Hi, All, My name is Keith, and I have lived in Romania for many years. Trained as Electronics Engineer, then worked on Radar & Communications and some very early computers and programming.. In later years I became a Satellite Systems Engineer, and worked for the European Space Agency, then later for the UN. Many other companies as a consultant between times. Current interests are in simple CNC machines. Although not directly connected with modelling, I have been working intermittently on developing methods and software to produce milled PCBs as simply and cheaply as possible.
