Production	The Netherlands, 2015.
Bands	FM.
Semi- conductors	TEA5767, zener 3V6.
Cabinet	None.
Power	DC 6V.

The Design

FM modules based on the TEA5767 IC can be bought for about one euro. Unfortunately, the IC must be digitally controlled so to build a receiver, an additional microprocessor is necessary. The idea behind this design is to disconnect the oscillator LC tank from the controlling circuitry. Instead, the oscillator is controlled by a potmeter.

Obtained	6/2015 from Own design.
Condition	5; abandoned project.
Disposed	Storage (inquire if interested to buy).

This Object

Execution of this idea is not so simple! The modules are really, really small. So at least you need microtools and microscopes to do the cutting and soldering; see Pieter here in his lab. After this, my prototype remained as silent as dead. Once I thought I vaguely heard a flard of noise (with the output connected to the Orion R636F), but this was not reproducable. So I abandoned the project in August 2015.
