Eagle DIY design rules

  • October 12, 2010 18:45

After a few years of abstinence I designed a printed-circuit board again using Eagle. After that I printed out the design, exposed the board to UV light, etched, and drilled it. Everything went pretty well until I started the actual soldering. The restrings–the green circles in the image–were too small which made it awfully hard…

‘Block-centered’ alignment inside LaTeX tables

  • July 15, 2010 19:55

By default LaTeX tables allow three basic types of column alignment: Left-aligned, centered, and right-aligned. Sometimes neither of these choices looks very good, particularly if the column header is wider than the contents of the column body. Several packages exist to deal with this issue. However, they are restricted to figures and don’t work with text in the table body. Using the eqparbox package it’s possible to define a new column type which i.e. right-aligns the column’s contents and then collectively centers the whole block in regard to the column header. After describing the general idea this article also shows how to avoid minor horizontal or vertical misalignments like those introduced by the microtype package.

LaTeX nuisances (I): Space width after an abbreviation

When writing English text, LaTeX adds a larger space after the end of a sentence than between words. This is in accordance with local typographic standards. Things get complicated when you let a machine decide what exactly makes up the end of a sentence.

Perfectly horizontal annotation lines in TikZ

Let’s assume you have two coordinates or nodes in your TikZ picture. You now want to add an annotation to identify the distance between these two points. However, you only want to show the distance along the x-axis whereas you don’t care for the distance along the y-axis. This means that you expect a straight horizontal line.

This article will show you how to achieve that goal without any need to manually tweak coordinates.
