Sound Activated LED t-shirt - Part 2

So, in the previous post I described about the sound activated LED tshirt.

The tshirt is so awesome that I was not willing to open it up but then I love doing crazy things :)

So, I opened up the black box and the circuit was very cleverly made. The size was compact and components were soldered properly. I googled the components to find out more about the them and in doing so understood the working of the circuit.

Here is a video which explains the working -


The main IC which does the magic is KA2284 which controls the LED panel.

In the next post, I will try to decode how the LED panel is made and what are the connections in it.
