Motion Glass



In this project, I used PIR (A passive infrared sensor) motion sensor to calculate your shower time. This is connected to an Arduino Wifi board that is inside of a clear acrylic case. The duration of your shower will be measured based on your motion and the shower record will be stored and notify you through your email/SMS/twitter account through the I have chosen to use SMS as my report method, but I can utilize many other options like. Instead of an Arduino Uno, I only used Arduino Wifi board called, adafruit HUZZAH ESP8266, to fit and run every component in this motion glass.

For this project, I had to set up the sequence to activate the timer and send the information to myself to remind me that I should save water by taking a shorter shower!

Project Proposal: Who did we pass by w/ Wireless Arduino​



There’s an old saying in Buddism that even brushing past a person is one’s karma.

My final project will be on our daily interactions with strangers. Using a near-field communication (NFC) sensor or a radio frequency identification (RFID) sensor, I want to create a device that keeps track of people I passed by unconsciously. Though the premise of this idea is that everyone has this device, I find this interaction very interesting.



  1. Build a 2″x 2″ device that interacts with another device.
  2. Make a 6″x 6″ box that lights up (green or red).
  3. Put the Bluetooth or NFC sensor inside of the device.
  4. Before you go to bed, you will be able to see the list of people who passed by throughout the day.


Draft parts and tools list


Functions I wish to explore

  • IoT
  • The unconscious human interaction



Homework for Next Week

  1. Play with the RGBWstrandtest code for your NeoPixels and make a video of your animation.
  2. From your Arduino kit booklet, complete Potentiometer exercise Circ-08, DC motor exercise Circ-03, and make videos of each.
  3. Create a blog post with all three of your videos embedded (hosted on instagram, youtube, vimeo, etc., NOT uploaded directly to blog)
  4. Parts research for innovative switch project and order parts, email Becky for help figuring out which parts could be used for your switch ideas.
  5. Make a blog post about your innovative switch ideas with sketches

*Don’t forget to post them by Wednesday 8pm and put them in a right category (“Arduino” and “Works in Progress”)

The Sun (Plushie Prototype Part 1)

For my plushie prototype, I wanted to make something that could be a decoration for my home. Even though I moved to my apartment a month ago, I still find it not as comfortable as my room back in South Korea. So, I decided to make a plushie light that can reveal a bit of my personality. I was first inspired by the Richard Clarkson who made the Cloud, and I was interested in making light-up cushions that would represent our solar system. Therefore, I started to make my first prototype of “the Sun”


KakaoTalk_Photo_2016-10-05-18-28-07_40.jpegI bought this three-quarter yard of nice and soft plushy materials for 13 dollars. Since this was just my first prototype, I did not want to make it too big.



Then, I googled sphere sewing patterns, and Multi-segment construction style looked pretty awesome to me.

KakaoTalk_Photo_2016-10-05-18-27-59_93.jpegI made a 4inch X 7inch eye-shape pattern with white pape, and I traced the shape.


KakaoTalk_Photo_2016-10-05-18-27-55_59.jpegThen, I cut 6 of the same pattern with Kevin’s nice scissor!


KakaoTalk_Photo_2016-10-05-18-27-54_4.jpegNow it is time for me to stitch them together!


KakaoTalk_Photo_2016-10-05-18-27-46_76.jpegMore sewing!


KakaoTalk_Photo_2016-10-05-18-27-41_81.jpegAs you can see from this picture, I had so much fun sewing it by hand! But, for the next prototype, I am definitely learning how to use a sewing machine!


KakaoTalk_Photo_2016-10-05-18-27-30_18.jpegI flipped inside-out and stuffed with supreme fiber fill! …somehow it looked more like a pumpkin or a tomato, not the Sun. I should try to make a different pattern to make sphere.

..KakaoTalk_Photo_2016-10-05-18-27-25_91.jpegThen, I went to a store called Thinksphere to buy things that I wanted to play around with. I bought a battery pack and white LED bulb and etc. (I even bought a Bluetooth module just because it sounded so cool.)


KakaoTalk_Photo_2016-10-05-18-27-20_14.jpegI made a simple circuit diagram! Then, I put the circuit into my sun plushy.


KakaoTalk_Photo_2016-10-05-19-31-48_77.jpegOh man. Where did my sun go? I am seeing Halloween pumpkin right there. The white stuff next to the sun should look like a cloud… oh well, I should put more LED lights and try different materials for the surface. I’d better start to work on the next prototype now.


Sun Plushie Prototype – Circuit Diagram

For my plushie prototype, I am trying to make a soft sunlight plushie. I bought two red 10mm LEDs and one white light bulb style LED to make this prototype.

The circuit diagram will be using the battery packs and followings:

  • Triple AAA batteries at 1.5V each will sum up and have a power of 4.5V
  • 1 x white light bulb LED + 2 x red LEDs
  • 1 x 27-ohm resistors for white and red LEDs 


Mickey White


Mickey White is a laboratory mouse that born and raised in New York University’s Center for Genomics and Systems Biology. When he realized that he will be tested by scientists soon or later, Mickey White successfully escaped from the lab. Wandering around the city, he found people making cool stuff in SVA Visual Future Lab and sneaked in there. But, I caught him. His cheek is so fluffy.
