Simple Voltage controlled current source with grounded source and load

This is a Simple Voltage controlled current source with grounded source and load. This is a simple, precise voltage-controlled current source. Bipolar supplies will permit bipolar output. Configurations featuring a grounded voltage- control source and a grounded load are usually more complex and depend upon several components for stability.Voltage-controlled-current-source-with-grounded-source-and-load. In this circuit, accuracy and stability almost entirely depend upon the 100-0 shunt.

When cell phone jammer switches on and starts working

When cell phone jammer switches on and starts working.
The shell mold cavity and core materials to use wear high hardness mirror mold steel. Mold also good material intensity and use standard mold base, another like the top tube mandrel also use the standard, in order to improve the quality and speed of the mold manufacturing. The choice of mold material, specifically to see the Table of the chapter of the book material. Materials, heat treatment of the mold material. Means of heat treatment of the mold material heat treatment of plastic mold materials commonly used in tempering, carburizing, quenching. The heat treatment is conducive to metal machining, to improve the machining accuracy, surface hardness, wear resistance and stability. For example, we can often see a phenomenon: the new mold parts to do good, do 1-2 million. It is convenient to charge cell phone jammer .Faults of cell phone jammer can be solved as soon as possible
Open before and after the shell will damage the lack of any assembly of components can not be missing any parts assembly prototype hooks, and shell assembly, the parts must be complete, experience tells us: that the parts often less fitted, after that part is a problem. And structure of the assembly not only focus on the assembly structure, the same concern with the structure of the PCBA and connector, and a large, high components. A good approach is in strict accordance with the BOM and assembly diagram to do, so easy to find problems. Measurement and assembly of prototype size you want real-time to make a record, otherwise easily forgotten. Specific assembly and test Table 2-5 phone prototype structure assembly Checklist prototype assembly inspection is not only a product quality inspection.
Missed drop is the actual accident situation occurs most frequently use their mobile phones, drop test reliability of the test structure design stiffness and strength test. In the drop test height of 1m, the force is about 10 times its weight chassis, so a good estimate of the structural parts and packaging design stiffness and strength. The drop is more common to test the battery off, so the shell of the card after the battery into the structure of the extrusion force is to be strictly calculated. The structural design of these trials need to understand the methods and principles to guide the design and improvement of the design. The content of these trials the implementation of the responsibility of the professional engineers of the quality management department. The workshop has issued the newest model of cell phone jammer .It is along the thread on the host of cell phone jammer

Current Controlled Boost LED Driver and Black Soldermasks

The MAX16834 is a neat little chip (its not the only one, there are plenty of others out there) that allows high efficiency designs for LED string driving. It provides a platform for a Buck or Boost converter design, as well as brightness adjustment via analog/PWM input pins, as well as a fault output (in case of open/short circuits for example) and also diverse other functionalities that can be quite useful.

Burglar Alarm Using LDR and BC 548

Description

Circuit showing a Burglar Alarm.Here we have used a ldr and a switching transistor for making this circuit
.When the light coming towards the ldr during the period the ldr have low resistance so the buzzer will on.When the light going away the ldr during the period the ldr have high resistance so the transistor will off.Here you need a 12 volt power supply

Components Required

Resistor

10 k(preset)

Transistor

BC 548

LDR

Buzzer
