[04:22] <heathkid> how much helium does it take for a Kaymont 1500?
[04:22] <heathkid> yes, I know... stupid question time...
[04:22] <heathkid> going for fast ascent
[04:22] <heathkid> at Dayton
[04:23] <heathkid> don't want to drive across the country to recover the payload! :)
[04:23] <heathkid> <4 lb. payload
[04:23] <heathkid> probably closer to maybe 2 lbs...
[04:24] <heathkid> our payload is *tiny*
[04:24] <nigelvh> Not exactly "tiny" by current standards.
[04:25] <heathkid> well... could probably do a pico
[04:25] <heathkid> and "tiny" it is... nothing else like it for a tracker
[04:26] <heathkid> well... APRS anyway
[04:27] <heathkid> I need to do a test flight before Dayton
[04:27] <nigelvh> So why does it weigh 2 pounds?
[04:27] <heathkid> it may only weigh a few ounces...
[04:27] <heathkid> just worst case...
[04:27] <nigelvh> Any photos?
[04:27] <heathkid> I just don't want to drag a huge tank to Dayton
[04:27] <heathkid> nope
[04:28] <nigelvh> Unfortunate. Myself and KT5TK have each been working on small APRS transmitters as well.
[04:28] <heathkid> just wondering how much He it takes to fill a 1500 to 6' diameter....
[04:28] <nigelvh> I haven't flown mine yet, but it seems to work well here on the ground. KT5TK has flown his.
[04:29] <nigelvh> As for the balloon, I have no idea.
[04:29] <heathkid> bet ours is smaller and more capable! LOL!!! :P
[04:29] <heathkid> just kidding.... let's work together...
[04:29] <nigelvh> Thems be fightin' words.
[04:29] <nigelvh> :P
[04:30] <heathkid> it's not about who's the best... it's about getting ot near space
[04:30] <nigelvh> Here's a photo of my current revision. http://digitalnigel.com/wordpress/wp-content/uploads/2012/12/20121220-142806.jpg
[04:31] <heathkid> I don't have broadband... could you take a larger photo?
[04:32] <heathkid> ;)
[04:32] <nigelvh> Sorry. These days I don't really bother to downsize photos.
[04:32] <heathkid> ...still downloading...
[04:33] <heathkid> oh... there it is!
[04:33] <heathkid> is that the programmer?
[04:33] <heathkid> oh
[04:33] <heathkid> sorry
[04:34] <heathkid> going to be at Dayton?
[04:34] <heathkid> the K7 kinda gives it away...
[04:34] <nigelvh> Unfortunately no, I'm up in washington, so Dayton is a ways away.
[04:34] <heathkid> ah
[04:35] <heathkid> what are you doing with a K7 then?
[04:35] <heathkid> or not yours?
[04:35] <nigelvh> washington is 7
[04:35] <heathkid> really?
[04:35] <nigelvh> Yep
[04:35] <heathkid> huh
[04:36] <heathkid> never kept up on it really...
[04:36] <heathkid> kept my novice callsign since 1982 or so...
[04:36] <nigelvh> But you're also right that it's a vanity call with my initials. But I did keep the right region number.
[04:36] <heathkid> even though I'm a General now
[04:36] <heathkid> going for my Extra
[04:37] <nigelvh> Extra's a good test. I felt like the general was the technician of HF, extra makes you actually know stuff.
[04:37] Action: heathkid is KA8MAV
[04:37] <heathkid> have been since I was 12
[04:38] <nigelvh> I think I got my tech at 16 (I'm 24 now) so not all THAT long.
[04:38] <heathkid> get my extra... will still keep my original callsign...
[04:38] <heathkid> it's who I am
[04:39] <heathkid> dang... I had my tech + for about 15 minutes...
[04:39] <heathkid> then passed my general
[04:39] <heathkid> should have gone for extra... but wasn't ready
[04:39] <nigelvh> I had my tech for a few years. I didn't have a radio so no reason to test up. Then I got a rig and got general, then a year later I got extra.
[04:40] <heathkid> went from Novice to General
[04:40] Action: heathkid is studying...
[04:40] <heathkid> sort of...
[04:41] <nigelvh> So, what's your APRS transmitter setup?
[04:41] <heathkid> not much an Extra can do I can't...
[04:41] <heathkid> it's a GPS receiver with a 2m TXC
[04:41] <heathkid> TX
[04:41] <heathkid> :)
[04:42] <nigelvh> Informative.
