If you got here, hello!
This page is still pretty rough.
I focus on hardware design, but get my feet pretty wet in several areas.

I've made some of my own utilities and software tools availiable, some released as Free Software:
GPL'd boot loader for microcontrollers: Sloadhost.
The first supported target is the STM32 ARM Cortex M3.
Analog Devices ADUC Family 8051 flash downloader.
Spice 2 to Spice 3 conversion utility (very raw!)
I've done some utilities I've chosen not to officially release, or are owned by clients. A few examples:
Voltage divider and ratio web based resistor chosing tools (availible, un-officially released.)
274x Gerber shifting scripts
DSP control / non-intrusive debug host with GUI.
Image file renamer + Imagemagick resizing caller.
Power module loss simulation in C.
