So, here is a 3D rendering of the design I have drafted up:
As before it is a fully integrated engine and alternator controller, with the addition of some additional sensing ports to allow for monitoring of an optional water-maker (Monitoring for alarm, not active control / automation of the water-maker). It also includes the aforementioned CAN communications capability. It does feature a different CPU, the STM32F072, a bit lower cost – but also more programming pace, so the IDE will be a little different (A future project is to see about creating a board-type to support this new CPU under the Arduino IDE). I have the initial design completed, want to sit on it a while to do desk-reviews, but am looking to make up a prototype this fall, with perhaps a small professionally assembled run later this winter.
Will also be looking at refreshing the optional remote.
A major effort will be bring the firmware up to date. A major change I want to make is move from include file / compile options for configuring to using the ASCII command approach as on the Alternator Regulator.
OK, this is just kind of a heads up – letting anyone who stumbled across this blog know there is still life in the DC generator project! If any questions, and if you are perhaps interested in a controller this winter – drop me an Email and/or leave a comment below.
