5/13 weekly

This week was a very busy yet relieving one. I prepared for and presented my project. The presentation was a lot easier than I expected, and I was actually really comfortable presenting everything I had pride in building. My interview with mr. H was also really interesting because I liked the idea the school had of hands on projects and creating your learning environment.

Today I did an interview for mr. H. He asked a few questions about my classes, interests, and my work in isr. I was really interested in the schools new concept of them putting together the program for them to teach. I would want to look into that school more.

Today was my presentation. Im actually very happy with how it went, everything went well and I remembered everything I wanted to talk about. I even brought it all back to how it related to my proposal. Im relieved to be done with my final and all my projects.

Today was my last day to prepare for my presentation. I made a google slide with pictures of my projects and topics for me to talk about. I hope all goes well, im a bit more relaxed knowing its only going to be ms. petteys.

Today I scheduled my presentation with ms petteys. I donʻt have much time and I am a little nervous for the presentation, but I should be fine as long as I rememebr how it all connects to my proposal which was mechanical experience.

Today I went back online to find out if anyone on forums have had problems with the motor on the same model electric cart as me. I didnt get far, and when I tried to search for new parts I didnʻt find much either. When I looked up the model, itʻs deemed obselete.

Today I took a volt meter down to the carts. My plan was to check the leads on a motor and find out if any current was reaching the motor. How ever, my way to reach the motor was harder than i thought. In order to reach the motor I would need to pull off the whole body of the cart.

Today I went through the service manual I found last class. It took a lot of time to even find the electric cart section, majority of it was for the gas golf cart. In the electric section, there was no trouble shooting section which didnʻt help much.

Today I continued my work on the power supply. Iʻve finished wiring in the transformer and the circuit board. One problem I ran into was that I secured everything backwards, so I had to disconnect a few wires to enable me to turn the board around. Although some wires were twisted around eachother, it shouldnʻt cause any problems.

Today I did more work on the power supply. I didnʻt do much last class because the physics class was using the room, but this time I soldered more wires to the circuit board. Ive spent a few classes doing this now, its taking longer than I thought. It also took long because I put the board on backwards and had to redo it.

Final Weblog

Abstract: I am looking to expand my knowledge and experience in mechanical engineering and repair. I can start by working on the electrical golf carts at the energy lab and work my way up from there to more complex vehicles.
Title: Mechanical Experience Project a.k.a working golf carts
Background: I feel that this skill is important for anyones everyday life, but it is rarely taught. I work on alot of small engine vehicles; ATVʻs, motorcycles, mopeds, etc. but I know there is alot more I can learn. This project will expand my knowledge from gasoline engines to include electrical vehicles, including renewable energy vehicles.
Purpose: Gain knowledge of mechanics through experience repairing and upgrading two 48 Volt electrical golf carts.
Tools: Basic hardware (box wrenches, screwdrivers, etc.) Possibly a breaker bar, torque wrench and electrical equipment
Impact: The impact ranges from HPA to local. Finding a way to convert our conventional electric golf cart to run off of itself.. It will also give me the knowledge and experience that contributes to me becoming a mechanic or engineer.
Legacy: The legacy I hope to leave behind is to introduce students to a different form of science and engineering which is less common. To give students the knowledge that I believe to be a necessity in life, but is not commonly taught or excercised.

One person I collaborated with was sebastian. He was good with electronics, and I was good with mechanics and such, so it worked out well. On each project we were able to share our skills and knowledge with eachother and apply what was learned to each project. This helped alot with me learning a few things about electrical work, and I even learned how to solder. I havenʻt completely figured outmy schedule next year, but if I do come back I would really want to go more into fabrication. One thing iʻve really wanted to learn to use is a plasma table. Hopefully by next year or the year after we will have one. If I were to describe my year of isr to someone, it would be a long story. Starting with the idea of rebuilding a motorcycle and going all the way through golf carts, antennas, and power supplyʻs. I would tell them how I believe that I learned more in this class than I have in any other just because it fits the way that I learn- by experience.

This week I got a little more work done on the golf cart. Still havent found out how to gain access to the speed control. I also spent a lot of time preparing for my presentation.

Today we had a sub, but kama, vanessa, and I went into the conferene room again to practice. Im a little nervous for my presentation, but looking back at my work is reassuring. I have a lot to present, should take up alot of time.

Today I went into the conference room with kama and vanessa to work on our presentations. we interviewed eachother and asked questions. Iʻve been a little stressed about my presentation, but the more I prepare the more confident I get.

Today I got back to working on the golf cart. I was hoping to pull off the black plastic cover to get to the speed controller, but after spending the time to rip it off, i wwas just confronted by another plastic cover underneath it. After that, I just put it back together and pushed the cart in the sun because the charger is broken.

This week I mostly began to prepare for presentations. Itʻs starting to sound alot more complicated then I thought, so I think I should start planning some stuff early. Im gonna need to be prepared to display everything I did and explain how it all relates to my proposal. This might be challenging because my proposal started with motorcycles, and ended up with antennas and power supplies.

Today I was in class with the rest of isr and mr schorn. He had us write down some ideas to open our presentation and keep the audience engaged. Heres the stuff I wrote:


This is it. Time to see if all that time and effort I put into my power supply was worth it. I havenʻt done anything like this before. Iʻve disassembled and assembled complete motorcycle engines, but iʻve never touched a soldering iron until this project. Iʻve never done anything that uses work with wires either. That was the point of it.I went in pretty much blind on this power supply project. It took me a few weeks longer than Sebastianʻs did (which failed), so the anticipation was killing me. But once we plugged it in and flipped the toggle switch; No smoke. A great sign. It all checked out. For having no experience, I was pretty proud of it.


One person that did help a lot was sebastian. With my experience in hands on projects and his knowledge of energy, computers, etc. It worked out well. As long as we kept him away from the wrenches and didnt leave him unnatended near my ladder on the roof. Besides that, it worked out well. I needed help with energy and electronic experience, he didnʻt have much experience in hands on and mechanical work.


I learn by trial and error. The original idea for this was to work on motorcycles. I already know how to do that. However, I didnʻt know how to build a completely functional power supply. Now one of many things ive accomplished in this class. My purpose in this class is to expand my knowledge and working experience.

Today I watched a video, and began to plan out my presentation. I plan on talking about why I chose to take the class in the first place before introducing the projects ive worked on. I could talk about my interest in any mechanical, and how the original plan was a motorcycle.

This week Ive spent researching parts manuals, trying to trouble shoot for the golf cart. Ive also been checking forums in case someone has done the same thing before. I will also need to find where to order parts for the cart.

Today I went through the service manual to find the troubleshooting section for the cart. Next class iʻll have to take it apart and get working on it. The first thing I want to do is check the voltage going to the motor itself. If nothing is reaching it, then theres one more thing to rule out.
