[00:01] <Laurenceb> what are you using atm?
[00:03] <jcoxonnnn> something i got out of a sharp photogate
[00:03] <Laurenceb> ah ok
[00:04] <jcoxonnnn> but its pretty much buggered from prototyping
[00:04] <Laurenceb> pretty low power
[00:04] <Laurenceb> what resistor are you running it with?
[00:04] <jcoxonnnn> 47ohm
[00:04] <Laurenceb> at 3.3V ?
[00:04] <jcoxonnnn> yeah
[00:04] <Laurenceb> eek thats about 40ma
[00:05] <jcoxonnnn> i looked it up
[00:05] <jcoxonnnn> 20ma
[00:05] <Laurenceb> will fry your AVR if you draw more than 20ma from an IO
[00:05] <Laurenceb> ok
[00:05] <Laurenceb> you looked it up?
[00:05] <jcoxonnnn> in the photogate data sheet
[00:06] <jcoxonnnn> then calculated it
[00:06] <jcoxonnnn> (i burnt out another led recently so i'm paying attention!)
[00:08] <Laurenceb> ok

[08:24] <jcoxon> hows it going?
[08:32] <bittwist> nm
[08:32] <bittwist> scripting crap
[08:35] <jcoxon> urgh
[08:35] <jcoxon> finally finished my secondary board for my flight computer
[08:35] <jcoxon> nice stripboard/wire mess :-)
[08:35] <jcoxon> http://www.flickr.com/photos/jcoxon77/4142364434/
[08:36] <bittwist> nice
[08:53] <juxta> nice work on the daughterboard jcoxon
[08:53] <juxta> ah, I see you got your lassen IQ breakout made up too :D
[08:54] <jcoxon> yeah
[08:54] <jcoxon> i'm actually getting there with this payload
[08:54] <jcoxon> pretty much completely finished the hardware
[08:55] <jcoxon> just writing it up at the moment
[08:55] <jcoxon> http://www.pegasushabproject.org.uk/wiki/doku.php/missions:ballasthalo:ballasthalo3
[08:55] <juxta> nice :)
[08:56] <juxta> I wrote back to CASA re my launch jcoxon, just waiting to hear back from them again
[08:57] <jcoxon> okay cool
[08:57] <jcoxon> i'm sure it'll settle down
[08:57] <jcoxon> great news on the Ham who wants to help out
[08:57] <juxta> yeah
[08:58] <juxta> his sat tracking antenna array looks pretty awesome
[08:58] <jcoxon> he'll be a great asset
[08:58] <jcoxon> have you got round to testing the tracker yet?
[08:58] <juxta> not yet, possibly tonight :)
[08:59] <juxta> jcoxon - are you selling the lassen IQ breakout on seeedstudio?
[09:00] <jcoxon> ummm i open sourced it but haven't got round to emailing them the details
[09:00] <jcoxon> so i don't think its on there yet
[09:00] <juxta> ah okay
[09:01] <juxta> was it expensive to have it made up?
[09:02] <jcoxon> 30 US dolalrs
[09:02] <jcoxon> dollars*
[09:02] <jcoxon> and i'll get a rebate when i opensource it
[09:03] <juxta> that's pretty goodf
[09:03] <juxta> good*
[09:04] <jcoxon> yeah - it takes a while to deliever - might be quicker for you
[09:06] <juxta> I guess they're probably in HK or taiwan
[09:07] <juxta> which is usually not too bad for us
[09:07] <juxta> 1 week or so
[09:08] <juxta> I was thinking of having an audible alarm on the payload come on below 1000m, so we can find it if it lands in scrub, I was planning on buying one of those little personal alarms, but it looks like seedstudio have a little 110cb siren cheaply
[09:09] <jcoxon> the only issue we have with that is that you don't want to freak people out
[09:10] <juxta> that's a point, but then again we don't have the population density you do - it's unlikely there will be anybody within 10km of it when it lands
[09:11] <jcoxon> then perfect :-p
[09:11] <juxta> well, 10km is perhaps an exaggeration, but you get the idea :)
[09:16] <jcoxon> :-)
[09:16] <jcoxon> we should just all come down to australia for our launches
[09:16] <juxta> haha
[09:16] <juxta> well, don't rush down just yet, we've yet to see how CASA goes ;p
[09:18] <juxta> jcoxon: I'm thinking of getting an atmega running on it's own - I should just need a few passives and a clock, right?
