i do admire this set up mate for sure look like something off the death star, i prefer to keep it simple as poss but thats just me

must have took some doing getting it together, nice one mukka

Hardest bit would be calibrating the setup. And the cost atlas probes arnt cheap. I would do the nutrients by hand personally. Just so i would have atleast something to do.

This is mint, boggles my mind like, I just use a jug and pour the feed straight through.
All that air and feed to the roots costany though, if your on the ball and get things dialled in with a set up like this, your smashing it surely

I’m about 6 weeks out from having my own designed circuit boards in my hands as prototypes. Once beta tested out, I’m going to start selling the boards thus cutting the cost of this unit down to well under 400$ for everything I have in the videos above. Keep you all posted!

Thats good man best of luck!! Im still gonna be doing my own just for learning purposes. Not picked up my arduinos in a few months now. This threads giving me the itch.

Btw did you use a motor shield to controll the peristaltic pump ?

Open source version uses a 16 channel relay:
- 10 channels dedicated to peristaltic pumps
- 4 channels dedicated for high voltage power outlets
- 2 channels dedicated to “in” and “out” irrigation valves

Retail version will use 4 on board high voltage relays for outlets, rest are logic level MOSFETs for:
- 19 peristaltic pumps (15 for nutes and suplimemts, 4 dedicated for pH adjusters of both plants and reservoir)
- 3 irrigation valves (3rd is for new integrated valve in automating reservoir in two directions)

Each peristaltic pump is 12v/1a and OS allows you to configure a pumps rate, so you can fine tune them to precision. Great question!

Ahh i see so no pwm/HBridge? Im guessing your swiching relay on for say 10 sec and calculating water flow that way?

Wouldnt mind going though your open sorce code. Would give me some ideas and save me time.
