[07:28] <costyn> Upu: I'm not sure what I'm looking at in your image. The white smudge in the middle is condensation ?
[07:28] <Darkside> yes
[07:28] <UpuWork> http://imgur.com/a/SuYhY
[07:28] <Darkside> moon is on the lupper left
[07:28] <UpuWork> we are pretty sure its just lense flare
[07:29] <UpuWork> the moon is very faint on the picture I linked in the mail
[07:29] <costyn> that white spot?
[07:29] <costyn> very bright?
[07:29] <Darkside> looks like lens flare
[07:29] <Darkside> ISS wouldn
[07:29] <Darkside> wouldn't be that bright
[07:29] <costyn> agreed
[07:29] <fsphil> the ISS would be backlit in that shot
[07:29] <fsphil> it would be darker than normal
[07:30] <costyn> it's a lens flare, where the ccd has been overexposed
[07:30] <Darkside> UpuWork: did you shoot in 1080p?
[07:30] <costyn> was it a GoPro?
[07:35] <UpuWork> yes
[07:35] <UpuWork> 1080p
[07:35] <UpuWork> and yes was a go pro
[07:35] <UpuWork> cheers
[07:36] <UpuWork> I like Stellarium

[08:01] <daveake> morning
[08:01] <UpuWork> morning jcoxon
[08:10] <WillDuckworth> what's the numbers for the conf so far?
[08:11] <jcoxon> 17 on the latest list
[08:11] <jcoxon> but it might need to be updated
[08:11] <jcoxon> still space
[08:19] <jcoxon> WillDuckworth, you going to come?
[08:21] <UpuWork> he's on the list jcoxon
[08:21] <jcoxon> oh yeah
[08:21] <jcoxon> hehe
[08:23] <griffonbot> Received email: Graham Shirville "Re: [UKHAS] ISS Passes"
[08:25] <jcoxon> UpuWork, so i've been looking at that picture
[08:25] <jcoxon> do you know when it was taken?
[08:28] <UpuWork> yeah
[08:28] <UpuWork> the one with the moon in ?
[08:28] <UpuWork> was taken about 10 seconds before burst
[08:29] <jcoxon> the one you posted to the list
[08:29] <UpuWork> 13:54:59 ish
[08:29] <UpuWork> UTC
[08:30] <jcoxon> and i assume its teh white bob to the left of the big lens flare
[08:31] <UpuWork> frozen lense
[08:32] <UpuWork> it steamed up quite badly even though we had the anti misting strips in it
[08:32] <jcoxon> i see
[08:32] <jcoxon> fair enough
[08:33] <jcoxon> iss is overhead right now :-)
[08:35] <daveake> I wish pilots would look at the dates on a notam

[08:36] <daveake> but the notam was for sat/sun only

[08:37] <daveake> ooer
[08:37] <daveake> actually ....
[08:37] <daveake> .... it's the notam that's wrong :)
[08:38] <UpuWork> the NOTAM is for all week
[08:38] <UpuWork> haha

[08:41] <daveake> The permission also says 2 flights only
[08:41] <daveake> but damn, now I'm going to get calls all week :(
[08:42] <UpuWork> ask him to revoke it ?
[08:42] <daveake> Yup, about to
[08:42] <daveake> Ah, actually ....
[08:42] <daveake> ... the notm is correct it's got the schedule at the nottom
[08:42] <daveake> FROM: 14 Jul 2012 07:45 GMT (08:45 BST) TO: 22 Jul 2012 15:00 GMT (16:00 BST)

[13:39] <kokey> I wonder what would be the simplest way to get some rtl-sdr action on my mac
[13:39] <kokey> I had an ubuntu build with it and gnu radio going, running under vmware fusion on my mac
[13:39] <Darkside> i have gnuradio compiled on my mac
[13:39] <Darkside> macports handled most of the dependencies
[13:39] <Darkside> well, all, i think
[13:40] <kokey> apart from fusion's trial expiring, and ubuntu taking up loads of disk space, it didn't perform that well either
[13:40] <Darkside> i had to do some dodgyness to get gnuradio to look in the right places while compiling
[13:40] <kokey> it's ok, compiling gnuradio always has some tricks to it
[13:40] <Darkside> heh
[13:40] <Darkside> i had to disable one or two modules
[13:40] <kokey> hmmm, yeah maybe I should update xcode on my mac and go that route
[13:40] <nick_> I'd like to try out gnuradio on raspbian
[13:41] <kokey> I'm on snow leopard, hope it doesn't mean I have to upgrade OS first
[13:41] <nick_> Or more accurately I'd like someone else to try it...
[13:41] <Darkside> i don't think gnuradio has proper ARM optomizations yet
[13:41] <Darkside> kokey: i don't think you'll need to upgrade OS
[13:41] <Darkside> it'll possibly be easier on snow leopard

