Video: How to Make a 3D Stereo Camera

We’re pretty used to amazing special effects — even the phone in your pocket can likely produce some pretty fancy 3D graphics. But despite this, there is a rather surprising feeling of childlike wonder whenever we view real 3D images. For many of us, the first experience was with the Viewmaster, a plastic toy which contained a disk of tiny photographic slides.

These would present two slightly different views of the same scene, taken a few inches apart, approximately the distance between our eyes. Because these images are presented separately to each eye, a 3D effect is produced.

And that’s exactly what is happening in this Wired video, featuring artist Carl Pisaturo of the nerd-robot studio Area 2881. Pisaturo’s devices are beautifully intricate, comprising a couple of 35mm film SLRs (remember those?) clamped to a stand. But what a stand. The camera bodies slide in tandem on a spacing bar and everything is designed to keep things in sync, from the three position click-stop zooms to the single shutter-trigger which fires both cameras simultaneously.

And that’s before we get to the viewers. The 35mm slides are huge compared to those in a Viewmaster, and the viewing devices reflect that. The engineering is precise, but what gets us is the look of these things — somewhere between steampunk and a kid’s toy playset. Beautiful.

How to Shoot (and View) 3-D Photos [Wired Video]

LaserPup trains for battle with Laser Cats

We don’t really know where to begin. LaserPup involves shooting a laser at a dog over the internet, nothing more, nothing less, but somehow it transcends traditionally pointless moddery and becomes something so much greater. Maybe it’s because you shoot a dog with a laser over the internet. LaserPup is a ceiling-mounted laser and webcam whose beam can be directed around the floor with an iPhone-friendly browser-based interface. There’s switch for turning on and off the lights, and when the laser is activated or deactivated it makes a sound to alert the dog that it’s time to get shot at by lasers. In the future, there was a nuclear war… video is after the break.

Wiimote modded with terrifically minor results


Remember DHRECK, the modder who modded a Wiimote by covering it in hemp and calling it a day? Well, he’s back, and this time he’s made one that’s slightly smaller than the original. That’s right: not totally teeny, or miniaturized (it’s not lethal, either) — just somewhat smaller than an actual, unmodified ‘mote. He’s made some other minor cosmetic changes to it as well, and the results are attractive. Check the gallery of fantastic photos after the break.

[Thanks, John]

D.I.Y. motion-controlled MP3 player doesn’t need your fancy touch screen

Our anonymous engineer friend over in Ageo, Japan sure loves to make him some gadgets — among his many projects he’s already built a couple other MP3 players, and now he’s back with a tiny, motion controlled device that plays tunes from an SD card. Housed in a set of speakers (switching from stereo to mono when the satellite is unplugged) this thing uses an accelerometer for its interface: the user can skip ahead, skip back, change albums, pause, loop, turn down or crank up the sound by tilting, tapping, or setting the thing down. This is a strictly D.I.Y. affair, so if you want to get your hands on one you’ll have to hit the read link for the parts list, schematics and firmware. Captured on video after the break.

DIYers Get a Treat With Top 40 Arduino Projects

Arduino_keyboard

Open source programming platform Arduino has spawned thousands of enthusiastic DIY-gadget heads.

The Arduino board, with its "Made in Italy" tag, features a microcontroller that can be programmed for a number of projects using a custom programming language and development environment. It’s useful for simple robotics and electronics projects that need a little more intelligence than you can get with a handful of resistors and capacitors from Radio Shack — which is why it has become an underground hit among true gadget enthusiasts.

Now Hack N Mod has scoured the web to find the top 40 Arduino projects. The list includes projects to make a robot that will avoid walls, a twittering plant, a miniature pocket piano, a Segway-like robot and an interactive gaming controller–all using Arduino. Wired magazine editor-in-chief Chris Anderson’s make-your-own unmanned aerial vehicle (UAV) or spyplane gets the second spot on the list.

The list of the 40 projects comes with instructions on how to get started on each. Now there’s no excuse to hang out in the garage and just drink beer on the weekends. Its time to get tinkering.

How To Shoot Video With the Nikon D700

This clunky little workaround will let you shoot video with the Nikon D700. In fact, it will work for any camera which can pump a live video stream into a computer. It has nothing to do with the rather nice, and rather higher definition hack we covered earlier today, but it will let you at least play with the great lenses and shallow depth of field afforded by DSLR videography.

This hack uses three ingredients. First, a camera with a live view function, which lets you see a real-time stream on the camera’s screen. Every single compact camera does this, and more and more DSLRs provide the feature. Second, a way to get the feed from the camera to the computer. I used a trial version of Nikon’s Camera Control 2, a truly awful piece of non-intuitive software that just manages to get the job done. Third is a way to capture the video displayed on the screen. For this I used iShowU HD Pro, a screencasting application for the Mac.

