[00:00] <Lunar_Lander> oh
[00:01] <Lunar_Lander> yeah what will happen now they launched unauthorized?
[00:01] <Randomskk> oh wow
[00:01] <Randomskk> that's one heck of a close miss
[00:02] <griffonbot> Received email: Adrian Hicks "Re: [UKHAS] Balloon footage."
[00:04] <NigeyS> wow talk about super close!!
[00:05] <jonsowman> unbelievably close
[00:05] <Lunar_Lander> yea but now my question
[00:05] <Lunar_Lander> what now?
[00:06] <Randomskk> 50 years hard labour in the gulag
[00:06] <NigeyS> hah!
[00:06] <NigeyS> soap!
[00:07] <fsphil-laptop> that was very hab hazard of them
[00:07] <jonsowman> :|
[00:07] <fsphil-laptop> ah man, daveake isn't even here for that one
[00:07] <jonsowman> oh dear
[00:07] <NigeyS> you see the plane on the way down ?
[00:07] <Randomskk> no... time?
[00:07] <NigeyS> lemme check
[00:07] <NigeyS> can just make it out center screen, greyish smoke to
[00:08] <NigeyS> 8:50 onwards it pops in and out of view
[00:09] <Randomskk> :|
[00:10] <Lunar_Lander> damn
[00:10] <Lunar_Lander> what if flight control now bans HAB?
[00:11] <fsphil-laptop> I don't see it
[00:11] <NigeyS> fsphil-laptop, its quite hard to spot, might be a gap in the cloud ? though looks plane ish to me
[00:12] <NigeyS> Lunar_Lander, lets not over react :-)
[00:12] <Lunar_Lander> yea
[00:12] <Lunar_Lander> but who is that one guy again who has the contacts?

[00:18] <Randomskk> it hasn't been trimmed in quite some time

[03:01] <heathkid> that's the same old russian tube you can get with the kit from goldmine-elec.com
[03:01] <heathkid> I've got a few of those
[03:01] <heathkid> nice tubes
[03:01] <heathkid> not sensitive to Alpha though
[03:02] <heathkid> and I've YET to see a decent design
[03:02] <heathkid> the power supplies are all over the place
[03:03] <heathkid> and that shows it running off 3V? really?
[03:03] <Lunar_Lander> I guess so, there are only two batts
[03:03] <heathkid> I understand there is a step-up... but really?
[03:03] <Randomskk> what's wrong with that?
[03:04] <heathkid> nothing
[03:04] <heathkid> site says: » Support for several common Geiger-Müller tubes: SI-3BG, SI-1G, and SBM-20. HV supply can be adjusted from ~300-600V.
[03:04] <heathkid> nice
[03:04] <heathkid> the SBM-20 can be bought in bulk
[03:04] <heathkid> nice tube
[03:05] <heathkid> but most kits don't have an adjustable power supply
[03:05] <heathkid> this looks nice
[03:05] <Lunar_Lander> yea
[03:07] <Lunar_Lander> $50 on the electronics goldmine
[03:11] <heathkid> I've got the C6999 (World's Tinest Geiger Counter)
[03:11] <heathkid> from them
[03:11] <heathkid> it IS tiny
[03:11] <heathkid> and works
[03:11] <heathkid> but no data logging (unless you put a buffer on the LED and add some other goodies)
[03:12] <heathkid> but it's tiny
[03:12] <heathkid> but... the MightyOhm does look nice
[03:12] <heathkid> the serial out is a bonus
[03:12] <heathkid> so I just ordered one
[03:12] <heathkid> :)
[03:13] <heathkid> didn't have that one yet
[03:13] <heathkid> have all the electronics goldmine ones, and one from SFE
[03:13] <heathkid> plus the old Victoreen ones
[03:13] <Lunar_Lander> COOL
[03:14] <heathkid> I got a really nice one with a lot of new parts I need to put in it to completely restore it
[03:14] <heathkid> including a NOS knob
[03:14] <Lunar_Lander> yea
[03:14] <heathkid> my only source is a piece of ore... but it's calibrated at 31k cpm
[03:14] <heathkid> seems pretty spot on too
[03:14] <Lunar_Lander> yeah
[03:14] <Lunar_Lander> U I think?
[03:15] <Lunar_Lander> or Th
[03:15] <heathkid> U
[03:15] <Lunar_Lander> yea
[03:15] <heathkid> got it from united nuclear
[03:15] <heathkid> when they had it
[03:15] <Lunar_Lander> yeah, I know these
[03:16] <heathkid> not sure exactly what it is (it's in a nice lead box most of the time... and out in garage which is on a seperate lot than our house)
[03:16] <heathkid> lead lined box
[03:16] <Lunar_Lander> yea
[03:16] <heathkid> but it'll light up any of my counters so I know it's good for testing
[03:17] <heathkid> my goal is to build a robot to find it
[03:18] <Lunar_Lander> cool
[03:22] <heathkid> that looks like a very nice kit
[03:22] <heathkid> and I do like the SBM-20 tube
[03:22] <heathkid> it's built like a tank
[03:22] <heathkid> and that kit will let me play with various tubes... nice
[03:23] <heathkid> the HV circuits on the other kits just don't seem to work right
[03:23] <heathkid> plus this has serial out... very nice
[03:23] <Lunar_Lander> yea
[03:23] <Lunar_Lander> :)
[03:23] <heathkid> it's a bit large... but good for prototyping

