Hello, I have made a LED VU meter thingy using transistors following scheme similar to this:

Can anyone help me modify that design in order to get a dotted effect (one LED shining at a time) as shown in the second meter:
I ask for transistor cirquit because LM3916N is pretty rare where I live it turns out...
