That's great! I'm still interested and I'm sure many others are. Can you post a video or something? As far as I know you are the first person to really come up with a solution like this. Awesome work man!
Just wondering if anyone is still interested in a FM tuner for android?
I've just built one using a ioio board and a sparkfun si4703 fm board. I've ported the ardurino code and have an early (very rough) prototype app which can tune, seek, control volume and read rds. It can connect via USB or bluetooth to any android device via my app. My user interface skills aren't that great so it's not that pretty at the mo, but hoping to find someone who can (or wants) to assist in that department.
Yeah I'm sure I can throw something together when I get home from work. Do you know anyone who can build decent UI's in Android?
Short video of the prototype as promised. I didn't mention on the video, but the volume control is controlling the output of the FM board, not the volume of the Android. The idea would be to have the audio out of the FM board connected directly to your amp and use an automated switcher to switch between the tablet and the FM tuner. Could easily keep the volume of the 2 devices in sync. ANyway that's for down the track thinking ahead of myself a bit.
+1 on the interested front. Keep the details coming!
Unit looks nice. No DAB/DAB+ for me in North America. But FM still works.
BTW, I found a device that can be used for audio selection and its made for a car (motorcycle) environment. It even has a priority input so whenever audio is detected on that input all other is silences:
