[17:11] <cuddykid> hi guys, i've got my ntx2 and going to start interfacing the radio with arduino soon. However, before I start i've got a question! With reference to -> http://www.pegasushabproject.org.uk/wiki/doku.php/ideas:notes how do the resistors from pins 9 & 10 work in providing correct voltage? As if I'm thinking right isn't this just a potential divider??! If so surely those values given an input of 3V would give wrong values (around 1V and 2V) for o
[17:11] <cuddykid> when we want around 0.9V and 1.2V correct?? Thanks

[17:13] junderwood_ (~John@adsl.jcu.me.uk) left irc: Read error: Connection reset by peer
[17:24] <SpeedEvil> One is 22k, one is 26k.
[17:24] <DanielRichman> cuddykid, disregarding any effect the transmitter might have on the divider, the total resistance is 48.4K and the supply voltage is 3v3. I forget which way around it is, but to do one tone you set pin 9 High and pin10 low (or the opposite). With 9HI 10LOW, the output would be 3.3x(26.4/48.4) = 1.8; 9LOW 10HI output is 3.3x(22/48.4) = 1.5
[17:24] <SpeedEvil> If you drive them one way round - 9+ and 10- - then you get about 1.6
[17:24] <SpeedEvil> The other way about 1.4
[17:25] <SpeedEvil> something like that
[17:27] <cuddykid> ok, thanks guys; so just to clarify, the voltage given doesn't need to be ~0.9V and ~1.2V it can be ~1.5V and ~1.8 provided you get around 0.3V difference?
[17:29] <DanielRichman> well the relationship between voltage and frequency produced isn't linear iirc
[17:29] <DanielRichman> but basically yeah. Go for it. That design has been tested by jcoxon many times
[17:29] <DanielRichman> breadboard it if you want, cuddykid
[17:29] <cuddykid> yeah, ok, will do!
[17:30] <cuddykid> is it possible to use the 5V output from arduino with potential divider to get shift or does it need to be a lower voltage so ~1 to 2V?
[17:32] <DanielRichman> cuddykid, yeah we powered our payload on 5v
[17:32] <DanielRichman> let me go grab the schematic
[17:33] <cuddykid> danielrichman: ok, thanks
[17:33] <DanielRichman> http://alienproject.files.wordpress.com/2009/06/radiometrix-circuit-diagram.png
[17:34] <cuddykid> got it! .. how come you've got a 10K resistor across TXD and GND? sorry, i'm a complete newbie!
[17:36] <DanielRichman> when one pin is +ive and the other -ive, the resistor on the pin that is LOW is in paralell with the 10K, reducing its value and therefore lowering the output voltage
[17:36] <DanielRichman> if you divide 3v3 you can get it to centre around 1.5V. Potential dividing 5v would result in something centred around 2.5 which is wayy out

[17:37] junderwood__ (~John@adsl.jcu.me.uk) joined #highaltitude.
[17:37] <DanielRichman> whether you're sending a mark or a space the 10K pulls the output down, resulting in some rtty centred around 1.2
[17:37] <DanielRichman> cuddykid, you definitely want to breadboard that design before you solder anything

[17:51] <cuddykid> alot of my modules require 3.3v, would it be ok if I just used the 3.3v output from arduino or would that overload it or are there any problems that anyone could think of?
[17:52] <DanielRichman> cuddykid, the 3v3 output from the arduino is 50mA max I think. It's not too difficult to get a 3v3 LDO regulator or some other (more efficient) means of regulation
[17:52] <DanielRichman> the 3v3 output is actually from a pin on the FTDI chip
[17:52] <DanielRichman> cuddykid, which modules?
[17:52] <cuddykid> urm, lassen iQ, preferably the ntx2 and theres another i think, can't think off the top of my head!
[17:53] <cuddykid> but the main one is the lassen with ntx2 being preferable
[17:53] <DanielRichman> the lassen will munch quite a bit of power. I'd put an extnernal regulator in

