[00:40] <Laurenceb> I'm so bored I'm reading http://en.wikipedia.org/wiki/Radio_masts_and_towers#Catastrophic_collapses
[01:02] <akawaka> Laurenceb: how do i measure the output impedance of something?
[01:03] <Laurenceb> thats something I've never understood
[01:04] <Laurenceb> maybe with a line of coax
[01:04] <Laurenceb> and a terminating resistor
[01:04] <Laurenceb> not equal to the line impedance
[01:05] <Laurenceb> so you have a standing and travelling wave
[01:06] <Laurenceb> examine your line with a scope ... ?
[01:13] <Laurenceb> or... just cut the end of your line
[01:13] <Laurenceb> so you get reflections, then look at the standing waves
[01:25] <Laurenceb> so they bounce up and down the line
[01:26] <Laurenceb> if you have impedance matching, there should be a perfect standing wave
[01:36] <akawaka> hmmm
[01:36] <akawaka> you measure the voltage drop across a load and a voltage drop without a load
[01:37] <akawaka> Z = ( R * ( V_unloaded - V_loaded ) ) / V_loaded
[01:37] <akawaka> http://www.bcae1.com/outptimp.htm
[01:49] <Laurenceb> I would use transmission line techniques for rf
[01:50] Action: Laurenceb is going to buy himself http://www.sparkfun.com/commerce/product_info.php?products_id=8238#
[01:50] <Laurenceb> soon as they are back in stock that is...
[01:52] <akawaka> i bought a 100mhz scope on ebay the other dya
[01:52] <Laurenceb> how much?
[01:52] <akawaka> $70 including shipping
[01:52] <Laurenceb> wow
[01:52] <akawaka> analog, not digital
[01:52] <Laurenceb> sure
[01:52] <akawaka> but it does have some measuring functions
[01:53] <akawaka> hope it will help me get a better understanding of analog stuff
[01:53] <Laurenceb> I'm sure it is good enough for getting your impedance correct
[01:54] <Laurenceb> you want signal from the output stage to bounce off the end of the cable then be fully adsorbed as it hits the output again
[01:54] <Laurenceb> *absorbed
[01:54] <Laurenceb> that will give you a pure standing wave
[01:55] <Laurenceb> you'll need a non integer wavelenght lenght of cable
[01:55] <Laurenceb> I'm just trying to remember... we did this as a lab a couple of years ago :D
[01:57] <Laurenceb> so stick your scope in lambda/2 away from the end of the cable and fiddle with your output stage until you see no signal
[02:11] <akawaka> lambda/2 ?
[02:14] <Laurenceb> half the wavelenght (in the cable)
[02:14] <akawaka> i see
[02:14] <Laurenceb> you understand why?
[02:14] <akawaka> why can't i use the method on that website?
[02:15] <Laurenceb> its rf
[02:15] <Laurenceb> it reflects all over the place and is generally horrible
[02:17] <akawaka> see, this will tell me if i'm imdepance matched
[02:17] <akawaka> but i'd like to know the output imdepance of the system first
[02:18] <akawaka> so i can create a filter and imdepance matching stage for it
[02:20] <Laurenceb> if you make a rough output stage
[02:21] <Laurenceb> then look at the waveform at a few points, you should be able to work out the impedance...
[02:21] <Laurenceb> you'll have an infinite series of terms as the signal bounces backwards and forwards
[02:23] <Laurenceb> pretty simple to work out
[02:24] <Laurenceb> so step 1, look at existing design to get a rough idea
[02:24] <Laurenceb> 2 measure the waveamplitude at several points and calaculate the impedance
[02:25] <Laurenceb> 3 reduild the matching stage to better match
[02:25] <Laurenceb> 4 measure at lambda/2 from end and tweak design
[02:25] <Laurenceb> and your done
[02:26] <akawaka> in changing it from 14mhz to 21mhz, not sure how much of a change that is
[02:27] <Laurenceb> quite a lot :P
[02:27] <Laurenceb> but manageable
[02:27] <Laurenceb> if it was 14 to 140 youd be screwed
[02:28] <akawaka> i don't even know which parts form the lpf and which parts are for impedance matching
[02:28] <Laurenceb> I'm not totally sure either :-/
[02:28] <Laurenceb> RocketBoy would be the guy
[02:29] <Laurenceb> but your actual impedance shouldnt change too much
[02:30] <Laurenceb> can you link me the piccy?
[02:31] <akawaka> http://web.mit.edu/bgelb/www/balloon/hfbeacon/pa.png
[02:33] <Laurenceb> fiddle with L103
[02:33] <akawaka> for the lpf?
[02:33] <Laurenceb> no matching
[02:34] <Laurenceb> make L103 less than required
[02:34] <Laurenceb> then use a ferrite rod and stick it in out of the coil
[02:35] <akawaka> i see
[02:36] <Laurenceb> http://www.midnightscience.com/formulas-Eqn004.gif
[02:36] <Laurenceb> http://www.midnightscience.com/formulas-calculators.html#formulas4
[02:37] <Laurenceb> use blue tack to hold the ferrite in, then measure the impedance with an LCR
[02:37] <Laurenceb> and desolder coil, then build a new one
[02:39] <akawaka> lcr?
[02:40] <Kornholijo> yo
[02:41] <Kornholijo> sup :D
[02:42] <Laurenceb> measures inductors capacitors and reistors
[02:43] <Kornholijo> im gonna pikcup arduio probablu
[02:43] <Kornholijo> arduino*
[02:44] <akawaka> you can't just correct one typo in that sentence and pretend we didn't notice the rest:)
[02:45] <Laurenceb> lol I cant even understand you
[02:45] <Laurenceb> something about ardudno
[02:46] <Laurenceb> as it will now be known as by me
[02:57] <Kornholijo> =(
[02:57] <Kornholijo> omgw yuo cnet undisrtaned my?
[02:57] <Kornholijo> lol
[02:58] <Kornholijo> maybe il'l get arduino or boarduino, who knows =(
[02:58] <Kornholijo> <Wtf wrong today..>
[03:07] Action: Laurenceb doesnt understand the point of arduino
[03:24] <akawaka> simple, works, supported
[03:26] <Laurenceb> true... maybe for prototyping
[03:47] <rcaron> akawaka: what freq is the output?
[03:50] <rcaron> i'm told to use an SWR and/or wattmeter and transmit into dummy load of various resistances
[03:50] <rcaron> max power / lowest SWR will tell you your impediance
[03:50] <rcaron> (this does assume no reactive component)
[03:51] <rcaron> alternatively, you could measure the voltage across said resistor to give you the same idea
[03:52] akawaka (n=akawaka@external.treyarch.com) left irc: Read error: 110 (Connection timed out)
[03:55] <Laurenceb> yes, if you have a SWR meter you could use that
[03:59] <rcaron> my fellow hams don't think cable splicing at various lambda points is a good idea. what's this TX based on?
[04:01] <Laurenceb> akawaka's design
[04:01] <rcaron> oh, totally custom

