Schematic Circuit for Microphone Computer


Schematic Circuit for Microphone Computer


This circuit schematic was designed by Lazar Pancic from Yugoslavia. 

- Lazar has adapted the sound card to use a common electret microphone using this circuit. He has made a composite amplifier using two transistors.
- The BC413B operates in common emitter to give a slight boost to the mic signal. - This is followed by an emitter follower stage using the BC547C.
