[00:00] <fsphil-laptop> imagine there's nothing left inside the hadie4 box now
[00:00] <daveake> nope
[00:02] <daveake> Anyone want the SM version of the RFM22B? Ordered the wrong one.
[00:04] <gonzo__> will the salt not wash out?
[00:05] <daveake> Looks like it's eaten part through some connections. Thos I can probably fix, but if it's eaten any copper tracks probably not
[00:05] <daveake> Everything's in a bucket of water now

[00:11] <Upu> daveake aren't they all SM ?
[00:11] <Upu> http://www.sparkfun.com/products/10153 this one ?
[00:12] <daveake> no - the one I flew is a little board with connectors along 2 sides (like the FSA03)
[00:12] <Upu> thats technically SM
[00:12] <daveake> OK, that's what I flew
[00:12] <gonzo__> i would have expected corrosion to take weeks, not hrs!
[00:13] <daveake> Power + salt water = much much quicker
[00:13] <daveake> Upu and what I thought I ordered
[00:13] <Upu> thats the ones I have
[00:13] <Upu> gonzo__ no Ava was in the water for 18 hours and the power pin on the NTX2 was totally corroded away
[00:14] <daveake> OK, I'll check what I actually have - it;s very thing and inside a sealed package I need to open
[00:14] <Upu> the metal connectors in the plastic battery holder disappeared

[00:36] <gonzo__> ah, elevrtolytic corrosoin, would speed it up.
[00:38] <gonzo__> a can of conformal coating would be a good investment
[00:38] <gonzo__> though, suppose the chances of it being a wet landing and recovered are slim
[00:39] <gonzo__> poss may help general protection though, and probs from conrensation.
[00:39] <gonzo__> I use it on my antenna termonations (matching networks etc in yagi's
[00:40] <gonzo__> anyway, gn all and congrats of both recoveries
[00:48] <SpeedEvil> Conformal is also good for humidity

[01:25] <Darkside> theres a big PSK contest going on in europe atm
[01:26] <WB8ELK> I hear VK land on 10 meters all the time via the Whisper program WSPR.net
[01:26] <Darkside> bah
[01:26] <Darkside> i don't like WSPR
[01:26] <Darkside> it does too much guessing
[01:27] <Darkside> like, it actually compares what it hears to a list of active calligns it pulls from the web
[01:27] <WB8ELK> well...I do see some very strange callsigns when it gets things wrong that's for sure
[01:27] <WB8ELK> but I think they try to filter out the bad stuff when it is displayed on their website
[01:28] <WB8ELK> I have mine running during the day on 10 meters and at night on 30 meters
[01:28] <WB8ELK> W3PM is 22 miles north of my farmhouse and he is running 10 milliwatts and I am copying him

[06:56] <SamSilver_> yes I followed all the flights yesterday
[06:57] <daveake> I took that; that's my wife in the photo :)
[06:57] <SamSilver_> ooopd
[06:57] <SamSilver_> ooops
[06:57] <daveake> s'ok lol
[06:57] <daveake> It's a bit blurred I know !
[06:57] <SamSilver_> you in a wet suit?? :p
[06:57] <daveake> :)
[06:58] <SamSilver_> true the blur pluss I forgot you had on faded jeans from the pic taken at launch
[06:58] <daveake> yeah
[06:58] <daveake> "loose fit" ones too
[06:58] <SamSilver_> bugger no pics of splash down
[06:58] <daveake> nope
[06:59] <daveake> I was looking forward to those
[07:00] <SamSilver_> adam the kid is making me look bad - I joined this irc before him and he has flown twice and I am still grounded
[07:00] <daveake> kids have more time :D
[07:00] <SamSilver_> but all on track this side
[07:00] <daveake> cool
[07:01] <SamSilver_> the x-files pic taken by the weathercam refers
[07:01] <daveake> I know!
[07:01] <daveake> Didn't see that till I got home
[07:01] <SamSilver_> if you look closly can you make out your wife to the right of the torch light

[07:02] <daveake> Yeah, a few pixels I noticed too
[07:02] <SamSilver_> afk for coffee back in 5
[07:02] <daveake> If so then that's when I caught up with here

[07:17] <SpeedEvil> Ah - nvm - bogon
[07:50] <MLow> so ive got my hx1 working
[07:50] <MLow> i can hear the packet coming from the trackuino over a mobile rig...
[07:50] <MLow> but no decode
[07:50] <MLow> and it sounds kinda slower than it's supposed to be
[07:56] <MLow> is there anything special i have to do with an hx1?
[08:09] <Darkside> MLow: no
[08:09] <Darkside> are you using the trackuino code?
[08:09] <Darkside> remember you have to set the cpu speed in config.h

[08:16] <SamSilver__> do tell
[08:16] <jcoxon> my SPoT works under 5cm of snow
[08:16] <SamSilver__> lol and in the cold
[08:16] <jcoxon> yeah
[08:17] <natrium42> nice
[08:17] <jcoxon> got a pic

