content: This is very interesting. I am impressed by the duration and distance of this flight.I think that most of us on this forum want to more about your payload. I see an Arduino mini and I assume a GPS module. I like the use of thin enameled wire to reduce weight. How does it transmit its telemetry data, and who is receiving it?Maybe before flight S-10, some brilliant people here could help you reduce your nighttime power consumption so that you could send telemetry at least a few times to get better tracking over night.

content: HiThe Balloon is powered down now, but there is a possibility it could be transmitting as early as 03:30 UTC April 17th... when it powered down a while ago, it was just off the coast of Turkey and will possibly start transmitting telemetry after sunrise tomorrow in Iraq.The telemetry method is explained if you look on the index for S4 to the left of the map page.http://qrp-labs.com/ultimate3/ve3kcl-balloons/ve3kcl-s9.htmlBasically the transmitter sends out a regular 2 minute wspr transmission... (google it if you are not familiar with that term) then it sends a 2 minute wspr telemetry report. The telemetry is folded into the wspr format so it looks like a wspr report. This method will allow the decoding of up to 20 different channels or balloons at the same time. Telemetry could be any items you want, but in this case it is speed , more accurate maidenhead indicator, altitude, on-board temperature, battery voltage and a few bits for gps reception.It is all explained on the web page... there are some cool toys there too.Dave

I've followed several high altitude projects/launches but always go up, pop and fall down over the course of a few hours with a rather well predicted trajectory, never knew there were long range/duration experiments.What's the regulation around those? Can you jsut throw anything up as long as it's lighter than X? Feels kinda surprising you can have something wandering around uncoordinated right in the middle of where airliners fly.

content: HiAn update.... the Balloon just woke up in Turkmenistan and is heading for Uzbekistan.. yesterday there was a problem with the gps not handing off the data to the transmitter... so we used the wind plot to figure out the direction of the balloon.http://qrp-labs.com/ultimate3/ve3kcl-balloons/ve3kcl-s9.htmlTo answer your question about aviation worries.. the payload including antenna weighs less than a house sparrow and is wrapped in insulating foam.Some birds that weigh 20 times more, regularly fly over the Himalayas at 28000' and there is a vulture that can fly up to 37000 feet .. amazingWeather balloons have never caused an accident in aviation since they were first used, and over 400000 of these balloons carrying a transmitter of a 250gms weight (over 10 times heavier than a sparrow) are launched every year.Weather balloons expand to 16' sometimes but even in launch size, weather balloons are about 10 times bigger than the party balloons I launched.The antenna on the balloon is designed to fail at 3lbs pull in case it catches on anything. The solar cells are so fragile that they shatter on contact with any object... I have done this a few times by mistake.I cannot see any danger to commercial aviation that could be worse than a bird strike with a small sparrow. A Boeing that can weigh over 500000 pounds, would not be hurt even if it managed to find a balloon to hit... and that is probably one chance in a million.Dave

content: The balloon is a 36" party balloon that is usually inflated with helium and usually says" Happy Birthday" or " Too Old to Retire " or some other stuff. This type of balloon is called a Superpressure balloon, however the name is a bit misleading, as the "super pressure" in this balloon is only about 1/4 psi. What happens with a normal weather balloon, that is made of latex, is it goes up and expands up to 10 times it's volume till it bursts and then comes down by parachute. In a Superpressure balloon the envelope is less elastic and can't expand more than maybe 25%. It will rise till it is expanded, and cannot expand any more. At this point the density of the gas in the balloon becomes constant, at a certain altitude, and it will float along at this level ...depending on the weight of what it is lifting. In this case the float level is 10000 meters or 32800 feet.All explained on the pages of this sitehttp://qrp-labs.com/ultimate3/ve3kcl-balloons/ve3kcl-s9.html

The Balloon transmitter was sleeping, and it needs about 16 degrees of sun over the horizon to turn on the electronics.. .that happened this morning near White Sands in New Mexico at about 13:00 UTC. The transmitter transmits on 10.140265mhz and is received by automatic receivers all over the world and received spots are put in a database at Wsprnet.org where anyone in the world can access the information. The Ham call for the balloon is VE3KCL, and by typing that in, you will get the location and time of the received signals.There is a Ham in New Zealand who regularly received the signal from the balloon all over the world as signals in this particular frequency band, travel quite far at certain times.On coming home: One can never really trust a weather report , but if you look at the attachment, you could be hopeful that the balloon might come home to Ontario tomorrow... at which point, if it does, I will pop a cork on a bottle of champagne. And this would complete the balloon's rather drunken and lengthy circumnavigation of the globe.http://qrp-labs.com/ultimate3/ve3kcl-balloons/ve3kcl-s9.html

