With apologies to Clement Clarke Moore, Richard Stallman, and the English-speaking world in general — ed.
‘Twas the night before Christmas
While up in my bed,
I stared at the ceiling
With feelings of dread.
I’d really no reason for portents of doom
Lying there, sleepless, in gathering gloom.
We’d wrapped all the presents, and decked out the tree,
But still, there was something niggling at me.

Hackaday gets results! Reader [John] saw our recent Fail of the Week post about a “sand matrix printer” and decided to share his own version, a sand-dispensing dot matrix printer he built last year.
Granted, [John]’s version is almost the exact opposite of [Vjie Miller]’s failed build, which sought to make depressions in the sand to print characters. [John]’s Sandscript takes a hopper full of dry, clean sand and dispenses small piles from six small servo-controlled nozzles. The hopper is mounted on a wheeled frame, and an optical encoder on one wheel senses forward motion to determine when to open each nozzle. As [John] slowly walks behind and to the side of the cart, a line of verse is slowly drizzled out onto the pavement. See it in action in the video below.
More performance art piece than anything else, we can see how this would be really engaging, with people following along like kids after the [Pied Piper], waiting to find out what the full message is. There’s probably a statement in there about the impermanence of art and the fleeting nature of existence, but we just think it’s a really cool build.
We’ve featured other sand writers before, like this high-resolution draw bot that also dispenses sandy verses, or this literal beach-combing art bot. Guess there’s just something about sand that inspires artists and hackers alike.

When [::vtol::] wants to generate random numbers he doesn’t simply type rand() into his Arduino IDE, no, he builds a piece of art. It all starts with a knob, presumably connected to a potentiometer, which sets a frequency. An Arduino UNO takes the reading and generates a tone for an upward-facing speaker. A tiny ball bounces on that speaker where it occasionally collides with a piezoelectric element. The intervals between collisions become our sufficiently random number.
The generated number travels up the Rube Goldberg-esque machine to an LCD mounted at the top where a word, corresponding to our generated number, is displayed. As long as the button is held, a tone will continue to sound and words will be generated so poetry pours forth.
If this take on beat poetry doesn’t suit you, the construction of the Ball-O-Bol has an aesthetic quality that’s eye-catching, whereas projects like his Tape-Head Robot That Listens to the Floor and 8-Bit Digital Photo Gun showed the electronic guts front and center with their own appeal.

Artists see the same world that the rest of us do. They just see it from a little bit off to the left. Where you see picking an ESSID for your router as being a hassle, or an opportunity to insult your neighbors, [Dmitry], alias [::vtol::] sees a poetry-delivery mechanism.
Based on ESP8266 units, each “poet” has a battery and a switch. Turn it on and it changes its SSID once every ten seconds, feeding everyone who’s listening the next line of a poem. You can’t connect to the network, but you can occasionally hit refresh on your WiFi scanner and read along.
Since they’re so cheap to build, [::vtol::] sees them almost as if they were poetry-throwies. You could easily afford to leave a few around the city, guerilla-style, broadcasting your (slow) message one SSID at a time. We love the video clips (inlined below) of him riding the subway with the device on.