[08:17] <jcoxon> hold on
[08:21] <number10> dont think I'll be getting my car out of the village, I put large amounts of salt on the path yesterday and snow settled on that :(
[08:21] <jcoxon> yeah
[08:21] <daveake> I hate salt :p
[08:21] <jcoxon> got gritted yesterday before the snow
[08:21] <daveake> Destroyer of payloads
[08:22] <jcoxon> daveake, debrief?
[08:22] <Upu> up down splash float (wrong sort) fish and chips YAY
[08:22] <Upu> morning
[08:22] <Upu> :)
[08:22] <Upu> not even looked outside yet
[08:22] <daveake> "Landed" ~ 300 metres offshaw; incoming tide and wind; eat f&c waiting for it to make land
[08:22] <MLow> Darkside: slightly modified, and it all works fine when hooked up to a mobile
[08:23] <daveake> offshore even
[08:23] <MLow> i have a breakout cable for ptt and mic on the mobile and it works fine with that, I show up on aprs.fi even
[08:23] <Upu> You'll be pleased to know RFM22 looks very viable jcoxon
[08:23] <daveake> Camera worked but filled up during descent due to a stupid mistake by some idiot
[08:23] <daveake> Video didn't work due to different mistake by same idiot
[08:24] <daveake> RFM22B worked really well though that payload died from salt attack on landing
[08:24] <jcoxon> Upu, excellent
[08:24] <jcoxon> heard it was a bit raspy
[08:24] <daveake> Main payload kept transmitting all the way till it beached
[08:24] <jcoxon> http://www.flickr.com/photos/jcoxon77/6821585903/in/photostream
[08:24] <daveake> At which point the water inside and/or waves washing over hit the tracker and stopped it
[08:25] <jcoxon> did anything survive the salt water?
[08:25] <Upu> you can still see the ground :)
[08:25] <number10> no ground in site here :)
[08:25] <jcoxon> Upu, thats my SPoT tracker which is still working
[08:25] <jcoxon> under snow
[08:25] <jcoxon> been out all night
[08:25] <Upu> oh lol missed that
[08:25] <daveake> Video did. It has seals (rubber ones, not oink oink ones) all over
[08:26] <MLow> Darkside: i dont see anywhere in the trackuino code to set the cpu speed
[08:26] <daveake> Trackers, camera, phone all kaput but I'm soaking/drying all to see if they recover
[08:26] <Upu> was the phone any use ?
[08:27] <jcoxon> was with water
[08:27] <jcoxon> then dry
[08:27] <daveake> Yes am doing
[08:28] <daveake> Phone worked before launch but not after. Don't know why .... the connector at the bottom possibly a bit loose.
[08:28] <Darkside> MLow: its a define in comfig.h
[08:29] <Darkside> config.h
[08:29] <MLow> F_CPU?
[08:29] <Darkside> maybe
[08:29] <MLow> i dont see a define for that in config
[08:29] <Darkside> hold on
[08:29] <Darkside> i'll find it
[08:29] <MLow> searched for cpu
[08:29] <MLow> only 2 hits for the buzzer
[08:30] <Darkside> hmm i think its elsewhere
[08:30] <Darkside> what crystal are you using
[08:30] <Upu> right best venture out bbl
[08:30] <daveake> Got some nice shots e.g. https://fbcdn-sphotos-a.akamaihd.net/hphotos-ak-ash4/431649_10150532801507654_695937653_8803231_1383014846_n.jpg on the way up.

[08:30] <Darkside> MLow: hmm ok it uses F_CPU to work out the playback rate
[08:30] <Darkside> so it should be working
[08:30] <Darkside> nice one daveake
[08:31] <daveake> And caught on webcam picking up the payload https://fbcdn-sphotos-a.akamaihd.net/hphotos-ak-ash4/394169_10150579772683880_681483879_9210610_573485701_n.jpg
[08:31] <Darkside> daveake: can hardly see anything
[08:31] <Darkside> lol
[08:31] <Darkside> or do you mean the torch
[08:31] <daveake> The blob is my torch
[08:31] <daveake> yes
[08:31] <daveake> BFO one
[08:32] <daveake> There was a clearer one earlier apparently but not captured
[08:33] <daveake> I'll do a flickr set and a blog write-up later today
[08:33] <Darkside> cool
[08:33] <jcoxon> cool cool
[08:33] <MLow> Darkside: lol, so should work...
[08:33] <daveake> Also need to make sure the rfm22b output level was set correctly
[08:34] <Darkside> :P
[08:34] <daveake> cloud antenna believed to be a bit bent at launch
[08:34] <daveake> which will account for some of the difference
[08:35] <daveake> 50mm of the antenna was inside the bottom of the payload, hence it was radiating nicely when it was floating in the sea
[08:37] <daveake> We were tuned to buzz till we lost that close to landing. Got nearer to the landing point and still nothing from buzz so I switched to cloud and got a faint signal. That got strong when we got close to the beach
[08:37] <daveake> We sat wondering what to do, then after a few minutes it looked like it was coming directly towards us. That was a nice moment :)
[08:38] <number10> nice picture daveake

[08:42] <number10> oh ok
[08:43] <MLow> what should the aref pin be connected to?
[08:43] <Darkside> nothing if youre not using it
[08:43] <Darkside> maybe connected to ground via a capacitor
[08:44] <jcoxon> natrium42, you'll need to delete the final few files

[10:51] <eroomde> we had a bit of rain ladt night
[10:51] <daveake> eroomde 5pm? Dunno when was that? Kinda lost track :)
[10:51] <eroomde> built an awesome snowman
[10:51] <eroomde> once you'd recovered it
[10:51] <eroomde> i then went out
[10:51] <daveake> :)
[10:52] <eroomde> we put sparklers in our snowman's head and he had his 20s of glory
[10:52] <eroomde> then it started raining and he's now a bit melted
[10:52] <daveake> Ah ok. Got the SD cards out then swapped drivers so julie wouldn't have to cope with the snow. Slow at bits on the M4.
[10:53] <daveake> Had about a minute of wheelspin going up a hill near here
[10:53] <daveake> Got some good photos from the camera
[10:53] <daveake> Lots of rubbish ones - lots of solid white cloud
[10:53] <daveake> But got some nice ones on the way up, and with the mooon
[10:54] <eroomde> nice
[10:54] <eroomde> why the whiteouts - in clouds or just all it could see were clouds?
[10:54] <daveake> latter
[10:54] <eroomde> uhuh
[10:55] <eroomde> yeah they're never the best
[10:55] <daveake> some angles there was some detail, but most just white.
[10:55] <eroomde> unless there's a really low sun that throws the texture into relief, or something
[10:55] <daveake> Did get that low down

