Wiring a Lionel 1033 transformer

Wiring a Lionel 1033 transformer

When it comes to wiring a Lionel 1033 transformer or its brothers, the Lionel 1044 and 4090, there’s more to consider than just which posts to use. The size of the wires also matters. If you derail a train 4 amps of power can run through the wire for 10-15 seconds before the circuit breaker kicks in. Although this is less of an issue than with Lionel’s larger transformers, a 1033, 1044 or 4090 still has enough power to melt wire and make it smoke or even catch fire.

Proper wiring for the 1033 transformer is a bit of a safety issue. It’s not just about preventing voltage drop to keep your train running smoothly. A smooth running train is nice, but safety is a must.

How safe is my computer from hackers?

Dave Farquhar security , , , , ,

On Monday, March 13 at approximately 10:30 AM CST, I will be appearing on KFUO Radio’s Faith and Family program to discuss home computer security with host Andy Bates. One of the questions he’s planning to ask: How can I know how secure my home computer is? Or, to put his question another way, how safe is my computer from hackers?

I’m going to use this space to elaborate ahead of time on some of the things we are going to talk about. We could talk for an hour on any of the questions he’s going to ask, and he gave me three questions and 25 minutes. This is my workaround.

This, fortunately, may be the easiest question to answer and the easiest step to implement.

How easily can someone hack my home computer and steal personal information?

On Monday, March 13 at approximately 10:30 AM CST, I will be appearing on KFUO Radio’s Faith and Family program to discuss home computer security with host Andy Bates. Here’s the scariest question he’s planning to ask: How easily can someone hack my home computer and steal personal information?

Someone asked me that question at work once, except it was about a work computer. I whipped out a copy of a book about Metasploit, flipped to page 137, and started reading. My point was that I could teach this guy how. He didn’t take it well, so I don’t recommend doing that.

My point that I could teach this guy how to do it still stands, though. And I think I could teach Andy how too.
