I plan on getting a apex lite or a reef keeper to control everything. If need be and budget doesn't allow, I have few arduinos laying around as well. I'm actually using one to control a relay box I made that controls CO2, airstone and the lights throughout the day.
I am open to other suggestion then the BML option. I am not committed yet.
Sent using these stoopid hooves..
I've played w/ using a Typhon (basic Adruno box) to do 10V dimming. It is not hard to convert the PWM to a variable 10V signal.. but it isn't what I would call elegant.. you need an opamp circuit and a >10v power tap.. There are plenty of diagrams for the circuit.. I WAS hoping to use the 10v PWM but the circuit is not designed as I would expect..
you can see my feeble attempt here:
I actually got the passive circuit desgned only to find the PWM output was too weak to run the Meanwell circuit.. I got the voltage I wanted (by doubling the V of the 5V PWM out) but cutting amps in half was the final barrier..
anyways the opamp circuit was simple.. Even simpler was changing drivers........
I increased Vout to 9.3 (I think) by changing diode types.. stll not enough amps fed to the Meanwell circuit..
Anyways the circuit that most use is like this.. IF you have a more elegant idea, let me know..
Thanks for sharing that. Regarding the 10v side is definitely different looking on the oscilloscope, (not a clean square wave), but oddly, it works just fine on the 10V PWM drivers, so we never really looked into it.
