Op-Amp Dc Offset Shift Circuit Diagram

This is the simple Op-Amp Dc Offset Shift Circuit Diagram. The dc values of op-amp offsets can`t always be taken for granted when delivering ac outputs. No device is ever exactly symmetrical for maximum positive slew rate versus maximum negative slew rate. Consequently, there is always some range of output slew rates in which the device used limits in one direction more severely than in the other.

What results in rectification of the ac signal and an apparent shift of the dc offset. This test circuit can check for the shift phenomenon. The accompanying table and graph illustrate the results obtained for four devices, all of different types.As frequency and slew rate are increased, the effect can be either relatively abrupt (LF412CN and NE55532N) or relatively gradual (LF358J and TL0820P).

Simple Light Audio Transmitter Circuit Diagram

This is the Simple Light Audio Transmitter Circuit Diagram. In the visible-light transmitter, a 7805 voltage regulator is connected in a variable-voltage configuration, and an audio signal is fed to the common input, to modulate the output voltage. The modulated output voltage is used to transmit intelligence via an incandescent lamp.

Audio Power Amplifier Circuit Diagram

This is the ic based Audio Power Amplifier Circuit Diagram. The LM383 is an audio-power amplifier that is capable of producing up to 8 W of audio output. R1 is essentially a load resistor for the hand-held transceiver`s audio output. R2 can be composed of two fixed resistors in a 10:1 divider arrangement, but using a potentiometer makes it easy to set the amplifier`s maximum gain.

When powered from a vehicle`s electrical system, the amplifier`s +12V power source requires filter L1 to eliminate alternator whine. The LM383 can ·be mounted directly on the heatsink because the mounting tab is at ground potential.

Simple Water-level indicator Circuit Diagram

This is the Simple Water-level indicator Circuit Diagram. n this a warning device WD1 is in series with SCR1. When the liquid level causes a conductive path between the probes, the SCR conducts sounding WD1. The warning device may be a Sonalert (TM), a lamp or a buzzer.D1 acts as a transient suppressor. Press SI to reset the circuit.

How to Made a Stune Gun at Home

There seems to be alot of interest in making home made stun guns these days. Some things need to be said before we go any farther. Home made stun guns like any home made device could be hazardous! Home made devices are fun to build and play with, but use at your own riskI. If you doubt your skills, or need some thing more powerful and dependable, click on a link and have a look around

There is a huge difference between a Stun Gun and a Taser, a stun gun is a contact weapon and a taser fires darts attached to wires. We are Talking about a Stun Gun Here. If you want to learn more about a Taser but. If you are still wanting to build your own stun gun than lets get started.

Assembly of a home made stun gun

The main piece of equioment needed is a disposable camera, make sure it is one with a flash.

#1- carefully open the casing of the camera, but be careful not to damage anything in the process.

#2-Take out the battery to prevent being shocked in case of accidental discharge.

#3-You will need paper clips, that will need to be shortened and attached to each end of the Capacitor. These will act as the wires through which the shock will be emitted.

#4-Put the Battery back in ensuring that you don't touch the wires after it's back in.

#5-Press the flash button on the camera to charge and than use a screw driver to see the results.

essentually the main part of this project is adding wires ( in the form of paper clips ) to each end of the Capacitor.

There really isn't much more to it!

Stun Gun Schematics

This is diagram #1 of a working Stun Gun. You will have to be able to understand electrical circuit diagrams.

Self Made Stun Gun Electrical Diagram

This is another Stun Gun circuit diagram althoe a bit more complex. You will need the ability to read and understand electrical circuit diagrams to assemble a stun gun from these drawings.

Stun Gun Electronics Number Three

This is an even more complex drawing and will require you to have a good understanding of electronics and electrical diagrams to assemble. It should prove to be a challanging project for every one except someone in the Electronics field.

The Reality of self built Stun Guns

Just being able and willing to build a home made Stun Gun doesn't really mean that you actuaslly should.

People that construct home made stun guns have a tendency to want to test them on friends or family. Stun Guns home made or not are not toys and should never be treated as such.

There have been instances of home made stun guns blowing up in peoples hands and medical complications from being burned or shocked.

There is no way of telling what will happen with a home made device of this kind. Caution should always be first and the number one thought should be,

Should I even build the damb thing at all.

Well thats not for me to answer, because if you are determined you would have just found the information your self any way.
