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 [...]

How Vulnerable is your Raspberry Pi

The IoT revolution has brought with it many Internet-connected computing devices, including several Single Board Computers, such as the Raspberry Pi (RBPi), going beyond the traditional mobile devices, laptops, desktops, and servers. It is common to see on the network devices such as Internet radio, refrigerators, thermostats, DVRs, and TVs, apart from SBCs such as the RBPi. As projects rush towards completion, Internet security is ignored, resulting in severe consequences—this is applicable Read more [...]

NanoPI NEO Challenges the Raspberry Pi

If you were looking for Raspberry Pi (RBPi) alternative, the NanoPi NEO would be a good fit. For a starting price of about $7, and measuring just 1.6x1.6 inches, it is smaller than the smallest RBPi Zero W, and is equally capable of running Linux. At its basic price, the RAM it carries is 256 MB. However, for a couple of dollars more, there is another version available and it has 512 MB RAM on it. The best thing about this tiny challenger to the RBPiZW is the bunch of accessories available. This Read more [...]

Orange Pi 2G-IoT Challenges the Raspberry Pi

If you are looking for an alternative for the ubiquitous Raspberry Pi (RBPi) or one of its siblings, give the Orange Pi 2G-IoT a second look. The Shenzhen-based maker of the Orange Pi developer board has made this one to rival the RBPiZW, the RBPi Zero W. The Orange Pi 2G-IoT is a new design for a single board computer, available for sale of AliExpress. The device can run Android, Debian, Ubuntu, or Raspbian. It gives builders a 2G antenna to run applications for the Internet of Things, and that 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 [...]

Orange Pi Prime – Another Rival for the Raspberry Pi 3

There is another Orange Pi among the branches of the highly productive Orange Pi tree belonging to Shenzhen Xunlong. This is the Orange Pi Prime—another rival to the most popular Raspberry Pi 3 (RBPi3). According to the year-end Linux hacker SBC roundup, half a dozen individual Orange Pi models were already existing, and if all the new variants are to be included, that number almost doubles. Proceeding at this rate, the company’s engineers will have checked out almost all possible combinations Read more [...]
