[00:00] <Randomskk> omg whaat
[00:00] <Darkside> ok that predictor is a bit annoying
[00:00] <Darkside> i prefer to set the ascent/descent rates
[00:01] <Darkside> Train equivalent sphere diameter
[00:01] <Darkside> wat
[00:01] Action: Darkside goes back to the CUSF predictor
[00:02] <cuddykid> neat, but yeah, prefer cusf
[00:02] <cuddykid> what I do like is the ability to select launch site from map - but that is minor
[00:02] <Randomskk> has this been announced anywhere?
[00:02] <cuddykid> first I've seen of it
[00:02] <Darkside> cuddykid: you can do that on teh cusf predictor
[00:03] <cuddykid> Darkside: oh true, you can - forgot as I haven't used it in a while
[00:03] <Darkside> anyway, a version of that predictor where i can set the ascent and descent rates would be nice
[00:03] <Darkside> because we can get those dead right 9 times out of 10 now
[00:04] <cuddykid> yep
[00:05] <Darkside> anyway, i'm off to go hunt down a radio fox

[09:51] <HixWork> can anyone point me in the direction of the free online VM people on here were recommending, serched logs but cant trawl it up
[09:52] <HixWork> wondered if the hourly would work on it
[09:52] <costyn> HixWork: another one?
[09:52] <fsphil> VM software?
[09:52] <fsphil> I like VirtualBox
[09:52] <costyn> oh you mean to run the vm
[09:52] <costyn> yea VirtualBox FTW
[09:52] <costyn> HixWork: running the CentOS VM on that at the moment
[09:54] <daveake> +1 for VirtualBox
[09:57] <HixWork> thats the cookie ta
[09:58] <HixWork> port 9090 is blocke dso no NOAA data for me
[10:03] <costyn> bah
[10:04] <fsphil> O2 are far too filter happy
[10:05] <HixWork> apparently they have all outgoing ports open apart from one, not 9090, cant remember which on is is though
[10:05] <HixWork> think its the shat Thompson router
[10:05] <HixWork> which apparently you can ssh into
[10:06] <HixWork> but I wouldn't know what i was doing so would prob bork it
[10:06] <costyn> heh
[10:06] <HixWork> VirtualBox i reckon it is then....
[10:06] <costyn> would be strange if only that port were blocked?
[10:07] <costyn> HixWork: port 25 is often blocked outgoing
[10:07] <costyn> to prevent spam and such
[10:07] <HixWork> that's be the one, thought it was but kept schtum in case wrong
[10:07] <costyn> schtum?

[10:11] <costyn> never heard that word before :)
[10:12] <HixWork> ahh, no virtualbox isn't the thing i was thinking of, there's an online free vm system
[10:15] <costyn> that would be weird if it was free
[10:15] <costyn> I mean, lots of companies earn money by letting people run VMs
[10:17] <zyp> HixWork, you mean VPS providers?
[10:17] <HixWork> somebody was using it as an IRC logger
[10:17] <HixWork> yeah think so zyp
[10:21] <griffonbot> Received email: RG-lz1dev "[UKHAS] Re: Can we use APRS in your country?"
[10:22] <fsphil> ah I think I remember that HixWork
[10:23] <staylo> http://www.lowendbox.com/ is a list of cheap VPS providers, none are free though.
[10:23] <fsphil> linode isn't free but they're great
[10:24] <HixWork> hmm, i'm looking into getting into the router to open 9090, see howe it goes, got a spare if i bork it
[10:25] <HixWork> fsphil, it was june/july last year but i can find it
[10:25] <HixWork> oh, btw how was cheese on toast with HP?
[10:26] <eroomde> like you need to ask
[10:26] <fsphil> rather lovely
[10:26] <HixWork> eroomde, he hadn't tried it.....
[10:27] <eroomde> quelle horreur
[10:27] <HixWork> dunno how not but he hadn't
[10:27] <HixWork> Oui
[10:27] <fsphil> it has been done now, and the result is known
[10:27] <HixWork> :D
[10:27] <HixWork> all in the name of science
[10:28] <eroomde> 100% satisfaction guaranteed
[10:29] <russss> interesting
[10:29] <costyn> haven't had a welsh rarebit in a looooooooooong time

