The good news is that more and more people are working from home these days. The bad news is that some of the more draconian employers out there aren’t too happy about it, to the point of using spyware software to keep tabs on their workers. Better make that bathroom break quick — Big Brother is watching!

One simple way to combat such efforts is a mouse jiggler, which does…well it does exactly what it sounds like. If you find yourself in need of such a device, the WorkerMouse from [Zane Bauman] is a simple open source design that can be put together with just a handful of components.

The WorkerMouse is designed to be assembled using through-hole parts on a scrap of perfboard, but you could certainly swap them out for their SMD variants if that’s what you have on hand. The circuit is largely made up out of passive components anyway, except for the ATtiny85 that’s running the show.

[Zane] decided to embrace modernity and couple the circuit with a USB-C breakout board, but naturally you could outfit it with whatever USB flavor you want so long as you’ve got a cable that will let you plug it into your computer.

The project’s C source code uses V-USB to connect to the computer and act as a USB Human Interface Device (HID). From there, it generates random speed and position data for a virtual mouse, and dumps it out every few seconds. The end result is a cursor that leaps around the screen whenever the WorkerMouse is plugged in, which should be enough to show you online while you step away from the computer. As an added bonus, [Zane] has put together a nice looking 3D printable enclosure for the board. After all, the thing is likely going to be sitting on your desk, might as well have it look professional.

If you’ve got the time to get a PCB made, you might also be interested in the MAUS we covered last year, which also keeps the ATtiny85 working so you don’t have to.

Even among ThinkPads, which are nearly universally loved by hardware hackers and Linux tinkerers alike, the 701c is a particularly rare and desirable machine. Best known for it’s “butterfly” slide out keyboard, the IBM-designed subnotebook from the mid-1990s has gained a following all its own, with active efforts to repair and restore any surviving specimens still out in the wild.

[polymatt] has already taken on a number of 701c restoration projects, but the recent release of a 3D printable case for the vintage laptop is arguably the most impressive to date. After spending an untold number of hours with an original case and a pair of calipers, the final design has been released under the Creative Commons Attribution-NonCommercial license — in other words, you’re free to print one to spruce up your 701c, but don’t run off a stack of them and start trying to move them on Etsy.

Originally, [polymatt] just wanted to 3D print a replacement for the laptop’s display bezel. But as often happens with these sort of projects, things just sort of started rolling and pretty soon the whole case was modeled. As you might imagine, the printed case has some slight differences between the original. For example, the printed version is designed to use heat set inserts. There’s also certain components, such as the hinges, which need to be sourced from an original case.

The most obvious use of these files is to perform repairs — if a piece of your 701c case has broken, you might be able to use one of these files to create a replacement. But it also offers some fascinating possibilities for future modifications. If you were planning on replacing the internals of the 701c with something more modern, these files would make an excellent starting point to create a customized case to better fit more modern components.

Whatever you end up doing with these files, don’t be shy — let us know.

We’ll admit to not fully knowing what [Jay Doscher] has planned for the pair of RTL-SDR Blog V4 software defined radios (SDRs) that are enclosed in the slick 3D printed enclosure he’s designed. But when has that ever stopped us from appreciating a nice design when we see one?

Inside the ventilated enclosure is the aforementioned pair of RTL-SDR Blog V4 (SDRs), as well as a StarTech USB hub that they’re plugged directly into. It seems like it wouldn’t take much to adapt this design to any other pair of USB gadgets, such as flash drives or WiFi adapters.

In fact, if they’re smaller than the RTL-SDR [Jay] has used here, you could probably get away with only needing to modify the one side panel of the case.

The simple modularity of the design, with two end pieces and the top and bottom plates, makes such modifications easy as you don’t need to reprint the whole thing if you just want a different antenna aperture. It also makes it easy to print without support material, and with just a few tweaks, looks like it could be adapted to use laser-cut panels for the sides. This would not only be faster than printing, but depending on the material, could make for a very stout enclosure.

We’ve covered several designs from [Jay] over the years, including a number of heavy-duty mobile “doomsday” computers that certainly fit in with this same design aesthetic. After all, why not face the end of the world with a little style?

Back in 2021, [stacksmashing] found that it took little more than a Raspberry Pi Pico and some level-shifters to create a USB connection with the Game Boy’s link port. Add in the proper software, and suddenly you’ve got online multiplayer for the classic handheld. The hardware was cheap, the software open source, and a good time was had by all.

Inspired by both the original project and some of the hardware variations that have popped up over the years, [weiman] recently set out to create a new version of the USB link adapter that fits inside a miniature 3D printed Game Boy.

The big change from the original design is that this is using the far smaller, but equally capable, RP2040-Zero development board. This is mated with a SparkFun logic level converter board (or a clone of one from AliExpress) by way of a custom PCB that also includes the necessary edge connectors to connect directly to a Game Boy Link Cable.

Once the PCB is assembled, it’s dropped into the 3D printed Game Boy shell. [weiman] really worked some nice details into the case, such as aligning the d-pad and buttons in such a way that pressing them engages either the RESET or BOOTSEL buttons on RP2040-Zero. The screen of the printed handheld also lines up with the RGB LED on the top of the dev board, which can produce some cool lighting effects.

The original project from [stacksmashing] was an excellent example of the capabilities of the Pi Pico, and we’re glad to see it’s still being worked on and remixed by others. Even though the state of Game Boy emulation is nearly perfect these days, there’s still something to be said for working with the original hardware like this.