[04:42] <Kornholijo> Laurenceb: why dont you like arduino?
[04:43] <Laurenceb> using "raw" avrs is better
[04:44] <Laurenceb> wiki is back up
[04:44] <Laurenceb> but I cant use it properly
[04:44] <Laurenceb> its putting lots of extra lines in my code :-/
[04:46] <Kornholijo> :p
[04:47] <Laurenceb> arggg
[04:47] <Kornholijo> why "raw" avrs are better?
[04:47] <Kornholijo> arggg.
[04:47] <Laurenceb> cheaper, more flexible
[04:47] <Laurenceb> this is driving me mad
[04:47] <Kornholijo> "more flexible"?
[04:47] <Laurenceb> do I actually have to write a script to process it?
[04:47] <Laurenceb> nvm
[04:47] <Kornholijo> arduino has ftdi etc, you can program it via usb
[04:47] <Kornholijo> no need serial
[04:47] <Kornholijo> ,,_,,
[04:47] <Laurenceb> theres more important things to worry about
[04:48] <Kornholijo> eg?
[04:48] <Laurenceb> like wtf is wrong with my code
[04:48] <Laurenceb> theres extra lines appearing all over the place now
[04:48] <Kornholijo> grats :>
[04:48] <Laurenceb> wrong character set somewhere...
[04:49] <Laurenceb> maybe I should take a look with vi ....

[04:53] <Laurenceb> done it
[04:53] <Laurenceb> well reverted it
[04:55] <Laurenceb> argg
[04:55] <Laurenceb> pastebin does the same thing
[05:00] <Laurenceb> hmm I'm useless with shell scripts
[05:00] <Laurenceb> any ideas?
[05:05] <Kornholijo> wutcha posting?