[03:29] <heathkid> I know it's not really funny... but really?
[03:30] <heathkid> none of my "kits" have enclosures and especially the SBM-20 only tickles slightly (hardly noticible)
[03:30] <heathkid> sometimes I get bette readings when I'm touching both ends of the tube
[03:30] <heathkid> lol
[03:31] <heathkid> but on this one I went ahead and got the laser cut acrylic enclosure... just becuase it looks nice
[03:31] <heathkid> :)
[03:32] <heathkid> and no, I don't usually try to be a resistor across a HV circuit...
[03:33] <heathkid> ;)
[03:33] <heathkid> but some of the cheap kits really need a redesign on the HV circuit

[03:36] <Lunar_Lander> I read about that train driver at Deal
[03:36] <Lunar_Lander> he drove a train from Dover to Deal and there is a steep climb and then a steep descent

[03:37] <Lunar_Lander> turned out that the oil on the brake blocks had burned away, but there was a new block that turned rusty in storage
[03:37] <Lunar_Lander> and actually looked like it was glowing red
[03:37] <Lunar_Lander> (but had it been glowing, there would have been damage to the other parts of the brake system)
[03:38] <Lunar_Lander> well, the driver didn't want to go all around the train and tried to climb through between the wagons
[03:38] <Lunar_Lander> then, his arm touched the bumper and his leg touched the third rail, completing the circuit
[03:38] <Lunar_Lander> and he died
[03:44] <heathkid> :(
[03:44] <heathkid> it's not the volts... it's the amps...
[03:45] <heathkid> trust me... I've hurt myself with a 1.5V AA battery!
[03:46] <heathkid> of course it was stepped up and discharged via a bank of photo caps...
[03:46] <heathkid> and don't work on tube amps in a basement with a concrete floor in bare feet! *just trust me*
[03:46] <SpeedEvil> heathkid: I've hurt myself with a 1.2v AA cell.
[03:47] <SpeedEvil> heathkid: A teeny wire got across a failed spot in the insulation, and burned ~1cm of my finger.
[03:47] <heathkid> SpeedEvil: sorry but also good to hear. most people think I'm nuts!
[03:47] <SpeedEvil> Still there.
[03:47] <SpeedEvil> No caps or anything
[03:48] <heathkid> a AA battery may not be capable of killing you... but they certainly can burn/hurt you!

