[LittleTern] — annoyed by repetitive advertisements — wanted the ability to mute their Satellite Box for the duration of every commercial break. Attempts to crack their Satellite Box’s IR protocol went nowhere, so they thought — why not simply mute the TV?

Briefly toying with the idea of a separate remote for the function, [LittleTern] discarded that option as quickly as one tends to lose an additional remote. Instead, they’re using the spare RGYB buttons on their Sony Bravia remote — cutting down on total remotes while still controlling the IR muting system. Each of the four coloured buttons normally don’t do much, so they’re set do different mute length timers — customized for the channel or time of day. The system that sends the code to the TV is an Arduino Pro Mini controlling an IR LED and receiver, with a status LED set to glow according to which button was pressed.

With the helpful documentation from [Ken Shirriff]’s research into IR remotes — yes, that [Ken Schirriff] — [LittleTern] had the needed codes for their TV in hand and a programmed and ready Arduino. They were able to 3D print a project box, attach it to their TV near its IR receiver, and power it off its USB! Bonus!

[LittleTern] has provided their code in their blog post. There’s a little timing tinkering that needs to be done to ensure it works smoothly with a given setup, but otherwise, gone are the days of fumbling for the remote as your program resumes!

Last night Massimo Banzi was Guest Judge on Intel  America’s Greatest Maker - episode 4 and had the difficult task of evaluating the teams and their projects competing in the Make or Break rounds for $100,000 and a spot in the million dollar finale.

Check some bits of the episode in this Meet and Greet video and in the Fast Forward of the episode!

An Arduino Uno appeared at The Tonight Show thanks to a project called Wildfire Warning System created by a 14 years old girl from California. Take a look at the video to discover how  you can detect fires  using a gas sensor and a temperature sensor.

And guess what? Jimmy Fallon knows what an Arduino is! Watch the video:

Video mixing chess games on tv in Norway using Ethernet Shield

When The Norwegian Broadcasting (NRK) planned the television broadcast of the Chess Olympiad 2014 in Tromsø, Norway, they encountered a challenge: how to mix video, graphics and the results of many ongoing chess games simultaneously, requiring 16 cameras for the games going on at the same time?

On their blog you can find a long and nice post about how they found the solution using Arduino Uno, Arduino Ethernet Shield and the library for Arduino to control such Atem switchers written by Kasper Skårhøj:

At first, the idea was to use a computer with a webcam for each of the 16 games, then mix video images, background animation and results in software on each of them.

Afterwards the finished mix of images would be streamed to separate channels in our web player, so that the online audience would be able to choose which game they wanted to follow. This solution would also provide our outside broadcasting van (OB van) with 16 finished video sources composed of video, graphics and results. This would make the complex job of mixing all video signals much easier.

After thorough thinking we came to the conclusion that for our web-audience, it would be better to skip the stream of individual games, and spend our resources on building websites that could present all games in the championship via HTML in real time. This would also give the audience the opportunity to scroll back and forth in the moves and recall all the previous games in the championship. We started working on it immediately, and you can find the result on our website nrk.no/sjakk.

Arduino cameo in the  theFollowing

 

The Following is an american TV Series which premiered last january and telling the story of

 former FBI agent Ryan Hardy (Kevin Bacon) and his attempts to recapture serial killer Joe Carroll following the latter’s escape from prison

On the 9th of April Season 1, chapter 12  aired and some of you noticed the unexpected!

An Arduino Uno spotted for the first time in a TV series at 17m 40s: Kevin Bacon jumps over an ArduinoUno-activated device … the red led blinking seems pretty dangerous!

But what kind of device is it exactly?

Automatic volume control puts the kibosh on loud TV commercials

automatic-tv-volume-control

If you’re having a hard time tuning out those loud commercials why not let your electronics project do it for you? This is an Arduino-based setup which adjusts television volume when it goes above a certain threshold. It uses a microphone, rather than a direct audio signal, so you can set it based on what is actually heard in the room.

The control scheme uses the IR LED and IR receiver seen on the breadboarded circuit above. The receiver lets you teach your volume up and down buttons from your remote control to the system. The one failing we see in the design is that the volume level is hard-coded, requiring you to flash new code to make adjustments (perhaps an enterprising reader could add a potentiometer for making easy adjustments?).

We can’t help but be reminded of the setup which reads the closed caption info to mute topics you’ve added to a blacklist.
