Their first attempt at an electronic system was not very successful.
That system used a power hungry circuit using a solenoid, powered by a large sealed
battery. The battery had to be replaced every few months. Could Wily come up with a
Wily asked some more questions about their system. Their telescope
had a simple single lens. In their electronic prototype, they used a solenoid to
hold open a spring loaded “flapper door” shutter, which opened and closed a light
path in the eyepiece. The solenoid was the major power drain from the battery.
They were very pleased with the new coin acceptance mechanism they switched to in
the prototype and wanted to stay with it. The system was very foolproof and had few
mechanical parts. It accepted only quarters. Other coins dropped through. A simple
switch closure occurred, when a quarter fell into the coin box.
Wily gave some
thought to this system and decided that he could solve the power problem with a tiny
gear motor to move the flapper shutter. He gave the company a rough estimate for
the cost of a working prototype of the timer electronics and the motor control.
They agreed on the price and sent Wily some money to cinch the deal.