[04:42] <heathkid> buy one at Dayton and find out! lol
[04:42] <heathkid> special edition and all...
[04:42] <nigelvh> Haha
[04:42] <heathkid> :)
[04:43] <heathkid> although.... I need hep
[04:43] <heathkid> help
[04:43] <heathkid> never done a launch before
[04:43] <heathkid> going to test a new version of the board
[04:43] <heathkid> before Dayton
[04:43] <nigelvh> Tests are good.
[04:43] <heathkid> yep
[04:44] <nigelvh> Do you NEED at 1500gm balloon?
[04:45] <heathkid> probably not
[04:45] <heathkid> a pico would be more than enough
[04:45] <nigelvh> That would be a lot simpler.
[04:45] <heathkid> but I've got a 1500 begging to be launched!
[04:45] <nigelvh> You'll definitely get higher with a 1500 than a pico
[04:46] <heathkid> oh, and a couple of paragliders (yes I know I'll tangle them taking them out of the box let alone trying to deploy them!!!)
[04:46] <heathkid> like I said... FAST ascent (100k ft.) to burst....
[04:46] <heathkid> still in Ohio
[04:47] <heathkid> or higher... (cutdown hasn't been tested yet)
[04:48] <heathkid> that's why I'm thinking fast ascent...
[04:48] <heathkid> no float
[04:48] <nigelvh> Yeah
[04:49] <heathkid> I'll float later... :)
[04:49] <heathkid> right now I just want to get it UP and get some data/pics
[04:50] <heathkid> and test the APRS
[04:50] <heathkid> ...and maybe RTTY/CW as well at the same time...
[04:50] <nigelvh> I've flown APRS previously (not with this board) and it has worked well for me.
[04:52] <nigelvh> I've also done RTTY in the past. I moved to APRS to gain more listeners.

[07:52] <miloslj> thanks
[07:52] <UpuWork> and read other peoples blogs on what they've done to get ideas

[07:56] <miloslj> thanks
[07:57] <jcoxon> how has icarus cropped up on spacenear.us
[08:00] <x-f> somebody has tested dl-fldigi with the icarus.wav recording from wiki :)
[08:00] <x-f> no idea about the receivers list however
[08:00] <number10> cant be that as several receivers
[08:02] <jcoxon> or has it remembered lots of people have tested it
[08:02] <jcoxon> just a glitch in the system
[08:02] <jcoxon> usually we have realtime data so it doesn't matter

[14:43] <DanielRichman> the bulk of the time for the hourly predictor when running it on a home connection is (I believe) downloading wind data

[14:43] <fsphil> I suspect it'll spend most of its time doing disk IO

[15:47] <fsphil> yes
[15:48] <x-f> right
[15:50] <Hix> how much effect would removing ntx2 from board have on rf? I ballsed up yhe vltage divider :/
[15:53] <eroomde> and yhe tyng
[15:53] <eroomde> hardly any effect Hix
[15:54] <eroomde> just attach an sma directly to the rf otput of the ntx2 and job's a goodun
[15:54] <Hix> ok, excuse worse than normal typing, curently in foetal position with lurgy
[15:54] <eroomde> put a molex connector in the gap where the NTX2 inputs were
[15:54] <eroomde> and just make a custom connecor
[15:55] <Hix> cool. means it can be better insulated too :)
[15:55] <eroomde> might be advantageous to put a small ceramic and decent electoltyic across the power pins at the ntx2
[15:55] <Hix> ok
[15:55] <eroomde> to mitigate against drops and radiation in the power lines to the ntx2
[15:56] <eroomde> for added sex, put the ntx2 in a tiny case with an sma at one end and a lemo at the other
[15:56] <Hix> lemo?
[15:56] <eroomde> lemo = connector machines out of solid awesome
[15:56] <eroomde> haha I'm kidding of course, it's actually machined out of solid money
[15:57] <Randomskk> they do put a veneer of awesome on top of the money though
[15:57] <Randomskk> work borrowed a GPS recorder/replayer a while back
[15:57] <Randomskk> all lemo
[15:57] <Randomskk> I spent a while just plugging things in and out of it

[19:55] <Willdude123> x-f, read books on building robots or start reading books on astronomy, girls and bands?
[19:56] <Willdude123> On the note of robots, I'd quite like to get an irobot create.
