[01:13] <Randomskk> hmmm
[01:13] <Randomskk> I have a radio
[01:13] <Randomskk> it may be transmitting
[01:13] <Randomskk> if so I have no clue what frequency
[01:13] <Randomskk> it could be, technically, anything from 75MHz to 1GHz depending on radio setup.
[01:13] <Randomskk> its output network is tuned for approximately 434MHz
[01:13] <Randomskk> it will be transmitting a single tone, or in FM a constant silencing
[01:13] <Randomskk> this is gonna be so much fun to find
[01:14] <SpeedEvil> I would let you borrow my frequency meter - but ...
[01:15] <Randomskk> I don't even know for sure that it's transmitting

[01:50] <Randomskk> I found a tone on 432MHz
[01:51] <Randomskk> but it appears to be... a harmonic of one of the ARM's internal clocks, and nothing to do with my radio
[01:53] <SpeedEvil> :)
[01:55] <Darkside> Randomskk: ARM?
[01:55] <Randomskk> the microprocessor I'm using
[01:56] <Darkside> telemetry payload?
[01:56] <Randomskk> I can't even tell if the radio is transmitting, let alone what frequency :|
[01:56] <Randomskk> Darkside: just testing a radio
[01:56] <Darkside> ok
[01:56] <Randomskk> ARM is my nearest/easiest dev board :P
[01:58] <Darkside> heh ok
[01:58] <Darkside> what radio?
[01:58] <Randomskk> ADF7012
[01:58] <Randomskk> it's an analog devices radio on a chip thing
[01:59] <Darkside> hmm ok
[02:00] <Darkside> 75MHz to 1GHz!
[02:00] <Randomskk> yea
[02:00] <Randomskk> it has a fairly wide frequency range
[02:01] <Darkside> wow
[02:01] <Darkside> do you have a dev-board or something?
[02:01] <Randomskk> not really, I made up a circuit board for it
[02:02] <Darkside> mm ok

[02:04] <Darkside> cool
[02:04] <Darkside> i'm currently looking at this: http://www.mirics.com/fm_files/Mirics_MSi002_June10.pdf
[02:04] <Randomskk> oh, nice
[02:04] <Randomskk> what for?
[02:05] <Darkside> wideband HF SDR
[02:05] <Randomskk> sweet
[02:05] <Darkside> ideally to be used in a remote RX site, for analysis of DRM signals
[02:05] <Darkside> that chip -> Blackfin DSP -> small HF transmitter
[02:05] <Darkside> needs to be a DSP, because i'm going to need to do 4096-point FFTs
[02:06] <Darkside> its the only way you can resolve the DRM frequency references, and do frequency offset correction
[02:06] <Darkside> i was considering using an ARM, but decided to go all out and use a Blackfin and run uClinux on it >_>
[02:06] <Randomskk> sounds pretty cool

[02:57] <SpeedEvil> Darkside: neat!
[02:57] <SpeedEvil> however - you get a _Lot_ wider than 96 nowadays
[02:57] <Darkside> well yes
[02:57] <SpeedEvil> It'd probably mean going FPGA to do a 100MHz SDR though
[02:58] <Darkside> yeah i don't want to do that
[02:58] <SpeedEvil> And I'm not sure about how the filters'd work
[02:58] <Darkside> mm
[02:58] <Darkside> i know there ate 192KHz sample rate audio codecs out there
[02:58] <SpeedEvil> 50MHz I mean
[02:58] <SpeedEvil> (16 bit 100MHz ADCs are redily available now)
[02:58] <SpeedEvil> Insane
[02:58] <Darkside> yeah we have them
[02:59] <Darkside> theres another receiver i've been working with that has a 2x 16-bit 105MSPS ADCs in it
[02:59] <SpeedEvil> :)
[02:59] <Darkside> it uses a Spartan 3 FPGA to take the data and send it to the PC
[02:59] <SpeedEvil> Not the only way. You can do GPS referencing
[02:59] <SpeedEvil> (frequency)
[02:59] <Darkside> eh?
[03:00] <SpeedEvil> Sorry - (03:06:06 AM) Darkside: its the only way you can resolve the DRM frequency references, and do frequency offset correction
[03:00] <Darkside> no
[03:00] <Darkside> freq offset correction is to match the receiver with teh transmitter
[03:00] <SpeedEvil> Not fully awake ATM
[03:01] <Darkside> the transmitter isn't necessarily locked to some kind of standard
[03:01] <SpeedEvil> I see
[03:01] <SpeedEvil> DRM is what - OFDM?
[03:01] <Darkside> yep
[03:01] <SpeedEvil> Smilar to DAB I guess
[03:01] <Darkside> ~200 sub-carriers for the mode i'm looking at
[03:01] <Darkside> 37 baud symbol rate, including guard band
[03:02] <SpeedEvil> Oh - guess not quite
[03:02] <SpeedEvil> DAB is much wider
[03:02] <Darkside> yeah
[03:02] <Darkside> its a similar idea to DAB though
[03:02] <SpeedEvil> Each mux is somewhere like a megabit
[03:02] <Darkside> but in only 10KHz bandwidth
[03:02] <Darkside> DAB = 1.536MHz wide
[03:02] <SpeedEvil> ah
[03:02] Action: SpeedEvil is annoyed that you can't get DAB USB recievers
[03:03] <SpeedEvil> At all.
[03:03] <Darkside> eh?
[03:03] <SpeedEvil> (at least in dongle form)
[03:03] <Darkside> DAB or DAB+
[03:03] <Darkside> i have a DAB usb dongle
[03:03] <SpeedEvil> DAB - I don't see the UK moving to DAB+ in the near future
[03:03] <Darkside> well, it claims to be a DAB reciever, i haven't had a chance go try it out
[03:03] <SpeedEvil> The Psion WAvewhatrever?
[03:03] <Darkside> no
[03:03] <Darkside> EzCap
[03:03] <SpeedEvil> Oh.
[03:04] <SpeedEvil> I think I must have searched last time and not found it just before release
[03:04] <SpeedEvil> I have one of these
[03:04] <SpeedEvil> http://www.amazon.co.uk/Pure-Rechargeable-Weatherproof-Digital-Internet/dp/B003WOL500/ref=sr_1_1?ie=UTF8&qid=1298920585&sr=8-1
[03:04] <SpeedEvil> Though - the earlier one
[03:04] <SpeedEvil> that's just DAB
[03:05] <Darkside> mm
[03:05] <SpeedEvil> It's a lovely package.
[03:05] <Darkside> TBH i'm not that interested in DAB
[03:05] <SpeedEvil> Mechanically
[03:05] <Darkside> i just use net radio mostly :P
[03:05] <Darkside> and DAB is too wideband to be able to demodulate in software
[03:05] <Darkside> well, easily anyway
[03:05] <SpeedEvil> Yeah - I looked at it - it gets unpleasantly large.
[03:05] <SpeedEvil> GPS is unpleasant enough.
[03:05] <Darkside> heh
[03:06] <Darkside> DRM is doable, and ahs been done
[03:06] <SpeedEvil> And GPS is lots simpler.
[03:06] <Darkside> what i'm working on only requires everything up to the channel estimation point
[03:06] <SpeedEvil> You're just chomping it for a PC?
[03:06] <Darkside> nope
[03:06] <Darkside> i'm using DRM stations to get ionospheric channel information
[03:06] <SpeedEvil> Oh - funky.
[03:06] <Darkside> and i want to do it on an embedded system
[03:07] <Darkside> that way you can deploy receivers to strategic locations
[03:07] <SpeedEvil> I suppose they're _lots_ nicer than simple voice as you've got a nice predictable spectrum.
[03:07] <Darkside> yah
[03:08] <SpeedEvil> An actual funded project?
[03:08] <SpeedEvil> Or are you aiming at an amateur ionosphere map project?
[03:08] <Darkside> somewhat funded
[03:09] <Darkside> anyway, it would be a HF transciever
[03:09] <Darkside> separate RX and TX systems
[03:09] <Darkside> TX system would be to send data back to the interested party, probably using PSK or FSK
[03:09] <SpeedEvil> The HF is for net?
[03:09] <Darkside> no
[03:09] <SpeedEvil> Solar panel or something I guess. I mean net = data transfer of results
[03:10] <Darkside> the device would RX DRM data, process it to get the channel response, and then it would TX that data via the HF transmitter
[03:10] <kristianpaul> GPS unpleasant? why?
[03:11] <SpeedEvil> kristianpaul: If you want to decode 18Mbits/s GPS IF samples on a 72MHz processor with no other accelelration
[03:11] <kristianpaul> oh sure :-D
[03:11] <kristianpaul> I tought you meant 100Mhz FPGA at first
[03:12] <SpeedEvil> GPS is _trivial_ with that sort of stuff. :)
[03:12] shipit (~shipit@173-228-28-48.dsl.dynamic.sonic.net) joined #highaltitude.
[03:12] <SpeedEvil> Well - it's annoying to code - but the hardware would be plenty
[03:13] <kristianpaul> trivial for the radio connoisseu..
[03:13] <kristianpaul> r
[03:14] <SpeedEvil> GPS is a fairly simple modulation, which gets reduced down really easily in simple software and you only need to deal with 50bps
[03:14] <kristianpaul> thats after correlation, wich sounds so simple :-)
[03:14] <kristianpaul> correlation, tracking..
[03:15] <kristianpaul> but you're right
[03:15] <SpeedEvil> It is trivial - if you are not looking for fast lock times.
[03:15] <SpeedEvil> The hard part is performing well in very marginal signal conditions.
[03:15] <kristianpaul> had you done it?, because i need some doubts right know
[03:15] <kristianpaul> like real vs complex signal processing :-)
[03:16] <SpeedEvil> No.
[03:16] <SpeedEvil> I've got it to the diagram stage only.
[03:16] <kristianpaul> s/need/have
[03:17] <SpeedEvil> Project stalled unfortunately.
[03:19] <kristianpaul> from you experience can you comment about getting RF IC's for GPS, like those maxim, seems very popular, but i wonder if there are other alternatives, also the people is using
[03:19] <SpeedEvil> I sampled one, with no problems.
[03:20] <kristianpaul> MAX2769?
[03:20] <SpeedEvil> I believe so.
[03:20] <kristianpaul> and besides sample it, you managed to made PCB, and atenna? plus basic acquisition board? :-)
[03:20] <SpeedEvil> No.

