TV-B-Gone-zilla! Rawr!

tv-zilla

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’.

Hardware HD Decoder In A Netbook

[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.

Sony’s Wireless Electricity Offering

October 3, 2009 by Mike Szczys 45 Comments

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.

TV Hack Bypasses HDCP

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.

CableCard Card Tuners On The Way

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?

Uzebox Video Player

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).

Multi-screen Video With Ipod

[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.
