Inputs Of Interest: X-Bows Ergo-Mechanical Keyboard

Okay, let’s just get this out of the way up front, shall we? This ergonomic mechanical keyboard was a free sample offered to me by X-Bows. They contacted me after I expressed interest in trying one in the comments of my post about the Kinesis Advantage. I had my doubts about this keyboard as far as my own personal ergonomic needs go, which are admittedly on the extreme side. TL;DR: I won’t be abandoning my curvy girls anytime soon. But I will say that I’m definitely impressed by the X-Bows.

X-Bows was founded by a doctor who saw a lot of RSI issues in programmers and writers and decided to take matters into his own hands. The keyboard was born on Kickstarter in 2017 and now comes in three models. They sent me the mid-range model called The Knight, which retails for $249, but seems to be on permanent sale for $199. The top-of-the-line Knight Plus has a magnetic, detachable 10-key that can attach to either side. Continue reading “Inputs Of Interest: X-Bows Ergo-Mechanical Keyboard”

“You Sank My Dysprosium!”: Periodic Table Battleship

Kids these days, they have it so easy. Back in the old days, we learned our elements the hard way, by listening to “The Elements” by Tom Lehrer over and over until the vinyl wore out on the LP. Now, thanks to [Karyn], kids can learn the elements by playing “Battleship” – no tongue-twisting lyrics required.

For anyone familiar with the classic “Battleship” game, you’ll wonder why no one thought of this before. [Karyn]’s version of the game is decidedly low-tech, but gets the job done. She printed out four copies of the periodic table, added letters to label the rows, and laminated them. A pair of tables goes into a manila file folder, the tops get clipped together, and dry-erase markers are used to mark out blocks of two to five elements to represent the ships of the Elemental Navy on the lower table. Guesses at the location of the enemy ships can be made by row and series labels for the elementally challenged, or better yet by element name. Hits and misses are marked with Xs and Os on the upper table, and play proceeds until that carrier hiding in the Actinide Archipelago is finally destroyed.

This is pure genius in its simplicity and practicality, but of course there’s room for improvement. The action-packed video after the break reveals some structural problems with the file folders, so that’s an obvious version 2.0 upgrade. And you can easily see how this could be used for other tabular material – Multiplication Table Battleship? Sounds good to us. And if your nippers catch the chemistry bug from this, be sure to take a deeper dive into the structure of the periodic table with them.

Now, if you’ll excuse me: “There’s antimony, arsenic, aluminum, selenium, and hydrogen and oxygen and nitrogen and rhenium….”

Maker Faire 2008: RoboGames And Warships

Today’s episode of BoingBoing TV comes straight from Maker Faire. The first segement is about RoboGames arena combat. The second segment covers a favorite exhibit of mine. Western Warship Combat Club brought their 1/144th scale battleships to fight it out in a large pool. The RC boats fire ammunition up to 1/4-inch ball bearings and the even feature bilge pumps to keep them afloat. Scoring is based on where on the hull the strike happens. Here’s a direct link to the mp4.
