[07:51] <daveake> re the rpi webcam ... it apparently locks up after a random period of taking a shot every 5 seconds. I've seen it take 30 mins or 10 hours
[07:51] gonzo_mob (~gonzo_mob@213.205.225.179) joined #highaltitude.
[07:52] <daveake> At that point the webcam LEDs are on (those come on when it's taking a photo) and the USB power consumption is up as it normally is when taking a photo
[07:52] <daveake> Have tried restarting the USB subsystem but doesn't fix it
[07:52] <daveake> I can reboot from another session and then it all works again, so it doesn't need a power cycle
[07:53] <daveake> morning costyn
[07:54] <costyn> been away for a bit, but glad to report my payload is almost ready for deployment. however it now turns out I have some power supply problems

[07:55] <costyn> batteries are supplying 6v, but getting only about 3.2v on the regulated 5v pin on my board :(
[07:55] <daveake> What board? pi?

[07:56] gonzo_mob (~gonzo_mob@213.205.225.179) left irc: Ping timeout: 246 seconds
[07:56] <costyn> so I was wondering how much current a standard arduino board + gps + ntx draws
[07:56] <daveake> Depends on the GPS
[07:56] <costyn> then I can make a separate powersupply circuit to power it through the serial bus
[07:56] <daveake> Somewhere around 60-100mA
[07:56] <costyn> ublox 6 on a GPS Bee
[07:57] <daveake> About 80mA then
[07:57] <costyn> ok that's quite small, good :)
[07:57] <daveake> The pi takes 0.5A or so
[07:57] <daveake> :p
[07:57] <costyn> anybody used that for HAB yet?
[07:58] <daveake> Not that I know of, though a few people on the web have mentioned it
[07:58] <daveake> craag here is doing one
[07:59] <daveake> It's not an ideal tracker but it'd be fun to fly one
[07:59] <costyn> interesting... and what extra cool stuff is he planning to do with it?
[07:59] <fsphil> I'll be doing one too but not for a while
[07:59] <daveake> GPS + sensors I believe
[07:59] <daveake> I'm doing GPS + SSDV
[08:00] <fsphil> for mine I'll be doing nbtv (narrow band tv)
[08:00] <costyn> ah cool, the extra processing power will come in handy then eh?
[08:00] <daveake> oo look at you
[08:00] <costyn> hehe
[08:00] <fsphil> lol
[08:00] <daveake> Yes :-)
[08:00] <fsphil> a tv standard from the 40s or something

[08:01] <daveake> For mine I have a tracker in C that does the GPS parsing and rtty transmission (telemetry and stills)
[08:01] <daveake> and a separate shell script that takes the photos and saves to the SD card
[08:02] <daveake> The C program then chooses the best* recent shot to send
[08:02] <costyn> ok, well, off to look for a voltage reg
[08:02] <daveake> *largest jpg file size ( c ) fsphil
[08:02] <daveake> reg for ?
[08:02] <fsphil> have you tested it on real images daveake?
[08:02] <costyn> hehe... Tim had an algorithm on his beagleboard which also picked out the best pic too
[08:03] <daveake> fsphil ish
[08:03] <costyn> daveake: for my power supply for my board :)
[08:03] <daveake> from what to what at what ?
[08:03] <costyn> from 4-6 volts to 5v
[08:03] <daveake> step up/down then
[08:03] <costyn> something like the LM7805 although it's probably
[08:03] <costyn> too lumpy
[08:03] <costyn> and only does step-down
[08:03] <number10> how do I get fldigi working on my 441 line tv for decoding
[08:04] <daveake> number10 What size hammers do you have?
[08:04] <fsphil> 441 lines? fancy
[08:04] <fsphil> this will be 28 line or something silly
[08:04] <number10> thats reqquired for decoding fsphil next project no?
[08:04] <fsphil> there will be software :)
[08:05] <fsphil> probably not dl-fldigi
[08:05] <number10> oh cool, as I think the HT is nackered in the tv
[08:05] <daveake> :)
[08:05] <fsphil> I'd love to see someone receive it with a mechanical tv :)
[08:06] <fsphil> though the format probably won't be the same as the old ones
[08:06] <number10> just going to find my sledge hammer
[08:06] <fsphil> I don't want the taller image
[08:06] <fsphil> I'll stick with 4:3

