Keebin’ With Kristina: The One With The Busy Box Macro Pad

September 21, 2023 by Kristina Panos 7 Comments

Well, I must admit that Google Translate completely failed me here, and thus I have no real idea what the trick is to this beautiful, stunning transparent split keyboard by [illness072]. Allegedly, the older tweets (exes?) hold the key to this magic, but again, Google Translate.

Based on top picture, I assume that the answer lies in something like thin white PCB fingers bent to accommodate the row stagger and hiding cleverly behind the keys.

Anyone who can read what I assume is Japanese, please advise what is going on in the comments below.

Ballistic BMW Blocks Both Bullets And Booms

September 21, 2023 by Kristina Panos 47 Comments

Maybe you like to live dangerously. Like, James Bond dangerously. Well, we won’t judge, but we will pass this along — BMW has created the ultimate driving machine for shootouts and war zones.

Rather than having aftermarket anti-ballistic bits and bobs attached at a later date, this BMW 7 Series is born anti-ballistic and explosion-resistant, built from the ground up with armor steel. They call this the BMW Protection Core.

By building it this way, there are many advantages like more cabin space, lower curb weight, and better handling, which is exactly what you’d want if you were under these types of attacks.

For starters, the car has chunkier A-pillars and door/window frames meant to withstand the damage pictured here. The car has special armoring in the roof and undercarriage to withstand explosions. And the fuel tank is self-sealing, so you have a chance at getting out of there if the thing takes a bullet.

Can’t afford this ballistic-grade beast? You could always roll your own armored vehicle.

Spooky Noise Box Plays War Drums

September 20, 2023 by Kristina Panos 6 Comments

What do you have cooked up to scare trick-or-treaters this Halloween? We humbly suggest adding in some type of noise box, especially one like this offering from [Paisley Computer] that uses reverb and other effects to achieve chilling, thrilling sounds.

As you can see, this instrument is essentially a bunch of doodads affixed to and through a cigar box. And as you’ll hear in the first video after the break, the various rubber bands make great drum sounds. The springs are nice, too, but our personal favorite has to be the head massager thing. Shhhing!

Inside the box you’ll find a guitar jack and some piezos glued to the underside of the top surface, but you’ll also find springs mounted across the inside that add to the resonance of the cigar box.

You can use either an interface and DAW or an effects pedal chain to really make things freaky, and [Paisley Computer] does a showdown between Focusrite interface versus various stomp pedals in the second video. In the third video, we learn how to make one of our own.

Do you like the idea of a spring reverb? How about a really big one that sounds sort of Satanic?

Salad Spinner Busts Some New Moves

September 20, 2023 by Kristina Panos 18 Comments

Can you believe that [Tom Tilley]’s wife was just going to pawn off this perfectly good salad spinner on the thrift store when it’s so ripe for hacking? We couldn’t, either. Fortunately, he caught it just in time, right before dinner.

One of the coolest things a person can do that also tends to aid gameplay is to make a custom controller. [Tom] decided to make one for Bust-A-Move, a simple game where one shoots balls at bubbles in order to pop them. It looks like quite the fun little stress reducer. Anyway, a simple game deserves a simple controller, no? Yes.

As you’ll see in the build/demo video below, [Tom] started with a standard wireless mouse and hot-glued a cardboard origami creation to it. This goes upside-down inside the salad spinner and gets connected to the spinner part so that the entire origami moves in a circle. [Tom] then extended the left mouse button to a switch, which he affixed to the outside.

This controller re-uses a slightly modified mouse that [Tom] used in a previous Bust-A-Move controller. He is using a FreePIE script and vJoy in order to map mouse movements to the joystick inputs expected by the game. Watch [Tom] bust some moves after the break.

You’ve Got Mail: Reading Addresses With OCR

September 20, 2023 by Kristina Panos 14 Comments

Last time I delivered on this column, I told you about the USPS’ attempts to fully automate a post office. Of course, that’s a bit of a misnomer, since it took 1,500 employees to actually operate the place on a daily basis. Although Project Turnkey in Rhode Island and Project Gateway in California were proving grounds for all kinds of mail sorting and processing equipment, the act of actually reading addresses and routing mail to its final destination still required human intervention and hand coding.

Today, the post office processes hundreds of millions of mail pieces each day using various pieces of equipment. One of those important pieces of equipment is the OCR address reader, which manages to make sense of all kinds of chicken scratch.

Time And Tide Are One Thing

September 19, 2023 by Kristina Panos 3 Comments

The rise of 3D printing has given us incredible things, from awesome tchotchkes to intricate chocolates to useful things like spare body parts. But none has been so vital to comedy as say, printing hats for sea urchins. That’s right, sea urchins like to cover up with various things and will happily don, say, a 3D printed hat if presented the opportunity.

So anyway, this is a tide clock that uses a printed sea urchin and various hats to tell the time until/between low and high tide. How? It uses the position of a given hat relative to a couple nOOds LED strands, one for high tide and another for low.

Inside the large bamboo enclosure is an TTGO that fetches cheaply-obtained tide information and displays it on the screen. The TTGO also controls a servo that moves the sea urchin around. As it moves, a magnet in the urchin’s head (?) attracts the next hat.

Before settling on the current design, [rabbitcreek] experimented with both a sand dollar and a sea urchin skeleton. All the files are available if you want to whip up your own.

This isn’t [rabbitcreek]’s first foray into tide clocks. Here’s a solar number that should last for years.

What Is Killing Cursive? Ballpoints. Probably.

September 18, 2023 by Kristina Panos 225 Comments

I get it — you hate writing by hand. But have you ever considered why that is? Is it because typing is easier, faster, and more convenient here in 2023? Maybe so. All of those notwithstanding, I honestly think there’s an older reason: it’s because of the rise of ballpoint pens. And I’m not alone.

Bear with me here. Maybe you think you hate writing because you were forced to do it in school. While that may very well be, depending on your age, you probably used a regular wood-case pencil before graduating to the ballpoint pen, never experiencing the joys of the fountain pen. Well, it’s never too late.
