Purism ☛ Flipping the Script: Exploring New Paradigms in Secure Mobile Computing
In many countries, PTTs have evolved over time, with some privatizing or merging with other companies. For instance, I spent a seminal part of my earlier career in telecom working for MCI which was the prime mover in breaking up AT&T in 1984 (with the modified final judgment coming in 1986). The acronym PTT is often still used in many contexts to refer to these historical, government run and operated organizations. Their cousins or the new iteration of these companies are often referred to as facilities-based network operators, mobile operators, or just plain cellular carriers.

Arduino ☛ This beautiful table creates art in the sand
Those are both stepper motors and an Arduino UNO Rev3 board controls them through a stepper shield. The Arduino also controls the LED accent lighting, with potentiometer knobs to adjust brightness and the speed of animated transitions.

Tom's Hardware ☛ This Raspberry Pi matrix display tracks flights in real time
We've seen all sorts of cool Raspberry Pi projects through the years that use matrix panels — from simple ideas like this snazzy Pi-powered matrix dashboard to more interactive things like this retro gaming matrix setup. Today, however, we've got something entirely new to share that really shakes up what we've come to expect from these sorts of builds. Maker and developer Wesley G Mitchell has put together a Raspberry Pi-powered flight tracker that outputs to a custom matrix display.
