I've been working on preparing the design for production this summer, as we've now hit 10 weeks until I leave for Ghana. I've re-packaged the CAD model (Dragon 0.31) and uploaded it, but more importantly, the Google Drive Repository now includes PDF blueprints. This effectively marks the release of the design for public development, and I hope to implement more detailed assembly instructions and imagery as the design continues to evolve.

I've been working on assembling a copy of 0.31, using "basement power tools" level equipment. I'm not entirely satisfied with the system, particularly with the supports for the cam assembly. I'll be redesigning those and releasing a new update (0.32 probably) within the next week or two. However, I have assembled a case and functional front access cover, which exceeded my expectations. By using a sheet steel and end cap design, I've been able to reduce the thickness of sheet steel to 28ga  -- about 0.3mm. This has brought cost down by an order of magnitude, and makes cutting and bending components far easier.

While the incorporation of plywood has eased assembly and reduced the complexity of the model, I feel that there's still improvements to be made. I'm interested in replacing the endcaps with sheet metal angle brackets, perhaps riveted. I'm slightly concerned about accessible screws on the outside of the device, and using rivets would also solve that -- while I've designed the case to be impossible to access without access to the rear or the padlock, I'm concerned about encouraging petty vandalism with exposed Phillips Heads. Rivet guns are cheap and readily available in Accra, I'll want to make sure both options are possible. There's also currently unused scraps created from cutting out the case, I'm interested in reducing material requirements by using those.


I've done some initial hunting for sheet steel and other suppliers in Accra, and the results are promising. While I won't know for sure until I get there, it looks like many materials should be easier to find than I've feared.

Here's some pictures of things and such:

Last week, I gave a brief update to my small group about the "Meta-Project", which I had put a lot of effort into documenting the projects themselves. This week I am talking more about that and cleaning up the repositories, as well as a piece of an app explaining the ideas behind the framework itself.

This week was spent fixing a multitude of problems that seemed to come out of nowhere.

Most of the work went into fixing these bugs and resolving issues.

Some work was done on creating more sound effects for the game and creating music as well.

A little more tweaking was done on the anti-gravity mode.

The VR library we chose to work with is turning out to be more than we can handle at this point. We're switching over to generating the terrain and viewing it in a standard OpenGL viewer and also exporting it as an obj file to be used in other applications.

The latest commit on the repository includes the full implementation of the Shuttle Tracker feature among various other tweaks. The timeline for releasing version 1.0 on the Google Play Store is on schedule. The app should be released by around March 5th.

Other changes to note: The weather fragment no longer allows the user to change the location, but more importantly, it now uses the correct city of Troy, NY to display the data by default. Before this change, the actual city that was returned by the OpenWeatherMap API was inconsistent. Also, a license has been added for the project. I have chosen to use the Apache 2.0 license at this time. The version number has been bumped to reflect all of the major changes this semester.

There are some small tasks that I am looking to accomplish before releasing version 1.0 in May. I want to get a background image of the campus for the weather fragment to enhance the appearance of the app without bloating the APK. It is the first impression the app will have on the user since it shows up first, so special care is being taken in the selection process. I also will continue to test and debug any issues with the app as is.

In future semesters, I plan on implementing the RPI Directory and MorningMail features and also improving the existing Twitter, Athletics, and Events features.
