[Jean] wrote into the tips line (the system works!) to let all of us know about his hacked and hand-wired C64 keyboard, a thing of beauty in its chocolate-brown and 9u space bar-havin’ glory.
Image by [Jean] via GitHubThis Arduino Pro Micro-based brain transplant began as a sketch, and [Jean] reports it now has proper code in QMK. But how is a person supposed to use it in 2025, almost 2026, especially as a programmer or just plain serious computer user?
The big news here is that [Jean] added support for missing characters using the left and right Shift keys, and even added mouse controls and Function keys that are accessed on a layer via the Shift Lock key. You can see the key maps over on GitHub.
I’ll admit, [Jean]’s project has got me eyeing that C64 I picked up for $12 at a thrift store which I doubt still works as intended. But don’t worry, I will test it first.
Fortunately, it looks like [Jean] has thought of everything when it comes to reproducing this hack, including the requisite C64-to-Arduino pinout. So, what are you waiting for?
ArcBoard MK20 Proves That Nothing Is Ever Finished
I find it so satisfying that [crazymittens-r] is never quite satisfied with his ArcBoard, which is now in its 20th revision.
Image by [crazymittens-r] via redditWhen asked ‘WTF am I looking at?’, [crazymittens-r] responded thusly: ‘my interpretation of how you might use a keyboard and trackball without moving your hands.’ Well, there you have it.
This is one of those times where the longer you look, the crazier it gets. Notice the thumb trackball, d-pad thingy, and the green glowy bit, all of which move. Then there are those wheels up by the YHN column.
A bit of background: [crazymittens-r] needed something to help him keep on working, and you know I can relate to that 100%. There’s even a pair of pedals that go with it, and you’ll see those in the gallery.
You may remember previous ArcBoards, and if not, know this: it’s actually gotten a lot smaller since mk. 19 which I featured here in May 2024. It still looks pretty bonkers in the best possible way, though, and I’m here for it.
Image by [harrael] via redditSo I have become fond of finding fuller-figured centerfolds for you such as KaSe by [harrael]. As the top commenter put it, KaSe gives off nice Esrille NISSE vibes. Boy howdy. And I think that’s probably just enough thumb keys for me.
[harrael] had noble goals for this project, namely learning more about ESP32-S3s, USB/BLE HID, and firmware design, but the most admirable of all is sharing it with the rest of us. (So, if you can’t afford a NISSE…)

I’m going to take a brief detour from the normal parade of old typewriters to feature Typewriter Tom, who has so many machines lying around that Hollywood regularly comes knocking to borrow his clacking stock.
And how many is that? Around 1,000 — or six storage units full. Tom received a call once. The caller needed six working IBM Selectrics ASAP. Of course, Tom could deliver, though he admits he’s probably the one person in all of Georgia who could.
Another thing Tom delivers is creativity in the form of machines he sells to artists and students. He also co-founded the Atlanta Typewriter Club, who have been known to hold typewriter petting zoo events where people can come and — you guessed it — put their hands on a typewriter or two.
Go for the story and stay for the lovely pictures, or do things the other way around if you prefer. But Typewriter Tom deserves a visit from you, even if he already got one from Tom Hanks once.
Finally, PropType AR Can Turn Anything Into a Keyboard
Yes, literally anything with enough real estate can now become a keyboard, or at least it would seem from TechExplore and the short video embedded below. Watch as various drinking vessels and other things become (split!) keyboards, provided you have your AR goggles handy to make the magic happen.
Image by [PropType] via YouTubeWhile this setup would be immensely helpful to have around given the right circumstances, the chances that you’re going to have your AR goggles on you while running or running around the mall seem somewhat slim.
But the point here is that for augmented reality users, typing is notoriously difficult and causes something known as ‘gorilla arm’ from extended use. So in all seriousness, this is pretty cool from a problem-solving standpoint.
So how does it work? Basically you set the keyboard up first using the PropType editing tool to customize layouts and apply various effects, like the one you’ll see in the video. Be sure to stick around for the demo of the editing tool, which is cool in and of itself. I particularly like the layout on the soda can, although it might be difficult to actually use without spilling.