[10:32] <navrac> prediction - hmm. Depends. If I go with 2xAA it floats about 100km of holland and ends up in denmark
[10:33] <navrac> if I can find some AAA lithiums it floats about 3k higher, does a loop in the north sea and heads to denmark
[10:34] <navrac> oops other way round
[10:34] <Upu> that might be out of range for me
[10:34] <navrac> but the chances ofgetting aa lithiums round here is pretty remote.
[10:35] <Upu> tesco ?
[10:42] <navrac> nearest tesco that stocks them is about 25 miles away
[10:42] <navrac> maybe 15 miles
[10:43] <navrac> just been phoningthe local shops - no luck yet
[10:43] <Upu> we have 3 tescos within 3 miles here

[10:43] <navrac> not much round here apart from small village shops
[10:44] <fsphil> odd, tesco here has them too
[10:45] <fsphil> sometimes even fairly priced
[10:45] <navrac> there is a small tesco about 10 miles away - but it doesnt do lithiums
[10:45] <number10> tescos at saxmundham
[10:46] <navrac> thats the one - only does alkaline
[10:46] <number10> mm thats unfortunate
[10:47] <number10> tesco had a good price on the AAs instore - 4.50 4pk
[10:47] <navrac> I dont know sax well, dont think there is anywhere else likely to do them

[11:02] <navrac> right - off for a lithium hunt - cant go far- got to be back for the gp qualifying
[11:02] <fsphil> noooo not more sports
[11:02] <fsphil> I officially declare that for all of 2013 everyone should just sit around and be lazy
[11:04] <number10> fsphil - I just got ft817 - should the power bars flash to indicate 5W when plugged into 13.8v?
[11:04] <navrac> that is what formula 1 is - sitting in a car
[11:04] <fsphil> when on battery yes
[11:05] <fsphil> it's not clearly described in the manual -- I think the power indicator flashes when on 5W and the voltage is below a certain level
[11:05] <SpeedEvil> fsphil: Works for me. How do you feel about starting 6 months early?
[11:06] <number10> strange - I can cycle though the settings - but when on 3 bars and external PSU connected it doesnt flash - I probbably have something wrong
[11:07] <fsphil> hmm.. might impact the olympics SpeedEvil
[11:07] <number10> I still have the internal NMHI connected
[11:07] <fsphil> three bars is 2.5w
[11:07] <fsphil> isn't it? *checks*
[11:08] <number10> I think so
[11:08] <number10> and it says flashing for 5w
[11:08] <fsphil> three bars solid is 2.5W
[11:08] <fsphil> three bars flashing is 5W with low voltage
[11:08] <fsphil> and no bars is 5W when not running on battery
[11:09] <number10> ah so no bars 5w.. thats silly
[11:09] <fsphil> lol yep
[11:09] <fsphil> with some psus, it has no bars until I start to transmit, the voltage drops and it starts blinking
[11:09] <number10> cheers fsphil ... doesnt take much to confuse m these days
[11:10] <fsphil> it's not terribly clear

[11:10] <SpeedEvil> As in actual proper branded ones.
[11:10] <Upu> dealextreme
[11:11] <Upu> oh :)
[11:11] <SpeedEvil> Ideally cheap - but meh.
[11:11] <Upu> Get the trustfire ones from Dealextreme
[11:11] <SpeedEvil> I really want ones that are likely to work for a reasonable number of cycles.
[11:11] <Upu> they are easy to spot as amusingly they have flames on the side

