- High tech falling out of the sky? Is this true? Yes, 3000 times each day around the world. And it can be a lot of fun to hunt this “fall-out.” With a LoRa module, a Raspberry Pi, and an RTL-SDR dongle. Come with me on a drive through the night. And learn how you can experience such adventures, too. Maybe with your kids?

Meeting strangers 101: Nowhere at night, shout "Hello guy with the swiss accent" and everything will be alright.
Good idea ;-)
Personally I would be armed with a Toblerone, just in case!
On a serious note, do these balloons ever come into contact with aircraft?
@@r1273m Not really, the launches are both coordinated with air traffic control and the balloons cross the range of altitudes where planes fly fairly quickly so the chances of a plane hitting one of these are extremely low.
@@r1273m He is armed with his Swiss Army Knife!
I'd poo violently if I ran into someone in the dark wilderness wielding a fully loading Toblerone
Thank you Andreas for this hack of Meteo Balloon, this is very interresting and I will make my own receiver. I'm the President of the association Swiss-Strato in Lausanne and we send Balloon for school or for experimental purpose. I develop my own LoRa tracking baord. The last flight was this week and we try to measure radioactivity with a simple geiger counter. If one day you want to do you own balloon launch, fell free to contact us. We are a small team with many experiences for predicting and tracking. We will be very happy to share with you and your community the launch and the hunt.
Maybe you send me a message on Twitter or Facebook to exchange our address?

O
You really made me laugh! I did not expect that you will go out in the woods at night to chase the fallen balloons! I really admire your work! You really inspire me!
Also in my age some people are still alive and want to do something ;-)
3 months ago I saw this video, I thought that's pretty neat and ordered the equipment, within 2 weeks of then it arrived, I programmed/flashed it and awaited a day where one came close (the UK is in lockdown and we can't travel far). This morning at 5am when I woke up I had an email saying one landed within 5KM so I rushed to get ready and go, within 30 minutes I found it in a field, had the land owners permission to get it and was back in my car on the way home. It is my first catch and I am super happy with myself - thanks for making the video Andreas.
Very good! Since December the balloons here fly direction Italy. So no chances for me to get one inside the 5km range like you!
@@AndreasSpiess Yeah I was definitely very lucky, usually they're at least 50KM away. Thanks for making such an informative and helpful video!
I really enjoyed this video. I remember finding a weather balloon in the early 70's while doing my 5:00AM morning newspaper delivery in Texas. It was so exciting and I will never forgot. Of course, I took it apart to inspect. In those days, a cloth bag with return postal instructions was included. I bagged up and returned the remains after a few days.
I am not sure if this was their intention ;-) But you learned something!
Always a pleasure to watch your videos! As a young swiss engineer, it give me a lot of ideas to try in my workshop!
And this one even in the nature ;-)
Found my first radiosonde today. Thanks for your instructions.
Congratulations!
14 years ago I used to chase balloons that were carrying repeaters for a telecommunication company. It took me all over New Mexico and Texas. Those are good times. The company gave me their locations and I would give them back and get a bounty for each balloon I captured. The company was called Space Data.
This is like in the very old days when the Sheriff hunted for some bad guys! At least this is how it is shown in the films.
I di not know they had repeaters flying around. Must have been big balloons.