[joppedc] wrote in to let us know that the Formula 1® season is coming to an end, and that the final race should be bangin’. To get ready, he built this ultra-sleek logo light box last week that does more than just sit there looking good, although it does that pretty well. This light box reacts to live race events, flashing yellow for safety cars, red for red flags, and green for, well, green flags.
The excellent light box itself was modeled in Fusion 360, and the files are available on MakerWorld. The design is split into four parts — the main body, a backplate to mount the LEDs, the translucent front plate, and an enclosure for an ESP32.
Doing it this way allowed [joppedc] to not only print in manageable pieces, it also allowed him to use different materials. Getting the front panel to diffuse light correctly took some experimenting to find the right thickness. Eventually, [joppedc] landed on 0.4 mm (two layers) of matte white PLA.
There isn’t much in the way of brains behind this beauty, just an ESP32, a strip of WS2812B addressable LEDs, and a USB-C port for power. But it’s the software stack that ties everything together. The ESP32 has WLED, Home Assistant runs the show, and of course, there is the F1 sensor integration to get live race data.
Some like it flat, and there’s nothing wrong with that. What you are looking at is the first prototype of Atlas by [AsicResistor], which is still a work in progress. [AsicResistor] found the Totem to be a bit cramped, so naturally, it was time to design a keyboard from the ground up.
Image by [AsicResistor] via redditThe case is wood, if that’s not immediately obvious. This fact is easily detectable in the lovely render, but I didn’t want to show you that here.
This travel-friendly keyboard has 34 keys and dual trackpoints, one on each half. If the nubbin isn’t your thing, there’s an optional, oversized trackball, which I would totally opt for. But I would need an 8-ball instead, simply because that’s my number.
A build video is coming at some point, so watch the GitHub, I suppose, or haunt r/ergomechkeyboards.
Flat as it may be, I would totally at least give this keyboard a fair chance. There’s just something about those keycaps, for starters. (Isn’t it always the keycaps with me?) For another, I dig the pinky stagger. I’m not sure that two on each side is nearly enough thumb keys for me, however.
The Foot Roller Scroller Is Not a Crock
Sitting at a keyboard all day isn’t great for anyone, but adding in some leg and/or foot movement throughout the day is a good step in the right direction. Don’t want to just ride a bike all day under your desk? Add something useful like foot pedals.
Brain-wise, it has a wireless macro keyboard and an encoder from Ali, but [a__b] plans to upgrade it to a nice!nano in order to integrate it with a Glove80.
Although shown with a NautiCroc, [a__b] says the wheel works well with socks on, or bare feet. (Take it from me, the footfeel of pedals is much more accurate with no shoes on.) Interestingly, much of the inspiration was taken from sewing machines.
As of this writing, [a__b] has mapped all keys using BetterTouchTool for app-specific action, and is out there happily scrolling through pages, controlling the volume, and navigating YouTube videos. Links to CAD and STLs are coming soon.
The Centerfold: LEGO My Ergo
Image by [Flat-Razzmatazz-672] via redditThis here is a Silakka 54 split keyboard with a custom LEGO case available on Thingiverse. [Flat-Razzmatazz-672] says that it isn’t perfect (could have fooled me!), but it did take a hell of a lot of work to get everything to fit right.
As you might imagine and [Flat-Razzmatazz-672] can attest, 3D printing LEGO is weird. These studs are evidently >= 5% bigger than standard studs, because if you print it as is, the LEGO won’t fit right.

Historical Clackers: the North’s was a Striking Down-striker
Although lovely to gaze upon, the North’s typewriter was a doomed attempt at creating a visible typewriter. That is, one where a person could actually see what they were typing as they typed it.
North’s achieved this feat through the use of vertical typebars arranged in a semi-circle that would strike down onto the platen from behind, making it a rear down-striker.
In order for this arrangement to work, the paper had to be loaded, coiled into one basket, and it was fed into another, hidden basket while typing. This actually allowed the typist to view two lines at a time, although the unfortunate ribbon placement obstructed the immediate character.
