[08:46] <AndyEsser> morning
[08:51] <AndyEsser> stupid question, if I have something that requires 1A running for an hour... that's 1Ah, right?
[08:52] <eroomde> yes
[08:53] <AndyEsser> cool - so if my device draws 100mA, a 1Ah battery will last for ~10 hours?
[08:53] <eroomde> no
[08:54] <eroomde> well maybe
[08:54] <eroomde> the other variable you haven;t mentioned is voltage
[08:54] <eroomde> ssuming the battery voltage is the same as the required voltage, yes
[08:54] <AndyEsser> Yes, apologies - assumption on my part.
[08:54] <eroomde> but for example a 1Ah 10V battery supplying a 1A 5V device through a perfectly efficient dc-dc converter will last 2 hours
[08:54] <AndyEsser> Ok, just wanted to check my basic understanding of Ah was correct
[08:55] <AndyEsser> That makes sense
[08:55] <eroomde> often however the battery ratings in Ah are actually dependant on the current
[08:55] <eroomde> so it might be 1Ah at 0.1A but 0.8Ah at 1A
[08:55] <AndyEsser> ah ok
[08:55] <eroomde> because of internal resistence
[08:55] <eroomde> P= I^2 * R
[08:56] <AndyEsser> so I can at least get a good enough idea of how long my battery will last
[08:56] <AndyEsser> thanks
[08:56] <eroomde> so the more current you draw, the quadratically more power is wasted as heat through internal resistance
[08:57] <AndyEsser> ok cheers

[09:11] <Vaizki> the L91 data sheet for example has a curve for current draw / capacity
[09:11] <AndyEsser> Vaizki: yep, as soon as eroomde mentioned that feature, I assumed the datasheets would have something like that
[09:14] <Vaizki> well I remembered wrong.. they have Voltage/Capacity (discharge) and Capacity / Temperature .. both graphs with different discharge currents
[09:15] <AndyEsser> I'll do some proper testing when I've build stuff anyway, and if needs be go for higher capacity batteries, but at least I should be able to get an estimate
[09:15] <Vaizki> even with SD card you should fit under 100mA
[09:15] <Vaizki> average that is
[09:15] <AndyEsser> 100mA was just a number, not what I think it'll draw
[09:15] <AndyEsser> I still need to calculate it
[09:16] <AndyEsser> tonight is my only free night for the next week and a half or so
[09:16] <Vaizki> oh no I wasn't referring to your comment but my experience

[11:56] <Ben-AstroSoc> when parsing huge decimals from NMEA (longitude/latitude is in format DDDMM.MMMMM) would it be better just to parse it as a String or multiply out the decimal and save it as uint64_t?
[11:57] <mattbrejza> na just string copy
[11:57] <mattbrejza> avoids cockups
[11:58] <mattbrejza> also less code space etc
[11:58] <Ben-AstroSoc> worth doing the same for altitude too? consnidering that fits in a uint32_t
[11:58] <Ben-AstroSoc> yeah might just refactor what i've written
[11:58] <Ben-AstroSoc> less local variables
[11:58] <eroomde> it depends on whether or not you actually need to know the numbers
[11:59] <eroomde> if you're just repeating it back over a radio, probably best to not
[11:59] <Ben-AstroSoc> i mean i'm not doing any on-processor working other than sending it all bak with our sensor data appended
[11:59] <SpeedEvil> If you're doing geofencing, then you'll need to
[11:59] Hix (~hix@97e0a009.skybroadband.com) joined #highaltitude.
[11:59] <eroomde> if you're acting on the information (a cutdown or whatever) then obviously yes you need to parse it
[11:59] <Ben-AstroSoc> *googles geofencing*
[11:59] <Ben-AstroSoc> nah for this launch we're not doing cutdowns or anything
[11:59] <Ben-AstroSoc> just transmitting
[11:59] <SpeedEvil> do you wantt o do something when it crosses a line on a map
[12:00] <Ben-AstroSoc> ah
[12:00] <Ben-AstroSoc> not for this iteration
[12:00] <Ben-AstroSoc> a'ight cheers
[12:00] <mattbrejza> i probably wouldnt bother converting a string to int then back to string again
[12:00] <mattbrejza> doesnt seem work it
[12:00] <mattbrejza> worth it
[12:01] <Ben-AstroSoc> i mean if i need it later on i'll refactor my parser to pull out the int
[12:01] <Ben-AstroSoc> don't need it for the moment so will keep it simple
[12:01] <kokey> I thought for a moment there that geofencing is a new type of hobby kind of like geocaching
[12:02] <kokey> well I suppose it can be a hobby for some
[12:05] <gonzo_> a mix of orienteering and dry stone walling ?
[12:05] <eroomde> i admire your lunge-itude

