USEFUL WOODWORKING
As a youth , Rode would spend most of his free time in his uncle ’ s carpentry workshop , where he made toys and other useful objects that his family could not afford to buy . He made his first pair of skis , teaching aids for secondary school , the box for a radio receiver , and a slide rule that he used throughout his university studies . Many years later he would collaborate on the development of an electronic version of the tool - the HP-35 pocket calculator .