[13:42] <kokey> ah yeah I think I remember now, to install the iphone sdk required and xcode upgrade, my memory turned it into installing xcode requires an OS upgrade
[13:42] chris_99 (~chris_99@unaffiliated/chris-99/x-3062929) joined #highaltitude.
[13:42] <kokey> that's fine then, I managed to free up enough disk for an xcode upgrade now
[13:43] <Darkside> id you already have macports installed, you'll need to reinstall after upgrading xcode
[13:43] <Darkside> critical binaries (like.. gcc) are in different places in the new xcode
[13:43] <kokey> yeah, I have a macports install from early 2009 I think
[13:44] <kokey> I should really go that route
[13:44] <kokey> since I want to write my own stuff for the rtl-sdr
[13:45] <kokey> stuff that can be ported to the pi etc.
[13:45] <kokey> assuming I spend enough time on it
[13:45] <Darkside> the issue is more about gnuradio's backend stuff
[13:45] <Darkside> and whether its been optomised for ARM or not
[13:45] <Darkside> i think its being worked on
[13:46] <kokey> well gnuradio's a big beast, it would be nice to be able to put some specific things together that doesn't use it
[13:46] <Darkside> ahh but the problem is, its the gruel backend, which everything uses
[13:46] <kokey> though the best libs I've seen for all the gnuradio functions were commercial
[13:51] <kokey> ok I might be getting myself way too sidetracked here, the purpose really is to use the rtl-sdr to test if I set up the rfm22b up right
[13:51] <Darkside> hehe
[13:51] <kokey> too bad there isn't a simple tool for osx for that
[13:52] <MrScienceMan> i was wondering recently, if i can run a aprs igate on the pi
[13:52] <kokey> perhaps I'll borrow the girlfriend's netbook and install one of the windows things
[13:52] <Darkside> MrScienceMan: sure you can
[13:52] <Darkside> well
[13:52] <Darkside> if it had audio input you could
[13:52] <Darkside> or you could use an external TNC and a RS232 to TTL or usb converter
[13:52] <MrScienceMan> yeh, i was thinking using sdr
[13:52] <Darkside> ok thats getting a bit different then
[13:53] <MrScienceMan> yep
[13:53] <Darkside> that'd be SDR -> soundmodem
[13:53] <Darkside> which is probably a bit much for the rpi to handle
[13:54] <MrScienceMan> thats my concern, otherwise I can probably hook it to a handheld
[13:59] <kokey> I'm wondering what the potential is for an ISM band equivalent of APRS
[13:59] <Darkside> would be cool
[14:00] <Darkside> but you;d have to check the licensing on AX.25
[14:00] <Darkside> i know it can't be used for commercial use
[14:00] <Darkside> i was thinking of experimenting with an AX25 based system (though not with AFSK) using the rfm22b modules
[14:01] <Darkside> trying to make a little packet repeater netowrk with a few of them
[14:01] <kokey> ah yeah that's a good idea
[14:01] <Darkside> run them at 1200 baud, or lower
[14:01] <Darkside> probably lower
[14:01] <Darkside> around here i could probably get away with 100mW without anyone noticing
[14:01] <gonzo_> 300bd fsk on HF was common
[14:02] <Darkside> yeah
[14:02] <Darkside> but those modules won't go that low :P
[14:03] <gonzo_> 70 cm is low enough for civilised people
[14:03] <Darkside> nah i mean baud rate
[14:03] <Darkside> they don't seem to work below 500 baud
[14:03] <kokey> really?
[14:03] <Darkside> yeah
[14:04] <gonzo_> ah, understand
[14:04] <kokey> rx that is?
[14:04] <Darkside> i couldn't get gmsk to work below 500 baud
[14:04] <Darkside> yeah
[14:04] <daveake> Darkside: http://hackaday.com/2012/07/18/sending-a-raspberry-pi-to-130000-feet/
[14:04] <Darkside> hell, not even sure tx worked
[14:04] <Darkside> daveake: let the flood begin
[14:04] <gonzo_> if you are writing your own, there are peobably better protiocols than ax25
[14:04] <daveake> wellies on
[14:04] <WillDuckworth> nice one dave
[14:05] <Darkside> funny how they make it seem like the rpi was the main telemetry payload
[14:05] <Darkside> which is sure as hell wasn't
[14:05] <daveake> nope
[14:06] <Darkside> wheres the disclaimer on your blog post dave
[14:06] Action: daveake checks server
[14:06] <daveake> OK so far ... :)

