A Tool For KiCad Board Renderings

Posted on by

If you’re producing documentation for a PCB project, you might as well make the board renders look good. But then, that’s a lot of work and you’re not an artist. Enter [Jan]’s new tool that takes KiCad board files, replaces each footprint with (custom) graphics, and provides a nice SVG representation, ready for labelling. If you like the output of a Fritzing layout, but have higher expectations of the PCB tool, this is just the ticket.

We all love [pighixx]’s pinout diagrams. Here’s his take on the Arduino Uno, for instance. It turns out that he does these largely by …read more

An Interactive Oasis At Burning Man

Posted on by

An oasis in the desert is the quintessential image of salvation for the wearied wayfarer. At Burning Man 2016, Grove — ten biofeedback tree sculptures — provided a similar, interactive respite from the festival. Each tree has over two thousand LEDs, dozens of feet of steel tube, two Teensy boards used by the custom breath sensors to create festival magic.

Grove works like this: at your approach — detected by dual IR sensors — a mechanical flower blooms, meant to prompt investigation. As you lean close, the breath sensors in the daffodil-like flower detect whether you’re inhaling or exhaling, translating …read more

MIDI Drawings Paint with Piano Keyboards

Posted on by

Musician [Mari Lesteberg] is making music that paints pictures. Or maybe she’s making pictures that paint music. It’s complicated. Check out the video (embedded below) and you’ll see what we mean. The result is half Chinese scroll painting, and half musical score, and they go great together.

Lots of MIDI recorders/players use the piano roll as a model for input — time scrolls off to the side, and a few illuminated pixels represent a note played. She’s using the pixels to paint pictures as well: waves on a cartoon river make an up-and-down arpeggio. That’s a (musical) hack. And she’s …read more

Creepy Speaking Neural Networks

Posted on by

Tech artist [Alexander Reben] has shared some work in progress with us. It’s a neural network trained on various famous peoples’ speech (YouTube, embedded below). [Alexander]’s artistic goal is to capture the “soul” of a person’s voice, in much the same way as death masks of centuries past. Of course, listening to [Alexander]’s Rob Boss is no substitute for actually watching an old Bob Ross tape — indeed it never even manages to say “happy little trees” — but it is certainly recognizable as the man himself, and now we can generate an infinite amount of his patter.

Behind the …read more

Light-Painting Robot Turns any Floor into Art

Posted on by

Is [SpongeBob SquarePants] art? Opinions will differ, but there’s little doubt about how cool it is to render a pixel-mapped time-lapse portrait of Bikini Bottom’s most famous native son with a roving light painting robot.

Inspired by the recent trend of long exposure pictures of light-adorned Roombas in darkened rooms, [Hacker House] decided to go one step beyond and make a lighted robot with less random navigational tendencies. A 3D-printed frame and wheels carries a pair of steppers and a Raspberry Pi. An 8×8 Neopixel matrix on top provides the light. The software is capable of rendering both simple vector …read more

Morbid Battery Uses Blood Electrolyte

Posted on by

Building a battery out of common household products is actually pretty simple. All that is required is two dissimilar metals and some sort of electrolyte to facility the transfer of charge. A popular grade school science experiment demonstrates this fairly well by using copper and zinc plates set inside a potato or a lemon. Almost anything can be used as the charge transfer medium, as [dmitry] demonstrates by creating a rather macabre battery using his own blood.

The battery was part of an art and science exhibition but it probably wouldn’t be sustainable on a large scale, as it took …read more

This Art Project’s Video is Not a Time-Lapse

Posted on by

Artist Pe Lang uses linear polarization filters to create an unusual effect in his piece polarization | nº 1. The piece consists of a large number of discs made from polarizing film that partially overlap each other at the edges. Motors turn these discs slowly, and in the process the overlapping portions go from clear to opaque black and back again.

The disc rotation speed may be low but the individual transitions occur quite abruptly. Seeing a large number of the individual discs transitioning in a chaotic pattern — but at a steady rate — is a strange visual …read more
