The sinking of the Estonia

A very harrowing tale.  It brings memories of the Titanic movie to mind.

The story of the Estonia

New post!

I am still here, just taking a brief break.  Winter is coming up, so I'll have more time to research and post about nerdy or other interesting stuff.  Meanwhile have some very cool blues.

Nuclear Instrumentation and Reactor Safety

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

Fixing stuff

One of the members of our church purchased a small "All-in-one" stereo system at the annual church garage sale.

Cute Makita Drill

We were going through my late father-in-law's stuff recently, and came across a cordless Makita drill.

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.

Russian missile test and radiation spike - 3rd Update

There have been a few news articles lately about a missile testing accident in northern Russia.  This accident allegedly caused a brief spike in radiation levels in the nearby city of Severodvinsk.

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?".

Zenith Console, Model 10-S-464

I really should stop doing this.
