[02:59] <kristianpaul> Is it valid to asuume:
[03:00] <kristianpaul> 0, 1, -0, -1 signed (int/unint etc..)
[03:00] <kristianpaul> 00, 01, 10, 11 2bit sig/mag
[03:01] <kristianpaul> i dont find where the chip manufacturer specify specs for the internal ADC
[03:20] <kristianpaul> hum page 11 looks very ilustrative :)

[04:12] <kristianpaul> humm akos/borre matlab code is just for complex?!Ahh
[04:13] <kristianpaul> well, acording to gps EVB manual there is a "debug" that activate the real out and disable the propietary downconverter sinde the chip :D..
[04:14] <kristianpaul> i need to check how this signal looks, is not very clear from the datasheet...
[04:14] <kristianpaul> but!! does it worth the try of complex?
[04:14] <kristianpaul> real i mean
[04:15] <SpeedEvil> You can - pretty much - treat complex as a sequence of reals.
[04:15] <kristianpaul> yeah but, it still to work?
[04:16] <SpeedEvil> I, Q, -I,-Q
[04:16] <SpeedEvil> Or similar
[04:17] <SpeedEvil> To get a similar phase resolution to a complex signal, you need a real signal at 4* the rate
[04:17] <kristianpaul> Gp2021 datasheet said, In Complex_lnput mode a single In-Phase Carrier DCO
[04:17] <kristianpaul> output is used in both mixers since the input signal is
[04:17] <kristianpaul> already in I and Q form.
[04:17] <kristianpaul> and i like how sounds..
[04:19] <SpeedEvil> There are typically two ways to do it - you eaitehr have a signal chain with seperate I and Q, and then merge them at the end at low frequency, to get a complex result, or you do it complex all the way through.
[04:19] <kristianpaul> yeah, thats actually what happen with the SiGe4162, "The data is decimated and filtered by 4 to give 2.048 MSPS data, and serialized."
[04:24] <kristianpaul> so this sige chip looks good for making things easier the processing at low rates

[04:39] <kristianpaul> complex all way trough, looks like this i think http://home.earthlink.net/~cwkelley/receiv5.gif
[04:40] <kristianpaul> also hard/soft correlators like namuru and gp2021 can do complex way
[04:40] <kristianpaul> but i tought SoftGNSS could too,

[10:17] <fsphil> big chip eh? :)
[10:18] <Lunar_Lander> yeah
[10:18] <Darkside> go SMD :-)
[10:18] <fsphil> that's what I used on hadie - next time it will be an soic version
[10:18] <Lunar_Lander> yes
[10:18] <Lunar_Lander> I need to know
[10:18] <fsphil> or whatever format the little square is -- tfga or something
[10:18] <Darkside> TQFP
[10:18] <Lunar_Lander> because if I order under 25 euro, they charge 5 euros of some kind of fee
[10:18] <Darkside> the atmega328p is a TQFP-32
[10:18] <Lunar_Lander> mixio: that doesn't affect your cost of course
[10:19] <Lunar_Lander> you only pay for 3 xtals and 3 sockets
[10:19] <fsphil> Lunar_Lander, there is a smaller version of the 644p -- half the memory and flash, same pins so compatible
[10:19] <fsphil> might be cheaper
[10:19] <Lunar_Lander> what is it called?
[10:19] <SpeedEvil> http://www.youtube.com/watch?v=-IwmUwkULxQ&feature=related ...
[10:19] <SpeedEvil> Why?
[10:20] <SpeedEvil> I mean - I can see the point of scale RC.
[10:20] <SpeedEvil> But 70%?
[10:20] <fsphil> atmega 324P I think
[10:20] <fsphil> but double check that
[10:20] <Lunar_Lander> ah
[10:20] <Lunar_Lander> thanks fsphil
[10:21] <Lunar_Lander> mixio: if you read me
[10:21] <Lunar_Lander> I am going to have lunch now
[10:21] <fsphil> I only used the 644p because I didn't know how big the ssdv stuff would be

[13:50] <cuddykid> v v thin though
[13:50] <cuddykid> thats the nichrome thats thin
[13:51] <Zuph> Well, if you can't comfortably shorten the nichrome, then more batteries is probably the way to go :)

