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

Ranjib I have a couple of questions, I know you get asked a bunch but I am scratching my head still trying to understand fets and I think I have a basic understanding confused concerning the frits diagram you had for the actinic https://learn.adafruit.com/assets/63978 the one on ada fruit had the in front of the gate and appears to be tied to ground. The pwm circuit connected to the resistor and then flowed to the gate pin (actually they showed two ways, one was a NPN transistor and the other was the fet and it did not have a resistor in the circuit). Here is the one that I am referring too - https://learn.adafruit.com/rgb-led-strips?view=all

Just trying to understand the actinic fritz diagram that is in that guide, thanks. Couple more questions, you talked about having a power switch earlier in thread and it's mentioned in the lighting guide, but wanting to know does it just kill power or does it activate a script which then shuts down reef-pi. I have been looking at some scripts to do a graceful shutdown but haven't played with it yet.

Other question is regarding event based controls, I would like to be able to turn off equipment based on something that happens to the system, here is an example: I have a hob filter that the motor is located in the HOB filter and not located in the tank, you fill the hob up to prime it so it can pull water into the filter. If/when you have a power outage, the water from the hob filter siphons back into the tank. Power is restored at some point and since there is no water in the HOB filter depending on how long it runs can burn the motor up. What I would like to be able to do is based on linux event logging etc I would like to create a routine (cron job) that looks for the event, e.g. uptime and based on those conditions take action, in this case I would want the outlet turn off to not burn up the motor. I haven't fully dived into the macro's so I apologize if this is already possible but thought I would ask, I can think of other event based things like leaking water etc that I might want to trigger and outlet. It may be possible to do it outside of reef-pi via api and a cron script just wanting to know what options are available.

Thanks :)

I assume you guys have seen this but in the desktop image this package is installed but not in the lite version, easy to do if needed but you can get the pinout via the CLI...


Pretty cool if you ask me...I have a 3 A+ so its not accurate for the layout but the pins are.

Here are the details if you want to add it:
sudo apt-get update
sudo apt-get install python3-gpiozero

To display the pinout just type "pinout" from the command line, handy way to see all the pins :)

@Ranjib is the alert from ATO functional?
I have received alerts from temp before (when I was on 1.3) and I have confirmed that everything is configured correctly with the test message, but I am not getting an alert when ATO runs for longer than the threshold I set.

I'll cross check. I cant recall any changes that would break this functionality.

Thats pretty cool :-p
after building so many thing with Raspberry Pi, I have now most of the pinout memorized :-)

I’m terrible at reading Fritzing diagrams but the Source of the N FET should be at Ground, and the Drain to whatever you’re controlling.

you have to configure alert settings under Configuration -> Telemetry, with your email credentials. The specifics are described in adafruit guide

I know it's small fry compared to the knowledge you guys have, but I just wanted to express my initial gratitude at such a great guide, the helpfulness of the users of this thread and the wider opensource community

From a total beginner/noob, this week I've managed to install and use a Linux distribution, run commands, install the required software, buy all the correct parts for the project and was able to deduce the +ve and -ve pins of a female barrel jack and reduce the voltage on a stepper!

Next week, I'll be attempting soldering for the first time to attach the HAT and start on the wiring required for my automated feeding doser.

:)

Thanks again!

Dude! That's a great start! And the reef pi community here is second to none!

You should start your own build thread. At minimum it will be easier to get answers to problems there. Things get lost in this thread.

Oh, believe me, when I build my reef pi, I will be doing my own build thread. It's highly recommended by @Ranjib and others. Plus, I believe you can get the fancy shmancy "Build Thread Contributor" badge on your profile. Although, I'm not certain on it.

Umm can someone tell me what a build thread means here?

If you want to do a reef-pi build, start a thread in the diy section. A build thread documents your progress and gives you a place to show your work and have questions answered.

thank you for the kind words. learning is fun :-)

Yes I do want to do that. I would really like to get some answered questions from those more educated in marine life than me. Plus I think it would be nice to document this from the ground up sounds fun and informative.

Go to the main "Forums" page.

Scroll down to "Do It Yourself DIY" and click on it.

Click on "Post New Thread" on upper right...

And BOOM! You're making your own build thread!

Thanks. Will do.

Build thread contributor badge is awarded to members who start their tank build thread in the aquarium journal section. I love them :-) . They are the signature threads in r2r and nanoreef . They embody a reefers personal journey , tanknshots etc. most of the learning are from these. I follow at least two dozens of those :-)

Ahhhh... I was not sure. Thanks for clearing that up!

Guys, I hooked up my two temperature probes and nothing, they're wired correctly, I feel the following command didn't get installed properly..

dtparam=i2c_arm=on dtparam=spi=on dtparam=audio=on enable_uart=1 dtoverlay=w1-gpi

Should I start again with the install or can I implement again from the console, any ideas @Ranjib ?

Then we need a Reef-pi badge instead ;)
