Clouds, lighting, and thunder

[Rodasphoto]

I have a single 20" heat sink with blue, cool white, green, red, royal blue, and uv (violet) over my biocube 29 gallon. I was wondering if it would be possible to have a cloud effect, lightening, and thunder with some speakers be programmed?

I have the PWM dimming expansion and saw one in the section of the forum which would help me control the 5 channels I have working.

I think you are talking about this one:

Yes sir.

I currently have the cloud and lightning effect in my code, was wandering is there a way to change part of the code where the lightning is a lil more dramatic? Kind of like the Ai sol lights and controllers does?

Only if you have drivers that are capable of doing that.
Meanwell drivers have too slow response in my experience.

what driver (PWM) would you recommend Roberto?

I have only really used meanwell drivers and a DIY driver I build a long time ago. My DIY driver was capable of going down to 1% and I'm pretty sure would do very fast transitions, but it was a pain to cool it down.
I think those buck pucks should be able to do it. Ask Drew to test it. He's got some.
