An iTunes rating box for everyone

April 14, 2012 By Leave a Comment

If you’ve ever scoffed at the idea of opening up iTunes every four minutes to rate a song, [Steve] is the guy to talk to. He built a small hardware box with five illuminated buttons to rate the current song playing on iTunes.

This build comes after [Steve]’s earlier Arduino-based rating box that was functional, but didn’t have the level of polish he desired. To get to the current iteration, [Steve] designed a custom board around a PIC18F microcontroller programmed as a USB HID device. After a great deal of frustration soldering teeny SMD components, [Steve] had a functioning USB five-star iTunes rating box. With a custom acrylic case the build was finally completed.

We’re very impressed with the finished version of [Steve]’s TuneConsole, as he calls it. We can certainly imagine other people wanting a similar device. Whether that comes from releasing the schematics and boards or selling PCBs on Seeed Studio is something we’re eager to find out.

RFID playlists plus a QR code concept

March 15, 2012 By Leave a Comment

Here’s another audio playback hack that uses physical tokens to choose what you’re listening to. It uses Touchatag RFID hardware to control iTunes. The concept is very similar to the standalone Arduino jukebox we saw on Wednesday except this one interfaces with your computer and the tags select entire albums instead of just one song. A shell script processes the incoming tag ID from the reader, populates a playlist with all the tracks from the associated album, then executes an AppleScript to launch that playlist. Check out the short demo after the break.

But what really caught our eye is the QR-code reader concept which [Janis] hopes to implement at some point in the future. The computer side of things doesn’t need to be changed, but we love the challenge of putting together an FPGA-based camera to recognize and decode the QR image. Looks like a perfect use for that $10 camera module and it’s FPGA driver!

Overbuilding an iTunes rating system

February 25, 2012 By Leave a Comment

Even though iTunes and it’s song rating system has been around for over a decade now, [Steve] still hasn’t gotten around to assigning ratings to his vast library of MP3s. We can’t blame him – who wants to pull up iTunes every four minutes and assign a star rating to each song individually? To solve this interface problem, [Steve] set out to design a hardware song rating interface that fell down the rabbit hole into development hell.

The build started off simply enough – just an Arduino attached to a few buttons that sends data to a Cocoa app which rates the current song. Everything was working wonderfully until [Steve] restarted his mac and the COM ports went to pot. Wanting a ‘plug-and-play’ solution, he did away with the Arduino-based build and started designing a USB device that would display the current iTunes track and provide hardware buttons for rating the current song.

The current build is based around a very capable PIC 18F4550 micro. After looking up the USB HID protocol, [Steve] had some boards fabricated. He’s keeping us waiting on a final build report, but with the amount of work that went into this project, we’re sure it’ll be a winner.
