[04:41] <shenki> ive been telling Darkside we should do a board using a STM32F

[06:31] <Darkside> ok, SD card logging works on all 3 boards i've built so far
[06:36] <griffonbot> Received email: James Coxon "[UKHAS] Fwd: [Balloon_Sked] KF4ZTI balloon launch this Saturday
[06:40] <eroomde> shenki: sorry, time zone fail
[06:40] <eroomde> erm, not looked into it properly
[06:40] <eroomde> probably one of the ST parts
[06:40] <Darkside> http://rfhead.net/gallery/2011-06-16_Assembled_MiniNut/
[06:40] <eroomde> infact i need soemthing with an external memory bus soon
[06:40] <Darkside> http://rfhead.net/gallery/2011-06-16_Assembled_MiniNut/DSC_4087.jpg
[06:41] <eroomde> Darkside: great job
[06:41] <eroomde> must be satisfying
[06:41] <Darkside> oh yeah
[06:41] <Darkside> esp now i'm sure the SD card stuff works
[06:41] <eroomde> a nice family photo :)
[06:42] <Darkside> MiniNut #1, 2 and 3
[06:42] <Darkside> :-)
[06:42] <eroomde> the next job will be to get a pelican case with custon foam slots to keep them all
[06:42] <Darkside> #1 = 151.3MHz, #2 = 434.650MHz, #3 = 144.39MHz, when the modules arrive
[06:42] <Darkside> now i need to make a payload box with interchangable antennas

[06:56] <fsphil> SMA :)
[06:57] <Darkside> mm
[06:58] <Darkside> i was thinking some kind of sturdy box base with bolts protruding
[06:58] <Darkside> and you screw on the radials
[06:58] <eroomde> yep
[06:58] <Darkside> i did a similar thing for a payload a while back, but the bolts weren't well secured, and broke on landing
[06:58] <eroomde> or you could just have 150mhz radials the whole time
[06:58] <Darkside> i think i'll be flying either 144.39MHz or 434.65MHz actually
[06:59] <eroomde> by which i mean, radials of sufficient length for 150 will only improve the ground for 434
[06:59] <Darkside> these boards may replace the existing horus payload
[06:59] <Darkside> eroomde: true
[06:59] <Darkside> and just have a SMA connector for the driven eement
[06:59] <Darkside> element*
[06:59] <eroomde> and then maybe just a bayonet active element
[06:59] <Darkside> or some other kind of connector
[06:59] <eroomde> or sam, yup
[06:59] <eroomde> sma*
[07:00] <eroomde> i don't know if a -40 celcius sma gets tighter or looser
[07:00] <Darkside> maybe just a bolt then
[07:00] <Darkside> i really want to make a payload with a cross-dipole antenna
[07:03] <fsphil> what advantage would they have?
[07:04] <Darkside> circular polarisation
[07:05] <Darkside> and it wouldn't have a null beneath the payload
[07:05] <Darkside> we already have a cross-dipole antenna on the DF truck

[08:18] <eroomde> anyone else into bread baking?
[08:19] <SamSilver> I am in a big way eroomde
[08:20] <SamSilver> I am in my ciabatta phase at the moment
[08:20] <eroomde> ah grand!
[08:20] <eroomde> awesome
[08:20] <eroomde> what kind of stuff do you like to do?
[08:21] <eroomde> it's sort of taken over from hopbby for me (my hobby has just become my job, so I need a new hobby)
[08:21] <SamSilver> went through a foccacia stage as well
[08:21] <SamSilver> lol
[08:22] <SamSilver> what you baking ?
[08:22] <eroomde> bit of a sourdough guy
[08:22] <SamSilver> I am using brewers yeast a lot at the mo
[08:22] earthshine (~mike@cpc2-orpi1-0-0-cust69.2-3.cable.virginmedia.com) got netsplit.
[08:22] Upu (~Upu@ubn.upuaut.net) got netsplit.
[08:22] <eroomde> a love a thin crispy blistered dark crust and big holey soft crumb. lots of oven spring
[08:23] <SamSilver> I spent a nearly a year getting the right type of bread to make the perfect slice of toast
[08:23] <eroomde> what did you settle on?
[08:24] <eroomde> see my sourdough quest is for the perfect cheese sandwhich. good sourdough with a bit of good local ham, good gruyere cheese gratings and some dijon mustard
[08:24] <eroomde> totally obscenely the stuff of life
[08:24] <SamSilver> brewers yeast, 20 hr first rise, 80% water to flour ratio,
[08:25] <eroomde> ah wow, totally after my own heart :)
[08:25] <SamSilver> 3 hr 2nd rise and straight into a hot casserole dish with lid @ 180
[08:25] <eroomde> long proofs and high hydration

