How to Use an RGB LED Module With Arduino - Make Tech Easier
Perhaps one of the most common modules in an Arduino starter kit, the RGB LED lets you create all sorts of colors with just four pins from the Arduino. This tutorial demonstrates two ways to use this module, so read on to learn how well it works!

Telnet Gets Stubborn Sony Camera Under Control
According to [Venn Stone], technical producer over at LinuxGameCast, the Sony a5000 is still a solid option for those looking to shoot 1080p video despite being released back in 2014. But while the camera is lightweight and affordable, it does have some annoying quirks — namely an overlay on the HDMI output (as seen in the image above) that can’t be turned off using the camera’s normal configuration menu. But as it so happens, using some open source tools and the venerable telnet, you can actually log into the camera’s operating system and fiddle with its settings directly.

When Pi Supply Falls Short, Thin Clients Stand Tall For Home Automation And Low Power Computing
Do you need a cheap, small computer for a low power computing project? Historically, of us would reach straight for a Raspberry Pi, even if we didn’t absolutely need the GPIO. But with prices elevated and supplies in the dumps, [Andreas Spiess] decided that it was time to look for alternatives to now-expensive Pi’s which you can see in the video below the break.

Hackaday Podcast 194: FPV Contest, Seven Words, Lots Of Coffee, And Edible Drones
This week, Editor-in-Chief Elliot Williams and Assignments Editor Kristina Panos fumbled through setting up Mumble on Kristina’s new-ish computer box before hitting record and talking turkey. First off, we’ve got a fresh new contest going on, and this time it’s all about the FPVs. Then we see if Kristina can stump Elliot once again with a sound from her vast trove of ancient technologies.

Create a holiday light display with your Raspberry Pi and ping pong balls
I love Christmas decorations and lights, and I'd been wanting to do an programmable LED project for a long time. Recently, I built a light array made of LED lights, ping pong balls, and a Raspberry Pi Zero. I thought it was worth sharing, because it ended up being relatively easy but also educational.
It's mostly my own design, with some inspiration from YouTube videos. You can find the source code and build instructions in my Git repository.

System76 tease the new Launch Heavy keyboard
They've put up a teaser website, which gives some of the details on what to expect from it. Just like the previous two models, it will be fully customizable with their open source Keyboard Configurator app. Considering the excellent build quality of the original Launch Keyboard that I reviewed, I have high hopes for this one and the full size is great.

The theremin is getting an open-source version, the Theremotion
The instrument is based on the Leap Motion Controller, an optical hand-tracking module that's able to map individual finger movements and more complicated hand gestures than the original theremin. Theremotion is an open-source project, available via [m$] GitHub, while the Leap Motion Controller is available for about $110.

Acorn RiscPC: Restoration Part 3
I mentioned in my previous post that I wanted to install a CF card based hard drive into this, eliminating the need for an old spinning-rust IDE drive. I tried for quite a while to get the following to work.
