Is anyone have LDD-350H drivers spare? Would be nice if I could have three.

Thanks,
Kevin

Fairly confident it's:

Blk - grnd
Red - +
Yellow - Tach
Blue - PWM

I've had a number of fans with a similar set up.

I have spare 700's and 1000's, that's it.


Scubasteve: Sweet, thanks!

Ya, I have the same things (700 & 1000).

Well again another very early morning thanks to the ever so diligent crows and robins :frusty:
Oh, well, might as well do something constructive. This is what my office now looks like, lol

And I got everything hooked up and it seems to be running, yaaaaaaay

The Arduino up and running the code:

And a shot of the panel box everything is mounted in temporarily:

I'm still waiting for my amphenol connectors that's why everything is only temporarily connected. I couldn't think of another way to test fire everything at once to make sure it all worked together. I also want to get this thing over my 77 gal and see if it has a positive effect on the coral and algae I just can't seem to kick. I do have MH bulbs that are 8 months old or so and at this point I'm not buying bulbs with this thing so close to operational.
I also have not finished my fan circuitry so right now the fans are not running on my heatsinks so that's next on the priority list.
I also have to fine tune the Arduino code because I have a couple channels used that the original code was using for sump lights and such that I'm not using. So I have to figure that out.

Anyway, that's an update for now. Hope ya'll enjoy. It appears to be getting lots of views but it's so quite in here :D

Got a question for all you wiring guru's. I want all my components housed by my arduino, I really don't want anything sitting on a heatsink. For ease of replacement/service, I also didn't want to link the LED's to each other. I want to be able to remove a fixture and not have it affect the other 2. So I have thus far gone to fairly great lengths in planning to accomplish that. BUT, turns out I'm 1 wire short to my fixtures, DU'OH!!!!!!
I have 8 strings of lights = 16 wires. My fan requires 3 wires for power and PWM and the heat sensor for the heatsinks require 3 wires. For a total of 22 needed wires. But the wire I have only has 21 :frusty:
Is there any way I can share a wire in the fan/sensor circuitry? Or am I going to have to run 1 single wire for my sensor or fan?

What kind of heat sensor are you using? I imagine that the sensor and the fan could share a common ground.

I'm was going to be using the DS18B20. It's got 3 legs on it 1 of which is a ground that goes to the Arduino's ground plane. I though maybe I could share that ground too but by Chris' schematic the fan grounds all go through either a 10K resistor or through a 2N3904 transistor and I wasn't sure if that would work...

Which actually brought me to another question about that 10K resistor. All I have here is a huge 3W10K resistor, will that still work in that fan circuit?

tagging along, this is really cool :pop2:

OOOOoooohhhh, look what I got today :D