[14:06] <Darkside> your*
[14:06] <WillDuckworth> [david]
[14:06] <Darkside> gonzo_: but i want to tie it directly into the linux kernel ax25 stuff
[14:07] Action: kokey checks out AX.25
[14:07] <daveake> edit fail I assume [Will]#
[14:07] <kokey> ah, based on X.25... sounds like a good idea
[14:08] <kokey> annoying if it's not allowed to be used outside of amateur use
[14:08] <WillDuckworth> daveake - did you supply power direct to the webcam or was there enough juice from the ports?
[14:08] <Darkside> i think its just non-commercial
[14:08] <Darkside> but not sure
[14:08] <Darkside> WillDuckworth: be bypassed the fuses
[14:09] <daveake> WillDuckworth It's in my blog :p
[14:09] <daveake> ^^ whs
[14:09] <WillDuckworth> thought that was the case
[14:09] <kokey> lemme see if I can ask ofcom
[14:09] <WillDuckworth> getting soldering iron out
[14:09] <daveake> Just got the SMPS modules today
[14:09] <gonzo_> in UK the prob is that the TNCs are not going to be type-approved kit. And commercial kit must all be approved
[14:09] <Darkside> daveake: you really should be a big disclaimer on there
[14:09] <Darkside> "if you use a rpi as your main telemetry payload, you're a bloody idiot"
[14:10] <Darkside> gonzo_: ism band though
[14:10] <Darkside> you can probably get away with it
[14:10] <gonzo_> I recon it's a free for all there as only the TX modules need to be approved
[14:11] <gonzo_> (there may not even be an approval spec, what use to be MPT specs in UK. Prob summut EU now)
[14:11] <Darkside> but yeah, my plan was to write some code to make my osiris board predent to be a TNC
[14:11] <Darkside> a KISS TNC to be exact
[14:11] <Darkside> pretend*
[14:11] <Darkside> and write anotuer bit of code to implement a simple digipeater
[14:12] <Darkside> and just use the GMSK modulation/demod on the rfm22b
[14:13] <gonzo_> some amsats use (or used to use) BSPK 1200bd for their downlinks
[14:13] <Darkside> yeah
[14:13] <Darkside> with a big enough antenna at one or both ends, you can do some nice stuff
[14:13] <gonzo_> not sure iof that was based on ax25 frames?
[14:14] <Darkside> but i'm thinking about making a tiny solar powered digipeater and sticking it up the top of a tall building
[14:14] <Darkside> with a 1/4 wave antenna
[14:14] <gonzo_> nice idea
[14:14] <Darkside> the board is already small enough
[14:15] <Darkside> won't take much more effort to get it powered off a lipo cell with a solar charger
[14:15] <gonzo_> prob with digi's was, there was only acks end to end. If data was lose part way, you had to try again
[14:15] <Darkside> yeah, its not perfect
[14:15] <gonzo_> there were nodes that did acking between each step on the link
[14:15] <Darkside> but i figure it'd be fun to play around with it
[14:16] <gonzo_> I wrote a spec for a self healing network for a project years ago. Using 458meg modems
[14:17] <gonzo_> where nodes would beacon and auto route packets via the most reliable path
[14:17] <gonzo_> shame it never went anywhere

[16:49] <Lunar_LanderU> hello
[16:49] <joelio> excellent.. usb dvb-t dongle arrived today. gnuradio and rtl-sdr built
[16:49] <joelio> Lunar_LanderU: hello
[16:51] <Lunar_LanderU> today I tried to run two analogue reference voltages on the arduino, 3.3V for my humidity sensor & 2.56V for the battery potential divider. I made two functions for each and included analogReference(DEFAULT) in the first function and analogReference(INTERNAL2V56) in the second one. I get plausible humidities but a battery voltage of 1.3V from the 3 battery pack. when I tried the other reference before without the humidity
[16:51] <Lunar_LanderU> sensor, I got correct values.
[16:51] <Lunar_LanderU> hi joelio
[16:52] <nick_> Why do you need to analog references?
[16:52] <nick_> two
[16:52] Action: nick_ can't seem to type today