[10:33] <HixWork> th ebread from the one at spitalfields is ftw
[10:33] <eroomde> yes!
[10:33] <eroomde> infact they now make the bread at borough
[10:33] <eroomde> they outgrew spitalfields
[10:33] <eroomde> they're right next to the borough Neal's Yard
[10:33] <HixWork> not surprised
[10:34] <eroomde> it is an expensive but necessary detour
[10:34] <HixWork> i'll check out next time i'm that way
[10:34] <HixWork> yup
[10:34] <HixWork> can't beat good bread
[10:34] <HixWork> and sausages and bacon
[10:34] <HixWork> and eggs
[10:34] <HixWork> all together
[10:34] <eroomde> especially if you go to the south bank under the premise of cultural pursuits
[10:34] <HixWork> are they served in units of half or pint
[10:35] <eroomde> are what?
[10:35] <HixWork> cultural pursuits
[10:36] <eroomde> if only
[10:36] <eroomde> there's a really nice bar in the festival hall on the 2nd or 3 or whatever floor looking out onto the thames with a little balcony. really nice, never busy
[10:36] <eroomde> but these places seem to think £5/pint is acceptable
[10:36] <eroomde> probably explains why they're never busy
[10:37] <eroomde> $7/pint minimum in the US too, poor buggers

[14:35] <sjohn> Hello, i have a dongle dvb-t and wanted to know what the impedance is?
[14:35] <HixWork> :D
[14:35] <Brace> eroomde: step away from latex
[14:35] <eroomde> I love latex
[14:35] <Brace> it's damaging to your sanity
[14:35] <Laurenceb> sjohn: debatable
[14:35] <Laurenceb> 50 or 70ohm
[14:35] <eroomde> i am v surprised it's not already on the machine
[14:36] <HixWork> bearing to dest for tracker?
[14:36] <Laurenceb> depending who you ask
[14:36] <HixWork> and dist to dest
[14:36] <eroomde> but this machine is a rebuild as it died just after christmas so i never got round to it before dissappearing away for the last 5 weeks
[14:37] <sjohn> i wanted to connect an Antenna, so i was thinking should the terminal impedance match the transmitting antennas terminal impedance
[14:37] <Brace> I have a oneliner knocking around which installs everything I want on a machine
[14:37] <sjohn> i was thinking should i connect a 50 ohm antenna
[14:37] <Brace> as I'm hosing them quite a lot, saves me remembering what I need installed
[14:38] <mattbrejza> sjohn: even if it is 70ohm the mismatch loss is like .2dB or something
[14:38] <eroomde> yeah i keep thinking i should do that
[14:38] <eroomde> just one script to get my machine ready automatically
[14:38] <fsphil> eroomde: what's the rule on RC near the ground
[14:38] <eroomde> + pulling my dotfiles from github etc
[14:38] <fsphil> guessing none at all
[14:38] <eroomde> i think you have to be below 400ft AGL
[14:38] <eroomde> then you're in safely rc territory
[14:38] <eroomde> and have LoS
[14:39] <Brace> eroomde: if you're doing lots of machine management, then ansible is very good
[14:39] <sjohn> how about the antenna to connect to the ntx2
[14:39] <eroomde> but i am going to specify it must be completely autonomous to qualify
[14:39] <fsphil> thought so
[14:39] <mattbrejza> ntx2 is 50ohm
[14:39] <HixWork> heh
[14:39] <eroomde> so you can't just pop a big chute out of a mortar to snatch it out the air if it's going in a straight line overhead but still at 500ft
[14:40] <eroomde> well you can, but it would have to be autonomous
[14:40] <Laurenceb> *cough*
[14:40] <Laurenceb> ROGALLO
[14:41] <daveake> nasty cold you've got there
[14:41] <fsphil> it's gollum
[14:41] <Laurenceb> my rogallo
[14:41] <costyn> my precioussssss
[14:41] <Laurenceb> ...precious
[14:42] <sjohn> Apologies Im sort of a beginner with all this, So a 50ohm TX antenna and a 70hm RX antenna can communicate
[14:43] <HixWork> I don't think so sjohn think impedance has to be matched
[14:43] <gonzo_> you have a 50R ant on the transmitter and 70r on the receiver?
[14:43] <mfa298> sjohn: ideally you want the impedance to match within a system ie the transmitter and the antenna connected to it.
[14:43] <daveake> It's /best/ to match transmitter inpedance with that of the aerial it's connected to. Same goes at the rx end.
[14:44] <daveake> But the rx end doesn't care what impedances are at the tx end
[14:44] <HixWork> eroomde, can my payload go in an actionman?
[14:45] <daveake> No, has to be a Barbie doll
[14:45] <sjohn> i see, so for the dongle i can connect a 50-70 ohm antenna at the receiver
[14:45] <fsphil> Action Barbie
[14:45] <HixWork> oh, but she'll look a twat in a big bergen
[14:45] <daveake> Habby Barbie
[14:45] <zyp> sjohn, you should match antenna, cable and receiver
[14:45] <fsphil> Felix Barbiegarten
[14:46] <gonzo_> a mismatch of 50r and 70R will hardly be noticeable in reality
[14:47] <daveake> The 1/4 wave aerials we usually build are 70-ish I think anyway. They work.
[14:48] <gonzo_> the impredence of the input of a dongle is unlikley to actually be 70R anyway.
[14:49] <eroomde> action persons are acceptable
[14:49] <fsphil> points deducted for the colour pink