@@AndreasSpiess The balloons were quite large but I don't remember the exact size. The payload was 1 foot cube and had ballast as well as a parachute. The operational altitude was 60,000 feet and above. I don't know the frequency or protocol used (I wasn't interested in radio at the time) but looking back. It seemed to be 70cm or shorter wavelength. Their tracking system used GPS for location and other airborne repeaters to send the location back to a ground station. The mission was to track oil production and freight movement in areas with no other telecommunication options.
Many thanks for your inspirational videos - particularly this one. After two previous unsuccessful attempts I finally recovered one. Whether climbing through hedges and wading across swollen streams is a suitable hobby for a retired gentleman only time will tell. My wife says not, but of course ...I have now tasted blood!
Here you have to listen to your inner voice, not to your wife ;-)
You are the guy I wish I had for a neighbor. What great fun.
Thank you!
You're a mind-reader!. Just arrived a RTL-SDR dongle, and found an old Raspi at home. Thank you Mr. Spiess. Let the chase begin...
Hopefully you will be successful!
Very entertaining video, this search for weather balloons is high tech geocaching.
That is what I thought, too!
Very nice Video Andreas. When you shut off the sonde asap then you have very good AA batteries for your TV remote controller right from the near space....what is really cool.
And they work even in winter with an open window ;-)
Thank you Andreas for again digging a really interesting topic "around sensors and microcontrollers". The more I dive into the things you spend your time on, the more I consider to finally get this amateur radio license thing done.
I just switched my new IC-7300 HF Transceiver on. Listening to a CW contest. Interesting. And no more very complicated to get the license.
But for the balloon hunt you do not need to have a license.
@@AndreasSpiess I am aware of that. But you tend to connect me to that topic in a more general way. And as I am a Nachrichtentechnik-Ingenieur, it's perhaps kind of mandatory anyways ;-).
@@AndreasSpiess Why do you need a license in this case? You are just receiving signals, not sending anything, right?
Hi Andreas. Thanks for infecting me with another obsession!! I've hunted down several sondes since watching this great vid. However I've been pulling my hair out as I couldn't get more than a few metres range with my mysondy go. I just facepalmed when I realised why. I ordered a 433 mhz ttgo from Amazon months ago and I've just realised it says 915mhz on the back!! No wonder it's barely working !!
Indeed, a good discovery! The filters on this board are made to block frequencies other than 900MHz...
@@AndreasSpiess The filters are doing a pretty good job - I had to be close enough to see the sonde before it would pick up the signal. I spend so many hours trying to figure out the problem and it's such a noob error - So frustrating. I even bought a VNA to tune my antenna (Thanks to Vid #191 th-cam.com/video/ZpKoLvqOWyc/w-d-xo.html). Oh well it should work really well when I have the correct device !!
Have had my first successful retrieval last night!! The balloon burst at 36000m and I was lucky enough to watch it hit the ground! The nice thing about my latitude and time zone is I get 2 launches during full sun (for half the year). Thanks again for the quality introduction to a fun hobby. My kids make great navigators😉
Great that you also involve your kids!
Update -- so excited to have found our first balloon today! Only about 5 minutes hunting in an open field. I've ordered up my TTGO to get ready for the trickier ones. Excellent - many thanks Andreas!
Gla you enjoyed the hunt. Please update the database if not already done.
I love explaining your videos to my 7 year old daughter. About the planets atmosphere and his different layers, air pressure and more in relation to weather balloons. Thanks
And maybe you hunt for a balloon with her...
Especial felicitación para Luciana Magnoli. Tus traducciones, además de ser correctas, tienen un incalculable valor. Muchísimas gracias Magnolia!
And many thanks for other marvelous video Andreas! You are BIG!

