As a Water Quality professional working in the drinking water field, I know how important it is to accurately monitor the disinfectant levels in the drinking water that gets served to the public. Usually, that means taking weekly grab samples in the distribution system and measuring free chlorine or total chlorine residual via a DPD […]

Create a pressure sensor using: – Needle-felted wool – Thin muslin – Velostat – Conductive thread This sensor can be used an analog input for Arduino code. Step 1: Prepare the Core Components Component 1: A felted wool ball. This can be made using unwoven wool (I used Leicester wool), a felting needle, and a

The yoga breathalyzer is a breath visualization tool to help you understand and get in touch with your breathing. Breath is the basis of yoga and meditation, and this biofeedback tool is one way to develop a deeper understanding of your own breath. Using Arduino, a headset-mounted wind sensor, and an LED strip, it’s simple
As a follow up to the Arduino Audio Input tutorial that I posted last week, I wrote a sketch which analyzes a signal coming into the Arduino’s analog input and determines the frequency. The code uses a sampling rate of 38.5kHz and is generalized for arbitrary waveshapes. I’ve also turned the LED attached to pin

This project shows how to make an interactive picture of a dandelion. It starts as a yellow flower with LED’s for petals then changes into a white dandelion clock, which can be blown on to make the seeds disperse. It is based on a beautiful artwork by Qi Jie, whose picture was inspired by a

I recently had my kitchen updated and knew that lighting would ‘lift’ the look of the cupboards. I went for ‘True Handless’ so I have a gap under the work surface, as well as a kickboard, under cupboard and on the top of the cupboards available and wanted to light them up. After looking around

The problem we picked was – Growing plants in limited space by amateurs. Many people would like to grow plants (basic vegetables, herbs for the kitchen, etc) but do not have enough space in their house to do so. They also may not have the expertise to grow plants, so would need an easy DIY

The project conducted as part of the Computational Design and Digital Fabrication seminar in the ITECH masters program. https://icd.uni-stuttgart.de The Idea Exam period is coming. And you already feel sleepless and hopeless. You want to study, but you’ve lost your motivation. And it’s crucial that you study hard. But the weather outside is perfect, it’s sunny.
This is a trap to capture the mice without hurting them, so you can release them outside. If the proximity sensor detects the mouse, the Servo motor will close the door. You will receive an instant message and/or an Email, to inform you that you captured a mouse. When you are not at home or

This project is a continuation and reimagining of my former colleague’s (metaterra) “Whisker Sensory Extension Wearable”. The purpose of this project was to focus on the creation of novel, computationally-enriched “sensory extensions” that allow for augmented-sensing of the natural world. My major effort with this project was devoted to the fabrication and implementation of sensory