[10:56] <eroomde> oh nice!
[10:56] <daveake> Had to up the contrast. Got a few like that
[10:56] <jolaw2> wow

[10:57] <jolaw2> great pictures :D
[10:57] <daveake> A few had some cloud detail - https://www.facebook.com/photo.php?fbid=10150532587282654&set=o.138475046220867&type=1&theater

[11:10] <fsphil> I'm after something a bit less permanent
[11:10] <Hiena> At the company we use two kind og noebook holder.
[11:11] <fsphil> I've got a dashboard mount for the eeepc but the battery in that died. annoyingly
[11:11] <CovBalloon> who's buying all the damned ft 817's on ebay? They are going for nearly the current retail price and you don't get the warranty.
[11:12] <CovBalloon> Morning everyone!
[11:12] <fsphil> CovBalloon, they always have
[11:12] <fsphil> it's total madness
[11:12] <Hiena> One is a glove gompartment mounted one. It's car specific, and block the view of the right seat.
[11:12] <jcoxon> sometimes it better to go for new
[11:12] <fsphil> one of the reasons I ended up just paying the extra and buying it
[11:13] <CovBalloon> I tried buying a new one from Greece but in the end they had no stock, possible consider Hong Kong but a little worried about the tax and import duty
[11:13] <eroomde> my housemate and her sister are babbling to each other in welsh
[11:13] <eroomde> it's the least parsable language ever
[11:13] <Hiena> The other is a tricky one, it's a pole fitted between the cupholder and the roof with a screw mechanism, and holds the notebook on an adjustable arm.
[11:13] <fsphil> yep :)
[11:13] <daveake> rtty is easier
[11:14] <eroomde> it sounds a bit like rtty actually
[11:14] <fsphil> don't you mean gwewwtchwgvvwwter daveake
[11:15] <daveake> Do the Welsh want special treatment or do they just want parity?
[11:15] <daveake> I'll get my coat
[11:15] <daveake> Nice breakfast :)
[11:15] <fsphil> ooch
[11:18] <CovBalloon> Did anyone launch their payloads this weekend?
[11:18] <daveake> nah, been very boring :p
[11:18] <fsphil> there where two launches CovBalloon

[12:09] <navrac2> excellent daveake
[12:09] <RocketBoy> hi daveake - not really I was there lurking
[12:09] <daveake> Ah OK :)
[12:10] <RocketBoy> another sea landing> very lucky
[12:11] <navrac2> I hope to see if I can do comms on 485 mhz from rfm to rfm on 125baud fsk 100mW
[12:12] <daveake> Yes, very lucky
[12:12] <daveake> I really thought I'd need to go find a boat, but whilst I was sat there thinking the payload starting coming directly to me
[12:13] <RocketBoy> any swimming involved ;-)
[12:13] <RocketBoy> ?
[12:13] <daveake> No :-).
[12:14] <RocketBoy> so how far out had it landed?
[12:14] <RocketBoy> (to sea)
[12:14] <daveake> We were just about to go out and look again with the big torch when the rtty abruptly stopped. That must have been when it washed up and the sea water got to the tracker (in the inside of the box lid)
[12:15] <SpeedEvil> 500m or so
[12:15] <daveake> 500m or so
[12:15] <daveake> ^^ :)
[12:15] <SpeedEvil> It probably blew 700m or so on a slightly curved track
[12:15] <daveake> yeah
[12:16] <SpeedEvil> I'm slightly surprised the surface wind was that different than the wind a couple of hundred meters up
[12:16] <SpeedEvil> Or maybe it changed
[12:16] <daveake> Really strong incoming wind where we were
[12:16] <daveake> At launch it went north then quickly turned and went south-sout-east
[12:17] <cuddykid> http://www.flickr.com/photos/acudworth/6822391575/in/set-72157629171216193
[12:17] <RocketBoy> I think it must win the prize for the luckiest launch
[12:17] <SpeedEvil> RocketBoy: naah
[12:17] <daveake> :D
[12:18] <cuddykid> the modified chdk worked very well :D
[12:18] <SpeedEvil> There was that one of a payload suspended over water in the netherlands, after crossing the atlantic
[12:18] <SpeedEvil> err
[12:18] <SpeedEvil> north sea
[12:19] <RocketBoy> yeah jcoxons - yep that was lucky
[12:19] <daveake> Oh, is that the one hanging from a tree, a few feet above a river?
[12:19] <RocketBoy> yeah
[12:20] <SpeedEvil> yeah. :) At least equally as lucky.
[12:20] <daveake> Remember seeing that a year ago when I started researching this hobby. Before I found this place I think
[12:22] <fsphil> I'm going to use that picture to demonstrate how not to land :)
[12:22] <fsphil> cuddykid, noticed you got a nice sequence of the moon rising
[12:23] <SpeedEvil> I'd have thought one of your own ones with the payload barely visible in trees would also be appropriate.
[12:23] <SpeedEvil> The moon is nice.
[12:23] <daveake> lol
[12:23] <cuddykid> fsphil: yeah, got quite a few of the moon :D
[12:23] <daveake> ditto
[12:24] <cuddykid> this one is definitely one of my favs http://www.flickr.com/photos/acudworth/6817672421/in/set-72157629171216193/
[12:24] <daveake> sky was largely featureless
[12:24] <cuddykid> daveake: we launched just at the right time :D
[12:24] <daveake> clouds I mean
[12:24] <cuddykid> lol
[12:24] <cuddykid> yeah, lots of clouds :(
[12:25] <RocketBoy> found it http://www.flickr.com/photos/jcoxon77/4383328360/in/set-72157623226106480
[12:25] <daveake> haha yeah, brilliant. That's the one I saw
[12:26] <daveake> I think that one wins :)
[12:27] <RocketBoy> yeah - but we should have a vote your flight yesterday should be 2nd place
[12:27] <daveake> I'll take that :D
[12:27] <Upu> lol
[12:28] <daveake> I really couldn't believe my luck when the tracker showed it coming directly towards me
[12:28] <Darkside> daveake: you were very lucky..
[12:28] <Darkside> ours was drifting away....
[12:28] <daveake> yeah I get that now :)
[12:28] <cuddykid> yet again - the predictor was remarkably accurate, the balloon followed almost the exact track
[12:29] <Upu> I updated it at 12:00 so it had the latest live prediction
[12:29] <daveake> Eroomde posted very quickly that it landed 15 mins after low tide
[12:30] <daveake> And when we got there the wind was very strong and almost direct from offshore
[12:30] <daveake> I planned for a quicker ascent but didn't have enough gas for that lift
[12:31] <SpeedEvil> I saw it going at 5.5m/s at one point
[12:31] <daveake> Also it burst a bit early and there's more land to hit further east
[12:31] <SpeedEvil> about 20km up I think
[12:31] <SpeedEvil> I thought.
[12:31] <daveake> 28km
[12:32] <daveake> Launch :-) https://fbcdn-sphotos-a.akamaihd.net/hphotos-ak-ash4/417130_269638876439131_100001790622484_670482_695847178_n.jpg

