Our eager squirrel was anxious to try out its new insulated hutch in the back yard and test the battery endurance overnight. Powered by a 3.2V 400 mah LiFePO (Lithium iron phosphate) battery, FS2 remained powered up for just under 16 hours. (15 Hrs 50 mins) This is excellent news because the flight hardware will […]
While SpaceX’s Starman gets to drive through space in a luxurious Tesla Roadster, Flying Squirrels have to fly in Styrofoam class. The 1” thick Styrofoam enclosure will keep the flight electronics and battery warm in sub zero temperatures that are found at high altitudes. Our intrepid squirrel will also be wearing a stylish pink fiberglass […]
High altitude balloons are expected to drift, in the atmosphere. But Flying Squirrel #2 (FS2) has had some drifting problems of another kind. During construction as the FS2 flight electronics went from a breadboard prototype to final construction, a problem emerged. FS2 was not WSPRing clearly. In fact, it seemed to be more of a […]
Introducing our next intrepid sky traveler. The burning question of the Flying Squirrel #1 mission is “Where did it go?” and ultimately, “Where/when did it land?” So far the final resting place of FS1 has not been reported by anyone on the ground. It could be lost in the mountains and deserts of South […]
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, […]
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 […]
Intro Flying Squirrel #1 (FS1) is the first of a series of small high-altitude balloons (Pico HAB) to be launched based on a design of being very affordable ($50 or less) per launch using as much “off the shelf” parts as possible. FS1 does not have an onboard GPS so we will not directly detect […]
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 […]
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 […]
To get the telemetry signal on the air an antenna is needed. By necessity, the antenna must be light weight and simple. The size of an antenna is determined by the frequency we need the antenna to work at. The lower the frequency, the larger the antenna will be (There are exceptions to this rule […]
