[07:17] <UpuWork> someone launch this weekend pls
[07:17] <cuddykid> they're going to turn our electricity off here until 4pm :( boooooo
[07:17] <UpuWork> need to test my pikey antenna
[07:17] <number10> what is the antenna UpuWork ?
[07:17] <cuddykid> UpuWork: was going to but winds are not good - hopefully next week
[07:18] <UpuWork> A colinear I made from some old TV coax and £3 worth of dowel and plastic tube from B+Q
[07:18] <UpuWork> part of my "can you build a tracking station for HAB for < £25 all in" project
[07:18] <number10> sounds good
[07:19] <UpuWork> http://imgur.com/a/1bqjM#0
[07:19] <UpuWork> complete with wine "cork" the end
[07:19] <UpuWork> was cheap wine we'd been given eroomde don't hate me
[07:20] <UpuWork> I used it for cooking
[07:20] <Darkside> UpuWork: you should be testing it with a known receiver though
[07:20] <Darkside> not the SDR dongle
[07:20] <UpuWork> well thats the plan Darkside
[07:20] <UpuWork> I can switch between the 817 and SDR fairly quickly
[07:20] <Darkside> what kin of coax was that?
[07:20] <number10> well it looks good UpuWork - you never know it may be near as good as your watson
[07:20] <UpuWork> RG59 I think
[07:20] <Darkside> oh
[07:20] <Darkside> instant 1.5:!
[07:20] <Darkside> 1.5:1
[07:21] <UpuWork> 75 ohm
[07:21] <Darkside> yes
[07:21] <UpuWork> better for reception
[07:21] <Darkside> eh?
[07:21] <UpuWork> 33 ohm = better for xmit
[07:21] <Darkside> wait
[07:21] <UpuWork> 75 ohm better for receive
[07:21] <Darkside> so just the antenna is made with 75 ohm
[07:21] <UpuWork> so somewhere in the middle is 50 ohm
[07:21] <UpuWork> yes
[07:21] <Darkside> and it has a 50 ohm input ompedance?
[07:21] <Darkside> oh phew
[07:21] <Darkside> i thought you were running RG59 back to the radio
[07:22] <UpuWork> the input on the SDR is 75 ohm
[07:22] <Darkside> thats debatable
[07:22] <UpuWork> I am running 75 ohm back to the radio
[07:22] <Darkside> i'm actually not sure that it is
[07:22] <number10> I like the pink tape on it
[07:22] <Darkside> esp with the e4000
[07:22] <UpuWork> I'm not going for perfection
[07:22] <UpuWork> just a recievable signal
[07:22] <Darkside> also it means with your 817 you'll get an instant 1.5:1
[07:22] <Darkside> mm
[07:22] <UpuWork> on the plus side it did pick up all the QRM on 434.075
[07:22] <UpuWork> so somethings working
[07:23] <Darkside> if you're going to use the amp with it, make sure you have 50 ohm cable and stuff
[07:23] <UpuWork> oh not transmitting
[07:23] <Darkside> thats not what i mean
[07:23] <UpuWork> oh your amp
[07:23] <Darkside> i mean if you want to put one of the HABAMPS in the tube as a masthead amp
[07:23] <UpuWork> no not doing that
[07:23] <UpuWork> sorry I'm slow this morning not had my coffee yet
[07:23] <Darkside> would work well though :-)
[07:24] <UpuWork> this is just a test to see if you can do it with a £14 dongle and some old coax
[07:24] <Darkside> but that amp wants a 50 ohm input and output impedance
[07:24] <Darkside> mm
[07:24] <UpuWork> £14 I might add which are going up all the time
[07:24] <Darkside> where did you get the antenna design?
[07:24] <UpuWork> amp will be going on the watson
[07:24] <UpuWork> which is all 50 ohms
[07:25] <Darkside> i wouldn't put the amp on an antenna which can be used well for TX
[07:25] <UpuWork> http://www.srgclub.org/CollinearAnt-HomeBrew.html
[07:25] <Darkside> else it won't be usable for TX at sll
[07:25] <UpuWork> no my plan is yagi -> 817
[07:25] <UpuWork> colinear -> habamp -> sdr
[07:25] <UpuWork> when I get the Yagi up
[07:25] <Darkside> ok
[07:26] <UpuWork> the home made thing is just a test
[07:26] <Darkside> that design is for 50R coax
[07:26] <Darkside> are you sure it works properly with 75R?
[07:26] <Darkside> actually you can test that
[07:26] <Darkside> use a SWR meter and see if you get 1.5:1
[07:27] <UpuWork> I spoke to Robin at the club and he suggested 75ohm would be better for a recieve only
[07:28] <Darkside> ok not sure about that
[07:28] <UpuWork> V=IR more R = more V
[07:28] <Darkside> i'm just not sure if the design relies on 50R coax or not
[07:28] <UpuWork> well we'll see
[07:28] <Darkside> i'm sure it'll do something
[07:28] <Darkside> its just it probably isn't the optimal design
[07:28] <Darkside> RG58 isn't hard to come by
[07:28] <UpuWork> no I'm sure its far from optimal
[07:28] <UpuWork> its version 1
[07:29] <Darkside> mm
[07:29] <Darkside> i might try making one using RG58
[07:29] <UpuWork> the dowel and tube were £3

