reef-pi :: An opensource reef tank controller based on Raspberry Pi.

[AshwinRavi]

I just published the first working draft for light controller (essentially a kessil controller) on reef-pi website: https://reef-pi.github.io/build-guides/lighting/

I could use some help with proof reading, my english is pretty bad, and I am fairly sure there are plenty of typo/spelling/grammartical errors. Other than that, if you think anything obvious is missing, do let me know,. i'll add them

I will let you know in a couple of hours

one thing that is confusing to many people is the bread board in the schematic if you show the connections with out the board and label some pin numbers that would be better

This is great.
With a cursory glance, there wasn't anything that stood out as to make it unreadable. If I get some time later today, I will do a full edit.

Do we need to do anything to buck the 12V from the supply down to 10V max?
For the auto lighting cycle, does they controller adjust values between the set points or just jump at each point? Just wondering since the PCA9685 is 12-bit.

Good suggestion. I'll add the pin out image that details raspberry pi pin to pca9685 connection,you think that will help ?

I don't think so , I have personally tested the official kessil controller and it generates more than 10 v output at peak. Sometime there can be voltage drop due to circuit components, so having a little more supply is helpful. Users can always opt for a 10v power adapter if they want.
Do you this k it will be helpful to add this information in the guide ?

If it isn't needed, I don't think it should be in the build guide as it may just confuse people. Maybe in FAQs though.

What about the pwm ramping?

 

[AshwinRavi]

Has anyone linked their heater and cooler to telemetry? I have my temperature updating just fine, just can't see the heater or cooler up there on my dashboard.

yes my thoughts exactly

What about the pwm ramping?

PWM ramping is smoothen out by reef-pi, it calculates the delta between 2 hour interval and applies it incrementally every minute. It's fairly gradual and can be observed via the telemetry dashboard

What version of reef-pi you are using ?

And can you share your log? Do you have adafruit.io feeds created for cooler and heater?

sorry for the glare, am using 0.4

reef-pi uses runs on Raspberry Remove the word (uses) SOUNDS BETTER

And the adafruit.io feed for heater/cooler has no values in it?

Thanks, fixing it right now.

Awesome, I'll add the pinout diagram in the docs.

maybe I added it wrong, I will check again.

I covered the temperature probe in .5 inch of silicon all around the metal. It hasn't rusted through this time, and it's stayed accurate for 1 month now. The last one rusted in about 5 days.

Will you tell everyone the exact probe you bought. That way we have it documented. Sorry, if you have already posted l it. Thanks

That's awesome. I was hoping this was the case.
I can't wait to get some lights to test this out. I have the PCA9685 board that I just connected, so I may have to rig up a 5mm led in the mean time.