[08:26] <eroomde> it's perfection
[08:26] <eroomde> with a glass of wine
[08:26] <SamSilver> wow slow down eroomde now she wants your addy
[08:26] <SamSilver> lol
[08:27] <SamSilver> i have yet to find a good gruyere here in SA
[08:28] <eroomde> i'm half french and dad is always over there with work so it's a bit easier
[08:28] <eroomde> though a good cheddar (montgomery i'm a big fan of) comes a close 2nd
[08:28] <eroomde> SamSilver: here's my 'turn-to' sourdough http://i.imgur.com/vLBPM.jpg
[08:29] <eroomde> always makes good sandwiches, and lasts a good few days in the bread bin

[08:29] <eroomde> ignore the packets of bakers yeast in the bg - i promise it's sourdough!
[08:30] <SamSilver> I was thinking the lack of air pressure at altitude might make up for yeast, so yeast-free bread at 95k ft might be a possibility!!
[08:30] <eroomde> now that's not a bad idea

[08:34] <eroomde> yeah rye breads are fun. i've not yet made one I've been really happy with
[08:34] <eroomde> working on it
[08:35] <eroomde> i have been playing with using guiness as the liquid
[08:35] <SamSilver> I have never gone further than 50% rye
[08:35] <eroomde> i'm after really rye-ish loafs to slice thinly to have with smoked salmon
[08:36] <eroomde> normally 100% rye is too rye-ish for me but in that context it works i think
[08:36] <SamSilver> guiness is a great idea - think I will give i a bash one day
[08:37] <eroomde> the fat helps :)
[08:37] <eroomde> croissants are the other thing i've been trying, but they're so much effort and so time consuming that i don't really have the time or patience to try them often
[08:38] <eroomde> they keep friends happy though
[08:38] <eroomde> http://i.imgur.com/1UqeF.jpg
[08:39] <SamSilver> the son in law is a bit of a croissant baker but they come out different ever time
[08:39] <eroomde> yep, i've been finding that. so temperature sensitive
[08:39] <SamSilver> nothing wrong with those
[08:40] <eroomde> and my starter is a bit schitzophrenic
[08:40] <eroomde> i think i don't give her enough of a routine to develop good habits
[08:40] <SamSilver> do you have a bitch?
[08:40] <eroomde> i'm single at the moment
[08:40] <eroomde> or do you mean the starter?

[08:41] <eroomde> i'm not sure you can get male starters
[08:42] <eroomde> well, if you can I imagine they're 200 years old and living in a pizzeria in naples
[08:42] <SamSilver> I am at work and no pics on PC will share with you at a later date
[08:42] <eroomde> and they're called claudio

[09:00] <SamSilver> done
[09:00] <SamSilver> that was great
[09:02] <eroomde> seems like he's got that lifestyle nailed. surfing in the morning, bread in the afternoon. they bake for 5pm - fresh bread for dinner, day-old for toast in following breakfast. quite a nice way of doing things and means you don't need to live crazy hours

[10:34] <Laurenceb> its certainly initialising to the correct attitude, and mostly ataging there
[10:35] <Laurenceb> on start up it accelerates down and stabilises a few hundered meters down, as the gps catches it
[10:35] <Laurenceb> then the attitude starts flipping upside down intermittently

[14:27] <Darkside> jesus fucking christ
[14:27] <Darkside> my supervisor has now suggested i make a DRM demodulator on a microcontroller

[14:27] <Darkside> SCARY.
[14:27] <shenki> Darkside: boards look good
[14:27] <eroomde> drm demodulator?
[14:27] <Darkside> eroomde: OFDM on HF
[14:27] <shenki> Darkside: are you putting the arduino bootloader on them?
[14:27] <Darkside> shenki: already have

[14:28] <shenki> cool
[14:28] <jonsowman> eroomde: http://www.flickr.com/photos/cuspaceflight/5841871071/in/photostream
[14:28] <Darkside> so as it stands, they work.
[14:28] <Darkside> i.e. they transmit, log to SD, etc
[14:28] <Darkside> all working fine

