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.

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.

Gone in 60 Seconds: the Micro Journal Rev. 7 From Tindie

Don’t know what took me so long to find r/writerDeck, but here we go! [WorkingAmbition7014] was quite excited to announce there that [Background_Ad_1810] aka [Un Kyu Lee]’s Micro Journal rev. 7 was up on Tindie. It’s already sold out, but that’s okay because previous versions are already open-source, and it’s just a matter of time before this new revision makes its way to the ole GitHub.

This distraction-free machine is based on the ESP32-S3 microcontroller. It starts up right away, and you can start typing pretty much immediately on the ePaper screen. There are a pair of knobs that go a long way toward its typewriter looks; the left one wipes the screen and puts the machine to sleep, and the right knob clears the screen in the case of too much ghosting.

Files are saved on the SD card that sits behind the screen, or you can send them to Google Drive. Now, it doesn’t come with that cool clip light, but it doesn’t have a backlight, either, so you’ll probably want to bring your own. You will also have to source your own 18650. Be sure to check out the overview after the break.

The Centerfold: Purple Paradise

I love these setup pictures, but I have to wonder, does anyone really keep their desk this clean and tidy? Of course not, it’s for the shot, you’re saying. But that’s my point. Why does everyone always tidy up so hard first? I want to see battle stations in their true forms sometimes. I feel like we got sorta close last week in the one with all the screens. So do I need to inspire centerfold submissions by showing my own battle station one of these times? I don’t know if y’all really want that.

Do you rock a sweet set of peripherals on a screamin’ desk pad? Send me a picture along with your handle and all the gory details, and you could be featured here!

Historical Clackers: the Ford Typewriter

Isn’t this machine a beauty? And no, inventor Eugene A. Ford bore no relation to Henry Ford the automobile maker. But wouldn’t this look grand while perched briefly on the running board of your Model T for a quick daguerreotype?

Lovely as she was, the 1895 Ford was no fun for the typist. The Space bar-placed Shifts required real pressure to properly operate, and the keys are evidently springy and wobbly. “Springy” sounds intriguing; “wobbly” does not.

Additionally, the advancing lever doesn’t allow going backwards or forwards a line at a time. But the one great thing about the Ford was that it’s a visible writer, whereas most machines of the time were blind writers, meaning you were unable to see what you were typing without stopping and doing something first. It wasn’t the first visible writer, but it might be the easiest to look at.

What it did do first is use aluminium in its construction, although there were two versions, one with an all-aluminium frame and carriage, and the other with a black, enameled cast iron frame and and an aluminium carriage. The cast iron went for $75, and the lighter-weight aluminium machine for $85. Both were lateral thrust machines, which means that the type bars are spread out like a fan and move horizontally to strike the platen.

Eugene Ford had quite the career. After putting his typewriter on the market in 1895, he worked with IBM for the rest of his life, and became chief development engineer of the New York laboratories in 1911. During his tenure, he developed improvements to various punched card accounting machines, sorters, and counters.

Finally, a Keyboard for Cat Lovers

Cats and keyboards go together like peanut butter and jelly. When they’re not straight up walking across it, they’re fluffing it up. Well, why not admit defeat and get this cozy cat-themed keyboard?

This is the Dry Studio Petbrick 65, which comes in calico and black, which is called the odd-eyed design, presumably because the kitty on the Escape key has heterochromia.

Now that’s just the keyboard itself that comes in calico and black; soon you’ll be able to get all kinds of fuzzy bezels, which attach with magnets and are hand-washable, thankfully.

The Petbrick 65 isn’t just some cutesy little thing. This is a serious mechanical keyboard with a sandblasted POM plate, a specially-tuned (what? how?) cotton poron switch pad, PET film for the sake of acoustics, and two layers of sound-dampening foam.

The switches are custom-made ‘crystal pinks’ that were developed in-house and look pretty slick. If you don’t like them, the PCB is hot-swappable. And they didn’t stop there — the keycaps have dye-sublimated legends for longevity.

Would I type on this? I would, at least until it became uncomfortable for my RSI situation. I’m interested to try these crystal pink switches and feel the fluffiness of the frame on the heels of my hands.

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.

While most pet owners are happy to help out their furry friends, everyone has a limit. For [Gauthier], getting up to open or close the window every three minutes so their cat can go out on the balcony was a bridge too far, so they decided to take a crack at automating the window. The end result not only does the job, it’s extremely low-tech and pretty much invisible except when in use.

