Keebin’ With Kristina: The One With The MingKwai Typewriter

Sometimes, a little goes a long way. I believe that’s the case with this tiny media control bar from [likeablob] that uses an ESP32-C3 Super Mini.

From left to right you’ve got a meta key that allows double functions for all the other keys. The base functions are play/pause, previous track, and next track while the knob handles volume.

And because it uses this Wi-Fi-enabled microcontroller, it can seamlessly integrate with Home Assistant via ESPHome.

What else is under the hood? Four low-profile Cherry MX Browns and a rotary encoder underneath that nicely-printed knob.

If you want to build one of these for yourself, all the files are available on GitHub including the customizable enclosure which [likeablob] designed with OpenSCAD. Continue reading “Keebin’ With Kristina: The One With The MingKwai Typewriter”

Hackaday Podcast Episode 320: A Lot Of Cool 3D Printing, DIY Penicillin, And An Optical Twofer

This week, Hackaday’s Elliot Williams and Kristina Panos met up across the universe to bring you the latest news, mystery sound, and of course, a big bunch of hacks from the previous week.

In Hackaday news, the 2025 Pet Hacks Contest rolls on. You have until June 10th to show us what you’ve got, so head over to Hackaday.IO and get started today!

On What’s That Sound, Kristina actually got it this time, although she couldn’t quite muster the correct name for it, however at Hackaday we’ll be calling it the “glassophone” from now on. Congratulations to [disaster_recovered] who fared better and wins a limited edition Hackaday Podcast t-shirt!

After that, it’s on to the hacks and such, beginning with a complete and completely-documented wireless USB autopsy. We take a look at a lovely 3D-printed downspout, some DIY penicillin, and a jellybean iMac that’s hiding a modern PC. Finally, we explore a really cool 3D printing technology, and ask what happened to typing ‘www.’.

Check out the links below if you want to follow along, and as always, tell us what you think about this episode inĀ the comments!

Keebin’ With Kristina: The One With The Bobblehead

No, see, it’s what’s inside that counts. Believe it or not, [nobutternoparm] retrofitted this innocent, adorable little tikesĀ® so-called “Kidboard” rubber-dome keyboard into a mechanical marvel. Yeah! No, it wasn’t exactly pure, unadulterated fun, nor was it easy to do. But then again nothing worth doing ever is.

For one thing, the PCB ended up being a bit too wide, so the bottom half of the case is a bit mangled. But that’s okay! Onward and upward.

Next problem: a real PCB and mechanical switches (Gateron Baby Kangaroos) are a lot taller than the previous arrangement. This required spacers, a mounting plate, and longer screws to hold it all together. Now imagine lining all that up and trying to keep it that way during assembly.

And then there’s the keycaps. Guess what? They’re non-standard because they’re for rubber domes. So this meant more adapters and spacers. You’ll see in the gallery.

So we know it looks great, but how does it type? Well… [nobutternoparm] gives the feel a 4/10. The keycaps now have too many points of contact, so they bind up and have to be mashed down. But it’s going to be a great conversation piece.

Keebin’ With Kristina: The One With The Protractor Keyboard

Don’t you love it when the title track is the first one on the album? I had to single out this adjustable keyboard called the Protractor, because look at it! The whole thing moves, you know. Go look at the gallery.

If you use a true split, even if you never leave the house, you know the pain of losing the good angle and/or separation you had going on for whatever reason. Not only does this monoblock split solve that simply by being a monoblock split, you can always find the right angle you had via the built-in angle finder.

[BFB_Workshop] used a nice!nano v2, but you could use any ZMK-supported board with the same dimensions. This 5 x 12 has 60 Gateron KS-33 switches, which it was made for, and has custom keycaps. You can, of course, see all the nice, neat ribbon cable wiring through the clear PLA, which is a really great touch.

This bad boy is flat enough that you can use the table as your palm rest. To me, that doesn’t sound so comfortable, but then again, I like key wells and such. I’d still love to try a Protractor, because it looks quite interesting to type on. If you want to build one, the files and instructions are available on Printables.

Keebin’ With Kristina: The One With The Part Picker

If you do a lot of 3D computer work, I hear a Spacemouse is indispensable. So why not build a keyboard around it and make it a mouse-cropad?

That’s exactly what [DethKlawMiniatures] did with theirs. This baby is built with mild steel for the frame, along with some 3D-printed spacers and a pocket for the Spacemouse itself to live in.

Those switches are Kailh speed coppers, and they’re all wired up to a Seeed Xiao RP2040. [DethKlawMiniatures] says that making that lovely PCB by hand was a huge hassle, but impatience took over.

After a bit of use, [DethKlawMiniatures] says that the radial curve of the macro pad is nice, and the learning curve was okay. I think this baby looks fantastic, and I hope [DethKlawMiniatures] gets a lot of productivity out of it.

Reader [akavel] was kind enough to notify me about Clawtype, which is a custom wearable chorded keyboard/mouse combo based on the Chordite by [John W. McKown].

First of all, I love the brass rails — they give it that lovely circuit sculpture vibe. This bad boy was written in Rust and currently runs on a SparkFun ProMicro RP2040 board. For the mouse portion of the program, there’s an MPU6050 gyro/accelerometer.

[akavel]’s intent was to pair it with XR glasses, which sounds like a great combination to me. While typing is still a bit slow, [akavel] is improving at a noticeable pace and does some vim coding during hobby time.

In the future, [akavel] plans to try a BLE version, maybe even running off a single AA Ni-MH cell, and probably using an nRF52840. As for the 3D-printed shape, that was designed and printed by [akavel]’s dear friend [Cunfusu], who has made the files available over at Printables. Be sure to check it out in the brief demo video after the break.

Keebin’ With Kristina: The One Where We Embrace The Jank

Yeah, yeah — not a keyboard. But one keyboard-adjacent topic I’m certainly interested in is that of finding a satisfying mouse. Why settle for ticky micro-switches when you could have full-on thock in both peripherals?

My own personal peripherals. Banana mat for scale.

I’ve been using a Logitech Ergo M575 for a couple of years now. As you can see, it’s a trackball with two extra buttons, which come programmed for forward and back. I find this next to useless, so I employed AutoHotKey and changed them to Ctrl+C on the up switch, and Ctrl+V on the down switch.

[Aknup] commented on the previous Keebin’ and brought up MMO mice, which, I didn’t know those things had a name other than maybe ‘multi-button mice’. And yes, there are a few trackball MMOs out there. I’ve got my eye on a couple already.

Does anyone have a trackball MMO? I hate to spend $100+ on something I won’t like. I’m intrigued that the one I found that’s the most attractive is less a thumb trackball and more a two-fingers-at-once kind of situation. That will take some getting used to, but the way my trackball moves sometimes, it could be a really positive change.
