If you are into vintage electronics or restoring antique radio equipment you may be very disappointed with the content offerings on AM broadcast radio these days. Fortunately there is a way to get around this: build your own short-range AM broadcast station and transmit curated content to your radios (and possibly your neighbors). There are several options for creating your own short-range AM broadcast station, and this gives you something fun to tune into with your vintage radio gear.
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!