The story of North’s typewriter is a fairly interesting one. For starters, it was named after Colonel John Thomas North, who wasn’t really a colonel at all. In fact, North had very little to do with the typewriter beyond bankrolling it and providing a name.
North started the company by purchasing the failed English Typewriter Company, which brought along with it a couple of inventors, who would bring the North’s to fruition. The machine was made from 1892 to 1905. In 1896, North died suddenly while eating raw oysters, though the cause of death was likely heart failure. As he was a wealthy, unpopular capitalist, conspiracy theories abounded surrounding his departure.
Finally, MoErgo Released a New Travel Keyboard, the Go60
It’s true, the MoErgo Glove80 is great for travel. And admittedly, it’s kind of big, both in and out of its (very nice) custom zipper case. But you asked, and MoErgo listened. And soon enough, there will be a new option for even sleeker travel, the Go60. Check out the full spec sheet.
You may have noticed that it’s much flatter than the Glove80, which mimics the key wells of a Kinesis Advantage quite nicely.
Don’t worry, there are removable palm rests that are a lot like the Glove80 rests. And it doesn’t have to be flat –there is 6-step magnetic tenting (6.2° – 17°), which snaps on or off in seconds. The palm rests have 7-step tenting (6°-21.5°), and they come right off, too.
Let’s talk about those trackpads. They are Cirque 40 mm Glidepoints. They aren’t multi-touch, but they are fully integrated into ZMK and thus are fully programmable, so do what you will.
Are you as concerned about battery life as I am? It’s okay — the Go60 goes fully wired with a TRRS cable between the halves, and a USB connection from the left half to the host. Although ZMK did not support this feature, MoErgo sponsored the founder, [Pete], to develop it, and now it’s just a feature of ZMK. You’re welcome.
Interested? The Go60 will be on Kickstarter first, and then it’ll be available on the MoErgo site. Pricing hasn’t quite been worked out yet, so stay tuned on that front.
When I was a kid, I was interested in a number of professions that are now either outdated, or have changed completely. One of those dreams involved checking out books and things to patrons, and it was focused primarily on pulling out the little card and adding a date-due stamp.
Of course, if you’ve been to a library in the last 20 years, you know that most of them don’t work that way anymore. Either the librarian scans special barcodes, or you check materials out yourself simply by placing them just so, one at a time. Either way, you end up with a printed receipt with all the materials listed, or an email. I ask you, what’s the fun in that? At least with the old way, you’d usually get a bookmark for each book by way of the due date card.
As I got older and spent the better part of two decades in a job that I didn’t exactly vibe with, I seriously considered becoming a programmer. I took Java, Android, and UNIX classes at the local junior college, met my now-husband, and eventually decided I didn’t have the guts to actually solve problems with computers. And, unlike my husband, I have very little imagination when it comes to making them do things.
Fast forward to last weekend, the one before Thanksgiving here in the US. I had tossed around the idea of making a personal library system just for funsies a day or so before, and I brought it up again. My husband was like, do you want to make it tonight using ChatGPT? And I was like, sure — not knowing what I was getting into except for the driver’s seat, excited for the destination.
Vibing On a Saturday Night
I want to make a book storage system. Can you please write a Python script that uses SQL Alchemy to make a book model that stores these fields: title, author, year of publication, genre, and barcode number?
So basically, I envisioned scanning a book’s barcode, pulling it up in the system, and then clicking a button to check it out or check it back in. I knew going in that some of my books don’t have barcodes at all, and some are obliterated or covered up with college bookstore stickers and what have you. More on that later.
First, I was told to pip install sqlalchemy, which I did not have. I was given a python script called books_db.py to get started. Then I asked for code that looks up all the books and prints them, which I was told to add to the script.
Then things were getting serious. I asked it to write a Flask server and a basic HTML front end for managing the books in the system. I was given the Flask server as app.py, and then some templates: base.html to be used by all pages, and index.html to view all the books, and add_book.html to, you know, add a new book. At that point, I got to see what it had created for the first time, and I thought it was lovely for a black and white table. But it needed color.
Yeah, so I’ve been busy adding books and not CSS color keywords to genres lately.