[15:06] <SpeedEvil> Interesting.
[15:08] <SpeedEvil> So the bottom one on tht list'd hold about 1.8m^3, and weigh 400g or so
[15:09] <SpeedEvil> So maybe closing on 2kg of free lift.
[15:09] <SpeedEvil> Or for a whole pack - 500kg
[15:10] <SpeedEvil> How much is 1000m^3 of hydrogen?
[15:10] <daveake> Well 7.2 is £44+VAT
[15:10] nosebleedkt (~nosebleed@ppp046177125203.access.hol.gr) joined #highaltitude.
[15:14] <SpeedEvil> Interesting.
[15:15] <SpeedEvil> Natural gas is about 66p for the same lift as 1m^3 as H2

[15:15] nosebleedkt (~nosebleed@ppp046177125203.access.hol.gr) left irc: Ping timeout: 255 seconds

[15:22] <mclane> Hello, question to the professionals: what is the recommended coding for the rtty strings: 7n1? 7n2?
[15:22] <Laurenceb_> i get 100gram mass or so
[15:22] <Laurenceb_> its 12gram/m^2
[15:24] <fsphil> mclane: 7n2 is fine
[15:25] <mclane> thanks fsphil
[15:25] <fsphil> 7n1 should be better, but fldigi's modem works better with 2 stop bits
[15:26] nosebleedkt (~nosebleed@ppp046177125203.access.hol.gr) left irc: Ping timeout: 240 seconds
[15:26] <SpeedEvil> Laurenceb: For the 1.4*1.6*0.8m one - the area is 1.4*1.6*2 + 0.8*(1.6+1.4)*2
[15:26] <SpeedEvil> Or 9.2m^2
[15:26] <SpeedEvil> *.048 = ~400g
[15:27] <SpeedEvil> Oh
[15:27] <SpeedEvil> Fail.
[15:28] <SpeedEvil> I was thinking 48g was 48g/m^2
[15:28] <SpeedEvil> A micron*1m^2 weighs a gram of course (water) - so it's of the order of 12g/m^2, prolly 10g/m^2
[15:29] <SpeedEvil> so more like 90g indeed
[15:31] nosebleedkt (~nosebleed@ppp046177125203.access.hol.gr) joined #highaltitude.
[15:32] <Laurenceb_> so cruise at 12Km with 100gram payload
[15:34] <SpeedEvil> And 30p worth of natural gas.
[15:34] <SpeedEvil> Total launch cost of well under a pound.
[15:35] <number10> ha fsphil now you tell us ; I use 7n1
[15:35] <fsphil> it mostly only matters at 300 baud
[15:35] <SpeedEvil> What sort of payloads could you do with balloons costing a pound...
[15:35] <number10> :) I dont feel so bad now
[15:35] <fsphil> but it probably has some slight effect at 50 baud too

[15:36] <fsphil> (that's good)
[15:36] <number10> :)
[15:36] <SpeedEvil> If you had multiple closely seperated in frequency beacons, on balloons - and enough recievers, you could do the SDR thing, and generate relative positions for them all.
[15:37] <SpeedEvil> You need enough recievers that you can overdetermine the position, and solve for frequency offset of each reciever.
[15:37] <SpeedEvil> I think.

