| Ok...just for you Witfull.
jhnrb wanted to know of a cheap way to run fans in the canopy by using automation in fan speed depending on the temperature.As I have modded a computer for a friend which included one of these fan controllers.I'm trying to come up with a simple solution to apply the same fan controller in aquarium use.Now the only problem I see is using a power supply from a computer....it's bulky and produces alot of heat too.The electrical schematic above will provide the +5 and +12 volts needed for the operation of the fan controller unit only using a 12 volt DC in wall power supply.
My question was if I got it right or not. |
