troubleshooting of wheel and tyre

In the article “Wheel and Tyre Troubleshooting” we will discuss the most common troubles occurring on account of wheels and tyres are discussed below, there are altogether thirteen points which we will have to know while troubleshooting wheel and tyre: Wheel bounce or Tramp (Figure 1) The most obvious reason for this is the eccentricity of the wheel and tyre. If on checking, eccentricity is not found, the defect may be due to incorrect tyre pressure, statically unbalanced wheels or statically unbalanced brake drum. To determine which particular wheel is…

troubleshooting of automobile light system

The following are the main Automobile Lighting System Troubleshooting experienced in the lighting system of an automobile. A few examples of this trouble are given here. Example No light, Dim light, Lamplight but gradually fade out. Here also we had included trends for automotive lighting. No light | Automobile Lighting System Troubleshooting This may be due to the following reasons: Blown-up the fuse. If this is found to be the reason, then before replacement the basic cause of the blowing up (which may be a short-circuit somewhere) must be determined and…

Electronic Fuse Using Op-amp 741

Engineeering Projects
op-amp 741 based electronic fuse

Here is an electronic fuse using op-amp 741 which features slow-blow properties, a variable current limit, and a ‘live’ indication of its operation. Moreover, it is simple to restore. The electronic fuse using op-amp 741 allows the gadget to draw a higher current initially but keeps a watch on it. if the gadget continues to draw more current beyond the set time limit, it disconnects the supply. The fuse, therefore, acts as a cut-out and indicates this by a neon glow. It is replaced by simply resetting the circuit once.…

RFID Based Security System Using Microcontroller AT89C52 Different concepts of security systems have flourished along with different techniques and different types of equipment. RFID; Radio-Frequency identification (RFID) is another achievement we are relying on for optimum security facility in multiple projects. It makes use of electromagnetic fields to detect unique tags assigned to objects in the vicinity. There is a reason why it has mustered more popularity in comparison to other security systems that use bar codes and conventional methods. It is because RFID traces tags hidden inside objects, unlike…

circuit diagram of frequency counter

Frequency Counter Schematic using Microcontroller AT89C51 is a simple yet mostly used frequency counter schematic used. The reason behind its simplicity also lies somewhere in the fact that this project uses only two components-AT89C2051 microcontrollers and a 16*2 LCD. Frequency is a crucial subject matter in every project. Precise and accurate frequency generation is another challenge we face in varieties of project design. As per the design of this project, this circuit can withstand frequency ranges between 1 Hz to ~16.5 Mhz, and the rest depends on the characteristics of…
