Bandsaw Box Project

Project Brief

Here we are building a bandsaw box

Here are the skills we are learning and the constraints it needs to meet.

Reflection

The intended function of my Bandsaw Box was to hold various small candies such as Jolly Ranchers and Starbursts. I also designed my box to look like a car because i thought this would make it look better when i display it. My box is designed to look cool while still having optimal space to put my candy. To achieve this i chose a boxier car model for my reference, this insures i will have enough room for my candy when i have a lot of it.

One thing i am very proud of is the shape of my box. I think i did a fantastic job making my Bandsaw Box look like a car and i am also very proud of the color of the car and how the diagonal line came out.

One thing i believe i could improve upon is i would have liked to carve out fenders and add wheels to the box so that it could roll. This would make it easier to move around and slide across a table in you want to pass candy around.

One challenge i overcame during this project was the process of spray painting my box. Over the course of three days i spray painted over and over to get a result that i was confident and happy with. I struggled to get a clean straight line on the diagonal section. I overcame this challenge through persevering when i messed up and learning from my mistakes.

One skill that i learned during this project was how to spray paint. At the beginning of the project i was not good at spray painting and made many mistakes but in the end i was able to find a strategy that worked. I believe i could teach this to another student.

I think teamwork and collaboration helped me by showing me things i could do to improve my box. Specifically the other people that modeled there Bandsaw Boxed after cars.

Interactive Cornhole Board

Project Brief

We are building a cornhole board.

These are our learning objectives for the project. We were required to add at least two interactive improvements to our board.

These are the requirements and constraints. The cornhole board that we make will have to follow these requirements.

Electronic Prototype

Using a breadboard, i wired a piezo hit sensor and a beam break sensor to light up a neopixel strip. When the hit sensor it hit it will activate the flashing lights on the neopixel. The same thing will happen if you cross the beam break sensor.

1:6 Scale Model

This is a 1:6 scale model i created using cardboard and glue. I used onshape to design and lazer cut my dimensions. We then hot glued our breadboards with our neopixel, beam break sensors, and piezo hit sensors. This is where we tested our equipment and technology. My design was inspired by drew golf and their championship in

Wood Plank

Cut with table saw

Frame

I used the nail gun in addition to glue to keep the frame together.

Cut pieces

Cut by the table saw and miter saw

Wood Cornhole Board (snapshot)

Top View

To make the top of the cornhole board, I cut the wood with the table saw and used the nail gun alongside glue to secure it to the top of the frame.

Side View

For the frame of our cornhole board, we cut the wood with the miter saw. We also cut out the legs and then rounded them with the bandsaw and sanders.

Perspective View

This is the perspective view of the cornhole board. This includes the frame, top, and legs.

Neopixel Strip

The Neopixel Strip illuminates the board with a green underglow and turns off for 3 seconds when a bag is thrown into the center hole.

Bunkers/Sandtraps

The bunkers on the board and made with sandpaper which slows down any bag that slides onto it. Landing in a sandtrap adds 4 points to your score.

Final Cornhole Board Video

This is a video of our final cornhole board being used and played on. The LED lights are working and on. The bunkers are also working and stopping the beanbags from sliding on the board.

Infinity Mirror Project

Video of Prototype Working

This is a video of the prototype of my Infinity Mirror working with the neopixel strips flashing and switching between five different patterns I created in Thonny. The frame for our prototypes were created in Onshape and printed by 3D printers, we then lazercut arcylic pieces and put mirror film on them to give the infinity effect for our mirrors and neopixels.

Front

This is the front of my infinity mirror. I modeled the clips and front in onshape and 3d printed them. Mirror film and acrylic create the infinity mirror effect for the infinity mirror.

Back

This is the back of my inifinity mirror. It hold all the electronics for the mirror and was also modeled in onshape and 3d printed.

Side

This is the side of my infinity mirror. The sides were also modeled in onshape and 3d printed. After putting all of the pieces together. my infinity mirror was complete.