Check It Out
This is a great book, and you should read it whether you think you have a problem or not.
I asked the chat-thing for features and implemented them piecemeal, as you do if you’re not a masochist. First up was a cute little trash-can delete-button for every entry. Then it was time to set up the CheckoutEvent. Each of these events records which book it belongs to, whether it’s a check-out or check-in event, and the timestamp of said event. Of course, then it was time to get the checkout history wired to the front-end and accessible by clicking a book’s title.
All I really had to do was add a history route to app.py, update index.html to make the titles clickable, and create the book_history.html it spat out. Then I had it add the buttons for checking in and out on the new checkout history page, which involved adding routes to app.py as well as a helper to compute the current status.
Then it had me modify the history route and update book_history.html with the actual buttons. And they’re super cute, too — there’s a little red book on the checkout button, and a green book on the check-in.
Barcode Blues
On the index.html page, can you add a barcode number-based search box? And when the user searches, redirect them to the book page for that barcode?
Now it was time to get the barcode scanning situation up and running. I was sure at some point that ChatGPT would time me out for the night since I use the free model, but it just kept helping me do whatever I wanted, and even suggesting new features.
I wanted the barcode handling to be twofold: one, it should definitely pull the checkout page if the book exists in the system, and it should also definitely go to the book-entering page if not.
Yes — that’s a great workflow feature. We’ll add a barcode search box to your index page, and when someone submits a barcode, the app will:
Look up the book by barcode
Redirect straight to that book’s checkout history page
Show a nice error if the barcode doesn’t exist
I did what it told me, adding a barcode search route in app.py and updating the index() route to use it. I then added its barcode search form to index.html. It was at this point that I had to figure out a way to generate barcodes so I could make little stickers for the books that lack them entirely, or have otherwise obliterated ones.
I have a pretty basic 1D barcode scanning gun, and it won’t scan everything. As I soon found out, it prefers fake EAN barcodes to UPCs altogether. I finally found an online barcode generator and got to work, starting with a list of randomly-generated numbers I made with Excel. I decided I wanted all the fake barcodes to start with 988, which is close enough to the ISBN 978 lead-in, and happens to use my favorite number twice.
We took a brief detour as I asked the chat-thing to make the table to have ascending/descending sorting by clicking the headers. The approach it chose was to keep things server-side, and use little arrows to indicate direction. I added sorting logic to app.py and updated index.html to produce the clickable headers, and also decided that the entries should be color-coded based on genre, and implemented that part without help from GPT. Then I got tired and went to bed.
The Long, Dark Night of the Solo Programmer
I’m of a certain age and now sleep in two parts pretty much every night. In fact, I’m writing this part now at 1:22 AM, blasting Rush (2112) and generally having a good time. But I can tell you that I was not having a good time when I got out of bed to continue working on this library system a couple of hours later.
There I was, entering books (BEEP!), when I decided I’d had enough of that and needed to try adding more features. I cracked my knuckles and asked the chat-thing if it could make it so the search works across all fields — title, author, year, genre, or barcode. It said, cool, we can do that with a simple SQLAlchemy or_ query. I was like, whatever, boss; let’s get crazy.
Can you make it so the search works across all fields?
It had me import or_ and update the search route in app.py to replace the existing barcode search route with a generalized search using POST. Then I was to update index.html to rename the input to a general query. Cool.
But no. I messed it up some how and got an error about a missing {% endblock %}. In my GPT history it says, I’m confused about step 2. Where do I add it? And maybe I was just tired. I swear I just threw the code up there at the top like it told me to. But it said:
Ah! I see exactly why it’s confusing — your current index.html starts with the <h1> and then goes straight into the table. The search form should go right under the <h1> and before the table.
Then I was really confused. Didn’t I already have a search box that only handled barcodes? I sure did, over in base.html. So the new search code ended up there. Maybe that’s wrong. I don’t remember the details, but I searched the broader internet about my two-layer error and got the thing back to a working state many agonizing minutes later. Boy, was I proud, and relieved that I didn’t have to ask my husband to fix my mistake(s) in the morning. I threw my arms in the air and looked around for the cats to tell them the good news, but of course, I was the only one awake.