[19:56] <lz1dev> why boats?
[19:56] <lz1dev> i want a floating island
[19:56] <fsphil> I built my first robot recently, they're good fun
[19:58] <lz1dev> robots are great, I need to build one to drag me out of bed in the morning
[19:58] <Willdude123> How do I get started? I've got an uno but are there many robots you can make from them?
[19:59] <lz1dev> there are some robot starter kits
[19:59] <chrisstubbs> Willdude123, i wrote this a while ago with the idea of it being "easy to make" http://www.instructables.com/id/USB-Robot/
[20:00] <chrisstubbs> the k8055 is kinda rubbish though, but wiper motors work well :)
[20:02] <Willdude123> A usb interface board is just a microcontroller, right?
[20:03] <chrisstubbs> yeah pretty much. Arduino and a radio link would be nice :()
[20:03] <chrisstubbs> :)
[20:03] <chrisstubbs> i attempted it but those wiper motors kick out a LOT of interference
[20:03] <fsphil> I used an rfm22b
[20:03] <chrisstubbs> especially if you PWM drive them
[20:04] <chrisstubbs> fsphil, with wiper motors?
[20:04] <fsphil> nah just little standard DC motors
[20:04] <fsphil> my robot wasn't very big
[20:05] <chrisstubbs> Ah fair enough :)
[20:05] <Willdude123> I want to get an irobot create but they aren't sold in the UK.
[20:05] <fsphil> I'm tempted to remake it with a model A RPi
[20:05] <fsphil> control it over a web interface, with a usb camera
[20:06] <fsphil> or the Pi camera when it's out
[20:07] <chrisstubbs> fsphil, if you could get the lag down that would be cool. set up a website like http://www.teletoyland.com/ to control it
[20:07] <fsphil> exactly yea
[20:07] <chrisstubbs> i made a web interface for the USB robot that pulled up the camera in one iframe and could be controlled with javascript HTML buttons in another iframe. It was terrible :P
[20:08] <fsphil> that would have made sense at the time though
[20:08] <fsphil> these days I'd just use javascript
[20:09] <chrisstubbs> it did, and it worked. However when you pressed a button it opened a PHP script in yet another iframe, which opened a sockets connection to a VB.net program on the laptop
[20:09] <fsphil> have a charging pad that people could drive over
[20:09] <fsphil> basically leave a couple of them driving around a maze in the spare room or something :)
[20:10] <fsphil> with a note not to run over my dog should it appear
[20:10] <chrisstubbs> do it with quadrocopters :P
[20:10] <fsphil> they'd be amazing for about 5 seconds
[20:10] <fsphil> although they can be programmed with limits
[20:11] <fsphil> indoors it should be pretty safe
[20:11] <chrisstubbs> there was a team that did a multi-quadrocopter thing that could stack up paper bricks. that was amazing
[20:12] <fsphil> did you see the video of the quads throwing and balancing poles?
[20:12] <chrisstubbs> ermm i dont think so!
[20:12] <chrisstubbs> saw a Pi one that could do backflips that was pretty nice

[20:38] <Lunar_Lander> oh
[20:39] daveake (Dave@daveake.plus.com) left #highaltitude ("Leaving").
[20:45] <Willdude123> You?
[20:46] <ali_> hi all, on an arduino, to monitor battery (supply voltage), is it ok to connect an analogue input to the supply of the board? or will that input sink current? or is the supply pin going to show a modified voltage, e.g. regulated?
[20:46] <Willdude123> I'm afraid the last two of x-f's ideas are impossible.
[20:46] <chrisstubbs> if you are using a regulator it will show the regulated voltage
[20:46] <ali_> arduino uno r3
[20:46] <chrisstubbs> have you looked at voltage dividers?
[20:47] <ali_> i figured it was the lazyiest thing to do, but if it is wrong, then i would do it properly :-)
[20:47] <chrisstubbs> you can use the analog pin if the voltage your are measuing is less than the voltage of the board
[20:48] <chrisstubbs> eg max 5v
[20:48] <ali_> so, a divider on the battery pack would probably be the right answer
[20:48] <chrisstubbs> yeah then you scale the input to match the ratio of the voltage divider
[20:48] <fsphil> I think I used a 10:1 divider last time
[20:49] <ali_> and i wont have to worry about current
[20:49] <ali_> i can just use a high impedence devider
[20:49] <chrisstubbs> if you use high value resistors it should be very low current
[20:49] <ali_> so, 1M + 10M ?
