Older hackers will remember that a crystal established radio receiver was frequently a person of the 1st jobs attempted. Times have altered, but there is nevertheless something magical about gathering invisible indicators from the air and listening to the radio on a do-it-yourself receiver. [mircemk] has introduced the strategy proper up to day by creating an FM radio with an OLED screen, controlled with a rotary encoder.
The structure is reasonably easy, based as it is on a further challenge that [mircemk] found on a Chinese internet site, but the construct appears to be really slick and would take pride of position on any hacker’s workbench. An Arduino Owing sorts the heart of the project, controlling a TEA5767 module, an SH1106 128×64 pixel OLED display screen and a rotary encoder. The audio sign is handed as a result of an LM4811 headphone amplifier for personal listening, and a PAM8403 Class D audio amplifier for the developed-in loudspeaker. The enclosure is made from PVC panels, and accented with colored adhesive tape for design and style.
It is less complicated than ever before to swiftly place jointly initiatives like this by connecting pre-designed modules and downloading code from the Internet, but that doesn’t suggest it’s not a worthwhile way to enhance your techniques and make some valuable gadgets like this one particular. There are so numerous methods available to us these times and standing on the shoulders of giants has generally been a terrific way to see farther.
We’ve proven some other radio jobs utilizing Arduinos and the TEA5767 IC in the past, such as this 1 on a tidy tailor made PCB, and this 1 created into an old radio case.
