A $50 CNC via hack a day [Arduino]

In theory, there’s isn’t much to building a CNC machine. Hook a bit to a motor and move the motor around with some lead screws and stepper motors. Easy. But, of course, the devil is in the details. [DAZ] made a nice-looking and inexpensive rig that probably isn’t the most precise CNC in the world, but it looks like it does a good enough job and he claims he spent about $50 on it. The video below shows some of the work it has done, and it doesn’t look bad.

This isn’t a rainy afternoon project. You’ll need to cut some wood and 3D print many parts. The drives use M8 threaded rod. Electronics is just an Arduino running standard software.

Onion Pi makes your web traffic anonymous via Open Electronics

Hmmm, might be an easy (and relatively cheap) way to play around with Tor and learn a bit more about this anonymizing service. -- Douglas Adafruit’s Onion Pi is a Tor proxy that makes your web traffic anonymous, allowing you to use the internet free of snoopers and any kind of surveillance. Follow Adafruit’s tutorial on setting up Onion Pi and you’re on your way to a peaceful anonymous browsing experience. Tor is an onion routing service – every internet packet goes through 3 layers of relays before going to your destination. This makes it much harder for the server you are accessing (or anyone snooping on your Internet use) to figure out who you are and where you are coming from.

How to Build a Raspberry Pi-Powered Digital Photo Frame via Tom's Hardware

A digital photo frame is a small screen that can sit on your desk in your office or in your kitchen displaying your favorite pictures, changing at regular intervals. The first commercial digital photo frame was introduced in the 1990s shortly after the digital camera. Digital photo frames made a comeback in popularity during 2020, perhaps because people were staying at home more. In this tutorial, we’ll turn our Raspberry Pi into a digital photo frame using MagicMirror and the GooglePhotos module. Please note, we will skip installation of the 2-way mirror in the original Magic Mirror project. Consider this project, “Magic Mirror, without the mirror.” Read How to Build a Raspberry Pi-Powered Digital Photo Frame via Tom's Hardware An interesting link found among my daily reading

On my Mac/Windows PC…Disk Inventory X/WinDirStat

Disk Inventory X | WinDirStat There comes a time in every computer user's life when they need to figure out why their hard drive is out of space and Disk Inventory X and WinDirStat are a great help.
