Bergen STEM Amateur Radio High Altitude Balloon (ARHAB)

We are almost finished with the payload. We finished the petri dish holders and cut holes in the box for the rods. We are did a mock assembly of the payload in order to weigh everything en masse. The payload weighs 8 pounds.

We finally have one of the compartments for the Petri dish. Unfortunately, it seems to be a bit too small, so we might need to either enlarge and reprint the model or file a few things down. The dish does fit if its pushed into place using a bit of force. Due to the way the holder was designed, the dish can only fit if its pushed in. The dish is essentially like a trapezoid (a bit like so \__/), thus in order for it to fit, the larger top side has to be pushed through the smaller bottom side of the holder. The motor mounts and the cover are being printed. We also finished the invitation form and sent it to Louis.

The components for the Petri dish holders are being printed and soaked. Zack updated the poster while Josh and Ian finished and submitted the AGU abstract. Joshua G. made the motor driver work. It is bidirectional and it was successful in driving a servo with the gear attached in both direction.