[08:38] <WillDuckworth> hey dave - how's pi-hab going?
[08:44] <daveake> Just wondering what to actually do with it :)
[08:44] <daveake> I'll stick it in the freezer soon to see how it copes
[08:45] <daveake> Just wondering whether to fly it as it stands or try and do add picture telemetry
[08:45] <daveake> -do
[08:49] <gonzo_> it will get forgotten in the freezer and the sticker saying what it is will fall off. So when you are running the freezer down, you will end up with a greater surpise than usual, when it defrosts
[08:49] <gonzo_> rather than the usual, is this pie chicken or apple type delema
[08:52] <daveake> Actually, with the power that thing uses, it's more likely to melt everything around it!

[09:18] <gonzo_> upuwork, earlier chat on coax: I often use sat tv (CT100) coax for the RX feeders. Even though the preamps have 50R outputs, the mismatch is going to have little effect aftre the amp. And that cable is quite low loss for the price.
[09:19] <gonzo_> some preamps can be a bit touchy when terminated wrong though, and can oscillate, depends on the design.

[09:58] <eroomde> the particular notebook brand i like (spiral bound hard cover black n' red squares) is £12 from amazin before p&p
[09:58] <eroomde> and 4.99 from a stationer on ebay inc p&p
[09:58] <eroomde> so basically with p&p amazon costs 3x as much
[10:03] <SpeedEvil> Oh wow!
[10:03] <eroomde> i know right?
[10:03] <SpeedEvil> Does it have a plasticised cover, so it's moisture resistant?
[10:03] <eroomde> yes
[10:03] <SpeedEvil> Awesome.
[10:03] <eroomde> helps prevent the tears of joy from ruining my ideas as i jot them down
[10:04] <SpeedEvil> In the same vein, I'm slightly annoyed I can't get the pentel 'shaker' - which was a mechanical pencil that was advanced by shaking. - in the format I'd like.

[10:21] <nick_> I'd be an awesome part of that business, I'm always stealing my supervisors pens
[10:22] <daveake> I reckon it'd earn me at least 60,000 Altairan dollars