[12:12] <Ben-AstroSoc> not looked at the UKHAS software yet so is there a format for data strings as theyre uploaded online or is it something we define later?
[12:13] <AndyEsser> Ben-AstroSoc: you define your telemetry string later
[12:13] <AndyEsser> basically it starts
[12:14] <AndyEsser> $$callsign,data,data,data,data,data*checksum
[12:14] <AndyEsser> and then you just tell it which data section is what
[12:14] <Ben-AstroSoc> right, as long as its arbitrary
[12:14] <AndyEsser> longitude, latitude, number of satellites, etc
[12:14] <Ben-AstroSoc> i didn't wanna write a bunch of stuff then find there was a format i should be transmitting on
[12:16] <Ben-AstroSoc> the checksum is that CRC16 algorithm right?
[12:17] <AndyEsser> err, can't remember the exact algo
[12:17] <AndyEsser> it's on the UKHAS wiki somewhere
[12:17] <Ben-AstroSoc> yeah
[12:17] <Ben-AstroSoc> not up to there yet so

[12:32] <Vaizki> buying test equipment
[12:32] <mfa298> the Arduino softserial library has been found to be pretty poor in the past, using a proper uart for gps is preferable if you can
[12:32] <Vaizki> testing test equipment with test equipment
[12:33] <Ben-AstroSoc> we're using UART for GPS and softserial for our telemetry Tx
[12:33] <AndyEsser> Vaizki: testception
[12:33] <Ben-AstroSoc> + in raw C not arduino
[12:33] <AndyEsser> Ben-AstroSoc: which uC are you using?
[12:33] <AndyEsser> 328?
[12:33] <Ben-AstroSoc> ye
[12:33] <Vaizki> I think every other viable uC has 2-5 uarts except 328...
[12:33] <AndyEsser> cool - give me a shout if you have any issues :) Happy to help if I can
[12:33] <AndyEsser> the 644 is probably a better choice
[12:34] <AndyEsser> 2 uarts, more memory etc
[12:34] <AndyEsser> but otherwise basically identical I believe

[12:34] <Vaizki> or 328pb ;)
[12:34] <Ben-AstroSoc> can't remember the exact reason bu ti think the uni had 328s on hand so we went with it
[12:34] <AndyEsser> seems as good as a reason as any
[12:34] <AndyEsser> bit-banging the radio TX is easy peasy
[12:34] <Ben-AstroSoc> i don tmind having to write the extra code, ends up teaching me something
[12:34] <AndyEsser> so using i2c or uart for the GPS is then a no-brainer
[12:34] <Ben-AstroSoc> we didnt cover much C but i was good at it so
[12:35] <Ben-AstroSoc> yep
[12:35] <Ben-AstroSoc> UART gps and gotta work out I2C for our sensors
[12:35] <AndyEsser> I personally use i2c as I keep the UART for pure debugging atm
[12:35] <mattbrejza> two serial ports on an avr is nice as you can have one for debug and one for gps
[12:35] <mattbrejza> i2c is a bit eww
[12:35] <AndyEsser> mattbrejza: works well enough for the ublox GPS I've found so far
[12:35] <mattbrejza> doesnt mean i like it :P
[12:35] <AndyEsser> true :P

[13:11] <AndyEsser> it appears lunar_lander is making progress
[13:11] <AndyEsser> (assuming it's him)
[13:11] <craag> Yep

[13:15] <LunarMobile> Hello
[13:16] <AndyEsser> LunarMobile: it appears you're making progress
[13:16] <LunarMobile> Yes
[13:16] <AndyEsser> cool
[13:16] <AndyEsser> grats
[13:17] <LunarMobile> Thanks
[13:17] <Vaizki> the eagle has landed?
[13:17] <AndyEsser> LunarMobile: actually launching? or just a test?
[13:17] <LunarMobile> Testing
[13:18] <AndyEsser> when are you launching?
[13:18] <LunarMobile> Launch postponed to Friday
[13:18] <craag> :(
[13:18] <LunarMobile> 9 gmt
[13:18] <AndyEsser> cool
[13:18] <LunarMobile> Yea wind too strong
[13:18] <AndyEsser> (not cool about the postponement - but cool it's not too far away)
[13:18] <craag> Fair enough!
[13:18] <LunarMobile> Yea :)

[13:26] <fsphil> does seem to be a tad breezy in places today
[13:27] <LunarMobile> It is
[13:28] <Geoff-G8DHE-Lap> Just mildly! My 70cms aerial has twisted to right angles on the elevation pole so taking the full strength of the wind :-(
[13:32] <gonzo_> my whole mast is only held in place by a couple of bits of rope at the momnet
[13:32] <gonzo_> could be interesting!
[13:34] <Geoff-G8DHE-Lap> Mine are all steel guy lines these days, no problem with them but its the extra forces on the rotators which is more worrying.
[13:34] Hix (~hix@97e0a009.skybroadband.com) left irc: Remote host closed the connection
[13:34] <mattbrejza> wind has been pretty tame so far, not even any wheelie bins across the path this morning
[13:34] <LunarMobile> Happy to see the system worked
[13:35] <AndyEsser> tis rather windy round here as well
[13:36] <Geoff-G8DHE-Lap> My anemometer peaked at 46.1mph 74Km/hr
[13:36] <Geoff-G8DHE-Lap> @ 11.55 this morning
[13:36] <AndyEsser> wish I had space and permission for a mast and things
[13:37] <gonzo_> when I say a bits of rope, I don't mean guys, I mean the whole mast
[13:38] <gonzo_> (I will have to tie another couple of bits on if it's still there when I get home)