[12:38] <Upu> lol
[12:38] <daveake> A little yes, but nowhere near as much as on cloud1
[12:39] <daveake> cloud1 did come down quite quickly
[12:39] <cuddykid> It would be funny if the balloon shrouds just landed in the middle of a high street or on someones head lol
[12:39] <daveake> This was my first launch with not parachute tangling at all. I guess I should thank the tying team ;)
[12:40] <eroomde> we try our hardest
[12:40] <daveake> :)
[12:40] <daveake> number10 lol
[12:41] <cuddykid> I had a massive amount of tangling yesterday - I guess it was because I was doing the knots rather than the expert knots by WillDuckworth! - 1st launch (done by Will) didn't have any tangling
[12:41] <number10> you should pass on the techniques of parachute tying on a wiki page
[12:42] <eroomde> good knots would be good too

[12:45] <cuddykid> RockeyBoy: nope, just a very very twisted cord - I think some of the tangling was down to the cutdown module present at the apex of the chute
[12:45] <cuddykid> lol eroomde
[12:45] <eroomde> i think nylon tape or tubular nylon might help with twistage
[12:46] <eroomde> in that it transmits a lot more torque than a braided weave
[12:46] <eroomde> and so shouldn't tanlge and twist so much
[12:47] <Darkside> unlike your letters

[15:27] <cuddykid> what's the max power a holder of the lowest radio licence can transmit (on the ground) on the 70cm band?
[15:28] <joph> depends on the country ;)
[15:31] <gonzo__> uk, 10watts for novice
[15:32] <gonzo__> 50watts intermediate
[15:32] <gonzo__> 400watts full licence
[15:32] <gonzo__> and if you get a special research licence, 1kw

[16:34] <Upu> http://ukhas.org.uk/guides:guidelines
[16:34] <eroomde> also 'impact force' is appalling worded

[16:35] <eroomde> JESUS
[16:35] <eroomde> why do i never learn
[16:35] <daveake> whoops
[16:35] <NickB1_> because the person that processes the launch requests emailed me that it is a requirement to be classified as a light payload
[16:36] <NickB1_> but wheb I read the document he sent with the email it is only required when its a heavy payload
[16:37] <eroomde> NickB1_: best to ask him to expalin his reasoning given your reading of the rules
[16:38] <NickB1_> yeah going to give him a call tomorrow
[16:39] <NickB1_> I actually bought the rope from randomsolutions that complies with the 230N
[16:39] <NickB1_> but now he needs a lab test to prove it :)
[16:39] <eroomde> who is this person?
[16:40] <Upu> Are you in the UK NickB1_ ?
[16:40] <NickB1_> I'm from Belgium
[16:40] <Upu> Ah
[16:40] <Upu> just tell them it complies with ICAO regulations for light payloads

[16:51] <russss> err, my reading of that says that you *do* need the 230N requirement to be a light balloon
[16:51] gonzo_ (~gonzo_@109.104.96.45) joined #highaltitude.
[16:52] <russss> because a balloon is classified as heavy if it "uses a rope or other device for suspension of the payload that requires an impact force of 230 N or *more* to separate the suspended payload from the balloon."
[16:53] <NickB1_> I dont understand that
[16:53] <NickB1_> the light classification doesnt containt the 230N requrements ?
[16:53] <eroomde> in conclusion, make sure you first read it before telling him the bit you think that gives you an exemption :)
[16:54] <NickB1_> there is also a table on the next page
[16:54] <russss> light: an unmanned free balloon which carries a payload of one or more packages with a combined mass of less than 4 kg, *unless* qualifying as a heavy balloon in accordance with c) 2), 3) or 4) below
[16:55] <NickB1_> oh ok I understand it now :)
[16:55] <NickB1_> et needs te be less then 230N
[16:55] <NickB1_> *it
[16:57] <NickB1_> thanks!
[16:57] <NickB1_> hope randomsolutions can give me some documentation about the rope
[16:58] <cuddykid> 230N is a lot - the cord I use would break with far far less force than that :)
[16:59] <NickB1_> the rope from randomsolutions breaks at 220N
[16:59] <NickB1_> but I need to be able to prove it :/
[17:00] <cuddykid> I got mine from timstar lab solutions - works great
[17:00] <cuddykid> called braided nylon cord
[17:00] <Upu> are their suppliers who can certify the breaking force ?
[17:00] <cuddykid> NickB1_: do a vid hanging masses from the cord :P and show it breaks when 220N is the load

