Magnetic Stirrer Making

Magnetic stirrer is a mixing device which is commonly used in laboratories. For mixing different types of liquid samples.It consist on rotating magnet that creat rotating(adjustable) magnatic field to move stirring bar or spin bar(cylindrical magnet having narth pole and south pole) in soloution. The movement of this bar mix soloution very quickly. The speed of stirring is controlled by the user according to specific sample that's being stirred.Use glass beaker to prevent the interference of magnatic field.

The making procedure of this device is very simple ,you can make easily at home by following few easy steps.
● design body structure of device. we use wooden boards to build of device.

●Use silver plate in the stirring area to prevent the interference of magnetic field.

●To conteol the speed of stirring  we use PWM speed controller(dc motor speed controller)

●To create rotation magnatic field attach a piece of magnet on the one side of wooden bar.
●Connect the wooden bar to dc motor.

●Connect the Dc motor middle of stirring area. 

Components 

•Dc Motor.

•Piece of Magnet.

•Silver plate.

•pieces of wooden board.

•Dc motor speed controller. 

•9v dc Adopter.

•Magnetic stirrer bar.

•some connecting wires

DC motor speed controller PWM making

There are many ways control Dc motor speed.Pulse Width Modulation (PWM) is very basic and common way to control DC motor speed.

we are going to make Pulse Width Modulation(PWM) circuit. Many others ways to make PWM circuit,But we design PWM circuit with the help of 555 timer ic.

The accuracy and durability of the circuit is very good. 

following components are use in the designing of PWM.
●555 Timer IC.
●IC socket(optional).
●Potentometer 100k.
●IRFZ46N.
●Regulator Heat sink(optional).
●Capistors (2)104.  (1)103.
●Diodes (2).
●Resistance 10 kilo ohm.
●plastic circuit board.
Design the circuit according to the circuit diagram.

Sold all components carefully.
use soldring station for best soldring.

Electric fan heater making

 

Electric heater is a need of everyone in winter season. Many kinds of electric heaters use for heating purposes.Today we are going to make a portable electric room heater with low cast and very low consumption of electricity (600w).This heater consists on tow powerful fans, which increase temperature of your room very instantly.

This is designed in very compact size, it adjusts everywhere easily.
making process is very easy and very simple.
you can make in very short time by following few easy steps.

●design body with wooden board (10"×5")inch.
●fix heating rod and fan into body.

●connect wires carefully according to circuit diagram. 

components

•2 hearing rod.

•2 fan.

•2 power switch.

•some connection wires. 

•wooden pieces (10"×5"),(5"×4").

•12 v Dc Adapter.

Zero watt LED bulb manufacturing

 

0 watt bulb commonly used as night lamp and decoration  purposes . It's low intensity bulb. The electromagnetic meter could not measure power of such a less magnitude. The older meter read ‘zero’ power, and hence the name of bulb is zero watt bulb.Zero watt bulb used in many colours. 

Today we going to make 0 watt bulb by following few easy steps, with low cost and in very short time.

●we use Led bulb case. 

●The following components are used in designing of bulb.
●Pice of plastic circuit board(PCB).
●4 LED bulbs (we use red, green, blue and yellow).
●184J capistor
●1.5 and 100 kilo ohm resistance
•Design the circuit according to the circuit diagram on circuit board. 

•Sold the components carefully.

Fix your mobile charger problems

 

when your charger doesn't charge your phone's, then what to do.

Today we going to introduce some tips and tricks to fix your problems easily by following few easy steps at home.

●Frist of all make sure your charging jack is in working condition.
●Then move to your charging cable. If some wires make-break the connection,then replace charging cable.
●If both are in working condition, open charger case and detect the damage component(may be it's burn or explode) in circuit.
Mostly resistance, diode and capistor are damage.
●Replace carefully the damage component with nearly same values.

Logo printing on physical objects

If you want to print your logo/photo professionally on Physical objects you need some printing machines. but we are going to print logo on physical objects at home, by following few easy steps. With the help of paints. For printing that types of logos or photos you need hard copy of your logo, scotch tape and gum stick. By following this way you printing your logo on every type of surface.

step1. Eliminate required surface from hard copy of your logo(color wise).

step 2. Paste the paper on physical object with the the help of adhesive materials. 

step 3. Apply paints as your required color.

Soldering station

Soldering station/third hand or helping hand is a device which is used for electronic components soldering.This type of devices mostly used in electronic and electrical engineering labs.The device consists on circuit board holder/electronic components holder, Magnifying glass and lamp.

●The circuit board holder/components holder works as helping hand, commonly it consists on tow moveable jaws .
●Magnifying glass is helpful for  Magnifying the small components during soldering.
●Lamp is use for illumination on soldring place.
