cheap mech timer + 12v transformer + co2 solenoid = co2 control?
I searched briefly for this and didn't find anything. What I'm wondering is if I got a cheap mechanical timer (the dial kind) and a 12 volt transformer like is used to charge cell phones etc. but 12v and connected that 12v transformer to the 12v leads on a co2 solenoid, would that work as a cheap co2 controller?
The solenoid just works w/ constant current right? So if the timer opens up for the period of time desired during the day, and the timer has a 12v transformer plugged into it that is wired to the solenoid, that should work as a timed relay right?
I don't want to get into the aquacontrollers just yet but wanted a cheap way to turn the pressurized co2 on and off. This rig would be very cheap and I can't see why it wouldn't work. Anyone try this?
