DIY Gadgets - Page 4 by Julie One of the scariest health epidemics of my generation was HIV. I remember quite clearly its emergence on the scene, the graphic news footage of those first infected, people slowly dying from something so misunderstood and scary. It doesn’t seem to be big news anymore, but it’s still killing people all over the world. Well, OraSure, the company that brought us the first healthcare administered oral specimen HIV test available all the way back in 1994, have now developed OraQuick, a simple at-home test that allows people to test themselves in the privacy of their own homes for the virus that causes AIDS.

Connecting To The World with Danger Shield - ZachHoeken.com If you have an Arduino and a Danger Shield, and you are reading this page, you already have enough to start posting sensor readings to a webpage and sharing them with the world. You can also access those readings yourself, on the web, wherever you go. How? Controlling solenoids with arduino In this instructable we will be building a simple circuit that will allow us to control a solenoid using the popular physical computing platform arduino. I became interested in controlling solenoids for robotic music applications. A similar circuit can be used to control a motor or other devices that require more current than the arduino can provide directly from its output pins. Since the solenoid requires higher current than the arduino can provide we will be using an alternative power source for the solenoid (a couple batteries) and will be "driving" it with a TIP120 transistor.
SENSEable Shoes Created by Huaishu Peng and Yen-Chia Hsu at the Computational Design Lab at Carnegie Mellon comes the SENSEable shoes project. The shoes can identity and transmit information for 10 different gait patterns (standing, sitting, turning left, turning right, walking left, walking right, walking forward, walking backward, going upstairs, and downstairs). Suggested applications for the shoes include being used in gaming platforms (think Wii Fitness) or detecting abnormal gaits in health care patient monitoring. Project Description: "The goal of this project is to build a foot-computer interface: a newly hand-free and eye-free interactive technology designed for the growing pervasive computing environments.
ReadyMade Cool Copper Projects Warm metallic hues are easy to love but often pricey. When you create the look... Easy Doily Bowl Arduino Tutorial - Learn electronics and microcontrollers using Arduino! So, I get two or three emails a day, all basically asking the same thing: "Where can I learn about electronics?" In general, most of these people have seen some of my projects and want to be able to build similar things. Unfortunately, I have never been able to point them to a good site that really takes the reader through a solid introduction to microcontrollers and basic electronics.
inaluxe Yipe! more rain, wind and sunshine, good ol' nature just doesn't stop. After some 20 plus years of neglect (aside from the most pragmatically brutal trimming) the garden we inherited with our newish property has flourished after the first decent winter-spring and summer rains in close to 15 years. Playground - SolenoidTutorial You can not drive a solenoid directly from your Arduino. It requires more current than you can provide and produces destructive voltages when it is switched off. There is a simple solution. Solenoids take a lot of power
FabLabs Welcome to Fablabs.io! Here are few suggestions about how we can help you and how you can participate and talk with us if you have any question or problem regarding the Fablabs.io platform. Discuss with the community You can ask for support to the administrators and the whole community in the Fablabs.io Discuss section within the Site feedback category. Site feedback category we would also love to hear your ideas and suggestions regarding Fablabs.io, its features, development, how it works and how we can improve it. InterfacingWithSoftware You have come to the place to learn about connecting an Arduino to other devices, whatever software is running on those other devices. The Arduino can "talk", (transmit or receive data data) via a serial channel, so any other device with serial capabilities can communicate with an Arduino. It doesn't matter what program/programming language is driving the other device. You can either use the Arduino's "main" serial port, the one it uses when you "talk" to it to program it, or you can leave that channel dedicated to programming (and the development environment's serial monitor), and use two other pins for an extra serial link dedicated to the external device. Some programs (like Flash) don't have native serial capabilities. They can still communicate with Arduino through an intermediary which, like a "translator", enables them to talk to each other.
