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.

Repair a Lionel train motor

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.

All about the Lionel RW transformer

Dave Farquhar Toy trains February 13, 2017August 17, 2018american flyer, home depot, KW, lionel, LW, marx, power cord, Standard Gauge, tin, troubleshooting

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.

Lenovo Thinkcentre M58 upgrades

Dave Farquhar Hardware February 10, 2017June 5, 2018Broadcom, intel, Intel Core, lenovo, nvidia, Windows 10

I picked up an off-lease Lenovo Thinkcentre M58 over the weekend. Based on the date code on the hard drive, this one dates to 2010. It’s a serviceable machine. You have a few options when it comes to Lenovo Thinkcentre M58 upgrades. I wouldn’t necessarily use one as a basis for a $100 gaming PC but you can make a great general purpose home PC out of one.

When KB Toys closed

When KB Toys closed is a relative question. While KB Toys went out of business in 2009, the store closest to you may have closed earlier than that. It was a sad end for a staple of my childhood, and possibly yours. KB Toys isn’t the only toy store to go out of business of course, but it was one of the more notable ones.

Optimize Windows 10 for better performance

Dave Farquhar Windows February 8, 2017March 11, 20241990s, antivirus, ccleaner, chrome, defragmenter, Disk Cleanup, firefox, intel, micron, print spooler, ramdisk, receipt, Task Manager, unnecessary services, Windows 10, windows 7, windows 98, xbox

When I first installed it, I thought it was pretty pointless to try to optimize Windows 10. Of course, I installed it from scratch on a computer with an SSD and 16 gigs of RAM. Then I upgraded a couple of computers from Windows 7 to Windows 10, and I started to see why some people might not like Windows 10 all that much.

Upgraded systems almost always run slow, but I’d forgotten how much slower. And while you didn’t have to do much to Windows 7 to make it fast–that’s one reason people liked it–I find some Windows 10 optimization seems to be necessary. But don’t visit dodgy sites like downloadmoreram.com. Follow these tips for things that actually work.

Is peel and stick tile any good?

Dave Farquhar DIY February 7, 2017March 13, 2021baseboards, cheap stuff

Is peel and stick tile any good? That’s a fair question, considering its low cost. And if you just buy the cheapest peel and stick you can find and slap it down without any preparation or thought, you probably won’t be very happy with it.

That said, if you do good prep work and think about it, you may find peel and stick vinyl tile more durable than costlier floor types.

All about the Lionel KW

Dave Farquhar Toy trains February 6, 2017August 1, 20171950s, 1960s, american flyer, diodes, KW, lionel, LW, marx, postwar lionel

The Lionel KW is the second most powerful, and second most popular Lionel transformer of the 1950s and 1960s. If the Lionel ZW was Lionel’s Cadillac, the KW was Lionel’s Buick. It was a 190-watt transformer and Lionel sold it from 1950 to 1965. It replaced Lionel’s 150-watt ZW lookalike, the VW.

Finding original KW instructions or an original KW manual online is a bit difficult, but there’s plenty the original instructions don’t mention.

Commodore 1541 vs clones

Dave Farquhar Retro Computing February 3, 2017November 15, 20241541, capacitors, commodore, MOS, power brick

The battle of the Commodore 1541 vs clones existed because Commodore’s early track record was rather imperfect.

Commodore’s 1541 floppy disk drive was the first consumer disk drive that cost less than $300, so it has an important place in computing history.

What some people forget is that while it broke new ground, its early owners loved to hate it. It was slow, it was loud, and ran hot. Early units were unreliable too. And to add insult to injury, in 1982 and 1983, Commodore couldn’t build them fast enough to keep up with demand. Even though it had problems, people were eager to buy it. (Disk drives for other computers tended to be problematic too, in this young industry.)

The 1541’s problems led to a number of clones that tried to be a little bit better.

A 4inkjets review: recommended

It’s not as easy as it could be to find a 4inkjets review, so I thought I’d write one myself. I’ve been buying from 4inkjets.com for more than a decade and I recommend them. Here’s why.