[09:20] <jcoxon> i often refer to this: http://profmason.com/?p=611
[09:20] <jcoxon> and this: http://www.arduino.cc/playground/Learning/Atmega83-3V
[09:20] Action: jcoxon is speedy with his bookmarks
[09:22] <juxta> brilliant, I'll bookmark them :)
[09:22] <juxta> thanks jcoxon
[09:22] <juxta> oh wow, internal clock
[09:22] <juxta> excellent, I could make one tonight :D
[09:22] <jcoxon> yeah thats what i use
[09:23] <jcoxon> though you'll need to burn the bootloader
[09:23] <juxta> I have a couple of 328's kicking around already loaded with the arduino loader :)
[09:24] <juxta> oh actually, they'll have their fuses set for 16mhz
[09:24] <jcoxon> yeah but to use the internal clock you'll need to change the fuses
[09:24] <juxta> yeah
[09:24] <jcoxon> just need to use hte lilypad bootloader
[09:24] <juxta> ahh well, time to make up another parallel programer, my last one killed my atmegas ;p
[09:25] <juxta> back in a while, gonna have some dinner
[09:42] <jcoxon> right published schems so they might put it online soon

[10:00] <jcoxon> morning RocketBoy
[10:12] <gordonjcp> juxta: don't forget that the internal clock isn't very stable
[10:13] <juxta> gordonjcp: ah, I see - I didn't know. I'll probably get hold of a few 16mhz oscillators in any case
[10:14] <jcoxon> its not too bad - i haven't had any problems

[10:45] <sbasuita> DanielRichman, mmm
[10:45] <DanielRichman> sbasuita, any rangetesting today?
[10:46] <sbasuita> DanielRichman, the weather is miserable
[10:46] <DanielRichman> sbasuita, ok. No rangetesting today
[10:46] <DanielRichman> sbasuita, let's build a yagi (!)
[11:16] <RocketBoy> DanielRichman: have you got any yagi plans? - if not http://www.wa5vjb.com/yagi-pdf/cheapyagi.pdf is probably a good place to start - I have used the 434MHz 6 element version (bottom of page 2) of these antennas for locating rockets - and they seem to work well enough. The hairpin driven element is very simple to make.
[11:17] <RocketBoy> or a moxon is even simpler and quite good performance.
[11:17] Nick change: RocketBoy -> RocketBoy|Away
[11:19] <DanielRichman> RocketBoy|Away, thanks for the heads up.
[11:19] <DanielRichman> quick question - in those pictures, the coax - looks like the inner conductor is soldered to the driven element, but what about the outer-ground conductor?
[11:28] <DanielRichman> ah, RocketBoy|Away don't worry - i see now
[11:41] <RocketBoy|Away> np
[11:41] <DanielRichman> RocketBoy|Away, where do you recommend I get metal for the elements from? I'm having trouble finding some solid core 8AWG
[11:42] <RocketBoy|Away> 3mm brass rod (B&Q) is good
[11:43] <RocketBoy|Away> or you can get 1/8" (3.2mm) rod/tube from most model shops
[11:43] <DanielRichman> ok, thanks
[11:43] <DanielRichman> brass rod is an OK material to make a yagi? Copper is not required then?
[11:44] <DanielRichman> Would I have to adjust the elements to take account for the fact that brass has different resistance/speed of light etc.?
