AVT2634 A

The presented layout is intended for people who have trouble hearing the alarm clock in the morning. The described adapter reacts to the sound of the alarm clock and after about ten seconds of ringing the alarm clock activates a much stronger sound that will not only wake up quite deaf. What is very important, the system does not require any interference in the interior of the alarm clock, and the service is extremely simple.

The printed circuit board and documentation are included.

A version with a set of independent components is available