[13:14] <eroomde> useful
[13:14] <SpeedEvil> Or outside, close to the neck

[13:15] <Laurenceb> grumble
[13:15] <SpeedEvil> I think that's just the computed out
[13:15] <SpeedEvil> you can read the raw sensor value
[13:16] <SpeedEvil> And it depends on the apature
[13:16] <SpeedEvil> If you reduce the apature, then the temperature goes down.
[13:16] <SpeedEvil> (though you then need to do actual sums to get the temperature)
[13:17] <Laurenceb> yeah
[13:17] <Laurenceb> it should work fine

[13:37] <Dan-K2VOL> good planetary radio podcast today - http://planetary.org/radio/show/00000450/ Long interview about Cassini's radio studies of Saturn
[13:38] <fsphil> anyone any luck receiving the sstv?
[13:38] <junderwood> Dial freq for the RTTY is 434644500
[13:38] Nick change: junderwood -> junderwood_M0JCU
[13:38] <Darkside> i can't hear it!
[13:38] <Darkside> maybe i need a bigger yagi
[13:39] <Darkside> and some *really* good ducting conditions
[13:39] <fsphil> big mast
[13:39] <fsphil> really really big mast, with a really good curve in it
[13:39] <Dan-K2VOL> haha :-P
[13:39] <fsphil> like those things that hold up a globe
[13:39] <Darkside> that'd be a lot of cable loss
[13:40] <BrainDamage> superconductors for the rescue
[13:40] Lee-G4TNX (~Lee-G4TNX@ left irc: Remote host closed the connection
[13:40] <fsphil> hmm.. 434.650 is suspiciously quiet. I think there's too much loss in my cable

[13:42] <Jon-M0JSN> hi all
[13:42] <Jon-M0JSN> weasel decoding alright?
[13:42] <fsphil> some ducting would be nifty -- tracking from 500km away when it's only a few km up
[13:43] <junderwood_M0JCU> Weasel is decoding just fine.
[13:44] <junderwood_M0JCU> Very strong signal

[13:48] <Darkside> well, the payloads then
[13:48] <junderwood_M0JCU> All the checksums are good so it must be something on the payload

[13:51] <ejcweb> Hi everyone - just checking in from the CUSF launch team.
[13:51] <Darkside> hi!
[13:51] <Darkside> we've noticed the GPS doing interesting things
[13:51] <Darkside> some kind of periodic malfunction?
[13:52] <ejcweb> Yes, I see that. Is it every 10 RTTY strings?
[13:52] <Darkside> somethign like that
[13:52] <junderwood_M0JCU> no sign of any SSTV
[13:52] <ejcweb> Re: SSTV and Android - we had to remove all transmission from the phone sadly.