[16:41] <HixWork> eroomde, did you get from .NL warehouse?
[16:51] <eroomde> yep
[16:52] <HixWork> hmmm, shouldn't be too far behind you hopefully. no confirmation yet tho
[16:53] <HixWork> I reckon one good servo should do the trick
[16:53] <eroomde> yes same
[16:53] <eroomde> assuming a load of stuff about how it flies at different pressures
[16:54] <mattbrejza> craag: i *think* its fixed
[16:54] <HixWork> I dont really think it's a massive issue higher up, in fact prob better out of hte way up there, just a drogue
[16:54] <eroomde> but breaks and AoA control might be fun for some cleverer stuff
[16:54] <eroomde> like landing flare :)
[16:54] <mattbrejza> but i wont be able to do a 600 build by doubling the sample rate, 16000 isnt a standard sample rate
[16:55] <HixWork> hmmm bugger yeah, 1 servo cant brake it
[16:55] <eroomde> i have put a ground speed constraint at landing
[16:55] <eroomde> so you can't just plummet into a greenhouse or whatever
[16:55] <HixWork> <5m/s no?
[16:56] <daveake> It'll be more than that sideways
[16:56] <eroomde> or pro cutaway of payload when you happen to be somewhere within the landing circle
[16:56] <eroomde> pyro*
[16:56] <daveake> pro also
[16:56] <eroomde> 5m/s vertical
[16:56] <eroomde> 10m/s ground speed
[16:56] <eroomde> your airseed can obviously be higher. there might be some advantages to having it higher too
[16:56] <eroomde> i think 10m/s is quite generous really :)
[16:56] <HixWork> 22.3693629 mph
[16:57] <HixWork> i'd say fair
[16:57] <eroomde> the ideal would be landing into wind and flaring almost to a complete stand still in the last few meters
[16:57] <HixWork> that's just being flash
[16:57] <eroomde> yep
[16:57] <HixWork> what next smokes on it too
[16:57] <HixWork> and a walk away from the DZ
[16:57] <eroomde> but it's all with half an eye on a future generally applicable payload landing system that is nice and safe
[16:58] <HixWork> no, its a competition ;p
[16:59] <HixWork> looking at things that used taht sized foil for RC they were ~1800g :/

[17:00] <eroomde> sure but i'm from back in the day when that was lightweight for a payload
[17:00] <eroomde> the last thing i launched was about 15kg
[17:00] <eroomde> and it's a limit not a recommendation anyway :)

