AVT EDU644 User manual

Brand: AVT

Model: EDU644

Type: User manual

AVT EDU644 is a unique educational soldering kit that allows you to build your own colorophone, a device that converts sound into a mesmerizing light show. With its integrated microphone, the colorophone reacts to the surrounding sounds, displaying a variety of colors and patterns in sync with the music or audio. It features adjustable sensitivity, allowing you to customize its response to different sound levels. Perfect for parties, audiophiles, and anyone who wants to explore the visual representation of sound.

However, we know that not everyone has as

sophisticated a sense of humour as we do, so we also

include the product description below if necessary.

It has not been known for a long time that the alarm

alerts, the painter paints and the resistor puts up

resistance. So, if one day someone were to ask you

what the Colorophon actually does, the answer is

childishly simple - the Colorophon colours :)

The colorophone catches the surrounding sounds and,

depending on their tone, frequency and intensity,

lights up in a quite different way for each sound. The

application of this smart device is much more

interesting than it might seem.

It is not only useful for partygoers, musicians and

audiophiles - there are many more options. From rave

parties (or indeed all parties), to signalling to children

that they are too loud, even to checking who is

snoring in what key. Referring to the above

description, virtually countless other possibilities for

the use of our Colorophone come to mind.

Of course, the most essential function of our EDU kit

is the opportunity to develop passion and soldering

skills.

Components received in the kit, may differ in appearance from those shown in the photograph. Despite this, they

have the same parameters, and their appearance will not affect their operation in the unit.

Figure 2 shows the layout of the components on the

PCB.

Solder the components sequentially onto the board,

starting with the smallest ones. Once the system has

been mounted, very carefully check correctness of

installation. Check that the components have not

been soldered in the wrong direction or in the wrong

places and that no soldering points have been short-

circuited during soldering. The sensitivity of the

Colorophone can be adjusted using potentiometer

PR1.
