Laser Shooting Range

A shooting range made of transducers that pick up the normal intensity of LASER beams coming out of a normal source. The shooting range should provide the user with a LASER gun, which the user will point towards specific targets. There should be at least 4 targets, and all of them should be switching randomly from one to another after a fixed time period. The person gets a point if he points accurately towards the target that is currently switched on.

Water Tank Control Mechanism

A water-tank fill-up and overflow control mechanism with alarm. A circuit needs to be designed that displays the present level of water in the tank. The circuit also opens an outlet valve when the level in the tank exceeds a particular level, and finally opens the inlet valve when the water in the tank falls below a particular level.

A circuit is required that would act like a bridge between the electrical appliance in the house and the land-line telephone set.

The transition from one type of pulse to the next must always occur at the 1-sec boundary. A detector circuit should be able to successfully detect all pulses with a period less than 1 sec (i.e. all valid pulses) as well as pulses with a period greater than 1 sec (all invalid pulses).
