DIY LED Driver

[M@!]

Has anyone here built a DIY LED driver? I was looking at this driver the analog adjustable driver and it seems like a fairly strait forward build.

That design wastes alot of energy, defeating the purpose of LED's. You should look up data sheets for LED drivers. Here are some of my favorites:

Maxim 16819/16820

National Semi LM3409, LM3406, LM3414

If you have multiple led channels you can use seperate drivers for each, or you can use one larger chip like the LM3464 to control 4 channels.

depends on what you are trying to power fixture-wise. As much as I like to build stuff I feel a DIY driver is not good time or money invested. There is zero doubt you can buy a Meanwell or the like for the same cost and zero effort. However, if you really really want to build one I highly recommend reading through this thread where you can get designs and sources for boards, driver, and other components. Not worth the time and effort IMO but cool if you are the ultimate tinkerer. Couple of these guys are quite the electronic guru's. http://www.reefcentral.com/forums/showthread.php?t=1759758
