To produce a modification that provides automated locking of the Scorpios central locking system upon a preset speed threshold. This provides increased security and safety. Various methods are available to calculate the velocity of an object; here we only need concern ourselves with Speed (i. e. no direction or sign of direction is required). An el

ectrical generator usually referred to as a tacho or tachometer is one possibility; these devices provide voltage dependant on speed of a rotating shaft. A second method is to count pulses produced in a revolution of a rotating shaft and the technology to do this can consist of either a switch, optical or inductive methods, or monitoring a toothed wheel connected to the shaft where the wheel may have one or more teeth depending on the required revolution in one rotation of the shaft. Thirdly a similar, but usually more accurate method is to use an encoder; this is an optical device that can either return absolute position or pulses per degree of movement. (For direction out of phase signals are required). In common with most cars today, the Ford Scorpio 95+, has a Vehicle Speed Sensor or VSS built into its Gearbox. The VSS works on the pulse counting method and the signal is used for the Speedometer, Climate Control, Radio AVC, Cruise Control etc. (Interestingly some new car designs actually use one of the ABS sensors as the VSS. ) The VSS provides a 2. 2HZ per MPH square wave pulse (around 2 pulses per second for every MPH of motion). This gives a resolution of 0. 5MPH. (But due to other factors, the Scorpios Speedometer will not be this accurate - the Speedometer exhibits some non linear characteristics). Some extra features are provided, including two selectable Speed Alarms and Re-locking after the doors open and the...
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.....
