What We've Been Up to...
On the 4th of February, the Colorado Eclipse Team met to work on a new design for the Live Video Payload. A rough design (pictured above) was our starting point as we worked to position and balance the components of the Video Payload in a small insulated package. While we were working, the printer was hard at work producing spare 3D printed parts for use as backups in the event of part failures. In addition, we are working to integrate a power management system into both the Still and Video Payloads to prevent loss of data. We will be using SparkFuns LiPo Fuel Gauge to keep tabs on our batteries during flight and, if necessary, perform a "graceful shutdown" in the event of a battery failure.
On the 4th of March, the Colorado Eclipse Team continued working towards the completion of the L.V.P. The final design had to be enlarged by 4% to accommodate for insulation requirements. The L.V.P has a final dimension of 13x13x26cm and a mass near 850 grams. The exterior Pi Camera housing was also redesigned to allow mounting of the housing directly to the structure of the payload. The L.I.T.P. was "refreshed" after prolonged storage. This included replacing flight hardware, examining operation of O.C.C.A.M.S, performing scheduled maintenance on the LiPo battery, and inspecting the structure for damage. This marked the completion of the L.I.T.P. Design and prototyping of the S.I.P began and we are working out the best methods to pass a flight tube through the ground plate of the transmission system without compromising signal integrity. We have selected components for a sensor package that will fly with the L.V.P that will not only log environmental conditions for later review but will also allow us to access this data live on the ground.
On the 11th of March, the Colorado eclipse team completed work on the L.V.P. marking an important step towards completing a milestone. We also continued our work with the S.I.P. which is nearing completion as well. Once all three systems have been completed and tested, integration of a new tracking system will begin. This tracking system will allow us to receive payload position updates every 5 seconds which could improve signal quality from the L.V.P. The Colorado eclipse team was joined by two students from Arapahoe Community College (David Colclazier and Maggie Franchois) who will continue to shadow and learn about the systems and provide support moving forward. This will allow multiple system specialists to be available in the event a team member becomes indisposed. This will also increase our ability to complete new milestones regarding the testing and integration of software and hardware improvements. T-23 Weeks!
