Week 4, Tuesday

General

We are going over what we need for the tethered flight, namely what we have and what we need.

We also discussed what we are doing for "phase 2" of the HAB Project: launching hobby rockets from a high altitude balloon.


CAD

The second lid has been printed but needed to be sanded down. Otherwise, the second lid weighs the same as the first: 0.25 lbs.

We are also printed both of the gears today. Unlike the prototype assembly, the new gears can be back-driven without neither them nor the lid slipping. However, the motors by themselves could not provide enough torque to retract and extend the lid. This was remedied by overvolting them.


Circuits

We are continuing to test logging the data from the sensors.


Cameras

We have conducted another experiment with the cameras and compiled a report:
