“I’ve been working on creating a cheap, time-lapse camera that people could use to ‘sense’ the world around them. The cost of such a device would be around $10, when all is said and done, and having multiple of these devices would open up options for public computing that people have not considered – a world where people are willing to deploy “personal, public” electronics throughout their environment with the same ubiquity, recyclability and reusability as paper.”

“The temperature and relative humidity of indoor air is an important parameter that can influence indoor microbial survival, abundance, and community structure. Temperature and relative humidity can also be used to infer other information about indoor environments, such as whether or not it is being heated or cooled.”

“Stubby is an evolving hexapod robot which I am making, with contributions from my 6 year old daughter and a co-worker. I have long wanted to make a walking robot, thanks to shows like Stargate SG-1. While Stubby is not the same, it has been a very entertaining and educational project to work on.”

“Some extra hardware and software changes the Raspberry Pi into a DVB-S digital TV transmitter. The code and diagrams are released under the GPL license. Credits: This project would not have been possible without the pioneering done by Jean-François Fourcadier, F4DAY. I also made use of simplifications made by F4AGC, I simply simplified things some more. “

"As we enter 2014, I thought I would post up a recap of what I’m working on. Primarily I’m developing a wireless method for controlling moving vehicles. In my particular case, this is Garden Scale (G) model train locomotives. However the principles and widgets I’m designing could be used to drive almost anything via real time wireless up to a distance of about 300 ft."

"The project consists of eight modules (creatures) that operate independently, but coordinate their efforts to perform a common task. Each module implements a solar panel to collect the energy needed to operate (feeding) and communicates using radio transmissions. These mechanisms allow the system’s overall behavior to mimic the interactions of prairie dog and mongoose colonies."

"In this post, I’ll show how to construct a robot with .NET Gadgeteer and how to control it using a Bluetooth connection from a PC application based on the 32feet.NET library. Let’s start from .NET Gadgeteer part. The base of our robot is the Rover 5 Tank Chassis, that provides two motors that can be easily controlled by the Motor Driver L298 Module."

"This post will be divided down into two main sections: hardware and software. I will try to explain with detail while keeping it short, and cover some of the key elements and choices involved in making this project."

"The Commodore Wi-Fi Modem is built around two main components: The Arduino-compatible MicroView with built-in OLED screen, and the Roving Networks RN-XV or ‘Wifly’ wireless module. These give you significant flexibility to use it as a straight-forward wireless solution for your Commodore, with optional expandability for standalone use or as a platform for interfacing to the outside world.