[19:01] <mfa298> I'm not sure it's something in Chris# vm image, although something in your setup seems to be stopping the vm talking out.
[19:02] <mfa298> wireshark is a tool for capturing traffic on the network, very useful if you understand what it's telling you.
[19:02] <Hix> only seems to be port 9090 on the vm though pings were going through
[19:02] <Hix> i'll have a look at it but it sounds like its a bit too high level for me
[19:02] <mfa298> didn't you say your router was saying something about blocking it because it thought there was an attack ?
[19:03] <DanielRichman> Hix: if you've been given a VM image, and your error is "Bad hostname 'nomads.ncep.noaa.gov'" you may need to tweak the DNS settings
[19:03] <mfa298> I wouldn't worry about it for this. I don't think it's going to help you much

[19:03] <mfa298> DanielRichman: we checked that yesterday and it seemed to be ok.
[19:03] <DanielRichman> maybe /etc/resolv.conf but I can't remember if non debian based things used that (and that prompt doesn't look debian)

[19:56] <DanielRichman> k well
[19:56] <mfa298> two things I can see being worth a try
[19:56] <DanielRichman> from what you just pasted it does look like DNS trouble
[19:56] <mfa298> 1) reboot to clear out caches
[19:57] <mfa298> 2) set /etc/resolv.conf to use 8.8.8.8
[19:57] <DanielRichman> don't think there are any relevant caches
[19:57] <DanielRichman> I support 2
[19:57] <mfa298> unfortunately I think for #2 Network Manager will break it after a while/reboot
[19:57] <Hix> 1) is underway
[19:57] <DanielRichman> mkay. So, is this CentOS?
[19:57] <Hix> 2) has to wait
[19:57] <Hix> yup
[19:57] <mfa298> I think linux does some caching of dns stuff and there's no easy way to clear ir.
[19:58] <mfa298> although a negative response really should have times out by now
[19:58] <Hix> there's not a flushdns command equiv than?
[19:59] <mfa298> not that I've found for the core libraries,
[19:59] <mfa298> the name caching daemon can be flushed but I don't think that runs by default it most setups
[19:59] <Hix> rebooted and still cant locate a dataset for the requested time
[19:59] <DanielRichman> I don't think it caches. 2 calls to gethostbyname() results in 2 DNS queries on my box
[20:00] <DanielRichman> *2 DNS queries over the wire
[20:00] <DanielRichman> caching will be done by a caching DNS server. You could in theory run one on localhost, but I don't think anyone bothers
[20:01] <mfa298> I've never fully understood what it does, I've seen appear to cache stuff in the past although usually I think it's only for a few minutes.
[20:01] <Hix> so set resolv.conf to use 8.8.8.8 as name server?
[20:01] <mfa298> Hix: yes
[20:01] <DanielRichman> yes, If that works we can see about making it persistent
[20:01] <Hix> ok trying it now
[20:02] <mfa298> you should just need to edit resolv.conf and it will change immediately
[20:02] <Hix> making what persistent?
[20:03] <Hix> and what is 8.8.8.8?
[20:03] <mfa298> I think /etc/resolv.conf will probably get overwritten when NetworkManager restarts / renews it's dhcp lease
[20:03] <Hix> is it an úber dns nameserver?
[20:03] <mfa298> it's an open recursive dns server
[20:03] <Hix> fetch .... is taking quite a bit longer than it has ever before
[20:03] <mfa298> I've forgotten who runs it
[20:04] <mfa298> if you run "ls -ltr /opt/landing-prediction-data/logs/"
[20:05] <mfa298> and then " tail -f /opt/landing-prediction-data/logs/<filename>"
[20:05] <mfa298> where filename is the last entry in the ls you should see it doing stuff
[20:05] <mfa298> filename will probably be something like "fetchdatalog-2013.02.21-20:04:00"
[20:07] <Hix> its still running fetch.... will that not itnerrupt it?
[20:07] <mfa298> you'll want another window for that

[20:11] <Hix> so 8.8.8.8 is handling everything DNS from now on then?
[20:11] <mfa298> currently
[20:12] <mfa298> now to find out how to stop NetworkManager changing it back.

