ATtiny Remote Power Switch for the Raspberry Pi

One of the shortcomings of most highly popular single board computers such as the Raspberry Pi (RBPi) is the lack of an on/off power switch. The board springs to life as soon as you insert the micro USB power cable into its socket. If you simply switch off power or pull out the micro USB cable off the RBPi, you stand the risk of not only losing data but also of corrupting the file system. Therefore, to shutdown the RBPi safely, you need to call a shutdown command, which closes down the file system Read more [...]

ElectroSmash Pedal for the Raspberry Pi

Guitarists favor expensive gear. For instance, they hold online discussions about the best types of wire for guitar pickups. They even go to great lengths while selecting the type of transistors that will give them the best fuzz tone. They hold extensive discussions about the merits of the pentode rectifier over the tetrode type. While the geeks in the electronics world share several common characteristics with the guitar geeks, the ElectroSmash Pedal Pi would interest both. Both teams are already Read more [...]

A Smart Development Board for the Raspberry Pi

The Raspberry Pi or RBPi single board computer when fortified with Cloudio makes a personal IoT computer that users can play with or use for prototyping. Cloudio, the add-on board suitable for the RBPi, offers advanced features such as sensor monitoring and displaying on dashboard, providing custom notifications with image and video, unlimited cloud services, one tap upload for multi-boards, voice assistant capabilities, IFTTT integration, drag and drop programming for Android and iOS, and much more. As Read more [...]

Industrial Controls and the Raspberry Pi

Industries with control equipment prefer to use a standardized system of mounting components such as circuit breakers within equipment racks. The most popular arrangement is the DIN rail and enclosure. The rails are typically made from a cold-rolled carbon steel sheet and zinc-plated or chromated for a bright surface finish. DIN is the acronym for Deutsches Institut fur Normung in Germany, and the rest of the world has adopted their standards as the EN and IEC standards. The famous single board Read more [...]

Raspberry Pi to Linux Desktop

You may have bought a new Single Board Computer (SBC), and by any chance, it is the ubiquitous Raspberry Pi (RBPi). You have probably had scores of projects lined up to try on the new RBPi, and you have enjoyed countless hours of fun and excitement on your SBC. After having exhausted all the listed projects, you are searching for newer projects to try on. Instead of allowing the RBPi to remain idle in a corner, why not turn it into a Linux desktop? At least, until another overwhelming project turns Read more [...]

Let the Raspberry Pi Monitor Energy

If you are looking for monitoring energy remotely, an open source system that uses the ever-popular single board computer, the Raspberry Pi (RBPi) may be suitable. The company, OpenEnergyMonitor, makes the open-source tools for monitoring energy, and at present, they are using the RBPi3. According to their co-founder Glyn Hudson, the aim of OpenEnergyMonitor is to help people understand and relate to how they use energy from their energy systems, and the challenges of sustainable energy. The system Read more [...]

A Soundcard HAT for the Raspberry Pi

If you have been wondering how to use the popular Raspberry Pi (RBPi) single board computer for effects to be used with musical instruments such as the guitar, the Pisound board from Blokas may be the answer. With the Pisound board, any musician can connect any type of audio gear to the RBPi, and bring their project to an entirely new level. Pisound is a soundcard HAT for the RBPi. HAT is an acronym for Hardware Attached on Top of an RBPi. HAT boards have an EEPROM that tells the RBPi the values Read more [...]

How to Simulate the Raspberry Pi?

You may have an urgent project that requires the use of a Raspberry Pi (RBPi), but do not have immediate access to a physical kit or the SBC. However, that should not hamper your progress with the project, as Microsoft is now offering an online RBPi simulator. The online RBPi simulator allows users to write code for controlling emulated hardware. Therefore, for the present, users can interact with a sensor to collect data from it and control an LED. On the simulator, the user has a graphic of an Read more [...]

BrailleBox with the Raspberry Pi

Reading, whether online or from the page of a book is a simple affair for those endowed with the power of sight. However, for those who are sightless, or have lost their eyesight, totally or partially, reading can be cumbersome, if not impossible. The Braille system, by allowing a changeover to the sense of touch, helps sight-impaired people to read. Braille uses a system of raised dots that blind or those with low vision can follow with their fingertips. It is not a separate language, but rather Read more [...]

Sensor Nodes Based on the Raspberry Pi

Building sensor networks is economical if a microcontroller hosts the sensors. However, sometimes the computational power a microcontroller offers is not adequate. For instance, it may be necessary to convert the data to a different format, print a hard copy of the sensor data, or incorporate the data within an application. What you need is a computer that not only has more processing power, but also allows the use of common applications, affords access to peripherals, and permits the use of scripting Read more [...]
