I would very much like to see the diy also, however, the controller i purchased will be running some equipment as a timmer, and some equipemnt based on canopy temperature, and will controll all lighting, fans, and automatically adjust the length of the lighting day throughout the year once needed data is programed in. will also turn off lights as programed based on canopy temperature and keep them off in order of program for amount of time designated. anyway. i want to do multible tasking with this controller and found the aqua jr. gave me the capability to do that. now the controller is only 3" x 5" x 1". not very big and does not take up space to speak of. will post pics when all is connected. since i still need to decide on how to control the equipment in the equipement shed, I would very much like to see the diy as i will have a lot more going on there and have need to activate based on time, temp, and humidity. thanks to all for the comments and feedback.