[13:44] <fsphil> how often do you get blamed for TV interference? :)
[13:45] <Geoff-G8DHE-Lap> Very little these days, had a tussle a few years back with a local aerial erector
[13:46] <AndyEsser> *sniggers*
[13:46] <Geoff-G8DHE-Lap> who decided to fit pre-amps on all the aerials
[13:46] <fsphil> I know the type
[13:46] <Geoff-G8DHE-Lap> trouble was there was a paging transmitter just 300m away running 200W from the fire station
[13:47] <Geoff-G8DHE-Lap> eventually he decided he would replace (bypass) them after I dropped letters into all of them explaining some of the problems and the signal strengths in the area!
[13:57] Hix (~hix@97e0a009.skybroadband.com) joined #highaltitude.
[14:00] <gonzo_> since the tv all went digital, you don't see the good old herringbone patterns and woofing of ssb in the tv sound
[14:00] <gonzo_> it just dies, so it's not obvious who's causing it
[14:01] <R34lB0rg> you also no longer get to see comic microwave background radiation
[14:01] <Geoff-G8DHE-Lap> Indeed and the old RFI teams no longer exist to track anything down
[14:02] <Geoff-G8DHE-Lap> You mean we didn't need all those aerials and satellites to measure the CMB? Just had to look at the tele's :-)
[14:03] <R34lB0rg> part of the noise when you tuned between channels was caused by CMB

[14:04] <Geoff-G8DHE-Lap> Indeed, but hav ?
[14:04] <Geoff-G8DHE-Lap> e you figured out how much ?
[14:06] <R34lB0rg> about 1% - http://www.universetoday.com/25560/the-switch-to-digital-switches-off-big-bang-tv-signal/
[14:06] <Geoff-G8DHE-Lap> or less ... much less!!

[14:10] <eroomde> i think that the total amount of energy (in the freqs of interest) collected by all radio astronomy ever is some number of millijoules
[14:11] <R34lB0rg> tv receivers whose owner dozed off probably account for more ;)

[14:14] <gonzo_> tv rx were always exceptionally deaf
[14:15] <gonzo_> the noise temp was so high, that you would not be able to make out background radiation
[14:15] <gonzo_> also the antennas would be seeing an abverage of 150K is of thermal noise
[14:16] <SpacenearUS> New vehicle on the map: 03CHANGEME - 12http://tracker.habhub.org/#!qm=All&q=CHANGEME
[14:16] <daveake> ^ just me testing a customer's tracker that "doesn't work"
[14:16] <gonzo_> the tracker of the customer?
[14:16] <gonzo_> or
[14:17] <daveake> issue appears to be with the former
[14:18] <AndyEsser> PEBCAK
[14:19] <Geoff-G8DHE-Lap> No be fair Dave the have a very sensitive Rx that is being swamped by the CMB noise.
[14:19] <daveake> yeah somewhere between those items

[14:20] T-MaN (~thomas@217.21.233.78) joined #highaltitude.
[14:20] <daveake> I suspect that, given that the SD card booted the Pi into X, he's not entirely followed instructions
[14:21] <daveake> and consequently has been running the tracker programs from a terminal window
[14:21] <daveake> without realising it all autoboots
[14:22] <AndyEsser> oof
[14:26] <daveake> and yes the instructions tell you to switch X off if you've used the latest "full" Jessie, right after it tells you to use the "Lite" one instead
[14:26] <daveake> and explains about autoboot, but hey people don't always read.
[14:26] <AndyEsser> not easier to just provide an SD card download with it all done?
[14:27] <eroomde> could just fedex them a f*cking massive cardboard box with a fully inflated balloon and working payload inside
[14:27] <eroomde> they just cut it open
[14:27] <eroomde> boom they've done a hab, clever them
[14:27] <R34lB0rg> people only read when something does not work out of the box, and even then not all of them
[14:28] <AndyEsser> eroomde: part of me would love to see that :)
[14:29] <eroomde> 'it didn't say i shouldn't use a big knife to open the box, it's not my fauly the balloon burst'
[14:29] <R34lB0rg> maybe with a small disposable bottle with the correct amount of helium
[14:29] <eroomde> what is the correct amount
[14:30] <eroomde> don't answer infact
[14:30] <Vaizki> :D
[14:30] <R34lB0rg> depends on weight of balloon, tracker and the desired ascend rate

