The blue layer, for instance, is a metal springer that will be inlayed into the surrounding ply- wood so that it won’t bend too far and snap. These are all projects that I am currently involved with that are being supported by Gonzaga and some of its clubs. The trebuchet is a floating arm trebuchet and is about 8 feet tall. We have yet to test it but are getting very close as you can see from the pictures above. I am also involved in getting custom longboards made, as we plan to make about 20-30 of them with Gonzaga logos and sell them to earn money for the ASME club. The other projects, Blimp, Derby car, etc were in the planning stages last semester but should start to come to- gether and be quite successful as the semester progresses. 1
- 2. Zetec, Inc: Summer Manufacturing Engineering Internship During my internship at Zetec last summer one of my projects was to design and build a new ASIC board testing fixture to solve problems associated with the old fixture. The new fix- ture had to be more consistent with its testing because the old one had been shown to let bad ASIC boards pass the quality control test. To do this, I had to make the board holder spring loaded and adjustable in the XY plane. I also had to make the probing pins come down vertically using a die set along with many other much needed improvements. The previous text fixture. My final design in SolidWorks. Although I had lots of helpful advice from my supervisors, I was given this project and left alone to complete it. As a result, I encountered many problems, but gained an immense amount of knowledge and experience from it concerning machining, suppliers, scheduling, design and just generally working with a wide range of different types of employees to com- plete a project. After it was finished, I was very happy with my work on this project as the end product was successful, and all of my designed parts worked with some modifications. This became very helpful in keeping costs low since I didn't have to remake any of the parts. All of these designs were eventually created using SolidWorks, although some initially began as AutoCAD and inventor files before I was able to get a license for SolidWorks. 2
- 3. I had to create a new toggle clamp as the one I started with didn't have a long enough draw or enough lever- age. To keep the ASIC board secure without making it difficult to replace the boards, I used spring loaded plungers. I included this in order to show scale as the ASIC boards were only about 14 by 6 mm. All of my designs had to work The previous fixture had the probing pins glued in so together and line up very accurately for it to work right. that they could not be replaced. My design secured the pin sockets and allowed the pins themselves to be easily replaced. Instead of ordering a die set it was determined to be cheaper to just have me design my own. This was because it would have to be machined in the end by me either way. My first design did not work as it locked up when the Another design challenge was that it was to be used die set moved, but after adding a third post and much in heat testing and so all of the components had to longer bushings it worked just like was supposed to. be tolerant of high temperatures. 3
- 4. Eastlake High School: Senior Project While most kids decided to learn photography or cooking, I went far beyond what was required of me and created my own electric motorcycle. This was my first major project where no one was holding my hand to help me through and so it is my pride and joy. This pro- ject showcases many of my engineering talents as it required me to be creative and resource- ful through its entirety.

After several months worth of research I began ordering components and putting to- gether the bike. The frame had to be highly customized in order to accommodate its new power source and this required lots of designing, machining, welding, thinking and rethinking all to be performed by myself. I spent countless hours studying wiring diagrams and com- municating with manufacturers about how to wire everything and this was a struggle for me as it was completely new. In the end, all that hard work paid off not only because I passed my senior project and graduated, but also because I came away with an all electric motorcycle capable of a 22 mile ride that at the time you couldn't go out and buy. Ammeter and voltmeter, not your average motorcycle gauges. Another look at how everything is mounted internally. One of my better welds. 4
- 5. The old charging setup. Programming the motor controller via laptop. I still consider this bike an ongoing project as I have continued to work on it ever since I started way back during my junior year of high school. Some of the improvements I have made include adding a gas tank shell to make it look a lot more presentable and changing from individual battery chargers to one single 48volt onboard charger that allows me to plug in anywhere and charge up the batteries. I also added in regenerative braking a few years ago. My project mentor. My bike in action! 5
- 6. These two projects of restoring a dune buggy and building a mini chopper were both from long ago during high school and junior high. They were really important to me because they were both projects that were very hands on and they allowed me to see how much I en- joy working on mechanical systems. It didn't hurt that I ended up turning a profit at the end of both projects either though! Lifestyle: While I do believe that I have too many hobbies and far too little time, I am and have always been very passionate about motorcycles. I have grown up with them and have been lucky enough to enjoy them all of my life. This passion has lead to an extensive background in maintenance and repair, and this has certainly played a major role in shaping my mechanical engineering interests. Dirt biking has also given me the opportunity to explore some of the coolest places on earth such as the lagoon in the picture of Baja, Mexico shown above. My mechanical engineering interests have also lead me outside the country as I was given the chance of lifetime last spring to study engineering in Florence, Italy. While in Europe, I trav- eled to 13 different countries and learned more than I could ever imagine about the world we live in and the multitude of people that live in it. After just one day in Morocco, I was com- pletely blown away by ingenuity of the people who had everything from beer cans as gas caps to dirt bikes with pedals for when you can’t find or afford gas. Everywhere in the world there is an opportunity for engineering and that is why I love it. 6
