Suppose you want to create an electronic circuit and a corresponding printed-circuit board for it. What software will you use? Unless you already have a favorite, it might be hard to decide: There’s a dizzying array of options, ranging from free software typically targeted at students and hobbyists to multithousand-dollar packages used by professionals. The […]

I2C is a multi-device bus used to connect low-speed peripherals to computers and embedded systems. The Raspberry Pi supports this interface on its GPIO header and it is a great way to connect sensors and devices. Once configured you can connect more than one device without using up additional pins on the header. Before using I2C

This is a basic prototyping kit for the Raspberry Pi. It will allow you to quickly and easily prototype your hardware ideas without the needing to buy new kit each time. It is also compact, portable, and a lot more durable than most prototyping kits. You can either build simple circuits on the top of

I have a small application continuously running on Raspberry Pi board. Sometimes, in my country, we have (short time) mains power failures. In such situation, my Raspberry board, powered by the wall adapter, turns off immediatly, without any attention for open files, transmissions in act, etcetera. This is really a problem. I decided to use

Geiger counters are basically just devices which enable us to measure ionizing radiation. In the context of human activity we have to deal with natural radiation sources and artificial ones. Some of the materials emitting ionizing radiation are used to create electricity, others were used to stockpile thermonuclear bombs, so many could get scared and

The Raspberry Pi was originally designed to be a tool for hands-on learning about how computers work. It is also a tool that can be used to make all sorts of creative programming projects. The point of the Pi is to be accessible, and I have made this short illustrated introduction for people who are

The Raspberry Pi is a remarkable machine. Lightweight, powerful, and until now it was completely tethered to a wall socket. The LapPi is built to free the Pi! It’s made from a mixture of spare parts, unallocated electronics, and scrapped components & cables I have built it in response to the Raspberry Pi Challenge. The

Replacing a simple and inexpensive remote cable release for your camera with Raspberry Pi may seem like a classic case of over-engineering, but using the tiny machine to control the camera opens up a whole new world of photographic opportunities. Using a simple Python script, you can turn Raspberry Pi into a powerful and flexible intervalometer or trigger
