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 [...]

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 [...]

Two Raspberry Pi HAT Controller Modules

Atomo Systems, from Hong Kong, will be producing the Atomo Modular Electronic System for building electronic projects with four parts—Control, IO, Power, and Connector. The system also includes two low-cost HAT modules with onboard ARM MCUs compatible to the Raspberry Pi (RBPi). The combined controller connector board uses a small and inexpensive MCU, similar to what an Arduino Uno uses. However, the ARM MCU is faster, has more IO, and is better compatible with the RBPi. The idea behind building 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 [...]

Raspberry Pi Zero Goes Wireless

The Raspberry Pi product line has added a new member, the Raspberry Pi Zero W (RBPiZW), an updated version of the RBPi Zero, with the added advantages on on-board Wi-Fi and Bluetooth capability. Although the new RBPiZW lacks the Ethernet and full-sized USB-A ports, it is only a fraction of the size of its flagship brethren the RBPi, and less expensive as well. Almost identical to the RBPi Zero, the RBPiZW is twice as expensive, and boasts of a wireless chip supporting the 802.11 b/g/n Wi-Fi for Read more [...]

Lichee Pi – Another Contender for the Raspberry Pi

If you are looking for an alternative to the ubiquitous Raspberry Pi (RBPi), check out the Lichee Pi Zero. The basic board costs only $6.00 and another two dollars will get you the Wi-Fi version. Powered by the Allwinner V35 CPU, it is even smaller than the RBPi Zero, and works with the latest Linux kernel 4.10. The crowdfunding campaign offers a huge range of accessories. The ARM-based processor on the Lichee Pi Zero, the Allwinner V35, is an ARM Cortex-A7 CPU. It has a maximum speed of 1.2 GHz, Read more [...]

Treat Yourself to a Raspberry Pi Zero W

The launch of the Raspberry Pi Zero W (RBPiZW) by the Raspberry Pi Foundation recently has added two features many fans of the RBPi have been requesting for a long time. The two features, built-in Wi-Fi and Bluetooth, added to the wonderful RBPi Zero have improved the functionality of the tiny single board computer. After all, the RBPiZW is only a variant of the RBPi Zero, and therefore, does not merit a full length, in depth review. However, we will focus on the new features the RBPiZW brings Read more [...]

PiRyte Mini ATX PSU: Power Your Raspberry Pi

Powering the Single Board Computer, the Raspberry Pi (RBPi) is always simple using the wall-wart type power supply and the micro-USB cable. However, there is always the possibility of accidentally shutting off power to the RBPi without going through the proper shutdown sequence. As the RBPi relies on its micro SD card to store its Operating System and working files, a sudden loss of power is sure to corrupt them and render the RBPi incapable of rebooting in the next session. Additionally, you Read more [...]