[14:28] <shenki> Darkside: do you have an accerometer?
[14:29] <Darkside> Dan-K2VOL: yes
[14:29] <Darkside> shenki: no
[14:29] <eroomde> what's thee the business around it?
[14:29] <SamSilver> my first time :-p
[14:29] <jonsowman> eroomde: that's how they supply it

[14:29] <shenki> Darkside: that's what we forgot :)
[14:29] <Darkside> shenki: i didn't bother
[14:29] <eroomde> gosh
[14:29] <eroomde> that's annoying
[14:29] <Darkside> if you can find a onewire accelerometer we could still do it >_>
[14:29] <shenki> Darkside: we could put one on the temp pins

[14:34] <eroomde> SamSilver: is that with brewers yeast?
[14:35] <SamSilver> yip
[14:35] <eroomde> cool
[14:35] <eroomde> might try that
[14:35] <eroomde> i have used ales to make a barm before. same idea i guess
[14:36] <SamSilver> I like brewers yeast and then use course sea salt with 50/50 honey and sucrose
[14:37] <SamSilver> the sea salt seems to make more interisting aroma
[14:37] <eroomde> i don't usually add any honey or sucrose, unless it's for a speciality bread
[14:37] <eroomde> i'm a bit of a salt, water, flour and noet else person :)
[14:38] <eroomde> yeah i've heard that about sea salt
[14:38] <eroomde> will give it a try
[14:38] <eroomde> soft water seems to be a good thing too
[14:40] <SamSilver> there are soooo many things to vary : time, temp at different stages ........
[14:41] <eroomde> kneading too
[14:41] <eroomde> kind of need to write each attempt down on a piece of paper as you loose track of everything otherwise
[14:42] <Randomskk> eroomde: or use git, a la https://github.com/scoates/owty/commit/f6519da85f6cfac00db8e58a9c71dd61233c97f6#owty.jpg :P
[14:42] <SamSilver> I like to make two identical loves that vary only in one way then compare
[14:44] <eroomde> tho often giving them the same conditions in the oven (or with sequential cooking) can affect things too
[14:45] <SamSilver> my perfect bread for toast http://imgur.com/69fOt
[14:46] <eroomde> that looks perfect
[14:46] <eroomde> nice and holey
[14:46] <eroomde> but it takes butter really well
[14:46] <eroomde> bet*
[14:50] <SamSilver> two the same but different - http://imgur.com/189MO
[14:50] <eroomde> pretty crazy oven spring on those
[14:50] <SamSilver> soooo any idea on a high altitude oven?
[14:50] <eroomde> well, i'm working on a wood fired oven
[14:50] <eroomde> but it's a bit heavy for ballooning
[14:51] <SamSilver> I would give up a body part for a wood oven
[14:52] <eroomde> well, trying to get one at the french house
[14:52] <eroomde> at 'home' could be a bit of a push
[14:52] <eroomde> i am looking for a house with one when i move to oxford but i also want to be in the city itself, i think the two are incompatible
[14:52] <SpeedEvil> I'm working on a tiny oven for reheating single petit-pain.
[14:52] <eroomde> but yes, wood oven and grand piano are my two life ambitions
[14:52] <SpeedEvil> And similar objects.
[14:53] <SamSilver> I use the barbecue for small loves but it has no heat retention as the lid is stainless steel
[14:53] <eroomde> yep
[14:53] <eroomde> i often do loaves in a big cast iron pot
[14:54] <eroomde> it's about the nearest i can get to a proper wood oven in a home kitchen
[14:54] <eroomde> gives you a big radiative thermal store, traps the steam for a nice crust
[14:55] Action: Laurenceb read that as radioactive thermal store
[14:55] <SamSilver> I have used cast iron pots as well, putting embers on top of lid
[14:55] <eroomde> ah neat

