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’.

TV Hack Bypasses HDCP

October 1, 2009 by 64 Comments

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.

Build An Analog TV Station

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.

Apple TV With Boxee And More Update

atvusb-creator

In November, we covered installing Boxee on AppleTV using atv-usb-creator. [Danny] has written a tutorial on installing Boxee, XBMC, NitoTV, SSH access, and external USB hard drive support. His method installs most of the software via the USB patch stick, then uses the SSH support to enable the external drive and install NitoTV. The tutorial lists a Mac running OSX 10.4 or newer as a prerequisite but there is now a Windows version of atv-usb-creator. According to their Google Code page Linux support for this package is on the way.

Hacking The Western Digital TV Media Player

August 25, 2009 by 32 Comments

Western Digital recently released a media player that attaches to your TV and allows you to play HD media straight from an external USB drive to the television. With a price point of about $100, it’s strange that the device hasn’t made more of a stir in the consumer electronics market. Of course, if it exists, someone will hack it, though. Clever hardware and software hackers have already managed to get an alternative firmware running on the device, allowing for packages like a web server, RSS reader, Apple trailer viewer, and other linux-based packages. It’s good to see a device with so many software mods so early into production.

Adafruit Releases New TV-B-Gone Kit

August 17, 2009 by 54 Comments

Recently, our friends over at Adafruit released a new version of their popular TV-B-Gone kit. Built in cooperation with [Mitch Altman], the inventor of the TV-B-Gone, the new kit sports four high power IR LEDs, two wide beam and two narrow beam. The four LEDs give the new TV-B-Gone increased range, with a maximum distance of over 150ft. One of the most impressive features of the kit is the fact that the new TV-B-Gone is universal and can now work in Europe and Asia in addition to the US. Users are able to select which region they want to use during the build process by soldering a resistor into the board at their region’s corresponding spot as seen in the picture above. The new TV-B-Gone kit is now available in the Adafruit store for $19.95 plus shipping.

World Smallest TV-B-Gone

The TV-B-Gone has proven to be a dangerous and versatile gadget. At Interactive Matter, they created an even smaller version with more sneaking potential. Called the µTVBG, it packs an entire TV-B-Gone in a 1.4 x 2.5 cm footprint and even has room for a programming header. He found some high-powered surface-mount IR LEDs that would match the original TV-B-Gone’s power. To drive the board, they used a CR1220 button battery on the bottom of the board. The whole thing is smaller than your thumb and should be easier to hide next time you wreak havoc.
