Once again, it's been quite a while since I did a nerdy nuke post... Time to remedy that.

A couple of little hikes
My daughter and I went on a couple of hikes recently, and saw some things we hadn't seen before. I'm sharing it here because it's cool and interesting.

Nuclear-Powered Rocket Engines
In the previous post, I conjectured that a nuclear-powered rocket motor test had gone sideways near the city of Severodvinsk in Russia. It turned out that I was correct in most of the guesswork.

Why do some LED bulbs create radio frequency noise?
A while back, I tried to replace the incandescent bulbs in our garage door openers with LED bulbs.
I started my next shift and promptly forgot that I'd switched them out - however, the garage doors stopped working with the remote. My wife was the one who put 2+2 together, and realized that this loss of function was due to my replacing the bulbs. I switched back to the incandescent bulbs, and the problem vanished.
I then did a little research and learned that this is a pretty common complaint with LED bulbs and garage door remotes. I've since managed a work-around to get LED lighting, but the problem got me thinking - and back to the title of this post: "Why do LED bulbs create radio frequency noise?".
