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.


Contact lenses small made from transparent materials lenses, worn directly on the eye for vision correction (i.e., to improve visual acuity).
Normalizekey camera capable of capturing images with a resolution of 1280 x 1024 pixels and record video (720 x 480, 30 frames per second), the adepts from the land of the rising sun fit in the case the size of a normal flash drive.
A certain enthusiast by the name of Simon Whitlock set out to build not just powerful, but very powerful motorcycle. You can go simple way – to attach to a motorcycle frame any brutal engine of a large volume, such as from a Viper or Corvette, but then the design would be too bulky and large, which is undesirable.
An-70 medium — range cargo (operational-tactical military transport) aircraft of the new generation of short take-off and landing. Antonov an-70 intended to replace the obsolete An-12. Performed on the aerodynamic configuration vintoventilyatorny four-engine turboprop high-wing monoplane with single-finned tail and tail cargo hatch.
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.
