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 [...]

Pro-HAT & GPIO-Zero for the Raspberry Pi

HATs or Hardware Attached on Top are very popular with the Raspberry Pi (RBPi) community. They plug on to the GPIO pins on the RBPi, providing additional functionality to the single board computer. The Pro-HAT puts the GPIO ports of an RBPi in numerical order, and labels them clearly. The user gets a female socket for each port into which, they can plug their wires or component leads. Pro-HAT is actually a 72-point breadboard with the arranged GPIO ports and includes plenty of power and GND sockets, Read more [...]

A Rain Alert for the Raspberry Pi

This Raspberry Pi (RBPi) rain alert will let you know when it starts to rain, so you can reel in the clothes you had let out to dry after washing. Although the kit uses an RBPi3, any model of the RBPi family can easily handle this project. A later extension can make it send tweets as well, but for now, it simply triggers a buzzer. The primary sensor in this project senses falling raindrops. This raindrop sensor is actually a printed circuit board with two traces running across the entire board in Read more [...]

Working with Gas Sensors and the Raspberry Pi

Many devices predicted by earlier science fiction stories and movies have come true. Among them are gas detectors as envisaged by the TV series Star Trek. If you have a single board computer such as the Raspberry Pi (RBPi), you can use it to detect the type of gas and air quality around you. Of course, you will need to couple the RBPI with a gas sensor, and among the popular gas sensors available are the BME680 from Bosch, and the CCS811 from AMS. Gas sensors are helpful in sniffing out volatile Read more [...]
