Keeping Your Raspberry Pi Cool

Any PC motherboard is practically useless until you add some cooling and other accessories. This is because modern processors require cooling as they generate heat when operating. This is regardless of whether the processor is an x86, x64, an ARM based system such as the Raspberry Pi (RBPi), any other Linux or Android chipset, MIPs, or belonging to any other design. The general explanation is the internal circuitry within the processor is microscopic and does not have the adequate surface area to Read more [...]

Blinkt! is Compatible with the Raspberry Pi

If you are keen on learning how to control RGB LEDs with the Raspberry Pi (RBPi) single board computer, Blinkt! provides a simple way to interface. Blinkt! is a strip of eight superbright RGB LED lights that you can connect to the RBPi without wires, so it is an easy way to start. Blinkt! Has a female connector that matches the male GPIO connector on the RBPi, and that allows the tiny LED board to sit atop the RBPi. The RBPi can individually control each of the eight APA102 RGB LEDs on the Blinkt! Read more [...]

Your Own Home Assistant with the Raspberry Pi

In the past one year, several off-the-shelf home assistants have made their way to the market. Some of the most famous of them are Siri, Google Home, and Amazon Alexa. For people too lazy to move, it is a pleasure to simply announce, “…, resume my audiobook“ or, “…, turn off the bathroom light,” and let the assistant do their bidding. In this melee of big names, there are several home-brew variants as well, some of them built on to single board computers such as the Raspberry Pi (RBPi). Read more [...]

Raspberry Pi Drives the Oton Glass

Imagine standing in front of several road signs but unable to locate the one you want, because they are all written in a foreign language. This is the job for the OTON GLASS, a device to capture the image, translate it to a language of your choice, and read it to you in your ear. Not only will this help travelers abroad, but also help people with poor vision and those suffering from dyslexia. Oton Glass is the effort of Keisuke Shimakage, who says he was inspired to develop the device by his father’s Read more [...]

ASUS Tinker Board Competes with the Raspberry Pi

With the advent of the Raspberry Pi (RBPi), the popularity of single board computers (SBCs) has risen rapidly over the last five years. The RBPi has easy software and a low price that has won it a vibrant community consisting of not only coding hobbyists, but also teachers and children, whose minds and hearts it has captured. This success of the RBPi has led to scores of other vendors pitching in with their SBCs. Among them, ASUS is the latest with its Tinker Board SBC, challenging the RBPi. The Read more [...]

Using Raspberry Pi to Monitor the Environment

Many cities in the world are plagued with poor quality of air caused mostly by pollution form old diesel cars. This is true of Peru also, and James Puderer is using Raspberry Pis (RBPis) fitted in several taxis to monitor the air quality. James fitted the RBPis in the hollow vinyl roof sign almost all taxicabs use in Peru. James uses the RBPi along with various Adafruit technologies, such as the BME280 sensor for temperature, humidity, and pressure. He has created a retrofit setup powered by a battery Read more [...]

Beemo Works With Raspberry Pi

Even adults watching Adventure Time wish to own a personal BMO, the quirky living game system from the Be More episode of the show. Although based on the GameBoy, BMO is a digital friend calling out through the nostalgia lens of our childhood times. Now Bob Herzberg has created Beemo, a BMO for his daughter and her friends. In building the living little boy, Beemo, Herzberg used the popular single board computer Raspberry Pi (RBPi), which be runs on battery power, a USB battery pack. Although his Read more [...]

GrovePi Kits for the Raspberry Pi

If you are looking to interface sensors to the Raspberry Pi (RBPi), the popular single board computer, GrovePi+ from Dexter Industries (SEED Studios) makes it very easy with their starter kit. The kit carries a GrovePi+ board, including more than 10 carefully selected sensors along with the necessary interfacing cables. The kit is very easy to use, as the user only has to plug the GrovePi+ board over your RBPi, and connect the necessary sensor to the board. GrovePi provides a powerful platform for Read more [...]

Industrializing your Raspberry Pi

You can turn your Raspberry Pi (RBPi) into a completed computer system with the minimal effort. Using a pre-assembled, cost-effective kit will not only save you a lot of time, but also speed up the installation and slash development time as well, allowing you to realize the full potential of your single board computer. This industrialization of your SBC brings huge commercial potential and encompasses a wide range of applications, including using the system for payment terminals, communication systems, Read more [...]

Interfacing XBee Modules with the Raspberry Pi

You can use two XBee modules to exchange data between them, as they are modular, self-contained, and low-cost components using radio frequency to communicate. Most XBee modules transmit on the ling-range 900 MHz or on 2.4 GHz using their own network protocol. The primary advantage of using XBee modules is their size—nearly as large as a postage stamp. Therefore, it becomes easy to use them as sensor nodes in small projects. They consume very low power, and incorporate a special sleep mode that Read more [...]