[10:29] <UpuWork> I have one of these : http://www.ebay.co.uk/itm/Rotring-600-Mechanical-Pencil-0-5mm-Black-/271006214894?pt=UK_BOI_Office_Office_Supplies_Stationery_ET&hash=item3f193aaaee
[10:29] <UpuWork> had it for years
[10:29] <eroomde> yeah BrainDamage said he has the rotring 600
[10:29] <eroomde> i am super close to treating myself actually
[10:29] <eroomde> to a rotring isograph pen
[10:29] <eroomde> or 2
[10:29] <eroomde> i used one once, the nicest thing for techy drawing i have every used
[10:29] <UpuWork> bought mine 20 years ago and its worn down to the brass but stillworks fine
[10:30] <eroomde> the isograph 0.5 makes really nice crist black lines without denting the paper. it lets you fill in areas but still get smooth solid blackness, if you see what i mean
[10:30] <eroomde> lemme fine an example
[10:31] <eroomde> http://2.bp.blogspot.com/_buMt-wZ5lUw/R1hiDUfWB9I/AAAAAAAAAhc/27oAVJ5k680/s400/rotring+and+moleskine.jpg
[10:31] <UpuWork> my dad was a Draughsman ...
[10:32] <SpeedEvil> Was he excluded by computers?
[10:32] <eroomde> ah cool
[10:32] <eroomde> so yes, i am mega close to trating myself to this: http://www.amazon.co.uk/Rotring-Isograph-College-Mechanical-S0699380/dp/B000SHPZQY
[10:32] <UpuWork> he retired just as they were coming in
[10:32] <UpuWork> never go to grips with them
[10:32] <UpuWork> he has some surgical looking instruments
[10:33] <UpuWork> and I have his fathers (also a Draughtsman) slide rule which one day I'm going to work out how you use and land on the moon with it
[10:33] <eroomde> :)
[10:34] <eroomde> i re-bougth the calculator i had when i was 10-15
[10:34] <eroomde> i.e. as far as GCSEs
[10:34] <SpeedEvil> If bits land on the moon, you were sliding it too fast.
[10:34] <UpuWork> FX81 ?
[10:34] <eroomde> my fingers are trained with it
[10:34] <eroomde> fx-992s
[10:34] <eroomde> it's infront of me
[10:34] <UpuWork> i got one for doing the full exam
[10:34] <eroomde> i rate it so much above computer calculators
[10:35] <UpuWork> but yeah I had something similar
[10:36] <daveake> gonzo_ Glad someone noticed :D
[10:36] <nick_> Slide rules are pretty simple.
[10:36] <fsphil> I need a calculator. for being massivly powerful systems, the calculator programs on PCs are rubbish
[10:36] <BrainDamage> I would love instead a pocket calculator running "qalculate" the software, it's one if not the best calculator app I've seen
[10:36] <eroomde> right i have ordered those isograph pens
[10:36] <eroomde> now i will get into space
[10:36] <eroomde> one nice sketch at a time
[10:36] <UpuWork> lol
[10:36] <nick_> fsphil: just use python
[10:37] <eroomde> nick_: nah see it's silly
[10:37] <nick_> Why?
[10:37] <daveake> I have an old HP 28S. It's smarter than I am.
[10:37] <eroomde> with a good calculator you've got an answer before you've had a chance to type ipython into a prompt
[10:37] <fsphil> plus it's nice just having a small calculator
[10:37] <fsphil> you're not always near a computer
[10:37] <UpuWork> heh check this 1 sec I'll take a pic
[10:37] <Darkside> i still have a TI-89 floating around somewhere
[10:37] <eroomde> and i increasinly resent computers when trying to think and design stuff
[10:37] <Darkside> i had a TI-83, but it died
[10:37] <eroomde> they are too distracting
[10:38] <fsphil> so true eroomde
[10:38] <eroomde> i want a calulcator and a pience of paper and a pen
[10:38] <daveake> I usually use a YI-52. Basic scientific with hex, so it's all I need
[10:38] <daveake> TI-52
[10:38] <fsphil> if I get one it has to have Hex
[10:38] <UpuWork> https://www.dropbox.com/s/xhb5jgfbqlgoqsj/2012-06-29%2011.38.01.jpg
[10:38] <fsphil> the computer kind, not the magical spell
[10:39] <eroomde> the fx-992s i have does hex
[10:39] <eroomde> i don;t think it's a particularly outstanding calc though compared to the others in that range
[10:39] <eroomde> but it's the one i know
[10:39] <nick_> eroomde: only because you don't have python running all the time...
[10:39] <fsphil> that reminds me of the old Commodore calculators UpuWork
[10:39] <eroomde> nick_: there is that true
[10:39] <UpuWork> it is an old Commodore one :)
[10:39] <eroomde> but it still involves being near the computer
[10:39] <fsphil> that'll be why lol
[10:39] <daveake> Blimey UpuWork. If it was any older it'd have Nixie tubes :p
[10:39] <UpuWork> 9D-25
[10:40] <eroomde> lol UpuWork
[10:40] <nick_> Or use google
[10:40] <UpuWork> 1976
[10:40] <eroomde> wolfram alpha is pretty useful
[10:40] <nick_> There is just no reason to use those horrible clicking calculator programs.
[10:40] <eroomde> it can do nice things now like 'pressure at 42km'
[10:40] <daveake> I had a Sinclair Scientific. That was a laugh
[10:41] <BrainDamage> nick_: if you like python, try reinteract
[10:41] <daveake> http://en.wikipedia.org/wiki/Sinclair_Scientific
[10:42] <gonzo_> think I have an old sinclair type (not an original) basic calc with LED diasplay somewhere
[10:48] <daveake> Without wishing to bring us back on topic :-), I have dl-fldigi set up for rig control (using RigCAT) and if I click on the QSY button it does change the rig (FT817) frequency to centre the the rtty bars around 1kHz. However it doesn't keep them centred automatically. i.e. if they drift it doesn't re-tune to keep them centered. What have I missed?
[10:49] <UpuWork> there is an option buried somewhere to turn it on
[10:49] <daveake> I guessed, but it's buried enough that I haven't found it :(
[10:49] <Upu> dl-client
[10:49] <Upu> configure
[10:50] <Upu> under enable tab

