Group 061-08: Phone Charging

Weekly Objectives: The Week 8 objective predominantly consisted of getting a new housing printed. Furthermore, team members used a multimeter to test the voltage our design generated, and used an anemometer to test the wind speed in the channels of our jacket.  What we Accomplished: A new housing was fabricated via 3D printing and Creo-Parametric. The new housing is much more durable and sturdy than the prototype and will be used in the final design project. The housing has the same dimensions and is made of the same material as the prototype, but it wasn't 3D printed in two parts. As a result, the final housing will be able to easily withstand the pressure of the wind.  Experiments and testing constituted the majority of Week 8's Lab. Modifications were made to the AC motor to make the revolutions smoother. Also, a multimeter was used to determine the voltage our generator produced. After numerous tests, team members concluded that our generator produced 6 volt...

Weekly Objectives: After our initial meeting with Professor Jeong, it was necessary to produce a better prototype design that would better fit the design of the jacket. To do this, we will get the housing printed on a 3D that is capable of more accurately printing the housing, and in one print. Once this is done, we will meet with Professor Jeong again to talk about the specifics of our design and how it will be implemented into the jacket. After this, a majority of the building will be completed, and we will have to wait for Professor Jeong to finish the construction of the Jacket. What was accomplished: Unfortunately, we were not yet able to have the better looking housing printed yet, however, since the dimensions are going to be the same, we can still use the rough prototype for the fitting in the jacket. With this in mind, we met with Professor Jeong a second time, where we brought the physical rough design of the housing. In this meeting, we talked more specifically with Pr...

Weekly Objectives: The Week 6 objectives comprised of fabricating the housing for the fan and getting in touch with a Professor from Drexel School of Fashion. The group was split in two during lab as Justin and Anchit went to Drexel School of Fashion and Zen and Manpreet stayed in the innovation studio to fabricate the housing and work on the efficiency of the AC generator.  What was Accomplished: Week 6 was a big week in terms of the development of our eco friendly charging jacket. Zen completed the housing for our fan via Creo-Parametric. Needless to say, the team ran into issues 3D printing the housing because it was too big. As a result, the housing had to be printed in two parts and fabricated together into one housing. The team agreed that this would be a sufficient prototype for the housing. In Week 7 or 8, another housing will be 3D printed and used in the final project.  The team was put in touch with Professor Jaeyoo...

Weekly Objectives: The fan that was ordered last week has arrived, so our goal this week is to test the generating ability of that, and hopefully begin constructing the whole project. We were also able to begin communicating with someone in the fashion school, so we will try to begin discussing the specifics of the project with him soon. What we Accomplished: Unfortunately, after testing the new fan that we ordered to see if it could produce the necessary voltage, we determined that it could not. When spinning the fan to simulate possible airflow, we found that the motor, similarly to the last one, only produced around .1 volts AC, which is not nearly as much as we need. We figure that since both fans produced around the same number of volts even though they were two different fans, these fans must be designed to generate a current no matter how quickly they are spun. With this realization, we have decided that instead of using a motor from a computer fan, we will buy a small gen...

Weekly Objectives: We have ordered one of the new fans that was mentioned in last week's entry. We wanted to get one so we could test to make sure it will work well enough for us to use. We are currently waiting for that to arrive, then we can begin to assemble the electronic components, and then the full housing. We are also continuing to try to begin communicating with the head of the fashion design school. We have still not received an email back. We might try to contact someone else. What was accomplished: Unfortunately, we were not able to accomplish much this week as we are still waiting for parts and materials to be delivered. We have ordered the fans,  and also the plastic that we will make the housing with. We decided to use a high density polyethylene plastic as it is relatively lighter and more easy to machine than metal is. The material we ordered can be found here and here . One for the main body, and the other for the top of the housing. We plan on using a CNC ...
