Week 4, Monday

General

We discussed general issues and status updates regarding the subdivisions of the HAB Team. One of the topics discussed was the risks to the electronics onboard the payload on landing as well as the risks to ourselves depending on where it falls.

On a similar note, we set up accounts and channels for Slack to improve communication between teammates.

Professor Griffo and Ian looked over and updated the 2016 checklist so that it applies to our current project. It includes everything we need and directions for launch. We still need to go over the checklist to make sure we still have everything in the toolbox or if we need anything else.  

 We are also deciding on the parameters for the upcoming tethered flight.
CAD

We refined the newer print of the lid to reduce its thickness and width. These issues were likely because of the slicing software and/or printer rounding to the wrong measurements. We sanded down the sides of the lid in addition to reprinting the component with reduced layer thickness. The sanded copy now slides in and out of the rim with little to no resistance.



 Additionally, the models of the camera housing and casing assembly presented a clipping issue in Fusion 360. This was resolved by removing 1.8 mm from the inner right wall of the back part of the assembly. Similar to the front part of the assembly, it may be faster and cheaper to incorporate the change into the physical copies by sanding the removed portions away.


Circuits

The code for logging the data has been completed. The complete circuit board has been assembled and we started testing all the components.

We are also trying to figure out how to accurately read altitude via the onboard GPS devices. That said, we may need to renew our subscription for the Spot GPS services.


Cameras

We discussed possible camera mounting solutions, which include using a different casing system entirely.

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

General We are taking inventory of what we need for the tethered launch. CAD We have made revisions to the bottom holder and rail components of the dust capturing system and are going to start printing one or both pieces of the assembly today. We are also sanding down the newer lid to reduce friction and add clearance. Circuits We are still testing how to compensate for the motors' low torque. The two methods we are considering are using a higher voltage to yield more torque and using two motors per assembly and have them operate slower. Cameras We are trying to determine if aluminum and/or mylar foil will aid in reducing heat buildup as initially hypothesized. Of the websites and reviews read, it seems mylar is the better solution. It is more reflective, provides more insulation, and is lighter than aluminum foil.