With the bureaucracy of today's world I would not be surprised if you need some kind of permit to do something like this and could get in trouble.I think it's pretty inevitable when sending something like this out that it will just vanish either due to human or natural cause, and it would definitly be cool to be able to know what caused it but would be a tough thing to do unless you can have 24/7 telemetry which would be hard to achieve. I think it's awesome that it worked as well as it did and kinda makes me want to try it. Would be neat to set one up that takes aerial pictures or something too.

content: What a great project!As for why it died, rather than it being shot down, what about failure of the balloon due to UV/sunlight degradation of the balloon skin? Or water penetration of the electronics. Something really simple like 'string broke.' Or icing up and sinking to the ground due to over-weight.Or, if the military did notice it and act, could well have been done using the new anti-missile laser systems.Suggestions for next time:- A power down/wakeup timer and enough battery capacity for at least a few fixes during the night.- A message on the outside "If found, please contact ..." (in a few different languages)And in the the probably too hard or too heavy category:- Tiny camera from a mobile phone, and ability to transmit images.- A small reserve battery, some means of detecting falling, low altitude or on ground, to allow a final burst giving last known position. Then a small RF pinger - very short burst every hour, for several days. Give the last known location and ping frequency to the geocaching community and see if they can find it.

Anything above 400feet or operated at night requires authorization from the country's aviation body. (Which they normally only grant to commercial operators, not hobbyists)In USA i think you need to be registered now, even to fly under 400feet.So make no mistake, an unmanned balloon traveling around the world is classed under the same rules as RC and totally illegal in pretty much any country it fly's over.

content: Quote from: Psi on May 01, 2016, 02:38:33 amUm, not really. There is a special category in the rules applying specifically to weather balloons and similar scientific stuff. Most of these high altitude balloon launches are done under that category, not RC modelling rules (which wouldn't apply for the many reasons you have outlined).Now whether or not the flight was legal under the weather balloon rules is another story - normally that needs a permission (not hard to obtain), some countries require that there needs to be some sort of a flight termination device onboard and the device is not permitted to fly across country borders. But those things differ between countries.For example for UK:https://ukhas.org.uk/guides:faq#do_i_need_to_get_permission_to_launch_a_weather_balloon_in_the_ukUS:http://community.balloonchallenge.org/t/regulations-overview-including-contacting-the-us-faa/676So considering this was a bunch of party balloons with a lightweight payload, it was in all likeliness completely legal to launch and fly if they got the FAA paperwork done in time. Better check the actual rules next time.

Apparently, he *did* have a GPS onboard, but unfortunately didn't know how to operate it. So he couldn't relay his position to the ground. A naval ship found his body two weeks later.He received a Darwin Award!A ton of other people have done it as well. In fact, it's actually an extreme sport now!As for Lawnchair Larry, a few years after his flight, he shot himself in an apparent suicide. At least he'll always live on in our hearts.

Hopefully it will be as successful or even better than S-9.As for the reason of the demise of S-9, IMHO it's likely it just failed, given the history of the previous flights. Besides, if it can fly over war zones and be discussed openly on the internet, it seems likely to me that those who might have an interest might be aware of it but are just not bothered by a DIY device that does nothing more than report its position.