[20:12] <mfa298> Unfortunately I don't tend to use NetworkManager so I'm not sure what to do off hand
[20:13] <Hix> is this a dns issue with the router then
[20:13] <mfa298> fsphil: that could be a sensible option
[20:13] <mfa298> Hix: it seems like it
[20:14] <Hix> ok, I found a manual for telnet into it and I'm sure there was a flush dns page somewhere

[20:21] <Hix> up to sunday so far
[20:21] <DanielRichman> if it's a £20 adsl router just turn it off and on again...
[20:21] <mfa298> 7 days I think
[20:21] <Hix> oh, could be a while then :)
[20:21] <mfa298> I don't think either of the Thompson routers I had lasted more than a year
[20:22] <fsphil> the usual suspect is the psu
[20:22] <fsphil> linksys routers always came with short lived psus
[20:23] <mfa298> I've stopped buying cheap routers, although I've got to decide what to do as it looks like the exchange can now do >8mbps but my router wont do more.

[20:24] <Hix> this one is about 3 years old
[20:24] <fsphil> my wrt54gl only handles about 20mbit/s
[20:25] <Hix> ah so from the logs I can tell when this job kicked off and i can get info on the last file to see how long the job ran for?
[20:25] <mfa298> my current one I got 2nd hand on ebay a couple of years ago as an upgrade from the previous one I probably bought 10 years ago (and as far as I know still works)
[20:26] <mfa298> Hix: you can work that out from the filename and modification time.
[20:26] <Hix> I'd like a router that I can manually assign an IP to every device on the network frm the router
[20:26] <mfa298> my last one took around 15minutes to run
[20:26] <mfa298> at 18:30

[20:27] <DanielRichman> you might be able to adjust the dhcp range on the router
[20:27] <DanielRichman> like, set it to 192.168.0.100-200 instead
[20:28] <Hix> yeah can do that but it'd be nice to set everyting to my choice
[20:28] <DanielRichman> then you can statically assign ones in 1-100 by hand on each pc
[20:28] <Hix> ipads phones etc are just making a mess
[20:29] <Hix> ahh get you dhcp for other items, what i want, in my reserved range
[20:29] <Hix> fetch kicked off at 20:02 and is up to mon 18:00 thus far
[20:29] <Hix> so connection has to have a bearing on it
[20:29] <mfa298> Hix: you might be able to setup static ip's on the router via its telnet interface although my memory of thompsons telnet is that doing anything that way is a pain (although last time I did that was probably 10 years ago)
[20:30] <Hix> i did look at that earlier - the manual is shite

[21:20] <chrisstubbs> right ive got it all plugged together, and sending data (i think)

[21:23] <chrisstubbs> ah, i think thats copied straight from UKHAS
[21:23] <chrisstubbs> RV hasnt changed anything in fldigi, still no decode
[21:24] <chrisstubbs> i will swap them over in the source

[21:25] <daveake> Have you got dl-fldigi set to 8 bits no parity?
[21:26] <chrisstubbs> ah no i have not, will change both now :)
[21:27] <chrisstubbs> 1 stop bit?
[21:27] <daveake> doesn't matter
[21:27] <daveake> I'm told fldigi ignores that
[21:28] <daveake> If you send 2 (which you are) then the receiver will work whether it's set to 1 or 2

[21:35] <daveake> it does

[21:47] <jcoxon> if only
[21:48] <jcoxon> you could write some code to do that
[21:48] <chrisstubbs> oh is that not the case
[21:48] <jcoxon> as it has an onboard temp
[21:48] <jcoxon> but it doesn't do it automatically
[21:48] <chrisstubbs> i saw on the datasheet it had a built in thermometer

