Kalle Hyvönen of DGK Electronics has created a new Inkscape extension that might be handy for all of us robot builders:
I developed an extension for Inkscape which can create optical rotary encoder discs in any size/number of segments. It currently supports single and two-track (quadrature) encoders but I’m going to add support for gray encoded discs as well.

Hershey Text is an Inkscape extension that can render a line of text in one of several stroke-based “engraving” fonts. This extension solves a persistent problem, and one which we have come across in many different contexts: How to easily create simple and readable vector representations of text.
Quick start: Download the latest version of this extension here, and install it like a regular Inkscape extension. Much more information follows.
