FS#1 – A word from the accounting department – The cost of FS#1

One of the goals of the Flying Squirrel mission was to keep the project “affordable” so that a STEM education program or individual can afford to conduct similar missions. The arbitrary chosen goal was to keep the cost per flight under $50.00 USD. The spreadsheet below shows what the FS#1 flight costs were. Spoiler alert, […]

FS7 – The Flying Squirrel #1 Flight controller software

The FS#1 flight controller is designed to measure basic weather information (Barometric Altitude, Air Pressure and Temperature) and relay that information periodically to the ground via radio telemetry using the FSQ protocol. Additionally, the flight controller conserves battery power by turning off the radio and weather sensor between transmissions.     In a nutshell the […]

Mission Launch Anouncement – Flying Squirrel #1

Meet our intrepid explorer Flying Squirrel One. This very brave explorer will be the first Squirrel Engineering project to be launched in to the upper atmosphere lofted by nothing more than a 36 inch Helium filled party balloon. During the flight, our explorer will dutifully report temperature, air pressure and altitude back to mission control […]

Flying Squirrels #6 – FS#1 Mission and goals, What’s the point?

The Mission Before I can describe the flight software I need to make clear what the specific mission goals of Flying Squirrel #1 (FS#1) are. The software design is based upon these goals and an understanding of the goals will make the software easier to understand. In a nutshell the goal of FS#1 is to […]

Flying Squirrels #5 – The Flight controller

The flight controller of Flying Squirrel #1 is the brains of the flight. The controller will measure the environment around the balloon, format the data into a Telemetry message and transmit the telemetry signal back to the ground using the chosen protocol (FSQ) for the flight.  The flight controller will also manage the power to […]

Flying Squirrels #3 – Can you hear me now? – Building a transmitter

Now that I have a list of protocols and a general plan to transmit telemetry on the 20 meter Ham bands, how do I get “on the air”?  This post will describe the transmitter hardware for the telemetry system. Generating Radio Frequency – There is a board for that. After a lot of searching an […]