[11:08] <eroomde> so we're going to get our rocket fired today, somehow
[11:08] <eroomde> currently dissolving an estes motor into a solvent to make a slush, which we will paint on the inside of the combustion chamber
[11:08] <eroomde> layer, let it dry, layer, let it dry, layer, let it dry
[11:09] <SpeedEvil> :)
[11:09] <eroomde> if that thing doesn't get enough thermal energy into the chamber then we've had it
[11:09] <WillDuckworth> sounds fun eroomde
[11:09] <SpeedEvil> eroomde: Do you have the appropriate fireworks factory licence for manufacturing fireworks? :)
[11:09] <eroomde> it's a bodge solution but it would be nice to finish the week with a sucessful firing, before we start machining a hot-gas torch igiter
[11:09] <eroomde> SpeedEvil: have a guess
[11:10] <SpeedEvil> Heat the chamber bright yellow before injecting?
[11:11] <eroomde> cheating
[11:11] <eroomde> not that this isn't
[11:11] <SpeedEvil> Or this is an excellent excuse to buy that large pulsed laser you've always wanted, that you can point up the exhaust from 50m away.
[11:11] <eroomde> we'll do the same as wednesday again, putting a little pyrogen charge up through the throat
[11:12] <eroomde> but it should hopefully get the entire chamber liner going if it's coated with this special sauce, before the igniter gets pooped out of the throat
[11:12] <eroomde> the other additives to the special sauce are aluminium powder and iron oxide
[11:12] <eroomde> it's better than any bbq sauce you'll ever have
[11:12] <SpeedEvil> Good luck!

[11:28] <kokey> I've got some of the dave's sauces at home
[11:29] <kokey> tesco still stocks the insanity sauce, but I prefer the ghost pepper sauce
[11:29] <kokey> the ghost pepper one is even hotter, but not by much, but it has a lot more nice flavour
[11:30] <kokey> I've also got a bunch of the pete's sauces, like dragon's slayer, dragon's blood and satan's shit
[11:31] <gonzo_> one of the guys here used to make his own sauces and pass them around to the hedonists
[11:31] <gonzo_> but as they got hotter he started to run out of expletive names for them
[11:31] <kokey> i've made a couple, by buying fresh habanero chillis and nagas, and chopping them up in the blender with a bit of salt, garlic and vinegar
[11:33] <gonzo_> scotch bonnet minced were the nastiest
[11:33] <gonzo_> that was Graham's C**tingly hot
[11:33] <gonzo_> you can't get much worse, name or heat
[11:35] <kokey> habanero, scotch bonnet, same thing
[11:35] <kokey> about a third as hot as the really hot stuff
[11:36] <kokey> however, when they are fresh, because they are so fleshy, they get you really good
[11:37] <kokey> but for fun add some naga peppers which are hotter

[14:16] <nick_> Or don't use define...
[14:21] <UpuWork> hi LBCran
[14:22] <LBCran> So, someone linked me DAP1919 as the form to use in the university society for this balloon...
[14:22] <LBCran> that isnt right, is it?
[14:22] <LBCran> Since found this on UKHAS http://ukhas.org.uk/_media/general:met_balloon_release_application_jan_05_.doc
[14:23] <daveake> DAP1919 is for captive balloons
[14:23] <UpuWork> that one linked is the one I used but the mail address on it is wrong
[14:23] <LBCran> I was told by my helpful colleague it could be for both... :/
[14:23] <LBCran> the email address?
[14:24] <gonzo_> I updated the wiki text with the correct address
[14:24] <UpuWork> he did
[14:24] <daveake> We had someone here before claiming that it was just fine to use the DAP1919.
[14:24] <daveake> Same person flew without a NOTAM ...
[14:25] <LBCran> ah very good. I'll use that address later.
[14:25] <LBCran> gonna go pick up an OS map from a lecturer I know who has one, brb.
[14:26] <nick_> What happens if you fly without a NOTAM?
[14:26] <UpuWork> you break the law
[14:26] <nick_> It's a legal requirement, no?
[14:27] <nick_> So if you get caught there's a fine?
[14:27] <UpuWork> I'm not a lawyer
[14:27] <UpuWork> I'm sure its breaking some air navigation order
[14:27] <UpuWork> and if something bad were to happen you'd be sued out of existance probably
[14:28] <UpuWork> just do it properly
[14:29] <nick_> Did anyone report him?
[14:29] <UpuWork> i don't believe so
[14:29] <UpuWork> I think there have been a number of launches done without NOTAMS but I really wouldn't advise it
[14:30] <UpuWork> only takes one person to screw it up for the rest of us
[14:30] <nick_> It could be something that is essentially self policing, since otherwise it's ineffective.
[14:30] <nick_> YEah, that's what I was thinking.
[14:31] <nick_> So I thought that someone may have reported it to send the message that it's nothing to do with the community who do things by the book.
[14:31] <UpuWork> chances are it will go unnoticed
[14:31] <UpuWork> possibly
[14:32] <fsphil> I don't believe there's much going on >10km that isn't noticed by someone
[14:32] <UpuWork> I know of a payload that was picked up on raf fylingdales Ballistic Missile Early Warning Station
[14:32] <nick_> :S
[14:32] <nick_> "Holy shit, the russians fired a super slow missile at us!"?
[14:33] <fsphil> they fired it in 1967
[14:33] <fsphil> only just getting to us now
[14:33] <nick_> Didn't the Japanese do that to America in WW2 though?
[14:34] <fsphil> yea, balloon bombs
[14:34] <nick_> Send some balloons with bombs over the pacific.
[14:34] <fsphil> there's a good video on that produced by the US army

