A High Altitude Balloon Project To Generate STEM Interest And Learning

Several members of our club have been working on a High Altitude Balloon Project to promote STEM interest and learning by young people. Our project team currently includes the following folks:

Other interested club members are welcome to join us.

We want to provide a STEM learning opportunity and project to be planned and executed by young people ages 10 – 16. We are actively seeking engagement and support from local schools, Scout Troops and other youth organizations to help us with this project.

Our goals for the project include:

  • Building and launching a high altitude balloon carrying Amateur Radio to near space and back
  • Enabling young people to plan and execute the project with help and guidance from members of the Nashua Area Radio Club and supporting adults from organizations that wish to assist us
  • Helping young people gain STEM-based experience and learnings by handling all phases of the project including:
    • Planning the flight, the balloon, and its payload
    • Building the balloon and testing it on the ground
    • Launching, tracking and recovering the balloon’s payload
    • Analysis of the flight data and the creation of a presentation to be delivered to fellow students and other interested groups

We plan to introduce new technology, experiments, and flight elements and develop team member skills and expertise across multiple launches. Later phases of the project are expected to include design and construction of additional payload electronics, high altitude/longer duration flights, and additional on-board atmospheric science experiments.

Our goals for the initial flight mission of this project will include:

  • Building a helium filled balloon which carries a payload of < 4 lbs. to altitudes in excess of 90,000 ft (27,400 m)
    • Parachute controls decent rate after balloon bursts
  • Capturing a video of flight using on-board GoPro video camera(s)
  • Flying an on-board APRS transmitter allows tracking from the ground via Amateur 2m APRS and aprs.fi
    • Flight computer plus APRS provides altitude, position and temperature data throughout the flight
    • Anyone with a device that has internet access and a web browser will be able to track the flight
  • Augmenting the APRS system with commercial satellite tracker to assure successful recovery of our payload by the project team

The balloon is filled with enough Helium to carry its payload to a target altitude in excess of 90,000 ft and then burst. A parachute will deploy to control the rate at which the payload descends and will ensure a controlled safe and soft landing.

The payload will be built around a light-weight platform which will carry a Video Camera, a Flight Computer/APRS Transmitter, and a Commercial Satellite Tracker. The camera will capture a video of the flight and the flight computer will record altitude, temperature and position data and relay this information to the ground via APRS on 2m. A commercial satellite tracker would be included to ensure we could locate the payload once it is back on the ground.

High Altitude Balloon Flight Planning

A key part of the project will involve planning the target altitude and flight path for our balloon. There are some good resources available to help us do this. Check out the Balloon Performance Calculator here. Tools also exist to estimate a balloon’s flight path and track based on Jetstream and other flight parameters.

High Altitude Balloon Tracking

Once we launch our balloon, we can track it in flight via the Amateur Radio APRS network on 2m. The payload will transmit position and other information via APRS that will be received by the many APRS receiver stations that have been built by Amateur Radio Operators. The data from our balloon will be relayed to aprs.fi in real-time and will be able to be displayed on any device with internet access and a web browser.

High Altitude Balloon Flight Data Analysis

Once we recover our balloon payload, we will guide our young team members in analyzing the data from the flight to help them to learn about atmospheric conditions and to prepare to share the results along with the video captured with classmates and other interested groups. You can get an idea of the video that we can expect below.

 

We are working to raise the necessary funds to support our project.  We are counting on the generosity of our members and friends to help us.  Please consider making a donation here.

Show Your Love for Amateur Radio on Feb. 14

February 14, 2017, now represents two important days: Valentine’s and Nashua ARC’s Feb Tech Night! Nothing else says love like telling that special someone — you want to solder some electronics 🙂

Back by popular demand (and good reviews from others) is our kit building night. Everyone had a blast on Election Night building the Pixie kits, and on V-day, we are going to work on a DIY oscilloscope known as the DSO138. (It is mere coincidence FYI that our kit building nights have fallen on holidays, of sorts).

The nice thing about this kit, of course, is being able to visualize some of the basic waveforms used in electronics. The kit does come with a square-wave test signal, but we will also have a signal generator present to visualize more complicated waveform.

Building this kit is an excellent opportunity to hone those soldering skills, brush up on electronics theory, and add another fun toy to your growing (or perhaps overflowing) collection. The price point is definitely fair for an oscilloscope and may help you figure out if you’ll want a more sophisticated one down the road.

We had about 15 people last time, so I think this time, it’d be great to expand that number to 20 (or more)! Buy a kit here, and join us in February! Looking forward to seeing you.

N1FD Multi-Op Entry in the Rookie Roundup CW

The N1FD Contest Team operated in the final Rookie Roundup of the year – the ARRL Rookie Roundup CW.  Jamey, KC1ENX and Abby KC1FFX operated as a Multi-Op team using the N1FD callsign at the QTH of AB1OC and AB1QB.

The CW contest proved to be a great way to improve the CW skills of the rookies as well as the Elmers!  It was the perfect follow-on to the Morse Code Class held earlier this year.

Abby and Jamey made a total of 21 QSOs in the contest, including one with another rookie from Alberta, Canada.  Most of the activity was on the 20m band with a few contacts on 40m.

We all had a great time in the contest and are looking forward to working another CW contest soon.

We’re also looking forward to the next Rookie Roundup, the SSB contest which will be on April 17.  We invite all of the new hams in the club to join us for the SSB version of the contest.
