Disassembling a Lionel 1001, 1060, 8902 or 8302 locomotive isn’t too difficult. The biggest problem is knowing where the three screws are that you have to remove.
These particular locomotives weren’t really designed to be repaired, but there’s some basic work you can do on them with household tools. The 8902 and 8302 locomotives can be cheap sources of a motor for other projects.
The Lionel LW Trainmaster is a 125 watt transformer that Lionel produced from 1955 to 1966. They are reasonably durable and Lionel made them for a long time. That means you can find them easily on the secondary market. They can be expensive if they have their original box and paperwork. But if you just want to run a train and don’t care about the paper, you can get a serviced LW for $50-$60, and an as-is one for under $40. At 125 watts, it’s the most powerful single-handle transformer of the postwar era.
The LW is a quirky transformer so there are some things about if you need to be aware of if you have other Lionel transformers, but as long as you keep those in mind, it’s a fine transformer that will serve you well. The quirks have nothing at all to do with reliability. Lionel just designed its layout a bit differently than many of their other models. In some ways it’s the ideal accessory transformer. We’ll cover that later.
One thing to keep in mind: Unplug the LW when you’re not using it. It doesn’t have its own power switch. I plug my transformers into a power strip and turn all of them on and off with the strip’s on/off switch.
A friend was replacing a light fixture in his bathroom and ran into something confusing–a red wire in the electrical box along with the usual black and white wires. And when he hooked up his new light fixture, he did what I would expect the majority of homeowners to do–he connected the white wire on the fixture to the white wires in the box, and the black wire on the fixture to the black wires in the box. And then his light switch wouldn’t work–the light stayed on all the time.
He was on the right track when he asked what the red wire is for. That was the key to solving his problem.
When I replace garbage disposals, I prefer to use a power cord rather than hardwire them straight into the wall. The thing is, I don’t like paying $12 for the official power cord, which is chintzy looking and, frankly, looks under spec’ed. Instead, I prefer to use a computer power cord on a garbage disposal.
The label on a 1/3 HP Insinkerator Badger says it’s rated for 5.8 amps at 125 volts. I found a computer power cord in my stash that was rated for 10 amps at 125 volts. It’s overkill, but when it comes to electricity, overkill is good. Best of all, it let me repurpose something I’d already paid for and was probably never going to use.
The Enerlites Top Greener HOSS is an occupancy sensor switch without ground wire requirements, and it’s pretty cheap too, at $12. A Lutron switch costs almost twice as much.
But the HOSS does come with some compromises. The HOSS does require a neutral (white) wire. But most switch boxes will have the whites in there and accessible, so that’s not a big deal. It’s also a bit trickier to wire than a Lutron, and it doesn’t look as nice.
That said, it’s nice to have an option for older houses that may not have a ground connection available. People in older houses need energy savings too. Read more
Let’s talk about wiring tricks for Lionel Fastrack. Specifically, let’s talk about making your own Fastrack terminal sections instead of buying them.
It’s a good idea to run wires to your track every so often. The rules vary. I’ve heard every 3 track joints, starting over after each switch. I’ve also heard every 3-4 feet. Regardless of who you believe, the single drop you’re probably using is inadequate. Adding extra drops will cause your train’s speed to remain a lot more smooth and constant.
Fastrack terminal sections–the sections that come with wires attached from the factory–are expensive. But any section has the terminals on the underside of the track to add your own wires; you just need the connector. Read more
I wrote a long, long time ago about my adventures trying to find a wall wart for my old 8-port Netgear dual-speed hub. The other day I stumbled across a novel idea for a replacement.
I won’t rehash how you determine whether a unit is a suitable replacement–read the above link if you’re curious–but suffice it to say a $5 universal adapter from Kmart is fine for my answering machine or my cordless phone and can probably provide the 5 volts my Netgear needs, but my Netgear also needs 3 amps and the universal adapter I keep around can only deliver 20% of that. The beefiest 5v unit I could find at Radio Shack could only deliver 1.5 amps.
A PC power supply delivers 5V and 12V on its hard drive connectors. And PC power supplies deliver plenty of amperage: one of mine will deliver 25 amps on its 5V line, and 10 amps on its 12V line.
In a pinch, I could just obtain a suitable plug barrel that fits my Netgear from Radio Shack, clip the power connector off a dead CPU fan, and solder the plug to the red wire (5 volts) and a black wire (ground), put it in a PC, and use that to run my Netgear hub. The increased power draw would be equivalent to putting three typical PCI cards in the system. Just be sure to wire things right–reverse polarity can kill some devices.
Rather than using one of the PCs I actually use, it would be better to obtain a cheap microATX case, short the green and one of the black wires on the 20-pin motherboard connector with a paper clip, insulate the paper clip with electrical tape, and then wire things up to the drive connectors. Or, for that matter, you could use some of the other leads available on the 20-pin connector if you have a device that needs 3.3 volts (pinout here.) You could also just use a bare ATX power supply with a paper clip connecting the green wire and one of the black wires on the 20-pin motherboard connector, if you’re into the ghetto look.
An AT power supply would also work and it offers the advantage of being really cheap and common (here’s a nice writeup about an AT power supply’s capabilities), but most AT boxes require you to hook up enough 5-volt devices to chew up about 20% of its rating on that power rail before they’ll power up. I have a 200-watt AT power supply that delivers 20 amps on its 5-volt rail, so my 3-watt Netgear hub probably wouldn’t be quite enough on its own. So it might be necessary to either connect an obsolete motherboard to the power supply or connect a 1-ohm resistor between a +5 lead and ground, if you don’t have a plethora of power-hungry 5-volt devices to plug in.
But PC power supplies provide a cheap and commonly available way to replace odd wall warts, or at the very least, to reduce the clutter around the computer room.