I think it's incredible it lasted as long as it did. I'd still be a bit worried of getting in trouble if they do intercept it though, you know how ridiculous things are now days, seems you can't do anything fun anymore. Just look at all the rules for drones and the fines for not obeying are ridiculous. But it would be kinda hard to track where it came from so I would not worry. I doubt they'd pursue it for very long unless it actually brought down a plane or something which I doubt is even possible. Could be neat to make a throw away email address (use Tor) and have instructions on the payload to send details if found though. If another civilian finds it they might do just that and you'd get to know if it fell out of the sky, and where.Could be neat to mount a camera that takes aerial pictures once in a while too, what kind of bandwidth does the radio have? I imagine it's not very high or reliable enough though.

content: Hi allI work with Dave VE3KCL on the firmware and software side of these balloon flights. I run QRP Labshttp://qrp-labs.comand the balloon flights essentially use my Ultimate3S QRSS/WSPR TX kit qrp-labs.com/ultimate3/u3s (U3S) but with 1) Arduino nano board which is smaller, and 2) Special firmware which transmits the telemetry over WSPR. Note that this is NOT an Arduino sketch - it is just the Ultimate3S code special version, programmed onto an Arduino Nano board, which uses the same processor (ATmega328).I read all the forum posts and just a few comments briefly...Firstly I believe S-9 was brought down by bad weather. Even at 10,000m altitude, there is some weather which reaches up that high. A leak would result in a slower descent. Although the flight time was 18 days, the balloon should be able to stay up much longer than that.Tracking over the oceans was mentioned a few times. The balloon transmitter has a power output of about 16mW on 10.14MHz. The signal encoding is very low data rate, which results in a very narrow bandwidth, approx 6Hz. This narrow bandwidth means a very high signal-to-noise ratio is achieved in the system, and this makes it possible to receive at very long distances despite the very low power. A station in New Zealand copied some of the transmissions from Europe for example, by long path - this is over 20,000km. That's several oceans and continents!Regarding S-10, it has a problem with its GPS. This doesn't just mean that we don't know where it is! In the U3S the GPS is also used for frequency calibration (to correct temperature drift) and for keeping the real time clock accurate. WSPR is a mode which is synchronised to the 2nd second of even minutes past the hour. There are a few seconds of tolerance, but if the real time clock drifts outside this then there is no decoding.There were two reports from S-10 today but only one of the WSPR transmissions (telemetry) so we do not have the position. Those reports could have been random false decodes of the noise, but their timing was correct for S-10... which is unlikely by chance... so who knows. S-10 might still be doing Ok, just not very good at telling us about it!Another related topic - Bob ZL1RS is the station I mentioned in New Zealand who received the balloon flights from the other side of the world. He now has an ocean buoy in the South Pacific, which also uses a similar system. He is also using a Ultimate 3S transmitter. A much more leisurely 2 knots speed in the ocean currents ;-) More details herehttp://www.qsl.net/zl1rs/oceanfloater.htmlHanshttp://qrp-labs.comhttp://hanssummers.com

content: Looks like the balloons finally got someone's attention. The web site is hacked and now my anti-virus rates it too dangerous to visit.

content: You sure about that? Chrome doesn't seem to think anything is off about it. Do you have some kind of plugin anti-malware? The heuristics engine has probably just gone mad.

S-9 was the best until NORAD shot it down with their ground-to-air laser system (works only on party balloons - but still cost $100 billion).FYI My Firefox is ok also

content: Wow!I was thinking of doing something like that, but had no idea about WSPR.The idea was to either put a cellphone modem or the Iridium modem on the balloon.But the former probably won't work far from cities and out of the country, so there will be some spotty tracking and then silence.While the latter is obscenely expensive for a disposable job.So, this basically rely on the network of tracking stations that can pick up the standard 50 bit packet?Is there any way to send back more data?How common are the conditions that allow stunts like hearing a balloon over Europe from New Zealand?If that can be done more or less all night, then that should be enough for a very compressed picture or something of this scale.

content: I don't think a cell phone will work at that height. I once made a hot air balloon flight, only a couple of hundred meters in the air over flat land (not even hills). When I tried to phone up people who I was flying over to tell them to look up in the air, it was almost impossible to get a signal from the cellular phone network (GSM).

I have had no problems previously when accessing ve3kcl's website via IE.

content: IE has some hooks deep into the system, half the features probably get blocked by A/V on the basis that it is an integrated backdoor engine.

S-11 is the current flight which can be found on the left side of the screen. Scroll down to see the flight path of S-9. It almost made it around the world.http://qrp-labs.com/ultimate3/ve3kcl-balloons/ve3kcl-s9.htmlpics :http://qrp-labs.com/ultimate3/ve3kcl-balloons/ve3kcl-s9.html#photosCircuit boards included here
