While working on a project for a television program,
several-times-over Gadget Freak John Tindall started tinkering with a pulsejet
engine. Pulsejet engines were used by the Germans during WWII. The technology was
left behind by turbofan jets. But Tindall found the pulsejet well-suited to garage
- and Gadget Freak - tinkering. Apparently there is a wide community of
hobbyists playing with pulsejets at home. Tindall came up with a cyclonic-valve
radial design that makes for smoother airflow. He proved the concept with
plastic and aluminum valves - but the gadget backfired and blew up. Next step, a
These are the toys that inspired budding engineers to try out sublime designs, create miniature structures, and experiment with bizarre contraptions using sets that could be torn down and reconstructed over and over.
