AVT791 A - sparkler, optical siren. PCB board

Description

The optical siren module flashes with strong pulses of light every few seconds. It is extremely attractive that the brightness of the diodes is not constant - the light intensity, very high at the beginning of the flash, decreases to zero in about a second. Such liquid stinging in the dark gives very interesting results. The described system was created for a specific purpose, however, due to the unusual light effect obtained, it can perform various functions. The flashlight can be used as a warning light, walkers or cyclists, fastening it to the backpack in order to minimize the risk of an accident during evening and night trips. This system, equipped with six super-bright LED diodes, ensures visibility on practically all sides.

The system is designed to supply 9V voltage from 6F22 batteries. You can also power it from single AA or AAA cells and replace the battery basket with the appropriate model. The use of individual cells will increase the energy efficiency of the package, and thus also the working time of the sparkler.
