On the face of it, making a clock that displays the time by moving a pointer along a linear scale shouldn’t be too hard. After all, steppers and linear drives should do the job in a jiffy.

You already know that the size of an enlargement is described by its scale factor. For example, a scale factor of 2 means that the side-lengths of the new shape are twice the side-lengths of the ...

Here’s a third model — the linear clock. [Jan Derogee] came up ... moving as the stepper rotates it. There are scales flanking the vertical rod, with the morning hours going up the left ...

The size of an enlargement/reduction is described by its scale factor. For example, a scale factor of 2 means that the new shape is twice the size of the original. A scale factor of 3 means that ...

The logarithmic scale used initially here allows for an easier comparison of the exoplanets. The linear scale shows how shallow the habitability zone is.

The two companies are billing it as a “first” for the U.S. market; Fox-owned stations have successfully tested the solution ...