[20:50] <chrisstubbs> that would work. i think i used a few K. but then again nothing i build ever works :P
[20:50] <eroomde> hold one a sec
[20:50] <ali_> :-)
[20:50] <mattbrejza> you cant use 10M as youll never charge the sample and hold cap
[20:50] Habjoe (~Habjoe@host81-157-58-35.range81-157.btcentralplus.com) left irc: Ping timeout: 276 seconds
[20:50] <eroomde> the way analog to digital converters work (often) is that they have a capacitor on the input
[20:50] <mattbrejza> i think you need in the 10sKohm range and slowest conversion
[20:50] <eroomde> what mattbrejza said
[20:51] <fsphil> I believe I used 100k and 10k
[20:51] <eroomde> so basically the capacitor gets filled to the same level as the input voltage, then that cap is what gets measured by the adc
[20:51] <ali_> so, you mean i need more current to the AD?
[20:51] <eroomde> if you have a massively high resistance voltage divider, you'll get hardly any current through into that capacitor, so it will take forever to charge
[20:51] <eroomde> ali_: yes exactly
[20:51] <ali_> ok, got it
[20:51] <eroomde> there is a way round this though, if you need, although you don;t for this application
[20:51] <ali_> 100k + 10k then
[20:52] <eroomde> but you can set up an operational amplifier (op amp, 8 pin little chip) as a buffer, which has a 1:1 gain but the output is much lower impedance, i.e. can supply a higher currant
[20:52] <mattbrejza> tbh /10 is a bit ott, you only need /3 or so
[20:52] <Laurenceb_> i use a 100nF cap on the middle of the divider
[20:52] <Laurenceb_> to ground
[20:52] <ali_> i don't want to drain the the sucker, while trying to measure it :-)
[20:53] <Laurenceb_> a decoupling cap on the bridge allows you to use higher value resistors
[20:53] <eroomde> i'd follow the advaice of others - make the total resistance (r1 + r2) no more than low tens of kOhms
[20:53] <Laurenceb_> is low current draw is desired, and you dont want many samples
[20:53] <Laurenceb_> yeah - the simple way to sensure success
[20:54] <ali_> ok, so total about 50k, on a ratio about 10:1
[20:54] <ali_> am going with that, unless someone shouts
[20:54] <eroomde> 10:1 seems quite a lot as matt said - what is the voltage you want to measure and what is the voltage the adc is running off?
[20:54] <ali_> adc on arduino
[20:54] <eroomde> sorry if this is in the scrollback, i'm half watching mad men and half making some food
[20:55] <chrisstubbs> ali_, what batteries are you using
[20:55] <ali_> just looking to measure the battery during flight
[20:55] <chrisstubbs> 4x aa lithium?
[20:55] <ali_> ones from steve R
[20:55] <ali_> y
[20:55] <fsphil> the 10:1 was my suggestion (batteries up to 10v, vref at 1.1v)
[20:55] <eroomde> what is their voltage?
[20:55] <eroomde> ah righty
[20:55] <fsphil> but that's only useful in my case
[20:55] <eroomde> in the scrollback
[20:56] <ali_> so, i have about 6v
[20:56] <chrisstubbs> fsphil, i used the 1.1v int reference. Nothing else seemed to work...
[20:56] <eroomde> ali_: at 6V i'd just do 5:1

[20:57] <ali_> got a notam for launch from greenham common
[20:57] <ali_> old nuke site
[20:57] <ali_> looking for a windon on tuesday
[20:58] <ali_> a school project, so an absolute nightmare re organising kids/teachers etc
[20:58] <eroomde> that's a pretty funky place for a launch :)
[20:58] <ali_> i thought so too :-)
[20:58] <eroomde> yep, it can be tricky
[20:58] <ali_> i'm determained to make it happen
[20:59] <arko> organising people in general is difficult
[20:59] <eroomde> just remember the teachers are often sticking their necks out to do madcap balloon launchers that can go wrong, necessitating supply teachers and cover lessons and so on (often)
[20:59] <fsphil> opening a JPEG should not crash a computer. bad linux, bad
[20:59] <eroomde> it's a real boon to find a good teacher who is willing to take the risk
[20:59] <ali_> will need a hand to get the data sentence working on hab thingy
[20:59] <eroomde> a lot won't!
