What We All Want - Purism
What we don’t want is equally simple: We don’t want to be spied on, controlled, oppressed, forced nor exploited.

Multi-function device displays PC data and news | Arduino Blog
While the typical computer user doesn’t need to worry about it, those of us who overclock our computers or run them hard like to know how they’re performing. If, for example, you overclock your CPU, then you probably want to keep an eye on its temperature to ensure that it doesn’t exceed a safe level. This multi-function device, designed by Mirko Pavleski, displays all kinds of PC data and even current news.
This Arduino LCD Info Panel works with open source software (LCD Smartie) running on a Windows PC. That software monitors many data points, including CPU load, free disk space, memory usage, and much more. It can also download RSS news feeds and sync with other software, like Winamp. The software then sends the relevant data to the Arduino LCD Info Panel device via a USB connection. The unit displays the data on a 16×2 character backlit LCD screen and a pair of potentiometer knobs let the user flip through the data.

The Arduino Launch Control System is a model rocket enthusiast’s dream | Arduino Blog
Conventional hobby model rockets get their thrust from disposable motors containing an explosive propellant, like black powder. But unlike the gun powder in a firearm’s cartridge that uses a concussion-activated primer to ignite, model rocket enthusiasts ignite their motors using an electric arc. Simple launch controllers consist of little more than a battery, boost converter, and cables. But if you want something fancy, you should check out the Arduino Launch Control System.
This robust launch controller provides environmental data and a great deal of safety. Its built-in sensors provides three key data points: temperature, humidity, and barometric pressure. That information can convey valuable insight when evaluating the performance of a rocket. On the safety side, this launch controller forces several layers of redundancy and checks. To launch a rocket, the user must connect two power supplies, insert and turn a key, push the safety and fire buttons at the same time, and hold those buttons for the entire countdown. That focus on safety makes this launch controller perfect for younger hobbyists.
