Lantern

Brief

Research

Pattern:

Idea Development

4 different types of lantern ideas of drawing

We did this research before so, we chose four from that research and drew the drawings.

My lantern template

This is the handout where we drew our designs for latern

Prototype

My Prototype on Onshape for my desgin

My protype of my drawing on Onshape before we laser cut it using Gloforge. I chose a flower desgin for my lantern that was on a circualr pattern.

Evaluations & Testing

Final Product

My Lantern

This is our final product of our latern it has the laser cut pattern of my flower desgin and the it is on cardboard and we constructted with cardboard, hot glue, and scissors.

Coaster Project

Task: For this project, we will create four coasters out of different varieties of wood as a holiday gift for our family and friends.

Proccess Documentation:

Gather the pieces of the wood you desire
You then cut them down to a length that you want each of your pieces to be using the miter saw
Then, you run it through the table saw to get your desires with the wood.
Then you dry fit your wood so you can get the design you want for your coaster
Next, after your dry fit you do your glue up and clean up any leftover glue off of your wood
Then you clamp your wood and let it stay for 24 hours.
Next, you run it through the planner for your desired thickness
Then you run it through the table saw to get your coaster sides
After, You sand down your coaster
Finally, apply the finish to your coaster

Sketch:

Idea Development

This is my sketch of my idea development. I did a 4x4 coaster. I have done Oak, Maple, Purple Heart, and Padnuk. I used 4x 1/2 for Oak, 2x 1/2 for Maple, 3x 1/8 of Padnuk, 2x 1/8 of Purple Heart, and the Oak by 2x 1/2. I loved making this design for my coaster and can't wait to see the end product.

Table Saw Documentation

Before: Table Saw

This the wood that we are using before we cut it into 1/2, 1/4, 1/8. It is thick and is not the the same width.

After the table saw

After the table saw , the wood was cut into 1/4, 1/2 and 1/8th into different withd's

Glue Up:

Glue Up

This was a glue- up, using the wood we chose from our sketch that we glued up together to create a coaster.

Planner

Before Planner

This is one side of my wood after the glue-up. Next, I am going to put my wood through the planner ,so it will be a uniform thickness.

Before Planner

This is the other side of my wood after the glue-up. I am also going to put this side of the wood through the planner so it can be smooth and uninformed.

Table Saw

After Planner/ Before Table Saw

After the planner, my wood was smooth and soft. Next, I will cut my wood into four pieces 3 inches wide. using the table saw.

After Planner/ Before Table Saw

This is the other side of my wood, This is after the planner and before I table saw my wood will be cut into four pieces all 3 inches wide.

After Table Saw

After my wood went through the table saw, my wood came out straight and in four pieces that is 3 inches wide. I made coasters

After Table Saw

This is other side of my wood , The table saw cut it into four pieces,straight, that is 3 inches wide.

Routing

Before Routing

This is before routing as you can see the coaster have sharp edges that we do not want, but they are smooth and pretty.

After Routing

This after routing there are no more sharp edges and they are ready to be finished. They are now coasters.

Finishing

Before Finishing

This is before putting finish on both sides of your coaster. The coasters are smooth and have no sharp edges so, I am now ready to put the a coat of finish on my coasters.

After Finishing

This after finishing you can tell the coasters are glossy and now they can be used as coasters.

Final Product

This is our final product of my coaster project they all have finish on them and are now ready to put your drinks on them. I love this project

Reflection Questions

I am most proud of the design of my coasters I love that I have accents of purple heart and padauk with oak and maple.
The one skill I have mastered is glue-up, and that was so much easier this time. I was more confident in completing the glue-up, and I would love to teach somebody this skill.
This coaster project compares to my lantern project I enjoyed both and they came out beautiful. My lantern project was not the greatest the glue -up the glue-up was coming out of the top of the cardboard and the cardboard was off from the markings, however, my coaster's glue-up was wonderful and it did not take a long time to do. Both projects were wonderful, but my coaster project is the nicest one.

