I am in the process of changing boats, moving from a larger lift keel yacht to a trailer sailer. The new boat is bare, which has given me the opportunity to start the electronics from scratch.
I have finally finished my first build of the my Openplotter computer, I say first build as I would like to build a custom PCB for the interfaces to the Pi, but I wanted to get everything together in one box and tested before I finalise my PCB design.
The case I am using is one by Western digital, they made a few add ons for Raspberry Pi for about a year, and I brought up a few bits when they finished their pi range.
I decided that I would fix on a form factor and work to make everything fit within it, so I removed the case from the DVB stick and wired it into a usb cable to save space.
The board in the top left is an opensource seatalk to NMEA board, running a PIC processor.
The two OLED displays were kicking around and I thought would add a nice feature of having some status info onboard, there is also a nice feature of the case that allows them to be seen through the cover:
The displays are driven from Node-red, more work on this side of things is due, so I can use the reset button to change what they show, and also reboot the Pi.
I am waiting on a number of bits from China to enable me to carry on with the next stage of the build, this includes custom PCBs for the autohelm remote and for relay control and buttons.
display wise, I have a couple of options, one is the 7" raspberry pi display, which I will mount separately to the case. I also have an old laptop display which is obviously a bit bigger!
I will update this thread as I build more of the components.
