ENGR 2192 Introduction to Making Spring 2025

Process For this project I knew that I needed to make something that I would actually use. I think I had the idea to build a shelf from the beginning of this project, because it is something I need. I will be using the shelf for all my little trinkets that don't have homes around my apartment. I started in Fusion360 creating the basic shelf design that I would build out of wood. This was pretty quick and easy for me since I am familiar with Fusion now. I also used Fusion to create the decorative parts of the shelf so I could laser cut them. I did two different designs, one is my own and one I traced over from a website. I knew I probably couldn't make an intricate design, so I figured out how to bring in a screenshot into Fusion and trace over it with the spline tool. I was surprised with how easy this was. Then I needed to make my own design, so I took inspiration from several shelves I saw online. I ended up creating a simple top piece with a little heart design in it. Little...

  Process This was my hardest project by far. I have long wanted to build a chess set from scratch, but finally have access to the tools necessary to make something pretty sweet. First, I worked on the board, which was no small challenge. Since I had no wood pieces large enough, I had to stitch together a flat piece out of 3 scraps of plywood. I used a biscuit joiner to get them to hold together, as well as a lot of wood glue. Clamping these together was tricky, but I used a set of 6 clamps to counter tension each side. Unfortunately, I didn't grab a picture of this step. I ended up with 3 almost perfectly even sheets of wood, but I had to use the pad sander to try to refine some of the seams and get rid of the bumpy edge. Here is a picture of the pre-sanded surface.   After finishing the sanding process, I used the DXF file I had from my board layout on fusion to laser cut and shade the squares. This required manual filling in of the shading pattern, but the end result was pr...

Process: I began my process by trying to create the general shape of what I wanted my dice tower to look like. I created 3 cylinders, each one smaller than the one below it. I then cut out a hole in the center of the cylinders to create the hole in which the dice would fall through, taking extra care to make the hole large enough for most dice to be able to fit in it. I then cut a square opening for the dice to be able to come out of, and a small ramp that leads the propels the dice from in the tower to out through the square opening. Using the sketch tool, I drew two slits on the bottom of the model to make room for the walls that the tower would connect to. Once I made sure the slits were the right size, I cut them into the model.  I printed this version out as a test, and found that the dice weren't coming out at a very high velocity, it was quite underwhelming. To fix this, I made the ramp more steep, and made the square opening a bit taller so that there wouldn't be so muc...

Process I started working on this project right when classes resumed after Spring Break. I had been messing around with small projects for my microcontroller (MCU), which I bought mainly to keep up with my Embedded class with Dr. Nickels, and thought it would be cool to do something with servo motors. My first attempt ended with me completely frying my  MCU  after I connected the servo directly to it, which is apparently a big no-no in electronics. By the time my new  MCU  and external battery pack arrived, I had decided to make a useless box. The first step, and definitely the hardest part, was calculating the proper timer values to generate a pulse-width-modulation signal of 50hz, which is what the servo expects to properly function.  Two servos, battery, breadboard, and MCU After I got the servos working, I focused on implementing an SPDT toggle switch using edge-triggered interrupts and internal pull-up resistors, which made things very confusing. I struggle...