[14:35] <nick_> Like send a balloon the randomly parachutes toys down to earth

[14:36] <nick_> It could be awesome to drop some alien toys.
[14:37] <nick_> Let some kid somewhere think his toy came from space.
[14:37] <nick_> Although you'd kinda have to drop it somewhere fairly populated.
[14:38] <nick_> Could be a neat alien prank if you did it at night and attached some lights

[15:18] <WillDuckworth> hey fsphil - what's this HaTTY stuff?
[15:19] <kokey> HaTTY... sounds interesting
[15:19] <fsphil> it's a kind of ascii on a diet
[15:19] <fsphil> since we mostly transmit numbers, makes numbers smaller (4 bits)
[15:20] <WillDuckworth> 4 bits instead of 7 or 8 then?
[15:20] <kokey> what decodes it?
[15:20] <kokey> using error correction?
[15:20] <fsphil> dl-fldigi should, if it works well enough
[15:20] <fsphil> no fec yet, but there will be
[15:20] <fsphil> although that will make it 8-bit again :)
[15:21] <zyp> why not just go binary with FEC if you are going to use something else than ASCII?
[15:21] <fsphil> this is simpler to hack into fldigi
[15:21] <WillDuckworth> hmmm - looks interesting :)
[15:21] <zyp> that sounds like a bad excuse to me
[15:21] <fsphil> (for me anyway - I'm sure you'd have no bother making a better mode :)
[15:22] <fsphil> just a little experiment so far
[15:24] <zyp> IMO the only reason for using text based formats is the simplicity/accessability of it, and you kind of defeat that purpose when you go and make custom text encodings
[15:25] <fsphil> the format we use for our strings is pretty flexible
[15:25] <fsphil> would be nice to keep that, just make it a little sturdier
[15:26] <zyp> and what prevents you from doing something similar with binary fields?
[15:26] <zyp> syncword, bitmask that tells what fields are included, then list of fields and checksum, then FEC on top of that

[17:40] <eroomde> there's plenty of work to do though
[17:40] <eroomde> it was running a bit fuel rich at the end as the oxidiser valve is faster than the fuel valve when it spools down
[17:40] <eroomde> and went a bit unstable, sounding like a tommy gun
[17:40] <eroomde> need to put rates into the control look tis all
[17:41] <eroomde> also we made a new igniter using a neon sign transformer to make big arcs
[17:41] <eroomde> but the data logger does not like it arcing one little bit
[17:41] <eroomde> my special Rocket BBQ Sauce worked :)
[17:42] <eroomde> though it burned a bit quick

