Beaglebone Black picture Screen shot

As stated on the home page, I wanted to see if one of my spare Beaglebone Black single-board computers could cut it as an always-on server since it dissipated only about 5 W, and so in February 2014 I created this website, and indeed it worked very well. It was a bit limited as a high speed file server due to the 100 Mbps ethernet port. The left-hand picture shows “illuminated.duckdns.org” in action with the Beaglebone, while the right picture shows some of the system information.

ODROID-C2 picture

But eventually I decided to upgrade, so in June 2016 I switched to an ODROID-C2. It had a significantly faster 64-bit CPU, much more memory, and a gigabit ethernet port. The only limit it had as a web server (in principle) is my cable modem connection to the Internet.

ODROID-N2 picture

But the “principle” seems to not be the end of the story. I couldn't resist the ODROID-N2 when it came out in 2019, and it shows somewhat faster network upload speeds than the C2. So at the end of July 2019, I switched the site to the N2, and that's where we are now.

All three devices

Just for fun, here is a picture of all three side-by-side. Left-to-right are the Beaglebone Black, ODROID-C2, and ODROID-N2.

The URLs “illuminated.duckdns.org” and “flatcoats.duckdns.org” are provided by DuckDNS. The SSL security certificates are provided by Let's Encrypt. The site webserver is nginx which is running on an ARM port of openSUSE Leap. (See this forum thread.)
