FM RADIO STATION TONE CIRCUIT PART 16
Here's a modification to make a tone selector switch for the FM radio station's electret microphone output. Changes for actual use require adjusting the 8.2K ohm resistor and the 1nF capacitor based on the voltage supply.
A tone selector switch is used as a high pass
filter to provide some tone adjustment. The 47nF setting reduces the low frequency and puts more of
the midrange into useful talk power.
For FM, a 1uF setting is used which
provides more full range audio suited to FM voice.
The
electret mic element inherently has a strong gain. The intensity of voice and the position of person speaking can be adjusted to provide the best gain without distortion. Experiment with distances and component values to find the best results.

BRAIN CORTEX INDEX PART 16
Over 50 installments to the development of a living immortal brain cortex in a jar
From concept to working prototype, join along as we create a science project so advanced in potable ramifications, that you'll be surprised beyond limit. The brain cortex in a jar is now evolving into many exciting projects and boundless ideas to explore many realms of science, the future, and immortality.
The brain cortex in a jar project objective is to develop a cortex machine brain, demonstrate
human-to-machine brain transfer, in particular to take some relatively
simple human characteristics and transfer portions to the machine brain,
whereby human traits could be given greater life longevity, leading
towards immortality.
