I guess the question I have is could you provide links for the parts or at least to the dealer. I am very interested in making some led strips my self. Thanks. Looks great.

That 317 regulator must get pretty hot.

Looks very nice. Think you could make up a smaller version for a dash light?

retail price per piece about 6$ per module complete


for lm 317 regulator , it s not very warm because he regulate from 12v --)9.6 volt
