Meanwhile , field testing is in full steam . Double checking dosing pump output , for me 100% speed, 10 second is 5 ml

Looks like your little helper is having a good time!

I understand. Jebao pp8 or such ( previously rw…) use 12v as power supply and have individual controller. I got no clue how the controller works though.

I think we need to get the code written to use pwm to control these. I believe they use 5v pwm and either a 12v or 24v power input. I'm trying to wrap my head around it with some other code and have a friend who is more knowledgeable working on it.

We have the equipment and everything already in our reef-Pi.

That would be cool.
I have one of the old RW 10 models that died and was playing around with the controller and the power supply is 24v and from what I can tell the pwm control is 5v.
I was thinking that it wouldn't be to hard to use the pwm built into the rpi and declare the jacks to the pumps as lights. Then you might be able to have some control over the on and of functions and some ramping speed without any programing involved.

Additional programing would be needed in reef-pi to replicate the functionality of the Jebao built in wave modes and feed function.

Designing the actual circuit to add it to the rpi is beyond my knowledge but maybe there is a way to hijack their board and have reef-pi control it?
This would also be cool if we could figure out a way to use the Jebao wireless OW series pumps and have the rpi control the with wireless but that might be a bit of a stretch since their wireless capability is just to link the pumps not to control them remotely from a main controller.

A simple slow ramp up and down using the same control as a lighting schedule would be cool. That way you could run 2 pumps, one on each side of the tank and have them ramp up and down opposite of each other throughout the day and then have them both ramp down to say 20 or 30 percent after lights out.

Just some thoughts for those with more knowledge about circuit construction and programing.

This sounds exactly like what I am working on doing to control my Current USA main pump. Been quite busy last couple weeks so haven't got back to it but plan on hijacking the output side of the speed pot with 0-5v from the pi.

I would be very interested to see what you come up with and maybe work out a way to transfer that to the Jebao boards.

Probably and that’s why I was asking your to create a dedicate dthresd so it’s easy to tack. I need the led circuit , and voltage measurement, jack configuration in ui and logs ,,,

Ok, well I will get to that today. I will do that as soon as i can as well as wire up the next test as well. I had to take a break for awhile. I read a little about motion as you were telling me to install earlier. Doesn’t look like I’m ready for all that at the moment so I will move I’ve got a new batch of blennies born last night that I need to start straining out some baby copepods for, and start souping up my rotifers. It will be the biggest hatch I’ve done as of yet in order to hopefully get some nice trade credit at a LFS for some more expensive broodstock.
I have several tanks, most are plumbed central circulation, as is typical broodstock setup. Not only that but I have to have separate tanks or tank systems for each stage, each with differences that need to be monitored. I’m using a whole heap of electrical outlets and looking at the reef pi the be able to automate all my tasks and at same time making it safer and more organized. It’s not a business, just a hobby but it’s the same amount of work. I’m still learning a lot. It’s a lot to keep up with. I’d like to see some sort of database down the road to store test results and set reminders as well. Wanted to share with you guys how cool it is to raise a few fish, just for a break from the tech talk. Some eye candy, lol.

Can anyone tell me how to start a reef pi build thread? I’m sure it’s really simple but not sure where to post. Is it in with tank builds?

Do they use a 5v signal or 10v, like reef octopus and tunze?

I assume you are asking either Diamond1 or me about the pump controls? On the Current USA Eflux controller I have, I measured the manual speed control knob (potentiometer) signals and it has a 0-5v output to the motor controller IC. I can't speak for the Jebao as I haven't measured that.

Don't know about the reef octopus or tunze but the jebao is the same as the current. 0-5v from the pot.

Hello Guys,

Having some issues getting the temperature sensor reading with my Pi Zero W. I had "something" working last night. I was reading three different "temperature" sensors with only one sensor plugged in, and none of them seemed accurate (off by over 12 degrees (f)). It also wasn't working out of the box, but I did something (don't remember what) and was finally able to see it.

So I reformatted the sdcard to try again and still not getting anything read. I have i2c & w1 gpio enabled through the raspi-config. Running the latest 2.0 rc3

My boot.txt looks like:

Code:

pi@reefpi:~ $ cat /boot/config.txt

# goes off screen, and negative if there is too much border
#overscan_left=16

# uncomment to force a console size. By default it will be display's size minus

(I tried specifying the gpio pin also, but it didn't make a difference).

But that won't show without doing a sudo modprobe w1-therm

Based on the /sys/bus/w1/devices it doesn't appear to be seeing the sensor.

Any thoughts or something stupid I am overlooking?

Edit: Oh yeah, I get this error:

When I was able to get rid of that error ( messing with the i2c settings in the config based with what I found online) that's when the "three" temp sensors appeared...

Can I ask, I have mars aqua leds 165w x4 all stripped down so modding them I'm not worried about, but if I want to pwm them properly how could I do it? The panels themselves contain 55 3w leds, I have 4 panels, so a total led count of 220 3w leds.

Now there split into 2 channels per panel, white and blue channel, blue channel uses 27 leds 3w each, white channel 28 leds 3w each, it uses 8 drivers that have manual dimming.

Now I'm thinking to replace how there powered by a better system than supplied so they can then be fully controlled by reef-pi via pwm and timers from the pi.

I've been researching some but it's very confusing on the power side of things, has anyone done anything like this? Or any advice about powering a strip of 108 blue 3w leds and pwm and a strip of 112 mixed white channel leds 3w.

Is it even possible to power and pwm so many leds in series?

If it does work it should work with any of jebaos even their gyre models. I'm a bit of a ways from testing though.
I'm still working on the temp probe and dosing pumps.

I've spent most of the day today trying to figure out how my second rpi just randomly changed resolution modes. Now that I got that fixed I can get back into the dosing pumps and getting those up and running.

Don’t reformat sd card or reinstall reef-pi if something is not working. They are rarely the culprit. Using raspy-config to turn on i2c and one wire. Which guide you are using ? I recommend using the new guides published in adafruit (particularly guide 1 and 3) .
Your wiring looks correct . Did you reboot after configuring everything ? Touch the probe after you hooked it up. And also measure the voltage on the three pins of your probe
