Senko [Flash]

Tatsu Iida, a member of oxoxo [zero by zero] wrote in to tell us about the interactive LED installation entitled Senko [Flash] which they showed at the Tokushima LED Art Festival in April.

They used a Peggy 2 to drive a field full of LED illuminated spheres, along with IR sensors to detect visitors entering the array. Each new person would trigger a new sphere to light up and move through the field.

Some of the creations are more technical, like the OpenPNP project to create open source pick and place machines for electronics assembly.  We’re excited by where this is headed, along with a few related projects.

RoboGames 2013 Medals

Robogames_2013 35

We helped build the gold, silver, and bronze medals for this year’s RoboGames competition, which finished up yesterday in San Mateo, California.

Read on for a bit about how we designed and built the electronics for, and assembled these pretty-darned neat medals.  It’s a story involving LEDs, some remarkable adhesives, and a how to operate a small-scale surface mount production.

Dazzle Camouflage in Fashion

We’re no strangers to seeing an occasional hard-to-look-at article of clothing. However, we recently came across the above pictured dress (the Signature Shift Dress by Julie Brown), and noticed a peculiar quality about it.  The pattern of angled, high-contrast shapes makes it remarkably difficult to see the actual shape of the dress underneath that print.

Now, where have we seen this kind of thing before?

Ah yes: Dazzle Camouflage!  Dazzle camouflage was used in WWI to make ships more difficult to identify and target, by disguising their size, configuration, range and orientation. This is different from traditional camouflage, which tries only to minimize visibility, but can be surprisingly effective.  In the photo above, of the USS Mahomet in port (circa November 1918), it’s hard to make out even the out the shape of the ship.

Additional good examples of ships with dazzle camouflage can be seen herehere, and here (in an article that discusses the design process for the patterns).

Curiously, dazzle camouflage seems to have made a recent comeback in fashion.

This Print Wrap dress at Uupto distorts the model’s curves in strange ways.  Thanks to the “mountain range” in the middle, one might initially perceive this to be a maternity dress.

The Print and Proper dress at Modcloth is another new example.

And the Poleci Women’s Cross Front Striped Longsleeve Top from FavBuy creates the illusion of a strangely misshapen abdomen.

The Elbow Sleeve Tiered Dress at Venus.  The interrupted, striped, spiraling pattern creates the illusion (perhaps assisted by photoshop) that the diameter of the dress is somewhat smaller than it is in reality.

You can dazzle all the way to your toes, with these matching Black and White Platform Heels at Venus.

 

Some designs stray from simple black and white geometric patterns, but still effectlively confuse the eye, such as this Jersey Maxi Dress by Julie Brown.  Worth noting is that many of the original dazzle patterns on ships were brightly colored, too.

 

Of course, this is not the first time dazzle camouflage has appeared in fashion. At the time that dazzle camouflage was first introduced, the public was fascinated by it.

The Dazzle Camouflage Pinboard by user Saruzza has some wonderful historical fashion examples, including a reference to a 1919 Dazzle Ball at the Chelsea Club.

From a contemporary article (via camoupedia), comes this account:

Four British naval officers, distinguished for their success at camouflage, had charge of designing the dresses, and the ballroom looked like the Grant Fleet with all its warpaint on, ready for action. The jazz bands produced sounds that have the same effect upon the ear as this “disruptive coloration” has upon the eye.

A themed masquerade ball is one thing, but the patterns did also make their way into the mainstream culture of the time:

This picture of dazzle camouflage bathing suits from the 1919 New York Tribune was provided as a visual supplement to an excellent audio post by 99% Invisible on disruptive camouflage.

And as for the future? No discussion of dazzle would be complete with out mentioning CV Dazzle, which covers methods of using makeup and hairstyles to thwart face recognition software. Perhaps soon e-ink fabrics will also provide changeable displays that disrupt QR and barcode readers, as well as other visual tracking systems.

Infra, a TV built from remote controls

Chris Shen‘s first solo show just opened at 18 Hewett Street in London, and he shared with us about his piece, Infra, built using a Peggy 2:

The idea was to build a infrared display out of old remote controls, using the existing infrared LEDs as pixels of a low-res display. 625 old remote controls are mounted in a metal frame connected by individual wires to a modified Peggy 2 that runs the whole installation.

The main change to the Peggy was to solder molex headers instead of LEDs: this is to allow the wires to be easily plugged in and out of the board which is necessary when dismantling and reassembling the piece. Yes, all 625 remotes are numbered so they can be removed from the frame for transportation! The current and voltage was also adjusted fo IR LEDs as opposed to visible LEDs.

While researching, the main thing I was looking for was the ability to play video (live) on a low-res matrix. I looked into various ways of doing this but once I found the Peggy 2 kit it gave me confidence to go ahead with building Infra because of the open-source nature,  existing work done by Windell, and Jay Clegg’s video Peggy mod.

I connect all the remote controls via 500 meters of speaker wire to the Peggy, held into the frame by a simple looped elastic band. The circuit is mounted to a sheet of acrylic as the circuit bowed with all the wire attached. Each remote had to be opened to solder the wire directly to the LEDs legs. The wire is then routed out through the back of the remote and closed back up.

Preparing all 625 remote controls was the most time consuming part, each was different and often not very clean especially once you get inside. Although looking at all of the remotes individually revealed another side to the project which I’ve documented through a small run of books.

Thank you to Chris for sharing about how you made your piece with us. His exhibit will be up through February 3rd, 2013, so if you’re in London, go see it soon!

Another wild Peggy 2 project: Heddatron Robot

The folks at Chibots helped the Sideshow Theatre with building the robots for their 2011 production of Heddatron that was part of the Steppenwolf Garage Rep series. For the character Billy Bot, they used a Peggy 2 as a chest display panel which could be controlled remotely along with the rest of the robot actions and behaviors during the performance.

Don from Chibots wrote:

I got to assemble it (625 LEDs!), and made some modifications to the control circuitry to accommodate needs of the remote controls.  The robots were controlled via X-Bee Pro radio transceivers coupled to BahBot MCU boards. Of course, the solidly-designed Peggy 2 worked perfectly out of the box.

The production won a Jeff Award in the Artistic Specialization category for Outstanding Achievement in Robot Design and Engineering.

Billy Bot was even called on to help with a surprise wedding proposal after one of the shows, and you can see him in action briefly in the video above.

Awesome robot work, Chibots!

Puzzle Kickstarter is a Puzzle

Roy Leban of Puzzazz, a puzzle company, is running a Kickstarter campaign for a puzzle a month for a year. The unique thing about this campaign is that it is itself a puzzle. The project video includes a whole bunch of clues related to interesting and geeky people like Theodore Gray, Nolan Bushnell, and (gasp) me! The Kickstarter puzzle is free to everyone, whether or not you’re backing the project. However, if you like the puzzle, you may want to help out the project to get the full year of puzzles!

Interactive LED Bar

Interactive LED Bar

Alter Itay sent us pictures of a bar he designed with our Interactive LED Panels installed under the glass bar top.

Empty bar

This is a popular use for the panels, but we rarely get to see the end results, as the bars they get installed in are all over the world.

People interacting

As the patrons interact with each other and the bartenders they trigger the sensors and their drinks are illuminated by the LEDs.

Interactivity in action

Thanks very much to Itay for sending us the pictures and letting us share them!