[14:30] <eroomde> my reflex to enter a socratic dialogue with someone should not be seen by them as anything other than a slower way of telling them that what they said doesn't make any sense
[14:31] <eroomde> at least with some people
[14:32] <eroomde> right this software is now passing its tests again so i must get back to writing. ttfn
[14:32] <AndyEsser> o/
[14:32] <R34lB0rg> it makes sense with a ready-to-fly kit where you know these values
[14:34] <daveake> Yeah, the idea of the PITS board is to make it quicker to get tracking working, not to provide an "unbox and go" solution.
[14:35] <R34lB0rg> people expect "unbox and go" solutions these days
[14:35] <daveake> R34lB0rg No it still makes no sense. One of the key things for launch is to control the flight path, by (e.g.) using more or less gas
[14:36] <gonzo_> if it were too easy, idiots would manage it and f'k it up for everyone. eg. The current quidcopter/drone situation

[14:36] <R34lB0rg> daveake, that's beyond people who would buy a ready-to-fly kit
[14:36] <daveake> Then they should be kept away from such a thing
[14:37] <daveake> There's a lot to flying a balloon, and some of it should not be short-circuited
[14:37] <fl_0> re
[14:37] <AndyEsser> aww :(
[14:37] <fl_0> hi daveake
[14:37] <daveake> hi
[14:37] <R34lB0rg> gonzo_, in my country it's already fucked up :-( can only fly drones up to 150m
[14:37] <fl_0> we got current and voltage measurements working
[14:37] <DL1SGP_> hey there fl_0 :)
[14:37] <fl_0> :)
[14:37] <fl_0> DL1SGP_: ahoi
[14:38] <R34lB0rg> daveake, I agree with you to the point that people should generally not be allowed to use technology they do not understand
[14:38] <AndyEsser> R34lB0rg: that now procludes most of the population from using phones/tablets
[14:38] <R34lB0rg> but commerzialization will sooner or later breed a ready-to-fly hab kit
[14:39] <R34lB0rg> AndyEsser, estimate the situational awareness of people using a smartphone/tablet on the street
[14:39] kristianpaul (~kristianp@unaffiliated/kristianpaul) left irc: Ping timeout: 240 seconds
[14:39] <AndyEsser> R34lB0rg: that has nothing to do with your statement
[14:40] <gonzo_> the great unwashed don't know about/care about/ignore the laws about flying drones, so they would be less likely to worry about regs concerning balloons
[14:40] <daveake> R34lB0rg You're agreeing with something I didn't say
[14:40] <AndyEsser> "people should generally not be allowed to use technology they do not understand
[14:40] <AndyEsser> "
[14:40] <AndyEsser> taken straight from your statement
[14:41] <AndyEsser> and I neither agreed nor disagreed
[14:41] <SM0ULC-Reb> R34lB0rg: wher do you live?
[14:41] <AndyEsser> good lord
[14:41] <AndyEsser> ....
[14:41] <R34lB0rg> AndyEsser, if people are overchallenged by smartphones to the point that they crush into other people (and possibly traffic) - they should not use it
[14:42] <AndyEsser> how on earth did I manage to read both gonzo_ and daveake's names as re
[14:42] <R34lB0rg> SM0ULC-Reb, austria
[14:42] <daveake> You don't need to understand how a car works to be able to drive; you do though need to understand the rules of the road and how to control said vehicle safely
[14:42] <AndyEsser> R34lB0rg: not being able to be aware of your surroundings when using a smartphone does not mean they understand, or conversely do not understand the technology
[14:42] <AndyEsser> again - their situational awareness has nothing to do with your prior statement
[14:43] <daveake> So the HAB course I ran last year was all about flying safely with a good chance of recovery, and not so much about how trackers work
[14:43] <AndyEsser> daveake: which I suspect was great a for a large proportion of people who want to "make it fly"
[14:43] <R34lB0rg> AndyEsser, someone who is able to build a smartphone presumably has the metal capacity not to be distracted by it
[14:43] <AndyEsser> not necessarily
[14:43] <AndyEsser> the two skills aren't related
[14:43] habby (~habby@host-92-16-186-164.as13285.net) joined #highaltitude.
[14:45] <daveake> AndyEsser They were mostly teachers. We had 1 day classroom and 1 day flying, so it was quite intensive. No time for "look at this C code", so the tracking side was more about radio, line of sight, setting up receivers etc.
[14:45] <AndyEsser> Yea, which I think makes sense for a lot of people
[14:45] <AndyEsser> "I want to accomplish something in 2 days, what do I need to know to do that?"
[14:46] <daveake> Yes it's not what's encouraged here, of course, which is "make the thing yourself from scratch". As it should be.
[14:46] <gonzo_> whilst a hobby is with a small and resaonably sensible minority, the authorities are not to worried about it. As soon as it is made to easy, so the wider public get involved, then the clueless or idiots get onboard. That's when the authorities start to impose controls/licencing/insurance/bans
[14:46] <AndyEsser> daveake: I suspect the majority of people who find their way onto an IRC channel are more of the "How/why does it work, and how can I do it for myself though"
[14:46] <AndyEsser> s/myself though"/myself" though
[14:47] <daveake> Yes, I think mostly they are. We have had exceptions.
[14:47] <AndyEsser> I have no doubt
[14:47] <AndyEsser> what's helium?
[14:47] <AndyEsser> :)
[14:47] <AndyEsser> Why do I need to a buy a parachute? I don't mind if I don't recover it
[14:48] <R34lB0rg> "i can save on helium by using hydrogen"
[14:49] <gonzo_> you could, but fopr some it would not be recommended