[15:37] Action: SpeedEvil presses the paypal button on 600W of dodgy solar cells.
[15:37] <SamSilver> we use it here all the time - I thought it was only a South African saying
[15:38] <SamSilver> SpeedEvil: you still going to come in @ 50p/w ?
[15:39] <fsphil> I knew I should have waited before getting PV panels
[15:39] <fsphil> they've come down a fair bit since then
[15:39] <SpeedEvil> Well - the cells themselves are 20p/w.
[15:40] <SpeedEvil> So maybe a bit under that.
[15:40] <LazyLeopard> SamSilver: UK ;)
[15:40] <SpeedEvil> Rather a lot of labour, and it would make more sense getting unbroken cells probably.
[15:40] <LazyLeopard> SamSilver: ...but born & bred in Kenya...
[15:40] <SpeedEvil> But I figure if I can work out how to make panels rapidly from these, I can about half my cost.
[15:40] <SamSilver> ahhh!
[15:41] <SpeedEvil> You can get unbroken cells at ~35p/W in 1kW
[15:41] <SpeedEvil> But to do it 'properly' - the encapsulant costs you about that again, and then you have the cost of glass, which maybe adds a few percent more.
[15:44] <fsphil> I've a panel where the glass is shattered, if you wanna buy it? :)
[15:44] <fsphil> the actual cells are fine
[15:44] <SpeedEvil> Shipping is another massive issue.
[15:45] <SpeedEvil> You can get 'solar laminate' - which are the bare cells laminated onto the glass - for around a dollar a watt - from some vendors in the states.
[15:45] <SpeedEvil> (or at least you could - that website went dead)
[15:45] <SpeedEvil> At that price - I wouldn't be bothering DIYing.
[15:45] <SpeedEvil> But shipping that seems utterly impossible.
[15:45] <SpeedEvil> Oh - on a related matter.
[15:46] <SpeedEvil> Anyone know of any teeny air pumps?
[15:46] <SamSilver> how teeny?
[15:46] <SpeedEvil> A litre a minute - something of that order.

[15:46] <SpeedEvil> I'm overcoming bad panel construction with ugly hacks.
[15:46] <SamSilver> preasure?
[15:46] <SpeedEvil> negligable
[15:47] <SamSilver> I am thinking perestolic (spellin)
[15:47] <SpeedEvil> peltier outside panel - circulate air from inside panel over peltier - drop out the occasional ice cube.
[15:47] <SamSilver> lol
[15:48] <SamSilver> what about letting convection work for you
[15:48] <SpeedEvil> Possible - however the panel is ~10mm deep - and maybe up to a couple of meters long.
[15:50] <SpeedEvil> The basic problem is I'm being silly. And considering instead of making the front out of nice glass which is not porous, making it out of plastic, and sacrificing the 20% efficiency and other factors for - comparative - unbreakability.
[15:50] <SamSilver> is turning it around - making lenght now the height
[15:50] <SpeedEvil> And lightness when installing.
[15:50] <SamSilver> just brainstorming here
[15:50] <SpeedEvil> I'm considering a 2m*2m panel.
[15:50] <SamSilver> bugger it is square

[18:18] <SpeedEvil> mixio: I was meaning the upcoming possible exit of greece from the euro
[18:18] <fsphil> "We deliver everywhere... at the same time"
[18:19] <fsphil> they also require a credit check
[18:19] <mixio> SpeedEvil: i dont know. I dont care. Tomorrow i was about to go to neighboor country to see my ex-girl from there and tomorrow they have strike on borders.

[18:19] <mixio> I hate them all
[18:20] <SpeedEvil> Horrible 'austerity' measures though.
[18:20] <mixio> distance is soo little and because of stupid border thing i cant go there!
[18:20] <mixio> i live in a prison
[18:20] <mixio> i cant travel 250km away from my home
[18:20] <fsphil> or a delivery service .. "N.Ireland to Yorkshire in 3 hours* ... some tree climbing may be required"
[18:20] <Dan-K2VOL> mixio they shut the water off to your house?

[18:21] <SpeedEvil> Soon, I shall be independant of the grid!
[18:22] <SpeedEvil> (well - to a very - very limited extent)
[18:22] <mixio> SpeedEvil
[18:22] <mixio> answer my previous question plz
[18:22] <SpeedEvil> As in just enough to keep my freezer going, and internets
[18:22] <SpeedEvil> More in summer?
[18:22] <SpeedEvil> What question
[18:22] <Randomskk> SpeedEvil: yea I have a UPS for my desktop, I can get whole seconds independent of the grid :D
[18:22] <Randomskk> assuming my screen provides enough lighting, and I guess I still rely on the telephone grid or cellular network
[18:23] <SpeedEvil> Randomskk: I'm planning on getting ~600W of panels up and running soon. This should even in the worst days provide about enough power for freezer +10W
[18:23] <fsphil> we need an HF internet
[18:23] <Randomskk> nice
[18:23] <mixio> [21:18] <mixio> SpeedEvil what if i send you the money from paypal and you pay them and tell them to send the module to my addr?
[18:23] <SpeedEvil> mixio: Is there a nice online store?
[18:24] <mixio> what store?
[18:24] <SpeedEvil> Where I can order stuff - or how does it work
[18:25] <mixio> ah yes sure. we got many.
[18:25] <mixio> but most are start to close day by day
[18:25] <cuddykid> woo.. hot wire cutter working a treat :D

