It started with a problem: pets sneaking into the room uninvited, leaving unpleasant surprises. The best way to get around this would simply be to leave the door shut. However, we wanted to automate this process. Our goal was to use rubber bands
to that end.
The concept behind our project would be simple: as we open the door, energy is stored in the form of elastic potential energy through the rubber band, and upon release, transferred to kinetic energy, shutting the door. Given the force exerted is proportional to the displacement, in theory, this should shut the door no matter how far we open it.
We approached this several ways. The first was to simply attach a rubber band from the top corner of the door to the wall. Though this solution proved worthy in functionality, it lacked visual appeal, longevity (bands broke frequently), and complexity.
In order to hide the elastic bands, we installed them in between the door hinges. This however failed to exert the torque required to rotate the door shut. Considering the laws of rotation that were discussed in class, we concluded that this problem was due to
a combination of a relatively small radius, and the obstruction caused by the bands between the hinges.
The third solution would end up being our final. Not only was it promising, but it excited the group in terms of design. The idea was to attach a wheel mounted to a bracket on a door. An elastic band would then be attached from the door to a hook on the axle of the wheel. As the door opens the elastic band stores energy which is
transferred to kinetic energy upon release.
Over the course of this project we were faced with many issues. From failing elastic bands to lack of torque, we incorporated the engineering process to solve these issues we encountered. For instance, we added tape onto the axle to increase the radius and ultimately, the torque. This was a very simple solution, yet it had a significant impact.
Another issue we encountered was the threading from the axle (hex bolt shaft) was grinding against the mounting bracket creating a great deal of friction. Our solution was to add bearings, using nuts to secure the inner race of the bearing. Though the initial plan was to drill a hole in the bracket in order to achieve a tight fit, we had to reach out to someone in order to have the bearing welded to the bracket.
Each team member contributed in a different way, which is ideal for a project like this. While some were oriented in the application of theory, others were more focused on the actual fabrication of the apparatus.
The results were very rewarding. Hours of work dumped into the project felt validated as we were able to experience our device functioning first-hand. Though improvements can always be made, we reached our goal: to use rubber bands to automatically shut a door when opened.

How about some softball? Finally had a chance to try out the new D500 at a game. The D4s still is a low light king, but the D500 is great for everything else.
Trying 'Shoot From The Hip' again. Honestly, to get the focus, it depends on your luck.. I always burst about 7 shots in one object, and then I choose one photo that I think is the 'best' photo..
Just finished the 'Science Of Food Crops' test today..

Ross School seniors learned about traditional and modern dances in China in the Senior Lecture Hall on March 30. Barbara Tjiong, the principal of the Plainview Chinese Cultural Center, along with seniors Allison Bauser and Yi Ying Zhu, demonstrated the graceful ribbon, umbrella and fan dances. The students were then shown videos of contemporary Chinese music and dance. The presentation was part of their studies on China of Today, specifically on how Western society has influenced the country.
