Led's Rítmicos Sequenciais.

Veja o link direto do You Tube: http://www.youtube.com/watch?feature=player_embedded&v=zs7PYNKClYY#!

Link da postagem: http://cassiobsk8.blogspot.com.br/2011/10/leds-ritmicos-vu-uma-ideia.html

Pra quem deseja um VU de leds tipo vai e vem , esse pode ser o ideal.

Fonte ajustável super filtrada.

Galera usar ponte de diodos de pelo menos 3A ou mais, onde se lê +25V é AC, se o trafo estiver C.T usar o terminal central na linha do negativo da fonte, no esquema está com 50 volts os capacitores eletrolíticos eu recomendo usar pelo menos 63V ou mais dependendo da configuração do trafo.