[22:04] <Upu> I don't think it was me who helped :)
[22:04] <Upu> its not too hard
[22:04] <Upu> just use flex
[22:04] <Upu> flux
[22:04] <Upu> small tip
[22:04] <Upu> I know its not recommended but start with a non GND pad
[22:05] <chrisstubbs> what to tack it in place?
[22:05] <Upu> the GND pads suck too much heat away to its best to tack it in place with another pad first
[22:05] <Upu> yep
[22:05] <chrisstubbs> ah ok, i just start with a corner tbh
[22:05] <Upu> also watch you don't over do the solder or it can "jump" up between the PCB and the metal shield
[22:05] <Upu> corners are GND
[22:05] <Upu> :)
[22:05] <chrisstubbs> aha okay
[22:05] <Upu> personally I start with bottom left 1 in
[22:06] <Upu> spin it round do the antenna GND (3 in) which is the hardest one
[22:06] <chrisstubbs> just tin the pad, hold it in place, then heat the pad until it sticks on?
[22:06] <Upu> after that the rest are easy just touch the PCB pad apply a little solder and it should wick up
[22:06] <Upu> no don't put the solder on the pad first
[22:06] <Upu> or it will raise the chip up
[22:06] <chrisstubbs> just for the corner tack i mean
[22:07] <Upu> just hold the iron on the pad not touching the GPS
[22:07] <Upu> ease some solder in and it should wick up
[22:07] <Upu> make sure the first one is right or you have zero chance of getting it off
[22:07] <chrisstubbs> sounds like im going to need a third hand to hold the thing!
[22:07] <chrisstubbs> ok cheers, that should save me from screwing it up too badly
[22:08] <Upu> and if you get stuck stop. I can get them off and fix them but if you knackered it can't help :)

[22:12] <Upu> hey Lunar
[22:12] <Upu> if it is five shoot
[22:13] <arko> My favorite was someone who bought a kit, sprinkled on all the components and just soldered them to random pads
[22:13] <Upu> and do yourself a favour
[22:13] <chrisstubbs> any leaded reccomendations?
[22:13] <Upu> used leaded
[22:13] <Upu> 0.3mm leaded
[22:13] <arko> Then asked whybit didnt work
[22:13] <Upu> lol
[22:13] <chrisstubbs> cheers, ebay time :)
[22:13] <arko> Upu: flux solves problems man
[22:14] <arko> That stuff is great

[22:15] <chrisstubbs> recently invested in this iron: http://www.flickr.com/photos/68579973@N02/8496391274/ seems awesome so far, only like £35 too
[22:15] <Upu> that looks nice :)
[22:15] <arko> Upu lol exactly that
[22:16] <chrisstubbs> flexi lead is a dream compared to mains ones
[22:16] <arko> Nice station
[22:17] <chrisstubbs> i would have gone for a weller, but we have OK international (chinese brand) ones at work and they seem amazing
[22:17] <chrisstubbs> so thought i would go for a cheapish one
[22:17] <arko> They also make heatguns right?
[22:18] <chrisstubbs> OKI, i think so
[22:18] <arko> Brand looks familiar in a chinese wY
[22:18] <chrisstubbs> there are a few heatgun rework stations there but not paid attention the the brand, will look tommorow
[22:19] <arko> Heatguns are great
[22:19] <chrisstubbs> True, sent a laptop off to have the GPU reballed, came back and broke within a few weeks, blast on the heat gun and its been going again for like 6 months

[22:21] <chrisstubbs> ish is what puts me off doing it for money, knowing the state of people on gumtree some angry chav will smash your house up with his broken xbox
[22:21] <arko> Yeah, most of my friends had redrings around the samr time, i did a few for free until it got out of hand

[22:23] <arko> I think its by MG chemicals
[22:23] <arko> Or some name like thag
[22:23] <arko> Its not watery
[22:23] <arko> Until heated
[22:23] <arko> Then its everywhere

[22:25] <chrisstubbs> im using acetone at home beacuse thats all i have
[22:26] <chrisstubbs> not great but cleans it up a bit
[22:26] <arko> Heh, yeah
[22:26] <arko> Hot water before and after acetone is nice too
[22:26] <arko> As long asbyou dont have sensors
[22:26] <arko> And you dry it
[22:26] <chrisstubbs> whys that?
[22:27] <arko> I ruined a baro sensor once by pouring water on the pcb to clean it
[22:27] <arko> Hot water that is

