AC to DC Conversion using Diode
The AC current flowing in both directions and DC current flows only in one direction.Most of the electronics circuits run on DC power supply and the mains power supply available to us is AC. Hence we need to convert AC into DC for most of the home appliances.

AND Logic Implementation using Diodes
A logic gate is an elementary building block of a digital circuit. Most logic gates have two inputs and one output. At any given moment, every terminal is in one of the two binary conditions low (0) or high (1), represented by different voltage levels. There are various types of logics are available like: AND logic, OR logic, etc.

Automatic street light controller with road power generation
Mechanical Projects, School & Engineering ProjectsAutomatic street light controller with road power generation
We have used a sensor called LDR which has the property to change its resistance according to the intensity of the light. As the intensity of light falling at the LDR increases, its resistance gets decreased and vice versa. Hence the total intensity of light remains constant.
It is one of the most recent power generation concepts. This device is engineered as a practical and useful alternative energy technology for generating clean electricity from the millions of vehicles on our roadways and utilizes this electrical energy efficiently when required.

Bistable multibivrator using Transistor
The Bistable Multivibrator is another type of two state device similar to the Monostable Multivibrator ,but the difference this time is that BOTH states are stable.Bistable Multivibrators have TWO stable states (hence the name: “Bi” meaning two) and maintain a given output state indefinitely unless an external trigger is applied forcing it to change state.

DC light driving circuit using Darlington pair
To drive large number of LEDs for lighting purpose we need transistors of high power. Darlington pair of transistor is commonly used to improve the power performance of general purpose transistors(like BC547). We can see from the circuit diagram , two transistors are connected in such a way to represent a single transistor. The LDR(light dependent resistor ) is also there .

Delay switch using RC circuit
Delay circuits are used to protect elelctronic circuits from abrubt change in the power. These circuits introduce some finite delay before the device gets turn on .Most simple way to implement these circuits is by using capacitors. In this circuit we can see that if we turn on the DC power by closing the switch S1, both the capacitors start charging .

Four Axis Hydraulic JCB using Syringe
- Excavators are heavy construction equipment consisting of a boom, stick, bucket and cab on a rotating platform. It has 4 axis mobility and is capable to pick and place any object. Due to high cost and less availability hydraulic pumps and pistons, we have put our idea in the real life scenario using medical syringes as hydraulic piston.
- This model reaches the great distances to deliver and picks up the heaviest possible object, rotates as well as reaches, grabs, digs and recovers objects.

Four Axis hydraulic JCB using Syringe with Motor
Here, we have used DC Motors for pulling and pushing the syringe lever instead of manual operation. These motors operate with 12 volt dc powered supply using switches. Excavators are heavy construction equipment consisting of a boom, stick, bucket and cab on a rotating platform. It has 4 axis mobility and is capable to pick and place any object. Due to high cost and less availability hydraulic pumps and pistons, we have put our idea in the real life scenario using medical syringes as hydraulic piston.

Four Legged Walking Machine
Ask For Availability :- https://bit.ly/2pJeQlD
This machine with legs can travel over all the obstacles that come in its path with an adequate speed. There are many types of locomotion like wheels, legs, crawlers, etc. Among these types, the legged locomotion is the most suitable system to negotiate rough surface, because it has an advantage of selecting the ground contacting points of the foot freely, self balanced, stable walking.

Four Way Hacksaw
This machine is built on a rigid steel frame consisting of four hacksaw blades connected perpendicularly in a horizontal plane. The high torque DC Motor is fixed at the centre of the frame on the same horizontal plane. A number of links, fixtures and movable parts are attached between the motor as well as the blades to convert the rotational motion of the motor shaft to reciprocating motion of the cutting blades. It is an industrially ready to use machine with efficient and long term usage capability. .

Four wheel steering
Ask For Availability :- https://bit.ly/32rNhKS
As all the 4 wheels can be steered in this system, the result is that Inside wheel turns at a smaller radius, hence the inside wheel turns at a steeper angle then the outside wheel. The intention is to avoid the tyres to slip sideways when following the path around a curve. Thus the vehicle can be controlled more effectively especially during cornering and parking. Also, this system does not affect the overall speed of the vehicle.
