Description

Indicator Light  "ON AIR"  in PCB for Audio Studios
 

 

In all radio studios there is an "On Air" indicator at the entrance (most of the time).
When the light is on it just warns us to be quiet ... because the microphone will
"pick up" ... our sound.
 
The construction is easy, it just needs 67 LEDs ... and of course 67 resistors 1/4W
(one for each LED, uniform lighting). The operating voltage can be 5, 9, 12VDC
and depends on what you have available. PCB are 165 x 50 mm !!!.
 
Of course the resistors must be adjusted according to the voltage you will put on the
PCB. Example find in link. You can find all files for construct this project ... in my Link.
