The cordless microphone receiver unit below is constructed on a 0.l inch matrix stripboard having 15 copper strips by 26 holes, as shown in the illustration diagram.
After previous post about how to make a cordless microphone transmitter, it is our turn to post for section about how to make its receiver. The circuit diagram of the cordless microphone receiver is shown in the following illustration.
Figure below shows the 0.1 inch matrix stripboard layout for the cordless microphone transmitter, and this is based on a board having 14 copper strips by 23 holes.
It is more convenient and less cumbersome to have a microphone which couples its signal to the transmitter in a way which does not require any connecting cable. One way of achieving this, and probably the most simple way, is to use an infra-red link.
