Hello Post :)
A design strength: A strength I have in engineering is my attention to detail!
A design weakness: A weakness I think I have is my need for everything to be perfect and as I saw it in my head.
Three things I want to commit to for documentation:
1) To describe each project in detail.
2) To take lots of photos for documentation.
3) To keep my page organized and easy to understand!
8.29: PCB Ideation!
These were our 6 PCB design ideas. The ones on the left are mine and the ones on the right are Raul's. We ended up going with the F-22 Fighter Jet. It's going to have 8 LEDs, 8 resistors, a switch, and a battery. The circles on mine were supposed to be LEDs and the lines were supposed to be the resistors.
9.5: PCB documentation!
This is our final PCB layout (in 3D and 2D) and our PCB schematic (in digital and breadboard form). For this Raul used Fusion to model our PCB (Printed Circuit Board) and our schematic, and I put the schematic on the breadboard to demonstrate what it would look like in real life. Now, our layout will get sent to get printed and then we'll solder all of the different pieces on it.
9.10: Speaker Ideas!
These were my design ideas for our speaker project! I felt like I couldn't come up with any good ideas until we did an ideation session with Mr. Kleindolph in class and I came up with the idea of a watermelon cut in half that I'd put the speakers and wires inside.
9.12: Ideation Feedback!
This is the feedback I got from presenting my ideas. I think I'm leaning more towards the cherries or Lily's idea of making the speaker into a fruit basket to incorporate a lot of different fruits and I don't have to pick. I don't think I'm gonna do the watermelon because it's complex and I couldn't exactly figure out how I was gonna do it.
9.23: Phase 2 Ideation Drawing!
This was my 2nd attempt at doing my speaker drawing in more detail. We were supposed to figure out what material we wanted our project to be in, but I think I'm going to 3D print the sides and cut the front and back out of wood.
9.26: 80% Finished Rhino Model!
After we did the phase 2 drawing we started modeling in Rhino, and then, once we're done with our Rhino model we will move to modeling with cardboard. Right now I have the middle, the back and the front. The middle is going to be 3D printed and the front and back panels are going to be made of wood. The actual cherries and the stem itself are going to be made of acrylic. All that's left to do is measure out the volume and charger buttons, and make the stem for the cherries.
10.8: Finished Cardboard Prototype!
My idea is to make cherries around the outside of the speaker holes and for the stem to be shooting up kind of like it is in the photos. When making my prototype I learned that instead of wasting time attempting to cut everything out I should laser cut everything and it would have made my life a lot easier. I have to alter the cherry stem in the final product and add a dip in the circles to make them look more like cherries.
10.22: Breadboard amp documentation!
Because I have spent time building the circuit board I got a better understanding of how breadboards work and how the connection across the breadboard work. The one thing that sounds crazy to me is how just the plugs connecting to the speaker can make the whole thing work, and that if you plug something in wrong, the speakers wouldn't work.
11.2: Amp PCB design and schematic!
I worked on the Amp PCB design and schematic with Marcel! Something I learned was how to organize the different components! I knew this mainly because there were a lot of things that needed to be connected to one ground point, so I had to be able to make it all work/connect.
11.20: Amplifier Circuit board
This is how my amplifier circuit board turned out! I accidentally soldered the part that I plug my battery into onto the board before I saw this assignment so ignore that, but this is what it looks like! My partner and I are super proud of it, and Mr. Kleindolph even wrote "Mari-cel" in the corner!
12.3: Soldered PCB Project
As shown in a few posts above, the original idea was to make a fighter jet that lights up. I worked with Raul to design it, and then we soldered the lights, the resistors, the switches, and the batteries in on our own. I'm pretty happy with this, except I forgot to add the last light in the upper left corner.
12.6: Finish Amp Circuit Board
This is my finished circuit board! As I said earlier, I worked with Marcel on the board, but I soldered it all together. The chip thats plugged into the board is Bluetooth so that the speakers will connect to my phone without having to plug my phone into a dongle. I worked so hard on this circuit board and I'm so proud that it's done!
12.12: Enclosure Build Process
This assignment was just posted when I saw this, but this is the only picture I have of my actual enclosure build :(. Here is a picture of the 3D-printed part of my project! At this point in time, I was on time to finish my project before the semester, and I no longer had anything else to do, but when I took this picture, I still had to finish my circuit board, laser cut my cherries, laser cut my stem, superglue the top, put magnets on the bottom, and screw in my speakers
12.12: Final Amplifier Documentation
I made a cherry speaker! The red rings are supposed to be cherries, and the green part is supposed to be the stem. I am most satisfied with the speaker; it took so much work, and I'm proud of it. If I were to start over, I would pick a darker-colored wood that wasn't plywood (probably mdf) and choose black washers instead of silver washers. I learned how to make an amazing circuit board and that the long leg of everything is always positive! I really wanted my speaker to look cool and be something that I could be proud of, and I definitely am!
