Hi all:
I have ordered a batch of PCBs to build CAT4101 based LED drivers. The boards are the design explained in this thread on ReefCentral:

Some pics of the boards here:

Since the boards were so cheap, I have ordered 20 (min order was 10 for 12$, but with 5$ shipping, I figured I could order "a few" more). I will only need a couple, so if anyone is interested, I'll be happy to resell the bare boards, or populate them for you and split the cost of the parts.
These are drivers only, and will require a seperate power supply, but they are pretty efficient, AND dimmable.
Regards
Pat
