Ok here we go with the materials. I will have to give it in segments as I think of things.
Please be patient since I am really having to squeeze to find time for this. As I recall you were looking for a 10 foot area, so you would need to build 2 or them. I would suggest starting with one and see how that works for you.

By the way, in addition to the basic metal working tools, you will need a digital multimeter and a basic understanding of electricity and Ohms law. You will also need a temperature controlled soldering station, preferably digital.

1. Main Power Supply. I am using a commercial 24 volt 180 watt LED driver to power the entire frame. I can supply circuit design if you want to go with something else like a 12 volt supply. At the risk of being blackballed from this forum, I am going to pimp out some of my extra power supplies. I had to buy a large quantity of them to get a good price, so got a bunch of extras. $40 for the 120v units. I also got four 220 volt units, for $20 each and whatever shipping runs. I think I posted a picture of them earlier in this string.

2. Secondary power supply, some kind of 12 volt unit at least 2 amps, or you can use several smaller current units.Even a big wall wart will work. Not really critical since it will be used to power fans and illuminate some digital volt and amp panel meters which will be used for monitoring.

2. Heat sinks. I got them from a guy on Ebay. I buy a whole slab and he will cut them to size. Really good price. I have posted links several times on both strings. The slab will cost you a little over $100 bucks with shipping and you will have enough for two frames. The size is 4 1/8" measured across the fins and 4" in the direction of the fins.
You got 120 square inches of cooling surface or enough to cool 12 watts without any airflow, so we will have to get something going to get them cooled down. I am going to start engineering the cooling system towards the middle and end of the project. Worst case, I can strap a computer fan on the top of each module.

3. A crap load of K2 emitters (from Future Electronics). Let's say 60 percent red, 20 percent royal blues, 10 percent cool white, 10 percent warm white. But feel free to use whatever you think is going to work. You will be using between 8 or 11 of them per board. I will work up some different combos, but your guess is as good as mine.
Might as well pick up a handful of 5 watt 660nms also (Mouser) if you are feeling expansive and got a few bucks to blow.
Holler at me before you order the LEDs and I will make sure you are getting the right bins. I go with the highest ones available.

4. Artic Alumina or Artic Silver Adhesive.

List to be continued in next post.