[03:51] <Lunar_Lander> yea
[03:52] <Lunar_Lander> SpeedEvil: had something similar too
[03:52] <Lunar_Lander> I pressed a wire on the negative terminal of the battery and only a few seconds later, I noticed the bright light at the end of the wire
[03:52] <Lunar_Lander> but then the wire already had burned a "trench" into my fingertip
[03:53] <SpeedEvil> Mine - the insulation of the top of the cell had failed - and bridged from the case to the positive
[03:53] <Lunar_Lander> yea
[03:53] <SpeedEvil> I was trying to hold a (different) wire onto teh positive and negative
[03:53] <Lunar_Lander> oh

[03:54] <Lunar_Lander> and he used a camera flash unit for an ignitor and was working on that in the basement when there was a loud bang and he fell unconscious
[03:54] <Lunar_Lander> his doc later told him that those 400 V went through him
[03:57] <schofieldau> I've seen tutorials online for homemade non-lethal tasers using disposable camera flashe
[03:57] <SpeedEvil> The hard part of taser is the non part.
[03:57] <SpeedEvil> A straight DC pulse isn't very nonlethal
[04:02] <Lunar_Lander> yea
[04:02] <heathkid> no kidding
[04:03] <Lunar_Lander> the stupidiest thing I once saw on one of these TV "telenovelas"
[04:03] <Lunar_Lander> there was a wedding and one guy made like cards for that or so
[04:04] <Lunar_Lander> and a woman was helping him but she was actually trying to sabotage the wedding
[04:04] <Lunar_Lander> and when he was looking for something on the desk, she threw a glass of water into the PSU fan of the PC
[04:05] <SpeedEvil> screen letters dripping effect?

[04:05] <schofieldau> card photoshop files deleted?

[04:05] <Lunar_Lander> and he looked flabbergasted
[04:05] <SpeedEvil> ah
[04:05] <Lunar_Lander> and she "oh. seems to be a malfunction"
[04:06] <SpeedEvil> you can actually get sparks with water
[04:06] <Lunar_Lander> yea
[04:06] <Lunar_Lander> but I assume
[04:06] <Lunar_Lander> if you would really pour water into a PC, that would rather trip the breakers of the house
[04:08] <Lunar_Lander> I have a three-lamp ceiling lamp here
[04:09] <Lunar_Lander> with halogen lamps
[04:09] <heathkid> unless it's good DI water...
[04:09] <Lunar_Lander> and I had it twice when I switched on the lights, there was a bang, a ring of fire or so in the middle lamp
[04:09] <Lunar_Lander> and the breaker tripped
[04:09] <SpeedEvil> Lunar_Lander: It varies.
[04:09] <SpeedEvil> Lunar_Lander: Here, it wouldn't.
[04:09] <SpeedEvil> It would at best blow the fuse in the plug.
[04:09] Action: heathkid doesn't water cool PC's anymore...
[04:09] <Lunar_Lander> oh
[04:09] <SpeedEvil> There is no RCD in the house

[04:10] <SpeedEvil> On that circuit
[04:10] <Lunar_Lander> but it wouln't be live anymore because of the plug fuse?
[04:10] <SpeedEvil> indeed.
[04:10] <Lunar_Lander> ah
[04:10] <heathkid> I had a pump fail and the water hit the front inlet fan
[04:10] <Lunar_Lander> ohhhh

[04:18] <heathkid> my dad was in the US Army and stationed there when I was born... but couldn't make it to the base before I was born (so I was born in a German hospital)
[04:19] <Lunar_Lander> yea
[04:19] <heathkid> I like Australia too
[04:19] <Lunar_Lander> and england

