A solid-state recorder
This device is an outstanding choice for a talking doorbell or any other application in which a short text of your own choice must be repeated. The length of the message is naturally limited, but it can be increased by coupling several modules in series.This type of record/playback unit always has a special kind of fascination. After all, it’s not that long ago that the recording and playback of speech or music without the aid of moving parts was only possible in science fiction stories. However, in the past few years these ‘solid-state’ recorders have become familiar objects. Since there are innumerable possible applications for such a device, both commercially and in the household, Velleman have include one in their catalogue of construction kits, and at a reasonable price.
