Ved Marya

Hello Post

Hello! My name is Ved Marya and I use He/Him pronouns. One engineering strength I have is physically building parts and using machines. I am challenged when encountering anything to do with coding. as making sure every single line is perfectly typed whilst understanding how the code works can be challenging for me.

3 things to excel in Documentation

I want to make sure my pictures are nicely lit and very well cropped, with a plain background.
I want to be as detailed as possible when documenting what I have done, whilst still being concise.
I want to create a discernible timeline that clearly shows my thought process and progress as I progress through the class.

PCB Board Ideation

Avery and I chose to pick the eclipse. We thought it looked the coolest, and we thought it would work the best. Our second pick was Grogu, although because he is under copyright by Disney, we cannot choose him.

PCB Board

Avery and I made this PCB board, which is supposed to look like an eclipse. We put lights in a crescent shape around the "sun," and the switch on the "moon." One thing I will make sure to remember whilst working on printed circuit boards is that when two wires intersect, you have to be sure to put one onto the back of the PCB for the circuit to work.

10 Ideas

These are my 10 ideas for my speaker. The ones I like the most are the f-22 with the engines as speakers, the commercial plane engine with inside circuits showing, and the Loki-inspired "box." The box is cool because it is 'retro,' and I like that style. I am also into aerospace, and so I like the F-22 and Engine.

Post-it Feedback

Here is my post-it feedback for my two ideas for the exposed engine and Loki-inspired speaker. I think I might wait to incorporate the screen, an make sure to choose the colors of the box carefully.

Phase 2 drawing

This is my drawing of what is oging to be my final speaker. I belive that this will challenge my growth goals because I have two elements I have to code (the digital project and LEDs). This also challenges my 3d printing and modeling skills that i have to improve.

3d Model

These are a few images of my 3d model so far. I have modeled the main shape for the box, but I might need to make a few more cutouts and change the location of a few ports. I think the model so far looks good, I have made it possible to 3d print with no supports, and I am proud of my current work.

Cardboard Model

My idea is to make a fully functional speaker, with the ability to show the time, weather, volume, and look stylish all at once. I learned that I will not be using pressfit ever again, as it was annoying to make work and it doesn't quite look nice. I have to make modificaions for the holes I need to make that fit the LEDs on the top.

AMP Breadboard

Something that after working with the breadboard that I understand very well is the bluetooth device and how it connects to the rest of the speakers. It connects to the power and is relatively self-contained, though also connects to the main circuit via power and through the headphone jack.

Something that is a mystery to me is the voltage regulator, and why it connects to the potentiometer. In short, the regulator limits voltage to a constant 3.3V, so that it doesn't fry the circuit. It needs to connect to the potentiometer so that the potentiometer can change the voltage getting released into the speakers, therefore changing volume.

Something I learned whilst making this PCB is making the schematic correctly is very important, as if a few wires connect to the wrong places, the entire PCB will not work as it should.

AMP PCB

I worked with Hannah to complete this AMP PCB.

Unsoldered circut board

This is my amplifier circut board before I soldered it. I actually finished my soldering, though it did not work so I have to do it again.

Final Shaped PCB

Our original idea was to do an eclipse, and I think it worked out really well. I worked with Avery to complete this.

Soldered Amp PCB

This my soldered PCB board. I did one before but it didn't work, so this is actually my second one. Connected are the speakers, the potemtiometer, bluetooth, and my microcontroller.

Enclosure Build Process

I am on track to finish my project, and only have to screw the top in. I should be finished very soon.

My creation is an amplifier that can display all the information I need it to, while being relatively compact. I am most satisfied with my AMP PCB, because it worked perfectly after I did it the second time. If I was to start over, I would probably make a more interesting design, like an owl or spaceship. This design was relatively easy to execute and looks very plain. I will forever hold my skills and knowledge in soldering and coding, as those are two things I haven't had much experience in and had to do a lot for this class.

Final AMP

This is my final amplifier. My goals were to make an amplifier that would have a simple design that looked good pretty much anywhere, and I think I achived my goal. I was going to put lights at the top that would light up when the volume was turned up, though it was too hard to do so I scrapped the idea.
