:07] Mostly it looks cool [04:08] * MarkDude needs to post pics if his Pi and post it later [05:12] mm === MediaDoneRight is now known as mikestewart