[19:21] <Lunar_Lander> hi nigelvh
[19:21] <Lunar_Lander> today I had to leave behind a problem at the lab
[19:21] <nigelvh> Yeah
[19:21] <Lunar_Lander> why does the BMP085 show that I am 7000 m below sea level
[19:21] <nigelvh> Was it named Spot?
[19:21] <Lunar_Lander> xD no
[19:21] <nigelvh> Probably math
[19:22] <Laurenceb_> because maths
[19:22] <Lunar_Lander> yea
[19:22] <daveake> Either that or Germany has gone to hell after last night's result
[19:22] <nigelvh> Assuming all your bits are in order.
[19:22] <eroomde> just seen on you've been framed, a todler singing 'I really love to spell! S-E-P-L Spell!! I really love to spell! S-E-P-L Spell!'
[19:23] <Lunar_Lander> XD!
[19:23] <Lunar_Lander> I made my thoughts about LEDs too
[19:23] <Lunar_Lander> I think I'll put a green, yellow and red LED on my board
[19:24] <Lunar_Lander> green is wired to the 3.3V line, so that goes on when the board has power
[19:24] <eroomde> just be sure you don't mind having 20mA constantly being used by an LED
[19:24] <nigelvh> As usual don't forget the resistors
[19:24] <Lunar_Lander> yea to both
[19:24] <Lunar_Lander> I think I told how I fried an LED with a 150 Ohm resistor at 5 V
[19:24] <nigelvh> The LEDs do add up significantly
[19:25] phirsch (~phirsch@xdsl-89-0-152-46.netcologne.de) left irc: Ping timeout: 246 seconds
[19:25] <Lunar_Lander> yea
[19:25] <nigelvh> I was fiddling with the powersave modes on an Atmega 1280 and saved a TON by shutting off all the leds and defining the outputs.
[19:25] <Lunar_Lander> the idea was to have an indicator on the ground
[19:25] <Lunar_Lander> that the red LED goes on, or flashes if there is no lock or another error
[19:26] <Lunar_Lander> so that we can see that on the launch pad so to speak
[19:26] <nigelvh> Yeah, in my flights I've got more than enough power, so I leave the LEDs on. In this instance I wanted to run a board and a transmitter for about a week off a battery, so I had to save some power.
[19:27] <Lunar_Lander> yea
[19:27] <Lunar_Lander> I had like an idea for different error modes
[19:27] <Lunar_Lander> like when no lock, yellow is on steady and red flashes
[19:27] <Lunar_Lander> when lock, yellow will flash and red goes out
[19:28] <Lunar_Lander> when there is corrupt sensor data, yellow and red will flash
[19:28] <Lunar_Lander> or so
[19:28] <nigelvh> Yeah. Like you can see here, I've got a pile of LEDs for status. https://k7nvh.com/wordpress/wp-content/uploads/2012/02/photo.jpg
[19:28] <Lunar_Lander> yea
[19:28] <Lunar_Lander> corrupt sensor data is like negative pressure altitude
[19:28] <Lunar_Lander> yeah, 8!
[19:28] SpeedEvil (~user@tor/regular/SpeedEvil) joined #highaltitude.
[19:29] <nigelvh> Yeah, most of the time they're not all in use, but I especially like having a number of them for debugging.
[19:29] <Lunar_Lander> which color are there?
[19:29] <Lunar_Lander> yea
[19:29] <nigelvh> Those are all little surface mount green ones.
[19:29] <Lunar_Lander> ah
[19:30] <nigelvh> You can also see I made the pads the wrong size for the capacitors I bought, so I stand them up on their sides to solder them.
[19:31] <Lunar_Lander> where exactly?
[19:31] <nigelvh> All of the little tan surface mount capacitors.
[19:31] <nigelvh> There are a number of them around the processor.
[19:32] <Lunar_Lander> yes!
[19:32] <Lunar_Lander> what is the sparkfun breakout?
[19:32] phirsch (~phirsch@xdsl-89-0-163-3.netcologne.de) joined #highaltitude.
[19:33] <nigelvh> In this photo I hadn't attached it yet, but a small 16mbit flash chip goes on there. I put it on a breakout so it would be easier to take the chip out and move to a different board or swap them out.
[19:33] <Lunar_Lander> ah
[19:33] <Lunar_Lander> as memory?
[19:34] <nigelvh> Yeah, to store all the data to. Invariably you lose some over the radio link, or the link is slow, so you can store much more, faster to the flash chip.
[19:34] <Lunar_Lander> yeah
[19:34] <Lunar_Lander> I have a SD card planned for that at the moment
