  • Analogue and Digital Electronic circuit design and simulation (ORCAD, PSPICE, Microsim and RS Wire/Promis-e)
  • Motion control systems (servo, stepper, AC/DC, linear motors, motor sizing and simulation)
  • PLC programming (Siemens S5 and S7)
  • PC control (interfacing and programming)
  • Embeded Microcontroller systems (Siemens '167, Interfacing and embedded C programming)
  • Safety circuit design (Machinery directive, extensive experience of interlocks and safety relays)
  • Pneumatic design (Cylinders, valves, sensors and actuators) Field busses (ASI and Devicenet).

For further details, or to discuss a particular project, please contact me by going to the Contact information page.

A lot of this work can be undertaken for clients anywhere by "teleworking" and not just for clients living in the north of Scotland.
