This caterpillar night light is for children. I modeled it on the shape of a neck roll pillow. It is for when a child wakes up in the middle of the night. It is soft and big enough that it can double as a small pillow and does not take fine motor skills to turn it on. The light is meant to be soft enough to not disturb any other sleepers.
It was an interesting challenge to work with the light as well as the plush negative or light knock-out stripes.
This is the pattern:
In progress images and first circuit. The circuit was modified to include two more LED’s for the antennae:
Here is the circuit diagram:
Building the circuit and diffusing the light was challenging. The ping pong balls helped amplify the light and the tubing helped work the light into the antennae.
The materials for the plush night light include:
- muslin and plush
- ping pong balls
- 2 pipe cleaners
- 6 ping pong balls
- 10 LEDs
- 10 100Ω resistors
- battery pack
- 3 AAA batteries
Here is the first prototype:
Here are the early brainstorming sketches:
This night light is designed for people who needs a little bit of light source in the middle of the night. it’s inspired from moonlight in the darkness and created as a moon-shaped object. The light could be either hang on the wall or placed on a closet as a light source. It contains three yellow LEDs to produce proper amount of warm light to enable people walking around or simply as a reading lamp. The use of yellow light also provides comfort than a normal white light, I’ve got night light producing white light before, and I felt it’s somehow uncomfortable seeing such bright light source in the darkness. However, warm yellow light would reduce this problem and improve one’s experience at night. My intention was to create a product that makes the user feel meaning and warm.
Materials and parts used:
I used my old bedsheet as the material to create my night light, and filled with cotton. For my first prototype, I made the moon shape too skinny and thought it might be hard to sustain after filling with cotton and LEDs, so I made another moon which is more “rounded”. In addition, I was planning to contain five LEDs instead of three, then I realized it might be too much after testing out.
While building the circuit, at first the wire was too short to separate LEDs apart in the moon-shaped object, so I measured the distance between each LED and rebuild the circuit. Another challenge I discovered was the method to hide wires and battery case within the design. I haven’t figured out a way yet, but I thought maybe a base connected to the light could work.
These are my three initial ideas. The first idea is a floating balloon lamp, the second one in the shape of a coin purse that lights up as soon as you turn on the light, and the last one is to change the light effect through the texture of the fabric.

My intention in designing this night light is to create a warm atmosphere for users by changing the lighting effects. It can be designed as a series of night lights of different sizes and placed on the bedside, desk, living room, etc. according to the needs of users.
Cloth is a material with a certain degree of flexibility, which can change the lighting effect through some simple fabric modification. I made diamond-shaped folds by sewing. When the fabric is stretched, the folds are deformed and the light will be different.
I first tried to make diamond folds on the black fabric to make a small model, but I finally found that the dark fabric did not transmit light, which failed.
Then I used white cloth to make a larger one. The diamond-shaped folds give it a certain degree of elasticity, and the light will change when the folds are deformed. Since the fabric is very soft and can’t support the feature, I used cardboard to support it.
The final model replaced the cardboard with anti-collision foam, which can transmit light and have a certain degree of support.

