Welcome Post
A design/engineering strength area for growth:
I've been wood working since I was a little kid- I first started taking classes with my dad when I was maybe 5. It's a passion for me ever since.
An area for growth:
I think my ideation stages and finalizing my project design are areas for growth. I find that a lot of the time I'll be very committed to a singular idea but will end up changing things along the way- usually those changes are small though.
Three things I want to commit to in the documentation of my learning and projects:
I commit to taking clear photos of my work to visually show my progress.
I commit to providing good context for what goes on in the pictures I add.
I commit to making my page show the progression of my learning and the culmination of my work
8/29: PCB Idea Drawings
Above are drawings of my ideas for the PCB. Mayen and I ended up choosing the watch design after using a randomizer to pick between her top design and mine.
9/3: Fusion Schematic and Breadboard
*note there is a switch in the schematic above I just forgot to put it in when I took this screenshot
Above is the PCB schematic in Fusion and the breadboarded model that I created with Mayen. For the breadboard I only used 6 lights instead of 12 because it is a parallel circuit and doing all 12 seemed a little too repetitive. The board layout, in the shape of a watch, has the LEDs in place of where the hour numbers would be. One thing I will remember about PCB design is that there is a top and bottom of the PCB where the routed lines will be.
9/9: Speaker Ideation Sketches
The 3 circled designs are my favorite: speaker person, snowman, and football. I like these the most because I think these will look cool in my room and I'd be able to build these while maintaining pretty good sound quality.
9/11: Ideation Post-its Feedback
Takeaways from my classmates' feedback:
football design is more doable
might have trouble with the balance for the figurine design (yall just underestimate my abilities)
9/13: More Detailed Drawing of Lamp Design
no longer going with the football idea
added the blue acrylic base to the design for support and to look like water
planning to have the wire run through the body and out the acrylic going to an outlet instead of a battery
for the wood for the speaker encasement I'd like to use mahogany veneer or walnut if mahogany isn't possible
9/25: Modeled Enclosure Design
I ended up changing my design to a speaker box mounted atop a column. The base of the enclosure will be laser cut acrylic either in blue or green to look like water or grass (not sure which color I will choose yet). I will make two of these- one for each speaker.
9/27: Cardboard Prototype
I laser cut the pieces for the top and bottom from my rhino model and hand cut the pillar in the middle (the actual column will be 3d printed and I wasn't going to try to make the intricate details out of cardboard)
From making this prototype, I feel pretty confident in making the final product. Most of it will be laser cut which is pretty straight forward and the 3d printed column will hopefully print without any issues.
10/3: Finished Amplifier Breadboard
(added bluetooth)
After doing the breadboarding I feel like I have a decent idea of how the circuit works and how the amplifier works
11/1: Finished Amplifier PCB, Design, & SchematicÂ
I worked with Tyler on this
I learned that increasing the width of the connecting lines on the PCB and adding a ground layer to the top and bottom will increase sound quality
11/19: Soldered Amplifier PCB
12/4 edit: I had the button soldered to the wrong place and I fixed it by replacing the switch with it (I'm not going to have an external charging port)
12/4: Finished Intro PCB Project
The original idea was for the pcb to look like a clock
I worked with Mayen
I think it turned out pretty good
Enclosure Process
12/4: Finished Amplifier
My amplifier features two matching towers mounted on a corinthian pillar on a blue acrylic base (meant to look like water)
My amplifier will add to my surround sound system at home
I am most satisfied with how I stayed on top of my work and planned the design and building process
If I were to start over I would maybe have added more components to the enclosure given the fact that I had a lot of time left over after I finished
I learned the basic principle behind how amplifier/speakers work and I think that's pretty interesting so I'll probably remember that
