“RUNNING LIGHTS”

A variety of light device (sdes), from the simplest to the most complex — widely used for the decoration of Christmas trees, holiday youth parties and even school discos. Therefore, the readers ‘ interest, the CDS continues unabated.
The proposed scheme is simple device “running lights”, published in the Italian magazine “m & e Pratica”. It is a multivibrator consisting of three interrelated stages. The opening of the transistors and the ignition is switched to their collector circuits of LEDs sequentially one after the other.
Concept device
 
In the manufacture of automatic switching facility to pick up the transistors with the largest possible gain current, and capacitors with minimal leakage.
 
From domestic elements to replace the most suitable transistors series КТ3102 and КТ342, LEDs of any brand.
