We consider radios as audio units, however for people who find themselves visually impaired, it may be tough to inform which channel you’re listening to at any given time. [Sncarter] has a member of the family with imaginative and prescient impairment and constructed a radio to assist her. Sadly, it was tough to copy, so he determined to attempt once more. The result’s an FM radio that gives audible standing notifications about energy and frequency. Test it out within the video beneath.
This isn’t just a few hacked-up business radio, however a ground-up design that makes use of a TEA5767 with an ATMega328 for management. There’s an LCD for when another person would possibly use the radio and an audio amplifier. He constructed the prototype on a breadboard, however moved the completed product to a PCB.
It isn’t simply the electronics and the sound which can be assistive. The case has raised bosses to assist the person discover issues just like the swap and rotary encoder. The Arduino can communicate frequency bulletins, though the standard of the voice is one thing he needs to sort out within the subsequent revision.
These radios on a chip offer you many design choices. These similar concepts could be helpful for audiobook gamers, too.
