A quiet revolution is taking place in electronics hardware design and, as silicon integration has continued, engineers are gradually moving from developing mostly at the component and circuit level to working more with board, modules and subsystems.

There are many advantages that lie in a shift to modular design. One is greater ability to share in the economies of scale that come from the use of platforms that attract many customers. Industrial users have a long experience with modular hardware. The Versa Module Eurocard (VME) and CompactPCI standards provided integrators and Original Equipment Manufacturers (OEMs) working in low-volume markets with the ability to use high-performance computing. They could perform more extensive customisation of a computer’s capabilities without having to invest time and effort in high-end printed circuit board (PCB) design. Since those days, Moore’s Law has delivered incredible gains in functionality while also reducing the cost of individual parts. The Raspberry Pi single board computer is a key example.

Null Byte explains how to Use Android & Raspberry Pi for Local Voice communications.

It can be difficult to communicate off the grid when there’s no infrastructure. That’s also true when you’re in situations where there is no cellular service or reliable Wi-Fi hotspots, such as a convoy of vehicles that want to talk to talk to each other, or protestors around the world where law enforcement cut out the cell signals.

On this episode of Cyber Weapons Lab, we’ll show how you can use a cheap $35 Raspberry Pi with PirateBox to enable Android phones to talk to each other without using any cell towers.

Who doesn’t appreciate good BBQ?

Well, maybe some people don’t but I certainly do and that means more for me. Winking smile

In this video, Cam Soper comes on to show us another one of this home projects.

Cam tells us the story of how a Raspberry PI, a chat bot, and a little .NET Core allows him to control his smoker and make great BBQ!
