Keebin’ with Kristina: the One With the Typo Kristina Panos | usagoldmines.com

Ceci n’est pas une keyboard, sure. But it’s keyboard-adjacent, and how. [Joshua Bemenderfer]’s wrists are tired of moving off the keyboard in order to mouse, and he decided to create a trackball that can sit just below the Space bar. The idea is to get rid of the regular mouse entirely if this works out.

And sure, the Ploopy family of open-source mice would welcome him with open arms, but they don’t come cheap. [Joshua]’s plan here is to make something for under $10. Ideally, less than $5.

Starting with an off-the-shelf trackball, the first BOM came in around $25 if you throw in $5 for the 3D printing of the case. [Joshua] added some cheap ceramic bearings to make it better. Since this was still too high, he turned to the internals of cheap mice.

Trial and error has resulted in a 99-cent special from Ali being the idea candidate. There are even cheaper mice to be had, but this one has an ideal layout for doing a bit of surgery. It also requires remapping since [Joshua] is flipping the sensor upside down and using a POM ball on top of it. Now he just needs to figure out how to add buttons and make them split keyboard-friendly.

[crazymittens-r]’s Crazy ArcPedals Glow-Up

You may remember [crazymittens-r] from such keyboards as the ArcBoard, featured in Keebin’ a few months ago. There were pedals pictured as well, but the keyboard out-shined them at the time. Well, not anymore.

Holding down keys like Shift brings fiery pain and/or numbness to [crazymittens-r]’s arms, hands, and fingers that is brutally annoying, so the idea is to offload all possible duties to the feet. After all, they’re just sitting there doing nothing. Isn’t it time you put your feet to work for you?

With eight buttons per foot, per-key LEDs with RGB indicators, and a reportedly very comfy foot perch, what more could you want? Even so, [crazymittens-r] warns that although you can build MK3, you should probably wait for MK4.

Having tried to solve the foot keyboard problem myself, I can attest that that the real challenge is twofold: you need buttons that are comfortable for foot actuation, and they need to be located in comfortable places. And mounting them at roughly 90° to the floor isn’t the answer, either, but I was working with a cheap step stool, not an awesome 3D-printed scratch build. If you could benefit from pedals at all (and you probably can), then consider giving these a go. I can’t even imagine how cool MK4 are going to look.

The Centerfold: This Thicc Work Setup

Even the wrist rest. So that there is an IBM 5251 beam spring keyboard that is now controlled via QMK. (Here’s what a beam spring sounds like, BTW. Be sure to stick around for the part where the solenoid is on!) Note the Radio Shack poster, which [Kenwood1994] says is for the CoCo 1.

Historical Clackers: the Typo Is Basically a Mystery

According to The Antikey Chop, nothing is known about this cast iron and steel typewriter aside from what is possible to deduce from its physical characteristics. Not the year it was created, not the make, nor the origin. (Presumably, Typo is the model.)

This is an index typewriter, which means it works like an old embossing labelmaker, although the index itself is missing in this specimen. The matching dare-I-call-it daisy wheel type element is also missing here. Also sadly absent are the wood base it was mounted to, which bore a faux alligator skin top.

In order to type, the disc pivots toward the platen. Instead of spinning the brass arrow to select the character, you would turn that knob on the left. The three keys are for spacing, carriage release, and printing. The machine used an inked ribbon.

There is a second known version of this typewriter branded the Popular. The two are slightly different, and it is theorized that the Popular came first. The Antikey Chop’s theory is that these machines originated in Europe, but not England. Maybe Spain because of the way “Popular” is spelled.

This Typo might have been a German export as it was found in Germany, and “patent” is spelled as it would be in a German text.

ICYMI: Portable Computer Looks Good with Wood

We’ve seen our fair share of cyberdecks and portable computers over the years. Most are some form of plastic, and this one is no exception, having been built into a sturdy plastic case. But the difference here is in the addition of wooden panels.

In the video, [DIY Tinkerer] starts off with the guts, deciding to build the thing around the familiar Raspberry Pi 4. This is married up with a 9000 mAh battery, plus a power jack on the front allows it to run on 5 V – 20 V DC. Rounding things out is a multi-memory card reader and a handful of USB 3 ports.

Most of the video focuses on the build itself, including the woodworking bits and fitting everything into that rugged plastic shell.  Probably the coolest thing about this whatever-you-want-to-call-it is the built-in oscilloscope; that’s gonna come in handy more than you think.

Got a hot tip that has like, anything to do with keyboards? Help me out by sending in a link or two. Don’t want all the Hackaday scribes to see it? Feel free to email me directly.
