idea

Aquarium controllers are very expensive and i do not want to build one using an arduino mega and breadboards. I am building a more powerful computer soon so i will be able to do PCB design. I am into electronics. I was thinking that i would design an open source aquarium controller with a wifi chip and an atmega2560 chip. The same chip that is on the arduino mega. I want to be able to use ammonia probes ph probes and other probes. Doers that sound like a good idea?
