Why Get Dressed When There Are Software Pants?

May 12, 2022 by Kristina Panos 42 Comments

With so many of us working from home over the last two years, it’s really become apparent that people generally dislike sitting all day with pants on. Until such a utopian time when all clothing is considered unisex, and just as many men as women are kicking it in loose, flowing skirts and dresses, you may want to remember to actually wear something on your lower half, uncomfortable though pants may be. But there is another way — you could build [Everything Is Hacked]’s pants filter and continue to be a chaos agent. Check out the video after the break.

That’s right, whether you forego or just forget to dress yourself below the equator, the pants filter has you covered. It works like you might expect — machine learning tracks body landmarks and posture to figure out where your NSFW region is and keep it under wraps.

By default, it blurs everything below the belt, or you can draw on pants if you’re inclined to be in revealing tighty-whities and prefer more coverage. You can adjust the width of the pants to cover the covid-19 you may have put on since 2020, and even change the pants to match your shirt.

We love that [Everything Is Hacked] had the um, gumption to test the pants filter in public at what appears to be a local taco joint. After the first few rounds of weird looks, he switched to a pants moustache to save face.

Want to add even more fun to those boring video calls? Try connecting up some vintage hardware, or install a pull chain to end those sessions with a gesture that won’t get you fired.

Hackaday Prize 2022: Vintagephone Links The Past To The Present (and Future)

May 11, 2022 by Kristina Panos 21 Comments

Brrrrrrrring! Movies and TV are one thing, but the siren song of a rotary phone ringing in the same room as you is one of those sounds you carry forever. Not old enough to remember them? Ah, so what? There’s no reason to lose these beauties to the annals of time. In fact, we think more old phones should be repurposed so that present and future generations can experience the finger-hookin’ good time of the rotary dial and the high-voltage peal of those brass bells.

That’s exactly what [Giulio Pons] has done with Vintagephone — turned a rotary phone into a digital assistant with an analog interface. He’s reused all the good bits like the rotary dial, the bells, the handset, and the hang-up switch and connected them up to a Wemos ESP8266 development board with a mini motor driver shield and a voltage booster to ring the bells.

When it’s all said and done, [Giulio] will be able to set an alarm by dialing in the time, ring a number to get the current time and date, and ring another number to get the weather forecast. Reminds us of our childhood pastime of calling Time and Temperature to get outside verification that time had, in fact, passed inside the house on those boring rainy days.

Follow along with [Giulio] as the Vintagephone comes to life in the logs, which already have some great instructions for doing a similar number to an old phone you may have lying around. You can find the code on GitHub.

Modifying Old Fonts In The Name Of Baseball

May 11, 2022 by Kristina Panos 4 Comments

Baseball is in full swing again, and having recently accepted a position with Major League Baseball, [Ty Porter] is warming up with a big contribution to the MLB LED Scoreboard project — modifying 20-some old fonts to support baseball’s ‘ꓘ’ character that indicates a special strikeout with a called third strike (meaning the batter didn’t take a swing).

The problem is that Major League Baseball-the-entity recently deprecated the original data source for the scoreboard project. This called for a huge refactor of the codebase, including previously-patched fonts which were now showing either the font’s default no-character character, or nothing at all.

Fortunately, BDF font files are fairly human-readable and make reference to bitmap, which is an actual bitmap in hex. [Ty] settled on Unicode A4D8 (ꓘ), a character from the Tibeto-Burman language Lisu that certainly looks good enough to this baseball fan. Then it became a matter of mirroring the bitmap for ‘K’. [Ty] tried a few things like reversing the nibbles and looking up each one in a table, but that also mirrors the padding, which is bad news.

Then he tried not reversing the nibbles and just looked them up in a table, but this approach dropped and added bits unintentionally. Finally, he tried reversing the order, looking up the reversed nibble, and shifting each byte until there was no padding. This worked for most of the 20 fonts [Ty] patched. The others fell in line with some manual work.

Not much of a baseball fan? You’re almost guaranteed to like this one, especially if you hate mayo.

Thinnest Keyboard Uses Cherry DIY Doubleshot Method

May 10, 2022 by Kristina Panos 24 Comments

As with any other community, it takes all kinds to make the keyboard world go ’round. Some like them thicc — more backing for the clacking and all — but some like them sleek and prefer the slimmest possible keyboard. For now and the foreseeable future, the go-to method for making whisper-thin keebs is to use Kailh Choc switches, because that’s about all that’s out there.

But chocs aren’t for everyone, and there are plenty of die-hard Cherry fans out there that want it both ways. Being one among them, [Khmel] set about designing the lowest-profile possible keyboard (and caps) that uses standard Cherry-sized keyswitches. Shut up and take your money? Well, okay, but the case and keycap files are all available on Thingiverse, so.

