Videos for Engineers

Lego robots have for many years been a favorite pastime for nerds young and old alike.

Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
