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...

Week 3, Thursday

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.

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: https://bergenballoon.blogspot.com/2019/06/camera-test-in-sun.html
