A design/engineering strength I have is that I'm eager to learn and I'm a fast learner. An area for growth is definitely remembering Rhino.

A good reflection includes imformative and clear photos with informative captions. I think I need to focus on being detailed with my descriptions and reflections.

Board

Schematic

EAGLE

Pictured above are of Zach and I's schematic and board. The project was to create a schematic and board of three LED's in parallel. We completed it by first creating the parallel schematic in Eagle and then creating the board in Eagle. Creating the board layout in Eagle involved moving around and rotating the parts and then creating airwires between them. I learned about mapping out circuits and creating schematics.

DIGITAL JOINERY

This is a box made out of laser-cut MDF. It's held together only by the tabs, not any glue. Zach made it in Rinho and then cut it out on the laser cutter. We then assembled it by locking the tabs together. I learned how to attach materials together without using any adhesive.

CIRCUIT BOARD

This is our final circuit board. It's three LED's in parallel (more detail is above). I made it by sending the board schematic to the milling machine. After I milled it, I soldered the parts onto the board. I learned how to use the milling machine.

BREADBOARD SPEAKER CIRCUIT

This is my final speaker circuit on the breadboard. It has one test LED, two speaker that can play music, and a bluetooth module. The bluetooth module allows me to play music without plugging a device in. I learned about bluetooth modules and how they work and how to set them up.

These 2 designs are probably my favorite. They have XPS boards hanging from a MDF box. They audio excited would be on the back of the boards.

These designs are not my favorite. The top one is based off of the iPod HiFi speaker. The back would be open for optimal sound quality. The bottom one is just a cylinder.




10 PROTOYPE DRAWINGS

The top design is just a cylinder with ports in the side. The bottom one is supposed be the bottom part of a record player. The record would have the audio exciter on the bottom

I like these designs because of the space them but I don't think they look that good. There's a shelf that looks like Saturn with two circular pieces of XPS hanging off of it with the audio exciters.

I was trying to use the triangle shape in these two. I like the creativity of the bottom one. It's a box cut from corner to corner but then it's raised up.

FINAL 3D MODEL

I knew I wanted I wanted a mobile like design with hanging pieces. I also find a lot of inspiration from outer space and planets and stars, I based my lamp off of planets as well. The plan is to have the audio exciter to be facing down in the purple boxes (eventually going to be made out of XPS board) and the circuit board in the green box (eventually going to be made out of MDF). The planets will be cut out of acrylic and hung from the box using fishingline, and the XPS boxes will hung from the MDF box. I wanted a speaker that was almost like an art installation and I think this was a super creative way to do it. I choose this design because I was most excited about it and I think it looked the coolest.

FINAL SCHEMATIC AND BOARD

On the left is my final schematic for my speaker. It includes the circuit for the speakers as well as a test led and bluetooth. This was then milled which is what is seen below.

CARDBOARD PROTOTYPE

Pictured is my final cardboard protoype. It represents the scale of my final product. The only difference from this one and the final one is that it would be against a wall, it would be hanging from the underside of a soffit.

FINAL SOLDERED CIRCUIT

Pictured is my final soldered circuit. This is what is controlling the speakers inputs and outputs. I learned how to match the schematic to the milled board. This was also very challenging for me. Finding out where to put the components was a lot harder than I thought it was gonna be.

FIRST CUTS

So far, I've made one planet. I used the laser cutter to cut a circle out of green acrylic and then used the vinly cutter to cut out a stick of the ocean to stick onto the acrylic. I have yet to make everything else. I think my next steps will be to cut out the rest of the planets.

ENCLOSURE PROGRESS #1

So far, I've completed the rest of the planets and I have finished my MDF box that will hold my circuit board. I am planning on cutting my XPS board next.

ENCLOSURE PROGRESS #2

I've completed one side of my speaker and have created the box for the other side. I didn't think my speaker through and didn't laser cut a hole to thread fishing line through, so I had to drill a whole through each of my planets. The planets are attached with fishing line. I also figured out that I just forgot about a planet, Venus no longer exists in my solar system. However, I may add it. My next steps are to finish the other box and install it in my room!

I mounted the enclosures to a soffit in my room with velcro. Eventully, the wires will not be visible because I'm going to drill a hole through the soffit. The MDF box enclosuing my circuit is sitting above.

FINAL REFLECTION

I'm really satisfied with the overall outcome of my speaker. I think it's really unique and I haven't seen anything like it. I'm not sure if I would change anything about the overall design if I started over again but I would've added venus to the final one. With both my lamp and this project I haven't been super ambitious with a design, it's mostly been a lot of boxes which I think is the best thing to do. It allows me to be able to finish projects on time. However, with both projects I've been extremely happy with my final outcome.
