2.3" readout ULTRA HI-SPEED INPUT MONITOR

Johnny
An Ultra-hi-speed ~100us portable detection monitor that can be multiplexed using up to nine inputs. Commonly used in slot-car racing, swimming meets, game shows or other events where hi-speed error-free detection is required to determine an input status; 1st, 2nd, etc ...9th. Very easy to construct with minimal soldering skills and well redesigned circuit board that formerly used 1" digital displays to 2.3" digital displays as well as allowing for multiple 'input' choices, such as photocell, mechanical or magnetic with the same results! It operates on a single 9-volt Duracell battery for long-term portable use, a feature not often seen with this sort of monitor and, comparatively speaking, similar monitors of this high caliber are sold for much, much more than construction costs of this one and electrically, absolutely no difference in hi-speed operation and perhaps even faster!