[13:53] <ejcweb> junderwood_M0JCU: So sorry for keeping you looking, but thank you!
[13:53] <junderwood_M0JCU> np
[13:53] <junderwood_M0JCU> only had a quick glance.
[13:53] <ejcweb> There was some signal interference between Squirrel and Weasel
[13:53] <junderwood_M0JCU> Signal is very strong. What antenna are you using?
[13:54] <ejcweb> It's just a standard quarter wave antenna.
[13:54] <ejcweb> Not sure why in particular it should be so strong, but that is great; thanks for tracking!
[13:55] <ejcweb> jonsowman & Randomskk and a couple more have set off in the chase car.
[13:55] <junderwood_M0JCU> I think they may need a boat :)
[13:55] <ejcweb> Ah, that was indeed a risk.
[13:56] <Dan-K2VOL> ejcweb I do think those rodents are fundamentally incompatible
[13:56] <ejcweb> Though the last time we ran the tracker it was looking remarkably good (~1pm I thought). I haven't checked since.
[13:57] <junderwood_M0JCU> Tracker suggests it will reverse its track at B-S-E. We'll see
[13:57] <ejcweb> junderwood_M0JCU: That's the hope...
[13:58] <ejcweb> Of course if Weasel breaks for some reason, we've still got text location finding on the phone.

[14:02] <Upu> trying to use global tuners to listen in but the audio keep stopping
[14:03] <Dan-K2VOL> ugh globaltuners - a nice idea, a bad implementation
[14:03] <ejcweb> So the periodic malfunction is this: nav mode on the gps is reset every 10 strings to stop it accidentally changing mode as we've experienced before. obviously this is affecting gps lock for the subsequent telemetry string.
[14:04] <ejcweb> Or at least, that's how I understand it - I didn't make Weasel so couldn't say for sure.
[14:08] <fsphil> another 5km or so before I can receive it I think
[14:08] <fsphil> the rain is really coming down hard here now
[14:08] <fsphil> wonder if that will weaken the signal

[14:11] <SpeedEvil> I have a spare DSL modem, so I just unplug it all and go on battery.
[14:12] <Upu> what frequency is it on and how often is it transmitting ?

[14:14] <Upu> Globaltuner in Kessingland can't hear it
[14:14] <Upu> mind you know knows what antenna is on it
[14:14] <Dan-K2VOL> ejcweb did you launch into the clouds?
[14:14] <Upu> Antron 99
[14:15] <ejcweb> Dan-K2VOL: It was actually looking pretty clear when we launched, and it's ascent was not directly into clouds.
[14:15] <ejcweb> Though after a couple of minutes it started clouding over again so probably has ascended through cloud to some extent.
[14:16] <Dan-K2VOL> nice
[14:16] <The-Compiler> anyone here ever thought about casualty insurance? I want to start my own HAB project, but with a payload > 500g you need to have a casualty insurance of at least around 1 Mio. dollar, and I have no idea what that will cost
[14:16] <The-Compiler> (here in Switzerland, that is)
[14:16] <Dan-K2VOL> The-Compiler I'm sorry for your laws
[14:17] <BrainDamage> where in switzerland ouf of curiosity?
[14:17] <The-Compiler> Me? Winterthur, near Zurich.
[14:17] <Dan-K2VOL> amateurs that I know of have not had good luck with getting people to insure them for any reasonable amount of money
[14:17] <BrainDamage> mmm, ~300 km from here, como, italy
[14:18] <The-Compiler> I guess I'll just call my insurance company and see what they tell me... Aeromodelling is very common in Switzerland after all, and there are insuranced specialized on that
[14:18] Lee-G4TNX (~Lee-G4TNX@ left irc: Remote host closed the connection
[14:18] <The-Compiler> and if it's too expensive I just need to see how I can keep the payload < 500g... should be doable
[14:18] <Dan-K2VOL> The-Compiler some of the cambridge guys got it once I think though,
[14:19] <The-Compiler> because 0-499g is automatically insuranced or something like that
[14:19] <Dan-K2VOL> it's difficult to find an insurance company that will quote such insurance, as they usually know nothing about it
[14:20] <Dan-K2VOL> less than 500g is certainly possible, it's a challenge though
[14:20] <The-Compiler> BrainDamage: no idea where I will launch, depends on the prediction, because I'd like it to land in Switzerland and we're small :D
[14:21] <Dan-K2VOL> speaking of not small, I'm surprised we don't hear more canadians doing launches
[14:21] <The-Compiler> well, http://www.luftfahrtversicherungen.ch already sounds promising, they seem to be specialized to aero stuff, I might contact them
[14:21] <imrcly> Dan-K2VOL: we never looked to see if we needed to pay export taxes
[14:21] SpeedEvil (~user@tor/regular/SpeedEvil) left irc: Ping timeout: 255 seconds
[14:21] <Dan-K2VOL> haha imrcly
[14:21] <Upu> gah
[14:22] <Upu> Global Tuners is rubbish :)
[14:22] <Dan-K2VOL> upu I concur
[14:22] <ejcweb> The-Compiler: I'm coming to Zurich for an internship for 3 months this summer :)
[14:22] <The-Compiler> and for me, up to 150$ or so for the insurance won't hold me back
[14:23] <Upu> found one that works and the audio just cuts out and stops then won't restart
[14:23] <Dan-K2VOL> The-Compiler the quotes we got in the USA were around $7000 USD for 5 flights :-(
[14:23] <fsphil> still nothing here
[14:24] <The-Compiler> ow o_o
[14:24] <Dan-K2VOL> but do check, companies may be more reasonable over there
[14:24] <junderwood_M0JCU> fsphil, I didn't get a hint of the last Hadie until about 20km - and I'm closer to you than you are to Cambridge
[14:25] <Dan-K2VOL> honestly there's not a huge rate of damage being done by amateur balloons
[14:25] <The-Compiler> the risk is certainly high... Don't wanna imagine what happens when the parachute drops off or something
[14:25] <BrainDamage> you can styrofoam pad it
[14:25] <BrainDamage> and keep density low
[14:25] <The-Compiler> won't help if something is coming down from 30km height
[14:26] <imrcly> there is a legal density requirement
[14:26] <Dan-K2VOL> heh BrianDamage, the regulation to keep under 500g is actually going to make adding styrofoam difficult after you add your electronic weight
[14:26] <Upu> Ava is 850g
[14:26] <ejcweb> Does anyone here know anything about setting up the dynamic predictor?

