May 27th 2024 Northern Illinois Bottlecap Balloon Brigade update

We started the Northern Illinois Bottlecap Balloon Brigade on June 9th 2021

Without any previous knowledge of this project. We spent the summer researching, and began launching Pico Balloons, 3 months later.

We will be celebrating our 3rd Anniversary in a couple of weeks on June 9th 2024.  In our 3 years we launched over 35 Pico balloons.

In our early months we were launching on a regular basis, sometimes two or three times a month.  With some successes along the way.   We had our 1st long flight in December of 2021, of Pico Balloon KD9ORR that flew 19 days, crossing the International Date Line twice in the same day.  Once going east, dropping out of the Jetstream and then going back west and spending 8 days around the Marshall Islands.  It was fun watching and reporting on that balloon.  We started our website during the flight of KD9ORR.  Click here to follow our 8th launch of Pico Balloon KD9ORR

We had three flights in 2022 that made multiple circumnavigations. Pico Balloon AA6DY launched in September, for 83 days of flight and three times around the world, Pico Balloon K9YO launched in October for 123 days of flight and seven times around the world and Pico Balloon KD9UQB launched from Antarctica in November for 100 days of flight and seven times around the world.  

Our Antarctica launch was conducted by Todd McKinney, KN4TPG a student with the University of Alabama in Huntsville.  Our other partner on this launch was Tom Medlin, W5KUB who we continue to consult with on our launches.

We launched two Pico Balloons on April 13th 2024 for Calvin Knowles KD9WNU and his Mom Janet Knowles KD9WVO.  Below is our group who participated in this launch. The slideshow of our launch is on our home page https://nibbb.org/

Both balloons stayed pretty close to each other for their flight, but we lost Calvin’s balloon over Ukraine after 5 days of flight.  We believe it was a weather that brought the balloon down.  Calvin likes to tell his friends that it was shot down.  

Janet’s Balloon KD9WVO-11 has been doing very well, now over 43 days of flight and preparing for its 3rd circumnavigation very soon.

Since our last launch on April 13th 2024, we also lost communication with Pico Balloon NE9JJ-2 that was carrying a weather sensor built by Todd McKinney, KN4TPG with the University of Alabama in Huntsville.  NE9JJ transmitted for 44 days, and 4 times around the world gathering weather data that Todd found very useful.  NE9JJ is Jim Janiak who’s callsign was KD9UQB for the Antarctica launch and some others.

Although I haven’t written here in over a month, you can follow our balloons in flight which are updated daily at our Locate and Track page at this link https://nibbb.org/links-to-locate-and-track/ 

Our website header shows our balloons sharing the skies with other Pico Balloons flying around the world. It’s a big world and a small part of the hobby of Amateur Radio.  

Tracking worldwide Pico Balloons is provided by Sondehub which is the 1st link on our Locate and Track page.

All the pictures from our last launch and group projects have been moved to our home page https://nibbb.org/  Our home page also has group pictures of our NIBBB members through the years, and slideshows of our launches and build projects that I hope you’ll visit and share with others.

We have close to 190 followers here at the NIBBB that receive emails when posts are published.  Our most recent followers are from Australia, the United Kingdom and Germany. 

We look to our worldwide group of Amateur Radio operators, to help track our balloons, receiving our packets and report the data.  If it weren’t for them, we wouldn’t know where we were, wouldn’t receive important data of our location, and altitude, additional data such as temperature, humidity and pressure at altitude, and how our trackers are behaving during the flight. 

Our followers can point their antennas where we’re projected to be, by going to our Locate and Track page for our reported location and the forward trajectory NOAA Hysplit Model, as shown below for Pico Balloon KD9WVO. NOAA provides us with an 84 hour projected trajectory that we update daily.

I’d like to also thank our members of the NIBBB for their dedication, and time.  

We’re looking forward to our launches in June for Gordie Mulley KD9TVR and Kelsi Mulley KE9LSI, who’ve been waiting a long time for their launch.  Mikaela Streicher, KD9VIW will be launching sometime after June.

Calvin Knowles KD9WNU and Gordie Mulley KD9TVR are finishing the 7th grade in a week or two.  Kelsi Mulley KE9LSI just completed her junior year in high school.  Mikaela Streicher KD9VIW just finished her freshman year in college. Elizabeth Ziemer KD9ORR with our original group just finished her junior year in college.  Henry Fiely KD9SRZ from our original group is finishing his freshman year in high school and Noah Berg, KD9RDT from our original group is finishing his sophomore year in high school.  Congratulations to our younger members of the NIBBB.

We’ll be sharing information very soon on our new tracker which we hope to start launching in July. For now, the group is working on a development board testing the chips and software.

Thank you to everyone around the world who have shared our project with us.

July 12th 2023  Prep for Launch

Last Saturday, July 8th 2023, our three youngest Generals, Gordie Mulley; KD9TVR, Kelsi Mulley; KE9LSI, and Mikaela Streicher; KD9VIW met with Ken Daniel; K9YO and learned how to put the Pico Balloon package together. The package consists of a 7 cell solar panel, Pico tracker, antennas, monofilament line and balloon. Doug Mulley; KD9TPM was there to assist with the build.

The group found that many of the solar panels that were built on September 10th 2022 had cracked cells, thanks to Jim Janiak KD9UQB, everyone in the group knows how to fix those.

Below are images from our September 10th 2022 Solar Panel Build Session

Stretching the balloon

I met with Ken a week before his build session where he was in the process of stretching the 4th SAG Balloon. After the Pico Tracker and Solar Panel are built, the antennas are soldered to the tracker and the balloons are stretched prior to filling with either Helium or Hydrogen. The stretching of the balloon gets all the wrinkles out allowing for the balloon to reach its maximum altitude for the duration of the flight. Depending on the weight of the total package, we can expect an altitude of between 40,000 and 50,000 feet. The heavier Low Sun Angle – High Power Solar Array for winter flights would get around 40,000 feet. The Standard Solar Array shown above would get closer to 50,000 feet.

We have 10 Yokohama balloons and 6 SAG balloons ready for stretching. The SAG Balloon and Yokohama balloon are both 32” rounds that can be stretched to a 100 inch circumference.  Ken wrote a program that slowly stretches the balloon over a 10 hour period using an aquarium pump and an arduino

Ken Daniel, K9YO has created a website “Everything About Flying a Pico Balloon” With a video on stretching and filling a balloon.

While Gordie, Kelsi and Mikaela are finishing their builds, they’ll be teaching the rest of us on how to put the package together.   

Stay tuned for the launch of Pico Balloons KD9TVR, KE9LSI and KD9VIW
