ATI power module addition

[gunzo]

scratch head for many moons before a friend helped out with the though process ..

I present my DAWN to DUSK simulation on the dimmable ATI Powermodule !!

Nothing much to see .. kekeke since everything is timed over a period of 1.5 hrs

Program goes like this

Dawn

Actinic Lights on dim at 0645hrs

Actinic brighten program starts 0700hrs

Actinic full bright at 830am and program starts dimming (crossover to the white lights period)

White light on dim at 900am

Actinics off at 930am and white light brighten program starts

End of Dawn transition to morning

Start Day

actinic lights on dim at 1030

actitic brighten program starts at 1045

white light full bright at 1100

both actinic and white full bright at 1215pm (noon)

actinic dim program starts 1pm

actinic dim at 230pm (afternoon)

End of noon

Start of afternoon to dusk

white light dim at 4pm

actinic dim at 430pm

actinic brighten program starts 5pm

white light off at 530pm

end of afternoon

Dusk transition

actinic dim at 7pm

actinic off at 930pm

End of Dusk

Finally !!! project complete liao .. countless sleepness nights and trips to sim lim to buy the parts coz burnt alot of diodes ..

You should use the Actinic to simulate moonlight too... coz I find your tank "black-out" a little too early at 9.30pm

[gunzo]

ok .. thank for the idea .. moonlight on from thursdays til saturday until 3am .. kekeke

Interesting project

better get a cover for your circuit bro.. haha later kanna water everything gone

[Sam999]

can u share the parts and drawing?

[gunzo]

simple diagram ..

parts you need ..

2 10v zener diode to cap peak voltage to 10v (that's the sense voltage from the ATI ballast)

4 1mOhm resistor variable (to adjust the bright and dim)

1 LM348 dual opamp (to output the power to drive the 10v)

2 1000 uF 16v capacitors

note the diagram only shows 1 dimmer .. you need 2 to drive the white lights too ..

the LM 348 allows you to drive 2 opamps ..

take note adjustments for dimming will require additional adjustments in bright since it affects the charge up state

BIG BEN .. this is just JIAM SI TONG until the the dimming module becomes available .. and its fun too while building it.. now just enjoy the setup ..

muhahaha yea i know. got the sense of achievement when its working. i used to do some sunple circuit in the past and one was a water sensor.. i placed it above the fish tank and somehow water got into the circuit and the whole damn thing fried !~ haha

series of shots taken at various times of the day ..

sad thing is can't see the effect and the house lightings also affect the tank

morning 930am (sorry dawn too early for weekends )

[gunzo]

1030am

[gunzo]

12 noon time (cloudy because I just changed water )

[gunzo]

3pm transition to after noon

[gunzo]

5pm transition to dusk

[gunzo]

8pm dusk dimming to night

[gunzo]

2 shots of night time one with living room lights on

[gunzo]

This is the same 9pm at night without lights on

Note that this is the dimmest that the lights will go .. kinda bright isn't it ?
