WELCOME POST

An engineering strength of mine is ideation. I find myself to be a pretty creative person, and I tend to have a lot of ideas when I'm excited to build something. However, with this, an area for growth is to be more organized with various aspects of my process. Because I have a lot of ideas, things can get messy and disorganized which can lead to a product I'm not fully happy with. I want to work on having a clear sense of what I'm going to do and executing that.

I can commit to:

Taking clear and high quality photos of my process
To be honest in my reflections and to include all parts of my process, even if they are failures
To keep a visually pleasant Google Site.

PCB IDEATION

Our 6 ideas were to make either a heart, boot, flower, cup, tree, or cactus. We decided to go with the cactus because of its unique shape and design. Our cactus will include 4 LED lights, and the switch and battery will be located at the pot part of the plant.

PCB COLLABORATIVE PROJECT

This is our final cactus design. We like how the cactus has an organic and unique looking shape and how the design looks smooth. I worked with Matthew on this design. I will remember how to make a parallel circuit.

10 IDEATION SKETCHES

I chose to favorite the human figure idea, the tree idea, and the sanskrit idea. I liked the organic nature of the human figure, and I thought it would be fun to make. I chose the tree one because it reminded me of the doodles I do in my notebook during class. I chose the sanskrit one because it is of my culture and having it in my room would keep me focused and peaceful.

IDEATION FEEDBACK

After looking at the feedback, I came to the realization that the human figure design would be too complicated. I think I'm leaning towards the om symbol one, as I think it could look really cool and it's something I could build with passion. One thing would be to add a more complicated element or another part to make it more fun to build.

POST PHASE 2 DESIGN

I think the design is realistic, but also has elements that will be fun for me to make. I want to develop my skills with the switch and LED, and I think that will be a challenge for me, but an achievable one.

MODELED ENCLOSURE DESIGN

This is my modeled enclosure design. It's gonna be a pretty simple box design, with press fit wood pieces. I want to add other designs as shown in my post phase 2 design, but I'm gonna do them by hand instead of the laser cut.

CARDBOARD IDEATION

This is my cardboard design. It was a little difficult to make because it was hard to "press cut" with cardboard, and also the use of tape made it more difficult. I hope that my laser cuts will be more exact, and I hope my designs look cooler, as I hope to burn it onto the wood instead of drawing with sharpie.

AMP ON BREADBOARD

I understand how complicated a simple function of playing sound is. I thought it would be pretty simple since playing music from my computer to my headphones or another speaker is just one wire but I didn't know that it needed so many other components.
A capacitor stores electric charge. It's a little bit like a battery except it stores energy in a different way. It can't store as much energy, although it can charge and release its energy much faster.

AMP PCB DESIGN AND SCHEMATIC

I worked with Zoe, and I learned the extent in which you can rearrange the schematic layout and have it still work the same.

Unsoldered Circuit Board

Final PCB

This is my final soldered and completed PCB. This original idea was to make a cactus that lights up with red flowers. I worked with Matthew, and I am happy with the product.

SOLDERED AMP CIRCUIT

This is my soldered amp circuit, that will be used to make my speaker functionable and able to play music.

Enclosure in progress

This is my enclosure, I finished gluing the peices together. They are more or less together, there might be some gaps though. I have to do my digitial project, add designs, and cut a hole for my battery.

FINAL AMPLIFIER

I made a wooden speaker, with wood burning drawings on it. On the right side was a Sanskrit symbol Om for peace, and the front was just freestyle designs.
I'm most satisfied with the fact that I was able to keep up, and also I think my speaker has a cool unique look.
Make the enclosure bigger so that the battery could sit in the inside.
To do things during class and take class work time seriously.