[14:27] <The-Compiler> Hell, if it doesn't work out I'm just going to Italy, Germany or France and do it there.
[14:28] <Upu> its switch on the tracker isn't it ?
[14:28] <Upu> I don't know how to do it
[14:28] <Dan-K2VOL> good plan The-Compiler
[14:29] <The-Compiler> I'm kinda close to all of them anyways.
[14:30] <BrainDamage> btw, since you're close to zurich, do you happened to remember the famous waterfall near there?
[14:30] <junderwood_M0JCU> ejcweb, since it is well to the east of the prediction, I would suggest he heads for the A140 somewhere between Stwomarket and Diss
[14:32] <fsphil> junderwood_M0JCU, for most cambridge launches it seems to start coming in here around 15/16km
[14:32] <fsphil> though this one is further south and east than usual

[14:38] <junderwood_M0JCU> ejcweb, best guess using my predictor and wild guesses about the parachute system is landing somewhere near Gislingham

[14:45] <ejcweb> Great, thanks junderwood_M0JCU . I've passed that onto the chase car. They're currently approaching Stowmarket and will probably take the A140 north from there. I imagine that they will get internet connected shortly and be IRC active.
[14:47] <junderwood_M0JCU> ejcweb, I suggest they stop somewhere near the Thornham Magna turn off the A140. That should put them within a few miles of the landing (assuming 30km burst)

[15:11] <ejcweb> I'll message you his mobile number just in case.
[15:11] <Dan-K2VOL> I doubt it fsphil, if you consider the record that cornell set

[15:11] <junderwood_M0JCU> USB. Yes
[15:12] <ejcweb> Ok, we reckoned not given its altitude.
[15:12] <fsphil> aah, starting to get numbers and commas

[15:12] <SpeedEvil> They could do the other altitude record
[15:12] <eroomde> what's the predicted burst alt?
[15:13] <Dan-K2VOL> and I am doubtful of the cornell flight being considered amateur, since they used a 150,000 cu ft Aerostar zero pressure balloon that no amateur can buy :-)

[15:13] <SpeedEvil> http://en.wikipedia.org/wiki/Extremes_on_Earth#Extreme_elevations_and_temperatures_per_continent
[15:13] <eroomde> oh i think higher
[15:13] <eroomde> if it's a 2kg balloon
[15:13] <eroomde> and a wee payload
[15:13] <Dan-K2VOL> what is the payload weight?
[15:13] <eroomde> and a fairly pedestrain ascent rate
[15:15] <eroomde> oh but it's using the crazy bitch orange parachute
[15:15] <eroomde> http://www.srcf.ucam.org/~ejc74/balloon.JPG
[15:15] <eroomde> on the right
[15:15] <eroomde> that weighs about 1.5kg on its own

[15:16] <Randomskk> hi all

[15:17] <Randomskk> junderwood_M0JCU: where is this place we should wait for the balloon?
[15:17] <eroomde> Randomskk: what is the mass at the neck and the balloon size?
[15:17] <fsphil> got a burst of numbers
[15:17] <fsphil> it's getting there
[15:18] <junderwood_M0JCU> For 30km you need to be somewhere up the A140 about half way to Diss
[15:18] <Randomskk> eroomde: no idea about neck mass in the end, we didn't weigh it
[15:18] <eroomde> approximately?
[15:18] <junderwood_M0JCU> If it goes higher, the landing spot moves West quite quickly
[15:18] <eroomde> big or little payload? and using the big orange shute, yeah?
[15:18] <Randomskk> jon estimates 1kg
[15:18] <Randomskk> big orange shute, two poly boxes payload but nothing much in either of them
[15:18] <Randomskk> the android went without ntx2 or batteries so just the phone
[15:19] <eroomde> well the orange chute is >1kg on its own
[15:19] <Randomskk> 72" aerocon shute
[15:19] <eroomde> but fine, fairly light
[15:19] <eroomde> and what size balloon?
[15:19] <Randomskk> 2000g
[15:19] <Randomskk> ~3.5, 4kg neck lift
[15:19] <eroomde> ok, so it'll happily cruise past 30km

[15:19] <mixio> :)
[15:19] <Randomskk> given neck lift was about 4kg and ascent has been about 4, I guess it should be possible to find the neck mass
[15:20] <eroomde> nice work mixio
[15:20] <eroomde> couple of comments
[15:20] <eroomde> 1) tape the batteries down on the main flight board
[15:20] <junderwood_M0JCU> have to go out for a minute. I'll leave the radio
[15:20] <eroomde> 2) if you fly that breadbaord, make sure the wires are secured down!
[15:23] <mixio> the batteries of the main board cannot be moved. They are fixed.
[15:23] <Elwell> mixio: what GPS chipset is that?
[15:23] <eroomde> i know where this is going...
[15:23] <Elwell> esp on the bottom right of the bottom pic
[15:23] <junderwood_M0JCU> Current prediction is somewhere near "4 ashes" if it bursts now
[15:24] <mixio> Elwell: main board gps is GPS Bee
[15:24] <eroomde> this is just a guess and i don;t know anything about these new style 2kg balloons, but i'd have thought we could be looking at more like 35km
[15:25] <mixio> my payload should not weight more than 800grams. What altitude will it reach with a 1200 balloon?
[15:25] <Randomskk> right we are getting underway up the A140, will stop stoke ash and wait for burst/more info then see if we can't catch it coming down :P

[15:34] <fsphil> signal has faded here, likely in a null
[15:34] <fsphil> I need a pre-amp :)
[15:35] <fsphil> well, I have a pre-amp. I just need to build it
[15:35] <Upu> if this stays up I might even get home in time to get the radio on
[15:35] <fsphil> you should get a lovely signal
[15:35] <Upu> I know
[15:35] <Upu> annoying
[15:35] <fsphil> if it wasn't raining I'd get out the yagi

[15:37] <GW8RAK> Just sat down in the office and this launch is really good. Was it after an altitude record?
[15:38] <Upu> dunno but its going to get it
[15:38] <eroomde> ascent rate slowing down?
[15:38] <Upu> yep
[15:38] <eroomde> could be the limit of the latex to draw
[15:38] <eroomde> therefore imminent burst
[15:39] <fsphil> or could start floating
[15:39] <Upu> pop ?
[15:39] <Upu> oh no
[15:39] <Upu> my bad just blipped

[15:39] <eroomde> well, not bug but some kind of hack i think
[15:39] <Upu> k
[15:40] <eroomde> as the gps was getting a bit screwey without occassional reseting

[16:04] <eroomde> lets hypothesise this bobbing, peeps. fluids aren't my thing
[16:05] <fsphil> stronger again -- getting most of the strings, just a few characters bad
[16:05] <eroomde> it could be that it's moving with an oscillating air mass, so 0 relative vertical air speed
[16:05] <junderwood_M0JCU> Randomskk, landing position is now about 2 miles north of Newmarket. Heading west
[16:05] <eroomde> or it could be that it's bobbing ontop of the thicker air, bounding around, as the pressure gradiants are really high at that altitude
[16:05] <GW8RAK> 3m to go
[16:05] <fsphil> 36km

