design and development engineer:-
GEC Industrial Controls (Kidsgrove 1982-1986)
Powernetics (Loughboro 1986-1990)
Pektron (Derby 1990-1992)
Erskine Systems (Scarborough 1992-2000)

Typical services I offer are:-

• Electronic Circuit Design
• Consultancy/Advice:- As and when needed priced by the hour/day.
• Existing products and support issues

• Electronic/product design reviews
• Electronic equipment FMEA’s and single fault test plans
• Power electronics design/development and assistance in the same.
• Switched Mode Power Supply (SMPS) design and development assistance.
• Circuit simulation and feasibility studies.
• EMC compliance troubleshooting assistance
• Technical documentation. Product specifications, test specifications, product operating specifications, circuit design description.
• Test procedures.
• Design Review assistance (from a 3rd party point of view)
• General electronic development “bench” testing
• Design and verification testing
• Component reliability issues
• Design to cost exercises
