The other day we went to unplug a lamp so we could plug a vacuum cleaner in. But something didn’t quite feel right. When we looked at the plug, we could see why. One of the prongs was missing. When we looked at the outlet, the prong was still there. There’s some bad, or at least time-wasting, advice out there on how to fix a prong stuck in an outlet or socket. Here’s how we fixed it.
Is powerline networking safe? It may sound strange to send computer networking signals down the same wire you use to get electricity. Here’s what you need to know.
You can get used 8440p laptops pretty cheaply because HP Elitebook 8440p overheating is rather common. Symptoms of overheating include unexpected reboots, shutting down, and bluescreens.
The problems with the cooling system are unfortunate. They have nice keyboards and they’re easy to work on, so they’d be nice laptops if they didn’t overheat so much. Here’s how to improve their cooling so you can get a bargain.
The Lionel e-unit was a wonder of ingenuity in the 1930s. But how does a Lionel e-unit work?
I get a lot of inquiries about “the copper piece on a locomotive.” They mean a toy train locomotive. Depending on the make of the train, there may be one copper piece on the motor, or there may be two.
Here’s what those pieces are called, how to find them, and how to care for them.
There are any number of methods out there for cleaning copper contacts, but some of them are safer than others. Here’s my favorite method to thoroughly and safely clean copper contacts. It’s very thorough, safe, and cheap.
The Linksys EA6200 is hard to open or disassemble. But there’s a trick. This trick looks like it will work with other 6000-series routers as well, such as the EA6300, EA6350, and EA6400. Here’s how to disassemble a Linksys EA6200 router.
If you want to fix a Lionel train, what you probably really need to do is repair a Lionel train motor. There isn’t much to the rest of the train.
The motors tend to be pretty rugged and they’ve held up over the years. Most “repairs” are really more of a clean and service job, not unlike taking your car in for an oil change. Here are some general principles to follow when you clean and service a Lionel motor.
The Lionel Multi-control Trainmaster RW is a sturdy tin box of a transformer from early in the postwar era. The presence of a whistle controller is the only thing that really distinguishes it from a prewar transformer. Lionel made it from 1948 to 1954. If you want to know all about the Lionel RW transformer, you’ve come to the right place. You probably won’t find a copy of the original instruction manual online but this will tell you all you need to know.
Vintage Lionel transformers activated the whistle using a rectifier disc. These discs tend to degrade over time. You can expect to pay about $5 for a replacement disc. But a modern diode is much cheaper, works better, and is more reliable. Here’s how to replace a Lionel RW rectifier disc with a diode.