[17:54] <DanielRichman> the ntx2 it doesn't matter cuddykid; as you can see from the schematic I linked we ran ours from +5V
[17:54] <cuddykid> yeah, i see, it looks complicated! is it in practice? (thats running it off 5v)
[17:55] <DanielRichman> NTX2? the schematic I linked has the same number of components as running jcoxons 3v3 design
[17:56] <cuddykid> yeah, its just the 10K resistor between TXD and GND which looks the hard bit! soldering and everything :/
[17:57] <DanielRichman> cuddykid, you going to make a pcb or build it on stripboard?
[17:57] <cuddykid> stripboard was planned, but if PCB will be easier i'll probably go with that.. what do you think?
[17:58] <DanielRichman> PCBs are great :)
[17:59] <DanielRichman> cuddykid, do you have to pcb making kit?
[17:59] <cuddykid> no
[17:59] <DanielRichman> hmm stripboard might be easier
[17:59] <DanielRichman> for just the avr & ntx2
[18:00] <cuddykid> ok, could i get one ordered online? or would that be expensive?
[18:00] <cuddykid> pcb that is
[18:00] <DanielRichman> £20+ I think but I'm not at all sure
[18:00] <cuddykid> hmm, will consider!
[18:01] <cuddykid> i'll 1st make on breadboard, then when its working will have a think
[18:01] <DanielRichman> OK. There won't be that many components involved unless you're putting tonnes of sensors on
[18:01] <cuddykid> no, i won't be putting many on as its 1st flight!
[18:01] <DanielRichman> also you're using the arduino right? or are you going to get a free standing avr ?
[18:02] <cuddykid> will it be ok to run just lassen off 3.3v from arduino?
[18:02] <cuddykid> yes, using arduino
[18:02] <cuddykid> the duemolvia or something like that!
[18:02] <DanielRichman> Duemilanove: DC Current for 3.3V Pin 50 mA
[18:03] <DanielRichman> The Lassen iQ GPS module requires +3.3 VDC ±0.3 VDC at 33 mA,
[18:03] <DanielRichman> typical excluding the antenna.
[18:03] hulettbh (~hulettbh@152.16.144.213) left irc: Ping timeout: 265 seconds
[18:03] <DanielRichman> the antenna will chew up ~20-30mA iirc itself
[18:03] <DanielRichman> so at best you're pushing your luck
[18:04] <cuddykid> hmm, ok, would it be best using a 5v pin and splitting voltage?
[18:04] <DanielRichman> cuddykid, when prototyping I recall that I ran the iQ from the 3v3 regulated output of the arduino, however on the actual flight I gave it a dedicated voltage regulator
[18:05] <DanielRichman> not with a voltage dividor cuddykid. Use one of these: http://www.rapidonline.com/Electronic-Components/Integrated-Circuits/Voltage-Regulators-LDO/800mA-Low-drop-out-voltage-regulators-LD1117/34991/kw/ld1117
[18:05] <DanielRichman> or similar. Be aware that the LD1117V33 that I just linked has a weird pinout; unlike every other LDO
[18:05] <cuddykid> ok, thanks
[18:06] <cuddykid> and you just hook that up to one of the 5V pins?
[18:07] <DanielRichman> and add a capacitor. http://alienproject.files.wordpress.com/2009/06/alien11.pdf first page on the left; I G O pins are labeled
[18:08] <DanielRichman> those are the values I've used. I'm not sure if they're correct, rjharrison for example uses different values I believe. And you can look at the arduino schematic to see what they've chosen (though it is a bit of a mess)
[18:09] <cuddykid> ok, thank you for your help! will do some research and breadboard a prototype!
[18:10] <DanielRichman> cuddykid, make sure you don't put the lassen iQ cable in backwards. You could fry both the iQ and the 3v3 reg with the short circuit
[18:10] <DanielRichman> if you're using the same one as we were it's poorly designed
[18:10] <DanielRichman> and the indentation on the case makes it look like it should go in the wrong way round
[18:10] <cuddykid> btw, danielrichman, what software did you use to produce those fantastic schematics?!
[18:10] <DanielRichman> cuddykid, eagle
[18:10] <DanielRichman> cadsoft.de
[18:11] <cuddykid> ok, will make sure with iQ
[18:11] <DanielRichman> cuddykid, eagle has a free version, on which the limits arn't too bad
[18:11] <cuddykid> by, put it in backwards, do you mean voltage wrong way round?

[21:44] <Hiena> The pure nitromethane on the dangerous chemical control list. What i could get is the 5-20% modell airplane fuel mix.
[21:44] <SpeedEvil> ah
[21:45] <Hiena> It's kind of oximoron, because the methanol and the nitromethane both on the list, which means, special licences to obtain them, but as modell fuel you could buy it without any question.

[22:03] <Hiena> On the meantime, i sent a mail to a local company, which makes oxigen generators. They wrote, the smallest generator would be approx. 5000 USD, the cyrocooler would be another 4500 USD.
[22:04] <Hiena> That out of budget.
[22:05] <SpeedEvil> just get the cryocooler, and distill it.

[22:13] <Hiena> The cyrocooler clogs from the dry-ice, and have to separate the nitrogen from the air.
[22:14] <Hiena> The oxygen genrator prepares 95% clean, dry oxygen.
[22:15] <Hiena> So no fuss with the water, the carbon-dioxide, and nitrogen.
[22:16] <Hiena> Also it comes with 5 year guarantee...
[22:20] <SpeedEvil> You could sell the O2! Be rich!
[22:22] <Hiena> Nah. Except, if i want to make a Oxygen bar.
[22:23] <SpeedEvil> I suggest you make Bars like the Aero - but full of oxygen.

[23:52] <fsphil> evening guys -- just on for a sec, real quicky question: do latex balloons have a shelf life?
[23:53] <fsphil> I'm planning two launches about two months apart, wondering if I should get both balloons at the same time

[23:58] <stilldavid> fsphil, I've read somewhere it's about 12 months
[23:59] <stilldavid> I let mine sit for about 14 and it was fine
[23:59] <stilldavid> but you should be fine :)
[23:59] <fsphil> ah that's loads of time