After prototyping, I have decided to change the design of my plush night light from bear to rabbit shaped. I wanted to use the paisley design to be part of the clothes rather than the entire fabric. I felt like this would have completed the doll and brought balance. Therefore, I strategized again how to create this bunny.
The user target is for users who keep up to fashion trends and may want a fashionable doll but may not have enough money to invest in an expensive high-end item. This will be a DIY kit that keeps up to trends in patterns and design that can be made at home! The colors, patterns, and shape will be updated to the upcoming trend. The paisley print is up to date on fashion trends now and so are pearls. The colors used is for stress relieving color which is blue but classic blue is also 2020 Pantone color. Anyone who desires a fashionable item may feel trendy and also easy for the eye to see with the color that brings relief. This doll can be for younger kids or of any age that are trendy and may want a fashionable object that is affordable.
Here is the circuit board that I created. This took pliers, wires, soldering materials, LEDs, battery pack, and AAA batteries.
I would say the challenges of this journey was to make this product as fashionable as possible but easy to follow along. The bear in the beginning after trial and error seemed not balanced enough to be presented. After a lot of thinking and changing the design of the animal and only using the paisly pattern on the ears and the clothes it felt more complete. What surprised me was that it turned out way more complete than I thought so changing up my design and strategy was a good idea. That is the beauty of prototyping. The challenge was to finding the circuit board however the product is too small and the battery pack was too big so there was nothing that could be done unless I tape the battery pack to the back but I did not want to do that.
This plushie is intended for all ages and will be retrofitted as a mobile in the future. I used felt, polyfill filling, and cotton fabric. In the previous prototype, I used felt for the orange sunrays, but found it harder to connect to the yellow fabric with hidden seams. Opting for orange instead, I used fabric glue for this portion and for the facial features. I also added a middle panel on the sun so that the rays did not become distorted with the polyfill. For this project, I used three white led lights attached to a battery pack. In the future, I would probably use 1 or 2 more lights in yellow. Alongside the lights, I believe adding a push button to the wiring so that a switch is more accessible.
This push night light was made in the shape of a crystal ball. I choose to make such a night light because I thought it would be fun to see how a crystal ball light up, and to see how light diffuse inside that ball. I want this night light to bring its user a feeling of mystery.
For material, I used iridescent chiffon and a piece of grey fabric. I also used chiffon in the inside of the ball. I used poly-fill to fill the inside of the base. Four LEDs were used in it with a 3.7V Li-battery.
During making this night light, I tried different filling material and find out that chiffon itself works the best in delivering the mysterious feeling I want. During making, I found that it is tough to saw a perfect ball, and using chiffon made it more challenging as it is very easy to ladder. If I had more time to work on this project, I would make that ball again.
This nightlight is intended for all ages and groups of people. The following items were used to create this light: 6 blue LEDs, 6 resistors, wire, battery holder with switch, poly fill, mesh fabric, woven light blue fabric, sewing needle and white thread.

Making process is as seen above. For better reference, I asked my friend who has sewn her whole life to show me how to use the sewing machine. It was an epic fail. I also tried to use ping pong balls to propagate the light, and that also didn’t work for me. Below please see my friend’s prototype.
Overall it was a lot of the same from the first prototype. I tried to use the ping pong balls, as mentioned, and it just didn’t do me any good. I also noticed that the less poly filling I used, the better it made my product look. I used a mesh fabric to wrap all the lights inside it, and then I inserted the mesh fabric with the lights in the middle of the material. I then lightly filled the rest of the inside with enough poly to hold my pattern shape up, but not too much, so it would not block the light.
My target user is a child between the ages of 5 and 15. The idea for my plush night light is to make interactive toys that resemble common fruits and vegetables but with totally wacky and unique colors. For this example, I made an avocado that is teal with a pit also in teal. Further designs will have multiple lights that twinkle and flash on and off in a way that mimics starlight. I wanted to make a night light that aided children in falling asleep but didn’t explicitly tie back to a more traditional form of clouds, stars, and the moon.
For this prototype, I used two similar colors of light fleece fabric, teal thread, foam beads, a ping pong ball, as well as two green LED lights, wires, 220 ohm resistors, heat wrap tubing, three AAA batteries, a battery pack.
In my initial prototype, I made the drawing for my avocado to be way too small. And I made the mistake of making it the exact size that I wanted the toy. After sewing, the top was way too pointy and it just looked off. So for this, I went and got a yard of fabric and made the toy much larger. This was a really fun assignment and it definitely made me think of toy construction in a different way.
If I had more time to work on this project, I would improve the sewing. Closing the toy proved difficult for me and it’s sloppier than I would have liked. Also, I would push the toy to be more dynamic of a shape.