[20:59] <arko> fsphil: tell the curiosity rover
[21:00] <ali_> indeed. got the headteacher and head of science on board
[21:00] <eroomde> sounds like a win!
[21:00] <ali_> otherwise, i haven't even spoken to the physics teacher yet
[21:00] <chrisstubbs> ali_, i guess you know how the sentance should be formatted
[21:00] <ali_> sprintf(txBuffer, "$$$$$WASP-1,%u,%02u:%02u:%02d,%s,%s,%u,%u,%u,%i", record1.sequence_no, record1.hour, record1.minute, record1.second, trim(latString), trim(longString), record1.altitude, record1.velocity, record1.sats,batteryvoltage);
[21:01] <ali_> seems working right now:
[21:01] <ali_> $$$$$WASP-1,395,21:00:31,51.18423,-0.82029,171,0,6,1650*D0A5
[21:01] <chrisstubbs> looks perfect to me
[21:01] <ali_> getting a green light on dl-fldigi
[21:01] <ali_> but i need to get it showing on the map on tracker
[21:01] <chrisstubbs> in that case you need to head over to http://habitat.habhub.org/ and run genpayload
[21:02] <ali_> once i put in the other variables; temp, voltage etc, i'll get back on channel
[21:02] <chrisstubbs> you can then run Fldigi in HAB mode and it will appear on the map. then you file a flight dog and get an admin on here to approve it
[21:02] <ali_> yes chrisstubbs, i did it a while back, but will need to do it properly this time
[21:02] <Lunar_Lander> btw

[21:20] <chrisstubbs> Upu, heres to another one of my questions im sure you are sick of now :P
[21:20] <chrisstubbs> if using interrupts with the RFM22B. should you disable the interrupt while putting it into flight mode?
[21:21] <eroomde> joined just at the right time
[21:22] <Lunar_Lander> damn I missed it
[21:23] <fsphil> I'm not Upu, but I don't see why you'd want to chrisstubbs?
[21:23] <fsphil> do you mean GPS into flight mode?
[21:23] <daveake> What's the rfm got to do with flight mode anyway?
[21:24] <eroomde> what's radio got to do, got to do with it
[21:24] <fsphil> eroomde's gone radio gaga
[21:24] <Lunar_Lander> what does Q-Alpha steering mean?
[21:24] <eroomde> what's radio but a second hand peripheral
[21:25] <eroomde> Lunar_Lander: context?
[21:25] <daveake> He needs a secondhand emoticon
[21:25] <Lunar_Lander> the guy on the Atlas launch stream said it was enabled
[21:25] <chrisstubbs> haha. My code seems to get stuck in the main loop when it gets a fix and goes into flight mode. Im currently trying to figure out why
[21:26] <fsphil> possibly code for the bacon baps are ready
[21:26] <chrisstubbs> I thought it could have been the radio transmission interrupt that was messing up the serial message sent to the ublox telling it to go into flight mode
[21:27] <chrisstubbs> the code works perfectly (as far as i can tell) if i comment out the flight mode bit
[21:28] <fsphil> the rtty interrupt will have very little impact on anything
[21:28] <eroomde> Lunar_Lander: no idea
[21:28] <daveake> This three danger coded that worked perfectly before you plugged in the gps?
[21:29] <eroomde> q usually refers to dynamic pressure
[21:29] <daveake> Er the
[21:29] <chrisstubbs> daveake, sorry what do you mean?
[21:30] <daveake> Didn't you have trouble with rtty stoping when you had the gos plugged in?
[21:30] <daveake> Scuse my typing
[21:31] <chrisstubbs> I had trouble before with the serial buffer getting full while the string was being transmitted, so i switched to using interrupts instead of delays which solved that problem :)

[21:38] <ed__> Hi all im not sure if this is the correct place to ask but i have been reading lots lately about releasing a balloon. i seem to have confused myself somewhat and have a limited technological brain, but can anyone recomend specific products that i would need to get off the ground?
[21:39] <nigelvh> ed__ some of it will vary based on where you're located.
[21:40] <eroomde> gas (helium or hydrogen): rent a tank
[21:40] <ed__> ive got a tank on helium ;-)
[21:40] <eroomde> regulator - to take the very high bottle pressure down to something more suitable to inflate a balloon: rent
[21:40] <ed__> im in the uk nigelvh
[21:40] <eroomde> a hose to take the regulator output and put it into a balloon neck: build
[21:41] <ed__> got regulator
[21:41] <eroomde> see: http://ukhas.org.uk/guides:sealing_the_balloon
[21:41] <nigelvh> Then you have a lot of examples on the wiki about tracker options.