[17:44] <costyn_> daveake: Just read the specs again... says it needs 7-12 volts, so the 6 I'm giving it just aren't enough for the onboard voltage reg
[17:45] <costyn_> SpeedEvil: I know that feel, bro :)
[17:45] <SpeedEvil> Alcohol wasn't involved, either.
[17:48] <Lunar_Lander> yea
[17:49] <daveake> costyn Yeah, many linear regulators need at least 2V difference between Vin and Vout
[17:49] <SpeedEvil> Depends - LDOs may be lots less
[17:49] <Lunar_Lander> costyn_, which one do you use?
[17:49] <Lunar_Lander> I mean I run the sparkfun one at 4.5V and it gives out 3.3V OK
[17:49] <daveake> Yes
[17:50] <daveake> Some LDOs though drop 1.5V. Not Low in my book!
[17:50] <daveake> The ones I use are around 0.3V for full current
[17:50] <costyn_> Lunar_Lander: the seeedstudio stalker v328 has a LM1117 on it
[17:50] <Lunar_Lander> ah
[17:50] <Lunar_Lander> that is the one afaik
[17:50] <Lunar_Lander> or what voltage does it have?
[17:51] <costyn_> daveake: so it seems... what is the voltage levels of energizers? anybody have a link to a chart for a constant current load?
[17:51] <Lunar_Lander> ah sparkfun has LD1117V33
[17:51] <daveake> Energizers start at 1.8V but very quickly drop to 1.6V
[17:51] <costyn_> Lunar_Lander: well my batteries were feeding it 6v (measured while it was running) and the 5v pin was giving 3.5v or so. the ntx didn't sound very healthy
[17:52] <Lunar_Lander> yes
[17:52] <daveake> When they're cold the voltage is lower than normal
[17:52] <Lunar_Lander> ah
[17:52] <daveake> My rule of thumb is to treat them as dead at 1V. in other words, I want my payload to still be running down to that point.
[17:52] <costyn_> well I have 5 slots for AA batteries, so I should be ok until they drop to 1.4
[17:53] <daveake> For a 3.3V board, an LDO of 0.5V or less (the Arduino Mini Pro drops about 0.25V IIRC) is needed
[17:53] <costyn_> daveake: it would seem I would need more than 5 batteries, which seems excessive.
[17:53] <daveake> Then you can use 4 AAs
[17:53] <costyn_> well i have it set up for 5, which is ok I guess

[17:54] <daveake> Just
[17:54] <daveake> For 5V I use a 0.5V dropout reg, and 6 AAs
[17:54] <costyn_> 5*1.4 = 7 volts... anything below is getting into murky territory
[17:55] <costyn_> daveake: ok... have a link to the 0.5v reg?
[17:55] <daveake> Use a better regulator anyway
[17:55] <daveake> Just a mo
[17:55] <costyn_> use a reg different than the onboard one you mean right?
[17:56] <daveake> For the pi I'm using an LM2940CT-5. 1A max, 0.28V drop @ 0.5A
[17:56] <daveake> Replace the onboard one
[17:56] <costyn_> do you solder a diffrent one onto the board? or just connect it to the vcc of th board?
[17:56] <daveake> Either
[17:57] <daveake> In this case it's off board as I want to put a heatsink on it
[17:57] <daveake> Remember the pi runs at 400mA
[17:57] <costyn_> that's a lot yes :)
[17:57] <daveake> And convection at 1% atmosphere is not good!
[17:57] <SpeedEvil> you want to set it to 4.5V or so
[17:58] <SpeedEvil> As it will run at that, and use ~10% less
[17:58] <SpeedEvil> err
[17:58] <SpeedEvil> yeah
[17:58] <SpeedEvil> Conduction is actually unaffected
[17:58] <costyn_> daveake: but you would use the LM2940CT-5 for any 5v device that you'd design? even an arduino type board?
[17:58] <SpeedEvil> Until you hit about a pascal, conduction to air isn't affected
[17:58] <costyn_> SpeedEvil: what about convection?
[17:59] <daveake> Sure, but it's a TO220 package so it might not fit on your board
[17:59] <SpeedEvil> It's annoying if you're tryng to do vacuum insulation
[17:59] <SpeedEvil> costyn_: majorly
[17:59] <Lunar_Lander> but TO220 looks cool
[17:59] <Lunar_Lander> xD
[17:59] <Lunar_Lander> (sorry for the stupid remark)
[17:59] <costyn_> daveake: I'll just dead bug it
[17:59] <daveake> SpeedEvil the 5V is for the USB - webcam. I have a separate regulator for the 3.3V line.
[18:00] <SpeedEvil> daveake: ah - you'd removing the 3.3V linear?
[18:00] <daveake> The pi 3.3V reg has 1.2V dropout; the one I'm using has about 1/4 of that
[18:00] <daveake> Check
[18:00] <SpeedEvil> (actually - simply setting your reg to 3.4 should work)
[18:00] <costyn_> electronics is a great hobby... parts are so cheap :)
[18:02] <costyn_> daveake: would you recommend I use a heatsink too? cause I only use less than 100 mA?
[18:02] <daveake> Also the mcp1825s50 is very good
[18:03] <daveake> < 100mA and 5 AAs? No, you'll be fine
[18:03] <costyn_> daveake: cool thx
[18:04] <daveake> But to check look at the data sheet. It will tell you how many degrees of temperature elevation per watt without a heatsink
[18:04] <costyn_> ok
[18:06] <costyn_> daveake: thanks for your help. saves me a lot of time and headache worrying if it'll be allright. now I know it'll be ok :)
[18:07] <daveake> Right, it's 60 degrees per watt
[18:07] <daveake> So 5 x AA @ 1.8V (not for long) = 9V, so that's 4V across the device, times 0.1A = 0.4W
[18:07] <daveake> So temp rise is 0.4 * 60 which is 24 degrees
[18:08] <daveake> Which is not very much
[18:08] <costyn_> no should be ok :) cool supertanks!
[18:08] <daveake> For the pi I've added heatsinks :)