[15:00] <Laurenceb> hey at least it wnet better than copenhagen suborbitals
[15:00] <eroomde> 'general lessons' is interesting
[15:00] <eroomde> lots of parachute stuff
[15:01] <SpeedEvil> Argh - silly internets.
[15:01] <eroomde> drives home that parachutes are some of the toughest things to do in any flying system
[15:01] <SpeedEvil> I'm making a little oven - well - two of them. One will be for reflow, with a fast ramp rate, and good stirring of the air, the other will be for reheating sausage rolls and toast.
[15:02] <SpeedEvil> Ramp rates of mini ovens are crap, meaning I have to wait longer for food.
[15:02] <SpeedEvil> And they use lots of energy
[15:02] <eroomde> SamSilver: i used to have a decent electric fan oven at home
[15:02] <eroomde> in this new house we have a little gas thing
[15:02] <eroomde> it really sucks for bread
[15:03] <eroomde> nasty thermal gradients front to back and top to bottom
[15:03] <eroomde> and they don't like being saturated with steam either
[15:03] <SamSilver> mine has a slight left to right diff
[15:04] <SamSilver> I have tried many methods for steam
[15:04] <eroomde> i have a large (~ 10kg) granite slab that i pre-heat to 240C which helps a lot, if i'm doing something bigger than the cast iron pot can handle
[15:04] <eroomde> and i do like big loaves
[15:04] <eroomde> but i need a decent cover to trap the steam
[15:05] <SamSilver> 10kg granite on top or below?
[15:05] <eroomde> below
[15:05] <eroomde> dough goes directly on it
[15:05] <eroomde> gives lovely oven spring
[15:05] <SamSilver> get another 46 of them granite stones and buile an outdoor oven
[15:06] <SamSilver> build
[15:06] <eroomde> working on it!
[15:06] <eroomde> my gran's old house is by the seaside here in england
[15:06] <eroomde> we're doing it up
[15:06] <SpeedEvil> 240c?
[15:06] <eroomde> really pushing for a bread oven in the bag garden, nice brickwork with a shell mosaic on the outside
[15:06] <eroomde> celcius
[15:06] <SpeedEvil> Doesn't that burn the dough when you put it on?
[15:06] <eroomde> nope
[15:07] <eroomde> there's so much water in these doughs
[15:07] <SpeedEvil> I suppose granite has a fairly poor thermal conductivity
[15:07] <eroomde> it does however have a nice big thermal mass to keep duming heat into the base and middle of the bread
[15:07] <eroomde> dumping*
[15:07] <eroomde> i do often get a fairly crispy base, but still never black
[15:07] <SamSilver> http://imgur.com/ottrJ red wine,macadamia nut and fig loaf
[15:07] <eroomde> but i like nice bold colourfull bakes :)
[15:07] <SpeedEvil> Neat.
[15:08] <eroomde> just like SamSilver's link above
[15:08] <eroomde> just a lovely free-form rustic loaf
[15:08] <SpeedEvil> My breadmaking is somewhat handicapped by tesco value flour.
[15:08] <eroomde> SpeedEvil: http://bewitchingkitchen.files.wordpress.com/2010/11/tartine1.jpg
[15:08] <eroomde> that kind of thing
[15:08] <eroomde> long slow proof so lots of the starches get broken down into simpler sugars
[15:09] <eroomde> so when you bake you get these wonderful shades from the caramelisation
[15:09] <SamSilver> a new organic mill has started up about an hour from me great strong white and tasty ww
[15:09] <eroomde> and loads of steam to give a thin, blistered, really crispy crust
[15:09] <eroomde> i consider that perfect bread
[15:09] <eroomde> SpeedEvil: tesco's unbleached organic stuff is really not bad, infact
[15:09] <eroomde> i've been nicely surprised by the flavour
[15:09] <SpeedEvil> Neat.
[15:10] <SpeedEvil> Yeah - I mean more the actual value white
[15:10] <SpeedEvil> It's not bad with a little sourdough flavour.
[15:11] <SpeedEvil> But it's nothing exceptional.
[15:11] <eroomde> sourdough can do wonders :)
[15:11] <eroomde> i'm going to experiment with spelt flour SamSilver
[15:11] <eroomde> half spelt and strong white sourdough
[15:11] <eroomde> the flavour is really interesting
[15:12] <SpeedEvil> Spelt is.
[15:12] <SamSilver> I have never managed to my hands on any
[15:12] <eroomde> tesco have it
[15:12] <SpeedEvil> I'm wondering about ordering some gluten, to play with.
[15:12] <eroomde> tho of course that's no help to you :)
[15:12] <eroomde> it's apparently a lot less bloating that wheat too
[15:12] <eroomde> but the gluten in it is all funky
[15:12] <eroomde> will need some research
[15:13] <SamSilver> no Tesco here
[15:13] <SpeedEvil> I can in principle afford it at the moment, but I'm trying to _really_ hammer down on the budget at the moment to pay for energy saving and other long-term-cost saving measures.
[15:13] <SpeedEvil> And stupid accidents involving glass. :/
[15:13] <eroomde> why do you need capital for energy saving - eg installing solar heating?
[15:14] <SpeedEvil> Insulation is unfortunately moderately expensive, for example.
[15:14] <eroomde> http://blogs.sfweekly.com/foodie/tartinebread1.jpg
[15:14] <SpeedEvil> At least on the budget I'm on.
[15:14] <eroomde> that's just so bloody perfect
[15:14] <eroomde> it's bread with an old soul.
[15:15] <SpeedEvil> That looks lovely.

