A Better Raspberry Pi Streaming Solution

In the June 2016 issue, I described my Raspberry Pi outdoor camera build. Since then, however, I've discovered a different way to stream video from it. more>>

Build Your Own Raspberry Pi Camera

During the past few years, my BirdCam setup has evolved significantly. As I mention in the UpFront section of this issue, I hope to get the stream transferred to a YouTube Live stream at some point, so I can watch the feathery show on my television. And although watching the birds is the end goal, I'm constantly on a mission to improve the quality and flexibility of my setup. more>>

RPi-Powered pi-topCEED Makes the Case as a Low-Cost Modular Learning Desktop

It's hard to go a day without seeing interesting and compelling Indiegogo or Kickstarter projects that feature the Raspberry Pi, Pine 64 or the Intel Edison inside some sort of embedded device or standalone computer or laptop. Last fall, I stumbled across one such project that billed itself as "the first $99 Raspberry Pi desktop", and I felt the need to have it. more>>

Raspberry Pi 3

Four years ago (last leap day to be specific), the first Raspberry Pi was released. And on February 29, 2016, the third version made its debut. more>>

What's New in 3D Printing, Part IV: OctoPrint

This is the last article in a four-part series on the current state of 3D printing. In the first part, I gave an overall introduction to differences in 3D printing since I wrote my original articles on 3D printing three years ago. The second piece focused on advances in 3D printing hardware, and the third column covered 3D printing software. more>>

Raspberry Pi Gets OpenGL Support

The Raspberry Pi Foundation continues to push the limits of single-board computing. This month, it has added experimental OpenGL support to its Raspbian OS. more>>

Build a Large-Screen Command Center with the RPi 2

When the folks who make the Raspberry Pi made good on their plan to release a multi-core version of the tiny computer with 1GB of RAM earlier this year, I saw it as the perfect opportunity to put the single-board Linux box to work—real work—in our company's network operations center. more>>

Securi-Pi: Using the Raspberry Pi as a Secure Landing Point

Like many LJ readers these days, I've been leading a bit of a techno-nomadic lifestyle as of the past few years—jumping from network to network, access point to access point, as I bounce around the real world while maintaining my connection to the Internet and other networks I use on a daily basis. more>>

A Tasty Slice of Awesome

I love the flavor of raspberries, but quite honestly, the seeds gross me out. more>>

Home Automation with Raspberry Pi

The Raspberry Pi has been very popular among hobbyists and educators ever since its launch in 2011. The Raspberry Pi is a credit-card-sized single-board computer with a Broadcom BCM 2835 SoC, 256MB to 512MB of RAM, USB ports, GPIO pins, Ethernet, HDMI out, camera header and an SD card slot. more>>

Raspberry Pi competitor

Goodbye, Pi. Hello, C.H.I.P.

A new mini-computer is on the way, and it looks like it may be the Raspberry Pi killer we've all been waiting for (sorry Pi). C.H.I.P. is its name, and it looks set to wipe the floor with its established competitor on several counts:

1. It's completely open source. I don't just mean the software, either. more>>

Real-Time Rogue Wireless Access Point Detection with the Raspberry Pi

Years ago, I worked for an automotive IT provider, and occasionally we went out to the plants to search for rogue Wireless Access Points (WAPs). A rogue WAP is one that the company hasn't approved to be there. So if someone were to go and buy a wireless router, and plug it in to the network, that would be a rogue WAP. more>>

Raspi-Sump

In June 2013, we had the unfortunate luck of a basement flood, caused by a tripped electrical breaker connected to our sump pump. There are so many things that can go wrong with a sump pump. You always are on guard for power outages, blown breakers, sump pump failures, clogged pipes and all manner of issues that can arise, which ultimately can end with a flooded basement. more>>

Super Pi Brothers

I don't game as much as I used to. Although I've certainly spent countless hours of my life in front of a Nintendo, SNES, or after that, playing a first-person shooter on my computer (Linux only, thank you), these days, my free time tends to go toward one of the many nongaming hobbies I've accumulated. more>>

Two Pi R 2: Web Servers

In my last article, I talked about how even though an individual Raspberry Pi is not that redundant, two Pis are. I described how to set up two Raspberry Pis as a fault-tolerant file server using the GlusterFS clustered filesystem. more>>