[15:01] <mfa298> of course just because people get emails for pull requests, doesn't mean they ever get actioned (I've had one open since september on an unrelated project)
[15:02] <eroomde> i hope i never action anything
[15:02] <fl_0> mfa298: sure. I didn't want daveake to crack heads on this :)
[15:03] <fl_0> just wanted to give feedback on the code because it obviously suffered from a bug
[15:03] <daveake> Well these ones just replictae what I did anyway, so no it won't get actioned
[15:03] <fl_0> that was preventing correct measurements

[15:04] <fl_0> at least with the changes that we made to the hardware
[15:06] <fl_0> we exchanged R12 with a 49k R
[15:06] <fl_0> and did some code redesign in order to get the current measurement working
[15:07] <LunarMobile> Btw I heard on February 20 people in Gelsenkirchen plan to fly a PITS
[15:07] <fl_0> LunarMobile: hu?
[15:07] <fl_0> interesting
[15:07] <fl_0> as that is right across the corner
[15:07] <LunarMobile> Cool
[15:08] <fl_0> where did you get that info from?
[15:08] <LunarMobile> Sorry don't know the URL by heart
[15:08] <LunarMobile> One sec
[15:08] <fl_0> sure
[15:08] <fl_0> np
[15:08] <habby> Any issue wth using CR2032 Lithium batteries to power Raspberry Pi A+? Have a UBEC voltage regulator.
[15:09] <habby> Also thinking of using a CR2032 to power another device, so not just for RPi...
[15:09] <habby> Obviously this will be at altitude...
[15:09] <LunarMobile> Friend told me yesterday
[15:09] <LunarMobile> http://wiki.n18.de/doku.php?id=n18-ballonmission:start
[15:09] <fl_0> hrhrhrhr
[15:09] <fl_0> that is us
[15:09] <fl_0> :D
[15:09] <LunarMobile> XD
[15:09] <mfa298> habby: are you sure you mean CR2032 i.e. one of the coin batteries
[15:10] <fl_0> I am just writing a few more lines for the wiki
[15:10] <fl_0> :D
[15:10] <AndyEsser> mfa298: might be able to make it work with enough of them :P
[15:10] <habby> Yes, mfa298: CR2032 with a dual button holder for RPi
[15:10] <Geoff-G8DHE-Lap> How long do you expect tha batteries to last ?
[15:11] <LunarMobile> Cool
[15:11] <habby> 3-4 hours, I guess.
[15:11] <mfa298> I think you'de be lucky to get the Pi booted before the CR2032 ran out of power (assuming it can provide enough current)
[15:11] <Geoff-G8DHE-Lap> 240maHr capacity 100mA idle current draw ??????
[15:11] <fl_0> LunarMobile: that was announced by the darc broadcast news a few days ago
[15:11] <Geoff-G8DHE-Lap> Let alone problems with low temperatures ??
[15:12] <fl_0> I am part of the mission team
[15:12] <LunarMobile> Ah cool
[15:13] <Ben-AstroSoc> my german is awful and i can read most of that, sweet
[15:13] <fl_0> Ben-AstroSoc: nice :)
[15:14] <fl_0> We want to involve some German people around this area
[15:14] <fl_0> that is why it is in German
[15:14] <fl_0> sorry :)
[15:14] <daveake> <fl_0> and did some code redesign in order to get the current measurement working
[15:14] <daveake> Didn't you just use the code that I gave to you ?
[15:14] <fl_0> basically yes. but we also changed the "FullRangeScale" values
[15:14] <daveake> ok fine
[15:15] <fl_0> but as I said: The values for the voltage measurement depend on what values you use for the voltage divider
[15:15] <fl_0> meaning R12 and R13
[15:16] <fl_0> we used 10k and 49k resulting in a ralation of 1:4.9
[15:16] <Geoff-G8DHE-Lap> habby, You might want to read this https://na.industrial.panasonic.com/sites/default/pidsa/files/panasonic-lithium-br2032-datasheet.pdf
[15:17] <fl_0> meaning a max. measurable value of 4.9 * 2.048V = 10.0352V
[15:17] <AndyEsser> "3v High Voltage"
[15:17] <AndyEsser> :)
[15:17] <Geoff-G8DHE-Lap> capacity reduced to 25% at -10c
[15:17] <fl_0> I don't know what values you use instead of the 10k/10k ones that where used originally
[15:18] <fl_0> LunarMobile: r u located in Germany?
[15:18] <habby> Thanks Geoff-G8DHE-Lap
[15:19] <habby> So, two of these, in a two-button holder with a UBEC voltage regulator (to give 5v) would not get me very far then?
[15:19] <Geoff-G8DHE-Lap> Nope.
[15:20] <AndyEsser> habby: no
[15:20] <AndyEsser> it was discussed a few weeks ago that a Pi 2 needs 1A
[15:20] <Geoff-G8DHE-Lap> Most people use these because of the temperature range http://data.energizer.com/PDFs/l91.pdf
[15:20] <daveake> "Pi 2 needs 1A" isn't actually true
[15:20] <AndyEsser> "with a USB peripheral"
[15:20] <habby> How about powering a different device (that draws a fifth of that power) with one CR2032?
[15:20] <AndyEsser> sorry
[15:21] <mfa298> habby: the other thing to look at is what current those batteries can provide, they're usually aimed at very low current draws (a few mA at most) so you might find they're not going to work unless you have a lot in parallel
[15:21] <daveake> I think the recommendation fo 2A or whatever comes from crappo chinese PSU's only managing a fraction of their rated curent
[15:21] <daveake> Some 1A ones can't do 1A into a short
[15:21] <Geoff-G8DHE-Lap> habby, its much nre the impact of low temperatures as well as the small capacity.
[15:22] <daveake> Also cheapo cables can drop enough voltage to stop the Pi from working
[15:24] <AndyEsser> daveake: still think he'd struggle with a CR2032
[15:24] <AndyEsser> ;)
[15:24] <daveake> haha yes
[15:27] <habby> Even if I used Vim? ;)
[15:27] <AndyEsser> :P
[15:27] <AndyEsser> I'm sure there's some archaic terribad command you can write in Vim to make it use Zero Point energy
[15:28] <Kryczek> /bin/ed
[15:28] <habby> I had a go with it and did the Kessel Run in less than twelve parsecs...
[15:29] <AndyEsser> BOC never responded to my request to set up an account
[15:29] <AndyEsser> *sigh*
[15:29] <AndyEsser> time to email them again methinks
[15:29] <Ben-AstroSoc> a parsec is a length of distaaaaaance
[15:29] <AndyEsser> Ben-AstroSoc: yes, all he means is he did it shorter distance ;)
[15:29] <Ben-AstroSoc> i just realised i emailed the CAA before christimas and still haven't heard back

