Power consumption is not included in this price.

Audience security... I forgot that one. Okay, DMX is the way to go. Renting is ok for me. But say that I simply use the lighting installation of the club I play in : would I just bring my laptop and DMX controller ? If the club's lighting installation isn't "DMX compatible", would a set of dimmers do the trick ? Can I expect to find such "DMX compatible" lighting installations (like dimmers I just plug my controller into) in most of clubs/discos/concert halls ? (I suppose that I should just ask places I know...) I'm very new to lighting, sorry if some of these are silly questions. > On the other hand, if you really want to spent a lot of time with > soldering, hacking and (kernel) programming, you might use the following > approach for the electronics (no, I don't have schematics).

Amazing. But well, these guys are real hackers I can't compare with. As I said DIY is ok for me, but to a certain extent only. This is too complex, and would take too long to build, not to mention audience security. Thanks a lot ! -- og
