Mario Böhmer has informed us of his latest project, an Android/Arduino controlled wall socket. Mario writes: To show the basic principal I used a remote wall socket which normally is switched with a remote via a radio frequency of 433 MHz.
What I wanted was to have an Arduino controlling the remote switch to turn on/off the wall socket. Mario started with a commercial remote wall socket normally operated by RF, and hacked it by replacing the RF controller with a 4N35 optocoupler to open and close the switch. All that was left to do was to write an Arduino sketch that listens to the Serial port for incoming data to switch the circuit, a small desktop program which transmits the control data, and as a bonus a small Android app which sends the switching state to the desktop program. Mario’s code is available on github. Thanks Mario! Online : Power over ethernet? There's a shield for that. Online : Easy multithreading on Arduino with Concurrency.

A month or so ago at the dump, I helped Michael harvest the optical sensor out of a skiing machine just as closing time descended upon us. As we got hustled away from the picking pile, he mentioned that he needed it to make a speed governor for a wood cutting and splitting machine. A few days later, Michael turned up at school to show me the breadboarded version of the circuit. He had all the basics in place, the code and mechanisms were working properly and predictably. Next step was to formalize the design and install it on the automatic log splitter. Initially throttle position was held constant by holding the throttle body against a hard stop.

EmailShare 39EmailShare With the recent release of the Arduino MEGA, I’ve been getting quite a few questions about the differences between the various boards. The differences are actually pretty simple, so I figured I’d write a post about it to make it clear.
Basically, from a purely capabilities standpoint, its like this: Arduino < Sanguino < Arduino MEGA If you’re going from a price perspective, its more like this: Sanguino w/o USB to TTL cable < Arduino < Sanguino w/ USB to TTL cable < Arduino MEGA If you’d prefer to get into the nitty gritty, here’s a table with the various functionalities of the boards broken out: Of course, each board serves its own particular niche: If you need a simple, easy, small board for a basic project, the standard Arduino is usually more than enough. Have you made your decision? Long live open source hardware! Finally, there’s probably something I left out or got wrong, so please feel free to correct me if I messed up. Liquidware : Home.

CDM regular Kyle McDonald keeps cranking out wonderful projects. Following up on a tangible music sequencer powered by Skittles (taste the rainbow of fruity beats), and last week’s cheap-but-effective DIY 3D interface, he’s now put the popular DIY electronics platform Arduino to work as a lo-fi effect. He writes: There have been a bunch of projects bent on getting audio out of the Arduino, using them as synths — even Lady Ada’s more recent Wave Shield ( Kyle’s site, complete with lots of other projects Great stuff! GamePack. Were you ever the kind of person to hack up your own Playstation controllers and hook it up to something else? Well, those shards of plastic can be mighty dangerous, so I’ve done it for you. And hey, with the GamePack you’ll even have something you can hook it up to.
The GamePack comes with an Arduino, MeCap Backpack, TouchShield Stealth or Slide, ExtenderShield and an InputShield- everything you need to create your own open source, portable gaming device. Want to create a whole new gaming platform? Why not? I’ve just added a new option for wide screen that includes the new TouchShield Slide. Components Specifications TouchShield Slide: 320×240 LCD Screen Resistive Touch Screen Holds 60 128×128 bitmap images Compatible with Arduino Environment Only Uses Arduino Pins: 3 and 4 Graphics Library Ready to Go Draw Shapes, Pixels, Colors, Graphs, Buttons 2.83 inch diagonal Tutorials/Blogs Reference and Firmware Media Another shot of the Open Source Gameboy Project.
