DIY Arduino Due TEA5767 FM Radio

More mature hackers will bear in mind that a crystal established radio receiver was generally one particular of the first initiatives tried.  Moments have transformed, but there is nevertheless some thing magical about collecting invisible signals from the air and listening to the radio on a do-it-yourself receiver. [mircemk] has introduced the idea ideal up to day by developing an FM radio with an OLED display, managed with a rotary encoder.

The layout is relatively simple, based mostly as it is on one more venture that [mircemk] uncovered on a Chinese web site, but the construct appears extremely slick and would acquire satisfaction of place on any hacker’s workbench. An Arduino Thanks varieties the heart of the task, controlling a TEA5767 module, an SH1106 128×64 pixel OLED display and a rotary encoder. The audio sign is passed by means of an LM4811 headphone amplifier for personal listening, and a PAM8403 Class D audio amplifier for the developed-in loudspeaker. The enclosure is manufactured from PVC panels, and accented with colored adhesive tape for fashion.

It is much easier than ever ahead of to swiftly set alongside one another jobs like this by connecting pre-created modules and downloading code from the Net, but that does not suggest it is not a worthwhile way to enhance your expertise and make some handy gadgets like this a single. There are so a lot of sources offered to us these days and standing on the shoulders of giants has always been a wonderful way to see farther.

We have revealed some other radio tasks applying Arduinos and the TEA5767 IC in the previous, this sort of as this a person on a tidy customized PCB, and this a person constructed into an aged radio case.
