Boris Landoni writes about an open source sprinkler system powered by Yún:

A control unit for the garden sprinkler that can be controlled via web and smartphone thanks to Arduino Yún.
With summer approaching, our plants and our gardens need some regular watering in order to stay lush and green as we like them. It’s not easy to always remember to water plants and gardens and try to always be at home at the same time every day, so we asked ourselves, instead of taking some time every day to water plants and flowers, wouldn’t it be better to take advantage of our passion for electronics and realize an automatic system to do this for us? This is the idea at the base of the project we are going to show you in this article, which consists of a control unit for a garden sprinkler based on Arduino Yùn and a relay board that can interconnect with it. Control unit can manage a configurable number of outputs, a rain sensor and it can be programmed through a web interface reachable from any PC or smartphone connected to your home network. By adequately configuring the router where the sprinkler will be installed, you will even be able to control the system from the Internet.

Boris Landoni from Open Electronics writes about a new open source Demoboard MP3 audio player DFR0299:

Let’s test out the capabilities of the DFR0299 audio player module, an ideal choice for Arduino but also for many stand-alone applications.

In this article, we decided to design and propose a demoboard for the DFR0299 module we already used in the ‘Presepino’ project; this module will function as a development platform for various application or just to program multiple circuits in the event of small productions.

MeArm Pi – Build your own Raspberry Pi powered robot arm!

via Dangerous Prototypes

mearm

Here’s an interesting open source project on Kickstarter the world’s first robot arm kit for the Raspberry Pi, the MeArm Pi:

We believe in helping people understand how the world works. With so much development going on in robotics at the moment, now is the perfect time to get to know what it takes to build your own robot. The MeArm Pi is an award winning robotic arm kit that’s simple enough for a child to assemble. It integrates directly with the Raspberry Pi you know and love and you can either control it directly using the on-board joysticks or by programming it from the Pi in your favourite programming language.

Take control of the world around you.

You can visit the project’s Kickstart page and their website Mime Industries for more info.

A FPGA controlled RGB LED MATRIX for Incredible Effects – the Hardware

Boris Landoni from Open Electronics writes:

In this post you will find  the description of a graphic display that uses a modular solution based on dot matrix blocks (in which each dot is a RGB LED), that are driven – via a specific bus – by a very powerful control board, that is entirely programmable and capable of managing even very fast animations, thanks to the FPGA it is supplied with. Yes, the key factor is the Spartan-6 Field Programmable Gate Array by Xilinx, that is able to execute programs at very high speed, thanks to its parallel processing capability (multi-thread); the model that has been used in the project was chosen because it represents the most performing FPGA available on the market as a TQFP package, therefore it may still be soldered by means of the traditional tools.
