Networking 400 Balloons with XBees
Updated: 2012-08-31 21:30:57
Rob Faludi, author of Building Wireless Sensor Networks, is helping to light up the sky with XBees: This week I’m heading to Newcastle upon Tyne in the U.K. for Connecting Light, 400 giant illuminated balloons that will cross England coast to coast along Hadrian’s Wall, a 2000-year-old Roman barrier. This [...]
We thought that connecting an Arduino to a Raspberry Pi was overkill, but one thing caught our attention. [Jan Stevens] mentions that the RPi is less expensive than the Ethernet Shield. Interesting. As we looked into his writeup a bit more we began to think he’s onto something. [Jan] uses the PHP serial class to [...]
Ecco il primo di una serie di workshop che Officine Arduino organizzerà in Italia. Quale luogo migliore da cui iniziare se non la capitale? Abbiamo parlato / immaginato / organizzato con molte persone in questi mesi – da Trieste in giù – ed il buon Alex Giordano lo ha già ribattezzato come il “Tour di [...]
This tutorial will guide you through the process of building a tachometer around an Arduino. Tachometers are used to measure rotation rate in Revolutions Per Minute (RPM). You don’t need much in the way of hardware, this version uses an Infrared beam to measure fan speed. As with last year’s PIC-based tutorial, [Chris] is using [...]
If you want to learn about microcontrollers in a classroom setting but don’t have the time (or money) to attend university lectures you are in luck. Bruce Land who teaches the popular ECE4760 Microcontrolle course has just posted the lecture videos online. This means you can get the benefit of this great Cornell course [...]
Discerning shapes and recognizing objects takes humans several years to learn and it is an essential skill to survive and interact with the world around us. Machines also need to learn this important skill and although some researchers have made progress in recognizing objects, shapes and faces, vision processing is still very complex and there is much more work to [...]
Jon Bennett from JBProjects.net has just completed his latest creation. He purchased a cheap $9 remote control car, added a bit of electronics and now has a car that allows complete control using an Arduino. He has PWM control over the motors to give the car some refined control. All of the code has [...]
Who said you need to upgrade your motherboard to get USB? Just buy this $100 adapter and magically upgrade your parallel port to USB. I wonder if it has drivers for the Windows 95 you have on the computer though. I guess another option would be to just purchase a used computer that has [...]
I enjoy fishing and try to get out at least 2 or 3 times a year. Sometimes the fish are biting like crazy but other times they are just not very active. I think with a Underwater Exploration Vehicle like the Nøkken 3 ROV the fishing experience would be totally changed. I can imagine [...]
IronJungle was inspired by my Multimeter Clock when he built his Voltmeter Clock that also displays Temperature. He used a PicAxe as the microcontroller and has interfaced to a DS1307 Real Time Clock and a DS18B20 Temperature Sensor. Three trim pots were used to adjust the meters to full scale in setup mode. [...]
[Andy] has been hard at work reverse-engineering the Nokia N82 2.4 inch cell phone display for use with an Arduino. As pointed out in the article, this same 2.4 inch display can be found in at least seven other Nokia products, so they are readily available. The panels can be found for as low as [...]
If you have a spare SCARA Arm kicking around and need a new project this 3D Printer built using a SCARA Arm might spark some inspiration. Via: Make “This project documents the re-purposing of a ‘rescued’ 1980′s IBM 7575 SCARA Robot Arm, into a functional 3D ABS printer. The project features some motor upgrades, [...]
The Arduino Wifi Shield is finally here! We’ve been working for a while on this new wifi shield for Arduino that is quite different from what you can find already on the market. Instead of just getting the usual pre-made module we decided to build a product that would encourage hacking and modifications so we [...]
We think it’s a great learning experience to tear back the veil of abstraction and learn a bit more about the hardware found on an Arduino board. This project is a great example. [Scott Daniels] takes a look at the other voltage measurement options available to AVR chips used by Arduino. If you’ve used the [...]
Hey look, an Arduino without its clothes on. This one’s just started its journey to becoming the ubiquitous prototyping tool. The image is from [Bunnie's] recent tour of the fab house where Arduino boards are made. As it says on every true Arduino board, they’re made in Italy. [Bunnie's] trip to the factory happened in Scarmagno, [...]
Open Electronics‘ staff were looking for a common and standard hardware platform usable on different robots they were working on. Their goal was to find a single platform that had to provide power supply to the microcontroller, it had to provide stabilized voltage for the servos, and, finally, it had to be equipped with an [...]