[21:41] <eroomde> i'm assuming that's what you mean byt the question =specifically filling
[21:41] <eroomde> if you mean more generally, that's a big question :)
[21:44] <ed__> hi sorry the bit that is getting me is things like gps systems tracking etc, i have bought a balloon but now think it may not be big enough, i think i have got the practical stuff sorted but like i say its things like gps refectors etc im confussed about
[21:46] <eroomde> that's the meat and potatoes of a launch really, the tracking
[21:46] <eroomde> so basically it works like this
[21:46] <eroomde> you want to know where your balloon is
[21:46] <eroomde> you need two things:
[21:46] <eroomde> 1) some way of the balloon knowing where it is
[21:47] <eroomde> 2) some way of the balloon telling you on the ground where it is
[21:47] <eroomde> (1) is handled by the GPS
[21:47] <eroomde> (2) is handled by a radio
[21:47] <nigelvh> Generally with a microcontroller (like an arduino) in the middle
[21:47] <eroomde> we tend to use a microcontroller to glue these two parts together
[21:47] <eroomde> we should say here and now, this will involve writing some software
[21:48] <nigelvh> Yes
[21:48] <eroomde> and you have to be prepared to do that for this shebang to work
[21:48] <ed__> ok so this is where i get confused but willing to learn
[21:48] <Willdude123> Chris Stubbs: I don't think I do.
[21:48] <nigelvh> There are examples available. But it's not a complete system.
[21:48] <eroomde> ed__: perfect
[21:48] <eroomde> then you've come to the right place
[21:48] <chrisstubbs> Willdude123, have a look, i only just found out there is one near me!
[21:48] <nigelvh> Do you have any experience with microcontrollers?
[21:48] <Lunar_Lander> ed__, also take your time
[21:49] <Lunar_Lander> I took from 2008 until 2013 to launch my first balloon
[21:49] <Lunar_Lander> xD
[21:49] <eroomde> don;t take that long ed__
[21:50] <ed__> brilliant therfore im probably looking at 2017??? :-)
[21:50] <ed__> i have no experience with mircocontrollers, i think this is wjhere
[21:51] <ed__> i could do with specifics about what products to use for someone with no experience in this
[21:51] <nigelvh> Personally, I'd recommend getting an arduino. There's LOTS of examples and support online for learning, and the arduino environment tries very hard to make programming easier.

[21:51] <nigelvh> I'd get that and play with it for a bit to learn about programming it.
[21:51] <ed__> ok so is arduino the product name
[21:51] <eroomde> yes
[21:51] <Upu> only joking
[21:52] <Upu> Arduino
[21:52] <eroomde> arduino is a kind of microcontroller called an AVR, which has been around for quite a long time, put on a board with all the support electronics it needs to run
[21:52] <ed__> PICAXE?????
[21:52] haircut (568507dd@gateway/web/freenode/ip.86.133.7.221) left irc: Quit: Page closed
[21:52] <eroomde> and more importantly it comes with software that makes it very easy to play with and program
[21:52] <Upu> it was a joke pls disregard
[21:52] <eroomde> ignore picaxe
[21:52] <eroomde> just forget you read it and don;t mention it again
[21:52] <Upu> many examples for Arduino out there
[21:53] <ed__> ok thanks for that i will have a look, cheers picaxe is forgotten about :-0
[21:53] BrainDamage (~BrainDama@dynamic-adsl-78-12-247-245.clienti.tiscali.it) left irc: Read error: Connection reset by peer
[21:53] <eroomde> so basically the arduino was invented as a way of making a common microcontroller very accessible and easy to use, and as such is ideal for HAB as it can do everything you want with a lower barrier to entry than there would otherwise be

[21:53] <nigelvh> Exactlt
[21:53] <nigelvh> y
[21:54] <eroomde> so we recommend it enthusiastically
[21:54] <eroomde> and you'll be in very fine company using it
[21:54] <nigelvh> Especially for someone unfamiliar with microcontrollers.
