Tech Know: Atomic testing and robotic beetles

Jesse Smigel's technology art collection includes a robotic beetle, a machine that plays decades-old phone calls and a model of an atomic blast.

He designs gadgets in his Las Vegas studio for his own entertainment and for sale.

Andrew Webb caught up with him as he developed a model of a mushroom cloud for the city's Atomic Testing Museum, which commemorates four decades of nuclear tests in the Nevada desert.
