Design Types

Call me today and give me an overview of your idea. I'll let you know if it's something I can tackle, and what the approximate cost would be for it to be designed and prototyped.

I have experience with both analog & digital. Audio filters to full RF rx & tx circuits. Microprocessor design to microcontroller programming. I can write any PC software required for interfacing and data-exchange and design any web-interface required.