[15:30] <AndyEsser> ;)
[15:30] <Ben-AstroSoc> i'm assuming CAA time is worse than Elon time
[15:30] <AndyEsser> for the record - I've yet to deal with the CAA so I'm just making this up for humourous effect
[15:30] <Ben-AstroSoc> eh it was nothing important
[15:30] <Ben-AstroSoc> was wondering if there were guidellines around max size of a HAB
[15:31] <Ben-AstroSoc> i have to choose a launch site soon so am gonn ahave to deal with them soon
[15:31] <AndyEsser> come to Wales ;)
[15:31] <AndyEsser> I know a field that needs testing as a launch site
[15:31] <AndyEsser> Was in the car with the gf on the weekend and said
[15:32] <AndyEsser> "Do you mind if... we just check out a field that's nearby... I just need to check phone reception and take some photos"
[15:32] <AndyEsser> I got the strangest look
[15:32] <Ben-AstroSoc> pfft
[15:32] <Ben-AstroSoc> nah in the next fortnight i need to choose a site and find a car
[15:32] <Ben-AstroSoc> have no idea where to begin with the former
[15:32] habby (~habby@host-92-16-186-164.as13285.net) left irc: Remote host closed the connection
[15:32] <Ben-AstroSoc> reckon i can blag one of the technicians to come with for the car xD
[15:34] <AndyEsser> haha
[15:34] <daveake> Ben-AstroSoc Here's how it works with the CAA. You apply. They do checks sometime (I don't know when) regarding the location, and *just* before the launch date they'll do the permission/exemption/notam. If you don't hear anything back like "sorry you can't launch from there" then you won't hear anything at all until the last working day prior to your
[15:34] <daveake> launch.
[15:35] <AndyEsser> Ben-AstroSoc: I suspect your "enquiry" has dismissed with the thought of "he can google that"
[15:35] <Ben-AstroSoc> maybe. i wonder if theres a suitable spot around malvern or something
[15:35] <daveake> My recommendation is that a few days before the launch day, you send a reminder saying that you do intend to launch
[15:36] Action: AndyEsser writes automated NOTAM submission app that hounds the CAA every days with reminders ;)
[15:36] <AndyEsser> every few days*
[15:37] <AndyEsser> Ben-AstroSoc: when did you say you were hoping to launch by?
[15:37] T-MaN (~thomas@217.21.233.78) left irc: Quit: Leaving
[15:37] <Ben-AstroSoc> within the 3 week period commencing march 21st
[15:37] <Ben-AstroSoc> so ~7-8 weeks
[15:38] <AndyEsser> cool
[15:38] <AndyEsser> are you hoping to recover?
[15:38] <Ben-AstroSoc> yeah
[15:38] <AndyEsser> On a weekend?
[15:38] <Ben-AstroSoc> more than likely
[15:38] <Ben-AstroSoc> i think one of the weeks in that launch window is the easter hols
[15:38] <AndyEsser> mind an extra body coming and witnessing?
[15:38] <Ben-AstroSoc> i mean you probably know what you're doing more than we will so sure
[15:39] <Ben-AstroSoc> more the merrier
[15:39] <AndyEsser> have yet to ever do a launch :)
[15:39] <AndyEsser> as it stands, will be doing my first launch without witnessing or partaking in one
[15:39] <AndyEsser> other than some YouTube vids from Steve Randall
[15:39] <Ben-AstroSoc> i've just read as many guides as i can find followed by picking you guy's brains if i want to confirm something
[15:39] <AndyEsser> But yea, if it's a weekend I'll load up my laptop and my SDR dongle and things and come down
[15:40] <AndyEsser> always happy to try and help recover as well sometime
[15:40] <Ben-AstroSoc> sure
[15:40] <AndyEsser> should look at getting the HAB preamp and a Yagi
[15:40] <AndyEsser> Open question to the channel - recommended Yagi's for HAB recovery?
[15:40] <Ben-AstroSoc> yeah we're starting to order kit this week
[15:40] <Geoff-G8DHE-Lap> Try to avoid going anywhere near one of these volumes especially during launch! http://360.g8dhe.net/HAB_Flights/airspace.kmz
[15:41] Action: AndyEsser downloads Google Earth
[15:41] <Ben-AstroSoc> don't have gEarth on this machine so will look later
[15:41] <AndyEsser> Amused that Photoshop attempted to open the file :)
[15:41] <daveake> AndyEsser You're welcome to come down here sometime to see how a launch works
[15:42] <AndyEsser> daveake: I'd very much appreciate that :)
[15:42] <AndyEsser> have friends in Bristol/Cardiff/Swansea as well, so at least I wouldn't have to drive down just for that
[15:42] <daveake> It's a quick way to answer a lot of questions you'd have
[15:42] <AndyEsser> daveake: when's your next one planned?
[15:42] <daveake> hahahahaha
[15:42] <AndyEsser> daveake: as long as you don't mind me basically being Donkey from Shrek with questions :P
[15:42] <daveake> when it's not windy not wet and I can get it to land on land
[15:43] <AndyEsser> Shall I just pack a bag and leave it in the car ;)

