Do you consider your keyboard to be a fragile thing? Meet the glass keyboard by [BranchNo9329], which even has a glass PCB. At least, I think the whole thing is glass.

The back side of an all-glass keyboard. Yeah. — Image via [BranchNo9329] via reddit

There are so frustratingly few details that this might as well have been a centerfold, but I thought you all should see it just the same. What we do have are several pictures and a couple of really short videos, so dive in.

I can tell you that [BranchNo2939] chose a glass substrate mainly due to curiosity about its durability compared with FR4. And that the copper circuitry was applied with physical vapor deposition (PVD) technology.

Apparently one of [BranchNo2939]’s friends is researching the bonding of copper on to glass panels, so they thought they’d give a keyboard a go. Right now the thing is incomplete — apparently there’s going to be RGB. Because of course there’s going to be RGB. Continue reading “Keebin’ With Kristina: The One With The Grasshopper Typewriter” →

Keebin’ With Kristina: The One With The Cheesy Keyboard

March 18, 2025 by Kristina Panos 4 Comments

Let’s just kick things off in style with the fabulously brutalist Bayleaf wireless split from [StunningBreadfruit30], shall we? Be sure to check out the wonderful build log/information site as well for the full details.

Here’s the gist: this sexy split grid of beautiful multi-jet fusion (MJF) keycaps sits on top of Kailh PG1316S switches. The CNC-machined aluminium enclosure hides nice!nano boards with a sweet little dip in each one that really pull the keyboard together.

For the first serious custom build, [StunningBreadfruit30] wanted a polished look and finish, and to that I say wow, yes; good job, and nod enthusiastically as I’m sure you are. Believe it or not, [StunningBreadfruit30] came into this with no CAD skills at all. But it was an amazing learning experience overall, and an even better version is in the works.

I didn’t read the things. Is it open-source? It’s not, at least not at this time. But before you get too-too excited, remember that it cost $400 to build, and that doesn’t even count shipping or the tools that this project necessitated purchasing. However, [StunningBreadfruit30] says that it may be for sale in the future, although the design will have an improved sound profile and ergonomics. There’s actually a laundry list of ideas for the next iteration. Continue reading “Keebin’ With Kristina: The One With The Cheesy Keyboard” →

Keebin’ With Kristina: The One With The Batwing Typewriter

March 11, 2025 by Kristina Panos 8 Comments

[Alex] of YouTube channel [EastMakes] wrote into tell me about his fantastic QWERTY ‘hexpansion’ board for the 2024 EMF Tildagon badge, and [Alex], I’m super glad you did. The system works!

Let’s back up a bit. Essentially, the idea is to have a badge that can be used beyond a single camp, with the creation of expansion boards being the other main attraction. Our own [Jenny List] covered the badge in detail back in June 2024 when she got her hands on one.

[Alex] started by importing the Tildagon into Fusion360 and designing a way for the keyboard to attach to it physically. He then modeled the keyboard after the Blackberry types that can be found on Ali using the official EMF buttons established in earlier badges.

This QWERTY hexpansion is based on the RP2040, which is soldered around back and visible through the 3D-printed backplate. In order for the 90°-oriented board to align with the… not-90° connector, [Alex] built a little meander into the PCB.

The default OS on the Tildagon doesn’t know natively what to do with the serial messages from the keyboard, so [Alex] wrote an application that reads them in and decodes them. Be sure to check out the build and walk-through video after the break.

A 3D-printed, hand-cranked, toy conveyor belt designed after the transporter belts in Factorio.

Designing A Toy Conveyor Belt For Fun And Profit

March 5, 2025 by Kristina Panos 5 Comments

[Hope This Works] wants to someday build a tiny factory line in the garage, with the intent of producing some simple widget down the line. But what is a tiny factory without tiny conveyor belts? Not a very productive one, that’s for sure.

As you may have noticed, this is designed after the transporter belts from the game Factorio. [Hope This Works] ultimately wants something functional that’s small enough to fit in one hand and has that transporter belt aesthetic going. He also saw this as a way to level up his CAD skills from approximately 1, and as you’ll see in the comprehensive video after the break, that definitely happened.

