This is not a hack. In fact it’s a promotional montage for a collection of scientific equipment that few of us could likely afford. But like yesterday’s giant marionettes over Berlin, sometimes even a costly and delicately-orchestrated achievement transcends its own not-a-hack-ness, fulfilling our brains’ lust for wonderment all the same.

Kurzzeit of Germany produces ballistics measurement equipment. The video depicts various combinations of projectiles and targets at up to one million frames per second, revealing unexpected beauty in hitherto unseen phenomena, and is the best damn ten minutes you will waste on the internet all day!

TV-B-Gone: antisocial nuisance or harmless prank? Whatever your feelings, there’s no denying this device has become a staple of the DIY hacking crowd, as evidenced by the countless derivatives since hatched. This latest mutation crushes them all.

[manekinen] from the Polish electronics blog Elektroda (“Electrode”) wasn’t satisfied with high-power TV-B-Gone designs using multiple 5mm infrared LEDs, so he created his own using a single one-Watt monster. The device is concealed in an ordinary flashlight casing, making it somewhat inconspicuous. A custom PCB containing an ultra-minimalist version of the TV-B-Gone circuitry sits just behind the reflector. The choice of reflectors determined maximum distance vs. coverage…they opted for distance. Specific figures aren’t given, but we estimate this thing could shut off televisions on Mars.

The original article (Polish or Google-ized English) includes construction photos and an archive (.rar) of project files including Eagle schematics and C source code.

Would it be totally irresponsible to mention there’s now a 3-Watt version of this LED? We’re just sayin’.

[banzai] wasn’t happy with the performance he was getting out of his Samsung netbook. He decided it was time to do something about it. He noticed that Dell and HP both sell an optional HD decoder card for their netbooks. After a short search, he found one on ebay for only $24. He had to give up his internal wireless, but he doesn’t mind using a USB wireless dongle. Sure this isn’t horribly complicated, but he has information here that might help smooth out the process.

In August we covered a wireless electricity presentation from the TED conference. Now Sony has put out a press release on their wireless flat panel television prototype. The device is capable of operating without audio, video, or power cables connected to it. This is possible at distances up to 50cm at efficiencies as high as 80%.

As was talked about in the comments of the other article, the efficiency compared to that of a cable doesn’t blow our socks off. But this does show mainstream development of this technology. We hope to see advances in both efficiency and distance. We also look forward to that small black box (which we presume facilitates the energy transfer) being integrated into the TV’s body.

Reader [GRitchie] wrote in with an interesting find in his new TV set: with just some minor soldering it was possible to tap into an unencrypted hi-def video stream.

HDCP (High-bandwidth Digital Content Protection), used by Blu-Ray players and cable or satellite receivers, normally ensures a DRM-protected link between the device and a compatible display. Any properly-licensed device that forwards HDCP content (such as an HDMI switch box) is expected to provide encrypted output; those that don’t may get blacklisted by the system and become expensive paperweights. It’s something of an annoyance for users who feel this oversteps fair use applications such as time-shifting.

[GRitchie] found that his new TV with “InstaPort” Fast HDMI Switching didn’t perform this re-encryption step between the set’s internal switcher and the next stage in decoding. Soldering just eight wires directly from the switching chip’s output to an HDMI cable provided an unencrypted output that could then be received by a PC for later replay.

What’s not clear at this point is whether the capability is peculiar to just this one make and model, or applies to anything with the new Fast HDMI Switching. If the latter, it will be interesting to see how this plays out…nearly all of the major HDTV manufacturers are evaluating InstaPort for new sets, which would make any attempt at HDCP blacklisting awkward, to say the least.

We were momentarily excited when we heard that CableCARD compatible tuners will be available for purchase by the end of the year. A card like this would allow you to hook up your digital cable to your computer and record programs natively. This has been possible for a long time with analog cable and PVR software such as MythTV. Up to this point, recording digital cable has required a dedicated cable box and workarounds to allow the computer to change channels.

Wait a minute though, the announcement was made by Microsoft? Indeed. Microsoft has been making a big push into the home theater PC market with Media Center. Redmond’s PVR offering is also limited to recording analog television;opening up digital would expand the marketplace for them. But here’s where it gets hairy: if you read the Microsoft announcement, TV shows flagged as CF (copy freely) are the only ones that can be recorded.

So, if we have this right:  you shell out money for a new tuner then you pay more for the rental of the CableCARD. Both of these expenditures are on top of a digital cable subscription. And yet you can only record shows marked with a “Copy Freely” flag. Who makes the decision on which shows we can pay to record?

Everyone’s favorite open source game console, the Uzebox (also cloned as the Fuzebox), just got a new feature hacked into it – a video player. At reduced quality (8-bit color), the Uzebox was able to play ‘The Matrix’ off an SD card @ 30fps plus the audio @15kHz. That’s a pretty impressive feat when one considers it is running on 4096 bytes of RAM. The video file had to first be converted into a series of pictures through a Photoshop macro in order to be playable. A Uzebox can be built with little more than a few resistors in addition to an overclocked ATmega644P, and AD725 (which has been skirted in certain incarnations).

[Marco Tempest] has developed some software called MultiVid that allows synchronized video across multiple iPhone or iPod Touch devices. For this to work, all of the devices must be connected to the same WiFi network. Playback can be controlled from any one of the iPhones/iPod Touches or from the Mac running the controller software. There is of course the option of connecting to larger monitors through a video output cable. The app also supports OSC. We’ve embedded the example video as well as a video detailing the software setup after the break.