[15:46] <AndyEsser> daveake: guessing I should buy a bit of coax as well rather than just the 2" thing that appears to have...
[15:47] <Kryczek> daveake: ooooh I misread, my bad, I thought you were talking of another place on the South coast maybe, far from Bristol etc :)

[15:48] <daveake> You want 2-3m of coax, and a plug or plug/adapter to fit your radioSDR
[15:48] <AndyEsser> both have SMA
[15:48] <AndyEsser> need to check geners
[15:48] <AndyEsser> genders*
[15:48] <daveake> That length of cable isn't going to be very lossy so it won't matter much what you use
[15:49] <Geoff-G8DHE-Lap> Consider mounting a dongle actually on the aerial, saves too many leads flying about.
[15:49] <daveake> yeah that's definitely an option

[15:49] <AndyEsser> dongle on the antenna... then just a usb extension?
[15:50] <daveake> Just a longish USB cable
[15:50] <Geoff-G8DHE-Lap> that is one way as it getds rid of the co-ax lead.
[15:50] <AndyEsser> hmm
[15:50] <AndyEsser> but the SMA connectors are more secure than USB
[15:50] <daveake> I continue to stick with scanner or 817, but if you're using an SDR then that does make sense

[16:25] <Laurenceb> looks like Ps-58 is down :-/
[16:25] <AndyEsser> o0o found the tick box
[16:25] <Laurenceb> south indian ocean weather seems to always be bad
[16:26] <Geoff-G8DHE-Lap> Zoonm in and look in at angle, your probably to far out to see the volumes of airspace under control.
[16:27] <AndyEsser> nah, needed to tick the "airspace" checkbox on the left
[16:27] <AndyEsser> can see them now
[16:27] <Geoff-G8DHE-Lap> Yes that helps as well !

[16:28] <Laurenceb> they are getting amazingly accurate now

[16:39] <AndyEsser> daveake: will do - cheers
[16:39] <Geoff-G8DHE-Lap> Looks good to me! Ought to try sending a 3D view to CAA request!
[16:40] <AndyEsser> Geoff-G8DHE-Lap: ?
[16:40] <Geoff-G8DHE-Lap> When you put in for a NOTAM
[16:40] <AndyEsser> send the predictor track?
[16:40] <AndyEsser> or the 3d view with volumes?
[16:41] <LunarMobile> Yes Osnabrück
[16:41] <Geoff-G8DHE-Lap> Why not both turn them both on then you can see
[16:41] <AndyEsser> ha, didn't realise the predictor exported to Google Earth/KML

[16:44] <AndyEsser> depending on CAA margin of error

[16:48] <AndyEsser> seems to tick all the boxes (barring the tree in the middle....)

