The Raspberry Pi is a wonder worker!

Do you have a Raspberry Pi tucked away in a box somewhere because you are not sure what to do with it after the novelty wore off?

Here are five free, useful purposes for the humble Pi.

Run Windows93 in Linux!

📅 October 3, 2017
Windows Ninety-WHAT?

Do you idle your time away watching pointless cat videos on YouTube like most netizens?

Yes? Really?

Then, why not idle your time away while reminiscing the “good ol’ computing days” with the one and only Windows93 operating system?

“Windows93? Never heard of it. Is this a joke?”

Nope. It really exists.

“Which? The joke or Windows93?”

Both.

And the best part…it works in Linux!

Hard Drive Caching in Windows 7

📅 May 6, 2017
After experiencing good success in Linux using RapidDisk and Flashcache (on older kernels) to speed up mechanical hard drive reads, I thought it would be fun to discover if such software existed for Windows.

Is it possible to install hard drive caching software in Windows 7? How would it perform?

I tried four programs, PrimoCache, HDDTurbo, SuperCache 6, and eboostr, and tested reads using CrystalDiskMark. Here are my results.

Better PlayStation Video with RGB SCART

📅 October 15, 2016
ff7-1-ps1-scart-comboYearning to play games on an original PlayStation console but dislike the poor video quality?

Most modern HDTVs available today only offer HDMI and maybe component video inputs — neither of which the PlayStation (PSX/PS1/PSOne) supports.

However, the PSX outputs RGB (red/green/blue) signals through its video output port to produce the best colors and picture quality.

How can we use RGB with today’s HDMI televisions and monitors? This requires two items: a PSX SCART cable and a SCART-to-HDMI converter. With these, we can achieve almost pixel-perfect sharpness and colors from a nearly 20-year-old gaming console.

Reduce a Computer’s Audio Output Line Hum

📅 August 30, 2016
isolator“Why do I hear a faint hum from my computer’s audio output?”

Computers are electrically noisy environments, and all of those wires and fans and whatnot operating at various frequencies can have unpleasant side-effects on a computer’s audio output.

If you enjoy listening to music played from your computer and if you use the computer’s analog stereo outputs (the 3.5mm line out jack) to connect to an external amplifier or receiver, then you have no doubt encountered the low-frequency hum effect.

Not a mere hiss due to a noisy sound card, but a low hummmmmmmmm that is heard consistently whether or not audio is playing and regardless of the volume level.

This can happen with any home audio equipment, not just computers. Often, it is caused by a ground loop, and the best way to reduce or nearly eliminate this hum is to electrically isolate the audio output (from the computer) from the audio input of the receiver/amplifier.

PNY 128G MicroSD vs. Patriot 128G MicroSD

bothcardsPNY or Patriot? PNY or Patriot?

With 128G MicroSD cards falling to near-identical prices, the choice becomes more about performance than cost.

The PNY 128G High Performance MicroSD card and the Patriot 128G LX Series MicroSD card were exactly the same price, so which one offers better read and write speeds? Do they live up to the promises made on the packaging? Are they compatible with Linux? With they work with the Kingston MicroSD reader?