Moar Features!
I wasn’t satisfied. I wanted more. I asked it to add a current count of books in the database and display it toward the top. After that, it offered to add a count of currently-checked-out vs. available books, to which I said yes please. Then I wanted an author page that accepts an author’s name and shows all books by that author. I asked for a new page that shows all the books that are checked out. Most recently, I made it so the search box and the column headers persist on scroll.
I’m still trying to think of features, but for now I’m busy entering books, typing up check-out cards on my IBM Wheelwriter 5, and applying library pockets to the inside back covers of all my books. If you want to make your own personal library system, I put everything on GitHub.
On the Shoulders of Giants (and Robots)
I couldn’t have done any of this without my husband’s prompts and guidance, his ability to call shenanigans on GPT’s code whenever warranted, and ChatGPT itself. Although I have programmed in the past, it’s been a good long time since I even printed “Hello, World” in any language, though I did find myself recalling a good deal about this and that syntax.
If you want to make a similar type of niche system for your eyes only, I’d say this could be one way to do it. Wait, that’s pretty non-committal. I’d say just go for it. You have yourself and the broader Internet to check mistakes along the way, and you just might like some of the choices it makes on your behalf.
This week, Hackaday’s Elliot Williams and Kristina Panos met up over coffee to bring you the latest news, mystery sound, and of course, a big bunch of hacks from the previous seven days or so.
On What’s That Sound, Kristina got sort of close, but of course failed spectacularly. Will you fare better and perhaps win a Hackaday Podcast t-shirt? Mayhap you will.
After that, it’s on to the hacks and such, beginning with an interesting tack to take with a flat-Earther that involves two gyroscopes. And we take a look at the design requirements when it comes to building synths for three-year-olds.
Then we discuss several awesome hacks such as a vehicle retrofit to add physical heated seat controls, an assistive radio that speaks the frequencies, and an acoustic radiometer build. Finally, we look at the joys of hacking an old Kindle, and get a handle on disappearing door handles.

Some people are not merely satisfied with functionality, or even just good looks. These persnickety snoots (I am one of them) seek something elegant, a true marriage of form and function.
Image by [YANG SHU] via Hackaday.IOShould such a person be in the market for a macro pad (or ‘macropad’ if you prefer), that snoot should look no further than [YANG SHU]’s 8-key programmable stream deck-like device.
The main goal here was the perfect fusion of display and feel. I’m not sure that an FDM-printed, DIY macro pad can look any better than this one does. But looks are only half the story, of course. There’s also feel, and of course, functionality.
Yes those are (hot-swappable) mechanical key switches, and they are powered by an ESP32-S2. Drawn on the 3.5″ LCD are icons and text for each switch, which of course can be easily changed in the config app.
There’s a three-direction tact switch that’s used to switch between layout profiles, and I’m sure that even this is satisfying on the feel front. Does it get better than this? Besides maybe printing it in black. I ask Hackaday.
KeebDeck Keyboard Gets Two Thumbs Up
Did you make it to Supercon this year? If so, you hold a badge with a special keyboard — a custom job by Hackaday superfriend [Arturo182], aka Solder Party. Were you wondering about its backstory?
This 69-key alphanumeric silicone number has all the keys a hacker needs, plus a rainbow of extras that can be used for macros. According to [Arturo182], the keyboard has a tactile feel thanks to a snap dome sheet underneath the keys, and this makes it more comfortable for long thumb-typing sessions.
Be sure to check out the teasers at the bottom of the KeebDeck page, because there is some really exciting stuff. If you want to build one, GitHub is your friend, pal.
Here’s what I know: That’s a Nulea m512 mouse, the keyboard is a KBD Craft Sachiel LEGO number, and that there is a Cidoo macro pad. Best of all, [Tardigradium] hand-painted the speakers. Neat-o!

Historical Clackers: the Gerda Typewriter Was One of Accessibility
Some of us (okay, I) would have thought that most accessibility inventions are fairly recent, say, from the 1960s onward. But consider the Gerda typewriter, which was created in 1919 to enable blind and one-armed victims of WWI to become employable typists.