The whole video is great, and at less than 2½ minutes long, it’s definitely worth your time. There are a few little gems of wisdom sprinkled throughout, like printing keycaps standing up on their backsides (like where they would have a little flash dot if they were factory-molded). This gives them a nice texture thanks to the layer lines. But the real reason we’re here today is this DIY method for making doubleshot keycaps with little fuss that [Khmel] just tosses out there toward the end.

Trust us, there’s a piece of glass there.

Traditionally, doubleshot keycaps are made with two layers of plastic — one for the legend, and one for the rest. This produces a quite durable keycap and (used to be the norm), but the expensive process gave way to laser-etched and pad-printed keycap legends in the ’90s. [Khmel] was able to fake the look by printing legends at 0.25 layer height and then fusing each one to its respective keycap by laying a thin piece of glass (think microscope slide) on top and applying a soldering iron for a few seconds. Classy!

Tweezing tiny legends not really your kind of tedium? Here’s a method for DIY waterslide decals instead.

Will We Ever Shake The Polaroid Picture?

May 9, 2022 by Kristina Panos 47 Comments

Today, most of us carry supercomputers in our pockets that happen to also take instantly-viewable pictures.This is something that even the dumbest phones do, meaning that we can reasonably draw the conclusion that photographic capability has become a basic feature of everyday carry, a necessity of 21st century life.

Despite the unwashed masses of just-plain-bad photographs clouding the digital landscape, photography itself remains as important as ever so we can retain and disseminate information as history unfolds. In a sense, the more instant, the better — unless it comes at the cost of image quality. The invention of photography is on par with the printing press or with language itself in that all three allow us to communicate within our own time as well as preserve The Way Things Were in frozen silence. And no invention made vivid preservation more convenient than the instant camera.

Mods Make A Stock Keyboard Your Own

May 7, 2022 by Kristina Panos 2 Comments

Trust me, you don’t have to build your own keyboard from the deskpad up to be happy or feel like one of the cool kids. Sure, it doesn’t hurt, but not everyone is able to or even wants to start from next to nothing. Take [Roger] for example. [Roger] started with a stock mechanical keeb — the Ultimate Hacking Keyboard (UHK) — which can be outfitted with magnetic add-on modules such as a thumb key cluster, trackball, trackpoint, and touch pad, and made it his own.

While the stock board that you choose may not be so option-laden, there are plenty of other things one can do to customize things, and [Roger] did basically all of them. The Kailh browns that the UHK came with were too loud, so [Roger] swapped them out for Zilent V2 Silent tactiles and dampened the case with plenty of neoprene foam.

[Roger] frequently switches between two keyboard layouts, which got confusing at times. But instead of boring blank keycaps, he scrounged around until he found a cool set. (We do like the way they look with the wood wrist rests.) Speaking of those wrist rests, the right one is carved out and hiding a 10,000 mAh power bank, because [Roger] also made the UHK wireless using one of those often-out-of-stock BT-500 Bluetooth adapters. This allows him to switch between two PCs with a keyboard shortcut.

Think you want to go split, but not sure about key wells and column stagger and all that jazz? Something like the UHK is a good place to start, because it takes the familiar brick wall layout and breaks it into two pieces. No idea what you want? Check out the split keyboard finder.

Pico Chording Keyboard Is Simultaneously Vintage And New

May 6, 2022 by Kristina Panos 9 Comments

On paper, chording — that’s pressing multiple keys to create either a single character or a whole word — looks like one of the best possible input methods. Maybe not the best for speed, at least for a while, but definitely good for conserving the total number of keys. Of course, fewer keys also makes for an easier time when it comes to building keyboards (as long as you don’t have to code the chording software). In fact, we would venture to guess that the hardest part of building your own version of [CrazyRobMiles]’s Pico Chord Keyboard would be teaching your fingers how to work together to chord instead of typing one at a time.

[CrazyRobMiles] took inspiration from the Cykey chording design used for the Microwriter and later, the Microwriter Agenda that also featured a qwerty blister keyboard. Both featured small screens above the six keys — one for each finger, and two for the thumb. While the original Microwriter ran on an 8-bit microprocessor, Pico Chord Keyboard uses — you guessed it — the Raspberry Pi Pico.

We love that [CrazyRobMiles] went with four 14-segment displays, which gives it a nice old school feel, but used transparent keycaps over Kailh switches. This is actually important, because not only do the LEDs show what mode you’re in (alpha vs. numeric vs. symbols), they also teach you how to chord each letter in the special training game mode. Be sure to check it out in the video after the break.

Isn’t it cool that we live in a world of relatively big keyboards with few keys and tiny keyboards with all the keys?
