Experiments are we going to do this time is to make electronic circuits that are designed to wake people who always sleep soundly, making it difficult to wake even if something happens around it. In the circuit will occur oscilasi process conducted by the transistor TR1 to produce frequencies that can interfere with hearing people who were sleeping. The frequency of exit through its output in the form of a voice that said tests-tests. Sound can tickle the ears of those nerves that had been sleeping soundly. When the switch is turned on, it began to sound tests and you can adjust the sound to the point of maximum by using the potentiometer R2, other means can also be arranged by replacing the capacitors C1-dressing. If you want a volume control equipment to be installed, you can install the 5K potentiometer connection between TR1-C1-R1 and SP1-L1
