Cheryl’s Halloween Costume

My halloween costume is inspired by chinese culture, especially assassin from some shows that I’ve watched. For my main costume, I’ll be ordering a Qipao dress, sai props, and maybe some hair accessories.

For this project, I will be making a mask inspired by Peking opera, the four main roles are Sheng, Dan, Jing, and Chou, the color usually represents the roles, and they are categorized based on the gender, age, evil or kind-hearted nature.

I will be making a white mask(usually the bad guy role).

I couldnt find any white mask that is hard enough, most of them on amazon are made out of either thin plastic or paper. So I am thinking of making the base with sculpey and paint directly on it. Instead of a mask to wear on the face, i’ll be adding a longer strap to carry it on my back.

Cheryl’s Plush Night Light

This little plush toy is for kids who are afraid of dark. The little dino is a perfect toy for kids to cuddle with in the dark. The wings is bright enough to give kids comfort and a sense of companionship in night time, while the LED brightness is not over exposed to the point of discomfort for kids. I really enjoyed the sewing process and I think one of the most challenging part was soldering the LED.

For the little dino’s head, I sewed yarn between the two head pieces to emphasize the spikes.

I chose to make the wings with light muslin fabric so that its thin enough for the light to diffuse through.

Next I sewed the body, wings, and head together.

I did not sew the wings entirely, I left a slit that is wide enough for the LED to go through.

I hand sewed the legs and arms onto the little dino’s body.


Cheryl’s Plush Night Light Proposal

These are some sketches of flower and moon shape bed for dogs. For the flower bed, LED lights would be in the bees where they will be stabilized with wires. For the Saturn and moon shape bed, LED light would be in white or yellow, depicting stars.

I am now leaning toward this direction. LED Dinosaurs lamp for kids who are afraid of dark!! I am thinking of using polar fleece as the main fabric, and the LED lights will be the dinosaur’s eyes and nose. Maybe some LED on the wings too.

Logitech Mouse Teardown

Tools I used: 

  • 8-in-1 Precision Slotted and Philips Screwdriver
  • A single driver
  • 4 double-sided bits include #000, #00, #0 and #1 Philips tips and 1/16 in., 5/64 in., 3/32 in. and 1/8 in. slotted tips

It’s my first time fully tearing down a mouse and the result surprised me. I have not imagined before how many components/parts can go into one fist-sized mouse after laying them all out on a flat table. For example, just the internal body part consists of 22 screws, which is more than some furniture that I have built. During my teardown process, I also realized how some parts are specifically made to be more adhesive and difficult to dissemable.

For example, I was stuck at the very first step, trying to figure out how to get into the inner parts of the mouse. Then I found out that the screws were all hidden under the nylon feet with adhesive materials under the mouse. I am impressed at how the mouse included the nylon feet to cover the screws to make the design as a whole look seamless while providing a smooth surface to support the mouse to better sense the movement.

Some other difficulties I came across was taking apart the scroll wheel that was fixed with a spring and a few plastic pieces that helps stabilizing it while scrolling. Taking apart the scroll required the help of a second person. Also, the metallic piece located on the left side of the mouse that lets the finger rest was tightly attached to the main surface with adhesive, so I tried using a screwdriver to pry it open with force, but I ended up breaking it into two pieces.

After unscrewing all the tiny screws located below the exterior body parts from the mouse, there are many little round “buttons” that lock the three main body parts together. I inserted the screwdriver into the slit between the body parts, and tried lifting it from one side first and as the gap in between gets bigger, I break apart the body parts like how I would open a crab.

The first part of the mouse that I like is the OMRON D2FC-F-7N switch which serves as the mouse’s right and left clicks. How it functions is that there’s a leaf spring under the microswitch that reflexes when we hit on them and it only works when the leaf spring is placed at the very bottom notch of the microswitch. A click will send electrical signals via metallic contact to the computer. This is the core of a mouse and always wanted to know how it responds when interactions occur. 

The second component of the mouse that I found interesting was the Atmega324PA microcontroller. This is the microchip that enables the mouse to run. It is incredible to see how a finger-sized chip can store so much data and information to make a mouse functional. For example, this microchip alone has “32 KB ISP Flash memory with read-while-write capabilities, 1 KB EEPROM, 2 KB SRAM, 32 general purpose I/O lines, 32 general purpose working registers, a real-time counter, three flexible timer/counters with compare modes and PWM and many more.” And this microchip operates in a single clock cycle that delivers specific instructions throughout to balance the power consumption and the processing speed.

Cheryl Zhang

I was born in Vancouver but grew up in Beijing, China. I completed my undergraduate studies at Parsons School of Design with a major in communication design in spring of 2021. In my prior designs, I focused mostly on branding, editorial design, and typography. Thus, many of my works revolved around food packaging, restaurant rebranding, and book designs. Now I hope to become a multidisciplinary artist and mixed media designer who can transform complex ideas and information into interactive visuals through all mediums. What I am most looking forward to in this course is the opportunity to gain hands-on experience in the craft of designing and creating things by hand rather than digitally like I have been doing in my undergraduate. 

In my free time, I am always on my hunt for the next popular food or activities in town. I love eating and trying out all different kinds of cuisines. I am also an outdoor person who really enjoys nature, so I would often go hiking with my dogs.