[21:54] <eroomde> then you'll need 2 additional major items
[21:54] <eroomde> the GPS and the radio
[21:54] <Upu> http://arduino.cc/en/Main/arduinoBoardUno
[21:54] <eroomde> again, we have our standard options
[21:55] <eroomde> other options exist but we like these for various reasons and you'll be able to get the most help if you use them
[21:55] <eroomde> the GPS we like is the UbLox Max6. The radio is the radiometrix NTX2. Upu sells both from his online shop which makes it much easier to get them if you're a hobbyist
[21:55] <Upu> hi
[21:56] <eroomde> so you don't need to mess around with minimum quantities or setting up accounts with distributors
[21:56] <ed__> brilliant thanks guys, ok so the radio is the physical radio used on the ground??
[21:56] <eroomde> there are guides on the wiki on how to physically connect these items to the arduino
[21:56] <eroomde> ed__: nope, the radio is the one that flies
[21:56] <eroomde> so the balloon can transmit
[21:56] <eroomde> on the ground the options are different
[21:57] <eroomde> '+' between the words upu
[21:57] <Upu> http://ukhas.org.uk/guides:linkingarduinotontx2
[21:57] <Upu> and this to test it
[21:57] <Upu> http://ukhas.org.uk/guides:sdr_tracker
[21:57] <Upu> it has worked without Ed but never mind
[21:57] <eroomde> on the ground we tend to use amateur radio equipment (there is a large overlap between habbers and amateur radio license holders) or the SDR upu just linked to
[21:57] <eroomde> the SDR is by far the lower cost option
[21:58] <eroomde> i have never seen it work without the '+'
[21:58] <ed__> i will look into all of these, thanks this is what im looking for, fantastic info so i dont end up buying stuff i dont need
[21:58] <Willdude123> Lol
[21:58] Action: Upu pats the bot
[21:58] <Lunar_Lander> ed__, I got an Arduino too
[21:58] <eroomde> she's on strike
[21:58] <Upu> it is broken :)
[21:58] <Upu> or on strike
[21:58] <Lunar_Lander> and by now I am starting to take like the AVR chip on it to standalone operation
[21:58] <Lunar_Lander> so I think you will be able to do so too in some time
[21:58] <Lunar_Lander> :)
[21:59] <eroomde> let's not confuse things yet Lunar_Lander
[21:59] <Lunar_Lander> yea
[21:59] <Upu> ed__ http://ukhas.org.uk/_media/general:hohoho-i-schematic2.jpg?cache=
[21:59] <Upu> thats basically it just ignore the mobile phone bits
[21:59] <eroomde> ed__: once you've got the gps and the radio physically connected to the arduino, you have to write some software to operate them
[22:00] <eroomde> this is the tough bit for most newcomers, but almost everyone succeeds if they accept that it won't be instant results and they have to allow some time to learn how to program
[22:00] <eroomde> it's the people who copy and paste the code examples on the wiki and then flail around with random edits that fail
[22:01] <eroomde> so make an oath to yourself right now - never ever, ever, ever copy and paste any code from the wiki
[22:01] <eroomde> read it, understand it, re-write manually
[22:01] <nigelvh> Use it as an excellent reference.
[22:01] <Upu> and the answer to your first 57 questions will be "http://ukhas.org.uk"
[22:02] <ed__> brilliant thanks for that i will take your advice and not do that!! i feel that this is the part which will give me the most problems!
[22:02] <eroomde> or RTFW which is the shorthand for ukhas.org.uk
[22:02] <Lunar_Lander> oh and please don't launch without authorization
[22:02] <eroomde> it's the part that gives most people problems, don;t worry. it's a lot to learn but it's not sort of fundamentally difficult, just a lot of new concepts if you've not done much before
[22:02] <Upu> just break it down into small chunks
[22:02] <Lunar_Lander> I think someone succeded to fly without that
[22:02] <Lunar_Lander> that was dangerous
[22:02] <eroomde> just a question of making a coffee and getting stuck in
[22:03] <ed__> thanks for that upu, but thats why i ended up on here as it was both very helpful but just lacked a little bit of help to explain in laymans terms how to go about doing things
[22:04] <ed__> no no i wont be doing that lunar_lander, not afgter all the effort i will be putting in with everything else!
[22:04] <Lunar_Lander> :)
[22:04] <eroomde> your experience with the wiki will be a nice analogy for the software i think
[22:04] <eroomde> don't be put off by the hundreds of lines of hyroglyphics
[22:05] <eroomde> it's really just a few very small and simply building blocks, you just have to understand how they fit together
[22:05] <eroomde> and we can help with that
[22:05] <Lunar_Lander> so, satellite separated
[22:05] <ed__> excellent thanks for that i look forward to my progress with this
[22:06] <Upu> where in the UK are you ?