Of course, [Gauthier] didn’t arrive at this solution immediately. Their first thoughts went to RFID or perhaps a pressure sensor to detect the cats, coupled with something motorized to open and shut the window, like a belt or maybe a linear actuator. But ultimately, the system has to be robust, so that’s when [Gauthier] got the idea to employ gravity by using pulleys and weights.

Due to the configuration of the space and the shape of the window, [Gauthier] was able to to hide cable pretty well — you can’t really see anything when the window is closed. Be sure to check it out in action after the break.

Cats are wonderful creatures to have around, and they provide us with hours of entertainment. So why not do a little something to entertain them in return? That’s exactly what [Becky Stern] did by making a cat TV that shows YouTube videos of birds and other cat-approved content. Not all cats seem to care about TV, but [Becky]’s cat Benchley really gets into it.

As you may have guessed, this is a fairly simple build, consisting largely of a Raspberry Pi, a speaker, and a screen — a 5″ HDMI LCD display to be exact. Seems like a nice size for cats. After getting the cat-puter up and running, [Becky] set about designing a 3D-printed enclosure to turn it into a TV. The first draft looked great in marble-effect filament, but lacked breathing holes for the Pi, so the final version has a nice honeycomb pattern that is too small for curious cat paws to fit through.

What their paws can do is accidentally pause the video via the touch screen, so [Becky] swapped the USB cable for a charge-only to prevent this. Be sure to check out the build video after the break, because there is plenty of cat cuteness to be had. [Benchley] was so into it that he went looking around back for cats and squirrels inside the box.

Would you rather not encourage your cats to lie about the house watching TV all day? Make them play piano for their dinner.

When you have three cats and three humans, you have one problem: feeding them on a schedule without over or under feeding them. Even if there was only one human in the equation, the Cat-o-Matic 3000 would still be a useful tool.

Essentially, it’s a traffic light for cats — where green means you are go for feeding, and red means the cat was just fed. Yellow, of course, means the cat is either half-full or half-empty, depending on your outlook.

The brains of this operation is an ATmega88PA leftover from another project. There’s a no-name voltage regulator that steps up the two AA cells to 5 volts. Timing comes from a 32 kHz crystal that allows the microcontroller to stay in power-saving sleep mode for long periods of time.

Creator [0xCAFEAFFE] says the firmware was cobbled together from other projects. Essentially, it wakes up once per second to increment the uptime counter and then goes back to sleep. Short-pressing a button shows the feeding status, and long-pressing it will reset the timer.

Wanna make a cat status indicator without electronics? Give flexures a try.

Pandemic induced boredom takes people in many different ways. Some of us go for long walks, others learn to speak a new language, while yet more unleash their inner gaming streamer. [Niklas Fauth] has taken a break from his other projects by creating a very special project indeed. A cat detector! No longer shall you ponder whether or not the object or creature before you is a cat, now that existential question can be answered by a gadget.

This is more of a novelty project than one of special new tech, he’s taken what looks to be the shell from a cheap infra-red thermometer and put a Raspberry Pi Zero with camera and a small screen into it. This in turn runs Tensorflow with the COCO-SSD object identification model. The device has a trigger, and when it’s pressed to photograph an image it applies the model to detect whether the subject is a cat or not. The video posted to Twitter is below the break, and we can’t dispute its usefulness in the feline-spotting department.

[Niklas] has featured here more than once in the past. This is not his only pandemic project, either.

[ANTALIFE] is going to tie the knot sometime in 2017. Instead of sending out paper announcements or just updating his Facebook status, he wanted to give their family members something lasting and memorable, like a small trinket with a pair of light-up cats.

This project is pretty simple in theory. A pair of RGB LEDs cycle through the colors of the rainbow with the help of an ATtiny25 and resistors carefully chosen for each LED. But there are several challenges at play here. [ANTALIFE] wanted to design something quite small that would last at least a day on a single CR2032 coin cell. This project was his first foray into SMD/SMT design and construction. We think that this warrants its own congratulations, especially since it looks as though he made at least a dozen of these things.

[ANTALIFE] made things much easier for himself with the purchase of a cheap hot air rework station and used a chip clip to program the ‘tiny. The cats are a design from Thingiverse, which he modified to turn them into bride and groom. Watch a whole line of them glow after the break. We sincerely hope that a larger version of these cats end up on top of the wedding cake.

For anyone with an undying love blinkenlights and impending nuptials, don’t forget the light-up invitations, wedding attire, and centerpieces.

Thanks for the tip, [Brendan].
