LIGHT CONTROLS THE DOOR
Device for automatically switching-off the lights in the bathroom (dressing) room are designed to seamlessly allow the following situations:
1. In the served room is unoccupied, the door is closed or locked from the outside, the light is not lit.

3. Inside behind a locked door is a man and the light in this room must be turned on (lit lamp ЕL1).
DESIGN THE SOUNDS
Unusual sounds and sound effects using simple electronic consoles on-chip CMOS that is able to capture the imagination of readers.
The scheme is one of such boxes, presented in figure 1, was born in the process of various experiments with the popular CMOS chip К176ЛА7 (DD1).
This scheme implements a cascade of sound effects, especially from the animal world. Depending on the position of the engine variable resistor mounted on the circuit’s input, you can get almost real to the ear sounds: “croaking frogs”, “Nightingale trill”, “meowing cat”, “the bellowing bull”, and many others. Even the various human unintelligible combination of sounds like a drunken exclamations, and others.
COLOR SOUND
This attachment attaches to a regular television properties, a musical installation by changing the color of the image, respectively, the acoustic sound signal. When using the TV picture when speaking of the audience changes the color color.
Another use of the prefix is a color support of music programs with the aim of increasing their entertainment. Color television image will vary depending on the frequency and amplitude of the music signal. So, instead of blue and red appears green and green color changes to blue. Instead of crimson shade appear purple or brown. Patches of white telesurgery acquire pink tones. There are many different color combinations.
