The black box contains electronics so I can control timings with software. Here are the values I'm starting with:
// THESE CONSTANTS SET THE TIMING AND FUNCTIONALITY *******************************
/* 10 seconds is 10000
* 1 minute is 60000
* 5 minutes is 300000
* 10 minutes is 600000
* 1 hour is 3,600,000
* 6 hours is 21,600,000
* 18 hours is 64,800,000
*/
const int FogInterval = 30000; // number of millisecs between fog cycles
const int ResFanInterval = 10000; // number of millisecs between Res Fan cycles
const int PowerHeadInterval = 10000; // number of millisecs between PowerHead cycles
const int LightInterval = 10000;
const int TentFanInterval = 60000;
const int FogDuration = 50000;
const int ResFanDuration = 3000;
const int PowerHeadDuration = 10000;
const int LightDuration = 10000;
const int TentFanDuration = 60000;
I'm going to open source all this stuff, if we have any hackers or makers out there, I'll share the designs and the software for this project, just ask.
A normal timer does not give me the amount of control I want to see what the set points SHOULD be.
I'm also using Aqua's design on this to inject O2 in the res. After steady state is achieved, there should be 90% O2 in the res atmosphere / root zone.
Lots more, I'll post it up as I have it.
