Machining a horizontal Stirling engine - Hack a Day

Machining a horizontal Stirling engine

Satisfy your need to view some quality machining by looking through this Stirling engine worklog. We’ve seen these engines used a few other times in creating electricity from solar energy, powering a car, and even built from aluminum cans. [David Morrow] built this rendition to push the limits of his machining skills. We’d say he succeeded. The finished piece should run with the help of a heat source such as a candle. There’s no video of this engine, but we’ve embedded a clip of a similar device after the break in order to give you an idea of how this would work.

CD/DVD -R +R RW – what does it all mean ?

One of our readers (in our suggestion box) asked for a walkthrough on the different types of CD and DVD.

Unfortunately, a full description of the differences between all of the CD and DVD formats would fill an entire book. There are many, many different types of physical media, methods for storing the data, methods for writing the data and media formats (MPEG-2, MP3, AVI, MP4, etc.)

But… since most people use just a few of the CD/DVD formats, we'll cover just those. The most common formats are generically known as CD-ROM, DVD-ROM, CD-R, CD-RW, DVD-R, DVD+R, DVD-RW, CD-Audio, DVD-Video, and the newer HD DVD and Blu-ray discs.

Vocabulary

First off we need to define a few expressions and words.

• Burning – This is the process used to store data on the media. Which means we burn "holes" in the writable layer inside the disk.
• Session - "Period of time in which something occurs". Which translated means a file or files added in the same operation.
• Single Session – All files on disk are added in one operation.
• Multi Session – Several sessions on one disk.