[17:08] <NickB1_> didnt think of that :D
[17:09] <RocketBoy> I really just sell the line as a way of UK HABers trying to conform to the specs if they wander out of UK airspace.
[17:09] <RocketBoy> yeah - the line doesn't need to break at 230N - but somthing needs to seperate
[17:09] <NickB1_> yes Belgium uses the same regulations as the US

[19:33] <cuddykid> Upu / others: are the surface mount resistors easy(ish) to solder? i.e. - should I be replacing the slots for standard resistors on my pcb?
[19:33] <eroomde> yes and up to you
[19:33] <eroomde> a more qualified answer is:
[19:34] <eroomde> i find everything down to and including 0603 ok to solder by hand and with my eyes
[19:34] <eroomde> 0402 i'd want some kind of magnification and really there is no point using 0402 unless you are very space constrained
[19:35] <eroomde> if using an iron, i wet the pcb pad first with a flux pen
[19:35] <eroomde> then some tweezers to place the part
[19:35] <cuddykid> ahh ok, thanks eroomde :)
[19:35] <eroomde> then with a wet soldering iron tip, still holding the part down with some tweezers, get it stuck on one side
[19:36] <eroomde> then remove the tweezers and solder the other side
[19:36] <eroomde> so, decent tweezers, a moderately fine soldering iron tip, and you'll be fine
[19:36] <eroomde> there's no particular skill at actual soldering over through-hole stuff
[19:36] <Laurenceb_> i use fingernail to hold it
[19:36] <Laurenceb_> but you have to be fast
[19:36] <eroomde> yes
[19:37] <eroomde> otherwise your finger hurts
[19:37] <Laurenceb_> fingernails conduct heat well :P
[19:37] <eroomde> you can use your tongue to clean the iron too
[19:37] <eroomde> instead of a damp sponge
[19:37] <Laurenceb_> haha
[19:37] <eroomde> but i would recommend a sponge
[19:37] <eroomde> and recomment tweezers :)
[19:37] <Laurenceb_> solder stencils are easy to get
[19:38] <Laurenceb_> but then you need a reflow oven or a very high end hot air station
[19:38] <Laurenceb_> luckily i have both
[19:38] <eroomde> actually the thing that's working really well for me recently
[19:38] <eroomde> is a plain hold hot air station
[19:38] <eroomde> and one of those ebay special pre-heaters
[19:38] <Laurenceb_> dont you blow everything away?
[19:39] <eroomde> so the preheater is like a quarts heating element over which you put the pcb
[19:39] <eroomde> which brings the entire pcb up to about 100-150C
[19:39] <eroomde> then the hot air gun gets the solder paste up to reflow temp much much more quickly
[19:39] <eroomde> a second or so
[19:39] <eroomde> Laurenceb_: never a problem
[19:39] <Laurenceb_> but doesnt the hot air blow it away?
[19:39] <Laurenceb_> oh
[19:40] <eroomde> i just go for high temp and lower flow rate
[19:40] <Laurenceb_> what station do you use?
[19:40] <eroomde> aoyue both
[19:40] <Laurenceb_> most stations i tried couldnt go low flow enough
[19:40] <Laurenceb_> im using a blackjack now
[19:40] <Laurenceb_> works well
[19:40] <Laurenceb_> one thing i found is you de need to approximate a proper profile
[19:41] <eroomde> for the oven?
[19:42] <Laurenceb_> with the air gun
[19:43] <Laurenceb_> otherwise you get fractures in the solder
[19:43] <eroomde> oh
[19:43] <Laurenceb_> if you cool too fast
[19:43] <eroomde> well, i think the pre-heater must help a lot with that
[19:43] <Laurenceb_> its not as bad on 0603
[19:43] <eroomde> will really reduce the cooling gradient
[19:43] <Laurenceb_> i see
[19:43] <Laurenceb_> larger ceramic parts seem to suffer
[19:44] <Laurenceb_> plastic ics are ok
[19:45] NickB1_ (~NickB@d54C3B15F.access.telenet.be) left irc:
[19:46] <Laurenceb_> also you need to be careful with footprints
[19:46] <Laurenceb_> thermals are good on the pads if you have gnd floods
[19:46] <cuddykid> brill - thanks eroomde :D
[19:46] <Laurenceb_> otherwise you can end up with different areas of copper wetted by the solder
[19:47] <Laurenceb_> and QFN/LGA parts might not make contact on all pads
[19:47] <Randomskk> eroomde: I tried using the hot air gun in the cusf lab to solder some stuff the other day
[19:47] <Randomskk> it didn't melt
[19:47] <Laurenceb_> thats an issue ive had
[19:47] <Randomskk> but no go
[19:47] <Randomskk> I think some of the flux started activating
[19:47] <Randomskk> but otherwise nothing
[19:47] <Randomskk> :|
[19:48] <Randomskk> in the end I did it by hand, it was a bga kinda thing but turned out to be just able doable
[19:48] <Laurenceb_> i run the air at 220C
[19:48] <Laurenceb_> then low flow
[19:48] <Laurenceb_> takes ~2minutes to preheat
[19:48] <Laurenceb_> then i try and cool over ~1minute by slowly moving the air gun away
[19:54] <eroomde> 220c is low
[19:54] <Randomskk> yea I was at like 290C
[19:54] <eroomde> i think pre-heating is pretty much the way to use hot air guns
[19:54] <eroomde> i.e. over a pre-heat bed
[19:56] <Laurenceb_> yeah i try not to overheat things
[19:56] <Laurenceb_> sometimes its a bit tricky at 220, so i use 230 or so
[19:57] <Laurenceb_> i usually use a large tool and come in ~5mm from the pcb