[16:11] <fsphil> yea, the minus sign is missing
[16:11] <eroomde> i should say - this flight computer was a project by two of our new first-year recruits
[16:11] <eroomde> i'm not sure it's been tested!
[16:11] <Matt_soton> it went from 0.11 -> 0.10 -> 0.9
[16:11] <junderwood_M0JCU> I think it is just missing a zero from the position
[16:11] <junderwood_M0JCU> for 0.5675 read 0.05675
[16:12] <fsphil> I suspect the baud rate isn't exactly 50
[16:12] <fsphil> oooh that kind of bug
[16:12] <Dan-K2VOL> ah that's why I insist on GPS simulations of the entire potiential flight area - it must survive crossing the meridian and equator
[16:12] <eroomde> well we are only 5 miles from it
[16:12] <Dan-K2VOL> lol you could test that with a walk
[16:12] <eroomde> so we drive backwards and forwards across it on the dual carriageway between two exits
[16:13] <eroomde> whilst live-coding
[16:13] <Dan-K2VOL> hahaa that's awesome
[16:13] <fsphil> I used fake gps
[16:13] <fsphil> though I'm pretty far from the meridian, not likely to be a concern for me
[16:13] <Dan-K2VOL> never know, it could randomly float like this!
[16:13] <fsphil> but I'd be gutted if someone else used my code and I hadn't thought of that
[16:13] <junderwood_M0JCU> Real position is 52.2914, 0.02698, 36124

[16:17] <junderwood_M0JCU> 34542
[16:17] <Dan-K2VOL> we failed to do that for SNOX IV and couldn't tell if oscillations were real or GPS altitude calculation fluctuations

[16:48] <Dan-K2VOL> hi Jcoxon
[16:49] <SpeedEvil> What's the cause of hte altitude booogons?
[16:49] <junderwood_M0JCU> possible. It's still coming down way slower than my prediction. Time for a prediction change. Hold on!
[16:49] <jcoxon> ooo float
[16:49] <Upu_2E0UPU> 17 mins left ?
[16:49] <SpeedEvil> I make it bangish in the middle of burwell
[16:49] <SpeedEvil> actually - no
[16:49] <SpeedEvil> old prediction - oops
[16:50] <Upu_2E0UPU> goign much slower now
[16:51] <fsphil> hehe, I got home before it landed
[16:51] <fsphil> nice
[16:51] <Upu_2E0UPU> 2km more I reckon
[16:51] <SpeedEvil> Burwell road - between burwell and exing
[16:51] <Upu_2E0UPU> tracking..
[16:51] <SpeedEvil> (based on the predictor)
[16:52] <junderwood_M0JCU> Randomskk, B1103 was better I think. Sorry!
[16:52] <Upu_2E0UPU> its tracking across ground at about 1km a min
[16:53] <junderwood_M0JCU> The way the predictions are changing, it could land in Exning
[16:53] <Randomskk> junderwood_M0JCU: back on it now and heading to a layby
[16:53] <Randomskk> b1103 that ais
[16:53] <Upu_2E0UPU> *cough* [17:47] <Upu_2E0UPU> my crap calcs put it closer to Exning
[16:53] <Randomskk> okay we're parked on the b1103
[16:53] <SpeedEvil> b1103 looks likely
[16:53] <Upu_2E0UPU> yes I'd go with that
[16:53] <junderwood_M0JCU> It would be a lot easier if people weighed their payloads :)
[16:53] <jgrahamc> Nail biting stuff
[16:54] <Upu_2E0UPU> should be able to see it you got some binoculars ?
[16:54] <Randomskk> no binocs
[16:54] <Randomskk> :P
[16:54] <Upu_2E0UPU> 10 mins out :)
[16:54] <junderwood_M0JCU> B1103 on outskirts of Exning looks good to see it down
[16:54] <fsphil> not too many trees
[16:54] <fsphil> excellent
[16:55] <SpeedEvil> Probably a bit too far yet for eyeballs.

[17:00] <Upu> yep :)
[17:00] <junderwood_M0JCU> I currently have it in the clump of trees just near the big building on Cotton End Rd
[17:00] <cuddykid> Hi all, just got in, anyone update me on launch? Please say its not another tree incident?!?!?!
[17:00] <SpeedEvil> Not yet.
[17:00] <Dan-K2VOL> haha nooooo
[17:00] <Upu> might be just stick about cuddykid :)
[17:01] <SpeedEvil> Err - I mean - no, of course not.
[17:01] <Upu> its about 5 mins from landing
[17:01] <cuddykid> oh right! cool
[17:01] <cuddykid> just in time!
[17:01] <SamSilver_> cuddykid: it was a bit of a floater
[17:01] <cuddykid> wow, there's been some dodgy data feeding through to tracker by the looks!
[17:01] <cuddykid> cool
[17:02] <Upu> no data was fine just the code was giving wrong longditude
[17:02] <cuddykid> ahh right
[17:02] <cuddykid> is it that 0 degree line causing probs again?
[17:02] <Upu> think so
[17:02] <jgrahamc> Likely visible at this altitude
[17:03] <cuddykid> btw Upu, should have my styrofoam tomorrow :D
[17:03] <Upu> have fun with it
[17:03] <junderwood_M0JCU> Randomskk, There is a road running parallel to Cotton End Rd and just to the west, off North End.
[17:03] <Upu> wire cutter is the way to go
[17:03] <Upu> you still got it M0JCU ?
[17:04] <junderwood_M0JCU> It will be 360 yards up there.
[17:04] <junderwood_M0JCU> In open fields

[17:49] <cuddykid> jcoxon: will be getting IMU and having a play around. Looked at ardupilot but but of an overkill for what I need
[17:49] <cuddykid> not entirely sure on design of glider yet
[17:49] <jcoxon> i meant from a legality point of view
[17:49] <jcoxon> (not to put a dampner on things!)
[17:49] <Laurenceb_> cuddykid: well the avr is a bit underpowered
[17:49] <Laurenceb_> cuddykid: a directional chute is more legal

[17:49] <Laurenceb_> well aiui it is legal :D
[17:51] Action: SpeedEvil hugs the right to roam.
[17:51] <cuddykid> oh! urm, haven't checked that out yet, I was under impression that provided it's unpowered then it should be ok if keeps in size/weight guidelines
[17:51] <Laurenceb_> yeah they can tell you to get off the land, but its not like you can face consiquences for being on farmland
[17:51] <Dan-K2VOL> well that's nice

[18:39] <cuddykid> was planning on trying to code my own v basic one
[18:39] <Laurenceb_> then id go yaw gyro and gps
[18:39] <cuddykid> such as, find angle of pitch, if >10degrees then adjust aileron
[18:39] <Laurenceb_> and a chute of some sort, pref a rogallo as it cant tangle up

[20:11] <nickolai89> yea i intend to, just haven't gotten around to it yet
[20:11] <Dan-K2VOL> are you involved in a hackerspace?
[20:11] <nickolai89> no, what's that?
[20:11] <Dan-K2VOL> it's easy to fiddle with the predictor
[20:12] <Dan-K2VOL> oh my, where do you live in NJ this summer
[20:12] <nickolai89> in the northern half, kinda far from anything interesting except morristown