[22:06] <ed__> im on the nottinghamshire derbyshire boarder
[22:06] <eroomde> ed__: if you want, and you have not done any programming before, and you don't yet know what words like 'variable' and 'function' mean in the context of computer programming, you might find it useful to have a go at an online course like Learn Python The Hard Way
[22:06] <Upu> oh nice and central
[22:07] <eroomde> not all of it, but the first half or so will give you the foundation you need to understand the shape of a computer program and how bits fit together
[22:07] <ed__> thanks eroomde i will look into this too
[22:07] <Upu> I'm in Halifax
[22:07] <Upu> just a bit further north than you
[22:07] <eroomde> it's a different programming language to the programming langiaged used by arduino (python and C++, respectively) but the language is not nearly as important as concepts of programming, which are pretty universal
[22:08] <eroomde> if you understand the latter, learning a new programming language can take just half a day
[22:08] <ed__> i will keep that in mind upu
[22:09] <ed__> thanks for that eroomde
[22:09] <Lunar_Lander> yea
[22:09] <Lunar_Lander> may I suggest an arduino tutorial?
[22:14] <Lunar_Lander> ed__, http://www.jeremyblum.com/category/arduino-tutorials/page/2/
[22:14] <ed__> ok so ive had a look at some of the very helpful links, can anyone give me a model number of which arduino they recomend as im unsure and also who is the best supplier of these
[22:15] <eroomde> Uno
[22:15] <eroomde> not sure who is the best supplier
[22:15] <nigelvh> I generally use Sparkfun
[22:15] <eroomde> try coolcomponents.co.uk
[22:15] <eroomde> they resell a lot of sparkfun stuff
[22:16] <nigelvh> They are US based, so probably slower than a UK supplier.
[22:18] <Lunar_Lander> hi nigelvh
[22:20] <nigelvh> Howdy
[22:20] <ed__> ok brilliant i will try both
[22:21] <Upu> when you come to buy the radio come speak to me
[22:22] <Lunar_Lander> btw Jeremy covers programming a GPS with arduino
[22:22] <Lunar_Lander> but it is not the same
[22:22] <Lunar_Lander> he uses TinyGPS to make an SD card tracker for his pocket

[22:33] <ed__> Thanks for this info guys i was just watching a tutorial!!! upu i was thinking of going ahead and buying a mircro controller, gps and radio all at once is this a bad idea?
[22:33] <Upu> not at all
[22:33] <Upu> quick PM
[22:33] <Lunar_Lander> ed__, let me guess
[22:33] <Lunar_Lander> a jeremy tutorial :)?
[22:34] <Upu> thats private message ed__, I should be blinking somewhere :)
[22:34] <Lunar_Lander> yeah if you use the webchat, at the top of the screen
[22:36] <ed__> got it thatnks
[22:36] <ed__> yep a jeremy tutorial
[22:37] <Lunar_Lander> yeah he is cool

[23:07] <chrisstubbs> Greatly sped up my time to first fix. Turns out you can never ahve enough decoupling capacitors :)
[23:09] <Lunar_Lander> cool
[23:16] <chrisstubbs> So you want to make a board with a standalone AVR lunar?
[23:18] <Lunar_Lander> yes
[23:18] <Lunar_Lander> i.e. from that board-arduino stack to a one-level board
[23:18] <chrisstubbs> Awesome :) Thru hole or SMD?
[23:18] <Lunar_Lander> thru hole
[23:18] <Lunar_Lander> :)
[23:19] <Lunar_Lander> I have one objection against SMD
[23:19] <chrisstubbs> Wise move :P
[23:19] <Lunar_Lander> if the chip dies it can't be exchanged easily
[23:19] <Lunar_Lander> at least I don't know an easy method
[23:19] <chrisstubbs> you can hot air gun it off and tidy the pads up with solder wick
[23:20] <Lunar_Lander> ah
[23:20] <chrisstubbs> At least with thru hole you can pull it out the chip holder
[23:20] <Lunar_Lander> yeah
[23:21] <chrisstubbs> My thru hole tracker was pretty fun to build. The ntx2 / ublox side of it was lovley
[23:22] <Lunar_Lander> yea