[04:19] <Lunar_Lander> xD
[04:20] <Lunar_Lander> brb, kitchen
[04:20] <heathkid> though you can't get really good Ranch salad dressing there! lol
[04:20] <Lunar_Lander> xD yeah
[04:23] <heathkid> now I just need to convince the guy at work to let me bring in a Uranium Ore sample... put it and a geiger counter in our high altitude chamber... and see where (if) it fails.... right?
[04:23] <heathkid> I'll need to keep it packaged pretty well... we've got dosimeters *everywhere*!
[04:24] <heathkid> primarily for x-ray but I work with hard x-ray so gamma will show up pretty easily on those
[04:24] <heathkid> no one cares about alpha
[04:24] <heathkid> beta? hah
[04:25] <heathkid> a pair of jeans and your're good
[04:25] <heathkid> but hard x-ray and gamma... not so nice
[04:25] <heathkid> the live x-ray I use almost every day I use at about 170KeV
[04:28] Action: SpeedEvil wishes he had an x-ray.
[04:28] <heathkid> and of course the 1/4" of borosilicate (sp?) glass stops everything... ;)
[04:28] <heathkid> x-ray easy
[04:28] <heathkid> lots of early vacuum tubes produce x-rays
[04:28] <SpeedEvil> I want to use it to inspect my balls.
[04:28] <SpeedEvil> And my other sorts of soldering.
[04:29] <heathkid> yea, we use it for the solder balls too...
[04:29] <heathkid> but the resolution really isn't good enough
[04:29] <heathkid> so it's cross-sectioning...
[04:29] <heathkid> a few nm at a time and under very high mag
[04:30] <heathkid> even our LSM has limits
[04:30] <heathkid> but I LOVE It
[04:30] <heathkid> the LSM (laser scanning microscope) can measure down to 1 micron
[04:30] <heathkid> but a lot of what I do is a LOT smaller than that
[04:30] <SpeedEvil> I've wondered if buying a dental x-ray tube from ebay, backing off a lot, and using a scintilator, with a camera focussed on it would work.
[04:31] <heathkid> it won't
[04:31] <heathkid> I tried
[04:31] <SpeedEvil> Wrong energy?
[04:31] <heathkid> I've got the X-Ray tube(s), scintalator crystals, and CCD cameras... just haven't found the right combination yet.
[04:32] <heathkid> and Kodak film is EXPENSIVE!
[04:32] <SpeedEvil> Do you get light out when you hit the scintillator?
[04:32] <heathkid> that and the chems for developing...
[04:32] <heathkid> nope
[04:32] <heathkid> not enough
[04:32] <heathkid> even at 170KeV
[04:32] <SpeedEvil> I was expecting I'd need to integrate for several seconds at least with the camera.
[04:32] <schofieldau> "I want to use it to inspect my balls."
[04:33] <heathkid> you need a photo multiplyer tube
[04:33] <SpeedEvil> If CCDs for astro work can pick up several photons - I don't think that's a hard requirement.
[04:33] <heathkid> try it
[04:33] <SpeedEvil> But it will need a long integration time.
[04:34] <heathkid> I want to build a live x-ray
[04:34] <SpeedEvil> Unfortunately, single-photon capable CCDs are epensive.
[04:34] <heathkid> have one at work
[04:34] <heathkid> but want one for my home lab
[04:34] <SpeedEvil> TI had some awesome ones that they never brought to mass market.
[04:34] <SpeedEvil> 'impactron'
[04:34] <SpeedEvil> solid state CCD amplified.
[04:34] <heathkid> sweet!
[04:35] <SpeedEvil> They had a wacky multiplication stage on the last row of the CCD
[04:35] <SpeedEvil> which had gain per 'bucket'
[04:35] <heathkid> wow
[04:36] <heathkid> I've got a SBIG ST-7... still not sensitive enough (yes, I know that's old tech now)

[04:36] <heathkid> but I've seen some of the new 3D live x-ray stuff...
[04:36] <heathkid> WOW
[04:37] <heathkid> the place I work is thinking about getting one... and if so, I might be able to get the "old" live x-ray as surplus
[04:37] <heathkid> at least that's my dream
[04:37] <SpeedEvil> They never became available on the TI site alas. And no hits on ebay for the last couple of years.
[04:38] <heathkid> let me talk to our SEM tech... he's built a desktop live x-ray
[04:38] <heathkid> I don't think my BGO crystals are sensitive enough
[04:38] <heathkid> and I'll find out what CCD chip he used
[04:38] <SpeedEvil> I was looking for at worst 10 min frame times.
[04:39] <SpeedEvil> Anything faster would be a bonus.
[04:39] <heathkid> 10 minutes per frame???
[04:39] <heathkid> damn!
[04:39] <heathkid> our OLD live x-ray does like 24fps
[04:39] <heathkid> and when I take an image I average 256 frames
[04:40] <heathkid> so I get a nice image
[04:40] <SpeedEvil> There are relatively inexpensive DSLR cameras second-hand - that can do really quite long exposures.
[04:40] <heathkid> I want live... not long exposure
[04:40] <SpeedEvil> Indeed.
[04:40] <SpeedEvil> Live is harder.

