This system includes a processor which may have been a microcontroller but it did not have alarge memory and so an obvious improvment to this system is to use the internal RAM and ROM in a modern microcontroller. Note There are lots of circuit elements here that you can use such as a Xenon strobe light driver. Flowcharts are also included that sho

w the exact sequemce of events to follow to create your own version of the system. Particularly interesting is the method for detecting the gun "shot" (infrared) which switches around transmitter and receiver to acheive a far greater accuracy and simplicity in design. This is key design decision showing an innovative approach to solving the problem. One of the earliest childhood played games involves some type of battle. Whether it be "good guys" against "bad guys", cowboys and indians or cops and robbers, a "shooter" and "target" theme prevails in these basic games. The variations on the shooting-type theme games are numerous, and are based upon the age level of the children involved as well as the sophistication of the equipment available for playing of the game. Guns may be anything from imaginary to realistic looking models of actual firearms. As children grow older, so does the sophistication of the game rules and game equipment. With the technological advances in the electronics field, cowboy and indian shooting games have evolved into sophisticated audio visual games involving battles between planet inhabitants and alien invaders. A battle with the aliens is carried out on a cathode ray tube display in which the sole player controls a joystick or push-button in order to "fight" the enemy. With the advances in audio visual games, the one-on-one individual player interaction and much of the independence of player...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
