A lot has happened since the last update! Its now time to start over with the HydroPWNics electrical and control system, the initial one while having a lot of good ideas and qualities ultimately was too complex and plagued with many mistakes in the hardware design. At first I was going to just redesign the separate modules, eliminating the design errors but then I decided to roll all their functionality into a single module. This new concept of a singular module has has been spun off as a separate project called SunLeaf which aims to be general purpose for all sensing applications. The new HydroPWNics electrical system will consist of a custom designed Beaglebone Cape housed in a single box with relays and AC outlets, eleiminating the control box and AC control box from the whole system. For sensing and monitoring SunLeaf Modules willbe flashed with an alternative firmware to auto join with the Beaglebone cape dubbed the HydroPWNics Cape.
The Contents of the cape is pretty simple. On board there will be two WiFi modules, one module will be for connecting the Beaglebone to the internet via the home WiFi network the other module will be for creating an adhoc network for connecting to SunLeaf modules. Also on board there will be power management circuitry to run the whole system off a battery if power is lost , a set of MOSFETs for relay control, and a RepRap discount display connector (hello incorporating existing open source tech ).
