building circuit——my first FM radio receiver

The building Blocks Circuit Radio consists of 18 electronic modules and a circuit manual. The purpose of this set of products is to let users easily get into the electrical world and build circuits gracefully.
Electronic module style is consistent, the interface is unified, the size is the same, can be any combination. These modules contain switches, resistors, leds, audions, operational amplifiers and other common electronic units, with these modules can be built a variety of circuits, the most typical is the radio. Circuit manual also provides a triode application circuit, logic gate circuit, self - locking circuit and other circuits. At the same time, users can also learn electrical knowledge, develop electrical logic, easy access to the electrical world.