Picture_1

First, connect the camera via USB cable and fire up Nikon Capture (or software of choice). At bottom right you see the button marked "Lv", or Live View. Click this and the camera will start sending a low quality video feed to the computer (you can click to make the picture bigger):

Liveviewcapture

Next, fire up your video capture application, in this case iShowU. If you can, set it to capture only the part of the screen you actually want, otherwise you’ll have to take the video file into an editor to crop it later:

Ishowselection_2

Once done, hit return and start the recording. Anything you now do with the camera is being recorded. Here’s the result. It’s pretty poor, and because I’m using the trial version there’s an overlay watermark from iShowU. But you get the idea.

The quality is severely limited by the refresh rate of the incoming video feed, although the D700 has an HDMI out port, so this could be used to get a much better stream. What is interesting is that you can see just how useless live view is even for still capture — the focusing takes forever in any mode.

As an exercise, this is fun, but ultimately the quality is too poor for anything — on a Mac it would be better to just use the iSight camera to shoot. Still, if you have the camera, the trial software is free so go and try it out.

Scrabble Keyboard: Never Be Stuck With Only Vowels Again

scrabble1.jpg

Hey, Scrabble geeks-even if you can’t play the addictive game 24/7, at least you can pretend with the Scrabble keyboard. Although not (yet) for sale, the Scrabble keyboard is made from real Scrabble tiles that were all hand-beveled and built into a USB, clicky, mechanical-switch keyboard. Granted, not all of the keys, like the Caps lock key, are original Scrabble pieces, but for the most part, the keys are authentic.

The keyboard’s creator received such a positive response, that a note was added on Jan. 19 saying a batch of keyboards is being considered for the near future. The legality of the Scrabble name could be an issue. “Please don’t sue me, Hasbro, I’m just a guy in a garage over here!” said the keyboard’s creator.

Here’s hoping Hasbro lets him make more of those keyboards, because playing online Scrabble with the Scrabble keyboard would make it just that much more fun.

Doc Datamancer’s Scrabble Keyboard Gets Triple Word Score

Scrabble

This amazing Scrabble keyboard comes to us by way of BoingBoing Gadgets’ John Brownlee who, in the course of describing Doc Datamancer’s steampunk hack, makes some startling admissions.

Those of you familiar with his work might expect a smattering of references to wet bodily functions, or at least some show-off allusions to the works of Vladimir Nabokov. You would, just this once, be disappointed. Instead, Mr. Brownlee gives us a revealing insight into his writing process, something which turns out to be far more complex than just letting dolphins push balls printed with random words to the top of their tank and copying the result — our previous assumption:

[W]riting is not about randomly shaking up a tray of letters in one’s head and plucking words from the alphabetical mnemonic slurry… if it was, my posts would make more sense. [emphasis added]

As somebody who has spent time with Brownlee in his Berlin bachelor pad, this is thick with irony. He actually owns a Scrabble set which he keeps at his desk. And while he doesn’t shake the letters "in his head", he invites his neglected parakeet to peck at the tiles, thus outlining post after post. It’s a testament to the bird’s uncanny language skills that we understand the man at all.

Student charts electrical usage in real-time, much to Big Brother’s delight

It’s our best guess that University of Florida PhD student Jason Winters woke up at 10:00AM ET this morning and took an approximately 18-minute shower. How did we come to this conclusion? Using an AC clamp attached to an ioBridge, the biomedical engineering scholar measures the main electrical lines entering his house and sends the data to a Google charts widget on his personal blog that reports the kilowatt-hour usage in real time. As a footnote, he presents an example graph of when the hot water is turned on, which then produces close to 4500 watts. That’s just over the amount of power he used this morning for about 1100 seconds. Of course, we can’t say for certain any of these morning events really transpired, but then again, we don’t exactly want to know. Hit up the read links for directions on DIYing this.

Handcrafted Scrabble keyboard could stand to be commercialized

Um, can you say “sell like hotcakes?” Datamancer‘s incredibly amazing Scrabble keyboard is one of the slickest, most ready-for-market DIY projects we’ve ever had the pleasure of eying, with each letter key being constructed from an actual pre-owned Scrabble game piece. The USB keyboard itself was built with an aluminum casing for an “industrialized twist,” but obviously it’s the top that keeps us drooling. Oh, and there are even LEDs hidden beneath the Num Lock, Caps Lock and Scroll Lock keys, suggesting that a completely backlit iteration isn’t too far out of the realm of possibility. A few more images are tucked away in the read link — you owe it to yourself to check ’em out.
