In this week, I assembled every part together, thank god my soldering skill has improved a little bit in this process. This work turned out pretty close to my imagination, however, the Arduino board didn’t work well with it. I have the Tinkercad worked, the file transport is fine too, it’s just when I trying to connect the 5V and Ground the board directly turned dark, I haven’t figured what to do yet.

Pumpkin cape

Pumpkins are the first thing came into my mind when thinking of Halloween, that’s one of the reasons I have them as the major decoration of my cape. Besides, each time of this year when I walked into stores, there are all kinds of pumpkins in different scales with various facial emotion, however there are only few costumes using pumpkins as elements, then I decided to create my costume with pumpkin decorations.

Challenges were putting my complete circuit inside the costume and trying to hide them, I failed few times that my circuit broke and had to re-solder those weak connections. Even after solving this part, I struggled to organize all the wires together neat and clean. If I had to redo this project, I would definitely measure the length before building the circuit, so it’s easier for me to put everything inside the cape. Once everything is in place, it’s easy to wear the costume and I could simply touch the decoration on my shoulder to trigger the light changing effects (it’s just a little heavy on the left shoulder because the box itself and the Arduino board inside).

I achieved a great improvement in my soldering skills. What’s more, coding was tough for me when trying to achieve the lighting effects I want, I got several errors and before meeting with Becky for help. After the 1 on 1 meeting and playing with the code, I gained a more comprehend understanding of coding, and could be able to understand the meaning of the codes.

Halloween Hat Project – Anne

Description

This project is organized around the character of the Sorting Hat from the first of the Harry Potter books and movies. The intent of the project is to amuse people and invoke nostalgia for those who have read the books. The hat can be worn. The light effects are controlled by two sets of button switches hidden in the tassels. I learned a lot doing this project including soldering in tight spaces–the neopixel jewels and soldering header pins in particular. The neopixels and sound board were all new to me as well. The project was more work than I anticipated and I don’t regret the time spent on it as I learned lots of new techniques. However, the scale of the project and the time to execute it were a real challenge. For the next iteration I would focus on reducing the footprint of the Uno to a smaller board to fit inside the hat and exploring the neopixel code for more effects. Additionally, the button switches are “clicks” and that combined with low volume on the hat’s “voice” needs more work.

WarioWare Crew Member – Margarita’s Halloween Costume

I made these sunglasses after looking through inspiration photos of bedazzled sunglasses and realizing that it would be cool to have the lenses work as a backdrop and a diffuser for the LED feature. My initial idea was that the glasses would serve as “Seeing Fireworks” glasses and that was the basis for my costume. Upon pulling the outfit together, I found my husband’s scooter helmet and combined the helmet with the glasses, which made him think of WarioWare. So, I decided to rebrand my costume into “if I was a WarioWare crewmember what would I look like”.

The glasses are put on underneath the helmet and are connected to a tilt ball sensor that is worked manually off to the side to change the fireworks display. It’s not the most comfortable pair of glasses to wear as the wires I have are not long enough when I connect to the uno. So, I had to create this structure near me to hide the uno and hide my shaking the tilt sensor manually. Originally, I wanted to create the glasses with the GEMMA so I would not have to be connected to the uno and could turn the glasses on with the tilt sensor connected to the frames. However, I realized too late that I bought the GEMMA with the microUSB and I don’t have the connection for that so I decided to use the uno. The code was definitely tricky for me as well and thanks to my classmates and Becky I was able to get a lot of help so thank you all for that!

If I were to remake this costume, I would definitely make sure that I had all of the proper equipment from the get go including longer wires. I would also think more about the ‘story’ of my costume from the beginning so I could incorporate more elements ahead of time to help hide the wiring.

Technicolor Fly – Stephen’s Halloween Costume

I wanted to make this costume, because I thought that this was a very funny moment in the VP Debate. I am very interested in politics and watch all of the debates. This country is at a pivotal moment and there is so much scary news centered around the election today. So I just wanted to make fun of Pence and this horrible administration with this idea. This costume is really just supposed to be funny and not very serious.

I put two neopixel rings in the center of bug eye glasses that I found online. The wires run along the left side of the glasses frame and down to the Arduino board. While finishing up the soldering, some of the tinning wire dripped down and hit one of the lights and burnt it out. The code was written so that the whole ring would light up, but I didn’t have the time to reorder and resolder.

