HDMI to FM converter
thingiverse
HDMI to FM converter I need to hear audio from my amplifier using radio so I take avaible modules and create converter. Headphone amplifier and potentiometer is used because there was a huge disproportion of sound volume on amplifier and laptop. FM module has microphone working as default when no minijack is plugged in. Board has solder pads to disable this option (one picture show that). For interconnection between modules I use old headphones cable. used parts: HDMI to RCA converter https://www.aliexpress.com/item/32815095086.html?spm=a2g0s.9042311.0.0.27425c0fFEunVL Headphone amplifier: https://www.aliexpress.com/item/32873798605.html?spm=a2g0o.detail.1000016.1.332a115c4clxZE&isOrigTitle=true https://www.aliexpress.com/item/32775144587.html?spm=a2g0s.9042311.0.0.27425c0fFEunVL Potentiometer 2x10k logB http://www.dareltek.pl/pliki/pot.stereo.pdf
