For my resistive sensor project I hand sewed a puppet that contains a velostat bend sensor in its mouth and links to the LilyPad Arduino board, so that when it opens and closes its mouth it controls the pattern in which 3 LED lights light up on its body. My puppet also has hair on [...]
A glove that can be programmed to respond differently to touch can be wonderful for games. If you have ever played the game “Red Light, Green Light” you’ll know that having something visual during the game play can help the process go smoother and add another element of fun and creativity to the game. Similarly, [...]
For this week assignment I was experimenting with materials, trying to come up with my own resistor design. squishing sensor The first experiment was done with a balloon filled with salty water. According to the equation of resistivity in materials, I can change the geometry of an object and get a change in the resistivity [...]
Are you new to yoga? If so, do you ever wonder if you are actually doing the poses right? Well to help guide you a bit better, I have prototyped a yogamat that contains sensors to help tell you whether or not your weight is balanced. In order to make this, I first started by [...]
I used LEDs as rhinestones to make mittens sparkle in response to hand motions. Using velostat, I made a resistive sensor that senses how bent or flexed the wrist is. Incorporating the sensor into the natural bending motion of the wrist, more LEDs light up the more the wearer moves the wrist, capturing and amplifying [...]
Concept – The KNight Riders’ Glove My mode of transportation in Cambridge is the bicycle and I wanted to make something that I could use while riding. I designed a glove that riders can use as an indicator when turning (or more) when riding at night. The LEDs on my glove will **FLASH** when the [...]
MEASURING AND CALCULATING: Since the thread needs to carry at least 100mA of current to change the ink’s color and the battery is 3.7 volts, we know that the thread will need to have a resistance of 37 Ω (R = V/I). Using the multimeter to test the voltage and resistance: the voltage of the [...]
For the color changing assignment, I wanted to explore how thermochromatic ink can help reveal emotions. I first sketched some facial expressions that could be represented using threads. Then I used a paper box to represent the face. I then sew the facial feature onto the fabric and the box Here are the results: cold [...]
For this project, I added some computation to attempt to gain more precise control over the color changing qualities of the textile. I used several n-mosfets and a lilypad microcontroller to control varying sections of the circuit programmatically. A mosfet is a transistor that can be used for switching electronic signals- essentially a voltage controlled gate. [...]
I first tried to make a color changing sunrise, pictured below. It did not work well because the blue color changing paint was not dense enough to completely cover the orange and yellow sunrise. The thick blue layer also needs significantly more heat to disappear then the single Li-Po battery can supply so it only really works [...]