[11:44] <RocketBoy|Away> sure - copper, brass aluminium are all good
[11:44] <DanielRichman> ok, great
[11:45] <RocketBoy|Away> na - differences in conduction arn't a significant factor
[11:46] <RocketBoy|Away> brass is good for the driven element - cos you can solder to it
[11:46] <RocketBoy|Away> but aluminum is ok for eveything else
[11:46] <RocketBoy|Away> (lighter)
[11:46] <DanielRichman> Ah, ok
[11:47] <DanielRichman> This stuff? http://www.diy.com/diy/jsp/bq/nav.jsp?action=detail&fh_secondid=9283904&fh_view_size=10&fh_location=%2f%2fcatalog01%2fen_GB&fh_search=Brass+Rod&fh_eds=%C3%9F&fh_refview=search&ts=1259495216374&isSearch=true
[11:48] <DanielRichman> and then some of this
[11:48] <DanielRichman> http://www.diy.com/diy/jsp/bq/nav.jsp?action=detail&fh_secondid=9284092&fh_view_size=10&fh_location=%2f%2fcatalog01%2fen_GB&fh_search=Aluminium+rOD&fh_eds=%c3%9f&fh_refview=search&ts=1259495265363&isSearch=true
[11:49] <RocketBoy|Away> looks good - I thought they did 3mm
[11:49] <DanielRichman> Probably could ask for the 3mm in store
[11:49] <DanielRichman> since they won't deliver that stuff anyway
[11:51] <DanielRichman> How plausible is shrink fitting?
[11:51] <DanielRichman> I mean, we can produce at school a boom out of acrylic with holes at the correct poisitions
[11:52] <DanielRichman> but how cold would it have to get for shrinkfitting it in to be possible?
[11:52] <DanielRichman> considering also that it'd be a bit of a bummer if the elements just fell out on a cold day too
[11:54] <RocketBoy|Away> I don't know about shrink fitting - I used PVC for the boom and a dob of epoxy to hold them in place
[11:55] <DanielRichman> hmm ok. Probably will lasercut a acrylic boom with holes for the elements and just glue it
[11:55] <DanielRichman> thanks for your help :)
[11:56] <RocketBoy|Away> there are some longer 435MHz yagis on page 4
[11:56] <RocketBoy|Away> if you want more gain
[11:57] <DanielRichman> bigger the better :P. I eventually intend to roof-mount a yagi
[11:57] <DanielRichman> so might build a second one for portable use
[11:58] <RocketBoy|Away> good idea - let me know how you get on
[11:58] <DanielRichman> I just hope that at 5watts the EMC problems wouldn't b too bad with a yagi on the roof
[11:59] <RocketBoy|Away> for transmit check the swr with a swr bridge - and tune the length of the driven element for best SWR
[12:00] <DanielRichman> indeed
[12:00] <DanielRichman> and I imagine that having a good swr on the antenna also helps it receive.
[12:00] <DanielRichman> or, a good swr is a symptom of being good at receiving
[12:04] <RocketBoy|Away> yeah - good swr means the power is being efficently transferred - so that works in both directions TX and RX
[12:07] <RocketBoy|Away> its just measuring transmit SWR and tune is much much simpler to do than trying to tune based on receive performance.
[12:08] <DanielRichman> yep. I'm sure that i will be able to find a SWR meter int he local ham group
[12:08] <RocketBoy|Away> yeah - they are not too difficult to make either.
[12:17] <RocketBoy|Away> oh - just in case its not evident - place the SWR meter as near the antenna as possible - if you have it up the transmit end the co-ax beteen the SWR and the antenna "soffens" the readings
[12:17] <DanielRichman> ok

[14:17] <DanielRichman> hellom juxta
[14:17] <DanielRichman> *hello
[14:17] <juxta> hey
[14:17] <juxta> I was just going to mention that I'd been mucking around with yagi's in the last few days
[14:17] <DanielRichman> oh cool
[14:18] <juxta> I made up a couple - if you wanted to test something really simple, you could try something like this one:
[14:18] <juxta> http://projecthorus.org/wp-content/uploads/2009/11/IMG_3000.JPG
[14:18] <juxta> it uses a split dipole rather than a folded one, a little easier to make
[14:19] <DanielRichman> Hmm. What are the disadvantages/advantages to having a split dipole vs a folded one?
