Yiwu’s Hallowenn custom

This dress is a cloak. At the beginning, I wanted to catch the light. Because light will slow down in special materials. I think we can have a material that can slow the flow of light so that the human eye can see it?
In the end I found it impossible, at least for now. So I want to use leds to simulate the flow of light. Then put it in the clothes.
After this idea was formed, because I had referenced the code of the project I was wearing on my head, the code of this project did not seem to change. I thought about how to change it. So I decided to add a sensor. Let it make some changes. Finally, I decided to use a sound sensor to change the light state according to the size of the external sound.

I used the RGBW light strip and sound detection module. I also bought a super large battery.

As for the Arduino technique(s) I’m using, I will combine the light drop and rainbow in the Arduino code.

Yiwu’s Neopixel Circuit and Halloween Costume Brainstorming

I don’t have white color on that board. So it’s not running in the right way.

Then I checked to code to understand how it works.

After doing this, I created my Halloween Costume Brainstorming. I was inspired by cyber wig and wanted to make something that also allows light to flow. I will make it into a dress. In this way, the room for improvement in the later stage will be larger.

At the same time, I hope it can have some interactive functions with the environment if possible. So I also reserved space and routes for adding sound controllers in the future.

I also wrote them logic of coding.

Yiwu’s plush night light

This night light comes from meat bone toys. I choose this because it has four angles so I can put four lights inside. I intended to make some hand toys but they were not suitable for the requirment. This is used to make people feel relaxed. Although it’s a little bit tricky, I think the user will love this little cutie no matter how I design it. After all I made this.

Things used: cardboard, brown fabric, ping-pong ball, lights, Foam

This is the start of sewing. I tried to make it meticulous.

I used the foam to diffuse the light, since I bought the wrong blue lights which has a very strong directivity.

Also I used ping-pong balls to make light more gentle.

I found the most challenging part to be the sewing part. I sew twice to make it clear because at the first time I sew I didn’t do it perfectly. So I have to cover it up after done. If I had more time I would sew more carefully from the beginning.

Description of my night light’s story and the target user

This is for my girlfriend. A few days ago I told her this project. She always likes soft toys since I remember. So next week I’m going to redo a soft hand toy. This is a test of the process and the light color. I think purple is so ideal when done.

Description of the parts and materials I plan to use

I’m using pp cotton. It’s soft and light. Aslo with a unparalleled penetrability for lights.

The material used in prototype was from old clothes. Very thin. I plan to use a thicker one since it would provide a better shape outside.

Old Cellphone Teardown

Video

This is an old cellphone made by a local small company in China more Than 12 years ago. It’ has a slide cover which was quite fashionable at that time. And this added function also made it more complicated in form compared with normal cellphones. For safety concerned the battery is removed and won’t be showed in the teardown process.

The design elements I found

Before I teardown this cellphone I thought it should have a more conposed inside. But it turned to be a product between a simple combined device and a highly customized cellphone that we see today. It makes great sense as the age of personal devices were just about to start at the time it was developed. It’s a slide phone and the sliding mechanism inside is very small but smart. The designer used only two flat springs to enable the movement. It all happened in a sheet of metal with a thickness less than 2 mm. This is a good example of how technology could help improving the final outcome of products and even made something impossible become real. Another thing I found was when I tried to tear it down, there were two screws that were half covered by other parts. I was trapped by these two for a couple of minutes until I realized the designer was somehow telling me these two screws were not to be removed at that disassembling stage. Then I sure found another two hidden screws that works. This reminds me of some things I learned called Design for Assembling. We once visited the factory of Daikin and the manager told us they use different colors and shapes(Square, circle, triangle) for plugs to make it impossible for workers to assemble them in wrong ways. This should be Design for teardown but sure is also something we designers could help people to avoid a lot of problems.

Hi, I’m Yiwu Yang

Hi, I’m Yiwu from Chengdu, China.

Before Pod I was taking college at SJTU, shanghai. I majored in mechinery and power, focused on new energy.During college I made some electronic components included objects, such as Magnetic levitation table lamp, mixed beverage self-service machine, barbecue machine without power supply. Some of them were Arduino based.

I like making Gundam models. Although this hobby was interrupted few years ago because of the lack of condition, I still enjoy making things by hands and hope oneday I can pick them up again.

I’m looking forward to make some cool stuff in this course. Here are some projects I made. Hope you like it:)
