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

Hello . Raspberry pi difficult to buy in our country. And long delivery. But I can buy orange pi today. Is it possible to use this board instead of raspberry pi?

I'm willing to buy an orange pi and try it out. Can always use another board for playing with.. ;)

Since we have a question about macro's I know in order to call them from a timer they need to be marked reversible but I never fully understood why that was the case. Can anyone enlighten me as to why that is the only way that it will work?

Thanks

A timer, requires any an reef-pi entity (like ato, temperature, equipment etc) to act like a digital output (i.e. on/off) that can take two state, "On" and "Off" . Macros emulate this by running sequentially as their specification in "On" state, and in reverse order in "Off" state. Thus a reversible macro can simulate On/Off mechanism, making it controllable via timers.

I don't know if this makes sense or not, but its this trick in software that allowed me to integrate timers and macros.

I dont know actually. It might work as it is, without any modification, assuming the GPIO pin map is same and arm architecture is same. If that's not the case we might have to make some software changes either by building it specifically for orange pi (if the arch is different) or by allowing an alternate pin map(if gpio pins are different). Hard to say without trying out, but i think it should not be a lot of work to get it working, and if we are lucky, either zero or 3 builds will work as it is.

Thanks, yeah I will have to read it a few time and see if it sinks in, lol. It works when labeled as reversible and in this case its an easy macro but I can see where making a complex one more fun thinking in reverse order. :)

I'm in the same boat. I just burned out my raspberry pi and finding that there's no rpi to be found without price gouging. Does anyone know where I can pickup a rpi without needing to buy the 4 for $150? My old B+ cost me $35...

I went a couple weeks ago to a few sites that sell them and put myself in on the "notify me" deals, I was able to stock up.. picked up 2 Zero 2 W's and two Pi4 2gb all in one week..

I also have an ancient Raspberry PI clone called a Roseapple Pi. I fired it up this AM and am getting it updated so I can test Reef-PI on it. Should be interesting.. It runs a debian release and I believe it to be pin compatible with the RPi GPIO..
We shall see..

Did some updates on one of my controllers this week.

Old setup

after a lot of head scratching and burning myself with the soldering iron...

Much cleaner.. still can't get one of my temp sensors working though. I think I know why...

Hey guys,

I've been away for quite a while. But my 2 reef pi's continue to run without any hiccups. Perfecto!

I just updated one of them from v4.1 to v5.1. Upgrade went almost too easy.

I wanted to ask if there was someone I could copy to control a brushless motor. My perilistic pump is using a brushless motor. My wife complains about how noisy it is. I'm running it like a normal motor but I can't control it's speed like a normal motor. It's 100% or 0%. If I could slow it down it would be quieter.

If not no worries. I'll get her ear plugs.
And thanks again!!!

Do you have a link for the pump ? Can you use pwm or a hardware based speed controller to set the speed manually ?

It runs, but it chokes on the i2c, drivers and I get a 404 error on the UI.

I'm not sure how to initialize i2c on this board as it's 7 years out of production and the company that made is out of business..

I think this will help. First image is the motor. 2nd image is the adaptor board this connects to in the reef pi (Mike Lanes doser adaptor.

Currently the red and white wires are routed to pin 6 +12V on the 6P6C of the adaptor. The black wire is routed to pins 4 and 5 to give me twice the current capacity through the ULN2803A. Green and yellow are not connected. Pins 1-3 are used for a 2nd brushed motor. I no spare connectors in the box available. If I need to run new wires from the reef pi to the doser box then I need to cut into the cases.

I think what I should do is route the black wire to pin 4. Use pin 4 as on/off equipment. Leave the red wire on pin 6. Connect the white wire to pin 5. Use this as the doser pin and that would allow speed control through the PWM. i can leave the green and yellow wires unconnected.

Is this correct? I would lose the extra current capacity I currently have. The motor is rated to 12V 10w. So 0.8a.

Just got one of my lights working with one of the new Viparspectra boards from @theatrus had made up, looks like at least the one I am using is working fine. I did have some issues trying to get the pca9685 setup and working on 5.1. I reverted back to 4.3 but I need to go back and see if it was me or a bug, but had no luck getting pwm to work, most likely a mis configuration by me but need to circle back on that. It was a new setup so there were lots of possibilities but appears to be working now.

Took me a minute to realize the Kamoer motors have the brushless driver in them. I somehow assumed they didn't :)

This can also help. In theory, you can control just the blue wire with a PWM and leave the pump powered. Its likely to work like most fan BLDC drives and just stop on a zero volt PWM input.

There are many off the shelf Bldc driver that you can get from Amazon and then hook up with pi via pwm.

I found a second hand in the marketplace facebook pi4 4gb. I was very happy. Paid 80 dollars. And it turned out to be a scammer!!!!:eek::mad:
How to choose the most suitable among all - banana, lychee, orange ....

I’m running reef up 4.1 and getting this error when trying to edit my temp probes (I have three) under temperature tab:

something went wrong:

I’ve powered it down and rebooted. The temp graphs are working as far as I can tell.

The various Pi-formfactor devices do not use the same processor (the Broadcoms) - this has an Allwinner SoC. They're both ARMs, but the peripherals are not an exact match.

They do run Linux, but the specific IO pins and busses may not be in the same "spot" in Linux, or not supported right now by the Reef-Pi libraries. With some software work to remap some of the pins its likely to work just fine, but never tried one of these out of the box.

Morning folks, just thought I would post a question. I have been using some @Michael Lane goby hat boards for a couple years now and I am thinking about making some additional boards up for test rigs and spares (I always like having spares, lol). Just looking to see if anyone would be interested in having one as a test board etc, just trying to see if there is any interest. I have not worked out the cost yet but these are not intended to compete with the likes of robotank or leviathan but at least for me they are really useful and provide enough capability and are quick to do.

Here is the board on @Michael Lane tindie store - https://www.tindie.com/products/ranthalion/ml-reef-pi-hat-goby/#specs

Looks like if I get assy done on the boards it cost the same whether I do 5 boards or 20, just thought I would ask. :)
