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 [...]

The PiServer for the Raspberry Pi

If you were running an institution teaching computer programming to kids using Raspberry Pis (RBPis), then you would normally spend some time updating numerous RBPis with the latest Raspbian and copying over several files for the class. You can save a lot of time using the PiServer, and do away with the SD cards at the same time. The PiServer is a new piece of software tool that can easily set up a network of client RBPis connected to a single x86-based computer acting as the server. The various Read more [...]

Blinkt! is Compatible with the Raspberry Pi

If you are interested in 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 Read more [...]

Raspberry Pi Helps a Hexapod Robot Walk

Roland Pelayo has used the single board computer, the famous Raspberry Pi or RBPi to help a hexapod robot learn to walk. The RBPi allows the robot to run in an autonomous mode, so it walks without assistance, avoiding obstacles. Alternately, it can also operate in a manual mode, whereby a user with a smartphone can control the robot. Most interestingly, the hexapod walker follows the tripod gait, just as most six-legged insects do. Roland prefers to use servomotors to control the gait of the hexapod Read more [...]

Storm Glass Lamp: Raspberry Pi Simulates a Storm

Several people have used the versatile single board computer, the Raspberry Pi or RBPi, as many types of educational devices. In fact, the original purpose of conceiving the RBPi was to use it as an educational instrument to further computer programming among children in schools. It has been serving this purpose excellently, and has managed to go even farther. For instance, the RBPi inspired someone to make a weather-simulation lamp for recreating the weather at any place in the world. The RBPi Read more [...]

Expanding the GPIO on the Raspberry Pi

Although the single board computer the Raspberry Pi or RBPi has nearly 26 GPIO pins in its earlier models and 40 in its latest, there are times when the project demands more of them. In such cases, a GPIO expander is the only solution, and the MCP23S08, a device that Microchip Technology makes provides an easy way to expand the IO pins of a micro-controller using only a 2-wire serial interface. The MCP23S08 works with the I2C protocol as a slave device, providing 8-bit, general purpose, bi-directional Read more [...]

Talk to your Raspberry Pi

The Raspberry Pi Foundation has tied up with Google for a project called the Artificial Intelligence Yourself or AIY. This is a Hardware on Top or HAT project for the Raspberry Pi 3 (RBPi3) to transform the single board computer into a virtual assistant. This is the first time that Google is offering something exclusively for hobbyists, and the kit comes free with the printed issue 57 of the MagPi—the official magazine of the Raspberry Pi. The kit with the MagPi magazine consists of a Voice Read more [...]
