The Othermill project has taken some time to do because of the trial and error I had to conduct. Organizing the circuit to fit into my star file in Bantam was harder than I imagined. I had to shift both the star and eagle file in order to finally fit them together after multiple attempts. Next, I brought the Bantam file to the printer and it took many tries to get the right file milled. As shown below, at first two stars were milled together weirdly. And this occurred three times before my fiddling with the Bantam file then created my actual project. (last picture) Once the copper plate was milled I began soldering. The spaces are small for the solder to hold the copper and it was difficult to only get the solder in that area, resulting in two more copper plates milled because the solder went over the boundaries on the first two. My project is soon to be finished after I get the smaller pen to solder.

For my milled object assignment I created a shooting star on illustrator with the shape tool. I then brought the svg into BantamTools where I made the shooting star ready to be outlined by the Othermill and I placed a rectangle around the picture for cutting. After putting the file on Othermill, my shooting star milled object was created.
As I am putting my final touches on my laser project I am content with the outcome. A challenge throughout my project was timing. Some tasks took more than I had expected, specifically my motor's circuit. I was troubleshooting a lot because somehow I had wired the circuit to make the motor buzz but not turn. I eventually created a working circuit by reviewing the directions multiple times and reconstructing the whole circuit until it worked. I'm not exactly sure what was misplaced but I believe it might have just been a wire in the wrong slot. It also took a few trials with my tree to get the right measurements and look.
Over the course of my project my ideas changed and evolved. I began with a stationary jewelry tree in a circular ringed base lit up by three LED lights. Now, I have a mobile jewelry tree with a microbit controlling the motor in a wooden box connected by a 3D piece. I designed the 3D piece to fit the bottom of the tree and top of motor to allow the tree to move easily. If I had more time to work on this project I probably would have combined these two ideas: adding the lights to the motor controlled tree. There would be two switches on the back of the box, one for the lights and the other for the motor. I would also work on the aesthetic aspect of the project to make sure I really loved the look by adding more details. I consider this project as a whole to be risk taking for a student. Regardless, in my work I created a motor circuit which I had no idea how to create and with this risk taking I was not afraid to ask my teacher for guidance. Also, I went ahead and drew my own tree which I then converted into an Illustrator file. I am proud of how the tree turned out. Overall, my project was a great learning experience where I was able to use many resources to create my mobile jewelry tree. Tools/Materials Laser Cutter 3D Printer Plywood Cardboard Stepper-motor Wires Microbit Breadboard Acrylic Batteries - My first and second prototypes are documented in previous blogs. - Below are the final stages of my project. Goal: To create an enclosure for the base of the jewelry tree that can fit all the circuits, and then to create the circuit. Since the first prototype, I have added a motor to my project which will rotate the jewelry tree. I worked with my teacher Ms. Dixon to create a circuit for the motor with a microbit. Unfortunately, I did not meet my goal because the circuit is not fully working yet. In addition, I created two different bases for the second prototype in order for me to see which one had a better design/fit for the tree and circuit. I like the wooden box better because it has a cleaner cut and good functionality. And I will also be placing three LEDs around the motor, as seen below: In conclusion, the base is finished and the circuit will be completed soon. Goal: To create a miniature version of the jewelry tree and its surrounding lights.
I created a simple copper tape parallel circuit with three LED lights in a triangle. For the tree I used a pre-made file from the Noun Project. After putting it into illustrator, I then cut the vector onto clear acrylic with the laser. I met my goal for my first prototype because I was able to create a smaller version of my vision for this project. I love how the lights reflect onto the clear acrylic and I'm excited to see how the bigger version will turn out. |