[20:47] <hibby> hurrah!
[20:47] <hibby> us visa!
[20:48] <Lunar_Lander> yay
[20:48] Hiena (~boreger@ left irc: Remote host closed the connection
[20:48] <Lunar_Lander> well done hibby
[20:49] <hibby> total waste of my money, getting it, though
[20:49] <hibby> I went to my interview, which cost $140. They took my recipt, confirmation of interview, let me sit for 40 minutes, took me in and told me to enjoy my stay, I've been granted a visa and i'll receive my passport in a few days
[20:49] <Lunar_Lander> yeah
[20:50] <Lunar_Lander> so the interview wasn't really many question?
[20:50] <Lunar_Lander> +s
[20:50] <hibby> not to include the $150 flights to the consul, and $70 assorted logistics surrounding it.
[20:50] <hibby> Lunar_Lander: none - they just processed forms I submitted online
[20:50] <Lunar_Lander> ah
[20:50] <Lunar_Lander> sounds easy
[20:51] <hibby> was totally painless. Just danged expensive, sadly.
[20:51] <hibby> lovely day out in belfast, though
[20:51] <Lunar_Lander> yeah

[20:54] <hibby> amazing
[20:54] <Randomskk> back home
[20:54] <Randomskk> uuugh
[20:54] <hibby> looks like something out the original half life
[20:54] <Lunar_Lander> yeah
[20:54] <Lunar_Lander> I remember that room
[20:54] <Upu> hey Randomskk
[20:54] <Upu> did you get it back ?
[20:54] <Randomskk> no :(
[20:55] <Upu> stuck up a tree ?
[20:55] <Randomskk> ~25m up a tree in a thick forest between two fields with cows and a bull
[20:55] <Lunar_Lander> hibby I wonder what the system is used for
[20:55] <Randomskk> the farmers were kind of helpful but didn't really have anything suitable and can't be cutting down their trees
[20:55] <Upu> so whats the plan ?
[20:55] <Randomskk> we've left contact details in the hope it blows out
[20:55] <Lunar_Lander> as far as I see, the beam is just guided once around the table
[20:55] <Upu> ah ok

[20:55] <Randomskk> as maybe they'll have like a tractor with a cherry picker or something
[20:55] <Randomskk> however everyone goes home for holiday like tomorrow/saturday
[20:56] <Upu> Think I'm going to put some ladders on the roof when I do mine :)
[20:56] <Randomskk> so either they hold onto it or post it or something, or maybe jonsowman and I are coming back to cambridge in a month ish, or who knows
[20:56] <Randomskk> might just have lost it
[20:56] <Lunar_Lander> hibby Randomskk Upu
[20:56] <Randomskk> ladders wouldn't be much help, it was maybe 5 or 6m out from the tree trunk on a thin branch
[20:56] <Lunar_Lander> sorry
[20:56] <Upu> take any pictures of it up the tree ?
[20:56] <Upu> hey Lunar_Lander
[20:56] <Lunar_Lander> *hi Upu Randomskk
[20:56] <Randomskk> yea though not on my camera
[20:56] <Lunar_Lander> :)
[20:56] <kristianpaul> Probing data (../GNSS_signal_records/GPS_and_GIOVE_A-NN-fs16_3676-if4_1304.bin)...
[20:56] <Lunar_Lander> Randomskk did you fly?
[20:56] <hibby> :)
[20:56] <kristianpaul> number of rows must match (0 != 1) near line 145, column 32 (run setSettings or change settings in "initSettings.m" to reconfigure)
[20:56] <kristianpaul> :S
[20:56] <Upu> another payload lost to trees :/
[20:56] <Randomskk> 13 hours from leaving college to getting back :/
[20:57] <Randomskk> still, UK altitude record
[20:57] <hibby> Randomskk: nice one.
[20:57] <Upu> yeah
[20:57] <Upu> would love to see the ictures
[20:57] <Upu> oh well guess we'll have to wait
[20:57] <hibby> how about we say a chansaw, saw or axe are essential tools now ;)
[20:57] <Randomskk> yea really a shame
[20:57] <Randomskk> plus there was a nexus 1 in there
[20:57] <Randomskk> and a nice parachute
[20:57] <Randomskk> all a bit of a shame
[20:58] <Lunar_Lander> Randomskk what is your altitude?
[20:58] <Randomskk> also exhausting
[20:58] <Randomskk> Lunar_Lander: I dunno, it hit 36.something km
[20:58] <kristianpaul> Laurenceb_: had you experienced the message i posted above?
[20:58] <jcoxon> Randomskk i feel your pain
[20:58] <Randomskk> jcoxon: haha I bet
[20:58] <Lunar_Lander> well done!
[20:58] <Randomskk> though cutting the tree down is definitely not an option this time :P
[20:58] <Upu> 36206 m
[20:59] <hibby> Randomskk: just go at night
[20:59] <Randomskk> which is 15th best on the ARHAB records, too
[20:59] <Upu> what was the offical name of the pay load ?
[21:00] <Randomskk> weasel I guess
[21:00] <Laurenceb_> kristianpaul: sorry whats this a problem with?
[21:01] <Lunar_Lander> Randomskk and it landed on a tree on a private ground
[21:01] <Lunar_Lander> ?
[21:01] <Randomskk> Lunar_Lander: yea
[21:01] <Lunar_Lander> oh no
[21:01] <Upu> http://ukhas.org.uk/general:uk_records
[21:01] <Upu> there you go
[21:01] <Upu> grats
[21:01] <kristianpaul> Laurenceb_: he :),sorry, i'm trying to run SoftGNSS code from borre, i just run init.m with matlab after hacl others files claiming for right values..
[21:01] <Lunar_Lander> xD the dot is confusing
[21:01] <Upu> I text Rob Harrison and told him he's now second :)
[21:01] <Randomskk> Upu: thanks :D
[21:02] <Lunar_Lander> because in germany, it has the function that the comma has in english Upu
[21:02] <Randomskk> so yea, we got stung all over crawling through nettles to try and spot the payload up a tree
[21:02] <Randomskk> had a herd of 20 cows start charging towards us
[21:02] <Randomskk> nearly got run at by a bull
[21:02] <Lunar_Lander> a german would probably read 36206 km
[21:02] <Lunar_Lander> congratulations, you reached GEO orbit
[21:02] <Lunar_Lander> xD
[21:02] <Randomskk> spent 4 hours within 500m of the payload trying to get to it
[21:02] <kristianpaul> Laurenceb_: i manage to get the same code shipped on the DVD :-)
[21:02] <Lunar_Lander> yeah
[21:02] <Upu> 36,206 km = space 36.206km = sky
[21:03] <Laurenceb_> kristianpaul: where from?
[21:03] <fsphil> know that feeling Randomskk
[21:03] <Lunar_Lander> Upu yeah :P
[21:03] <Randomskk> my phone totally ran out of battery from wifi tethering :P
[21:03] <Lunar_Lander> Upu of course I know what the dot means
[21:03] <Lunar_Lander> ;)
[21:03] <Upu> ok afk walking dog
[21:03] <Randomskk> and now jonsowman actually has a 2-3 hour drive home :P
[21:03] <Lunar_Lander> Upu ttyl
[21:03] <Lunar_Lander> WHOA
[21:03] <Lunar_Lander> it's calm outside
[21:03] <Randomskk> so he's been driving for hours and hours
[21:04] <Lunar_Lander> and suddenly a bright lightning bolt to the NW
[21:04] <Lunar_Lander> !
[21:04] <Lunar_Lander> multiple flashes, a little bit red
[21:04] <Laurenceb_> kristianpaul: sorry its been ages since i ran the code
[21:04] <kristianpaul> Laurenceb_: a guy who bought the book, so i asked for the dvdv content, and he sent me the code and a part of the sample data
[21:04] <Laurenceb_> neat
[21:04] <kristianpaul> Laurenceb_: ages..
[21:04] <Laurenceb_> i have the dvd somewhere, sorry i can find it atm
[21:04] <kristianpaul> Laurenceb_: but you ran it with octave right?
[21:04] <Laurenceb_> like 2 years
[21:04] <kristianpaul> no problem
[21:05] <Lunar_Lander> now it thunders
[21:05] <Laurenceb_> yes, after some changes
[21:05] <Lunar_Lander> it must be really far away
[21:05] <kristianpaul> Laurenceb_: but you have the forked code?
[21:05] <kristianpaul> i still not getting all this to wrok.. :S
[21:06] <Lunar_Lander> Randomskk I hope that you get the opportunity to get your payload back
[21:06] <Randomskk> yea hopefully! we'll do what we can
[21:06] <SpeedEvil> Good luck!
[21:06] <kristianpaul> may be a clue to debug last message i posted http://paste.debian.net/120776/
[21:07] <Lunar_Lander> bte
[21:07] <Lunar_Lander> *btw
[21:07] <Lunar_Lander> does anybody know what Robert does now?
[21:07] <kristianpaul> Laurenceb_: is a bit confusing, well i never run something so comlex in octave before...
[21:07] <Lunar_Lander> Icarus III-2? Icarus IV?

