I am a former professional software developer (now a system admin) with an interest in everything that is about making hardware work. In the course of my work, I have programmed device drivers and services on Windows and linux.

I have written firmware for embedded devices in C and assembly language, and have designed and implemented real-time applications for testing of satellite payload equipment.

Generally, finding out how to interface hardware with software is my hobby and job.
