[08:59] <rjharrison> morning all
[08:59] <rjharrison> any news on the channel?
[09:21] <G8TMV> naw, no one has said anything since about 10pm
[09:23] <earthshine> hello
[09:23] <earthshine> is there a laucnh this weekend? If so I can take my radio gear with me (going camping)
[09:24] <G8TMV> earthshine: I think rjharrison is planning one for tomorrow
[09:25] <earthshine> cool, I can take my radio and yagi
[09:27] <G8TMV> earthshine: there is also a 2m rsgb contest on Sunday afternoon if you are interested
[09:27] <GW8RAK> Morning. I'm building a Moxon aerial this afternoon and will be able to compare it with a log periodic.
[09:27] <juxta> earthshine: jcoxon mentioned Rob might be trying alt record I think this weekend :)
[09:29] <earthshine> G8TMV: I don't have a licence (yet) and onyl a 70cm receiver
[09:29] <earthshine> I have an FT-790R - bought purely for the purpose of listening in on teh HAB launches
[09:30] <earthshine> Though I do intend on getting my licence at some time in the future
[09:30] <G8TMV> earthshine: Ah, ok
[09:31] <earthshine> WHich probably won't be till around October at the earliest now as I have just signed a book contract and will be busy writing for teh next 6 months
[09:31] <G8TMV> Book, what sort of book? a techie type one or fiction?
[09:33] <earthshine> Techie - It's a beginners book for the Arduino
[09:34] <G8TMV> Ah, right, what processor do they use?
[09:34] <earthshine> there is a big gap in the market for one - especially as the only beginners book is the absolutely atrocious "Getting started"
[09:34] <earthshine> Atmel Atmega328
[09:34] <G8TMV> <g> thats the "competition" as far as I'm concerned
[09:36] <earthshine> Getting started is out of date, way too short, lacking in information, it's almost useless for a beginner
[09:36] <earthshine> My book has 50 projects ranging from simple flashign LED's right through to using Ethernet modules
[09:36] <earthshine> lots of diagrams
[09:36] <G8TMV> Do you know Brad Smith, he's a collegue here at ARM and also the Debian porter for AVR
[09:36] <earthshine> hands on learning as you go rather than pages of theory
[09:37] <earthshine> No I don't
[09:37] <earthshine> You work at ARM ?
[09:37] <G8TMV> yes, on the reference platforms, I'm a kernel developer
[09:37] <earthshine> I'm slowly moving over to ARM for more complex stuff
[09:37] <earthshine> I like the mbed - you know that?
[09:37] <G8TMV> our mbed is looking good and there will be a psoc based on an M4 soon
[09:38] <earthshine> I think ARM is the next step from peeps that started with Arduinoa nd PIC
[09:38] <G8TMV> yes, I was talking to Chris this week about getting a project going with a local school using an mbed in a balloon
[09:38] <earthshine> I just wish ARM did DIP chips
[09:39] <earthshine> hobbiests need DIP
[09:39] Action: G8TMV nods, too many pins for that really, even on an M4
[09:39] <earthshine> yeah i guess so
[09:39] <G8TMV> that is what mbed is supposed to address
[09:39] <earthshine> true - i like the mbed
[09:39] <earthshine> But.......
[09:40] <earthshine> one of the great things about an ARduino is, you can make a concept, then pop the chip out and put it onto your own custom PCB
[09:40] <earthshine> you can't do that with an mbed without sacrificing the whole board
[09:40] <junderwood> SMT isn't difficult once you've got over the initial fright factor
[09:40] <earthshine> that's why so many people love Arduino's they are ideal for home made PCBs
[09:40] <earthshine> yeah i've seen people solder SMT and it doesn't look to difficult at all
[09:41] <G8TMV> well the mbeds are effectively a big dip chip, you could easily fit a socket to whatever you want to put it in and move it from project to project
[09:41] <earthshine> i suppose
[09:41] <earthshine> but it would be epensive for a permanent device
[09:42] <earthshine> Let's hope Apple don't get their grubby mits on ARM
[09:42] <G8TMV> yes, but then it wasn't designed to be a permanent device, it was designed for school-type projects and prototypes

[14:26] <G8TMV> futurity: he said he was launching tomorrow at 9 utc
[14:26] <futurity> cool so its still on
[14:26] <jonsowman> yup, weather looking good
[14:26] <futurity> i may still be able to help out, although oldest son was ill last night so still a bit touvh and go
[14:26] <G8TMV> 11:56 < rjharrison> Hi guys a quick up date Icarus III will be making its debut launch at 0900 UTC tomorrow
[14:27] <futurity> i think he's looking to go for the altitude record

