Daylight Bird or "Early Bird"
This is like the electronic bird circuit in Oscillator Section, with photo-electric control of the Transistor bias.
The operation of the CdS Cell is described in many other projects in this Section. We might call this circuit the daylight bird. We have made only slight circuit component value changes, and have rearranged the circuit Schematic.
Can you spot the changes and rearrange the circuits to look alike? Try to redraw the Schematic to look more like that of project Electronic Bird.
