This article is to help sleep schematic presentation. The principle of combining text comprehension is a good suggestion. The principle is very simple but very practical and effective. Help sleep schematic based on electromagnetic radiation. Put it under the pillow, a built-in timer. In selecting a timing circuit selected via rotary switch SW1. Choose 15, 30 or 60 minutes operation. Select "Stop" or "alternate" mode is done via SW2. And SW2 is closed (Stop mode operation) the electromagnetic radiation stops after a preset time. And SW2 open (alternating mode operation) operation of the device preset time, then pause the same time: This cycle continues. Pillows and sleeping in the unit. Reset a cycle press P1 button. Figure: IC2C and IC2D generate two square waves of approximately 1.2 and 5 Hz, respectively. These waves form into 60μs pulse at the same frequency through C5 & C6 and mixed at Q1 base. This transistor is driven radiator coil with a scalar series of pulses 60μs length and 9 v amplitude. IC1, IC2A & IC2B forms part timers. C1 & R2 provides automatic reset of IC1 is turned on. Internal oscillator IC1 drives 14 stage ripple counter, about 15 minutes later, a higher output pin. Pin 3 IC2A down and stop IC2C & IC2D oscillation. If it is open SW2 (alternating mode operation), 15 minutes after the Pin 1 IC1 is lower, higher IC2A pin 3 and the  oscillator  is enabled again. If SW2 is closed (Stop mode operation), the first output pin 1 of IC1 is improved, the internal oscillator IC is disabled through D1. Therefore, the circuit is still dragging a reset pulse is applied to the pin 12 through the P1 or when the entire device off and then restart it. The same thing happened in SW1 is on position 30 or 60 minutes, significant changes in the length of time. IC2B D2 driver pilot operational leadership in the following three modes: Flash quickly and almost randomly when the radiator coil drive a little slower, often flashed on the radiator coil is suspended in alternating mode operation is automatically stopped when the circuit is closed (Stop mode operation). L1 get random winding enameled wire at 600 rpm 0.2 mm 6 mm diameter 40 mm long steel bolts. Ensure winding and insulating tape. The average current figure is about 7 Ma Ying-jeou, is reduced to less than four horses in the pause in the standby mode. Battery life can significantly increase the resistance of its associated lead omitted R5 D2. Use a plastic box to surround the circuit: metal cases can severely limit electromagnetic radiation.
