Camera Field of View Test

-
Image
Objective: To test which GoPro field of view if most optimal for the side camera to record the tray opening and closing. Gaining footage of the horizon is also a secondary goal. Method: GoPro Hero 3+ Silver, the camera that will be used for the sides, was mounted in its casing and payload box to simulate recording on the day of the flight. A previous model of the petri dish assembly will be positioned at various distances on the side. A ruler was used to measure the distance of the payload from the petri dish assembly to record different distance possibilities. The camera was recorded at 1080p and 60fps.   Camera mounted into the new, lightweight casing.  Using a standard ruler to measure distance. Below is a diagram of all the possible frames of second and fields of view for each resolution within GoPro Hero 3+ Black, the camera that will be used for the top.  It has been determined for the side camera to record at 60fps at 1080p, in which t...

General We ran a new simulation of the flight trajectory using the CUSF Landing Predictor 2.5 and searched for the displayed landing coordinates on Google Maps. If launched today, the payload would land at 41.2763 N, 74.8146 W, which is in Sandyston, New Jersey near the Delaware River. If launched a week later on June 13th, the payload would land at 42.8818 N, 74.9573 W, which is in Warren, New York in or near Cullen and on a farmyard (amidst some hay bales). CAD The good news is that the lid has been printed. The bad news is that it is too thick to fit into the rim. Work is underway to fix the component's model and reprint it. Hardware & Software A new circuit board is being printed. Cameras We are testing the cameras in direct sunlight to determine if they will fail. We also reviewed the footage of prior launches to better prepare for the payload's retrieval.

General We are looking into other methods of analyzing meteor dust. In addition to using an electron microscope, we are also looking into: Spectroscopic analysis Titration Qualitative analysis of cations and/or anions. CAD Yesterday, we started printing the bottom holder component, but the 3D printer jammed roughly halfway into the print. Enough of the slot for the petri dish was printed for us to test if it fits, which it does. We are going to try reprinting the component today. We tried printing another copy, but the printer jammed again after printing the first few layers. A third attempt is underway. We are also reprinting the back parts of the camera casings. Earlier, we removed part of one of the walls of the components' model to resolve a clipping issue between it and the camera. We cannot incorporate this change into the existing prints of the component without risking the removal of the whole wall. Circuits We resolved some issues with the circuit boar...
