Hey Neogenix, any update on your AIs yet?

As for me, a few changes in plans... One, I've decided to not go with the AIs... Why, you ask? Well, I've decided to test my patience and my sanity, er, rather, I've decided to go the DIY route and build my own LED setup.
Although, I'm going to do a bunch of DIY CAT4101 drivers powered by 2 PFCs, rather than all the Meanwells...
Bear in mind, this is looking down the narrow end (if something 4' wide can be considered narrow).
So, the plan being, with the drivers set up the way I'd like, and controlled either via an Apex or a DIY Arduino controller, I'll be able to selectively dim and brighten throughout the day to give the impression of the sun traveling across the sky throughout the day.

Now, my only decision is whether to build my stand myself or to have a steel stand welded up... Anyone have a good source for a welder in Austin or San Antonio?
