Looks like they can handle inrush. doesn't say how much

Separate relays for line and neutral for better isolation.

Looks like rtc class has only 1 alarm. So i can power on but need second alarm for off
will try TimeAlarms.h
.

Well Let's Hear From The Masses. What Yall Think
A) 1 Light Source From Start To Finish
B) Swap Out Light Sources As Long As It's Led

Ok The Poll Has Ended And The Masses Choose B. So You May Swap out Light Source As Long As You Inform The Competition And Its Replacement Is Also Led.

Mines not a tent or as small as that gorilla one. But I have an 18" X 20" X 30" veg space I made under my desk.

...on HLG240 datasheet...

INRUSH CURRENT (Typ.)
COLD START 75 A

MAX. No. of PSUs on 16A CIRCUIT BREAKER
2 units (circuit breaker of type B) /
4 units (circuit breaker of type C) at 230VAC

...

...seems to me ds3231 have two alarms...first alarm "accurate" to second... second alarm "accurate" to minutes... i dont remember where i read this info...sorry

pd... thanks Wilson... readed on github...

Alarm methods
The DS3232 and DS3231 have two alarms. Alarm1 can be set to seconds precision; Alarm2 can only be set to minutes precision.

https://github.com/JChristensen/DS3232RTC

...and i agree with Guod...
bye bye logic... i cant follow your arduino logic...
...or tell me what brand of wine i must use for this....

...on 24/0 lights are always on...

.. my inexpert pov.... on start... delay cascade way... start first one ... 1 or 2 second start second ...1 or 2 second start thrid... 1 or 2 second start four... etc...

,,on off we can try the similar delay cascade way... but on off...

...p.d... and seems to me actually there are more models on meanwell drivers on 0-10V Dimming mode... im refering to my first link info...

Can we get a recap of all the rules and basic information? When do we start germinating seeds etc.

I still haven't received my light, if I'm lucky I'll have it this friday.

 

[The Dawg]

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Looks like we have 4 rules
1)I'm Always Right
2)You Have To Grow In A 12x12x24
3)You Have To Use Some Type of Led(Can Be Swapped Out With Another Type Of Led) And Except The Driver Fan And Filter Everything Else Has To Be Inside The Tent
4)If You think Op Is Wrong Refer To Rule #1

My Mini tent lights Lights went off at 10pm. Then turned ON at midnight. HAL9000 said human error.
It was my fault. I had to || in code instead of &&
It hard to manage temperature inside this small tent. Will use a small heat mat.

10am lights ON, 10:26 Far red ON, 10:30pm OFF, 10:37pm Far red OFF
if (((hour()*60)+minute())>600 && ((hour()*60)+minute())<1350) {MorningAlarm();}
if (((hour()*60)+minute())>1346 && ((hour()*60)+minute())<1357) {FarRedAlarmON();}
if (((hour()*60)+minute())>1350) {EveningAlarm();}
if (((hour()*60)+minute())>1357) {FarRedAlarmOFF();}

For now code turns on 120mm ventilation fan every hour 4 minutes. ventilation turns on also on if temp in tent over 27C OR if junction box temp over 30C OR if humidity over 60%
inside tent 120mm fan on all times.

Ready for 4-20-2016.

 

[robincnn]

Need to increase humidity somehow
arduino a Log file entry every times any of these change
Humidity, Tent Temperature, Junction Box Temperature

Humidity: 34.00 % Temperature: 26.00 *C 78.80 *F
2016-4-13 21:32:34 Control Box Temperature=30

Humidity: 34.00 % Temperature: 26.00 *C 78.80 *F
2016-4-13 21:34:47 Control Box Temperature=31
Fan on. Tbox > 30
Fan on. Tbox > 30

Humidity: 33.00 % Temperature: 26.00 *C 78.80 *F
2016-4-13 21:36:8 Control Box Temperature=25

Humidity: 33.00 % Temperature: 26.00 *C 78.80 *F
2016-4-13 21:36:49 Control Box Temperature=24

Humidity: 33.00 % Temperature: 26.00 *C 78.80 *F
2016-4-13 21:38:1 Control Box Temperature=26

Humidity: 33.00 % Temperature: 26.00 *C 78.80 *F
2016-4-13 21:39:2 Control Box Temperature=28

I'll need it, many parts still aren't here yet.... SOON! Probably will have to retrofit the cooling partway through.

I've got a TGA sonic screwdriver clone ready to roll though, just setting roots. Ready for their master to hurry up and finish her new home.

 

[Psyphish]

My light arrived today, I could easily fit another one in the tent. Temperatures are basically the same inside and outside of the tent. I'm just worried the single COB doesn't put out enough light it's not very bright in the tent. I was going to put the driver outside the tent, but the freaking light has about 10cm of wire between the fixture and the driver?! You basically have to keep the driver next to the light if you don't have parts to extend the cable with.

ps. Could I use the plant in my picture as my competition entry? I know she's not a fresh clone, but I just feel like it would be perfect for the tent, I'd transplant her into a bigger container of course.

@guod
Arduino offers dimming . It can also act as timer with RTC module
Assuming 120V 16A breaker B type
To solve inrush current problem can i use Arduino10 A relays to turn on 4xHLG240 driver in 1 second intervals when its 'Light On' time.

I hear solid sate relays fail closed. so mechanical would be better.
I am not sure if these ebay and amazon once are mechanical or solid state

I have a relay board that I use along with a raspberry pi for my custom timer. I just had a relay fail closed right after I added some addtional lights in the cab. I was running about 100W and added roughly 200W more. So a rough figure of 300W of lights/drivers caused it to fail (I'm not an electronics expert but I figure the power draw would likely factor into inrush). The model of relay is : songle srd-05vdc-sl-c. From the document you linked, I think it's a 'form c' and would therefore be rated at 120VAC 3A inductive load and a max allowable power force of 240W.

will try TimeAlarms.h
.

separating line and neutral help with inrush? In my current config, I only used a relay for line. That same configuration just failed (see my previous post)

 

[robincnn]

Thanks. Looks like it will not work unless we get a bigger relay.
separating line and neutral will not help with inrush. I thought better isolation by disconnecting both line and neutral. Like a 2 pole switch

The fan was not working properly with PWM. Would start like a 2 stroke engine and make buzzing sound.
I removed the transistor and instead gave PWM signal to blue wire in my 4 pin 120mm fan.
same issues with fan. Read here that fan PWM needs a higher frequency and Audrino was giving 1kHz

I updated code to set PWM frequencies.
31.25 kHz for on Pin 3. could not get it in 21kHz-28kHz range
and fan has been working fine now

I'll be researching other relays - for now I'll reduce the load and move to a spare/unused relay to get back up and running.

If it fails that quickly for 300W then it might not last long with 100W either.

 

[caretak3r]

If it fails that quickly for 300W then it might not last long with 100W either.

ya, i know it's possible. I just ordered a pair of ssr 40a relays that will hopefully fix things. It makes me wonder what is inside of some of the cheap digital timers I have laying around. Could they be much better than the Songle? I may have to tear one down and see what's inside.

It's bumming me out a bit because I was already behind on my plans to test short day cycles. If it holds up for a week or so I can at least continue my 4/11 (although I'm not able to blast the plants with full power for my 4 hours of day as planned). oops, sorry, just realized I'm muddying your thread

 

[robincnn]

SSR 40A Where and how much
Feel free to muddle this thread with your arduino/raspberry pi circuit, photos and code
I have been thinking what would make a better timer/controller. arduino or raspberry
