With our busy lives, who has time to pay attention to TV show schedules? [Tamberg] certainly didn’t and that is why he came up with the web-enabled TV remove he calls the Smart Homer. This miraculous device knows when ‘The Simpsons’ is being broadcast, turns on the TV and switches to the appropriate channel.
Like the real Homer, not too much is going on up in this toy’s noggin. A couple of IR emitters are mounted in place of pupils and the associated wires are run down into his body. Right between a pink donut and a Krusty burger resides an Arduino and ethernet shield. This electronic duo acts as a web server and looks out to the ‘net for an online script. The script polls an online TV Program Guide and if ‘The Simpsons’ are on at that time, it sends a signal back to the Arduino to turn the TV on.
There are a lot of options out today for streaming video to your Internet-connected devices. Whether it’s Hulu, Netflix, Slingbox, or the late Aereo, there is no shortage of ways to get your TV fix. However, [Jaruzel] wasn’t happy with any of these services and wanted a more custom solution, so he built his own TV-streaming box out of hardware he had lying around.
[Jaruzel] gets TV from a service called SkyTV, but wanted to be able to stream it to his tablet, laptop, and XBMC. While rummaging through his parts bin, he came up with a WinTV tuner card for capturing TV and a Mini-ITX board to process everything and stream it out over his network.
Once the computer was put in a custom enclosure, [Jaruzel] got to work installing Puppy Linux. He wrote a boot script that configures the WinTV card and then starts VLC to handle the streaming service which allows him to view the TV stream over HTTP on the network. This is a great hack that would presumably work for any TV stream you can find, even if it’s just an over-the-air source.
Would you believe that some people think the internet is a time waster? Well, not at this particular address of course, but we can think of some other sites that are absolute rabbit holes without so much as a rousing game of croquet at the bottom. If you need help achieving what Tim Ferriss dubbed a Low Information Diet, there are browser extensions that will block your access to sites that keep you from getting things done. [Ivan’s girlfriend] has taken this time management tack seriously and even created a simple web page that states “Don’t Waste Your Time!” that will show if she tries to get to Facebook.
There’s one small problem with all this, and it’s been around for a long time. [Ivan’s girlfriend] still watches TV. Out of love and respect for her goals, he decided to prank her by blocking her TV viewing. In a delightful twist, the TV will display her own web page to her after 30 seconds.
They have digital and analog TVs, so he had to set up both in order to cover his bases. The digital TV is a monitor fed from a set-top box with HDMI out. As the STB can only be controlled via IR remote, [Ivan] used an HDMI switch to change from the STB input to a Raspi that will display the reprimanding web page and play Pink Floyd’s “Time“.
The analog TV took slightly more doing. He put a Raspi on the AV input, but connected it from the inside so nothing looked suspicious. The Raspi checks the TV status every second and switches to the Pi once the TV is on. Same deal: judgmental web page, Pink Floyd. The beauty part is that both of [Ivan]’s setups also record her reaction; the digital TV uses a dash camera and the analog uses an Android phone. Check out [Ivan]’s tour of the analog TV Pi after the break.
If you or [Ivan’s girlfriend] need even more time management help, there’s always the roll-your-own-Pomodoro timer.

There’s a lot of cool stuff to be found under piles of trash in an antique store. [dijt] discovered this when he found a tiny 7″ Motorola television from the 1940s under a stack of trinkets from earlier eras. We can understand [dijt]’s impulse buy, and the trials of rebuilding this ancient TV more than qualifies it as a hack.
If you know where to look, there are hundreds of resources available for old televisions, Hi-Fis, and radio equipment from the dawn of the electrical era to the modern day. After consulting with a few forums, [dijt] got his hands on a schematic for his television set and began work on diagnosing what was wrong with it.
It turned out the original ballast tube in this set had long since given up the ghost. Luckily, this is a common problem in old TVs, and after consulting some forums [dijt] had a schematic to replace this ballast tube with some newer caps and resistors.
After constructing the circuit and testing it out, [dijt] mounted it in the old ballast tube to replicate the original look and feel of the 1949 television. Interestingly, this is the second time this TV had been restored; the 1960s-era caps and resistors told [djit] this TV had once went into a television repair shop. Let’s just hope [djit] remembered to glue the schematics to the inside of the chassis this time.
We’ve seen our share of commercially available HDTV antennas that work really poorly. For at least four years now we’ve gone without cable television, using a coat hanger antenna we made ourselves to record over-the-air broadcasts. But it’s a pretty ugly beast — we’re lucky enough to have an attic in which it can be hidden. If you’re in need of free television and don’t want an eyesore of a an antenna try building this foil and cardboard version. Even it if doesn’t work at all you’re only out about ten bucks.
The expensive part is the matching transformer which converts screw terminals to a coaxial cable connection so that it may be connected to your HDTV. You’ll need a few nuts and bolts, but we assume you can beg, borrow, or steal the tin foil, cardboard, and glue that round out the parts list. Glue, measure, cut, fold, fasten, finished! You’ll be watching horrible summer TV in no time!
If it doesn’t perform as expected just reuse that connector and try your luck with a fractal antenna.
[Michael Kohn] only accomplished about half of what he set out to, but we still think his TV channel switcher from a Chromebook turned out nicely. When starting the project he wanted to include a grid of listing so that he could choose a specific program, but decided that scraping the data was too much work for this go-round.
The Chromebook doesn’t include an IR transmitter so he built one using an MSP430 chip. He had previously built a little transmitter around an AVR chip and was surprised to find that the internal oscillator on that was quite a bit more accurate than on the MSP430. Timing is everything with the Manchester encoded signals used for IR remote controls so he used his oscilloscope to tune the DCO as accurately as possible.

Ah, CSI. What other television show could present digital forensics with such two-bit dialogue?
It’s time once again to put on your hacker hats – a red fedora, we guess – and tell us the worst hacker dialogue you’ve seen in movies or TV. We’ve seen a ton of shows and movies where writers and directors spend zero time doing any sort of research in whatever technology they’d like to show off in the story they’re trying to convey. Usually this results in lines like, “I’ll create a GUI interface using Visual Basic. See if I can track an IP address.” It’s technobabble at its best, and horribly misinformed at its worst.
We’re wondering what you, the readers of Hackaday, think are the worst examples of hacker lingo fails. Anything from, ‘Enhance!’ to the frightening real-life quote, “the Internet is not a big truck. It’s a series of tubes.”
We’ll compile your suggestions in a later post, but I’m betting something from Star Trek: Voyager will make the #1 technobabble/hacking lingo fails. There’s just too much in that show that isn’t internally consistent and doesn’t pay any heed to the laws of (fictional) physics. Warp 10, I’m looking at you. Of course there was the wonderful Habbo reference in last week’s Doctor Who, but I’m betting that was intentional as [Moffat] seems pretty up to speed on the tropes and memes of the Interwebs.
About a month ago, we asked you for your take on the worst hacking scenes ever shown on TV or film. The results made for good viewing, albeit with a surprising absence of Lawnmower Man. Now we want some dialogue to go with these horrendous hacking scenes. So, what say you, Hackaday? What are the worst hacking lingo fails you’ve seen or heard? Please be specific about what movie/TV show you’re referencing. Last time some good stuff probably slipped by because people just said a few words without context assuming we’d know exactly what they were referring to.
