Greatest Keycaps And Where To Find Them

April 28, 2020 by Kristina Panos 25 Comments

Look at your keyboard. Do the keycaps excite you? That’s what we thought. You pound on that thing day in and day out. Shouldn’t it at least be attractive? Or even happiness-inducing? You don’t necessarily have to replace every single keycap to spark joy. When it comes to artisan keycaps, the point is to have something that stands out.

How about an Escape key that looks like a tall stack of flapjacks or a tiny, intricate cream puff? From a practical standpoint, how about a spiky Escape key that makes you think twice about rage quitting?

If you’re into games or anime, chances are good that there are more than enough artisan keycaps out there to keep you cash-poor for a while. The same goes for scrumptious foodstuffs with Cherry MX-compatible stems.

In this day and age, you can get just about any type of keycap you want, especially those encapsulating pop culture phenomena and fads. Yes there’s a fidget spinner keycap, and it’s adorable.

Hackaday Links: December 29, 2019

December 29, 2019 by Dan Maloney 25 Comments

The retrocomputing crowd will go to great lengths to recreate the computers of yesteryear, and no matter which species of computer is being restored, getting it just right is a badge of honor in the community. The case and keyboard obviously playing a big part in that look, so when a crowdfunding campaign to create new keycaps for the C64 was announced, Commodore fans jumped to fund it. Sadly, more than four years later, the promised keycaps haven’t been delivered. One disappointed backer, Jim Drew, decided he was sick of waiting, so he delved into the world of keycaps injection molding and started his own competing campaign. Jim details his adventures in his ~~Kickstarter~~ Indiegogo campaign, which makes for good reading even if you’re not into Commodore refurbishment. Here’s hoping Jim has better luck than the competition did.

Looking for anonymity in our increasingly surveilled world? You’re not alone, and in fact, we predict facial recognition spoofing products and methods will be a growth industry in the new decade. Aside from the obvious – and often illegal – approach of wearing a mask that blocks most of the features machine learning algorithms use to quantify your face, one now has another option, in the form of a colorful pattern that makes you invisible to the YOLOv2 algorithm. The pattern, which looks like a soft-focus crowd scene rendered in Mardi Gras colors, won’t make the algorithm think you’re someone else, but it will prevent you from being classified as a person. It won’t work with any other AI algorithm, but it’s still an interesting phenomenon.

We saw a great hack come this week about using an RTL-SDR to track down a water leak. Clayton’s water bill suddenly skyrocketed, and he wanted to track down the source. Luckily, his water meter uses the encoder receive-transmit (ERT) protocol on the 900 MHz ISM band to report his usage, so he threw an SDR dongle and rtlamr at the problem. After logging his data, massaging it a bit with some Python code, and graphing water consumption over time, he found that water was being used even when nobody was home. That helped him find the culprit – leaky flap valves in the toilets resulting in a slow drip that ran up the bill. There were probably other ways to attack the problem, but we like this approach just fine.

Are your flex PCBs making you cry? Friend of Hackaday Drew Fustini sent us a tip on teardrop pads to reduce the mechanical stress on traces when the board flexes. The trouble is that KiCad can’t natively create teardrop pads. Thankfully an action plugin makes teardrops a snap. Drew goes into a bit of detail on how the plugin works and shows the results of some test PCBs he made with them. It’s a nice trick to keep in mind for your flexible design work.

Tokyo Mechanical Keyboard Meetup Knocks Our Clacks Off

June 5, 2019 by Kerry Scharfglass 7 Comments

Just a few days ago, on the other side of the planet from this author, there was a mechanical keyboard meetup in Tokyo. Fortunately through the magic of the Internet we can all enjoy the impressive collection of devices people brought, and boy were there some interesting specimens. There were certainly the inevitable collections of strange artisan keycaps, unusual handmade switches, and keycap sets only available in one group buy five years ago in Nicaragua. But among the bright colors were some truly unique custom designs the likes of which we haven’t see before. A single source is hard to credit, you could check the hashtag #tokyomk6 on Twitter, or [obra]’s thread of photos, or this great blog post (video walkthroughs and photos included) from [romly].

Speaking of [romly], one of their designs stands out as particularly unusual. There are a few things to note here. One is the very conspicuous surface profile of the (clearly totally custom) keycaps themselves. Instead of flat or cylindrical or spherical, these are round. Round like the outside of a log. If we didn’t know better it might look like the entire thing was sculpted or extruded as a single unit. And just below the deck are the perpendicular thumb clusters. Frankly we aren’t sure how to refer to this design feature. The switches are mounted at right angles facing inward so the user places a thumb inside it in a style reminiscent of the DataHand. It’s quite interesting, and we’d be love to know more about what specific functionality it provides.

Another interesting entrant is this keyboard with unusually staggered switches and hexagonal caps (check out the individual markings!). Very broadly there are two typical keyboard layout styles; the diagonal columns of QWERTY (derived from a typewriter in the 1800’s) or the non slanted columns of an “ortholinear” or matrix style layout. By those metrics this is something like an ortholinear keyboard in that its switches overlap their neighbors by half, but the edge to edge close packed caps imply that it might be something else. We’d be very interested to know how typing on this beast would be!

