AVT754 A

A simple gadget with super-bright LED diodes. The control system was made on the very popular C-MOS series 4000 - 40106. It contains six inverters with the Schmitt system. They were used to build two diode-control generators. Because the frequencies of both controllers differ, the system generates random sequences of alternate on / off switching of two LEDs.
The set includes two sets of tiles, elements (in the AVT754 B version) and four differently colored LEDs. This allows you to build two flickers and share your friends and acquaintances with them.

The device is especially recommended to all beginner electronics, lovers of lighting effects and those who are looking for a cheap, effective gift - a present

Selected parameters:

• light sources - differently colored, super-bright LED diodes
• the ability to adjust the operating frequency of each generator
• possibility of connecting four LEDs or two-color LEDs
• small dimensions, a small number of elements
• possibility of battery power (eg 9 V)
• power supply - 4.5 - 18 Vdc
• in the set, printed circuit boards (2 pieces) and documentation
  A version with a set of independent components is available