[14:20] <juxta> well, I'm no expert, but from what I understand:
[14:20] <juxta> folded dipole has advantages in that it offers a wide-ish bandwidth
[14:20] <juxta> and presents a nice impedence of 300 ohms, which you can match to 50 ohm coax using a balun
[14:20] <juxta> I made one with a folded dipole too, this one here:
[14:21] <juxta> http://projecthorus.org/wp-content/uploads/2009/11/IMG_3004.JPG
[14:22] <DanielRichman> :o nice
[14:22] <juxta> did a range test too, got 27.5km and I ran out of land :)
[14:22] <juxta> http://projecthorus.org/wp-content/uploads/2009/11/range2.jpg
[14:22] <juxta> (I was at the green tack)
[14:23] <DanielRichman> very nice
[14:24] <juxta> anyway - the little yagi I made up from plans I found on the net, took all of about 5 minutes and $2 in parts
[14:24] <juxta> I used coathanger wire, hehe
[14:24] <DanielRichman> :P
[14:24] <juxta> the larger one I used a calculator to come up with, it's made out of aluminium
[14:24] <DanielRichman> I see
[14:25] <juxta> you should have a look at yagimax and quickyagi, a couple of bits of old DOS software for designing and modelling yagi's, I've been having a play and coming up with some designs to build soon
[14:26] <DanielRichman> Hmm...
[14:26] Action: DanielRichman spots http://upload.wikimedia.org/wikipedia/commons/7/74/Dipolehalfwavebalun.png
[14:27] <juxta> yep, that's how I made my balun on the big yagi
[14:27] <DanielRichman> So if that's 4:1, that'd nicely match to a folded dipole style antenna
[14:27] <juxta> yeah
[14:27] <DanielRichman> great
[14:27] <juxta> but that little split dipole yagi has a impedence of ~50ohm anyway
[14:27] <juxta> according to my modelling at least :)
[14:27] <DanielRichman> indeed
[14:27] <DanielRichman> I will probably go for a split dipole
[14:27] <juxta> (so no balun needed)
[14:28] <DanielRichman> well if you're feeding it with coax...
[14:28] <juxta> from what I understand though, the impedence match is not so important for receiving in any case - moreso transmitting
[14:29] <juxta> #hamradio suggested it shouldn't really matter if the impedence is way off, so long as I only intend to receive
[14:30] <DanielRichman> Hmm. At some point i'd like to build a 2m antenna that is TX-worhty
[14:30] <RocketBoy|Away> be aware that placing a split (or folded) dipole in a yagi as the feed element will reduce its feed impedance quite a lot - the software models this and normally comes up with a way of matching the co-ax to the driven element
[14:30] <DanielRichman> local club has a net on their quite regularly
[14:30] <RocketBoy|Away> often the element spacing is adjusted to get a better match rather than increased gain
[14:30] <DanielRichman> RocketBoy|Away, " placing a split (or folded) dipole in a yagi as the feed element " - you imply that there is a third alternative?
