Keebin’ With Kristina: The One With The Pumpkin Keyboard

November 8, 2022 by Kristina Panos 9 Comments

Oh, the places plastic has taken us. One of the arguably better inventions might be the fake carve-able pumpkin, which is more or less guaranteed not to shrivel up and rot on your porch, though it might get smashed by wily teenagers along with its organic brethren next door.

Though they will be around much longer, the fake kind lend themselves to all kinds of creations, including this one from [BunkEbear] which was “a nightmare” to build. Yeah, we bet it was along the lines of [Aaron Rasmussen]’s spherical keyboard, except inside out, since that one’s concave.

This tasty keyboard is modeled after the Malling-Hansen writing ball, which is arguably the first commercial typewriter and dates to 1865. [BunkEbear]’s pumpkin version features the 54-key layout, plus two additional for Shift and Escape to suit modern needs. Since the inside of the pumpkin is pretty small, [BunkEbear] wired all the connections close together on the protoboard, and used JST extension cables between the Glorious Panda switches themselves and the Arduino Pro Micro.

Keyboard One Is An Ear Of Corne

November 4, 2022 by Kristina Panos 16 Comments

There are all kinds of avenues into the mechanical keyboarding hobby, and one of the more well-traveled ones runs between coworkers. [crsayen] aka [DrJamesOIncandenza] has one such relationship, and was turned on to the CRKBD a while back by an office mate. For the uninitiated, that’s short for Corne keyboard, which is a column-staggered 3×6 split keyboard with three thumb keys per hand.

While [JOI] liked the Corne well enough, especially with chocs, he got the occasional craving to slap (that’s what we’re calling typing on linears from now on — slapping vs. clacking) on some silent MX switches and so built this Corne-derivative monoblock split called Keyboard One. Aside from the more obvious differences,

We think this looks rather spanking for a first keyboard, sort of like a slightly smaller Alice or something. But you don’t have to go to great lengths to obtain [JOI]’s knowledge, for everything is on GitHub. [JOI] says they sort of regret going 3×6, but are already planning another build with more keys. See, that’s the spirit.

Hackaday Prize 2022: Ultratower Is A Powerful Gardening Vertical

November 4, 2022 by Kristina Panos 29 Comments

The more people we have on this planet, the more food we need. Naturally, this extends to water, another precious resource that generally plays a part in farming and food production. And honestly, we’d probably all eat a little better if it were really easy to grow healthy things like spinach. Well, that excuse doesn’t work anymore, thanks to [J Gleyzes]’ Ultratower. It’s a simple-to-use hydroponic tower that uses recycled mist to water plants, ultimately saving water in the process.

The ‘ultra’ part is a function of the way mist is created. In this case, it’s done with three piezoelectric disks mounted under a tank in the top of the PVC tube. Stick up to twelve plants in the little cubbies, and their roots will grow down the inside, where they’ll receive a fine shower of water at your command. Water that runs off the roots collects in a small tank at the bottom, where a pump starts the process over again.

At first, [J Gleyzes] had trouble with the piezo disks — using 1.7MHz disks created too much heat, warming the water up to nearly 40°C (104°F). Since cooking the spinach prematurely would be bad, they experimented with other values, finally landing on 108KHz. Be sure to check out the video after the break.

Heirloom Knife Will Carve Pumpkins For Years To Come

November 3, 2022 by Kristina Panos 6 Comments

Halloween may be behind us, but that just means that we’ve reached the best time to buy pumpkins. After all, it’s still fall, and there are pies to be made and tables to be decorated. Why should carved-up pumpkins be restricted to spooky season?

The only problem is that it’s 2022, and we’re still expected to use those terrible little serrated knives to carve our pumpkins. Those orange-handled garbage ‘knives’ are hardly suited to cut the lid, much less carve any of the intricate designs that come in the little booklet. So what’s a pumpkin-carving enthusiast to do? If you’re [XYZ Create], you make your own out of walnut, maple, and a gently-used jigsaw blade that’s still way sharp enough to tear through pumpkin flesh.

[XYZ Create] started with a nice chunk of walnut, which he split lengthwise in order to insert the blade, which sits in a cavity within a thin piece of maple. Once [XYZ Create] had the handle ready to go, he inserted the jigsaw blade and epoxied the sandwich together. After sanding down the edges to make a comfortable grip, he finished off the build by rubbing a bit of carving board wax into the handle. Check out the build video after the break.

Cursive Out Loud: Dealing With Dragons

October 28, 2022 by Kristina Panos 21 Comments

When we last left this broadening subject of handwriting, cursive, and moveable type, I was threatening to sing the praises of speech-to-text programs. To me, these seem like the summit of getting thoughts committed to what passes for paper these days.

A common thread in humanity’s tapestry is that we all walk around with so much going on in our heads, and no real chance to get it out stream-of-consciousness style without missing a word — until we start talking to each other. I don’t care what your English teacher told you — talking turns to writing quite easily; all it takes is a willingness to follow enough of the rules, and to record it all in a readable fashion.

But, alas! That suggests that linear thinking is not only possible, but that it’s easy and everyone else is already doing it. While that’s (usually) not true, simply thinking out loud can get you pretty far down the road in a lot of mental vehicles. You just have to record it all somehow. And if your end goal is to have the words typed out, why not skip the the voice recorder and go the speech-to-text route?

Cyberdeck Contest 2022: Gibson Rev 001 Thinks Outside The Pelican Case

October 25, 2022 by Kristina Panos 5 Comments

As we’ve gushed previously in these pages, we saw an incredible turnout for our first-ever cyberdeck contest — so many cool ‘decks rolled in that it made judging them all quite the feat, and we would be remiss if we didn’t feature the favorites that, for whatever reason, didn’t make the cut. One of these is the aptly-named Gibson Rev 001 from [Gadjet].

This cyberdeck may be on the pocket-sized side of things, but don’t let that fool you, because it’s loaded with I/O and sensors galore. A Pimoroni Breakout Garden provides particle/smoke and pulse oximetry, temperature/pressure/altitude, an air quality sensor, and a UVA/UVB light sensor — plenty of feelers for judging conditions on the fly. As you might expect, the brains of the operation is a Raspi 4, which is running Twister OS.

We love the dual-display thing going on with the 7″ touchscreen and the color e-ink display — really gives it a cobbled-together-yet-polished, futuristic feel. May the rest of the post-apocalypse gadgetry have such clean lines and cheerful colors (if that’s what you’re into).

Hackaday Podcast 190: Fun With Resin Printing, Tiny Tanks, Lo-Fi Orchestra, And Deep Thoughts With Al Williams

October 21, 2022 by Kristina Panos 3 Comments

This week, Editor-in-Chief Elliot Williams and Assignments Editor Kristina Panos rendezvoused in yet another secret, throwaway location to rap about the hottest hacks from the previous week. We start off by gushing about the winners of the Cyberdeck Contest, and go wild over the Wildcard round winners from the Hackaday Prize.

It’s the What’s That Sound? results show, and Kristina was ultimately stumped by the sound of the Kansas City Standard, though she should have at least ventured a guess after shooting down both modem and fax machine noises.

Then it’s on to the hacks, which feature an analog tank-driving simulator from the 1970s, much ado about resin printing, and one cool thing you can do with the serial output from your digital calipers, (assuming you’re not a purist). And of course, stay tuned for the Can’t-Miss Article discussion, because we both picked one of resident philosopher Al Williams’ pieces.