[19:35] <nigelvh> I fiddled with SD cards, but didn't have much luck with them, so I went with these little flash chips that work pretty well.
[19:35] <nigelvh> Not as big as an SD card, but more than enough space and simple to use.
[19:36] <Lunar_Lander> yea
[19:36] <Lunar_Lander> how do you read them afterwards?
[19:37] <nigelvh> I have a bit of software that at bootup waits a few seconds for a serial command to dump the data. If it gets the command, it dumps the data, a different command would clear the flash, and no command just goes on to normal operation and appends data to the flash.
[19:37] <Lunar_Lander> ah
[19:37] <Lunar_Lander> and what chip would you use for that?
[19:37] <nigelvh> The flash?
[19:37] <nigelvh> Or the commands?
[19:38] <daveake> I did something similar - I had a command interpreter that the program entered if it saw ESC within the first few seconds
[19:38] <nigelvh> Yeah, all the processing just happens on the uC
[19:38] <Lunar_Lander> the flash chip
[19:38] <daveake> Commands including listing SD contents, erasing it, etc
[19:38] <Lunar_Lander> which model
[19:38] <Lunar_Lander> ah
[19:38] <nigelvh> http://www.sparkfun.com/products/301
[19:39] <Lunar_Lander> thanks
[19:39] <nigelvh> If you end up using that one, let me know. There's an arduino library I use for it.
[19:39] <Lunar_Lander> ah
[19:39] <Lunar_Lander> I think I'll try the SD first
[19:39] <nigelvh> Sounds good.
[19:39] <Lunar_Lander> but first have to manage sensors, then the LED system and the MOSFET
[19:39] <Lunar_Lander> :)
[19:40] <Lunar_Lander> as for the HIH-4030 we decided we'll try to make a voltage follower first
[19:40] <Lunar_Lander> but I already looked at having a breakout made for the HIH-5030
[19:40] <nigelvh> What are you trying to do?
[19:40] <Lunar_Lander> running that one at 3.3V
[19:40] <Lunar_Lander> wait
[19:40] BoggleJon (~jon@cpc1-cmbg10-0-0-cust144.5-4.cable.virginmedia.com) joined #highaltitude.
[19:40] <nigelvh> I thought the 4030 would run at 3 and the output is relative to the VCC voltage
[19:40] <Lunar_Lander> https://www.sparkfun.com/products/9569
[19:40] <nigelvh> I use a 4030, but run it at 5.
[19:40] <Lunar_Lander> yea
[19:41] <Lunar_Lander> we did that too but only got a static output of 7%
[19:41] <Lunar_Lander> even when breathing into the sensor
[19:41] <Lunar_Lander> we checked our math but that was OK
[19:41] <Lunar_Lander> so I found something on the sparkfun site
[19:41] <nigelvh> Ah, the datasheet looks like it won't quite go to 3.3
[19:41] <Lunar_Lander> https://www.sparkfun.com/tutorials/185
[19:42] <Lunar_Lander> "Ratiometric means that when the datasheet says that the sensor will output 2V at 40% humidity with a 5V supply, the sensor will therefore output (2V/5V = 0.4 * 3.3V = 1.32V) 1.32V at 40% humidity with a 3.3V supply. After some testing, the HIH-4030 works very well at 3.3V! But one problem with the HIH is that the sensor is so low power that the sensor doesn't output enough current to feed the ADC on the ATmega328."
[19:42] <Lunar_Lander> "On future revisions of the main board I will use a capacitor or a current-follower so that the readings are a little bit more accurate."
[19:43] <nigelvh> Hmm. I've used the 4030 straight into an ADC on my 1280 and had no issues.
[19:43] <nigelvh> But I run it at 5V
[19:47] <Lunar_Lander> yeah
[19:47] <Lunar_Lander> 3.3V seems to be the problem
[19:47] <Lunar_Lander> but I have everything else at that voltage too
[19:47] <Lunar_Lander> and that 3.3V arduino
[19:48] <nigelvh> 3.3V is convenient if you want to run off one lithium cell, but I generally use 5 on all my stuff and work down if I have to for a sensor.
[19:48] <Lunar_Lander> ah
[19:48] <Lunar_Lander> it was mainly cause of the ublox GPS
[19:48] <nigelvh> Yeah, I use a 5V gps as well.
[19:49] <Lunar_Lander> ah
[19:51] <nigelvh> This one to be precise. https://www.argentdata.com/catalog/product_info.php?cPath=23&products_id=144&osCsid=l8of73bk4v9d2miol9gtqmhm63

