High quality piece of CW art & technology. Manufactured in 1967 in the USA. Bought from an internet auction in 2006.
The challenger. Homebrew with low tech tools & cheap materials in 2007.
A hacksaw blade is used for the shaft/pendulum. Ordinary screws act as contacts and adjustments.
Alligator clip's position determines the dot speed.
