Cheap Writing Deck Eschews Distractions

February 20, 2026 by 4 Comments

A modern computer can be a great productivity tool. It can also be a great source of distractions. To solve that issue, [Quackieduckie] built the e-typer—a device for writing without distraction.

[Quackieduckie] refers to the device as a “low-cost e-ink typewriter” which lays out the basic mode of operation. It consists of a 4.2 inch e-ink screen, combined with an Orange Pi Zero 2W running the Armbian operating system. It’s set up to boot straight into a document editor so there’s no messing around with other software that could get in the way of productivity. The components are all wrapped up in a tidy 3D printed housing, which includes a foldable stand so you can prop the screen up wherever you happen to be working. [Quackieduckie] built the device to work with any USB-C keyboard, probably figuring that those eager to maximize productivity will already have the typing device of their dreams on hand. Code for the project is available on GitHub for those eager to replicate the build.

We’ve featured similar builds in the past, often referred to as “writing decks.” They’re becoming increasingly popular as people look for distraction-free, ad-free tech experiences. A great example is this clamshell design with an integrated keyboard. If you’re building your own productivity aids in your home lab, don’t hesitate to notify the tipsline!

The Joy Of Making Handheld Tetris From Scratch

February 19, 2026 by No comments

As anyone who’s made a thing knows, a lot of work goes into bringing something from idea to completion. But there’s also considerable satisfaction in the process. [Willian] recently did exactly that, and shares the joyful experience of creating a homebrew handheld game gadget from scratch. It runs a homebrewed Tetris clone (as well as Snake), and we love the results.

The game gadget uses an ATmega328P programmed via the Arduino IDE, and a 1.8″ TFT color LCD screen. It’s self-contained in a box with a few buttons as controls and runs off three AAA cells. [Willian] made the smart design choice to run the microcontroller at 8 MHz instead of the more common 16 MHz, because doing so meant the board can run at 3.3 V instead of 5 V. Why does this matter? The LCD display runs off 3.3 V as well, and if all components can run off the same supply and logic levels, it simplifies things considerably.

Also, creating a 3.3 V supply is a simple matter of three alkaline cells in series with an LDO (low drop-out) regulator, which is great for a handheld device. We do note that AA cells have a considerably higher energy density and capacity than AAA cells and are usually the better choice, but one works with what one has, and sometimes the space and weight saved by AAA is just too good to pass up.

The software has some notable approaches to keep things responsive and optimal. Instead of defining each of the Tetris pieces as a 2D shape, [Willian] instead pre-defines each piece (and their rotations) so that rotating a piece is just an index change in an array, instead of a transform implementing a rotation. Also, full-screen redraws are comparatively slow over SPI and caused flickering, so only cells that have changed are redrawn to the screen to keep things responsive. The code is all on GitHub, and it’s a great peek at how things get implemented under the hood.

The enclosure is just cardboard, and it does the job in [Willian]’s case. But we’ll point out that cardboard is actually a highly adaptable material from which to prototype. With just a few tips and a little care, paper products can be your new best friend when it comes to one-offs and prototypes.

Microsoft Uses Plagiarized AI Slop Flowchart To Explain How Git Works

February 19, 2026 by 14 Comments

It’s becoming somewhat of a theme that machine-generated content – whether it’s code, text or graphics – keeps pushing people to their limits, mostly by how such ‘AI slop’ is generally of outrageously poor quality, but as in the case of [Vincent Driessen] there’s also a clear copyright infringement angle involved. Recently he found that Microsoft had bastardized a Git explainer graphic which he had in 2010 painstakingly made by hand, with someone at Microsoft slapping it on a Microsoft Learn explainer article pertaining to GitHub.

As noted in a PC Gamer article on this clear faux pas, Microsoft has since quietly removed the graphic and replaced it with something possibly less AI slop, but with zero comment, and so far no response to a request for comment by PC Gamer. Of course, The Internet Archive always remembers.

What’s probably most vexing is that the ripped-off diagram isn’t even particularly good, as it has all the hallmarks of AI slop graphics: from the nonsensical arrows that got added or modified, to heavily mutilated text including changing ‘Time’ to ‘Tim’ and ‘continuously merged’ into ‘continvuocly morged’. This makes it obvious that whoever put the graphic on the Microsoft Learn page either didn’t bother to check, or that no human was involved in generating said page.