[20:06] <Upu> cuddykid everything eroomde said, I use 0603's for caps and resistors
[20:06] <cuddykid> great :D
[20:06] <Upu> you need tweezers and flux
[20:06] <cuddykid> thanks :)
[20:06] <Upu> and soldasip braid is great
[20:06] <cuddykid> got flux, just need some tweezers :)
[20:06] <Upu> get some ESD ones
[20:06] <fsphil> and nerves of steel
[20:07] <Upu> Soldering SMT stuff is much easier and you get way more sapce on the board
[20:07] <Upu> The nerves of steel come along when soldering expensive GPS units to the board
[20:07] <Upu> build it slowly test each bit along the way
[20:08] <eroomde> i highly recommend upu's advice of testing along the way
[20:08] <eroomde> especially if you build up the board in functionally logical steps
[20:09] <eroomde> so for example, the microcontroller and the crystal and the other essentials
[20:09] <eroomde> then test you can get an lef to blink
[20:09] <eroomde> led*
[20:09] <Upu> its quite easy with our designs as they are generally modular so you can test the microcontroller without putting GPS on
[20:09] <Upu> make sure the LED is pink
[20:09] <Upu> thats important
[20:10] <Hiena> The blue isn't hip anymore?
[20:10] <Upu> no :)
[20:10] <eroomde> pink - it was love at first sight
[20:10] <Upu> top tip if you're using AVR's
[20:10] <Upu> put an LED on the SCK pin
[20:10] <Upu> it blinks when you program it
[20:10] <Upu> and gives you something to test with

[20:11] <Lunar_Lander> hello
[20:11] <Upu> oh top tip no 2 just go download the Arduino Pro PCB and use that as a base
[20:11] <Upu> hey Lunar
[20:11] <Lunar_Lander> yay cuddykid and daveake
[20:11] <Lunar_Lander> hi Upu
[20:12] <cuddykid> :)
[20:12] <Upu> top tip number 3 make sure your RX and TX lines are the right way round
[20:13] <eroomde> :)
[20:13] <Upu> 4 make sure you leave enough space between the serial port and the ICSP so you can get both on at once
[20:13] <Lunar_Lander> what's tip 1?
[20:13] <Upu> 5 don't put vias under the battery
[20:13] <eroomde> i think Rx and Tx lines the wrong way round is a bit like leaving the chuck key in the lathe when you do some machining
[20:13] <eroomde> everyone does it once
[20:13] <eroomde> then never again
[20:14] <Upu> 6 don't use the DS18B21 part when you're going to use a DS18B20 the pin outs are totally different
[20:14] <Upu> this is just a list of stuff wrong with the Swift board :)
[20:14] <Upu> Lunar : [20:10] <Upu> put an LED on the SCK pin
[20:14] <Upu> [20:10] <Upu> it blinks when you program it
[20:14] <Randomskk> don't forget holes for mounting the pcb
[20:14] <Randomskk> don't forget pullups on i2c lines or USB D+ lines or the USB series resistors
[20:15] <Upu> what Randomskk said
[20:15] <Lunar_Lander> ah
[20:15] <Lunar_Lander> thanks :)
[20:15] <Randomskk> don't bother with pullups on AVR reset lines, they have them built in, but you might want a capacitor to DTR if you're using an FTDI connector
[20:15] <Upu> and just because Darkside isn't here, put decoupling capacitors on everything
[20:15] <Upu> In liverpool you'll get your wheels stolen if you sit about too long, in Darkside land you get decoupled
[20:15] <Lunar_Lander> XD
[20:16] <Lunar_Lander> is that liverpool thing true?
[20:16] <eroomde> yes
[20:16] <Lunar_Lander> ohhh
[20:17] <fsphil> it's why they keep going through red lights there, don't want to risk stopping
[20:17] <eroomde> more pcb tips then
[20:17] <eroomde> do a design rule check
[20:17] <eroomde> and actually understand all the errors
[20:18] <Upu> the Seeed studio one is pretty good
[20:18] <Upu> and it tents your vias
[20:18] <eroomde> i once made a big mistake as there were like 200 errors and 195 of them were fluff that you could ignore
[20:18] <fsphil> Upu, the serial port and isp headers are too close?
[20:18] <eroomde> but like 5 were proper
[20:18] <Upu> fsphil its tight they do go though
[20:18] <eroomde> but i just didn't see them in among all the tolerance crap
[20:18] <fsphil> ah
[20:20] <fsphil> http://www.flickr.com/photos/daveake/6824129787/in/photostream
[20:20] <eroomde> ADCs - RF is bitching and can get in
[20:20] <eroomde> add some rf filtering
[20:21] <fsphil> aliasing
[20:21] <eroomde> aswell as anti aliasing obv
[20:21] <eroomde> but get the rf right at the front by the connectorsa

[20:22] <eroomde> i have sometimes also made mistakes when designing pcb packages
[20:22] <eroomde> just in terms of mirror images and stuff
[20:22] <eroomde> so just double check
[20:23] <eroomde> part packages*
[20:23] <Upu> oh yes what eroomde said :)
[20:24] <eroomde> also with passives, it's nice having them all lining up in a row etc
[20:24] <Upu> don't pick a part labeled DS18B20 from someones library and assume is actually a DS18B20 :)
[20:24] <daveake> :)
[20:24] <eroomde> but don't squeeze them together too much - leave a bit of a gap between them - otherwise soldering them individually becomes very awkward

