Re: Building ship computer Advice needed

..hard sound impressive but it's gonna be nothing unless you coat the motherboard and SSD disk... Corrosion run very fast on electrical component..
Whatever configuration you build or buy, coated it!!.. specially if you think navigate and put a lot of nav chart and concentrate there all instrumentation...

Re: Building ship computer Advice needed

I have a number of computers onboard that relate to research. Coat your ports (USB, video ports etc) with silicon grease. Otherwise over time, the salt air causes these ports to oxidize. Do not use any sort of petroleum based coating, which can dry and harden over time, which can cause oxidation and poor or no electrical contact.

I had to send a Furuno black box back to them to have a motherboard replaced because of a rusted USB port...it was very expensive.

all circuits will be coated in platinum cure silicone
heat sinking will be to finned case
all my instruments will have some redundancy built in
and i always carry paper to use in the event of e charting failures

I use coconut oil, is that bad? I don't know where to get silicon grease.

I just scrape the rust off with a knife. Only the outer part is tin plated steel, the contacts should still be gold.

Re: Building ship computer Advice needed

I use vasoline on all my connectors. Never had a problem in 40 years.

I read a lot about on-board computer systems. But no information of what is a good led marine monitor with a daylicht screen, 12 volt and a dvi hdmi connector.

Re: Building ship computer Advice needed

I had a computer built for me. Cost $1,000 all in and it gives me all the ports and USB connections I need.

See Bob at Marine PC's & WiFi by IslandTime PC

Also with 12 volt power supply and then I found two Samsung LCD monitors that are also 12 volt.

The price is one issue, a home-made system is a lot less expensive.

Another important issue is not to be tied to a manufacturer's proprietary stuff. Building your own ploter with ocpn and your own charts gives you freedom, and maintainability.

In any case, we use a trasportation mean that is very obsolete, if you want the best technology can offer, fly to your destination.

Eating fruit is obsolete because we can eat fruit bars.
