A few years ago I posted about a homebrew box I made containing a cell modem, a GPS receiver, and a couple of Raspberry Pi SBCs to handle Out-of-Band access to my gear at the datacenter where I only have one transit connection, and provide Stratum 1 NTP for my gear.
I’ve recently been working on cleaning up/modernizing some of my infrastructure here at home as well, and decided to build another unit, tweaked to the needs here at the house.
I don’t have redundant power feeds here at the house, so there’s only one power connection, and I have a number of other GPS-fed devices, so I put in one of my GPS antenna distribution amps, which makes it very easy to feed multiple receivers from the same antenna.
A little cheap OLED for displaying stats, and shove it all into a spare 1U box I had sitting around, and we’ve got a nice compact little setup.