[09:32] <eroomde> and now i have a good job and am probably staying in one place for a while, i can throw a bit more time at it
[09:33] <daveake> When I moved house from Cov to Ipswich, a friend drove all my belongings there for me, and I did it on my bike
[09:33] <daveake> Legs like jelly at the end of that one
[09:33] <eroomde> can imagine!
[09:33] <eroomde> i've not done more than aqbout 90 miles in one single sitting
[09:33] <eroomde> you just run out of glycogen
[09:33] <daveake> Yep
[09:34] <daveake> Happened to me when I did Cov --> Dagenham to see my parents.
[09:34] <daveake> Got to the north circular and just stopped. Cold and wet and I could hardly stand
[09:34] <eroomde> i was told the solution is to put squash into your drinks bottle
[09:34] <eroomde> undiluted
[09:34] <daveake> Ran out of food so I hobbled into a newsagent for some sugar
[09:34] <eroomde> with a bit of salt for extra deliciousness
[09:35] <daveake> Couldn't even work my hands enough to open my wallet, so I handed it over for the guy to take the money
[09:35] <daveake> mmmSalt. I did have some of those salt-replacement packets but used them all up
[09:36] <daveake> Spent the next 5 mins in the phone box outside, trying to munch the food and warm up
[09:36] <eroomde> :)
[09:36] <daveake> Got back on the bike and I could feel my muscles slowly starting to work again
[09:36] <daveake> 10 mins later did the highest speed on the trip (though hill-assisted!)
[09:36] <eroomde> mmm
[09:37] <eroomde> there's an amazing hill between you and me daveake
[09:37] <eroomde> britwell hill
[09:37] <eroomde> it's like a mile long 1:4 descent
[09:37] <daveake> eek
[09:37] <eroomde> i got up to about 45mph there once
[09:37] <fsphil> nice
[09:37] <eroomde> it felt pretty hairy
[09:37] <daveake> Yep
[09:37] <eroomde> one misplaced pebble and i would have experienced what it would be like to be a bird for about 3 seconds
[09:37] <daveake> lol
[09:37] <eroomde> followed by the experience of what it is like to be a bunker buster
[09:38] <daveake> yep:(
[09:38] <fsphil> flying doesn't always work out for humans
[09:38] <daveake> In Cov I had the same accident twice, 2 weeks apart
[09:38] <number10> especially without a helmet
[09:38] <gonzo_> if god had intended us to fly, he would not have invented HAB
[09:38] <daveake> There is (or was) a steep hill into a bend where 2 roads merge into a 1-way street
[09:39] <daveake> The only safe way round is at the same speed as the merging traffic
[09:39] <daveake> So I hurl myself down the hill, then break to match the speed of the traffic near the bottom
[09:41] <daveake> But my back wheel had a dent, so the brake hit that, wheel locked, and before I knew what was happening I was sliding on the ground
[09:43] <daveake> What I should then have done was fix or replace the wheel, but I didn't, so 2 weeks later I did the same thing in the same place and landed on the same bit of ground bruising and scraping the same bits of my body