Thank you. I sent her your comment.
So far, found 2 radiosondes. Third is there somewhere in the forest, but all searches were futile. Great video anyway! Thanks!
Cool! If they stopped transmitting, they are hard to find in a forest…
@@AndreasSpiess Yes, that is true. I still have hope to find it. My friend actually heard on his walkie radiosonde, but at that day unable to go further into forest. Now, I am still trying to find it. Other two radiosondes are no problem to find, got there and by using LFA antenna, found it relatively quickly.
What A great fun video these slightly different videos Are the ones I like best. Thanks for all the work and sleepless nights . Simon
Glad you like them! You probably saw that I also liked the topic a lot.
Of course we're going to call out... it's nighttime, in a forest, and you've got a Swiss Army Knife! 😁
And a big one!
@@AndreasSpiess If I call out and a guy with a Swiss accent answers, I'm running the other direction! I'm in Texas, USA. :)
Thanks to this guide, i will make my own tracker, thank you. There is a realistic change that we meet while hunting. I am from Maisprach :-)
Very good. Maybe we meet one day...
Sehr schöne Idee und wieder unglaublich lustig und unterhaltsam. Danke, Typ mit dem schweizer Akzent :)
Bitte, gern geschehen!
Wow, you have inspired me to try to find a radiosonde or three! Thanks!
Go for it! It is great fun.
Great project !!!! Thanks for that dear Andreas !!! Stay safe.
Thanks, you too!
Wow, what a great fun project - thanks for sharing with us.
You are welcome!
Your videos are so inspirational!!! Can't wait to reuse these as party balloons!
You hardly find intact ones. Most explode :-(
Very interesting, i will look into that topic. I learn many things from your videos. Thanks Andreas.
My pleasure!
9:13 "I found a small hole in the fence", proceeds to cut the hole with pliers... Nice video Andreas, you are the inspiration for me to start a weather balloon hunt. Cheers from Greece.
Go for it if balloons land in your vicinity!
Always good entertainment in bed on Sunday morning. Puts a smile on wife‘s face :-) She didn‘t hear you for a while but today she did. She thinks you improved your English!
Say her hello and thank you for the compliment!
What a cool episode! Thanks to the Radiosondy website I just found out that balloons are taking off daily just a few kilometers from my home in the north of Stuttgart, Germany.
So good luck!
It is more din when they land close to your home.
Hi from New Zealand. I actually release RS41 sondes from Invercargill. The connector on the bottom of the board is not just for programming. Its mainly to connect to Ozone sensors for doing Ozone soundings. Before releasing the sondes, we sit them on a ground check device which powers up the sonde and sets its frequency, as well as checking all the sensors. This is all done wirelessly. The old RS91 sondes needed plugged in to start and set, but not these ones. Cheers!
Thank you for the update. I knew about the ozone Sonde connection (I already found a few of them). But I did not know that it is wirelessly programmed!
I enjoyed this video! Thank you for this great information. I tasted blood, too! :D
Good luck!
Thank you for this very interesting video, now I've added this to my bucket list as well
Cool!
Sehr cool, mein Jagdinstinkt ist geweckt :-) Ich habe auf dem APRS Netzwerk schon ab und zu Meldungen auf 144.8 empfangen. 73 Tom HB3YSB
Das waren vermutlich private Ballone. Es fliegen ja einige Selbstbauprojekte... 73 de HB9BLA
Andreas, vielen Dank für deinen interessanten Beitrag.
Jetzt werde ich wieder viel Geld ausgeben😀 Aber gerne.
Viel Vergnügen dabei!
So interesting Andreas.
Have wondered about these devices.
For storm analysis they fly over the cloud and chuck a bunch of dropsondes out of the plane.
These then parachute through the storm and provide data for storm analysis.
Radiosondes are still relied on as the best means to obtain atmospheric data, it is a crucial part of forecasts for aviation.
Thanks for a lovely video.
Kind regards,
Duncan, South Africa
I do not know if they have such storm sondes here. But also the balloons can go quite fast. The max speed I saw without storm was 133km/h
@@AndreasSpiess I see NASA sends drones up to drop these Sondes into the atmosphere. That's how they get the info about wind and direction on the day a rocket is being launched.
Wonderful video I am going to build my ground station today. Thank you for a lovely video
Good idea. Enjoy!
Great video, I love it when I find out about something I didn't know "was a thing". I'm not sure if I would try this in the US, I may get shot.
I do not know. Two US sites are also covered on radiosondy
Die Luftballons in der Region Bodensee gehören mir! :P
Du musst einfach früher aufstehen als die andern ;-)
Your chase and hunt at night is thrilling... Cheers! Please stay safe. Best wishes for many more adventures!
Indeed, I still remember this nicht. Now I am already at #14 (balloons found)...
Very interesting work there, Andreas.
Might just look into this projekt myself.....,
Greetz von Australia. :)
It is a lot of fun. Recently I found three additional balloons. The winds were blowing in our direction…
Great video as always.
Highly informative and highly entertaining!
Thank you!
Muy interesante el proyecto.Gracias por compartir
You are welcome!
This was a very fun video, best regards from Perú
Glad you enjoyed it! In the meantime I found another one :-)
Thanks for the inspiration! I retrieved my first radiosonde a few days ago. Great fun!
Congratulations!
Interesting, Good Luck.
Thank you!
Fun project! Thanks!
Glad you like it!
Good stuff! I used to listen to radiosondes in the southwest UK in the 1970s, when they were on 27 MHz just above the (illegal) CB band. They were analogue, of course, and I think they may even still have been using thermionic valves. The various sensors generated voltages, and a rotating motorised cam coupled them in sequence to an audio VCO which AM'd the transmitter - so there was a regular twelve note musical phrase with a regular rhythm, with the different notes drifting at different rates as the various weather parameters changed. Late at night on an otherwise dead band it was very eerie hearing this machine music drift in and out of the static as the balloon moved away. I'd love to find a recording of this, I can hear the tones so clearly in my memory.
Maybe you find somebody who still has one of those sondes somewhere in a museum...
@@AndreasSpiess I've been looking for one for years for my colleciton of weird wireless. I even asked the UK Met Office, but no - and they were used in India until quite recently, but still no joy. I shall find one!
Whaha As a nerd not interested in latex but in in the radiosonde. will remember that one
Important learning ;-)
Waw, this is a really cool project. I'll look into to building a device myself ! Sounds interesting ! As usual...
It is not too difficult. And a lot of fun!
Very interesting hobby, must say I am considering to join. Thanks Andreas for another very interesting video!
You will love it, I am sure
Just imagining ringing the good lady and having to admit I've found the ballon but lost the car!!!! Maybe I need to track the car???
Visions of folk in the U.K. being fined £60 for meeting in fields during the night during the current lock down.
Fascinating idea though - thanks for the video.

