Raspberry Pi Powers VR Headset for Mice | Tom's Hardware
The Raspberry Pi is an excellent tool for fun projects and hobbies, but it’s also a popular choice in professional fields. Such is the case with this project from the team at the Schaffer-Nishimura Lab (opens in new tab). Using a Raspberry Pi, they’ve constructed a custom VR headset (opens in new tab) to aid in their neuroscience research involving mice.
The headset is small enough to fit on the head of a mouse and features two SPI displays. These screens project a look into a custom world designed using the open-source Godot game engine. A custom map was created in the example pictures shown with a grid texture on the ground. It has cliffs, edges, and other obstacles that the mouse can encounter as needed for their neuroscience research.

Khadas Edge 2 Pro Review: Living on the Edge | Tom's Hardware
Khadas has a history in single board computers. The company makes high-spec, high cost boards that outperform the Raspberry Pi in almost every area. The Raspberry Pi may still hold the throne, but there are many challengers seeking to end its reign.
The Khadas Edge 2 Pro comes in two configurations, a Maker kit and an Arm PC kit. The Maker kit is the bare board which comes in a $199 model with 8GB of RAM and 32GB of eMMC 5.1 storage. For $100 ($299) more you can get the Pro version, with 16GB of RAM and 64GB of eMMC 5.1. The Arm PC version costs an additional $30 more and provides a rather lovely looking case. These prices are either side of the VIM 4 which weighs in at $239.

Raspberry Pi Remotely Controls Robot Guinea Pig Using SSH | Tom's Hardware
Practical Dad, as he’s known on YouTube, has earned his title thanks to projects like this Raspberry Pi-powered robotic guinea pig named K-V. The only thing this guinea pig eats is electricity, and he listens pretty well to commands. To spice things up a bit, he opted to add remote controls to the project using SSH as the primary communication platform.
If you’re not familiar with SSH, we have a few guides handy to help you get started. First, check out this guide by Les for detailed instructions on using SSH to connect to computers remotely—this guide works for Windows, macOS and Linux operating systems. We also have steps handy for setting up an SSH Key to keep the connections secure.

Alexa-Powered Side Table Mixes Drinks on Command
The video is a little light on the hardware details, but the folks at Hackster.io managed to spot a few components, including an Arduino Mega 2560 development board that controls pumping mechanisms, and servos that raise and lower dispenser nozzles.
