The microprocessor world seems to be going in ARM direction. And so seems to be microcontrollers. Cheap ARM based 32-bit micro-controllers are taking their place and trying to replace less powerful 8- and 16-bit micro-controllers. I wrote earlier that Arduino Goes ARM. It took quite bit of time for Arduino to take that step and →
PCBs without any substrate article tells that Kimio Kosaka is taking the concept of free-formed circuits to the next level with O’Baka Project No.7. Arduino Skeleton “0′baka Project” means a stupid project. This project is to make things which is not art and which is not usable. It’s a fully functioning Arduino board, without the →
Raspberry Pi and Arduino seems to be the most interesting small single board platforms at the moment for the hobbyists. It is a bit sad to see some people who are very passionate about the Arduino community coming down quite hard on the Raspberry Pi project as the Big Bad, suggesting that we’re trying to →
The Arduino Ethernet Shield connects your Arduino to the internet. Just plug Arduino Ethernet Shield module onto your Arduino board, connect it to your network with an RJ45 cable and follow a few simple instructions to start controlling your world through the internet. The original Arduino Ethernet Shield is based on the Wiznet W5100 ethernet →
Surprisingly Simple Arduino Motion-Sensing Project Makes For Some Weekend Fun article tells that Matt Williamson built a tiny, Arduino-based motion sensor that will SMS you when something moves by your desk or into a room. It’s completely open source and the notifications system runs on your PC thanks to a simple Python script. Why is →
If you have a simple Arduino project that uses only a few pins, you might be able to shrink it down to a single 8-pin ATtiny chip. How-To: Shrinkify Your Arduino Projects video and How-To: Shrinkify Your Arduino Projects article shows you how. The best part is you can use the same Arduino code and →
Fritzing is an interesting open-source initiative to support designers, artists, researchers and hobbyists to work creatively with interactive electronics. We are creating a software and website in the spirit of Processing and Arduino, developing a tool that allows users to document their prototypes, share them with others, teach electronics in a classroom, and to create →
Carnegie Mellon HCI students bring your favorite action hero sound effects to life. Arduino-powered glove brings real sound effects to your make believe gun show article tells that a team from Carnegie Mellon’s Human-Computer Interaction course have built a glove that does some interesting tricks. AHRG: Augmented Hyper-Reality Glove video gives you the idea how →
I just saw Slashdot posting mentioning Open Hardware Journal. Open Hardware Journal is a new open technical journal on designs for physical or electronic objects that are shared as if they were Open Source software. It’s an open journal under a Creative Commons license. You can download the magazine in pdf file format and redistribute →
Implementation UDP into microcontroller Igor Atmel-UDP device: UDP/IP infrared remote control web page shows implementation UDP/IP on firmware level (similar as emulation of RS232 interface or USB interface). What makes it really cool is that the ethernet is bitbanged using nothing but the bare pins of an ATMEGA168. The downside is that this Ethernet implementation →
