Looking good :-)and a little teaser.. ;)
Mine uses a L293DD for dosing pumps..
How did the integration go with the Wills lights, looks like it was pretty straight forward but I thought I read something about blowing some mosfets? Wasn't sure where it ended up build wise.Had to cobble together another box last night so I can control my new lights on my nem tank.
I get that blinking sometimes too, it happens when the signal oscillates above and below the treshold at which the light turns on. You can fix it by looking at what level reef-pi sets the light when that is happening and set the "minimum" value in the light settings to a point or two above that.
I will be honest I don’t know enough about that chip to consider it at all but heard that it gets really hot so that would put me off.
I'll take a look at that. Odd thing, it's just the blue channel in one fixture. If course the drivers in these are junk, but I have seen any similar that I think would work that wouldn't raise the cost a over what a better light would cost. Defeating the purpose of buying this one in the first place.
It is more flexible than the ULN2803 many of the reef-pi were built with.
Actually, the PH value using the API seem to be continently .07 less than the dashboard - is this a known bug?
Not that I’m aware of. I can check the code, if it’s due to calibration
In my testing The readings command does return the proper array including last values of both current and historical- but something seems off with the read only, I was thinking missing cal offset too. Thanks.
overcurrent? curious, are you using 2x of required capacity of that mosfet?
could be kickbacks? diods will help? I don't know.. I'm kinda guessing. I think you need some passives to protect the transistor
I have used the file driver to do something like that , for my model rail road setup.
How did you implement it?
I used a digital input using the INLETS Connector Pi17 pin - it under the ATO feature. I use it for a skimmer overflow sensor but this would work for a switch to trigger a MACRO I believe. You may need to hold it for 2 seconds or so but good to debounce anyway.
The check frequency on the sensor would have to be quite high, like 2-3 seconds to register the button press.