[16:53] <Lunar_LanderU> the humidity sensor needs the 3.3V reference, while I was told that this reference may deviate when the batteries run low, thus I should use the 2.56 V or 1.1V reference for the batteries
[16:55] <nick_> How low does the battery need to get before the arduino can't maintain the 3.3V reference?
[16:56] <nick_> Is that not too low to even run the arduino?
[16:56] <Lunar_LanderU> good question
[16:56] <nick_> I mean, it runs most things at 5V, no?
[16:57] <Lunar_LanderU> this is a 3.3V arduino
[16:57] <nick_> OK
[16:59] <Lunar_LanderU> what I read is that you have to wait some time for the references to switch
[16:59] <Lunar_LanderU> but when I introduced a 1000 ms delay, that also did not change anything

[17:16] <Upu> yeah makes web browsing quicker
[17:16] <Upu> should help @ 40km
[17:17] <nick_> It might make a big difference for running SDR on it.
[17:17] <Upu> thats a point
[17:18] <Upu> I'll try it out
[17:18] <nick_> I assume that has a decent amount of division involved
[17:18] <jonsowman> fingers crossed
[17:18] <nigelvh> Supposedly it does better support of floating point
[17:18] <daveake> Sounds like a big improvement

[21:38] <Lunar_Lander> daveake, still here?
[21:39] <daveake> depends who's asking
[21:39] <daveake> Ah, you, well .....
[21:39] <daveake> :-)
[21:39] <daveake> wossup?
[21:39] <Lunar_Lander> :)
[21:39] <Lunar_Lander> how are you first of all?
[21:40] <daveake> Well I read that I'm "awesome", so "smug" is the answer
[21:40] <Lunar_Lander> oh ok
[21:40] <Lunar_Lander> well this afternoon I had the following problem
[21:40] <Lunar_Lander> today I tried to run two analogue reference voltages on the arduino, 3.3V for my humidity sensor & 2.56V for the battery potential divider. I made two functions for each and included analogReference(DEFAULT) in the first function and analogReference(INTERNAL2V56) in the second one. I get plausible humidities but a battery voltage of 1.3V from the 3 battery pack. when I tried the other reference before without the humidity sensor, I got correc
[21:40] <Lunar_Lander> t values.
[21:40] <Lunar_Lander> and I thought maybe you had an idea
[21:41] <daveake> Yes
[21:41] <daveake> First, you don't need 2 regerences
[21:41] <daveake> references
[21:41] <Lunar_Lander> OK
[21:41] <daveake> Just scale both voltages so they work with a single reference
[21:41] <Lunar_Lander> yea
[21:41] <daveake> Second, if you did, you probably need to add a delay after selecting a reference
[21:41] <Lunar_Lander> that I did
[21:42] <daveake> ok
[21:42] <Lunar_Lander> I added up to 1000 ms
[21:42] <Lunar_Lander> but that did not work
[21:42] <daveake> lots
[21:42] <daveake> ok
[21:42] <nigelvh> 3. If anything is connected to the reference pin then it's going to use that, and possibly damage the internal reference if it gets connected.
[21:42] <Lunar_Lander> someone told me that the 3.3V reference may become unstable when the batteries go down
[21:42] <Lunar_Lander> nigelvh, yeah, AREF is unconnected
[21:42] <daveake> That was me
[21:42] <Lunar_Lander> yea
[21:42] <nigelvh> Good deal.
[21:42] <Lunar_Lander> thus the contraption with the 2 references
[21:43] <Lunar_Lander> because the thing is
[21:43] <daveake> You do NOT need 2 references
[21:43] <Lunar_Lander> I thought of having the reference globally at 2.56
[21:43] <daveake> Just do the scaling
[21:43] <Lunar_Lander> but then the humidity sensor needs the voltage divider
[21:43] <fsphil> avr has a built in vref of 1.1 or 2.2v
[21:43] <daveake> Do the maths for the scaling
[21:43] <Lunar_Lander> and somehow it doesn't like that
[21:43] <Lunar_Lander> yea
[21:43] <Lunar_Lander> when I add a voltage divider to the humidity sensor, the reading becomes static
[21:43] <daveake> Remember that the available references vary according to which processor you have
[21:44] <Lunar_Lander> it doesn't react on breathing on it anymore
[21:44] <Lunar_Lander> yea
[21:44] <daveake> Well you did it wrong
[21:44] <Lunar_Lander> on the mega I got 1.1V and 2.56V
[21:44] <fsphil> daveake: you also got called a genius
[21:44] <fsphil> so you're going quite well

[21:44] <nigelvh> Lunar_Lander, you probably can't use a voltage divider on the 4030, the output from that is VERY low current.