LED Stop Light

This is the LED blinking in a stop light form to make this code work First, we connected it to the board and got three black wires and 3 different color wires. On the board, we connected the black wires to GNDs, and the red wire was connected to GP14, the yellow wire was connected to GP13, and the green wire to GP11. Thus, connect the short end of the LED to the black wires and the long end of the LED to the different color wires. The code that we used is called code.py which was the code for the LED to go in a stop light that was 'Red LED to GP11 Amber LED to GP13 and Green LED to GP14, thus connecting the LED to the board but also coding of true, false, and time speed creating the stop light affect of having one go on and then one go off.

Variations of LED

Video_2.mov

Chase Clockwise

I first had to add new LED lights to my project, such as red2, green2, and blue LED, programming it to have 6 LEDs to make this one. I coded the green to stop and start and the rest follow in clockwise

Video_3.mov

Left Right

I coded this by doing green, amber, and red go on at the same time on the left side, then stop and let the red2, green2, and blue come on, coding a right and left pattern

Video_5.mov

Counter Clockwise

This is going in the reverse order, red2, amber, green2, red, blue and green making it counter clockwise

Video.mov

Blink All

This is where all of the LEDs blink on, and then they all blink off.

Up Down

This is up down, red2 and green turn on, then stop, amber and blue turn on and stop, green2 and red turn on.

Infinity Mirror Drawing and Prototype

Infinity Mirror

This is the propose drawing of the infity mirror the first layer is a wide piece then a narrow layer with a mirror with arclyic sheet on top of the glass then two wide pieces of cardboard then you glue your led's lights on the wide piece before the obleque on cardboard then pushes it together and then hot glue the last wide piece together. An infinity mirror creates the illusion of endless lights using two parallel mirrors and a light source. One mirror is fully reflective, while the other is partially transparent. Light bounces between them, fading with each reflection, which creates the appearance of a deep tunnel of lights, even though there’s only one light source

IMG_0259.MOV

Prototype

I made this mirror by first doing my first wide piece and hot glueing it to my narrow piece of card board then I put my card board with obleque in the middle of the narrow one then went to the top and hot glued the wide piece to the second narrow piece and filled the center with the arclyic glass part and hot glued my two wide pieces to the narrow one then stoped and hot glued my 6 less to my third wide piece then connected the last wide piece and created the infinity mirror

Final Infinity Mirror

Video of Infinity Mirror Working

First color

Second Color

Third Color

At the back of the infinity mirror is a mirror—technically, one of my cardboard hexagons with an opaque surface that reflects the light that hits it. In front of the mirror, on the stack of four wide cardboard hexagons, are NeoPixels, which are a luminous object that emits photons, the tiny particles of light.

In front of the lights is a reflective glass panel that is translucent, meaning it allows some light to pass through but also reflects some of it. When the photons from the light source travel through this glass, some pass through while others are reflected. The light that passes through reaches the back mirror and then bounces back, creating a reflection of light.

The beam of light that strikes a surface is called the incident ray. When it reflects off the surface, it becomes the reflected ray. This process repeats over and over again. With each bounce, a small portion of the light escapes through the translucent front, while the rest continues bouncing between the surfaces. This creates the illusion of many lights fading into the distance—an effect known as the infinity mirror.

Reflection Questions?

What was your favorite project from the school year and why?

My favorite project from the school year is the coaster project because I got to work with colorful wood such as purple heart/maple, and because my coasters came out cute. My mom loved her Christmas gift

What is something that you have learned in this class that you know well enough to teach another student?

Something I have learned from this class is that I can teach another student is how to work the laser cutter, and learning to navigate Onshape and gloforge.

What is one challenge that you have overcome this school year in Engineering Class?

One challenge I have overcome this school year in Engineering Class is believing in myself. At first, I used to ask for help right away without really trying on my own. I would rely on the teacher, but I realized I wasn’t truly learning that way. So, for the first time, I pushed myself to try things on my own. I ended up having so much fun learning how to code and building my projects. This experience taught me the importance of perseverance and the value of trial and error, both of which are key skills in engineering.
