This ‘computer mouse’ sets the new size standard for portable computing

The "Computer" Mouse: A DIY Project

You probably have a mouse for your computer, but do you have a computer mouse? One enterprising bedroom hardware hacker has managed to fit an entire laptop’s worth of components inside a mouse and has given it its own display. It’s a rather chunky device which wouldn’t pass muster in your average esports arena, but it’s an impressive feat of engineering nonetheless.

The mouse was created by YouTuber Electronic Grenade and is made from a 3D-printed mouse shell fitted around a Raspberry Pi Zero W. It’s connected to a 1.5-inch color OLED LCD display, a 500 mah battery, and all of the sensors and buttons you need to operate a standard two button mouse with scroll wheel. Better yet, it even has a pop-out miniature Bluetooth keyboard for text inputs and more complicated commands.

The micro-computer inside the mouse isn’t particularly capable, but can run basic text editing applications and apparently, when it’s feeling particularly good, Minecraft Pi Edition. Nothing about the project is practical, with typing and general icon selection hindered by the awkward position of the keyboard and the fact that the screen moves with the mouse. Not to mention its miniature form.

What’s impressive about the project, though, is that it does any of that at all. It’s entirely self-contained and is the smallest computing project that incorporates a full-size (or rather, a super-sized) mouse into the design we’ve ever come across.

This isn’t the first DIY project that Electronic Grenade has made, though. Previous home builds include turning an Xbox 360 into a stand-alone retro games console and a Raspberry Pi tablet. You may have stumbled across their videos in the past, though, through the vastly more popular project of turning a number of old CD-Rom drives into a DIY 3D printer.

But Electronic Grenade isn’t the only one who has made cool stuff out of Raspberry Pis and some ingenuity. There is a whole host of clever DIY builders and developers out there making exciting projects. Here’s our roundup of the best of them. If you’re wondering why they all use that particular micro-computer, here’s our look back on what made the Pi such a powerhouse despite its diminutive size.

New VESA display standard makes it easier to pick a monitor
Person using a gaming monitor.

Good news for those who want to buy a new monitor sometime soon -- a new specification has just come out that should make the whole process just a little bit easier.

The Video Electronics Standards Association (VESA) has just introduced a new motion blur spec, dubbed ClearMR. The standard will show at a glance whether or not a monitor excels in eliminating motion blur.

Metaverse giants form new standards to address lack of interoperability
An office meeting happening in the VR Metaverse.

Big-name tech companies such as Meta, Microsoft, and Epic Games have formed a standards organization called the Metaverse Standards Forum (MSF). This is meant to be a group that creates open standards for all things metaverse, including virtual reality, augmented reality, and 3D technology.

Over 30 companies have signed on, some of which are deep in metaverse technology like Meta itself. Others include Nvidia, Unity (the creators of the popular game engine), Qualcomm, Sony, and even the web standards organization itself -- the Worldwide Web Consortium (W3).

This half-sized portable monitor is unlike any you’ve ever seen
ASUS ProArt Display PA147CDV in use with touchscreen.

While portable monitors have been around for a few years now, Asus is showing off a new idea at the National Association of Broadcasters (NAB) Show. The Asus ProArt PA147CDV is a 14-inch portable panel with a few tricks up its sleeves. Unlike traditional portable screens, the PA147CDV comes with a more unique -- and narrow -- 1920 x 550 aspect ratio.

It's this intriguing aspect ratio that not only makes the PA147CDV stand out against the competition, but the narrow screen looks like it could have been ripped straight off of one of the company's many laptops with a secondary touch display.