If I were to do this project over again, I think I would be more ambitious and include more lights. I bought the glasses in a six pack since it was cheaper than getting just one. I think it would have been cool to have a 12 eyed mutated bug with 12 neopixel rings. I thought about doing that but the price of the rings deterred me. But overall this was a fun project for me. Halloween has never been a favorite holiday for me, so it was really nice for me to learn a new skill while making something that I found funny.

Zekun’s Halloween Costume

I want to design such a headpiece because I want to find a way to include my night light as a part of my Halloween costume. Therefore, I decided to make this headpiece for psychics. The LEDs on the headpiece is gradually shifting from pink to green to match my crystal ball’s iridescence. And the NeoPiexl Jewel have a rainbow-color gradient.

One thing I would do differently if I had to do it again is that I will change the color of the NeoPixel Jewel. The color of the NeoPixel Jewel and that of the pixels are not matching very well and can be improved.

Flow——Yiwu’s Halloween Costume

At the beginning, I wanted to imitate the flow of light. After making it finally, I have to admit that there are actually tapes everywhere inside. I used a light strip close to 3.5m, which made it almost impossible for me to sew it.

In the process, I learned that I need to make reasonable use of the functions that have been written. Don’t reinvent the wheel. At the same time, I especially enjoy this process. I haven’t written a program for a long time.

Compared to humans, the program is cute. Yes is yes and no is no. If I can do it again, I will definitely not buy such thick clothes. There is no light at all. I can only stick the light strip on the outside and then cover it with a layer of black cloth.

This is the first time I successfully lit up on the board
This is the first test after porting the code to a longer LED strip. Just modify the light flow speed/color change speed/number of bulbs.
This is a comparison of my own rewritten code. Before it could only have a moving light spot. After I rewrote the code, it can have 2 light spots that move at the same time. This is very helpful for my future design. Because I connected the control input of the light strip from beginning to end. So I can’t just have a moving light spot.
This is a test after connecting the new part. In fact, I soldered a meter of light strip to the back. But then it had a bug that I couldn’t understand. I know it may be related to the upper current limit of the arduino driver board. So I used a 12v battery. But in the process of step-down, I think it affects a certain waveform of the current. The flash pattern of the light strip after the battery is finally connected is completely incomprehensible. So I can only reduce the number of light strips from 5 to 3 in order to use arduino for power supply.

MoodCloak – Isabell’s Halloween Costume

The Story:

This is going to be a mood cloak for vampires only. This cloak will be able to detect vampire’s mood. Just like a mood ring, it is going to change colors according to the mood of the vampire who wears it. The colors will be:

Red = Happy, I’ll conversate

Blue = Angry.

Green = Thirsty, Don’t Bother Me

Purple = Feeling Nice Today

All sorts of colors = Sleepy, bye

This cape is for vampires and vampire’s friends who cannot tell their expression in their faces. The mood will be able to help friends and also help the vampire understand their emotions. We all know vampires are emotionless and maybe sometimes as vampires’ friends, we need to understand their mood so we will not get eaten.

Process:

What I learned through this process is that the story of the product matters. When you put in the meaning of the product, it brings the product to life. A struggle I came across was working through Arduino Code but it was my first time but I think after experimenting it has worked out! I also think my soldering skills are improving day by day.

Sleepy Vampire

Qiting’s Halloween costume

Final outcome

Design concept

This is a vampire bride costume that I designed for Halloween. I made a black wedding veil(hair pieces) and dressed it with 1o led randomly. Also,  I wanted it to light up when it was shaken slightly, but it failed after testing with a vibration switch.

Materials

  1. Led strip(ws2812b)
  2. Vibration sensor switches(For testing)
  3. Two fabric materials to make a black wedding veil(hair pieces)
  4. A hairpin
  5. A ghost toy decoration
  6. Black wire
  7. Hot glue
  8. Sewing kit

Making process

Step 1: I made a hair piece of black wedding veil by using two different fabric and a hairpin.

Step 2: Cut 10 leds from the Neopixel strip and solder them one by one. Each led was tested once to ensure that there will be no improper connection problems.

Step 3: Glue the leds to the headwear with hot glue. I tested the vibration switch and found out that the vibration switch doesn’t work pretty well. The switch cannot detect the head slightly wobbling sensitively. It only work when shaking head wildly. So I removed the switch.
