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.  

The Arduino based payload measured time, acceleration, magnetic fields, orientation, temperature, pressure, light intensity, solar panel current, and solar panel voltage. It was capable of self regulating its temperature with heaters, orienting its SPOT GPS upright with a custom gimbal, and dropping a payload at a specified altitude with a stepper motor.

SSI-23 was launched from a park near 2093 San Juan Drive, Hollister, CA at 11:39AM. The conditions were not too sunny or windy, providing a great start as the balloons were picked up by the easterly drafts.

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. Despite this, the payload never fell apart, and it successfully flew 155.10 kilometers East at 79°.

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