So my last project was a Arduino wind chill machine. http://www.instructables.com/id/Arduino-Wind-Chill-Machine/ Naturally, this Lazy Old Geek wanted to add a weather vane (wind direction) to my weather station. Who cares, you may ask? Well, I am a Geek. Actually, wind direction has some importance. Here in the high desert, the winds are usually from the …
A simple and elegant way to help keep your personal space bubble from being invaded by close talkers and overly huggie people. This is a stolen or borrowed idea from Phillip Torrone of Adafruit, who mused about something like this on an episode of Adafruit’s “Ask an Engineer.” I decided to incorporate this idea …
This is the high-tech version of hanging a tennis ball from the ceiling from a piece of string. Of course, if you have two different types of vehicles, that tennis ball isn’t going to land in the same place on both of them. This project can prevent hundreds of dollars in dry-wall repair and bicycle …
This piano-liked thing is what I called touch sticky note. I Use a piece of sponge as the paper, and put 8 x 8 LEDs under the sponge. Whenever I touch the touch screen, the related LED will turn on, and this is how I write for the sponge. I got the idea from the …
Has this ever happened to you? You wake up in the morning and realize that you’re terribly late for work/class/your weekly pedicure/whatever. You throw on a t-shirt and flip flops, sprint around your warm, heated house grabbing your belongings, and race out the door…where you suddenly find yourself surrounded by a cold, biting wind encompassing …
A bracelet decorated with six conductive fabric petals and a thread of beads with a metal bead at the end, makes for a simple six point tilt detection. It is also designed so that the metal bead will make contact with two petals if it lies in between. and then of course it will make …
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 …
