Abstract
A battery operated electronic drag race simulator includes a casing having hand grips at each side. When an on-off ignition switch is closed, a first light emitting diode (LED) numeric display immediately indicates the maximum engine RPM or tachometer reading that cannot be exceeded for the class of race the player has selected. A race start indicator or "Christmas tree" produces an automatic sequential energization or countdown of a yellow lights followed by the energization of the green start light signifying that a race has officially begun. Depressing a gear pushbutton and then depressing a gas pushbutton, causing a brief tire squeal sound to be produced via a speaker. The gas button causes a varying frequency signal to be generated that produces a sound resembling various engine speeds. A frequency varying signal representative of engine speed during the race is employed to constantly change the RPM reading on the numeric display. If the maximum RPM for the class of race that has been selected is exceeded, a noise signal is produced, causing the speaker to provide a sound resembling that of an engine explosion, and the race is ended immediately. When the race is over, the disp…
