I specialize in writing embedded code for 8/16 bit processors and DSP chips. Forth and assembly language are my major languages, but I also write in C, AWK, Fortran, VB, Postscript, LUA and assorted others when required.

Engineering Design

I design analog systems and microprocessor embedded systems. I used CAD tools for pcboard layout, magnetic FEA, Spice (integrated into the schematic capture system I use). In addition I do spreadsheets, graphics, presentations, report writing, and grant proposal writing.

Professional Societies

I am a long term member of the IEEE, a member of the SAE, and a past long term member of both the AES and the ACM.
