VGA signal generation hacks

This is continuation to Interesting VGA hacks hacks posting. Interesting VGA hacks hacks was concentrated on using VGA card for nontraditional uses, this posting on the other hand concentrates on generating VGA signals with other hardware than VGA graphics card. It seems that modern microcontrollers are well suited to display information on analog VGA monitors:

Interesting VGA hacks

Let’s continue the VGA theme I started in VGA memories and future posting. Here are some VGA hacking ideas on using VGA graphics adapter for non-traditional uses.