[21:45] <Lunar_Lander> yes
[21:45] <daveake> I take back everything I ever said about journos :p
[21:45] <fsphil> lol
[21:45] <Lunar_Lander> I got OpAmps today
[21:45] <Lunar_Lander> shall I try to make a voltage follower?
[21:45] <nigelvh> Using an opamp may be a better solution.
[21:45] <daveake> OK if it's high impedance then yes, you could use an op amp
[21:45] <Lunar_Lander> yea
[21:46] <Lunar_Lander> but I need to ask one thing
[21:46] <Lunar_Lander> if the reference is set to 2.56V, it says 2.56V = 1023 right?
[21:46] <daveake> So I think what you did was use resistors too low in value so you just dragged the voltage down
[21:46] <daveake> yes
[21:46] <Lunar_Lander> yeah, wait
[21:46] <nigelvh> Yes
[21:46] <Lunar_Lander> what did I use
[21:46] <Lunar_Lander> let me think
[21:46] <Lunar_Lander> I think I did use resistors not much bigger than 10 k
[21:46] <Lunar_Lander> that was not good?
[21:47] <nigelvh> That may be too much for the 4030
[21:47] <daveake> What's the impedance of the source?
[21:47] <Lunar_Lander> of the sensor?
[21:47] <daveake> yes
[21:47] <Lunar_Lander> good question :S
[21:47] <daveake> Well ....
[21:47] <daveake> .... if you just add components without knowing that stuff ....
[21:47] <daveake> ... shit happens
[21:47] <Lunar_Lander> ohh
[21:48] <Lunar_Lander> but I see that the current is 200-500 microamperes
[21:48] <daveake> Electronics is more than just wiring A to B (though sometimes it is that easy)
[21:48] <Lunar_Lander> yes
[21:48] <Lunar_Lander> and I usually read the datasheets
[21:48] <daveake> good
[21:48] chris_99 (~chris_99@unaffiliated/chris-99/x-3062929) joined #highaltitude.
[21:48] <nigelvh> The datasheet in this case doesn't list the output impedance.
[21:49] <nigelvh> Though it does list the normal current consumption as 200uA at 5V.
[21:49] <Lunar_Lander> yes
[21:49] <daveake> Always start with the datasheet
[21:49] <daveake> even if it isn't complete
[21:49] <Lunar_Lander> yes
[21:49] <Lunar_Lander> nigelvh, that gives 25 kOhms on my calculation
[21:50] <daveake> Wrong calc
[21:50] <nigelvh> Assuming that all 200uA comes out the output, which isn't the case.
[21:50] <daveake> You could have something using 200uA at 5V with a very low impedance. Current consumption with nothing connected tells you very little
[21:51] <Lunar_Lander> yea
[21:51] <daveake> A voltage regulator might consume 0.1mA normally, yet be able to deliver amps. The idle or "quiescent" current tells you nothing at all about the output impedance.
[21:51] <Lunar_Lander> yes
[21:51] <Lunar_Lander> true
[21:52] <Lunar_Lander> I forgot that, sorry
[21:52] <nigelvh> Also, the two 10k resistors in the divider with the device outputing 3V would suck down 150uA. While normally not a lot, in this case it's rather larger.
[21:52] <Lunar_Lander> yes
[21:53] <Lunar_Lander> I used the one online calculator to calculate what resistors I need to get 3.3V to 2.56V
[21:53] <daveake> If it doesn't tell you what you need ...
[21:53] <Lunar_Lander> and it said 3k and 10 k
[21:53] <daveake> ... measure it
[21:53] <Lunar_Lander> but you said those small resistors are not good
[21:53] <daveake> Take output. measure voltage. Add resistor load. measure again. then maths
[21:53] <Lunar_Lander> yes
[21:54] <daveake> Good tools: Multimeter. Brain.
[21:54] <Lunar_Lander> yeah
[21:54] <Lunar_Lander> got both
[21:54] <daveake> Poor tools: Internet
[21:54] <Lunar_Lander> ok
[21:54] <Lunar_Lander> so I measure what the voltage output is first
[21:54] <daveake> You're in good shape then :)
[21:55] <Lunar_Lander> ok :)
[21:55] <nigelvh> Rather, the internet alone is a poor tool. Internet + Brain is an excellent tool.
[21:55] <Lunar_Lander> I just want to make sure to understand it
[21:55] <daveake> I'll reprhase: Lunar, you're very capable of figuring this stuff out for yourself
[21:56] <daveake> Maybe you need a bit more confidence that that is the case?
[21:56] <Lunar_Lander> yea maybe
[21:56] <daveake> :)
[21:56] <daveake> That's the attitude :)
[21:56] <Lunar_Lander> :)
[21:56] <Lunar_Lander> sometimes I struggle to find the start though
[21:56] <Lunar_Lander> that is my problem I think
[21:56] <nigelvh> Mostly it just comes with practice.
[21:56] <Lunar_Lander> yea
[21:57] <nigelvh> I couldn't tell you how many things i've screwed up, or busted, or released the magic blue smoke from, or simply just didn't get the results I wanted.
[21:57] <Lunar_Lander> yea

