The Electronic Peasant’s LED Color Organ…

Ledcorg8Francisco writes – “Amazing electronic DIY projects and absolutely incredible craftmanship. The Peasant is dedicated to inexpensive, easy, and fun Do-It-Yourself electronics projects, particularly those which involve music production and reproduction as well as alternative energy. The color organ stars shown are built point to point, using a technique that I had never seen before. A MUST to check out if you’ve ever soldered anything!” Link.

  1. It looks like a good way to go if you *REALLY* like to solder… I think a much easier way to go is to use one of the LM391{4,5,6} bar graph driver ICs to drive each leg. They run about $5 each at your local surplus electronics store. You just feed an analog signal in and get 10 LED outputs.

    Looking on the Nat-Semi site(http://www.national.com/VCatalog/view.cgi/?command=toggleSort&attr1=Segments&attr2=0&a2=Segments%2F%2Fv%3A8&s0=PNumber%2F%2F1&a1=SubCategory%2F%2Fv%3A8&a0=Category%2F%2Fv%3A8&m1=SubCategory&t=0&m2=Bpn&m0=Category&as=0&render=1&domains=PNumber&q=200&i=PNumber&c1=e%3A0%2F%2FSubCategory%2F%2F%3Aeq%2F%2FDisplay+Drivers%3ALED+Drivers&c0=e%3A0%2F%2FCategory%2F%2F%3Aeq%2F%2FAnalog+-+Display+Circuits&tId=25) they also have the LP3943 and LP3944 which are I2C LED controllers with independent timers for each LED.