[18:26] <fsphil> nice cuddykid
[18:26] <mixio> i dont understand u
[18:26] <cuddykid> is there any way to avoid the sqiggly line as the wire is so thin it moves about a little from side to side when cutting so its not entirely flat cut
[18:27] <SpeedEvil> mixio: Sorry - I'm doing other stuff - so not tracking properly
[18:27] <SpeedEvil> cuddykid: More tension, or less speed
[18:27] <fsphil> tension?
[18:27] <mixio> anyway
[18:27] <SpeedEvil> cuddykid: Also - fix the wire close to the points of entry
[18:27] <mixio> i may find some other brit guy here to help me with that!
[18:27] <cuddykid> theres a fair bit of tension, will try fixing wire and moving slower! thanks

[20:46] <Upu> weather ?
[20:46] <Lunar_Lander> what wattage do you need for the resistors in your tutorial?
[20:46] <Upu> oh nothing at all
[20:46] <Lunar_Lander> 1/2 or 1/4 W?
[20:46] <Lunar_Lander> ah
[20:46] <Upu> the small ones I'm using are 1/4w and the larger ones 1/2w
[20:46] <Lunar_Lander> http://www.sparkfun.com/products/9258
[20:46] <Lunar_Lander> is this good?
[20:47] <Upu> well if you want lots
[20:47] <Upu> yes :)
[20:47] <Lunar_Lander> because the resistors at farnell are pretty expensive I think
[20:47] <Lunar_Lander> and you only get them in lots of 5
[20:49] <Upu> I think I just bought a few from Maplins
[20:49] <Lunar_Lander> or are the resistors of TE Connectivity good?
[20:49] <Upu> TE ?
[20:49] <Lunar_Lander> http://uk.farnell.com/jsp/search/productdetail.jsp?sku=1265081
[20:49] <Upu> no idea to be honest
[20:50] <Upu> I just used 5% carbon film I think
[20:50] <Lunar_Lander> ah OK
[20:50] <Upu> I forgot to mention the NTX2 has a build in 100k resistor on the input pin
[20:50] <Upu> so if you decide to chuck it in a circuit sim to work it out don't forget that
[20:50] <Lunar_Lander> yes
[20:51] <Lunar_Lander> yeah
[20:51] <Lunar_Lander> but your tutorial works "as is"?
[20:51] <Upu> yep
[20:52] <Lunar_Lander> good
[20:52] <Upu> theres lots of ways to do i
[20:53] <Upu> it
[20:53] <Upu> that is just one of them and gives people a starting point
[20:53] <Lunar_Lander> yea
[20:54] <Upu> you could just buy a few variable resistors and get the circuit right and then measure the resistance and move to fixed values
[20:54] <fsphil> ^^ good idea
[20:54] <Lunar_Lander> yeah

[22:10] <mixio> Radiometrix sucks with its payment methods. For a 15GBP radio module it will charge me some 40 euro.
[22:10] <mixio> Propably more because of bank transfers.
[22:11] <Lunar_Lander> damn
[22:11] <mixio> So I need someone from Brit to get me the module.
[22:11] <Lunar_Lander> mixio sorry that I didn't respond
[22:11] <mixio> Lunar_Lander: nevermind
[22:11] <Lunar_Lander> I can tell you the price when farnell gets the order done
[22:11] <Lunar_Lander> is that OK?
[22:11] <mixio> ok
[22:11] <Lunar_Lander> it should be around those 12 euros
[22:12] <mixio> Lunar_Lander: I just have money in paypal and i can send right now.
[22:12] <mixio> fsphil: my plan is to send you all the required money, module+shipping
[22:13] <mixio> fsphil: you buy it and when u get it you send it to me with simple mail service just like u did with crystals.
[22:13] <mixio> fsphil: how do u think? I put you in much trouble?
[22:13] <Lunar_Lander> mixio oh ok
[22:14] <Lunar_Lander> mixio I hope that they'll get it done tomorrow
[22:16] <fsphil> would probably cost about 35 EUR in the end, you wouldn't be saving much
[22:17] <mixio> Lunar_Lander: yea