[16:41] Jasperw (~jasperw@93.89.81.29) joined #highaltitude.
[16:41] <Randomskk> the chinese ones work quite well tb
[16:41] <Randomskk> pcb-train in the UK is probably your best bet for small qty
[16:41] <fsphil> very small qty in my case
[16:41] <fsphil> probably only 10 or so
[16:41] <Randomskk> but seeed studio, gold phoenix, pcbcart, batchpcb are all good
[16:41] <Randomskk> for qty10 I'd say seeedstudio is your best bet
[16:42] <fsphil> thanks, I didn't see them when googling. will have a look now

[17:20] <fsphil> sweet -- when are you hoping to launch?
[17:24] <stilldavid> fsphil, well, it's open ended now.
[17:24] <stilldavid> depending on what form I need :P
[17:24] <fsphil> haha
[17:25] <stilldavid> a month ago I was planning on this Sunday (2 days!) but I might have to postpone
[17:25] <stilldavid> the last week I've talked to probably a half dozen different people in different offices.
[17:25] <fsphil> all in the FAA?
[17:25] <stilldavid> now I'm waiting to hear back from the Ballooning director at the FAA regional headquarters
[17:26] <stilldavid> FAA and the local airport (DEN - largest airport in the US)
[17:30] <fsphil> how is the airport taking it? supportive?
[17:32] <stilldavid> they are basically saying stay the heck away from them at all costs, which I plan on doing
[17:32] <stilldavid> I'm talking to a guy from EOSS.org, which is great as well. They're Colorado based as well
[17:33] <fsphil> yes - getting close to them would be 'very bad'
[17:33] <stilldavid> http://www.eoss.org/flight/predict_map_over_dia_class_b.htm
[17:33] <stilldavid> the second photo is what did it for me
[17:33] <fsphil> holy crap
[17:34] <stilldavid> so yeah, if I can get away without filling out the waiver (which takes ~45 days to process...) I'll launch from up north somewhere as in the first photo
[17:38] <G8TMV> Hey! launching from Denver is cheating! you get a mile start fro free! ;)
[18:01] <stilldavid> G8TMV, not looking to set records (yet) but I was actually curious about that...
[18:01] <stilldavid> do I follow standard filling procedures and all?
[18:03] <G8TMV> don't know
[18:03] <stilldavid> I'm just going to play it by ear then. I kind of expect to learn a lot on my first go-round

[19:15] Action: Randomskk is watching the stream :D
[19:15] <stilldavid> http://www.nasa.gov/multimedia/nasatv/index.html
[19:15] <stilldavid> or the ustream one
[19:35] <fsphil> ah, the last atlantis launch
[19:41] <fsphil> that is an amazing machine
[19:45] <Randomskk> it really is
[19:48] <SpeedEvil> Amazingly stupid in many ways.
[19:48] <SpeedEvil> The design was so constrained by stupid requirements.
[19:49] <SpeedEvil> For example - one of the primary drivers for the wings was being able to launch a replacement spysat in polar orbit, and have enough crossrange to land back on the takeoff point.
[19:49] <SpeedEvil> which...
[19:49] <Randomskk> oh, sure, but despite all that it's nevertheless an incredible thing to watch

[22:45] <jcoxon> hehe no email yet to the list from rjharrison
[22:46] <Randomskk> hmm
[22:46] <Randomskk> launch is at 10AM right?
[22:46] <jcoxon> meant to be
[22:46] <Randomskk> less than twelve hours... :o
[22:46] <jcoxon> i reminded him to email the list - as he'll need as many listeners as possible to make a claim at the record
[22:47] <Randomskk> surely it'd be a fairly easy record to beat if you just bought an expensive large balloon and put on a very lightweight payload?
[22:47] <jcoxon> Randomskk, sure if you were the only one to have a 3kg balloon
[22:48] <Randomskk> :P true, so what's the rest of the subtly?
[22:48] <jcoxon> unfortunately thats been done so now its all about timing, ridiculously slow ascent rate so as little He as possible
[22:48] <jcoxon> perfect condition balloon
[22:48] <jcoxon> careful fulling
[22:49] <Randomskk> right
[22:49] <jcoxon> the payload tomorrow isn't that light
[22:49] <Randomskk> or just have your module report altitude*1.1 or such :P

[22:49] <Randomskk> hmm

[23:04] <stilldavid> I wonder if I should just launch on Sunday. I haven't heard back from the regional balloon person at the FAA
[23:04] <stilldavid> I'm 99% sure I'm exempt and just need to call the ATC before launch, but I don't know for _sure_...
[23:05] <jcoxon> what to eoss say?
[23:05] <jcoxon> stilldavid, my advice is never to rush into a launch
[23:05] <stilldavid> jcoxon, good idea, but I've just had this date set for a while and only just been able to talk to the right people about it
[23:05] <jcoxon> be patient young skywalker
[23:05] <stilldavid> EOSS has a blanket waiver that lets them do pretty much whatever they want whenever they want in any conditions
[23:06] <jcoxon> hehe well they've done this for a while
[23:06] <stilldavid> exactly, and the guy I talked to couldn't even remember operating outside of the waiver it's been so long
[23:07] <jcoxon> so yeah recommend waiting