The client software is available at the apps store and controller software can be downloaded from [Marco's] website. Both are free which is our favorite price point.

Update 9/6/09: We contacted Marco because this app was MIA from the App Store. He responded promptly to let us know that his app is “still in approval limbo”. He’s going to contact us when it is approved and we’ll be sure to pass on the update to you.

With the transition to digital TV, the FCC has abandoned the old analog format. Luckily, you can take advantage of this and set up your own analog TV station. The FCC has a tool on their site to see what channels are open in your area to broadcast in. To broadcast, you need a TV transmitter, but cheap short-range models can be found on eBay or made at home [pdf]. Once you have a transmitter, you can pump in a video source, either your own content or videos from youtube. One group, OMGimontv is showcasing popular youtube clips on channel 14 in New York. On their site, users can vote for what clips they want to see. Although this isn’t as simple as making a radio station, it still has a lot of potential.

National Geographic has pegged September 2, 2009 as the 40th anniversary of the Internet. They do not cite their source and our source doesn’t make the same claim. But, August 30, 1969 is the date the first Interface Message Processor was delivered to the Arpanet. The IMP is what allowed different computer networks to talk to each other and so it follows that September 2 is probably an acceptable date to celebrate.

To commemorate this glorious day we’re sharing some of our favorite History of the Internet videos. Start with the National Geographic video and then take in the geeky, the new, the old, and the simple.

The Geeky:

[Ethan Zuckerman] walks us through the history as only a geek could. This video starts off with a picture of the guys who invented the IMP which is what facilitated the first information transfer between networks (the Internet). “The Internet as we know it came into being in 1969″.

The New:

A fairly brilliant video presentation of how the Internet developed from several smaller networking projects. Accessible to experts and novices alike.

The Old:

A CBC news report on “The growing phenomenon of: Internet” made in the pre-broadband days. It’s interesting that “the” is missing when they refer to “The Internet”. At 3:25 you can see a lengthy description of what those new-fangled emoticons are all about.

The Simple:

A short animated video that explains IP addresses and how a computer connects to the internet through a service provider.

[Eric Giler] has a talk available over at TED that discusses and demos delivering electricity without wires. Called WiTricity, these methods were developed by a team at MIT a few years ago who were working off of the concepts of Nicolai Tesla. The facts shared about our current energy delivery system are a bit shocking; we’ve spent over $1 trillion in infrastructure and produce more than 40 billion disposable batteries each year.

The demonstration in the video starts about 6:30 into it. At first we see a flat panel television powered wirelessly from about 6 feet away, then the T-Mobile G1 powered from the same distance. The thought of new TVs coming with WiFi and WiTricity standard would mean just hanging it on the wall with no cords to run. We can also image cellphones that have a battery only for backup purposes when you were not near a transmitter.

The power transfer occurs between two coils that resonate at the same frequency and only that frequency. This remind us a bit of Orson Scott Card’s fantasy communications device from the Ender’s Saga.

In this video you can see the marriage of Arduino data collecting units and Augmented reality systems. Set up by the people at pachube.com, a site for sharing sensor information from your location, this is an interesting idea. We can see that each unit has its own pattern, so it can have the data it is collecting superimposed on it in 3d. While this is really cool looking, we’re still trying to figure out what the use of this is? Who is going to be wandering around their office with a camera hooked to a computer? Maybe this is meant more for phones, so you can get quick readings off of the units without having to go access their logs. Since we know how much you guys absolutely love the Arduino, we though you might also be interested in this larger than life portrait we saw floating around.

Among the courses at this year’s SIGGRAPH (an annual technical conference and showcase of the latest in computer graphics research) was an introduction to 3D scanning that covers all the bases: mathematical foundations, two different build-your-own hardware approaches, and how to process and render the resulting datasets. The presenters have assembled all the course materials on a top-notch web site featuring slide shows, complete source code, and an extensive round-up with links to both commercial and homebrew 3D scanning gear. The simplest of these methods requires nothing more than a webcam, halogen light source, and a stick!

SIGGRAPH and 3D scanning have been highlighted many times on Hack a Day, but we’re swelling with pride now seeing an academic venue give a favorable nod to the DIY hacking community (on their links page). Okay, so Hack a Day isn’t called out by name, but just wait’ll next year!

Reader [Jani] always wanted to throw a PC into an old school cell phone. He based this around the extremely small Commell LS-371 motherboard which measures just 146×101 mm (~5.9×4 in). He found room behind an existing access door for a DVI connector and audio in/out.  He even incorporated an OLED screen, secondary sound card for “speakerphone”, and a WiFi connector into the handset. Things start to get interesting when he decided the SSD was too large and needed to be removed from its case. The one thing that seems to be missing here is an IR receiver for a remote but since he plans on running XBMC, he may already be setup to use another option such as an iPhone to act as a remote interface.

[Dave Vondle] from IDEO Labs sent in the large LED pixel wall he built using BlinkM modules, an Arduino, and Flash to control it. The overall result is a blindingly bright, large, public display for people to interact with. The best part about the project is that [Dave Vondle] documents everything; from hardware to schematics to source code. Unfortunately, he was forced to remove the wall due to construction, but since every part of the project is open source, it lends itself to be easily recreated. I’m sure we’d all like to see a wireless controller hookup to play pong on the streets of Chicago.
