This is what a particular Sprint PCS cell site in southwestern Miami-Dade County, Florida, looks like inside.
Shield your eyes, it’s horrible. No, actually, you will want to shield your eyes because the batteries were installed so badly that I felt the need to place some cut-up pieces of a plastic container in between the battery terminals and some aluminum-cased monitoring widgets that were sitting on top of them to avoid an electrical fire. (Upon testing the batteries I found then to be at about 10.1 volts DC. FAIL.)
And this kind of thing is why I trust ham radio for communications more than anything I pay a mystery team for “service” on. 🙂
The Arduino Nano is pretty cool but when using it for a project recently, I found that I pretty much had to pull it from its socket to use the USB serial interface for programming or a serial terminal. If the chip had received power before USB host connection was made, it would never appear to my system and programming was impossible. It was rather maddening.