[20:02] <daveake> Not at present. Believe there might be one in development.
[20:03] <eroomde> a mobile-friendly web client would be cool
[20:03] <eroomde> as most of us whoe tried know by now, the tracker can make short work of most mobile browsers
[20:03] <daveake> it would
[20:04] <eroomde> even my new shiny spiffy ipad 3 crashes completely as soon as it tried to load the path

[21:44] <Upu> there is a difference between ultimate lithiums and normal lithims
[21:44] <SpeedEvil> really?
[21:44] <SpeedEvil> I mean the 1.5V sort

[21:46] <Upu> those are the ultimate ones
[21:46] <daveake> Lithium iron disulfide - should be the same
[21:46] <Upu> trying to find the data sheet there is a difference
[21:46] <daveake> ok
[21:46] <daveake> I wouldn't take the risk without seeing the data sheet

[21:50] <SpeedEvil> Ok - I don't care about self-discharge - because it's going to be used in ~3 years anwya
[21:51] <Upu> I can't make a comparison because the data sheets aren't doing like for like
[21:51] <Upu> My advice would be buy both and test
[21:51] <SpeedEvil> Ok - advanced says 550 hours at 10mW - or 5.5Wh.
[21:52] <SpeedEvil> And ultimate 450 hours, or 4.5Wh
[21:54] <Upu> you will be using more than 10mW though

[23:26] <Laurenceb_> i see no difference in datasheet
[23:26] <Laurenceb_> both just over 3Ah /AA cell
[23:26] <SpeedEvil> hmm
[23:26] <SpeedEvil> I was reading the 10mW power line
[23:26] <SpeedEvil> One is considerably higher than the other
[23:27] <SpeedEvil> I guess in my app I probably don't care about power, but current, but I diddn't see a nice current vs mAh graph
[23:27] <Laurenceb_> oh the voltage
[23:27] <Laurenceb_> i see
[23:27] <SpeedEvil> Is one voltage higher?
[23:27] Action: Laurenceb_ looks again
[23:28] <SpeedEvil> I should probably measure Ipk for my RF sender thingy
[23:29] <Laurenceb_> oh yeah advanced is slightly better
[23:29] <Laurenceb_> the toy example
[23:31] <Laurenceb_> maintains voltage slightly better
[23:37] <Laurenceb_> no wait they changed the scale
[23:37] <Laurenceb_> i think its the same graph
[23:38] <SpeedEvil> If you read the mWh out from the graph, you clearly get a different result
[23:38] <SpeedEvil> Unless it's mislabeled.
[23:38] <SpeedEvil> Or I misread
[23:39] <Laurenceb_> which graph?
[23:40] <Laurenceb_> oh yeah
[23:40] <Laurenceb_> 4.5/5.5
[23:41] <Laurenceb_> but advanced has higher ESR
[23:41] <Laurenceb_> and "only" 10 years shelf life
[23:41] <Laurenceb_> looks like the toy example ends up very similar

[23:42] <Laurenceb_> i think someone at energizer is copying and pasting the data
[23:43] <Laurenceb_> zoom in and look at the kinks
[23:43] <SpeedEvil> hmm
[23:43] <Laurenceb_> definately a different battery tho
