Sorry to be a pain, but a top down shot would be easier to figure out. Looks close though.

The purple arrow indicates the LM317 connected to the red wire. not the 470 ohm

Don't connect the 10K resistor to ground. That gets connected to the DIM+ wire. The 0.047uf cap should be connected to ground, which don't currently.

hi evil,
i know this can sound kind of dumb coming from me, but where is the ground on the board? i'm going to attempt the next dimming circuit next eek. i saw what i did wrong on my circuit. --------------------  LEDS AND LENSES GROUP BUY [size="5"][/size]ENDS JUNE 30TH closed******* Deep's 14bc with LED lighting 10 gal custom LED tank Jay's LED 12 gal AP by Deep |

Ok, I made this to aid in clarification
 Red lines are solder traces on the bottom of the board Black lines are component leads Blue lines are top side wires Gonna post this in the Meanwell thread. I'm going to make the circuit anyway and post pictures, but this should get people started. This post has been edited by evilc66: Nov 8 2009, 03:28 PM -------------------- |

That makes life a ton easier, thank you. I'm going to give the board another try.
Thanks. |

Are the 470 ohm resistor and a 1.5 k the same thing?

Well, the 1.5K is close enough to the 1K and 470 ohm series combination. The output voltage is a little lower with the 1.5K resistor, but it's just fine.
