I replaced an outlet with a GFCI and my light switch quit working

Dave Farquhar Landlording ,

I once had an electrical outlet with a light switch next to it, in a bathroom. When I replaced the outlet with a GFCI, the light switch quit working.

When you have a GFCI and a light switch is involved, you have to wire things a bit differently so it all works.

Here’s how I fixed it, using a length of wire (use black, or if you only have white wire, put some electrical tape on it) and a wire nut.

Department 56 scale: The definitive guide

Department 56 scale: The definitive guide

The breadth of Department 56 product lines, such as Department 56 Snow Village, is rather extensive, but there are items they don’t produce and likely never will. If you want to complete your village with other items, or use Department 56 in other settings, such as a train layout, then scale might matter to you—and Department 56 scale is undefined. Here’s how to make sure the things you want to use together will go together, size-wise.

The answer, by Department 56’s own admission, is that it varies. But since I see the question come up again and again, I’m going to tackle it. It varies, but there’s a method to it the madness.

How to disassemble a Marx 999 locomotive

Disassembling a Marx 999 locomotive isn’t too difficult, and it’s easier than the Marx 666, but it helps to have some instructions.

The nice thing about the 999 is that if you can disassemble it, there’s a long, long list of Marx locomotives that disassemble in pretty much the same way: the Commodore Vanderbilt, the Mercury, the tin Canadian Pacific 391, and the tin steamers 592, 593, 594, 833, 897, 898, and 994.

Marx designed its trains so that a father or older brother could service them, so it comes apart with simple household tools, and you can get most of what you’ll need to service it at the nearest hardware store, with the probable exception of the bulb for the headlight.

Specs for the Lionel 6-12053 accessory wire–and how to make your own

Dave Farquhar Toy trains ,

A question the other day caught me off guard–how long is the Lionel 6-12053 accessory wire for Fastrack? I know a lot of random stuff off the top of my head, but I had to do some digging to find out it was 26 inches long–approximately.

Intended to clip onto leads on the underside of a Fastrack section, you can use it to power an accessory, as an additional power drop, or as an extension if the stock wires on your terminal section are too short.

If you need a different length, or need several and just don’t want to pay Lionel’s price, you can also make your own.

How to disassemble a Marx 666 locomotive

Disassembling a postwar Marx 666 locomotive, or its plastic counterpart the 1666, isn’t too difficult, but it helps to have some instructions.

Marx designed its trains so that a father or older brother could service them, so it comes apart with simple household tools, and you can get most of what you’ll need to service it at the nearest hardware or auto parts store, with the exception of the bulb for the headlight.

How to repair small plastic parts

Dave Farquhar Model Building ,

Gluing small plastic parts back together is a two-part challenge: First you have to find a suitable glue, and then you have to find a way to hold the pieces together while the glue cures.

Challenging need not be impossible though.

Whitelist Java to provide better security and a better user experience

Dave Farquhar security, Windows , , ,

One of the best things you can do to improve your security in a corporate environment is to limit the use of Java, or whitelist Java. Undoubtedly there will be one or more legacy web applications your company uses that require Java, and it’s almost inevitable that at least two of them will be certified for one and only one version of the JRE, and it won’t be the same one.

Believe it or not there’s a solution to the problem of conflicting JREs, but it took me years to find it, because I had no idea that Oracle called it “Deployment Rule Set.” The secret’s out now. If you run Java, and you want security, you need Deployment Rule Set.

Model train won’t move? Here’s the fix

A common problem with HO, N, and other scales of electric train that run on DC power is that when you put them on the track, they light up but don’t move and instead make a weird noise. If your model train won’t move, I can tell you how to fix it. Here are my tricks for model train locomotive troubleshooting.

The cure is usually simple, involving switching a couple of wires.

Commodore 64 vs VIC-20

Commodore 64 vs VIC-20

How do you compare the Commodore 64 vs VIC-20?

The Commodore 64 and its predecessor, the VIC-20, look a lot alike, and the VIC-20’s design certainly influenced the 64. The 64 is the best selling computer model of all time, and I argue the VIC-20 was the first really successful home computer. The success of the two machines allowed Commodore to surpass Radio Shack as the sales leader in the computer industry. Yes, both Commodore and Radio Shack outsold Apple.

But even though the two machines are closely related, there are significant differences between them. It’s important to remember that in the 1980s, two years was a comparatively long time because the market was moving so fast. Plus, the VIC-20 was always supposed to be an entry-level machine. In 1982, the 64 was supposed to be fairly high-end. Let’s compare and contrast the two venerable machines.

Cleaning Lionel Fastrack

Lionel Fastrack has some advantages, but after a decade or so of using it under a Christmas tree, I have to say staying clean isn’t one of them. Here are the secrets of cleaning Lionel Fastrack safely.