[15:16] <Upu> anyway to fix that ?
[15:16] <Dan-K2VOL> From my experience with wikis in general, copy the wikicode and delete the old page and make a new one
[15:16] <eroomde> SamSilver: the nice thing about the tartine book is that the rear 1/3rd are recipes for day-old bread

[15:19] <eroomde> breadsong is a close second to chopin for me
[15:19] <SamSilver> never heard it called that "breadsong" luv it!
[15:19] <eroomde> hmm, that's the wankiest thing i've said so far this year
[15:20] <eroomde> i must keep this in check
[15:20] <Randomskk> haha
[15:20] <Dan-K2VOL> Lol
[15:20] <eroomde> but yeah, nothing like breadsong when you pull it out of the oven

[15:21] <jonsowman> Upu: just delete everything on the page
[15:21] <eroomde> SamSilver: right, i'm definitely baking this evening
[15:21] <eroomde> will have a go at a rye-and-wholemeal sourdough
[15:22] <Upu> bingo thx
[15:22] <SamSilver> I will be starting a 20hr sourdough loaf aswell
[15:22] <SamSilver> with a touch of rye 20% maybe
[15:23] <eroomde> i usually get the rye note from just 5%
[15:23] <eroomde> and maybe 20% WW
[15:23] <eroomde> the rest a medium strength white
[15:23] <eroomde> i find strong white can make it a bit chewy and tough
[15:23] <SamSilver> rye for final dusting
[15:23] <eroomde> i quite like a softer, more pillowy crumb
[15:23] <eroomde> so cutting strong with plain flour tends to work out
[15:24] <SpeedEvil> Hence why I'm wondering about gluten - it's quite inexpensive - 2.50/Kg
[15:25] <SamSilver> i have been adding chickpeas ground up to my thin foccia
[15:25] <eroomde> how is that turning out?
[15:26] <eroomde> i've sort of wanted to make a humous-ey dough
[15:27] <Laurenceb> hmm i seem to be in #bread
[15:27] <SamSilver> it seems to make them puff up pitta style
[15:27] <SamSilver> adds nice nutty flavour
[15:27] <SamSilver> maybe we can swop a recipe or two soon
[15:28] <eroomde> for sure
[15:28] <SamSilver> but for now I am off home finished work over an hour ago
[15:28] <Laurenceb> adding a nutty flavour... surely thats my job
[15:28] <SamSilver> wife on phone

[16:44] <cuddykid> Hi all
[16:48] <cuddykid> has there been any work done recently on an autonomous return vehicle? Been looking through wiki and the projects seem to be on hold or dead
[16:49] <Upu> probably legatliy
[16:49] <Upu> its a UAV
[16:49] <Upu> and you can't do those I understand
[16:50] <russss> IIRC someone did a flight with a steerable rogallo parachute, but it didn't work too well.
[16:50] <cuddykid> Upu, that's a shame if correct :( however, I'm sure they were planning one
[16:52] <cuddykid> been looking at the diydrones IMU autopilot.. can follow 3D waypoints and all of that fancy stuff... If I could shrink the payload size down to putting it in the body of a big glider then it could possibly work
[16:52] <SpeedEvil> Laurenceb did the rollago
[16:52] <SpeedEvil> It failed for boring reasons - mechanical issues
[16:52] jasonb (~jasonb@12.201.129.162) joined #highaltitude.
[16:53] <SpeedEvil> It seemed in principle to be likely to work if it was retried, but never was.
[16:53] <cuddykid> I just like the idea of sitting back and waiting for the payload to come back! Also.. avoids the tree issues that seem to be occurring a lot recently!
[16:54] <SpeedEvil> It only avoids the tree issues if it picks a return route without trees.
[16:54] <cuddykid> yeah lol, that would be unlucky if it flew straight into a tree!
[16:54] <Dan-K2VOL> I'd ike to see someone do a quadcopter return payload :-P
[16:55] Action: SpeedEvil wishes he had his UAV done.
[16:55] mixio (~mixio@ppp046177127183.dsl.hol.gr) left irc: Ping timeout: 240 seconds
[16:55] <SpeedEvil> http://www.mauve.plus.com/test.png is as far as I've got - and a box of bits though.
[16:56] <Dan-K2VOL> Actually UAVs are legal above controlled airspace, perhaps you just need to have some massive inflated wings above 60kft to steer to a point that has a predicted drift landing somewhere nice
[16:56] <cuddykid> Dan-K2VOL been looking at the quadcopters, they are soo awesome!
[16:57] <cuddykid> nice SpeedEvil
[16:58] <cuddykid> problem is the cost.. it looks around £500 at least to get a quadcopter up and running
[16:58] <SpeedEvil> The nice bit about this is that you can clip a pair of wings to it, and it's a 'conventional' UAV
[16:59] <Dan-K2VOL> oh hey, you know what might really help if you could detect imminent tree impact? cutting off the support ropw at about 10 meters above the trees, so you have a little speed to bash through all the branches and get to the ground.

