In New Zealand
weíre in total lockdown and unfortunately my wife and I are both working in essential businesses so no sailing away for the month or however long this lockdown lasts. Sigh.
But, it does allow for time to really get into building the Pi and itís network for the boat, at home first with all the extra resources a dry land house affords.
First step is putting Open Plotter onto the Pi. No luck at all with the basic OP NOOBS install - no boot at first, then boot and install but black screen
after reboot. Bah humbug. So I installed the Raspbian NOOBS instead, which works just fine. Once everything updated and secured, I installed the OP advanced Debian settings. That was quite tedious as had to update and install each element of OP individually (via the graphical interface), but had it done and itís all working fine now. So far using mains AC power with the Pi offical power supply for the Pi and the AC to brick to 14.1V power cord for the 28Ē display monitor
Second step I've set up a 12V network here at home using an AC power transformer outputting 7.5A at 12V. Power for the Pi is sorted with a little Tecsun 25W 12V/5V converter. The 28Ē display monitor
(that is specíd for 14.1V 1.79A) seems to be happy with the 12.8V being output from the transformer after I cut the wire after the brick and attached them to the bus bar. So far so good. Iíve got a 5A fuse on the power supply and itís not getting blown. Sweet so far.
Hereís the little power system. The AC transformer is the big box at the top, then a small combined bus bar on the left, and the Tecsun for the Pi power. Iíve also wired a small 12V male plug
to test our Natureís Head
- Iíve made three plug and play spare fans so changing out a failed fan will be easy.
Donít worry, Iíll mount this on a board and lay things out nicely this weekend. And other than the wiring everything else is staying at home and wonít go to the boat.
Third, depending on the courier deliveries, will be adding the router and the mobile gateway (Iíve bought the Mailasail Red Box and 4G RoamFree Gateway from the UK - I like the sat phone
integration the Red Box offers and the Gateway offers global sims support). Once those arrive Iíll add them to the home system and set up the future local network for the boat and WiFi
Also waiting for the Yacht Devices Seatalk
NG to Ethernet gateway, which is coming from Russia
by post. That will have to wait for the boat install before I can test that and FINALLY have boat data on a network for OpenCPN and phones and tablets.
By that time hopefully the lockdown will be done and Iíll be able to mount all this at our nav station. Then weíll move the chart plotter mfd from the nav station to the cockpit
bulkhead (itíll be nice to have radar
and an outdoor visible and weatherproof screen out there). The large monitor will be used for planning and logging.
Hopefully this is interesting for others. If so, Iíll report the home network experience with the RedBox and Gateway in another post and the boat network integration and install after that.
