Tuesday 6/5/18
We begin our day finding a bird in our working room in the dental hygiene laboratory (S-327). The bird kept flying back and forth in the room creating a distraction. As Zack went downstairs to let public safety know there's a bird in the room, members of other teams joined us to help the bird leave the building. Zack returned stating that public safety advised to just let the bird be and that the bird will find its own way out.



We proceed to design the package with the petri dish mechanism. More ideas were exchanged. "Try to keep it simple," Professor Griffo stated about the mechanism. We need to 3-D print pieces for cameras.


The team is considering asking for access to the rooftop for experimental purposes. 


The team discussed the coding for the project while comparing it to the previous year's project's coding.


A member of the other team that came to safely capture the wild bird succeeded. The bird has been released back outside into the wild of its natural habitat at Bergen Community College.

Camera Field of View Test

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

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

During our last meeting we were able to get the Accelerometer and the Barometer soldered onto the protoboard, along with the Resistors that we will be using as voltage dividers. The sensors are being calibrated by placing the board into a position where only 1 axis should be measuring any acceleration from gravity. The voltage of that axis will be taken, and then the device flipped 180 degrees so the specific axis is now in the opposite direction of gravity. This will result in the voltages that represent 1g and -1g. The middle point will be used and the Zero Offset and the difference between the Zero Offset and 1g will be used as sensitivity. Peter is also debugging the program and is attempting to add an algorithm that will calculate velocity using the acceleration obtained from the acceleration sensor. We are also order some more parts in order to connect the protoboard to the beagle. We are ordering ribbon cables and connectors. Pin headers which we will use to create a connector t