[14:31] <juxta> DanielRichman: there are also 'hairpin' dipoles
[14:31] <RocketBoy|Away> well yes a matching device of some sort
[14:31] <DanielRichman> Ah right
[14:31] <juxta> RocketBoy|Away: ahh, that's a good point re the spacing being optimised for impedence
[14:31] <DanielRichman> hairpin: better than the other two? all the designs i have seen on the 'net so far use hairpin style atnennae
[14:32] <RocketBoy|Away> the hairpin design i suggested earlier has been designed to give a good match/gain
[14:32] <DanielRichman> hmm
[14:32] <DanielRichman> sounds like a better bet than me trying to get out the calculator
[14:32] <DanielRichman> considering I don't have anything with which i could properly design an antenna
[14:32] <RocketBoy|Away> the hairpin is a way of getting a balun as well
[14:32] <DanielRichman> oh, nice
[14:32] <juxta> DanielRichman: the dipole style has little effect on performance, so long as you build whatever you choose correctly, it's impedence that it'll effect, from what I understand
[14:34] <DanielRichman> ok
[14:34] <RocketBoy|Away> gamma matches are good for solving the matching/balun problem
[14:34] <juxta> RocketBoy|Away: is it true that an impedence mismatch isn't likely to impact on rx performance much?
[14:34] <RocketBoy|Away> (if you want to design your own - rather than an existing design - where all that should have been taken care of)
[14:35] <RocketBoy|Away> yes - as long as its not wildly out
[14:36] <juxta> as in +/-20ohm?
[14:36] <RocketBoy|Away> yeah - sounds ok
[14:37] <juxta> ah, great :)
[14:37] <RocketBoy|Away> with a long yagi a dipole can be dragged down as low as 10ohms
[14:38] <RocketBoy|Away> rather than 72
[14:38] <RocketBoy|Away> which it is in free space
[14:39] <juxta> a split dipole, that is?
[14:39] <juxta> or a hairpin/folded?
[14:39] <RocketBoy|Away> split dipole
[14:40] <RocketBoy|Away> is 72
[14:40] <juxta> ah alright
[14:40] <RocketBoy|Away> on rx any loss due to mismatch is normally more than outweighed by the increase in yagi gain
[14:41] <RocketBoy|Away> anyway GTG righ now - later
[14:41] RocketBoy|Away (n=Steve@217.47.75.8) left irc: "Leaving"
[14:41] <juxta> that's what I was wondering about - playing with designs, I can come up with a mismatched gain antenna with 1db or more gain above a matched one
[14:47] <juxta> DanielRichman: how is the payload coming along in any case?
[14:47] <DanielRichman> Hmm. Yagimax appears to have dissapeared off the internet
[14:47] <DanielRichman> juxta, finished!
[14:48] <juxta> DanielRichman: yagimax was a pain to find. gimme a second and I'll host it for you :)
[14:48] <DanielRichman> juxta, don't worry, i've got web.archive.org on my side
[14:48] <DanielRichman> actually, scrap that. Can you send it :P
[14:49] <juxta> hehe
[14:49] <juxta> http://projecthorus.org/yagi.rar
[14:49] <juxta> 2 versions of yagimax in there, as well as quickyagi
[14:50] <juxta> probably worth running it in dosbox also
[14:50] <DanielRichman> naturally
[14:50] <DanielRichman> RAR? what is this :P!
[14:51] <juxta> heh. tar.gz next time, I promise :)
[14:52] <DanielRichman> good ;P
[14:52] <juxta> this yagi calculator is good too:

[14:54] Action: DanielRichman drowns in information
[14:54] <DanielRichman> thank you very much ;) I've downloaded that file
[14:54] <DanielRichman> will install dosbox in a sec
[14:54] <juxta> no worries
[14:55] <juxta> a tip i found was to go through the dosbox config, and disable mouse lock, or whatever they call it - basically it means that if you click your mouse in the dosbox window, you then have to alt-tab out, you can't drag your mouse out
[14:56] <DanielRichman> mmm
[14:56] <juxta> also worth using ctrl+f12 to tell dosbox to ramp up the execution speed if you're trying to crunch numbers in quickyagi, otherwise it takes forever
[15:03] <DanielRichman> juxta, having serious problems unrarring that file
[15:04] <DanielRichman> none of the tools in the ubuntu repos like it one bit
[15:04] <DanielRichman> p7zip, unrar-free...
