Homework: Plush toy

Hello! This my final plush toy – Smile.

When turning on the switch, it looks in this way:

How I make this plush toy

  • Finish the sketch of the toy and the circuit
  • Choose the fabrics
  • (1) The fabric for the hair and eyes: black and very thick fabric to block the light
  • (2) The fabric for the face: flesh and thin fabric to let the light get through it
  • (3) The fabric for the mouth: Two different red fabrics
  • Cut the outline of the hair, face, eyes, and mouth
  • Add a thickness to both the hair and the face
  • Sew all the parts together! Hair-face-details
  • Finish the circuit
  • (1) Buy the electric materials: two red LEDs, one AA2 battery case
  • (2) Choose the resistors
  • Two 100 ohm – the light can get through the fabric and are not too dazzling
  • (3) Solder them together!
  • Place the circuit inside the face of the plush toy and adjust the position of the LEDs
  • Fill the face with cotton and close the face part
  • Finish!

Difficulty

hair

The most difficult part I met is to sew the hair together. The black fabric is too thick so I cannot use the sewing machine. At first, I sew the thickness part to the front piece and then to the back piece. When sewing it to the back together, I use two steps: at first start in the middle of it and sew one half side, and then the other side. And it becomes more and more difficult when getting close the side.

The circuit has two LEDs, two 100 ohm resistors and a battery case with a switch. I use paralleling to connect the two LEDs so they won’t be affected by each other.

The name and the story

His name is Smile. This is a simple name and he has a simple hope to bring happiness to others.

Smile comes from a comic book and travel to the world where we live. During his travel, he found that smile is contagious, which means when he smiles to other people, they often smile back even they don’t know each other really. It always makes him feel happy, and he hopes others to feel happy too.

Plush night brain

My plush is a brain! This brain lamp is for anyone who likes to use their brain, but also for those who want to take a break and keep calm. The switch allows you to turn on and off the light. It diffuses the light to help you relax or keel calm, carry on thinking about your next big idea! You can also pat it like your teddy bear when you need a break from thinking too much.

If your brain is constantly thinking, it is a reminder to stop working on your brain muscle but move your body muscle. Also, it is a reminder to think smart whenever you are working at your desk. It can be either put on your desk, your coffee table or hang from your ceiling of your front door.

I failed a lot in soldering but I learned so much about the best practices. I’m still learning about the circuit diagram and working with the resistors to make the light brighter. It also turned out blue or yellow LEDs are better than the white ones, which I thought would be good. Failing served good for me to learn!

This dipped plush light hangs on the wall and gives users a fun off-kilter light that evokes candy or cake.

 

The process began with laser cutting the holes in the top sheet then applying the fusible interfacing.

After applying the fusible interfacing I cut the fabric to size. I sewing with the piping and sewing it into place.

Following this I hand stitched the side piece into position to prepare it for the sewing machine.

The light box was made from an container for a pie. I used the lid from it and then spray painted it leaving holes that aligned with the holes on in the fabric.

The light box is elevated off of the base board with corrugated plastic sheeting and hot glued into place. The space between the outer fabric and the light box was taken up with batting.

I decided that this design required four LED’s. Here is the circuit diagram:

To achieve the candy coated appearance it was dipped into acrylic paint.

CLOUD CAGE

When I was a kid, I always love to see the cloud in the sky. I wanted to keep it in my room so I can touch it and play with it. I imagined the cloud is a child, loves to hover around the cage with its glowing body.

And then I bought the circuit for the coin battery from tinkersphere.

Sorry that I forgot we gotta record all the process, so I only took a few pictures.

Overall, I enjoyed the assignment a lot, and I love my little cloud cage!

 

Delicious Nightlight!

Hello, for our nightlight assignment, I made a donut nightlight! This is for the children who are scared of darkness. Children can use it whenever they have to move in the dark (going to restroom, etc) I chose the object that most children like to make them relate darkness to more positive feeling(sweet taste of donut).

The donut shape makes it easy for children to store the product. Children can hang it anywhere thanks to its hole. They can also carry it by their fingers and play with it by rotating it.

At first, I wanted to hang the donut on wrist, but in order to achieve that, size had to be too big. So I decided to make the real size donut.

Sewing the donut wasn’t the hard part. I bought thin fabrics for the led lights to be seen and attached the frosting and the donut.

I used tinkercad to figure out the circuit for my product. It was fun and also useful when finding the right resistor to use. In the tinkercad I used 3V battery but later I changed to 3XAAA battery. I used 4.5V battery and 100Ω resistor for this product. I decided to connect my leds in parallel because in that way, I can make sure other leds light up even one led has a problem.

The hard part was soldering and distributing the light. It was hard for me to solder three lines together since it kept falling off as I tried to solder the last one. Distributing the leds inside the donut was really hard. The donut was so small so it was hard to put 3 leds and all the lines inside.

I noticed that the donut has too many wrinkles on it after putting stuffings in it, so I had to detach it and made sprinkles instead.

There are several things I want to improve about this donut. If I have a chance, I would like to make it much bigger so that I can experiment more about distributing the leds and also want to use a little bit thicker fabric so that it has less wrinkles.

Finally, this is the picture of my happiest moment!
