TV Retrofit… Because Flatscreens Just Don’t Take Up Enough Space

[Igor] helped his friend’s family out by retrofitting an old Philco television with a newer flat panel (translated). The original conked out over thirty years ago, but the look of it still held quite a bit of nostalgia for his girlfriend’s Grandmother. She showed it to him on a recent visit and asked if it could be restored. He told her that it would most likely never work again, but that he could use modern components to replace the screen, while preserving the case itself.

The best thing about old hardware like this is that you can actually get the case apart fairly easily. After removing the tube and electronics he traced a pattern of the opening that he could take along to the electronics store to find a TV which would fill the opening. With the new screen in hand he found that using the threaded holes intended for VESA mounting brackets made it simple to install in the old case. A steel bar bolts onto the plate which he cut and drilled to match the TV’s hole pattern. Now Grandma is happy to have the retro-looking case with a modern high-def picture.

Playing Snake With A TV Remote

[vinod] sent in his replica of a Snake game, the game to play on old Nokia dumb phones.

The build is based on a PIC16F877 microcontroller just like previous Snake builds we’ve seen, but [vinod] didn’t use physical buttons in his build. Instead, he used a Philips infrared TV remote to control the game. The infrared controller only takes up one pin on the microcontroller, as opposed to the 4 pins of the easiest four button setup. [vinod] also threw in a simple one-transistor level converter so Snake can be played with a PC via RS-232. With the PIC code included in the build, it’s a great build that reminds us of a more civilized age.

The video of [vinod]’s snake game in action is posted after the break, but we noticed that the snake is allowed to ‘warp around’ the sides of the LED matrix. Some people might consider that cheating but that can be fixed by changing a few lines of code.

Dumpster Hackers And Junkyard Makers Get Their Own TV Show

junkies_tv_show_science_channel

The Science Channel has a new show premiering tomorrow night that we think you won’t want to miss.

JUNKies takes a look at a group of junkyard engineers led by [Jimmy “The Junk Genius” Ruocco], who also happens to be the junkyard’s owner. From the trailer you can see below, the show looks like it will be pretty entertaining, combining the best parts of Junkyard Wars, Mythbusters, and even Jackass – with hilarious and interesting results.

The show includes crazy stuff that [Jimmy] and his crew piece together, as well as the creations of individuals that come by the shop looking for parts. When the crew is not busy concocting crazy machines, they seem more than happy to help random inventors and makers dig out just the right parts for their projects.

The show airs tomorrow night, 8/18, at 10 PM Eastern, so be sure to check it out and let us know what you think!

Automatically Weed The Celebrity Gossip Out Of Your TV Time

[Matt Richardson] came up with a doozy of an idea: using an Arduino to monitor the closed caption on TV and mute it when news about ridiculous celebrities is on-screen.

He’s using the video experimenter shield to monitor the captions. This shield connects via composite video, and can be used to decode the binary code that carries the captions in the overscan at the top of the screen. When a keyword comes through, an IR LED sends the mute command to the television, then waits until 30 seconds have gone by since the last keyword before un-muting. It’s like a troll-sniffing rat for your television! Now we just need to figure out how to use it to mute during commercials too.

[Matt] suggests we should imagine all of the cool stuff we could do with access to the closed caption data; we were already deep in thought by the time he got around to the suggestion. This would be a fantastic prank in a location were the television sound is not being used. You could put the Arduino inline with the video feed, then program it to wait for keywords in the news report and alter them in funny ways… like a live mad lib.

You can see [Matt’s] video explanation of the project after the break.

LG TV Hacking Via Serial Connection Or IR Codes

[Brendan Robert] has been sending us forum thread links outlining the things he’s learned while hacking LG televisions. They were a bit hard to follow for the uninitiated, so we asked if he could give us an overview of what he’s been working on. Not only did he do that, but he made a little Hackaday shout-out seen above by adding the skull and cross-wrenches as one of the menu overlays.

He’s using a TV as his computer monitor, which he picked up at a discount because it was a display model. Without the original remote, and wanting to have features like power-saving mode which is standard on monitors but not on this TV, he decided to see what he could accomplish. A couple of things made this quite a bit easier. First, there’s an RS232 port built into the back which removes the need to investigate and solder your own onto the board. Secondly, since LG built on the Linux kernel for the set, you can download some of the firmware sources from their website.

What he came up with is a script that will find and communicate with the TV over the serial connection. The test script used during development polled every possible command, looking for valid return values. Once [Brendan] established which commands work and what they do, he was able to take command of the unit, writing scripts to adjust brightness based on the ambient light in the room as seen from the computer’s webcam. Make sure you check out the sub-pages to his post that detail the brightness adjustments, stand-by functionality, custom overlay graphics, and the extra commands he uncovered.

Analyzing TV’s Talking Heads With Processing

[Michael] from Nootropic Design wrote in to share an interesting and fun project he put together using one of the products his company sells. The gadget in question is their “Video Experimenter” shield which was designed for the Arduino. It is typically used to allow the manipulation of composite video streams via overlays and the like, but it can also serve as a video analyzer as well.

When used for video analysis, the board lets you decode closed captioning data, which is exactly what [Michael] did here. He decided it would be fun to scrape the closed captioning information from various shows and commercials to do a little bit of content analysis.

Using a Processing sketch on his Arduino, he reads the closed captioning feed from his cable box, keeping a count of every word mentioned in the broadcast. As the show progresses, his sketch dynamically constructs a cloud that shows the most commonly used words in the video feed.

The results he gets are quite interesting, especially when he watches the nightly news, or some other broadcast with a specific target audience. We think it would be cool to run this application during a political debate or perhaps during a Hollywood awards ceremony to discover which set of speakers is the most vapid.

if you’re interested in learning more about the decoding process, [Michael] has put together a detailed explanation of how the closed captioning data can be pulled from a video stream. For those of you who just want to see the decoder in action, keep reading to see a quick video demonstration.

OnshouldersTV Knows How To Use OpenSCAD

Recently there’s been a increase in the popularity of OpenSCAD as the tool of choice in the 3d printing community. [Gavilan Steinman] is putting out a series of webTV shorts on the use of OpenSCAD. While it lacks a lot of the features of big CAD suits (such as the ability to generate drawings of your parts), the community has proven it’s effectiveness as a design tool. There are only two episodes out so far but they cover  OpenSCAD, mathcast, 3d printing, and a really neat robot design.  Watch them below.
