Daisho open source multitool for phy layer monitoring
At the recently concluded TROOPERS13 conference in Heidelberg, Germany, presenters Michael Ossmann and Dominic Spill revealed the details on their Project Daisho, an open source hardware and software project to build a device that can monitor high speed communication links and pass all of the data back to a host system for analysis. They describe, […]
Arduino Pong game
Pong is the classic video game, essentially the “Hello world” of gaming development. James Bruce, working at the parhaat uudet nettikasinot company, has developed a simple implementation of Pong for the Arduino which requires the addition of only an RCA jack, two 10K potentiometers, a pushbutton and a handful of resistors. The video output is […]

Open SmartWatch Project: Arduino tool chain (alpha)
We recently posted about the Sony Open SmartWatch project. Since then, Arduino enthusiasts and Sony have been working on a proof of concept for how SmartWatch could be setup to work in an Arduino environment. As a result of these efforts, the Arduino crew have published a GitHub project that includes an alpha version of […]
OpenSprinkler, an open-source internet-based sprinkler / irrigation timer
Ray has written a detailed article about his OpenSprinkler 2.0 Arduino-based irrigation controller: OpenSprinkler is an open-source Internet / Ethernet sprinkler timer / controller based on the Arduino platform. It works with standard 24VAC sprinkler valves commonly found in household watering and irrigation systems. You may be planning to buy or have already purchased a commercial […]
BotQueue open source 3d printer over web control software
Developer Zach Hoeken and his friends at BotQueue have released the code for their software which allows 3D printer conrol over the internet. They call it BotQueue. BotQueue lets you control multiple 3D printers through the Internet and turn them into your own manufacturing center. Think cloud-based computing, but for making things in the real […]
Open electroencephalography
Michael Paul Coder obtained his first printed circuit board from Olimex and started with the OpenEEG project years ago, but only recently started dabbling in the measurement of brain waves while dreaming. He’s managed to build a device which can comfortably record brainwaves during sleep. He’s taken that a step further and established the Lucid […]
Sony Open SmartWatch project
Sony’s SmartWatch is an Android compatible watch based on an ARM Cortex-M3 CPU, STM32F205RGY6, from STMicroelectronics and includes Bluetooth capability and a touchscreen. It retails for around $100. Previously, developers could create apps for SmartWatch with the Sony Add-on SDK, but Sony is now opening up the project to allow hackers to create and flash […]