[22:10] <Darkside> MLow: thats interesting
[22:11] <Darkside> i think its the two on the right you need to worry about though
[22:11] <Darkside> i think the top one controls deviation, though i'm not 100%
[22:11] <Darkside> the other option you have is to attenuate the signal going into the HX1
[22:11] <Darkside> 5Vpp ay be too much
[22:12] <MLow> you mean like a voltage divider to get lower voltage ligic?
[22:12] <Darkside> in fact it probably is..
[22:12] <Darkside> yes
[22:12] <Darkside> i think 5Vpp is deviating too much
[22:12] <Darkside> if 3Vpp worked perfectly, 5V is probably too much

[22:16] <MLow> weird
[22:16] <MLow> why would the datasheet say it accepts 5v cmos logic..
[22:16] <Darkside> no, it does accept it
[22:16] <Darkside> just the deviation at 5Vpp is higher than what regular FM voice is
[22:17] <Darkside> i think regular FM voice has a 6KHz deviation, the HX1 is probably doing 10-15KHz
[22:17] <Darkside> so what you hear on your radio is probably more like a square wave
[22:18] jcoxon (~jcoxon@87.114.126.119) joined #highaltitude.
[22:18] <Darkside> as the discriminator will be clipping
[22:18] <MLow> i was looking at a waveform of it
[22:19] <Darkside> the output filters of your radio will probably smooth the waveform a bit
[22:19] <MLow> it looks about the same
[22:19] <jcoxon> ping fsphil
[22:19] <Darkside> still, try 3.3Vpp logic
[22:21] <MLow> fff
[22:21] <MLow> i guess i'll try a voltage divider
[22:21] <MLow> then use a chip if it works
[22:21] <Darkside> no point uing a chip
[22:21] <Darkside> voltage divider works just fine
[22:21] <MLow> smaller..
[22:21] <MLow> i mean for pcb
[22:21] <Darkside> 2 smd resistors?
[22:21] <MLow> 1 sot
[22:22] <Darkside> yeah, 2 0603s is smaller
[22:22] <MLow> truer signal
[22:22] <Darkside> uhm
[22:22] <Darkside> not really
[22:22] <MLow> just the same as you can drive a sd card with voltage divider, but not some
[22:23] <Darkside> in this case it'll work fine
[22:23] <MLow> low circuit impedance
[22:23] <MLow> basically
[22:26] <MLow> dont know if i can even solder a 0603
[22:28] <Upu> they are easy just a pair of tweezers needed
[22:29] <MLow> need to get some of those i keep hearing about em
[22:29] <MLow> mouser carry tweezers at a reasonable price?

[22:30] <Upu> and some of that
[22:30] <Upu> whats up with Sparkfun ?
[22:30] <Darkside> http://www.sparkfun.com/products/10603 I use that kind
[22:30] <MLow> ive got braid

[22:34] <MLow> they are anti-magnetic?
[22:34] <fsphil> why is the moon shot called "cheat"
[22:34] <MLow> what makes them esd safe? rubber?
[22:34] <fsphil> or was it, you've renamed it
[22:34] <daveake> I mooved the moon
[22:34] <Upu> I think the ESD ones are insulated with paint to stop static shooting down them into whatever you're holding
[22:35] <daveake> Yes I renamed it :)
[22:35] <fsphil> aaah
[22:35] <daveake> But it is a cheat :D
[22:35] <fsphil> still, you got a lot of detail on the moon
[22:36] <daveake> yeah, pleased with that
[22:36] <MLow> id imagine i can just spray some plastidip on it
[22:36] <MLow> vinyl spray
[22:38] <MLow> id rather not pay 4$ shipping for a pair of tweezers
[22:38] <MLow> and i dont have anything else to get from sparkfun
[22:39] <SpeedEvil> Not insulating plastic
[22:39] <SpeedEvil> Slightly conductive plastic
[22:39] <SpeedEvil> However.
[22:40] <SpeedEvil> If you work on a conductive mat (or a table sprayed with antistatic furniture polish), and ground yourself, conductive tools are just fine
[22:41] <MLow> yeah im not sure if my desk meets that
[22:41] <MLow> or if im every properly grounded short of holding the negative terminal in my house(which i regularly do)
[22:42] <SpeedEvil> make a ESD strap
[22:42] <SpeedEvil> just some metal going onto your body - a button or something - with a 1M resistor to ground

[22:45] <MLow> ive always just not cared about static
[22:45] <MLow> like in a pretty humid area, it's rare to see static unless it doesnt rain a long time
[22:46] <Dan-K2VOL> you don't need to see static to destroy an ESD sensitive chip
[22:46] <Dan-K2VOL> Ok, it's movie time - 1980s introduction to ESD, by none other than Apple Computer's repair division: http://www.teachertube.com/viewVideo.php?video_id=16012&title=Apple_ESD_video
[22:47] <MLow> no more tabs
[22:47] <MLow> please god
[22:47] <Dan-K2VOL> haha
[22:47] <Dan-K2VOL> today there are parts that still can be damaged by 200v of ESD, and you'll never see, hear, or feel that shock
[22:48] <Dan-K2VOL> for example, the ANTENNA port of the Micrel MICRF405 433 mhz transmitter :-)
[22:48] <Dan-K2VOL> so it can affect you
[22:49] <Dan-K2VOL> however, there's never any direct evidence you can point to that says your part is behaving poorly or not at all because you ignored ESD protection
[22:50] <Dan-K2VOL> if you have a rare situation you may have circumstantial statistical evidence, such as one time at work I had a technician come to me and say that all the boards he did today were dead (!)
[22:51] <MLow> it just seems like ESD coating is a bit of a scam
[22:51] <MLow> conductive plastic? then whats the point
[22:51] <Dan-K2VOL> I had him show me how he was working, and he brought me to a new desk that had been installed, and I saw him slide 5 repaired 1990 car remotes a half meter across the plastic desktop into a box. Everytime he slid one across the table, it was destroyed
[22:51] <Dan-K2VOL> add ESD mat and grounding strap, problem solved
[22:51] <Dan-K2VOL> are you watching the video?
[22:52] <Dan-K2VOL> you need to if you don't believe in ESD
[22:52] <BrainDamage> lol @ believe in ESD
[22:52] <Dan-K2VOL> hehe
[22:52] <BrainDamage> are there any ESD-based religions?