[05:25] <natrium42> Kornholijo, platinum foil in return for gumstix?
[05:25] <natrium42> actually, i don't know how much platinum foil costs, nvm
[05:26] <natrium42> http://www.surepure.com/view_product.php?prodnum=1895
[05:26] <natrium42> $165 ouch
[05:27] <natrium42> probably don't need that kind of purity
[05:28] <natrium42> wow
[05:28] <natrium42> ok
[05:29] <natrium42> Kornholijo, ok, i *will* trade my gumstix for a 1"x1" platinum foil piece
[05:30] <Laurenceb> lol
[05:30] <Laurenceb> ok, code done
[05:31] <Laurenceb> I've made it a bit less RAM hungry and done the Timer1 access properly now
[05:31] <natrium42> /o\
[05:32] <Kornholijo> 1"x1"?
[05:33] <natrium42> 2.5 cm x 2.5 cm
[05:33] <Kornholijo> a
[05:33] <Kornholijo> why need pfoil?
[05:34] <natrium42> for electrolysis
[05:34] <Kornholijo> ;O?
[05:34] <Kornholijo> fuxor
[05:34] <Kornholijo> making H?
[05:34] <natrium42> yes
[05:34] <Kornholijo> what for :o
[05:34] <Kornholijo> ooh..
[05:34] <Kornholijo> evil :p
[05:35] <Kornholijo> will take much tho..
[05:38] <Laurenceb> natrium42: you see the way read_gyro() returns a pointer
[05:38] <Laurenceb> well would it be better for me to return a float?
[05:40] <Laurenceb> as if I return a pointer, I have to use a static float in the function
[05:41] <Laurenceb> and when I call read_gyro() I assign another float to *read_gyro()
[05:41] <Kornholijo> well the pointer points to a "static float", doesnt it?
[05:41] <natrium42> i would have "static float turn_rate;" at the top of the .c file some where
[05:41] <Laurenceb> so using a pointer wastes clock cycles and ram ?
[05:42] <natrium42> and remove the pointer
[05:42] <Laurenceb> but overall the best way would be to say float rate_gyro()
[05:42] <natrium42> wait, you are not using it anywhere
[05:42] <natrium42> wtf
[05:42] <Laurenceb> surely?
[05:42] <natrium42> yes
[05:43] <Laurenceb> its only used once anyway
[05:43] <Laurenceb> but it makes the code easier to read
[05:43] <natrium42> the compiler will likely optimize it away anyway
[05:43] <Laurenceb> ok
[05:43] <Laurenceb> well I might as well change it
[05:44] <Kornholijo> compiler will optimize it and it will be the same, i tguess.. (-O3?)
[05:44] <natrium42> http://rafb.net/p/KOlK0E67.html
[05:44] <natrium42> or you could just return that formula thing
[05:44] <natrium42> doesn't really matter as compiler is smart enough to optimize it
[05:45] <Laurenceb> right
[05:45] <Laurenceb> thanx
[05:45] <natrium42> np
[05:47] <Kornholijo> natrium42: what about avr32 for "flightcomputer"?
[05:48] <natrium42> sure, why not
[05:48] <natrium42> what are your requirements?
[05:48] <Laurenceb> AVR32 flightcomputer
[05:48] <Kornholijo> yep laurence

[05:49] <Laurenceb> about 150ma at 150MHz
[05:49] <Kornholijo> nice
[05:50] <Laurenceb> actually no
[05:50] <Laurenceb> the whole payload uses 190
[05:50] <Kornholijo> brb
[05:50] <Laurenceb> so with radio, three AVR's, leds, GPS
[05:50] <Laurenceb> its probably under 100ma for the board
[05:50] <Kornholijo> leds in the fc??
[05:50] <Kornholijo> wtf :O
[05:50] <natrium42> at 5V?
[05:51] <Kornholijo> i think 12
[05:51] <Laurenceb> no, 8V
[05:51] <natrium42> ah
[05:51] <Laurenceb> I bypassed the diodes
[05:51] <Kornholijo> 8v??
[05:51] <Kornholijo> wt..
[05:51] <Laurenceb> theres a switched mode step down
[05:52] <Laurenceb> it can take 7 to 20 volts or so
[05:52] <Kornholijo> o
[05:53] <Kornholijo> why python?
[05:53] <Laurenceb> quick and easy

[06:01] <Kornholijo> for ur projects n stuff
[06:01] <natrium42> i run a small online shop
[06:01] <Kornholijo> o
[06:02] <Kornholijo> :/
[06:02] <Laurenceb> ok
[06:02] <Laurenceb> done, I've neatened it up a bit
[06:03] <Laurenceb> the only thing I can see to be tidied up is my checksum function
[06:03] <Laurenceb> u08 size=strlen(c_buf); <-- theres a better way to do that isnt there?
[06:03] <Laurenceb> I can run the loop until I get a null character?
[06:04] <natrium42> let me see
[06:04] <Kornholijo> while(bb!='\0')?
[06:04] <natrium42> yes, you sure can
[06:04] <natrium42> :)

[06:12] <akawaka> yeah, i know, its a tough habit to break
[06:12] <akawaka> but it'll get you into trouble
[06:12] <natrium42> yah, it's not going to produce shorter code anyway
[06:13] <Laurenceb> that is a pretty cool checksum function now
[06:13] <akawaka> exactly
[06:14] <Kornholijo> hey akawaka
[06:14] <Laurenceb> well I'm pretty happy with that code now
[06:14] <Laurenceb> but no doubt I'll find more things to optimise
[06:14] <akawaka> hey Kornholijo
[06:15] <Laurenceb> and probably could carry on forever :D
[06:16] <Laurenceb> need to check the timer setup to make sure its sensible....
[06:18] <Kornholijo> what u guys use for radios? what band / tx power, etc?
[06:19] <Laurenceb> someone answer
[06:19] <Laurenceb> sorry I've lost the will to live... 434 MHz
[06:20] <natrium42> or is it 343 MHz!?!
