FM radio

thingiverse

Hi! That's my first 3d design and first post here. This FM radio based on chinese FM radio module. I don't know its name, but you can find it as "87-108MHz DSP PLL LCD Display Stereo FM Radio Receiver Module" on ebay or aliexpress. Here for example: https://www.ebay.com/itm/272638277422 Besides this module you will need: * Two speakers (4cm diameter). I use 4Ohm 3W * Li-ion battery 18650 * 18650 battery holder https://www.ebay.com/itm/303998386062 * Li-ion battery charging module https://www.ebay.com/itm/203225413737 * Boost converter https://www.ebay.com/itm/284275062043 * Rocker switch 10x15 https://www.ebay.com/itm/283838687714 * Electrolytic capacitor. I use 16v 330uf * And maybe a small external antenna You can try using a piece of wire wrapped around a rod as an internal antenna. Like this:  But in my area FM receiving is not the best, so I use an external telescopic antenna. I have an article about this project. It is in russian, but maybe it will help someone: https://compacttool.ru/practic.php?view=18 <iframe width="560" height="315" src="https://www.youtube.com/embed/DSBTeV0rDnE" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
