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 [...]

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 [...]

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 [...]

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 [...]

Audio HAT for the Raspberry Pi Zero

The Raspberry Pi Zero (RBPiZ) and its successor, the Raspberry Pi Zero Wireless (RBPiZW) are very small single board computers. The Pi Foundation wanted to keep their cost and size to the low side, so they did not include either a 3.5 mm audio jack or any other audio port. Although this may seem like a setback for many users, some of them were went ahead and figured out how to get audio out of the board with a little hacking. Another reason for not including an audio port is the Broadcom chipset Read more [...]

VNC: Controlling a Raspberry Pi from Anywhere

Sometime you wish you could remotely control your Single Board Computer (SBC), the Raspberry Pi (RBPi). This could be because you have set up your RBPi as a home security system with a camera that you want to monitor remotely, or the RBPi is in control of some appliance that you would like to switch on/off from a remote location. Ordinarily, to access an RBPi from outside your home network, you would need to give it an IP address, and set up your home router accordingly. However, there is another Read more [...]

RS485 & Raspberry Pi: Monitoring Power

Commercial data centers, lighting controls, utility rooms for buildings, and others need to keep a tab on their power consumption. The normal way to do this is by using electronic voltage meters and multi-branch current monitoring circuits. Vytas Sinkevicius wants to monitor power consumption using the ubiquitous single board computer, the Raspberry Pi (RBPi) as the main controller and the RS485 interface in a Branch Current Monitor (BCM) system. The heart of the power monitoring system is an Read more [...]

Monitor Appliances with Raspberry Pi

We use many appliances to help us around the house and office. However, most of them are not smart enough to inform us when they have finished the chore allotted to them. That means we have to leave whatever we are doing at intervals to check and monitor the state of the appliances. This reduces our efficiency for doing important work requiring long stretches of concentration. All this can be set right if you have the single board computer, the Raspberry Pi (RBPi) readily available. You can program Read more [...]
