I had close to 1.500 visitors on web page yesterday, after references were posted in news/blog sections : DIY Arduino FM Radio Shield « Adafruit Industries – Makers, hackers, artists, designers and engineers! and
DIY FM Radio Arduino shield | Freetronics
(thanks).
Regarding no posts here, there are at least two reasons:
- topic quite "specific";
- well explained, so no questions
As they say, incorrect statement, usually getting more attention /responses, than well formulated question.
Do you know anything about how this might be made to work on other frequencies ,433Mhz , 200Mhz or 20Mhz for instance?
IC TDA7088 works over 0.5 - 110 MHz, so it would be quite easy to cover this range. 200, 433 and up needs different chip, I'm sure there are many of similar functionality. Problem to get a BOB ( prototype boards ) which include IC with all peripheral hardware (R/L/C) below $2. May be channel selector from HD box, or an old VHS / TV receiver would be an option.