[21:09] <Lunar_Lander> this GPS http://www.coolcomponents.co.uk/catalog/product_info.php?products_id=518
[21:10] <Laurenceb_> kristianpaul: try checking the errors - hopefully it can be solved with simple changes
[21:10] <Laurenceb_> i had an issue where the PRN code numbers were off by one
[21:10] <jcoxon> Lunar_Lander, excellent
[21:10] <Lunar_Lander> does anybody know if this is a GPS with speed limit only?
[21:10] <Laurenceb_> also some of the rounding in the position filter needed changing to improve accuracy
[21:10] <kristianpaul> Laurenceb_: did yousee the last error i pasted?
[21:11] <kristianpaul> i dont get what's wrong witht the columns..
[21:11] <kristianpaul> but anyway.. i'll keep checking :-|
[21:12] <Lunar_Lander> jcoxon do you know it maybe?
[21:12] <kristianpaul> Laurenceb_: jsut in case you miss it http://paste.debian.net/120776/

[21:13] <Lunar_Lander> We've had some success with the Venus GPS. It's integrated into our
[21:13] <Lunar_Lander> 'BadgerCub' flight computer:"
[21:13] <Lunar_Lander> sounds good
[21:13] <Randomskk> it's actually rubbish
[21:13] <kristianpaul> Laurenceb_: the rror is there right.. but in wich file, is not clear forme]
[21:13] <Randomskk> we're changing the GPS on badgercub
[21:13] <Randomskk> it works but
[21:13] <Lunar_Lander> oh ok
[21:13] <Randomskk> meh
[21:14] <Randomskk> well no, that's not fair - it's fine for ballooning
[21:14] <Randomskk> and you can get it w/o altitude limits
[21:14] <Randomskk> so by all means use it
[21:14] <Lunar_Lander> Randomskk what do you recommend?
[21:14] <Randomskk> ublox6 series or something are sexy
[21:14] <Lunar_Lander> now I'm confused
[21:14] <Randomskk> yea saying it was rubbish was unfair, it's not that bad
[21:14] <Randomskk> just we are changing it out for newer hotter things
[21:14] <Lunar_Lander> yeah
[21:15] <Lunar_Lander> is it possible to find out if the breakout I linked to has the speed limit?
[21:15] <Lunar_Lander> in the datasheet maybe?
[21:15] <Randomskk> it's to do with the software, but I didn't really do much with that
[21:16] <Lunar_Lander> oh ok
[21:19] <Upu> Lunar_Lander Icarus had different flight computers called 1, 2 and 3
[21:19] <Lunar_Lander> yeah
[21:19] <Lunar_Lander> and III is still good?
[21:19] <Upu> Yeah but Rob hasn't been about for a bit
[21:20] <Lunar_Lander> yeah
[21:20] <Lunar_Lander> jcoxon said that family is now is prime prioriy
[21:20] <Lunar_Lander> +t
[21:20] <Upu> yup
[21:24] <Lunar_Lander> so
[21:24] <Lunar_Lander> I get that the Venus is OK?
[21:26] <Lunar_Lander> Randomskk could you maybe help me how to contact the person who programmed it for you?
[21:26] <Randomskk> eroomde would be the person to ask
[21:26] <Lunar_Lander> ah thanks
[21:26] <Lunar_Lander> eroomde is here?
[21:29] <nickolai89> Just got back, congrats on the altitude record Randomskk - shame you can't get the payload down though

[21:42] <jcoxon> i don't know
[21:42] <jcoxon> mine was high

[22:07] <Lunar_Lander> yeag
[22:07] <Lunar_Lander> yeah
[22:07] <fsphil> I'm getting my bots mixed up
[22:07] <fsphil> best thing about that machine was the noise
[22:07] <Lunar_Lander> but tornado had a small vertical spinner
[22:07] <Lunar_Lander> yeah
[22:08] <Lunar_Lander> sad that Hypno-Disc never became UK champion
[22:09] <Lunar_Lander> fsphil did you ever see RW live?
[22:09] <fsphil> didn't nope

