[dba-Tech] The wonders of the Raspberry PI

[Jim Lawrence]

I have heard good things about the Odroid but have not seen it in use...yet. What OS do you have on the device? 

If the Odroid is anything like the Raspberry it runs of 5 watts or less...and supports only devices using 5 watts or less. Most of the new screens have hdmi ports in them. I have been looking around for a small cheap one but if the Odroid is setup with a WiFi you can just run it remotely and you wouldn't have to worry about other accessories. 

The Raspberry has 4 USB ports, a hdmi port, a earphone port and a port for the NIC...same as Odroid.

I have heard some very impressive things about OpenCPN but have not seen Navionics. I might try and run up OpenCPN on one of my Ubuntu stations to see how it runs...it might even run on the Raspberry. ;-)

I have heard of some very small screens you can get for items like the PI and Odroid but if I remember the price seemed high.

I am using the Odroid-c1 (now an updated version is available).

Same price, but with a gig NIC and 4 usb ports.  Different video GPU 
however.  Quad 1 ghz cpu(s) and 1 gb of RAM.

Quite an awesome little machine.  I am trying to get it set up to be an 
OpenCPN system for my boat.  I have OpenCPN running on a Windows 10 
Laptop (ASUS) but as low powered as that is, it can't touch the low 
power requirements of an Odroid (or Pi).  OTOH I want a screen about the 
size of the laptop...

Nothing is ever simple.

I am trying to get a 15" or larger screen, mounted on a swing arm, below 
decks but visible from the cockpit.

I am currently using a Samsung Tab-s 10.5 which is awesome for the job, 
but doesn't like rain (of course) and is a bit small for the "below 
decks" bit, and it is running Navionics, not OpenCPN.  I love Navionics 
but it doesn't automatically follow the boat an so I have to use a 
finger to swipe the screen periodically to re-center the display over my 
current position.  Sigh.

Nothing is ever simple.

A complete OS with a substantial selection of applications and servers (full office suite, games (i.e. Mindcraft), SSH, Apache, multiple programming languages, full set of server tools etc etc...) The whole system takes only 3.9 GB so it will run fine on a 16GB SD (probably the smallest SD you can buy at $6.00).

I will install a copy of MC (Midnight Commander) as its foot print is tiny. Couldn't get Mindcraft to display properly, when accessing it remotely, as the game's graphic driver is not compatible, at least not by default.

USB 3 uses more wattage. I understand there is even a MondoDB module along with a MySQL and even a Postgress database option. One friend installed a copy of OpenWRT, on the product and is now using it as a very secure router.