And so [Hope This Works] started by designing the all-important sprockets. He found a little eight-toothed number on McMaster-Carr and used the drawing for reference. From there, he designed the rest of the parts around the sprockets, adding a base so that it can sit on the desk or be held in the hand.

For now, this proof-of-concept is hand-cranked. We especially love that [Hope This Works] included a square hole for the crank handle to stand in when not in use. Be sure to check out the design/build video after the break to see it in action.

How happy would you be to see Factorio come up in a job interview?

Choc switches on a ThumbsUp! v8 keyboard with IBM Selectric typewriter keycaps, thanks to some 3D-printed adapters. — Image by [Sasha K.] via reddit

Remember that lovely Hacktric centerfold from a couple Keebins ago with the Selectric keycaps? Yeah you do. Well, so does [Sasha K.], who saw the original reddit post and got inspired. [Sasha K.] has more than one IBM Selectric lying around, which is a nice problem to have, and decided to strip one of its keycaps and get to experimenting.

The result is a nice adapter that allows them to be used with Kailh chocs — you can find the file on Thingiverse, and check out the video after the break to see how they sound on a set of clicky white chocs.

Those white chocs are attached to a ThumbsUp! v8 keyboard, a line that [Sasha K.] designed. His daily driver boards are on v9 and v10, but the caps were getting jammed up because of the spacing on those. So instead, he used v8 which has Cherry MX spacing but also supports chocs.

As you can see, there is not much to the adapter, which essentially plugs the Selectric keycap’s slot and splits the force into the electrical outlet-style pair of holes that chocs bear This feels like an easier problem to solve than making an adapter for MX-style switches. What do you think?

Hackaday Podcast Episode 310: Cyanotypes, Cyberdecks, And The Compass CNC

February 28, 2025 by Kristina Panos 4 Comments

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

First up in the news, and there’s a lot of it: we announced the Hackaday Europe 2025 workshops and a few more speakers, though the big keynote announcement is still to come. In case you missed it, KiCad 9 moved up into the pro league, and finally, we’re hiring, so come join us in the dungeon.

On What’s That Sound, Kristina didn’t get close at all, but at least had a guess this time. That’s okay, though, because nobody got it right! We’re still giving a t-shirt away to [Dakota], though, probably because Elliot has a thing for using random number generators.

Then it’s on to the hacks and such beginning with a beautiful handheld compass CNC and cyanotype prints made with resin printer’s UV light. After that, we take a look at open-source random numbers, a 3D-printed instant camera, and a couple of really cool cyberdecks. Finally, we discuss whether DOOM is doomed as the port of choice in this day and age, and kvetch about keyboards.

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

Keebin’ With Kristina: The One With All The Green Keyboards

February 24, 2025 by Kristina Panos 2 Comments

Okay, you have to see the gallery to appreciate it, but this keyboard was designed to resemble a red cedar tree with the green shell and wood bottom and the copper PCB showing through the tree cutouts on the sides.

But you know why I chose this picture — those PS2 buttons. According to [WesternRedCdar] they are just for fun, although they do allow for pressing Ctrl and Alt at the same time with a single thumb.

Oh, and are those Nintendo Switch joysticks above the PS2 buttons? Those are for the mouse and vertical/horizontal scrolling. Honestly, this seems like a great amount of thumb controls. The basics are there (presumably), and there isn’t any thumb-extending excess, like keys on the insides by the mouse.

This bad mama jama runs on an RP2040 and has 50 hand-wired Cherry Brown switches plus the PS2 buttons. In the build guide, you can read all about [WesternRedCdar]’s troubles with integrating those. The Nintendo Switch joysticks weren’t terribly easy, either, since the ribbon connector can’t be soldered directly.

The final issue was one of weight. Since many of the switches stand quite tall, it sort of jostles the keyboard to actuate them. [WesternRedCdar] opined that that the ideal solution would have been to use metal base plates instead of wood, but took care of the issue by adding layers of 1/8″ steel flat bar inside the case.
