Because we can!
Sometimes, when I show my projects, I am asked… why did you build it? At last, I found a good answer in the tv show The Big Bang Theory 😉

The Massachusetts Institute of Technology (MIT) and Harvard University announced today a joint partnership to offer a new e-learning platform, called edX. Goal of the project is to offer online courses on different subjects (mainly related to information technology) for free. The project will develop a new e-learning platform that will be released with an opensource license. It will be certainly a…
In a previous post I reviewed the Bluegiga WT11 Bluetooth module, now I’m going to show how to create a serial link.
Tom, from Milwaukee Hacker Space, tested a very fast way to etch your circuit boards: he uses a mix of muriatic acid and high-concentrated (30%) hydrogen peroxide and wipes the copper away with a sponge. Here’s a video showing the board completely cleaned in few seconds: Please be careful with the acid and work in a…
In this blog post, I’m going to show you how to write a sketch to update a DNS record hosted by one of the most famous Dynamic DNS service providers, no-ip.
Thanks to Farnell, I was able to test the Bluegiga WT11 bluetooth module. The module, which is Bluetooth 2.1 compliant, contains three main elements: [checklist] the tranceiver the chip antenna a complete Bluetooth stack (named iWrap) [/checklist] The power transmission – it’s a class 1 device – is 17dBm that corresponds to a range, in open air, of about 200m. Layout Module’s dimensions –…
A useful feature added in Windows 7 is the jump list you can get with a right click on Windows Explorer icon located in the taskbar. You can also “pin” some resources in the top pinned list: Because of a bug, if you previously added to pinned list a resource (for example a network share) not available anymore, you can’t remove that resource.…
Working with a Windows cluster, I needed a way to run scheduled tasks only on the cluster node that is owner of a given cluster group. In Windows 2003 it was possible to configure Task Scheduler as a cluster resource; I wasn’t able to find a way to do the same in Windows 2008. I created a simple PowerShell script that checks…
In this third blog post, I’m going to show you the logical view of my Nixie clock and two of its main elements: the real time clock, to keep track of the current time, and the expander, to add more I/O lines.
Dave devloped a very interesting tool for Arduino IDE, called Upload-And-Retrieve-Source. With that tool, you can use Github as a repository for your sketches: you can upload and retrieve them using friendly menu items: Github also features version tracking: Via: Hack a Day