[09:43] <number10> head injuries on the first crash?
[09:44] <daveake> lol
[09:44] <number10> :)
[09:44] <daveake> Nope never hit my head :)
[09:44] <daveake> Well I don't recall ever ......
[09:44] <fsphil> next up on #ha's funniest home videos ... a cat that can sing!
[09:45] <fsphil> cycling is quite dangerous
[09:45] <fsphil> the amount of stupid I see even driving the 2 miles to work is unreal
[09:45] <fsphil> I'm not sure I'd feel safe cycling it at all
[09:45] <number10> chap in my office was knocked out a few weeks back - helmet smashed up but saved him
[09:46] <daveake> Ouch. A friend of mine got cut up by a car, which he braked to avoid, but didn't notice it was towing ....
[09:47] <daveake> Biggest problem is car drivers don't see you. You really have to cycle very defensively.
[09:47] <number10> make eye contact
[09:48] <daveake> Yep.
[09:48] <daveake> Though I even had a police car pull out in front of me after I thought I'd done just that
[09:49] <number10> foggy this morning had two people pull out in front of me while driving - one was nealy a collision - they both couldnt be bothered to clean moisture off side windows
[09:49] <number10> If I was on bike that would have been it
[09:49] <daveake> Worst one was car coming the other way then turning right across my path (and that of another cyclist just behind me). I was convinced we were going to hit, so I aimed for his front wheel in the hope that the bike would stop and I'd leap over the car. Managed to stop though
[09:50] <daveake> I was so shaken I couldn't bollock the driver. I left that to the other cyclist :)
[09:54] <number10> strange when you have a go at people - I sounded the hooter at these two this morning - and one off them wound the window down and gave me abuse
[09:55] <number10> so he does something wrong and its my fault - reminds me of the engineer, manager baloon joke
[09:56] <daveake> I had one a couple of weeks ago, going the wrong side of a small roundabout, and *he* made a sign to me as if *I* was wrong ...

[11:30] heathkid (~heathkid@unaffiliated/heathkid) joined #highaltitude.
[11:30] <navrac> it was what I thought - the RF22 library goes into idle state between tx and rx - and he has his idle state defined as xtal and pll off

[11:30] <daveake> +ahhhh
[11:31] daveake (daveake@daveake.plus.com) left #highaltitude.
[11:32] <navrac> if you use the rfm22 library and poke at the registers yourself and set the tx bit on and off - but leave the pll and xtal powered it is much cleaner. So I'll contact the library writer and point out the problem

[11:37] <navrac> no - there should just be a height limit on trees and emergency ladder points nearby

[11:52] <Upu> thanks
[11:52] <Laurenceb> as the pll has to be locked
[11:52] <Laurenceb> more likely the xtal?
[11:52] <navrac> it was a general discussion - but i found the cause - one of the libraries turned off the pll between tx and rx
[11:52] <navrac> and the xtal power too
[11:53] <navrac> if you use the simple library then if you change the registers manually its fine - drift<20hz

[12:26] <benoxley> We haven't been invited along to launch our payload :/
[12:26] <jonsowman> that's rubbish :( why?
[12:27] <LazyLeopard> Ho hum. Have you given the launch crew a step-by-step tick-every-box checklist?
[12:27] <LazyLeopard> ISTR the last time they left you off the launch crew it went slightly wrong...
[12:28] <jonsowman> Hmm yes i remember that too
[12:28] <daveake> oh dear
[12:28] <benoxley> Yes, I'd like to think that my uni supervisor should be capable and it was just the launch conditions last time
[12:29] <benoxley> It's being launch from the met-office site so there should be enough experienced people on-hand to help out

[12:46] <Randomskk> I really wouldn't bother
[12:46] <Randomskk> there's no problem with the ISM band stuff
[12:46] <Randomskk> 10mW is plenty
[12:46] <john_many_jars> but i'm not a citizen here... there is a limit to how much trouble i want
[12:46] <Randomskk> and the transmitter will have coverage over the entire UK, people will probably notice.