[15:04] <juxta> really? hmm, let me tar it then
[15:08] <juxta> DanielRichman: www.projecthorus.org/yagi.tar.gz
[15:09] <DanielRichman> juxta, thank you ver much
[15:09] <juxta> no worries
[15:25] <juxta> i'm off to bedm good luck with the yagi's DanielRichman
[15:25] <juxta> bed, *
[15:25] <DanielRichman> juxta, thanks for all your help

[22:04] <sbasuita> DanielRichman, yep
[22:05] <DanielRichman> sbasuita, gonna get antenna element materials next weekend on the way back from my foundation exam
[22:05] <sbasuita> DanielRichman, ok
[22:05] <DanielRichman> sbasuita, we'll probs have to make it in tech. Bending 4mm brass into a hairpin-dipole might b difficult
[22:05] <DanielRichman> tech has a flamethrowerything.
[22:09] DanielRichman (n=daniel@unaffiliated/danielrichman) left irc: Remote closed the connection
[22:28] <Randomskk> ic7000 or a new computer
[22:28] <Randomskk> choices choices
[22:28] <Randomskk> my paycheque finally came through, I could afford one or the other if I wanted to spend it all
[22:28] <Randomskk> and I kinda do
[22:28] <jonsowman> get both Randomskk
[22:29] <Randomskk> that would require both spending the entire paycheque and maxing out the credit card, not a great idea at the best of times
[22:29] <Randomskk> I think the icom has some ancillary costs too, like an antenna and stuff

[22:48] <Randomskk> my current computer is an 800mhz netbook :P
[22:48] <Randomskk> otoh my current radio is nil

[22:48] <Randomskk> while the icom?
[22:48] GeekShadow (n=Antoine@reactos/tester/GeekShadow) joined #highaltitude.
[22:49] <Randomskk> meant to ask about that, really, how often do these things come out?
[22:49] <edmoore> and computing power is everywhere if you need it
[22:49] <Randomskk> btw, I heard you're around for a bit after term ends?
[22:49] <edmoore> until 18th
[22:49] <edmoore> they come out far less frequently than computers
[22:49] <Randomskk> I'm here until.. tuesday evening
[22:49] <edmoore> ic-7000 is and will remain cutting edge for a fair bit, I think
[22:50] <Randomskk> yea
[22:50] <Randomskk> it's pretty awesome
[22:50] <edmoore> and ultimately it has good circuits in it, so it will last
[22:50] <edmoore> just like the 790 is still a great radio
[22:51] <Randomskk> my pc at home isn't even all that bad, but it's hardly great. 2gb ram, 2.2ghz single core, 5 years old, bit pants
[22:51] <Randomskk> beats the pants off this netbook though, I'm not using this for everything next term
[22:51] <Randomskk> doing anything in eagle is paaainful :P
[22:51] <SpeedEvil> My fastest PC is my x60s
[22:51] <Randomskk> vim takes a few seconds to loads
[22:51] <Randomskk> load*
[22:51] <Randomskk> like, what on earth
[22:51] <Randomskk> vim
[22:51] <Randomskk> load time in the seconds
[22:51] <SpeedEvil> vim?
[22:52] <Randomskk> the text editor
[22:52] <Randomskk> the console text editor
[22:52] <Randomskk> the one without a gui
[22:52] <SpeedEvil> I mean - yes - I know - seconds seems extreme
[22:52] <Randomskk> exactly
[22:52] <SpeedEvil> Unless you're in swap death
[22:52] <edmoore> we stopped off at junderwood's house yesterday
[22:52] <edmoore> it has a cool lair
[22:52] <Randomskk> I want my house to have a cool lair, when I get one
[22:52] <edmoore> space navigators are the best pc interface ever, it is official
[22:53] <Randomskk> oooh
[22:53] <Randomskk> are they that cool
[22:53] <Randomskk> did you use it with google earth
[22:53] <edmoore> yep
[22:53] <edmoore> and CAD
[22:53] <Randomskk> nice
