The Arduino based payload measured time, acceleration, magnetic fields, orientation, temperature, pressure, light intensity, solar panel current, solar panel voltage, and was capable self regulating its temperature with heaters and dropping a payload with a stepper motor.

Once the rope was cut, the balloon accelerated upwards, and immediately began to spin on its horizontal axis, an unforeseen consequence of the selfie stick.

It ended up in the University of California Agriculture and Natural Resources experimental range, which was interesting given our choice of decorations.