[12:47] <john_many_jars> random -> wow
[12:47] <john_many_jars> impressive

[15:40] <launchTZ> Hi, anyone who is from the UK?
[15:40] <daveake> one or two
[15:41] <launchTZ> I heard there is a special place you can launch from without a clearance from, where is that?
[15:42] <launchTZ> Excuse the second *from*
[15:42] <daveake> There are two sites, both in Cambs, which have permanent permission.
[15:42] <launchTZ> Thank you! any more specific location?
[15:43] <daveake> You'd need to speak to the people that have those permissions.
[15:43] <daveake> One is Churchill College Cambridge and I believe theirs is for any day; eother is further west and is weekends only. A permission-holder has to be present at the launch
[15:44] <daveake> Whereabouts are you?
[15:44] <launchTZ> How many permission holders are there? and how frequent are launches in this period?
[15:45] <daveake> For the Cambridge site; dunno. Other site - 1 person.
[15:45] <launchTZ> Thanks a ton daveake!
[15:45] <daveake> Frequency varies but a fair proportion of weekends there's a launch.

[16:21] <Hix> ok seen it on a number of boards and never knew what it was

[16:28] <eroomde> i put mounting holes on a board with that little material around their circumference one too
[16:28] <eroomde> and they cracked
[16:28] <eroomde> once*
[16:28] <jonsowman> how much stress were they under
[16:28] <jonsowman> ?
[16:29] <jonsowman> they're only there to hold the board in position on a chassis, not to take any force at all really
[16:29] <eroomde> not a huge amount
[16:29] <eroomde> just being tightened down with a nut
[16:29] <cuddykid> quick question: for a 2D array is it [column][row]?
[16:29] <zyp> what kind of 2D array?
[16:30] <zyp> it's [outer][inner], interpret that as you want
[16:30] <jonsowman> eroomde: well we shall see
[16:30] <jonsowman> from holding them and playing with them a bit I came to the conclusion that they should be OK

[17:48] <cuddykid> doh
[17:48] <daveake> Is this "array" a "table"?
[17:48] <cuddykid> effectively I guess - it's a 2D array

[18:01] <eroomde> the --leak-check=full is such a helpful flag for valgrind. it tells you exactly where you are messing up

[18:29] <eroomde> but if you want a recommendation from me, python is great and a free online book called 'Learn Python the Hard Way' is really excellent at introducing OO conceptually while learning python
[18:29] <NigeyS> can anyone explain why i have 5.5v coming from 3xaaa's? :|
[18:30] <daveake> Yes
[18:31] <daveake> O/C voltage from a fresh Lithium Energizer is about 1.84V
[18:31] <NigeyS> 2 @ 1.6 1 @ 1.7 .. doesnt equal 5.5 :|
[18:31] <daveake> 3 x 1.84 does
[18:32] <daveake> You measure each, and they don't add up to the measure total?
[18:32] <NigeyS> but individually the batteries have the above values
[18:32] <daveake> Your meter is broke
[18:32] <eroomde> you're measuring with a normal multimeter and nothing else attached to the batt?
[18:32] <NigeyS> yups, just got the MM on the lead from the battery holder.. very odd
[18:32] <Hix> eroomde, I need to know how the kitchen works :)
[18:33] <eroomde> :)
[18:33] <eroomde> I recommend learn python the hard way
[18:33] <eroomde> it's pedagogically complete as a first step
[18:34] <eroomde> ie it doesn't teach python and assume you just automatically know how to structure things in an OO way. it actually teaches you the OO way of thinking and style of programming too
[18:34] <Hix> ok I'll have a look at that
[18:34] <cuddykid> I've wrote so much code this afternoon :S

[23:28] <Graeme_SHARP> Hey All, Project SHARP at the University of Southampton are pleased to announce (Weather Permitting) our first launch this Sunday, 18th March 2012 at ~11am GMT. Launch site is Dover's Hill, Chipping Camden, Gloucestershire. More details are available at http://wp.me/P2fLw6-39 which will be updating continuously over next couple of days with things like the radio profiles.
[23:29] <daveake> So we have flights Friday, Saturday and Sunday :-)
[23:30] <Lunar_Lander> hi Graeme_SHARP
[23:31] <Graeme_SHARP> hi Lunar_Lander :-)
[23:32] <Lunar_Lander> let me guess
[23:32] <Lunar_Lander> wordpress :)?
[23:33] <Graeme_SHARP> Its quick, simple and easy and does the job :)
[23:35] <Lunar_Lander> yeah :)
[23:35] <NigeyS> graeme, how are tracking?

