A new opensource robotics project is releasing in France called the Poppy Project.
Poppy is an Open-source humanoid platform based on robust, flexible, easy-to-use hardware and software.
Designed by the Flowers Lab at Inria Bordeaux and Ensta ParisTech (France), its development aims at providing an affordable and hackable humanoid robot for science, education, art and geeks.
Poppy was initially made for our research project about understanding biped locomotion, and full-body physical and social interaction in robots and humans.
Arduino is ready for Maker Faire Bay Area, and you?
A new product – Arduino Robot brings you into the world of robotics. Designed with Complubot, the 4-times world champions in Robocup Junior robotics soccer, the robot allows for endless hours of experimentation and play. It is a self-contained platform allowing you to build interactive machines to explore the world. You can use it as it is, modify its software and even add your own hardware on top of it. You can learn as you go: the Arduino Robot is perfect for the novice but also for those looking for their next challenge.
?As always with Arduino, every element of the platform – hardware, software and documentation – is freely available and open-source. This means you can learn exactly how it’s made and use its design as the starting point for your own robots.
A new software – Arduino has released the new version of the Arduino IDE and the new TFT screen. TCT LCD library relies on the Adafruit GFX and ST7735 libraries. Adafruit was founded in 2005 by MIT engineer Limor ‘Ladyada’, Enterpreneur of the year 2012. The Arduino specific library, named TFT, extends the Adafruit libraries to support more Processing-like methods. You can write text, draw shapes, and show bitmap images on the screen in a way that should be familiar to users of Processing.
Ray Wang wrote this post about voltage conversion from 24VAC to 5VDC.
Voltage conversion from 24VAC to 5VDC is quite useful, because a lot of home automation devices use 24VAC, including sprinkler solenoids, home surveillance systems etc. Having a conversion module makes it easy to use a single power supply, without a separate 5V adapter for your control circuit. There are plenty of resources you can find online about it. But these resources are rather scattered. So in this blog post I summarize and discuss the common choices.

Eric Evenchick at Hackaday.com is developing templates to make firmware development easier for the open source community. It’s definately something worth looking into. You can find the original story at Hackaday here. The project files are on Github here.
Most microcontroller manufacturers give you some kind of free development toolchain or IDE with their silicon products. Often it’s crippled, closed source, and a large download. This is pretty inconvenient when you want to have firmware that’s easy to build and distribute. I’ve found many of these toolchains to be annoying to use, and requiring closed source software to build open source firmware seems less than desirable.
It’s possible to build code for most microcontrollers using command line tools. You’ll need a compiler, the device manufacturer’s libraries and header files, and some method of flashing the device. A lot of these tools are open source, which lets you have an open source toolchain that builds your project.
Setting up these tools can be a bit tricky, so I’m building a set of templates to make it easier. Each template has instructions on setting up the toolchain, a Makefile to build the firmware, and sample code to get up and running quickly. It’s all public domain, so you can use it for whatever you’d like.
Currently there’s support for AVR, MSP430, Stellaris ARM, and STM32L1. More devices are in the works, and suggestions are welcome. Hopefully this helps people get started building firmware that’s easy to build and distribute with projects.
