New Arduinos – Pro & Pro Mini

Posted by & filed under Arduino, Electronics, Open-source.

Sparkfun & Arduino announced today the new Arduino Pro ($20) and Arduino Pro Mini ($19), two 3.3V “low-cost, low-profile boards intended for advanced users and for convenient embedding in long-term projects”. The Arduino Pro is shield compatible (but 3.3v, beware) and includes a connector for lithium ion batteries. The Arduino Pro Mini is well….mini at… Read more »

The Arduino Family – Arduino Diecimilla (continued)

Posted by & filed under Arduino, Electronics, Open-source.

In a previous post I reviewed the Arduino Diecimilla and some of its shields. The Diecimilla and its proto-shield provide us with a great sandbox for experimenting with basic circuits on a mini-breadboard. If you can leverage some of its shields to provide additional functionality you don’t want to have to implement yourself (GPS, SD… Read more »

USB/LCD Part 1 (SerLCD on FT232L)

Posted by & filed under Arduino, Electronics, Open-source, Personal.

As I read blogs and articles about DIY electronics projects, I learn about gizmos that I want to gain first hand knowledge on. One such are small LCD screens (not monitors !) which are available from many vendors. Following the Arduino tutorial, I discovered that many require up to 11 pins on the Arduino. Sparkfun… Read more »

Making things talk

Posted by & filed under Arduino, Electronics, Open-source, Personal.

The Arduino Starter Pack from Adafruit is really pretty cool. It provides a really nice starting point for open source hardware hacking. In addition to the main Arduino Diecimila board, the starter pack includes a few components to play with (resistors, push buttons, LEDs, …) as well as a protoshield to start prototyping with the… Read more »

Arduino – the beginnings

Posted by & filed under Arduino, Electronics, Mac OS X, Open-source, Personal.

I am not much for DIY, home projects. I am still struggling with putting curtains up in my TV room. However, while casually browsing different sites (including Make) I discovered the Arduino board, an easy to use electronic kit based on a powerful Microcontroller that spawned a family of companion products. This ecosystem makes it… Read more »

Photo Gallery Statistics

Posted by & filed under Open-source, Personal, Photography, Web Site.

At home in Provence for a few days, I decided to code a few things. Here is one, a statistics page for my gallery, powered by ZenPhoto, which shows a few different charts such as this one: I am using the rather new Google Chart API to generate the charts.

Open Source SIP client for Mac OS X (Part 2)

Posted by & filed under Linux, Mac OS X, Open-source.

So one interesting thing to look at with Mint or any other site traffic analytics application is where traffic comes from. A lot of it comes from searches and a popular one here is “Open Source SIP client for Mac OS X”. That’s something I was researching when I was interviewing for a startup a… Read more »