[22:55] <SpeedEvil> 'never' may be strong. ESD can be found by decapping the chip, and microscopy.
[23:06] <MLow> oh i believe it's real i just think that tools marketed at ESD safe are full of it...
[23:06] <eroomde> i know someone who *was* formerly in an ESD religion
[23:06] <MLow> i may be wrong but it just looks like a plsatic/rubber coating
[23:06] <eroomde> he was _ex-static_ to have left
[23:07] <MLow> :|
[23:07] <MLow> leave
[23:07] <BrainDamage> I had couple things damaged by esd, but I find with most parts, you'd have to try hard to damage them
[23:09] <MLow> especially a resistor
[23:13] <fsphil> sounds like a challange
[23:17] <Darkside> eroomde: bad.
[23:18] <fsphil> I was shocked to hear that one
[23:18] <Darkside> >_>
[23:18] <Darkside> <_<
[23:18] <fsphil> well I thought it had potential
[23:19] <Darkside> yep ok

[23:34] <Darkside> just try a 10k and 10k
[23:34] <Darkside> and see if you can get it to under-deviate

[23:37] <MLow> nothing yet
[23:37] <MLow> did 9k and 9k
[23:38] <Darkside> not sure MLow, mine just works...
[23:39] <fsphil> how is it connected? the HX1
[23:40] <MLow> how the data sheet says
[23:40] <MLow> what do you mean
[23:40] <Darkside> MLow: are you feeding the PWM output from the AVR straight into the HX1 (via the voltage divider)
[23:40] <fsphil> I mean, are you driving it from a microcontroller pin or an audio source?
[23:40] <Darkside> and is the enable pin locked high
[23:41] <MLow> yeah i am listening to it via a mobile and HT
[23:41] <MLow> ht has antenna off so it's definitely working
[23:41] <MLow> im decoding with agwpe
[23:42] RocketBoy (~steverand@5acfd4fd.bb.sky.com) left irc: Quit: RocketBoy
[23:42] <fsphil> I'm wondering because you can't feed an audio signal straight into the hx1

[23:45] <Darkside> MLow: are you capacitively coupling the signal anywhere
[23:45] <Darkside> because you shouldn't be
[23:45] <MLow> no
[23:45] <Darkside> ok
[23:45] <Darkside> then it should work
[23:45] <MLow> straight line to the divider and then into the hx1 txd pin
[23:45] <Darkside> check you haven't compiled the code with the wrong cpu frequency setting
[23:46] <fsphil> Lunar_Lander, he looks at himself in the mirror. fake :)

[23:50] <NigeyS> hi
[23:50] <MLow> Darkside: where in the trackuino code is the cpu speed
[23:50] <Darkside> it isnt
[23:50] <Darkside> it uses F_CPU
[23:50] <MLow> ah in boards.txt then
[23:50] <Darkside> no
[23:50] <Darkside> youc an choose it from the drop down list
[23:51] <Darkside> you have a custom pcb, right?
[23:51] <MLow> bread board right now
[23:51] <Darkside> what crystal frequency
[23:51] <MLow> 16mhz
[23:52] <Darkside> what do you have selected in tools -> bords
[23:52] <Darkside> boards*
[23:52] <MLow> my own board
[23:52] <Darkside> you shouldn't need to do that
[23:52] <Darkside> but anyway
[23:52] <Darkside> make sure the frequency is set corretly
[23:52] <Darkside> i dunno what it defaults to
[23:53] <MLow> i fail to see how it would work with a different radio if the frequency was wrong
[23:53] <MLow> atmega328.build.f_cpu=16000000L
[23:53] <Darkside> MLow: if the frequency is set incorrectly, the timing for the tone generation will be off
[23:53] <Darkside> and it will generate incorrect tones
[23:53] <MLow> im talking about hooking this directly into a different radio
[23:53] <MLow> and it works
[23:53] <MLow> same code
[23:54] <MLow> same atmega
[23:54] <Darkside> then thats a deviation problem
[23:54] <MLow> roger
[23:54] daveake (daveake@daveake.plus.com) left #highaltitude.
[23:54] <Darkside> or something wrong with how you're driving it
[23:54] <MLow> thats why i was trying to clairify
[23:54] <Darkside> whic is weird - i have no problems
[23:54] <MLow> well it's weird cause now i've driven it with 3 different voltages and it doesnt work

[23:55] <fsphil> this is where a scope comes in handy
[23:55] <MLow> well i am looking at a waveform of the output on my laptop
[23:55] <MLow> but thats through the mobile
[23:56] <fsphil> what voltage are you providing the hx1?
[23:56] <fsphil> for power
[23:56] <Lunar_Lander> ROFL NigeyS
[23:56] <MLow> 5v
[23:56] <MLow> like 5.14
[23:58] <MLow> i had to change the timing in radio_hx1.cpp
[23:58] RocketBoy (steverand@5acfd4fd.bb.sky.com) left #highaltitude.
[23:58] <MLow> it says it takes the hx1 5ms to go full rf but with 5ms it cuts off most of the transmission
[23:59] <Darkside> i think i modified that
[23:59] <Darkside> to give more of a delay before starting to transmit
[23:59] <MLow> yeah i did like almost a second lol
[23:59] <fsphil> I've mine at 50ms