[21:57] <daveake> It's OK, I was staring at circuit diagrams when I was 10, wondering WTF was going on
[21:57] <Lunar_Lander> yea
[21:57] <daveake> Lots of smoke and sparks and melted components since then
[21:57] <Lunar_Lander> yea
[21:58] <Lunar_Lander> so far I destroyed a LED and a MOSFET
[21:58] <daveake> That's nothing
[21:58] <Lunar_Lander> and damaged a voltage regulator
[21:58] <nigelvh> I did similarly. The gal at the local radio shack would save broken VCR recorders and whatnot people would bring in. And then I'd take them apart.
[21:58] <daveake> I once built a circuit on vero ...
[21:58] <daveake> ... some processor stuff one side ...
[21:58] <daveake> ... and a power reg etc the other side ...
[21:58] <daveake> ... and I cut all the tracks between components ...
[21:59] <daveake> ... except the tracks between one side and the other ..
[21:59] <Lunar_Lander> ohhhh
[21:59] <daveake> That board chained on to another
[21:59] <daveake> Everything was destroyed

[21:59] <daveake> And I'd spent MONTHS on it
[21:59] <Lunar_Lander> oh
[21:59] <Lunar_Lander> like this: https://www.youtube.com/watch?v=F-efQbRVZrs ?
[21:59] <daveake> So now, when you blow an LED, laugh at me :D
[22:01] <nigelvh> I've done nearly exactly that. Though it was an ancient computer and monitor. Had them both plugged into wall power, and went to plug in the monitor cable to the computer and it decided to arc weld the DB25 off.
[22:02] <Lunar_Lander> oh
[22:03] <nigelvh> Needless to say it scared the s*%^ out of me.
[22:03] <nigelvh> So, I scrapped that computer and built a trebuchet instead.
[22:03] <daveake> lol
[22:04] <Lunar_Lander> XD
[22:04] <Lunar_Lander> one more stupid question
[22:04] <Lunar_Lander> what exactly do you mean with the resistor load?
[22:04] <daveake> It's a resistor
[22:04] <nigelvh> Connected to ground.
[22:05] <Lunar_Lander> from the output?
[22:05] <daveake> So it's "loading" the output
[22:05] <daveake> yes
[22:05] <Lunar_Lander> like a pulldown?
[22:05] <daveake> yes
[22:05] <Lunar_Lander> ah
[22:05] <Lunar_Lander> thanks
[22:05] <daveake> The output impedance of your device forms a potential divider (you know about those) with the resistor
[22:05] <Lunar_Lander> yea
[22:06] <daveake> So with the maths you've done before, you can calculate the impedance by measuring the voltage before and after you add the load resistor
[22:06] <nigelvh> (Assuming the voltage isn't zero or the same as before when you add the resistor)
[22:06] <Lunar_Lander> yea
[22:06] <daveake> So if the datasheet doesn't tell you (like you said) you can measure it, indirectly
[22:07] <daveake> yup
[22:07] <Lunar_Lander> thanks
[22:07] <daveake> A good rule of thumb would be to measure the voltage without a load, then add different resistors till the voltage drops to about half
[22:08] <Lunar_Lander> OK
[22:08] <nigelvh> Alright, time to go home. Chat with you guys later. Congrats daveake and good luck Lunar_Lander.
[22:09] <daveake> ta :)
