Build your own Raspberry Pi 3 computing cluster Single-board-computers like the Raspberry Pi 3 are an inexpensive way to do all kinds of computing tasks, including supercomputing. The computers, ethernet switch, and cooling fans can be powered by a USB power supply. The example software to use is Einstein at Home. However one could use other kinds of software. The system design shown has a private network between 7 Raspberry Pi's all connected to the ethernet switch and an 8th RPI acting as a gateway to that network. By going through the process you learn details of configuring the Linux DHCP service, a NAT Router, and more.
Build your own security camera system with Raspberry Pi and cheap webcams You can build a powerful and flexible motion sensing security camera system using open source software on a Raspberry Pi and similar single board computers. The key is the MotionEyeOS that neatly bundles everything you need into a Raspberry Pi image. Simply burn it to an SD card, attach cameras, boot the Raspberry Pi, and start configuring. It easily supports monitoring multiple cameras, which can be USB webcams, WiFi cameras, the Raspberry Pi camera, or other MotionEyeOS instances. I have an original-version Raspberry Pi (low CPU power) driving two cameras and it handles things just fine.
How to back up your Raspberry Pi SD card, or copy it to another (larger?) Raspberry Pi SD card SD Cards aren't exactly the most reliable of data storage devices. What happens if you've put hundreds of hours of work into a Raspberry Pi system, it's all on your SD Card, and the card craps out. Have you saved your work? Or maybe you need to move to a larger SD Card because you've run out of space. Or maybe you want to duplicate the card to have additional systems. These tasks are pretty easy, but not intuitively obvious. It'll take some time at the command line, but fortunately the commands are easy.
Inexpensively stream your MP3 collection with Raspberry Pi and Pi MusicBox Why pay megabucks to buy a commercialized music streaming gizmo that requires a monthly fee? You may already have the MP3 files, and with the right software a simple computer like the Raspberry Pi is sufficient to stream the music anywhere on your home network. The Pi MusicBox software makes it incredibly easy to setup, the only wrinkle being to have a large enough storage device. Fortunately the Raspberry Pi can easily use a USB hard drive.
Installing OpenVPN on a Raspberry Pi Zero W, inexpensive security for your peace of mind Nowadays our personal privacy is being threatened by new government policies. Fortunately the open source world gives us tools with which to secure our lives. This tutorial goes over installing OpenVPN on your home network, giving you a secure method to access resources on your home network from anywhere else. Suppose you have a NAS with many terabytes of data at home, but you're traveling thousands of miles away and need to access that data. A VPN service on your home network provides a porthole through which to do so, provided you have VPN software on the computer you're carrying.
Raspberry Pi Zero W, inexpensive Zero goodness, now with WiFi for just $10 The original Raspberry Pi Zero was a game-changer for inexpensive computers, offering a full-fledged for just $5. The biggest problem was the lack of WiFi. The Raspberry Pi foundation have now fixed that, unveiling the new Zero W with both WiFi and Bluetooth.
Relive the glory days of Mac OS 7 on a Raspberry Pi Have fond memories of Mac OS 7 but unable to find an old Mac? With a simple Mac emulator, an inexpensive Raspberry Pi becomes a competent old-school Mac capable of running Mac OS 7. Oh, and all those old games. The video goes over what's involved, so have fun.
