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 [...]

Let Raspberry Pi Automate those Snake Eyes

If you are looking for something to bring your cosplay masks, props, or other spooky sculptures to life for your robots, animatronics, or Halloween parties, you can use the snake eyes cowl as a pair of animated eyes. This is an accessory for operating two 128x128 pixel TFT LCD or OLED displays through a single board computer such as the Raspberry Pi (RBPi). It also has four analog sensor inputs. The project started life as a project named Electronic Animated Eyes using the microcontroller Teensy 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 [...]

Facial and Object Recognition with A Raspberry Pi

f you are using the single board computer Raspberry Pi (RBPi) for vision-related tasks such as facial and object recognition, the NCS or Movidius Neural Compute Stick from Intel could help to boost the rate at which the RBPi carries out its tasks—you actually do not need to employ a server farm for the job. The RBPi is fully capable of running software for facial image recognition, and hobbyists have long being using the SBC for recognizing faces in videos to identifying obstacles in the path Read more [...]

Raspberry Pi Control for Pool Temperature and Motor

Owners of swimming pools often have no idea of the temperature of the water in the pool relative to the surrounding air. They also are unable to control the pump schedules unless they put up a mains timer. However, using a single board computer such as the Raspberry Pi (RBPi) makes it easy to display the temperature on a webpage, while it switches the pump automatically on or off based on a preset schedule. The pool monitoring system does not need a full version of the RBPi, as the RBPiZW, the Zero Read more [...]

Interfacing the Tilt Hydrometer and Thermometer to the Raspberry Pi

Tilt is a wireless hydrometer and thermometer combination suitable for home brewers that allow instant readout of the specific gravity of your brew. You can see the specific gravity readings on your Apple iPhone, iPad, or Android smartphone. Furthermore, Tilt can talk to your single board computer, the Raspberry Pi (RBPi). Tilt will talk to most devices sporting the Bluetooth 4.0+ interface. Once you have the data in your device, you can optionally save the data automatically into a cloud using Read more [...]

Using the Raspberry Pi to Secure IoT

The popular single board computer, the Raspberry Pi (RBPi), can effectively secure systems that traditional protection mechanisms often cannot. Industrial control system networks and Internet of Things fall under this category. You can use the RBPi2B and later models as an adequate medium for running the various security tools. For this project, you need a Micro SD card of at least 8 GB size, and the bigger it is the better, as you can use the extra space to store a longer log data history, for Read more [...]
