WEEK FIVE: June 23, 2016

-
1. Tested battery eliminators and made sure that the GoPros run for at least 3 hours using an external battery. (Nick, Patrick)

2. Worked on trying to get the wire for the sound experiment connected to pin 33. (Billy)

3. Adjusted gain on mic/amplifier breakout board by turning screw counter clockwise all the way and then turning it back clockwise slightly. We used a tone generated by http://onlinetonegenerator.com/.
Maximum volume produced a voltage difference of 1.65 V. (Peter)

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 the possible fi

Camera Test in the Sun

Image
Last week we were able to test the GoPro cameras outside to see at what temperature the GoPro cameras fail, especially the top camera that would be directly facing the sun. The high was 83F in the afternoon, with several clouds in the sky. The thermometer cord was attached to the back of the top camera to record its changes in temperature. Attaching a thermometer to back of GoPro Inside Payload (Top camera connected to one power bank, side cameras connected to another) Setting up pole and payload so that the camera can record changes in thermometer. Results: 38900 Lux of Sun on Roof Top Camera (#1, Gopro Hero 3+ Black, 720p at 120fps): 98.2F - Initial Thermometer Reading at 10:35AM 116.8F - Thermometer Reading at 11:57AM 108.7F- Thermometer Reading at 1:16PM 36.5GB of memory used, recorded for 2 hours and 52 min (172 min) Side Camera (#2, GoPro Hero 3+ Silver, 1080p at 60fps): Temperature data not recorded for this ex

End of Week II of Summer 2 - 7/12/2018

End of Week II of Summer 2 - 7/12/2018 Our beloved mentor Professor Griffo will be leaving us for the next two week to take a well-deserved vacation. When professor Griffo returns we will only have about two weeks before we need to be ready to launch. This means that we, as a team, need to come together and work hard to complete as much as possible. Alejandro and Ian sat together with the professor to come up with a to-do list for the following weeks; this includes printing at least one completed petri assembly that has been tested, printing all casings, and generally getting ready for a launch in August. Progress Today, Thursday the 12th, we had to present our progress to the rest of the groups working here during the summer. The presentation went well, but we clocked in 7 minutes and 7 seconds from an allowed 3 - 5 minutes. Below is the presentation, if needed for further reference. https://docs.google.com/presentation/d/1whJQM1j4RCveDmQKPiAkz8o1wdrj7RuAVJhWfwd0pDA/edit?usp
