Dimmable Lunar Hub

[lnevo]

The relay expansion dimming ports are non functional. You'll need to use the dimming module.

Thanks Lee .. guess its time to break out the soldering iron to make neat cable ends ..

Can these be run from the Power Control Expansion or does it pull to much amps?

[rimai]

You should be fine.

[Sacohen]

I noticed that the PS that came with mine was 2A and I know the Power Control Expansion has a limit of 500ma.

[rimai]

Oversized PS for when you want to connect a lot of moonlights to the module.
As long as you don't use too many moonlights connected to the hub, you are fine. I'd not go past 4 moonlights using the power control module.

[Sacohen]

OK. Thanks.

Guys,

Is there any additional code for the moonhub needed over this?

ReefAngel.PWM.SetChannel( 5, MoonPhase() );

My lights are constantly on .. They never seem to change strength? Would it make any difference if I'm using the first generation dimming module?

[Sacohen]

Roberto had posted some code for that, but I can't remember where I saw it.
I'm going to need it too.

[rimai]

It changes at midnight to follow the moon phase of the day.
If you want to turn them off at specific times, you need to tell the controller to turn it off.

Code: Select all

if ( hour()>=8 && hour()<20 )
ReefAngel.PWM.SetChannel( 5, 0 );
else
ReefAngel.PWM.SetChannel( 5, MoonPhase() );

Got my lights hooked up and at 58% (today's moon phase) they are still brighter then my regular moonlights.
Also 2 lights work fine off of the 12 v Power Control Expansion.

[rimai]

Yeah, those are pretty bright
It's too bright for my taste too.
You simply need to divide the value by a factor.
Something like this:

Code: Select all

ReefAngel.PWM.SetChannel( 5, MoonPhase()/2 );

This will cut down the intensity by 2. Personally, I divide by a factor of 10.

[Sacohen]

10 wow that's a lot.

Yeah... I just like a very dim and faint light.

[Sacohen]

I actually like the way it looks. These light are more even then the other LED moonlights I had.

Before the light just kind of high lighted the tops of the rock work.

[Sacohen]

Can I use the PWN slope woth the MoonPhase?

Would the code be like this...

if ( hour()>=12 && hour()<22 )
ReefAngel.PWM.SetChannel( 5, 0 );
else
ReefAngel.PWM.SetChannel( 5, PWMSlope(21,0,11,0,0,100,60,0) MoonPhase() );

[rimai]

Yes, but you are missing the *, which means times and also the /100

Code: Select all

if ( hour()>=12 && hour()<22 )
 ReefAngel.PWM.SetChannel( 5, 0 );
 else
 ReefAngel.PWM.SetChannel( 5, PWMSlope(21,0,11,0,0,100,60,0) * MoonPhase() / 100);

[rimai]

Or you could also do this, which is basically the same thing:L

Code: Select all

if ( hour()>=12 && hour()<22 )
 ReefAngel.PWM.SetChannel( 5, 0 );
 else
 ReefAngel.PWM.SetChannel( 5, PWMSlope(21,0,11,0,0,MoonPhase() ,60,0) );

[Sacohen]

Thanks Roberto.

Just got my new lunar modules. They are much better than the old ones. Not as bright but more more spread and a cooler blue.
