I worked primarily from home for over a decade, and though I now have an office with a few employees, many of the challenges remain the same. Key among these is power, or lack thereof, and the havoc it can wreak. I recently set about upgrading from my old consumer UPS approach to a real always-on power solution for the home, and thought my blog readers would like to follow along!
If you’re a real hacker, you’re interested in all sorts of tech, from computers and the internet to radio to airplanes. The intersection of all of these interests is ADS-B, the protocol used by aircraft to share data like position and speed. Widespread availability of cheap software-defined radio (SDR) receivers and cheap computers like the Raspberry Pi makes it easy for anyone to join a global network sharing ADS-B data. Read on to learn how to build your own ADS-B receiver for under $100 and get involved!
ZeroTier is an incredibly useful tool to enable true access from anywhere to any networked resource. Although TrueNAS has removed ZeroTier support, the FreeBSD package is easy to install and seems to work fine! The only issue is that it doesn’t persist across reboots without some major risky work.
If you’re like me, you have a lot of different systems running in different places: at work, at home, in the lab, and in the cloud. And if you’re like me you’ve often struggled to connect and access these machines, especially when you’re on the road. At long last, I have a fully functional solution that lets me access everything from everywhere, securely and efficiently, whether on the open internet or behind NAT after NAT. The solution is ZeroTier!
My cloud of Intel NUC servers are powered by a generic slim 12 volt power supply from Chinese company Mean Well. This is a popular power supply with hobbyists and is widely available worldwide. I replaced the non-functional fans and 3D printed a cover for the terminals, and now two of my three “Rabbit” trays are up and running happily.
