Flashing Neon Circuit diagram Circuit Schematic With Explanation

This circuit will be a fantastic circuit for Vehicle lovers Because this circuit can up grade the out look of your Vehicle. This circuit is nothing but a Flashing Neon circuit diagram.This circuit can be operated with 90V.You can change the frequency of this circuit by changing the values of C and R.Large values reduce frequency of this circuit.







Note

# Use Ne 2 or Ne 51

# This circuit can be operated with 90v

Touch sensitive Circuit Schematic With Explanation

Here I have design a touch sensitive circuit diagram.For this circuit I have used a common transistor BC 547.Normally this circuit can be operated with 4.5 to 6 v.I suppose you will be able to do lots of things with this.I have used this circuit for my room light.So you also can use this circuit for your room light.





Note

# Use a pcb to build this circuit

# Don't supply more than 6V

smoke sensitive circuit diagram Circuit Schematic With Explanation

Here I am going to introduce you a very important circuit.It is nothing but a smoke sensitive circuit .In the market we can see there are lots of expensive smoke sensitive kits.But I'm going to give you a very simple method to make a smoke detector.Here i have used a dark sensitive circuit.When the smoke goes via LEDs and LDR it will generates a sound.If you want to operate another circuit firstly remove the speaker and add a really for there.then you can operate your circuit through that really.





Note

# Build this circuit on pcb

# Don't use more than 9V

#Use Blue colour LEDs

Perpetual top Levitation Toy

Perpetual top Levitation Toy
The point of the perpetual top levitation toy is simply that it continues spinning forever, and the challenge is to understand the driving mechanism. The top is made of plastic, and contains embedded in it a small permanent magnet, oriented perpendicular to the spin axis of the top. The base contains a transistor and a coil with two windings, the assembly being driven by a 9-volt power supply. A schematic of the electrical circuit is shown in the figure.
As one pole of the magnet (say the south pole) approaches the coil, a current in induced in winding A, in such a direction as to make the base of the transistor (an NPN) go positive. That makes the emitter-collector current flow through winding B, in the opposite direction to A. The current through B is larger than that of A (due to the amplification of the transistor), so by Lenz's law the magnet pole will be attracted to the coil.

How A Magnetic Linear Accelerator used in toy?

A Magnetic Linear Accelerator

This very simple toy uses a magnetic chain reaction to launch a steel marble at a target at high speed. The toy is very simple to build, going together in minutes, and is very simple to understand and explain, and yet fascinating to watch and to use.

The photo above shows six frames of video showing the gauss rifle in action. Each frame shows 1/30th of a second. In the first frame, a steel ball starts rolling towards a magnet taped to a wooden ruler. In the second frame, a second ball can be seen speeding between the rightmost two magnets. By the third frame, the accelerator has sped up so much that the ball that is seen leaving the left side of the device is just a blur as it smashes into the target. One ball, starting at rest, has caused another ball to leave the device at a very high speed.