According to the Antikey Chop, it’s quite possible that the German government helped grease the wheels of this project so that these soldiers would have a usable typewriter with which to get on with life.
Three versions of this index typewriter were produced: a two-handed Gerda, one with a Braille index, and one with an English index. All entered the market the same year, and were produced for a total of three years.
The Gerda’s typewheel was quite like Blickensderfer, and some even had the DHIATENSOR layout. More expensive than last week’s Clacker (75 Marks), the Gerdas for blind and sighted people with two hands cost 195 Marks, and the one-handed edition was 205 Marks. Some of the two-handed models had rectangular, wooden key-tops, and others had round, glass-topped keys.
Finally, Module-Based Keyboard Is a Sensory Nightmare
I’ve been an early adopter of keyboards in the past. This is usually to bring them to your attention, either before they’re released, or just as they’ve come out. And never have I ever had this poor of an experience.
Games Radar recently reviewed a surprisingly not-failed Kickstarter keyboard that actually shipped, the Naya Create. It may not look like it, but the Create is supposed to be a gaming keyboard. What it does look like is mouse-focused, or at least mouse-forward. And that’s the point of it. Evidently.
Those big modules are interchangeable, and there are four of them so far: the Touch (a trackpad), Track (a trackball that falls out reliably), the Tune (a dial), and the Float, which is designed for space mousing around. They sound cool enough, and might actually be the best part of this whole setup.
To fully illustrate my poit I hvemt’t corrected any of the typos experieved typim this semtemve with the Naya Create while tryig to maintain my usual speed.
But according to Games Radar, the Naya Create is so not worth the $850 (!) asking price. It has ‘mushy, low-profile switches’ and clammy caps, and although the reviewer complains about the non-staggered keys, y’all know that those are my preference at this point.
And apparently, by default, Backspace is mapped to the left side. What? Of course, you can remap any key, whenever the software decides to work. Whenever the reviewer tried to save changes, the software would say that the keyboard is disconnected. Wonderful.
Despite these shortcomings, Games Radar says the keyboard is rock-solid aluminium with good hinges. So there’s that. Just, you know, swap out the switches and keycaps, and wait for software updates, I guess.
We absolutely adore inspired labor-of-love tales such as this one. [Alastair] wanted to build a synth for his daughter’s third birthday in spite of having no prior hardware knowledge. It became the perfect excuse to learn about CAD, microcontrollers, PCB design, and of course, 3D printing.
So, why a synth for a toddler? Aside from plain old ‘why not?’, the story goes that she received a Montessori busy-type board which she seemed to enjoy, and it reminded [Alastair] of the control surface of a synth. He wondered how hard it could be to build something similar that made sound and didn’t require constant button presses.
[Alastair] began his journey by dusting off a 15-year-old Arduino Inventors Kit. The initial goal was to get potentiometer readings and map them to 12 discrete values, and then emit MIDI messages. This was easy enough, and it was time to move to a synth module and an Elegoo Nano.
The full adventure is definitely worth the read. Be sure to check out the pink version in action after the break. You really don’t wanna miss the lil’ panda bear. Trust us.
Have trouble sleeping, or getting to sleep in the first place? You’ve no doubt heard of white noise machines, but know it would be much cooler to make your own. Enter Noise Maker, a DIY sound sculpture by [optimus103733], who wanted to learn something in the process of creating.
The best thing about this sound sculpture aside from the looks is that you can not only play five different sounds (e.g. birds, traffic, water, frog, white noise), you can mix them together into a rich but relaxing cacophony.
As you can probably see from the picture, Noise Maker is based on the ESP32 and uses an SD card module, an amplifier, and five six pots. Be sure to check out the pictures, because there are three layers of copper connections and a lot of careful bending to make it all come together. In the video after the break, you can hear it in action.
It seems [optimus103733] isn’t completely satisfied and wants to make a few improvements in the future, such as a voltage regulator, a power switch, and a timer to automatically stop playback once (we assume) sleep has come. Evidently the ESP32 struggles a little with mixing six audio sources, but hey, lesson learned.