[22:28] <arko> Lol
[22:28] <chrisstubbs> probably not the best way, but its what my dad taught me

[22:30] <chrisstubbs> the tub is just chinese ebay stuff, works pretty well on thru hole but is messy

[22:44] <arko> I want to do a 50g flight with this stuff
[22:44] <chrisstubbs> got a little experience with the hardware
[22:44] <daveake> Someone else used that last year
[22:44] <arko> Maybe get a quick payload ready this weekend who knows
[22:44] <daveake> Didn't go well
[22:44] <chrisstubbs> well a fair bit, mostly graphical stuff. its pretty good to work with but expensive
[22:44] <chrisstubbs> ahh man
[22:45] <chrisstubbs> yeah its not exactly reliable. our college were testing the educational version for microsoft reaserch and we fried about 3 mainboard just from static...
[22:45] <daveake> Hah

[22:49] <Darkside> uh oh
[22:50] <chrisstubbs> yeah i can imagine timing on the gadgeteer was difficult. i would end up using a atmega as a buffer to actually send teh RTTY

[23:12] <Randomskk> it depends
[23:12] <mfa298> the people doing the launch were from the US and I think they had to do various last minute changes
[23:13] <fsphil> ah, yes 433.650 is fine with a 10% duty limit
[23:13] <mattbrejza> 433.65 might be but 0dB power limit
[23:13] <fsphil> and yes 10mw
[23:13] <mattbrejza> dBm rather
[23:13] <Randomskk> and might not be OK airborne
[23:13] <fsphil> it is
[23:13] <fsphil> just checked the sheet

[23:13] <fsphil> 433.05 - 434.79
[23:14] <fsphil> aprs would certainly work fine with 10% duty limit

[23:40] <nigelvh> Thermite
[23:40] <jonsowman> or that
[23:40] <lz1dev> net use hammer
[23:41] <jonsowman> ..
[23:41] <lz1dev> wait thats windoze
[23:41] <fsphil> you can't use a hammer in windows, they'll break
[23:41] <mfa298> I think there are some net * command on linux now (thanks to samba)
[23:41] <nigelvh> http://unitednuclear.com/index.php?main_page=product_info&cPath=16_17_69&products_id=208
[23:42] <lz1dev> Quantity Restriction No
[23:42] <lz1dev> cool
[23:42] <jonsowman> Randomskk: ^ for Quasar?
[23:42] <nigelvh> Though I'm sure you could buy the raw ingredients much cheaper and make your own than their prices.
[23:42] <jonsowman> that'll make the sodding thing ignite
[23:42] <jonsowman> :D
[23:43] <jonsowman> oh they sell ignition mixture too
[23:43] <jonsowman> how handy
[23:43] <Randomskk> haha yes excellent
[23:44] <lz1dev> i read that in an evil voice
[23:44] <nigelvh> Or, perhaps you need some Uranium Ore.. http://unitednuclear.com/index.php?main_page=index&cPath=2_4
[23:44] <jonsowman> no I don't think the porters would enjoy that
[23:44] <nigelvh> Or a death laser? http://unitednuclear.com/index.php?main_page=product_info&cPath=27_82&products_id=534
[23:45] <lz1dev> so what else do we need for that death star?
[23:45] <jonsowman> I'll have two
[23:46] <nigelvh> Or perhaps a homebuilt x-ray machine is your cup of tea: http://unitednuclear.com/index.php?main_page=product_info&cPath=2_13&products_id=592
[23:46] <nigelvh> In summary, this place is awesome and ludicrous.
[23:47] <lz1dev> just to mix the suggar cubes with the ore
[23:47] <lz1dev> just dont*
[23:49] <nigelvh> I also like their warning on their larger neodymium magnets, "They are strong enough to break arm bones and crush hands in the blink of an eye."
[23:51] <nigelvh> That site always makes me want to become a mad scientist.
[23:51] <nigelvh> Soooo much cool evil stuff to do.
