I am an electronics design professional with over 40 years experience in the industry.

I started out building supposedly simple projects using valves (tubes), finding out the practical way that even simple usually has a degree of complexity.

As a teenager I built my own valve/tube superheterodyne radio and an oscilloscope, plus numerous other long forgotten projects (some worked well, others not quite so brilliant!).

For relaxation I design and build HiEnd audio and use a mix of valves/tubes, transformers and sand (i.e. semiconductors).

As an electronics design professional I have mainly worked in the area of Science Instrumentation and Consumer products. Most of what I do is for one off or small volume production where function is normally more important than base costs. I have however also designed for million plus build quantities, which is an interesting challenge as fractions of a Cent per item of materials costs suddenly become significant.

I primarily use Mentor Graphics DxDesigner for schematics and PADS PCB for layout. I also use DesignSpark for small projects that need to be accessible to others.

For 3D CAD I use Alibre/GeoMagic.

Best wishes, TriodeGirl.