Talk about fresh idee-ers in sensors and microcontrollers. This is the best! Thank you Andreas.

As we learnt from the James Bond film.
Just remember to leave some part of you uncovered and you'll be fine.
I was like “what? Did he say that..? Rewind... Rewind”
That was fun. I was in the ham radio club when in college 50+ years ago. I remember doing some hidden transmitter hunts with portable receivers and little yagi antennas. You are doing a high tech version of the same thing. However it was easier for us flat landers in the USA and we did not put the transmitters high in trees. i enjoy your channel. Good work, well organized, well presented.
Technology changed a little over the last 50 years ;-) And I enjoy the today's possibilities!
Excellent 👏👏👏
Thank you very much
I'm all for weather balloon hunters the world over yelling "hello guy with the swiss accent" as a pass phrase. :)
Good idea! I like it.
3000 a day! - what a lot of pollution :( So I'm please Andreas that you are inspiring others to hunt them down :) An interesting video - thank you.
You are welcome!
Impressive build, and simple!
Thanks for sharing :-)
Glad you like it!
What does your wife says when you run, in the night, telling her you are going to persue balloons will return with some latex? 🤣🤣🤣
That is another story ;-)
100% I will try this out!
All the best from Rapperswil and thanks a lot for another great video
Good luck!
Now the only thing left to do is get a balloon much higher than 40 km and find some curvature...
I guess we have enough distance to not meet at night ;-)
And i probably would shout something bulgarian here.
Good luck with the next ones ;-)
You are right. The reach seems to be in the 100km. And it seems there is only one receiving station in Bugaria...
Nice Volvo 😉

Growing up in Arizona as a avid hunter and motorcycle rider I happened onto two of the old school sounds. They used battery piles soaked in salt water to power them.
Now they use Lithium batteries I do not know which one is better...
@@AndreasSpiess I think they used what was cheap back then. Disposable. They never expected to get them back.
What a great hobby!
I agree!
brilliant video very interesting. given me a nice little project to do many thanks
It is a lot of fun for the money...
Very entertaining episode!
Thank you!
This is better than treasure hunting
I agree!
Friend and I caught our first sonde (RS92) almost 6 years ago. Got very lucky because at that time I did not know you'd have to fox hunt for the signal. Literally retrieved hundreds of radiosondes ever since. However, with these simple finding devices it has become very easy to chase sondes and there are now too many hunters in my area. It's simply not worth bothering about, unless the sonde falls on my doorstep. I miss the days when friend and I were crawling around in the dark, with a Yagi TV antenna in one hand, and a laptop in the other.
I can imagine that this was more complicated and needed more skills back then.
Thank you. Ordered the TTGo boards. Plan to try it out. You have a drink waiting for you in SG.
Only after you found one ;-)
Das ist so verrückt und so genial 😁👍
Danke!
Absolutely fascinating
Thank you!
Well, I was just researching, earlier this week, about doing this, and now look what we have here!
The solution. Proven.
@@AndreasSpiess Exactly! I really appreciate your channel, BTW.
" geday Mate , this one's mine ;^)". Another inspiring video Andreas , i love a 'fox hunt'. thanx for the idea.
Good luck finding one or more of them!
@@AndreasSpiess I am surprised there isn't a requirement to return the payloads.
Loved the video. Very nicely done!!!!!
Thank you!
Loving this topic/ it's like Hi tech geocaching. Already have the kit from previous projects to start hunting. Would be a good addition to the firmware to have a frequency scan feature. within the app for the TTGO. as at the moment i have to open SQ6KXY web page to check what is local to me and tune the TTGO to the frequency via the companion app. Would be great to have the TTGO running in frequency scan mode and once it locks on to a Sonde. pulses the led on GPIO25. of which i would attach a an active sounder to alert me of a passing weather balloon. So i could boot up a PC to find it's expected trajectory. Lazy i know. But a balloon passing near is a rare event. This is a big ask as the firmware is a BIN file and is not open source.
I look at the prediction for the next week to decide what to do. And as soon as the balloon is started you know its frequency. Scanning would probably increase the complexity. For example, if you receive more then one signal.

Hi, last Fall your video inspired me to order a LoRa Board and build the MySondyGO. Two days ago, I successfully recovered my first RS41. During the preparations I found out that here in the "Dreiländereck" F-CH-D we do not have ballons coming in so often. And those which are coming have travelled a long way in stormy weather and predictions are unreliable.
Congratulations! You have to be patient. The winds will be better one time. You can have a look at the history of balloons from Payerne ( radiosondy.info/maps/web_map.php?kml=1&search_limit=10000&startplace=Payerne%20(CH) ).
very good
Thank you!
Really funny video, my raspi runs since Dezember and i also found my first radiosonde. Looking out for more, but bad location on west and east wind. But maybe ....
Congratulations! I also do not live in a good spot :-(
cool
:-)
for hunting, all you need are AIM-9Xs
Ou balloons are much smaller. So maybe a sidewinder would not hit ;-)