[19:55] <nigelvh> I just happened upon one that worked better for me.
[19:56] <Lunar_Lander> yeah
[19:56] <Lunar_Lander> and what radio modules do you use?
[19:57] <nigelvh> I use ham radio since I'm in the US so they're not applicable to you.
[19:57] <nigelvh> But this last year I used a Radiometrix HX1
[19:57] <Lunar_Lander> yeah
[19:57] <nigelvh> In past years I've used a different module
[19:58] <Lunar_Lander> XD btw there was an incident in Hamburg where a 23 year old drunk woman was using her cell phone and then a guy who was disturbed by the loudness threw the phone out of the tram window
[19:58] <Lunar_Lander> just read that
[19:59] <Lunar_Lander> nigelvh, well I in germany could use it when I have my license
[19:59] <nigelvh> Reminds me of the whole "no phones on planes" business. "It's for safety!" Yeah, safety of the jerk who's going to talk on their phone the whole time.
[20:00] <Lunar_Lander> yea
[20:00] <nigelvh> Well then you have your answer. I used the HX1, it worked pretty well. I guess it's just the UK folks who can't since it's higher power.

[20:33] <nigelvh> Another joy of IT to add to yesterday's list. Tape Backups.
[20:35] <zamabe> I remember cassette tapes, but not magnetic data tapes. Yay me!
[20:35] <nigelvh> Yep. Every two weeks I go through 6 - 3TB tapes and 8 - 800GB tapes backup up our data.
[20:36] <nigelvh> Little more than one can fit on an audio cassette
[20:36] <Lunar_Lander> they still make tapes these days?
[20:37] <nigelvh> Yep. Not going away anytime soon.
[20:37] <nigelvh> For long term backups of business data, they're still useful.
[20:37] <SpeedEvil> Use the cloud man!
[20:38] <nigelvh> You want to upload something like 25TB to the cloud every two weeks?
[20:38] Action: SpeedEvil considers finding a confused venture capitalist, and obtaining funding for high altitude servers.
[20:39] <Upu> Don't even get me ranting about LTO tapes they are still way better than hard drive based storage for anything other than small random accesses
[20:40] <SpeedEvil> Clearly the backup solution of the future is microSD
[20:40] <Upu> evening
[20:40] <nigelvh> Exactly. For Large/Long term backups tapes are superior.
[20:40] <Upu> Well in sea water I'll grant you SD cards are better
[20:40] <nigelvh> Having a balloon write to tape would be brilliant.
[20:41] <SpeedEvil> I was amused that you can quite easily swallow enough microSD to sustain a datarate of a gigabyte/s through your intestines.
[20:41] <Upu> Nothing makes me happier than going into a potential customer and ask what is the back solution "oh its 5 RDX cartridges" or even better "this portable hard drive"
[20:41] <nigelvh> As the old saying goes, don't underestimate the bandwidth of a truck full of tapes
[20:41] <Upu> RDX = Wank marketing
[20:41] <Upu> yup

[20:42] <Lunar_Lander> hi Upu
[20:42] <Upu> evening LL
[20:42] <nigelvh> It takes me what, 5 minutes to move 25TB of data down the road to the storage facility. Pretty phenominal bandwidth there.
[20:43] <Lunar_Lander> XD
[20:43] <Upu> thats pretty quick nigelvh
[20:44] <nigelvh> I know, and it only costs a dollar a month! (gross estimate (in gas))
[20:45] <Upu> lol
[20:45] <Upu> gotcha :)
[20:47] <Lunar_Lander> xD
[20:47] <fsphil> they'll cap it eventually
[20:47] <nigelvh> Our VMs all live on a SAN so they get replicated to another san at the Colo, so that's a bit slower, 30mbit\
[20:47] <fsphil> force you to drive at 1mph
[20:47] <fsphil> once you get past 1Gb
[20:47] <daveake> Get a faster car; double your productivity
[20:47] <nigelvh> OR a car that can hold more tapes
[20:48] <Upu> or get some LTO6's
[20:48] <fsphil> slingshot
[20:48] <Upu> Dave tried one of those ones
[20:48] <Upu> once
[20:48] r2x0t (~r00t@b607.praha.cas.cz) left irc: Read error: No route to host
[20:48] <nigelvh> Yeah, one of our drives is an LTO5 and one is an LTO3
[20:48] <Upu> payload still up there daveake ?
[20:48] <daveake> yup
[20:49] <fsphil> longest duration float ever
[20:50] <daveake> and lowest
[20:50] <Upu> borrow a quad copter to get it down
[20:50] <daveake> I have some helis
[20:50] <daveake> But I know how that would end up ...
[20:51] Action: SpeedEvil imagines a drop-bear-copter.

[21:35] <Laurenceb_> theres a bit of blur from the compression but you can make out quite small towns
[21:35] <Laurenceb_> wonder what camera they used
[21:35] <Laurenceb_> im guessing one shot per second or so with very long exposures and very large bit depth