[17:01] <russss> parachutes, as we have determined, are a bit of a pain
[17:01] <russss> if you want to try and do anything fancy
[17:01] <russss> like deploy them. Or steer them.
[17:02] <eroomde> a nasa engineer desicribed parachute deployment, in a recent conference talk, as a 'bounded random event'
[17:02] <eroomde> which sums it up nicely
[17:02] <eroomde> jonsowman: yo
[17:02] <cuddykid> haha eroomde
[17:03] <eroomde> i was unfortunely commited to helping churchill casino do some moving. is meeting still going?
[17:03] <eroomde> hi cuddykid
[17:03] <cuddykid> yeah, I think a big glider or quadcopter would be way forward that activates when below controlled airspace
[17:03] <cuddykid> hi eroomde
[17:04] <Dan-K2VOL> or heck, go the route of the MSL lander Curiosity, retro rockets to steer around and a winch!
[17:04] <eroomde> utterly binkers
[17:04] <Dan-K2VOL> Hehe
[17:04] <eroomde> bonkers*
[17:05] <BrainDamage> or, add few co2 capsules, and add inflatable bumpers?
[17:05] <eroomde> it's just so they can land at higher altitudes
[17:05] <eroomde> airbags also very difficult!
[17:05] <eroomde> but much easier for a 3kg payload
[17:05] <BrainDamage> not for full height fall, you still keep the chute, but at fixed height you inflate the airbag & detach the chute
[17:06] <jonsowman> eroomde: we're all still here if you're free now
[17:06] <russss> eroomde: well, the interesting thing is that there's only ever been one parachute failure in a manned spacecraft re-entry, so I guess it's possible to do right
[17:06] <BrainDamage> so you ensure the kinetic energy is limited, and you have sufficient to bounce off a tree
[17:06] <eroomde> people here have been drinking too much jpl cool-aid
[17:06] gartt_ (~gart@ip68-0-205-209.ri.ri.cox.net) left irc: Read error: Operation timed out
[17:06] <russss> yeah, the reason people use parachutes is they're a lot lighter than rockets...
[17:06] <russss> and I suppose probably more reliable.
[17:07] <russss> certainly less things to go wrong

[17:08] <cuddykid> also, some may know on here.. I was looking at the JP aerospace peoples website and it looks incredible. But, how do they plan on maintaining a certain position and altitude for their "dark space station"?!! Only thing I can think of was a tether or fans.. was going to email but thought i'd ask here 1st :)
[17:08] <eroomde> and me to his right!
[17:08] <Dan-K2VOL> Haha nice eroomde!

[17:09] <eroomde> a was a bit foggy by that point in the morning
[17:09] <eroomde> but the jpl guys were still going strong.
[17:12] <russss> JP Aerospace are certifiably insane
[17:12] <eroomde> the right sort of insane though, I think
[17:13] <russss> yeah
[17:13] <cuddykid> yeah, incredible plan.. need people to take over now nasa's funding has been cut
[17:13] <eroomde> that might be pushing it alittle
[17:13] <cuddykid> lol
[17:13] <eroomde> but it's a sort of bold plan in the way that reaction engines is bold

[18:56] <cuddykid> ahh cool, thanks
[18:56] <SpeedEvil> make a board = design a board, and get someone else to make it - there are fairly inexpensive services. Or buy a 'breakout' board with a pre-soldered one.
