Battle Painters 2.0

Bildschirmfoto 2014-06-28 um 17.15.57

In week 7 of the course we had a mini workshop in visual programming. I was curious about Processing and the possibilities in combining physical interfaces with on-screen visuals. When I was young I loved the game Battle painters. It allows you and your friends to play against each other on the same keyboard of […]

Recap: Thumb Wars

IMG_4203

In week 4 of the course I came up with the concept of “Thumb Wars. The idea is that while playing Thumb Wrestling, each player puts on one glove first. This smart glove has conductives sowed into it, so that certain postitions of the two hands close a circuit, the same way a button works. […]

Final Project: 3rd update

Getting the Code right I spent a full day trying to synchronise the motion sensor and the sounds. This mainly meant trying to understand the example code for the MP3 shield, to figure out how to adjust it for my purposes. This was difficult because some commands and syntax were hard for me to understand. […]

Final Project: 2nd Update

I’ve started reading a lot about tracking motion, about playing sound files on Arduino and about similar projects. Here are some excerpts of my Work-in-Progress. Hardware Input: For detecting motion I started working with a PIR motion sensor (Noel has done a good description on it here). PIR stands for passive infrared. After calibrating in […]

Final Projekt: 1st Update

I have chosen to change projects. The bike light was an interesting idea – But rather then starting an all new project, I decided to complete an existing one. “Cycle Pole” is a public design concept I developped about a year year ago. ——————- What it’s for: Accidents between cyclists and pedestrians are a much […]

Main Project

Bender is an interactive bike light, that helps keeping you safe at night. The product is worn on the upper sleeve. It combines the functions of a back light and a turning signal. Bender is a snap bracelet. It’s light and easy to apply. The light is emitted byred and yellow Electroluminiscent (EL-) surfaces. They […]

Animating an LED matrix

IMG_4439

We built a 7×7 LED matrix that can be controlled by Charlieplexing, a form of multiplexing. 49 LEDs can be adressed seperately while only using ten pins. Our initial idea was to use the matrix to play animations, kind of like a low-resolution display. We also thaught about ways to translate an input of a […]
