The eggs hatch incubator circuit is composed of the power supply circuit and temperature control circuit, and it is shown in Figure 4-6. The power supply circuit consists of the step-down capacitor Cl, discharge resistor R8, rectifier diode VD, filter capacitor C2 and zener diode VS. Temperature control circuit consists of the resistors Rl- R7, potentiometer RP, thermistor RT, transistor VT and thyristors Vl-V3. Rl-R8 select the 1/4W metal film resistors or carbon film resistors. RT uses the negative temperature coefficient thermistor. RP uses synthetic membrane potential, or precision multi-turn potentiometer.
