As much as I’d like to devote an article to each and every bit of keyboard-related what-have-you that I come across in my travels through the intertubes, there just aren’t enough hours. And after all, this isn’t Clack-a-Day. To that end, I gained editorial approval to bring you a periodic round-up of news and other tidbits on the keyboard and keyboard accessories front, and here we are. So let’s get to it!

While the price of electronic paper has dropped considerably over the last few years, it’s still relatively expensive when compared to more traditional display technology. Accordingly, we’ve seen a lot of interest in recovering the e-paper displays used in electronic shelf labels and consumer e-readers from the likes of Amazon, Barnes & Noble, and Kobo. Unfortunately, while these devices can usually be purchased cheaply on the second hand market, liberating their displays is often too complex a task for the average tinkerer.
Enter the Inkplate. With their open hardware ESP32 development board that plugs into the e-paper displays salvaged from old e-readers, the team at e-radionica is able to turn what was essentially electronic waste into a WiFi-enabled multipurpose display that can be easily programmed using either the Arduino IDE or MicroPython. The $99 Inkplate 6 clearly struck a chord with the maker community, rocketing to 926% of its funding goal on Crowd Supply back in 2020. A year later e-radionica released the larger and more refined Inkplate 10, which managed to break 1,000% of its goal.
For 2021, the team is back with the Inkplate 6PLUS. This updated version of the original Inkplate incorporates the design additions from the Inkplate 10, such as the Real-Time-Clock, expanded GPIO, and USB-C port, and uses a display recycled from newer readers such as the Kindle Paperwhite. These e-paper panels are not only sharper and faster than their predecessors, but also feature touch support and LED front lighting; capabilities which e-radionica has taken full advantage of in the latest version of their software library.
With its Crowd Supply campaign recently crossing over the 100% mark, we got a chance to go hands-on with a prototype of the Inkplate 6PLUS to see how e-radionica’s latest hacker friendly e-paper development platform holds up.
My son is growing up with computers. He’s in first grade, and had to list all of the things that he knows how to do with them. The list included things like mousing around, drawing ghosts with the paint program, and — sign of the times — muting and unmuting the microphone when he’s in teleconferences. Oh yeah, and typing emojis. He loves emojis.
When I was just about his age, I was also getting into computers. But home computers back then were in their early years as well. And if I look back, I’ve been getting more sophisticated about computers at just about the same pace that they’ve been getting more sophisticated themselves. I was grade school during the prime of the BASIC computers — the age of the Apple II and the C64. I was in high school for the dawn of the first Macs and the Amiga. By college, the Pentiums’ insane computational abilities just started to match my needs for them to solve numerical differential equations. And in grad school, the rise of the overclockable multi-cores and GPUs powered me right on through a simulation-heavy dissertation.
When I was a kid, they were playthings, and as a grownup, they’re powerful tools. Because of this, computers have never been intimidating. I grew up with computers.
But back to my son. I don’t know if it’s desirable, or even possible, to pretend that computers aren’t immensely complex for the sake of a first grader — he’d see right through the lie anyway. But when is the right age to teach kids about voice recognition and artificial neural networks? It’s a given that we’ll have to teach him some kind of “social media competence” but that’s not really about computers any more than learning how to use Word was about computers back in my day. Consuming versus creating, tweeting versus hacking. Y’know?
Of course every generation has its own path. Hackers older than me were already in high-school or college when it became possible to build your own computer, and they did. Younger hackers grew up with the Internet, which obviously has its advantages. Those older than me made the computers, and those younger have always lived in a world where the computer is mature and taken for granted. But folks about my age, we grew up with computers.
Hackaday’s Mike Szczys is taking a bit of vacation this week, so Elliot is joined by Staff Writer Dan Maloney to talk about all the cool hacks and great articles that turned up this week. Things were busy, so there was plenty to choose from, but how would we not pick one that centers around strapping a jet engine to your back to rollerskate without all that pesky exercise? And what about a light bulb that plays Doom – with a little help, of course. We’ll check out decals you can make yourself and why the custom keyboard crowd might want to learn that skill, learn about the other “first computer”, and learn how a little radiation might be just what it takes to save an endangered species.
Take a look at the links below if you want to follow along, and as always, tell us what you think about this episode in the comments!

First off, Apple has issued an update for some very old devices. Well, vintage 2013, but that’s a long time in cell-phone years. Fixed are a trio of vulnerabilities, two of which are reported to be exploited in the wild. CVE-2021-30761 and CVE-2021-30762 are both flaws in Webkit, allowing for arbitrary code execution upon visiting a malicious website.
The third bug fixed is a very interesting one, CVE-2021-30737, memory corruption in the ASN.1 decoder. ASN.1 is a serialization format, used in a bunch of different crypto and telecom protocols, like the PKCS key exchange protocols. This bug was reported by [xerub], who showed off an attack against locked iPhone immediately after boot. Need to break into an old iPhone? Looks like there’s an exploit for that now.

Land speed racing is one of the oldest forms of motorsport, and quite literally consists of going very, very fast in (ideally) a straight line. The higher the speed your car can attain, the better! It’s about the pure pursuit of top speed above all else, and building a car to compete is a calling for a dedicated few. If you’d like to join them, here’s how to go about it.
While taking the outright land speed record typically requires a jet-engined sled of singular design, there is plenty of land speed competition to be had in various classes for competitors fielding their own entries. There are vintage classes for older technology engines, still popular from the dawn of hotrodding, like Ford Flathead V8s and other contemporary motors. There are also classes split by engine displacement, number of cylinders, aerodynamic modifications, or the type of fuel used.
Racers often pick a record or set of records they wish to beat – for example, wanting to set the the fastest speed for a gasoline-powered, naturally-aspirated four cylinder – and build their car to that end. Alternatively, a racer might build a car with a large V8 engine, for example, to compete in one class, and then disable several cylinders on a later run to try and snatch records in lower classes as well.

If we were to think of a retrocomputer, the chances are we might have something from the classic 8-bit days or maybe a game console spring to mind. It’s almost a shock to see mundane desktop PCs of the DOS and Pentium era join them, but those machines now form an important way to play DOS and Windows 95 games which are unsuited to more modern operating systems. For those who wish to play the games on appropriate hardware without a grubby beige mini-tower and a huge CRT monitor, there’s even the option to buy one of these machines new: in the form of a much more svelte Pentium-based PC104 industrial PC.