[16:52] <AndyEsser> Cool :)
[16:52] <AndyEsser> will look at doing that once I have the hourly set up :)
[16:52] <Geoff-G8DHE-Lap> Probably include time on it as wel just had a brief play.

[19:23] <criticalmass> Took my RTL-SDR dongle to work today (I work at RAF Odiham). Tuned to Odiham tower and got lots of comms straight away. After a little while listening, I started to pay attention to the messages. Nothing vortex (Chinook) related at all. Turns out, Bournemouth ATC use the same frequency for some London traffic so I was listening to airliners going overhead,

[21:34] <fl_0> Upu: thanks for adding to my pull request
[21:34] <fl_0> you say you changed R13 to 25k
[21:34] <Upu> nps didn't merge it as we are going with 25K
[21:35] <fl_0> jepp. got that
[21:35] <fl_0> but wouldn't it make sense to choose a greater value in order to be able to measure higher input voltages?
[21:35] <Upu> Max is 15V in
[21:35] <fl_0> the print on the board says taht could be up to 15V or so
[21:35] <Upu> yeah I think I did some maths and 25K was ok
[21:35] <fl_0> hhmmm
[21:36] <fl_0> we alsodid some maths :)
[21:36] <Upu> or may have done 7V :/
[21:37] <fl_0> jepp i guess
[21:37] <Upu> what did you use ?
[21:37] <fl_0> because the ADC converter can only measure up to 2.048V
[21:37] <Upu> yes
[21:37] <fl_0> if you use 10k/25k you get an input relation of 1:2.5
[21:37] <fl_0> so 2.5 times 2.048V
[21:38] <fl_0> so somewhat 5V max
[21:38] <fl_0> if my math is correct
[21:38] <fl_0> we use 10k/49k so our max input is 4.9 * 2.048V which makes 10ish V
[21:40] <fl_0> that was our math
[21:40] <fl_0> so if that is correct and you would want to measure up to 15V should R12 or R13 be in the 80k range to get a relation of 1:8 and therefore 8 * 2.048 = 16ish V?

[21:40] <fl_0> just thinking out loudly :)
[21:42] <Upu> yes
[21:42] <Upu> just resolution won't be as good in the normal range
[21:42] <Upu> normal ~ 7V
[21:43] <fl_0> jepp sure
[21:43] <Lunar_Lander> you want to connect a higher voltage battery so to speak?
[21:43] <fl_0> Lunar_Lander: the input voltage regulator accepts up to 15V
[21:43] <Lunar_Lander> ah
[21:43] <fl_0> it is not a must to use that
[21:43] <fl_0> :)
[21:43] <fl_0> just wanted to mention it
[21:43] <Lunar_Lander> true :)
[21:43] <fl_0> I guess people will be flying with batteries in the 6 to 7V range normally
[21:43] <fl_0> :)
[21:43] <Lunar_Lander> I selected a crazy TI regulator

[21:44] <Lunar_Lander> IIRC up to 30V in, 3.3V out
[21:44] <fl_0> jepp :)
[21:44] <fl_0> Upu: I just wanted to mention it
[21:44] <fl_0> In case you probably had some error in your math
[21:44] <Upu> no we appreciate it
[21:44] <Lunar_Lander> that was quite expensive I think
[21:44] <fl_0> Upu: okay :)
[21:59] <Lunar_Lander> I got a bit short sighted question
[21:59] <Lunar_Lander> why did no one send a normal hygrometer to mars yet? i.e. what we know as SHT21 for instance
[21:59] <Lunar_Lander> or was something like that done already?
[22:00] <Lunar_Lander> the Viking weather station measured p, T and wind as I found out
[22:01] <Vaizki> viking weather station stats: blood temperature, skull thickness, wave height and mead abv
[22:01] <Lunar_Lander> :D
[22:03] <MikeUoN> Isnt the mean temp on mars <-50C?
[22:03] <Lunar_Lander> true
[22:04] <MikeUoN> Oh this looks like it might explain nicely: http://elib.dlr.de/65665/1/Koncz_Characterisation_of_capacitive_humidity_sensors_under_Martian_pressure_and_temperatures_down_to_-120__%C2%B0C.pdf
[22:04] <MikeUoN> Cool topic!
[22:04] <Lunar_Lander> yea
[22:04] <Lunar_Lander> I was just thinking about the implication
[22:04] <Lunar_Lander> RH is a function of temperature after all
[22:06] <MikeUoN> fair
[22:06] <Lunar_Lander> well function of T and dewpoint at the same time
[22:06] <Lunar_Lander> the paper is interesting, thanks
[22:07] <Lunar_Lander> mentiones SHT75
[22:07] <MikeUoN> Whereabouts are you from again, LL?
[22:08] <Lunar_Lander> Osnabrück, northwestern germany
[22:08] <MikeUoN> Ah cool.
[22:09] <Lunar_Lander> :)
