This kit is designed for physics experiments at the middle school and high school levels. These sensors aren't just black boxes - they're easy to inspect, modify, and repair. This kit includes the following items: force sensor pulley rotation sensor laser gate sonar accelerometer compass This documentation assumes that you've already installed the WireGarden browser plugin. If you
As a fanatical gardener or a professional farmer, knowing the environmental conditions of our soil is invaluable. Obviously, we can't measure the number of worms or pieces of organic humus, but we can measure temperature and moisture content really easily.This is not a difficult project and what you end up with is a very swanky looking bit of kit that will impress most people until you put it in the soil and it gets completely covered in dirty, sticky mud!
According to Gartner, there will be nearly 21 billion devices connected to the Internet by the year 2020. That’s a lot of devices that need to be connected in useful ways. This article shows you the steps to make a Raspberry Pi speak from anywhere in the world using Node.js and PubNub.
This is the continued instruction of "How to Hack RC Car Transmitter via 2.4 GHz nRF24L01 Arduino part1 Tx"The prerequisite instruction have introduced how to hack RC car Transmitter by using nRF24L01 module for Arduino Nano.In this session we will build 2.4 GHz. receiver installed on a RC prototype car that has a Steering servo and Electronic speed control(ESC).Thank to arduino-info.wikispaces.com , github.com/maniacbug/RF24 for RF24 library and other nRF24L01 module information.
This Instructable is designed for educators and tinkerers and details how to create a prototyping base, which contains both an Arduino Uno and a breadboard. You can use this for yourself or make a set for a classroom environment.I use these for the curriculum at the Pier 9 Creative Workshops to teach Arduino fundamentals. With a portable Arudino and breadboard as a single unit, you can reduce the mess of wires everywhere and prevent accidental disconnections from the breadboardI've seen many flavors of acrylic Arduino stands, such as this one (Instructables) and this one (Adafruit). So I certainly didn't come up with this idea, but this version is a clean and elegant implementation.Mine has no nuts-and-bolts and a minimum of parts. The Arduino and breadboard spacing is just the right distance for clean-looking jumper wires. There is plenty of room on the lip of the base for your hands o
The Banana Pi is a small, low power computer board much like the Raspberry Pi. A few details separate the Banana Pi though and make it a better option to be used as a small, nearly silent, headless (no monitor needed) Network Attached Storage device.These are:Gigabit Network interface (10x faster than the Raspberry Pi)Sata port and Sata power for hard drive (Raspberry Pi has only USB ports on a bus shared with the onboard NIC)There are also readily available images for turnkey use of the Banana Pi as a NAS using the excellent Open Media Vault software that is based on the Debian Linux Distro.
Every spring my wife gets really ambitious and plants a big vegetable garden. As the summer drags on, ambition turns to laziness and unfortunately many of the plants die a slow, withering death from neglect due to lack of weeding and watering (except for the tomato plants, which grow like mutants in our climate even if you neglect them...so every August we wind up with 10,000 tomatoes and no other vegetables). While I can't automate some maintenance tasks like weeding*, I can certainly automate the watering and I figure that will give our poor plants a better chance at survival. You can buy all sorts of fancy programmable hose, irrigation, and water timers (not sure about the difference between those three terms, but that's how Lowe's has them listed) if you want to automatically water your garden. But, in the true spirit of Instructables...where's the fun in buying one whe
I apologize if you find spelling errors or nonsensical text, my language is Spanish and has not been easy to translate, I will improve my English to continue composing instructables.In today's technology, especially electronics have come a long way, to the point that today can make projects a few years ago were very complicated to implement, thanks to these technological advances are now able to design and implement our houses projects.and through this article I come to show you my new project, which consists of a wristwatch, so I called Arduino Watch Sport.

UPDATE: Check out step 8 for the latest version of my scanner and a download link for the python scripts.Hi, I am a big Arduino and Raspberry PI fan and also love 3D printing. I wanted to be able to make a 3d model of my kids and started investigating how to build a 3d scanner. I found a lot of solutions out there, but the problem with most of them is that the subject would have to sit still for a while... well I think it would be easier for me to invent a spaceship that can fly to mars then inventing a solution for my 2-year old son to sit still :-( So none of those solutions where going to work. I knew I had to come up with a way to instantly take many images at the same time. So I first started to research what chea