[22:10] <jcoxon> e
[22:10] <fsphil> I've probably seen him on it
[22:10] <jcoxon> you'll ahve to ask him next time he is on
[22:10] <BrainDamage> they ban all the fun stuff
[22:11] <BrainDamage> like, max circuit voltage, 50V
[22:11] <Lunar_Lander> yeah
[22:11] <BrainDamage> I guess tought, that thanks to supercaps, one could add arc weapons
[22:11] <Lunar_Lander> what was the team with the very expensive robot again?
[22:11] <Lunar_Lander> they only were in until Series 4
[22:11] <Lunar_Lander> Mortis I think
[22:11] <fsphil> I'd say quite a few where very expensive
[22:12] <fsphil> Razor looked expensive
[22:12] <Lunar_Lander> yeah
[22:12] <Lunar_Lander> Chaos 2 was a simple but effective design
[22:13] <SpeedEvil> Especially if you count time.
[22:14] <Lunar_Lander> yeah
[22:14] <Lunar_Lander> the thing with Razer having all the holes was the weight limit
[22:14] <Lunar_Lander> I think it was 83 kg in the first years
[22:14] <Lunar_Lander> they raised it to 100 only later
[22:14] <fsphil> made it look better
[22:14] <Lunar_Lander> yeah
[22:14] <fsphil> I had an idea for a bot but.. well I'm rubbish at building robots
[22:15] <Lunar_Lander> I think all kinds of axes are not so good

[22:15] <hibby> Razor had a few hydraulic issues to
[22:15] <Lunar_Lander> yeah
[22:15] <Lunar_Lander> In series 3, it was stuck in self-righting mode
[22:15] <Lunar_Lander> and the rear of the beak raised the wheels of the floor
[22:15] <fsphil> remember that
[22:16] <hibby> the forces translated were pretty huge and sometimes the system would shit itself and the reinforced metal pipes would fly off at high speed.
[22:16] <Lunar_Lander> yeah
[22:16] <Lunar_Lander> there were two German and two Dutch series I think
[22:16] <hibby> went to see it live
[22:16] <Lunar_Lander> the first had one fight Germany v. UK
[22:16] <fsphil> you lucky persons hibby
[22:16] <Lunar_Lander> and the second one a whole series GER v. UK
[22:17] <Lunar_Lander> the first one was Hypno-Disc vs. a german bot which I have forgotten
[22:17] <Lunar_Lander> but this was made from a shopping cart
[22:17] <fsphil> I did always cringe a bit when Craig Charles did his little rhyme at the end though
[22:17] <Lunar_Lander> which actually caused HD to fail
[22:17] <Lunar_Lander> I think the disc motor stopped after a few strikes

[22:18] <Lunar_Lander> and next year, there was Fluffy vs. "Das Gepaeck" in the final
[22:18] <fsphil> They seemed to re-dub the sound though, never understood that
[22:19] <Lunar_Lander> and the latter team added a little square tube to the height of fluffy's blade
[22:19] <Lunar_Lander> and that also caused the blade motor to fail
[22:19] <Lunar_Lander> it went to the judges and Das Gepaeck won

[22:19] <Lunar_Lander> xD
[22:19] <Lunar_Lander> btw
[22:20] <Lunar_Lander> the German and Dutch series were like the first UK series
[22:20] <Lunar_Lander> that was between UK Series 5 and 6 I think
[22:20] <fsphil> presented by Clarkson?
[22:20] <Lunar_Lander> you could see that robot building was not reall advanced on the continent
[22:20] <Lunar_Lander> no no xD
[22:20] <fsphil> that first series was pretty bad :)
[22:20] <Lunar_Lander> whoa Clarkson always bashed the roboteers
[22:20] <Lunar_Lander> xD
[22:21] <Lunar_Lander> yeah, that Gauntlet and Trial were still in right?
[22:21] <fsphil> yea, it was more robot vs. the course, than robot vs. robot
[22:21] <Lunar_Lander> yeah
[22:21] <Lunar_Lander> xD I think it had that box with industry drills coming out of it
[22:21] <Lunar_Lander> and they were just coming out
[22:21] <Lunar_Lander> not spinning
[22:21] <Lunar_Lander> xD
[22:22] <Lunar_Lander> I think a low ground clearance also was bad at that time
[22:22] <fsphil> Razor wouldn't have done well on the first series at all
[22:22] <Lunar_Lander> yeah

[22:23] <fsphil> really tiny wheels
[22:23] <Lunar_Lander> yeah
[22:23] <Lunar_Lander> and the arena had some spikey ball swinging around which did nothing really
[22:24] <Lunar_Lander> and no pit
[22:24] <Lunar_Lander> and no flipper
[22:25] <fsphil> I liked the one that was just two wheels and a mace, Stinger
[22:25] <Lunar_Lander> yeah!
[22:25] <fsphil> lovely design - but I bet almost impossible to drive
[22:25] <Lunar_Lander> did you see the american original? "The Master"
[22:26] <Lunar_Lander> http://www.youtube.com/watch?v=4tKm82FQu34
[22:26] <fsphil> dont' remember that one
[22:26] <Lunar_Lander> but that saw shattered often
[22:26] <Lunar_Lander> wouldn't have been allowed in the UK
[22:26] <BrainDamage> I'd add a pressurized fuel tank, and wheel with nozzles on 2 sides
[22:27] <BrainDamage> spin the wheel, regulate stream output
[22:27] <BrainDamage> make wall of a fire
[22:27] <BrainDamage> -a
[22:27] <Lunar_Lander> fsphil and a middleweight one from the US was "Agamemnon"
[22:27] <Lunar_Lander> had a spike turret rotatable
[22:27] <BrainDamage> alternatively, iodine chemical laser, pulsed operation around 1MW
[22:27] <Lunar_Lander> and a cam with video glasses for the crew
[22:28] <Lunar_Lander> http://www.youtube.com/watch?v=7EAj8rsoQ9c
[22:28] <fsphil> lol, it's a petrol driven robot
[22:28] <Lunar_Lander> the master?
[22:28] <Lunar_Lander> no only the saw
[22:28] <fsphil> aah
[22:28] <Lunar_Lander> in the spheres it has batts
[22:28] <Lunar_Lander> actually something over 100 volts
[22:28] <Lunar_Lander> he got a special permit for that
[22:29] <Lunar_Lander> that's agamemnon: http://www.teamdelta.com/ag/ag-main.htm
[22:29] <jonsowman> evening all
[22:29] <Lunar_Lander> hi jonsowman
[22:30] <Lunar_Lander> fsphil The Master later fought in BattleBots too
[22:31] <Lunar_Lander> xD the prizes at RW USA 1994
[22:31] <Lunar_Lander> "At the end of the day, the prizes were awarded to the winners. All competitors got a tee-shirt, poster, brass Robot Wars plaque and some random boxes of software (I won Sim City 2000 for a Mac)."

[22:33] <Lunar_Lander> the electric lifter
[22:33] <Lunar_Lander> and the lexan whip
