One Engineering Strength I have is my willingness to listen to other peoples advice and feedback.

One Engineering Area of Growth for me is my inexperience with circuitry. I also think that I can struggle with coming up with creative/ambitious enough ideas.

The 3 things I want to focus on this semester:

Improving my knowledge about circuits.

having creative ideas.

Executing my ideas.

Shaped PCB Ideation

We chose to the bear because its a fun animal.

Shaped PCB design

Speaker Design ideas

Design Feed Back

The most valuable input I received was about the low rider. The importance of adding unique elements to the actual low riders was something I had not considered.

Phase 2 Drawing

I chose to use a different idea for my final drawing. I found myself struggling with adding details to my other ideas so I went this idea. This will help my growth because this idea is more complex than my others ideas, so i'll have to be creative in order to execute my ideas. I'll also have to use a lot of Rhino to finish this design which is something that I haven't done a lot of.

Rhino Screen shots

This is the 3dm model I have. I plan to 3d print the body the crane, I want to add a hook that actually attachs itself to the speakers.

Cardboard Model

My idea: A construction crane speaker

Learned: The crane speaker is too large and that I need to make smaller.

Circuit Board

I understand the the positive and negative charges.

I didn't understand what the capacitor did but after looking it up I understand that stores a small amount of energy and releases if there are any breif interruption from the power source.

AMP PCB Design + Schematic

For the PCB design I learned the importance of an intuitive layout for pathways connecting everything.

Amplifier (Unsoldered) Circuit Board 4/24

Shaped PCB

I worked with Angie on the original design. It's a California Bear. I like how it turned out.

Enclosure Fabrication

I am fabricating a crate. I haven't support. I need support 3d printing. The crate is be press fit. I have also left an opening of the speaker. This is just one half of the design the other speaker will go into a another box which is why there is a hole. I also need to start actually working on building the enclosure.

Amp Circuit

Final Amp Document

My goals for this amplifer were to: make a crate speaker. Have the amplifer work and finish the amplifier. I managed to achieve all these things. I'm most satisfied by finishing this project and be able to use a speaker long term. If I were to start again I would have used my in-class time more effectively. What will stick with me is the knowledge that I can achieve more than I expect even if I think I am not good at it.
