At the end of the Light Mixer Panel article published in last year’s February issue we promised to complete the project with a compatible dimmer. Sure, the DMX Dimmer published in May 2002 could be used for the purpose, but the design is rather too extensive and complex to act as a simple dimmer. The circuit presented in this article is much simpler and cheaper!The 8-channel Light Mixer Panel published in February 2002 was well received by many readers interested in sound & light equipment, mainly because it was affordable and fairly easy to integrate in existing lighting systems. However, besides praise for the design we also received many requests for an associated dimmer circuit capable of accepting the standardised 0-10 V control signals supplied by the Mixer panel outputs. Although suitable dimmers with a 0-10 V control input are available commercially, the true DIY enthusiast will, of course, insist on building one himself, in line with his efforts a building the Light Mixer Panel.