[23:37] <Lunar_Lander> OK let me take a guess at the Team Photo
[23:37] <Lunar_Lander> Graeme is the guy in the red jacket
[23:37] <Lunar_Lander> :)
[23:38] <Graeme_SHARP> NigeyS, it will be RTTY on 433MhZ, I just need to get the comms guy to confirm the finer details tomorrow.
[23:38] <NigeyS> ahh okies, do let us know, might be worth posting to the ukhas mailing list to :-)
[23:39] <Graeme_SHARP> Heh, Lunar, we've been concentrating on getting a functioning payload and updating the website when we have a chance :)
[23:39] <jonsowman> Graeme_SHARP: you are not planning to use the CUSF site then?
[23:40] <Lunar_Lander> yeah
[23:40] <Graeme_SHARP> And nope Lunar , that's Rich our code monkey (who is sitting next to me though)
[23:41] <Graeme_SHARP> NigeyS, already posted it, just waiting moderator confirmation.
[23:41] <NigeyS> :D
[23:41] <jonsowman> there are no emails awaiting moderation on the ukhas list
[23:42] <jcoxon> ping Randomskk
[23:42] <Randomskk> hi
[23:42] <jcoxon> what you up to on saturday?
[23:42] <Randomskk> nothing more urgent than sleep
[23:42] <Randomskk> (though I should say that sleep is fairly high on my priority list right now ;P)
[23:42] <jonsowman> and probably higher by saturday?
[23:42] <jcoxon> i've got to drop a regulator off
[23:42] <jcoxon> want one?
[23:42] Jasperw (~jasperw@2a01:348:82:0:223:5aff:fef5:cce) left irc: Quit: Leaving.
[23:42] <Randomskk> oh yes please
[23:42] <jcoxon> its nice and snazzy
[23:43] <Randomskk> I bet it is
[23:43] <jcoxon> what would you rather? early morn or late afternoon
[23:43] <jcoxon> ?
[23:43] <Graeme_SHARP> jonsowman, Nope I thought Sophie contacted you a couple of days ago saying the flight paths wern't to favourable and we really don't want to take a dip in the Sea, so we were going to be trying somewhere further West.
[23:43] <Lunar_Lander> xD Graeme_SHARP, OK
[23:43] <Randomskk> don't really mind but in the run of things probably late afternoon
[23:43] <jonsowman> Graeme_SHARP: we've had no contact from you at all
[23:43] <Lunar_Lander> Sophie is in the front row, leftmost
[23:43] <Lunar_Lander> :)
[23:43] <Randomskk> whatever's more convenient for you though
[23:44] <Randomskk> Graeme_SHARP: for what it's worth I'm going to be in Cambridge all of next week if you want to launch later than Sunday
[23:44] <jcoxon> Randomskk, don't want to come launching in suffolk on sunday?

[23:45] <jcoxon> oops
[23:45] <Randomskk> ooh
[23:45] <jonsowman> Graeme_SHARP: in future we would appreciate more notice of a launch cancellation, we would not have known had it not been for me watching this IRC channel
[23:45] <Randomskk> could be tempted
[23:45] <Graeme_SHARP> and hmmm, I sent it to UKHAS@googlegroups.com, I guessing that is the right thing to do?
[23:45] <Randomskk> you know, we have this really nice mass flow meter here jcoxon
[23:45] <Randomskk> and it's in this pretty portable box...
[23:46] Action: NigeyS hides the flow meter
[23:46] <Graeme_SHARP> Sorry Jon, I was under the impression Sophie was in contact with you earlier in the week (around Monday or Tuesday)
[23:46] <jonsowman> no problems Graeme_SHARP
[23:46] <jcoxon> Randomskk, ->PM
[23:46] <jonsowman> that's the correct email address for the ukhas list
[23:46] <jonsowman> but there are no new emails awaiting moderation
[23:46] <jonsowman> perhaps send it again