There were so many more awesome designs present at the meetup that this would never end if we tried to document them all. Take a look through the posts and call out anything else too excellent to go unnoticed!

Thanks [obra] for Tweeting about this so we could discover it.

Handmade Keyboards For Hands

February 3, 2017 by Brian Benchoff 11 Comments

There were some truly bizarre computer keyboards in the 1980s and 90s. The Maltron keyboard was a mass of injection-molded plastic with two deep dishes for all the keys. The Kinesis Advantage keyboard was likewise weird, placing the keys on the inside of a hemisphere. This was a magical time for experimentations on human-computer physical interaction, the likes of which we haven’t seen since.

Now, though, we have 3D printers, easy to use microcontrollers, and Digikey. We can make our own keyboards, and make them in any shape we want. That’s what [Andrey]’s doing. The 32XE is an ergonomic keyboard and trackball combo made for both hands.

The keyboard has curved palm rests, a trackball under the right thumb, and is powered by the ever popular DIY mechanical keyboard microcontroller, the Teensy 2.0. This keyboard is equipped with a trackball, and that means [Andrey] needed a bit of extra electronics to handle that. The mouse/trackball sensor is built around the ADNS-9800 laser motion sensor conveniently available on Tindie. This laser mouse breakout board is built into the bottom of the keyboard, with enough space above it to hold a trackball… ball.

Since this is a very strange and completely custom keyboard, normal mechanical keyboard keycaps are out of the question. Instead, [Andrey] 3D printed his own keycaps on an FDM printer. Printing keyboard keycaps on a filament-based printer is extremely difficult — the tolerances for the connector between the switch and cap are tiny, and nearly at the limit of the resolution of a desktop filament printer. [Andrey] is taking it even further with inlaid keyboard legends. He’s created a keycap set with two color legends on two sides of the keycaps. If you’ve ever wanted to print keycaps on a 3D printer, this is a project to study.

In case you haven’t heard, we’re giving away a trip to space. We have $50,000 to promote giving away a trip to space too, and this week we’re giving away some OSH Park gift cards. If you have a project that’s held together with hot glue on a 40-year-old piece of perf board, add a project log describing how you need some free PCBs.

A few months ago, some guy in Texas found the original molds for the Commodore 64C, the Plus/4 and the 128. That discovery turned into one of the best examples of what Kickstarter can do. Now, new keycaps are being manufactured with an Indiegogo campaign. If you’re waiting on your C64c case to be pressed out of a mold, this is not the time to think about the sunk cost fallacy. They’re not Cherry MX compatible, but they will work with just about every version of the C64. Not bad for under €20.

The UK has a fabulously rich history of ancient melee weapons, ranging from the flail to the mace and a bunch of odd bladed weapons used by the Scots. This tradition was passed down to the UK mains plug, the single most painful plug to step on. Apple just released a USB charger with a folding UK mains plug and [oliver] did a teardown on it.

For St. George’s Day in Catalonia, there’s a tradition of giving roses to women, and books to men. [Nixieguy] has all the books he could want, and would prefer to receive a rose. Bucking tradition, he made himself a rose from a punch card. It’s the closest he’s going to get to ‘@}-\—’. A few years ago, he carved a rose out of a 10mm LED.

Finally, a decent tutorial on how to grow your own SMD components.

Need to take apart a cellphone? Use acetone! Need the phone to work after you take it apart? Ummmm….

The Dayton Hamvention is just three weeks away! Yes, the same weekend as the Bay Area Maker’s Faire, which means most of the Hackaday crew will be elsewhere, but I hear [Chris Gammell] will be there putting Parts.io stickers on everything. By the way, I’m looking for a Tek PM203 Personality Module for a 68000 64-pin PDIP.

Introducing the Hayes Smartmodem 1200. The era of the single station microcomputer…. is over. The Hayes Smartmodem offers advanced features like auto answer and auto dial. Now if we could only find an ‘RS-232 Computer.’

Have a 3D printer and an old router? How about controlling your printer with Octoprint? For some cases, it might be better than using a Raspberry Pi and OctoPi, but you won’t get a camera for streaming pics of your builds to the web.

Last year, [CNLohr] built a microscope slide Minecraft thing and in the process created the smallest Minecraft server ever. The record has now been bested with the Intel Edison. There’s a bit of work to install Java, but the performance is pretty good for one player. Bonus: Minecraft is a single threaded app, so you have another core for garbage collection.

Remember the Scribble pen, that showed just how gullible people are and how crappy tech journalism is? They’re back with a beta program. A mere $15 guarantees you a scribble pen for their beta program. I wouldn’t give these guys $15 of someone else’s money, but lucky for us [ch00f] bit the bullet. He’ll be updating everyone on the status of his fifteen dollars, I’m sure.

Hey, guess what will eventually be in the Hackaday store? Keycaps for your mechanical keyboard. Yes, we actually figured out a way to do this that makes sense and won’t lose money. Pick your favorite, or suggest new ones in the comments:
