USB-to-DMX-512 Interface + Sound2Light

sound2light

Hi,

I've found very good article on Circuit Cellar's September 2004 issue named "DMX-512 Control - Build a USB-to-DMX-512 Converter".
(Circuit schematics and programs can be found the authors web-site: https://www.kalbermatter.ch/index3.htm) Also I can supply pdf article on a demand.

Previously i've been trying to implement picmicro based transmitter for dmx controller but after showing this article i've decide to implement usb-to-dmx controller. But i've a problem with this article the author mentions "galvanic isolation" for protecting pc against over voltages. How can integrate such a protection to the existing circuitry?


After reading this magazine article i've searched some on google for pc-based lighting control softwares and saw very sophisticated one named eCue programmer (from www.ecue.tv). It has very powerful sound2light feature that will activated via hardware dongle. I want to implement such a complicated lighting control interface for my own use. My IDE choice will be LabWindows/CVI, i've some experience with it, but i need some techinal help for developing sound to light conversation...

Any help would be very appreciated,

Thanks in advance..

the dm168, the 8 channels pwm(100hz, 8bit) is so good for led.