With the ESP32-P4 not having any wireless functionality and instead focusing on being a small SoC, it makes sense to combine it with a second chip that handles features like WiFi and Bluetooth. This makes the Guition ESP32-P4-M3 module both a pretty good example of how the P4 will be used, and an excellent opportunity to tear into, decap and shoot photos of the dies of both the P4 and the ESP32-C6 in this particular module, courtesy of [electronupdate]. There also the blog post for those who just want to ogle the shinies.

After popping the metal shield on the module, you can see the contents as in the above photo. The P4 inside is a variant with 32 MB of PSRAM integrated along with the SoC die. This results in a die shot both of this PSRAM and the P4 die, though enough of the top metal seems to remain to clearly see the latter.

The Boya brand Flash chip is quite standard inside, and along with a glance at the inside of one of the crystal oscillators we get to glance at the inside of the C6 MCU. This is a much more simple chip than the P4, with the RF section quite obvious. The total die sizes are 2.7 x 2.7 mm for the C6 and 4.29 x 3.66 mm for the P4.

RP2040 Powers A MIDI-Controlled Soundboard

February 19, 2026 by No comments

When you’re livestreaming, it can be tempting to fire off all kinds of wacky sound effects like you’re a morning radio DJ back in the heady days of 1995. If that’s who you want to be, you might like this soundboard project from [Biker Glen].

The build is based around an RP2040 microcontroller. It’s paired with an I2S digital-to-analog converter for sound output, which in turn feeds a small amplifier hooked up to a speaker or a line output.  The RP2040 is programmed to respond to MIDI commands by playing various sounds in response, which are loaded off a microSD card. It’s able to act as a USB MIDI host, which allows it to work seamlessly with all sorts of off-the-shelf MIDI controllers like the MIDI Fighter or the Novation Launchpad.

It’s an interesting hardware solution to a problem that you could probably also solve with software on your streaming machine, especially if you’ve already got a USB MIDI controller. However, there’s something to be said for lightening the load when your streaming computer is already doing lots of hard work to truck video up to the cloud already. Files are on Github if you’re eager to replicate the build.

Soundboards are just fun, which is why we’ve featured them before. Meanwhile, if you’re whipping up your own streaming accessories at home, be sure to let us know on the tipsline!

Fixing A Destroyed XBox 360 Development Kit

February 19, 2026 by 3 Comments

As common as the Xbox 360 was, the development kits (XDKs) for these consoles are significantly less so. This makes it even more tragic when someone performs a botched surgery on one of these rare machines, leaving it in dire straits. Fortunately [Josh Davidson] was able to repair the XDK in question for a customer, although it entailed replacing the GPU, CPU and fixing many traces.

The Xbox 360 Development Kit is effectively a special version of the consumer console — with extra RAM and features that make debugging software on the unit much easier, such as through direct access to RAM contents. They come in a variety of hardware specifications that developed along with the game console during its lifecycle, with this particular XDK getting an upgrade to being a Super Devkit with fewer hardware restrictions.

Replacing the dead GPU was a new old stock Kronos 1 chip. Fortunately the pads were fine underneath the old GPU, making it easy to replace. After that various ripped-off pads and traces were discovered underneath the PCB, all of which had to be painstakingly repaired. Following this the CPU had apparently suffered heat damage and was replaced with a better CPU, putting this XDK back into service.

The History Of The View-Master

February 19, 2026 by 8 Comments

We are going to bet that as a kid, you had a View-Master. This toy has been around for decades and is, more or less, a handheld stereoscope. We never thought much about the device’s invention until we saw a recent video from [View Master Travels and Peter Dibble]. It turns out that the principle of the whole thing was created by the well-known [Charles Wheatstone]. However, it was piano repairman [William Gruber] who invented what we think of as the View-Master.

[Gruber] didn’t just work on normal pianos, but complex player pianos and, in particular, the pianos used to record player piano rolls. He was also, as you might expect, a stereo photography enthusiast. Many of the ideas used in automating pianos would show up in the View-Master and the machines that made the reels, too. In the 1930s, stereoscopes were not particularly popular and were cumbersome to use. Color film was also a new technology.
