How often should you replace thermal paste?

We usually only think about thermal paste during new system builds. But you may not know that thermal paste dries out over time and needs to be replaced. So how often should you replace thermal paste? And why do you need to?

How long thermal paste lasts depends on how hard you use your computer. It’s best to replace it every 3-5 years or so, if you keep your system that long, but there are other times it’s a good idea to replace it too.

Convert AVI to WMV for free. No fooling.

Dave Farquhar Windows

I see tons of guides out there claiming to tell you how to convert AVI to WMV for free. Then they give you instructions that don’t work before pitching you some $80 tool to do it. You can’t convert AVI to WMV with VLC, but you can do it with another free tool called FFMPEG. Here’s how.

The most reliable free way to convert AVI files to WMV for free is using a command line tool called FFMPEG. It’s not as easy as having a GUI, but it works. WMV isn’t the ideal video file format, but there are times you need it.

O27 scale

O27 scale

O27 scale is something of a misnomer. If you’re looking for scale fidelity, you won’t find a lot of it in O27, regardless of manufacturer. But there are still some general guidelines you can follow.

O27 is the designation for entry level O gauge trains that are smaller and less expensive, though capable of running on the same track. But their scale can be confusing, even for experienced hobbyists.

IBM PS/Valuepoint

IBM PS/Valuepoint

The IBM PS/Valuepoint was IBM’s attempt to address public objections to the IBM PS/2 series. Introduced in October 1992, they were the most clone-like IBM business desktops since the IBM PC/AT. As the name suggests, they were designed to be price competitive with the higher-end PC clones like a Compaq Deskpro. IBM sold them alongside the PS/1 and PS/2.

Genesis vs SNES: Battle of the 16-bit consoles

The Sega Genesis and Nintendo SNES were natural rivals. They weren’t the only 16-bit game consoles of their era, but they ended up being the two most popular. Sega leapfrogged Nintendo with the Genesis, and the SNES was Nintendo’s answer. Let’s take a look at the Genesis vs SNES.

Overall the SNES was the better console of the two and its popularity reflects that. But the Genesis had its moments, so it retains a following today, even if it has to stand in the shadow of the SNES.

Paint 3D printed models: Here’s how

I recently acquired a 3D printed door for my Commodore 1084 monitor. It was missing its original. Of course, it came in white. I can live without an imperfect match, but I want something closer than white. But can you paint 3D printed objects? Yes you can. Here’s how to paint 3D printed models.

Plastic can be tricky to paint, but 3D prints tend to have some texture, and that makes it easier for paint to bond to them than molded plastic. Still, some prep work is still a good idea.

S gauge vs O gauge

The S gauge vs O gauge rivalry is certainly a natural one. They were the two most popular sizes of electric train immediately after World War II, before HO scale eclipsed both of them in the later half of the 1950s. Let’s take a look at the two standards for trains, what’s different about them, and see what kind of common ground we can find between them.

What is a cold solder joint?

Years ago, my monitor broke. Back then we had repair shops for such things. I called one and described the symptoms I was having. “Sounds like it could be a cold solder joint. Bring it in,” he said. But what is a cold solder joint? Isn’t solder hot?

A cold solder joint doesn’t refer to temperature, but rather, lack of electrical conductivity. A cold solder joint is a solder connection that isn’t conducting electricity the way it should.

Why did paint have lead in it?

Why did paint have lead in it?

Does paint have lead in it? It’s not supposed to anymore, because it’s a serious safety issue. But there was a time when it did, and people might even pay extra for more of it. So why did paint have lead in it, and what can you do about it now?

Ingesting lead lowers IQ and causes other health issues. That’s why the United States banned lead paint for residential use in 1978. However, certain industrial paints, such as the paints used for street markings, can still contain lead even today.
