I don’t have kessil myself, so I’m not sure what they need for an input. The module build from @Ranjib is for a kessil though.
I personally haven’t seen anyone do that yet. I have an orbit marine fixture but it’s gathering dust now. The controller that came with it quit. These lights have individually addressed leds. The feed to the lights is 3 channel and the current flows through. Gnd, power, signal? So does that mean the signal is digital to control the many channels? You might need to open up the lights and share pictures of the circuit to get help from people smarter than me.
Yeah! My controller quit as well, luckily it was still in warranty so Current USA replaced it. It just occurred to me that I have the old one. I pulled it apart and it looks like there's C1, C2, V, and GD connections on the PCB. I have the two light setup so I guess it's C1, C2 V, Gnd going to each light. I think those 78M06's may be MOSFET's. Maybe there are some "Smarter than me" people out there who know more.....
ok that makes sense. Do you know of a build thread that has used the 2 onboard pwm channels to control a single Kessil A160WE? The guide you quoted is awesome but it for 7 channels of lighting and I really only need 2 so the onboard channels are perfect and saves me the trouble of adding the PCA9685 chip. I'm hoping it simplifies the process significantly. Thanks for your help.I don’t have kessil myself, so I’m not sure what they need for an input. The module build from @Ranjib is for a kessil though.
“For one part of the build, we'll extend our previous reef-pi build to control Kessil lights (A360, A80 or A160), Kessil allows controlling the spectrum and intensity of the light using 10V pulse width modulation (PWM).”
So from his guide he is using 10v pwm signals. I would follow his guide from there.
Gpio are just on and off signals. They can be inputs or outputs. This would only be good for turning the lights on and off, but not for intensity. Pwm is for programming intensity changes. The pi has 2 3.3v pwm signals. You can get 16 more with a pca9685 chip. Then ranjib used an npn transistor to convert the 3.3v pwm to 10v pwm.

Yes you should be able to use the pi pwm to the npn transistors and not install the pca9685.
I googled 78m06 and it appears to be a voltage regulator. The rest is to electrical for me to understand. I would love for you to solve it though so I can copy.Yeah!

Reef pi displays through a web page. If you have an internet browser on MM and WiFi connection you should be able to display reef pi from your Lan.So I was moving apartments when I stumbled upon an old project I did several years ago called MagicMirror which essentially uses a screen behind a 1-way mirror/reflective plastic. After updating a module it broke so it kinda just sat in the corner but I am interested in restarting the project as a display for my reef-pi data. I have limited to no experience with the development side of using APIs but I can learn fairly quickly when it comes to programming. Before I get ahead of myself I was wondering if any of you brilliant developers/coders can answer a surface level question. Is this feasible for a newbie? Is the communication protocol fairly straight forward between reef-pi and MM? Here is the github link for the MM project. It has grown quite a bit over the last 3 years and definitely worth checking out if you have an unused monitor and some DIY ingenuity.

Thank you! My original thought was just to have a quick glance of tank temperatures, ph, ect that pops up as I approach the mirror. I think it would be much easier going the prometheus route and use an existing module iFrame is display the webpage. I appreciate the reply!
Yes. Is mm touch screen? If it is then displaying reef pi would be better so you can make changes.
It depends on the monitor you use and thickness of the plastic but I don't hear many positive things about making it touch enabled. I was just going to use it to display a snap shot of each tank (along with weather, commute time ect) and sprint to my laptop if something looked off.
After further investigation and downloading a magnifying glass app I managed to get a look at the MCU and it's a HOLTEK HT67F50. I Googled the data sheet it has a PWM output so I'm guessing that these lights may work with Reef-Pi. Now I have to figure out Voltage and current is required for each strip. They each have 60 LED's and require 36w. Next step is to meter the outputs on the programmer.
