in past posts I have alluded to the idea of creating a portable 'demo rig' for the Aquariumatic; a fully functional setup that is easily portable and can be quickly set up to demonstrate to anyone who is interested in seeing the system work.
I have finally settled on an idea to build up such a case, and will be getting stardom on it next week hopefully.
The case itself is a small blue flight case with a workable width of around 16", and the plan is to mount a DIN rail in the lid of the case and one in the Base of the case. The rail in the lid will hold the Aquariumatic setup of one Control unit and also on Pi Hub unit; when the case is opened it will be easily displayed.
This rail will be powered by a DIN rail variable power supply.
the rail in the Base of the case will hold a switch, another variable power supply and have space to add further components.
I am also going to fit some additional Wemos D1 boards with arduino lcd Shields to act as dummy control units. These will be handy when demonstrating how the Pi Hub handles multiple tank data sources.
Eventually I would like to have power included in the display case, but until then I am happy to plug the case into mains to power it.
I am going to run mains to the switch and then from the switch to the two power supplies; this way I can control the whole unit from the one switch.
I'm open to any suggestions on how to assemble this little rig. Feel free to comment!!
