Simple four wheel Robot control circuit on 12V Power supply

This circuit Works for  four 12 volt dc motors .In this cricket.  I gave the two output  terminal for both left and right motors.

For that we have to connect both left motors in parallel and both right motors in parallel.

As shown in fig. S2 and S1 switch is DPDT Rocker type switch .connection is same for left and right so I gave only right one connection. We have to connect parallel connection of right side motors between pin no.6 and pin no.4. of switch. Switch 1 is used for on off for power supply And using the variable resistor you can change the speed of motors.

NOTE: Use sufficiently large het sink else it will burns the transistor .

Here is the view of DPDT Rocker switch with pin number .use this pin number  to further connections

Flowing Diagram shows. How to connect the pins of switch to each other.

Now we have to place this switches side by side on solid surface(right switch at right side and left one is at left side)

HOW IT WILL WORK?

1] When switches are ideal no motion is done..

2] When we press both switches up or forward robot go forward.

3] When we press both at switches or backward robot go backward.

4] But when we have to turn robot towards left side .We have to press only right side forward switch.  

5]And when we have to turn robot towards right side .We have to press only left  side forward switch.

Hack Google talk for conference voice calling.

HI gays we can make voice conferencing call using g talk

For that we have to make some changes in Google talk shortcut

Here is what we have to do ?

1] Install a Google talk on PC

2] It creates a shortcut on desktop (If not plz make it from installed folder)

3] copy this shortcut  from desktop and again paste on desktop . It will create a new shortcut of name

    “Google talk copy”

                           

4] Now we have to do some editing.  Right click on shortcut of name ” Google talk” go to properties

            

 5] Go to shortcut tab and clear target textbox.

6] And paste [ “C:\Users\KG\AppData\Roaming\Google\Google Talk\googletalk.exe" /nomutex ] in       target box Without taking the square bracket

7] Do same procedure for the “Google talk copy” shortcut also

8] Now what we have done? we create two Google talk shortcuts which works separately

                

           

9] Now we can call one friend from first Google talk and second friend to another one Google talk shortcut

NOTE:-If you want to call more than two friends just again copy and paste already edited shortcut

            (Number of friends = number of shortcuts)

10]Enjoyyyyyyyyyyy

Very simple 3D Glasses in just Rs. 10 using gelatin paper

OK here is simple steps

1] Buy a two  gelatin paper Red and Blue Rs.5 of each  
    you can get it from any stationary shop.
   

2] Now take a Scissor and cut a 3 small pieces(size=size of  glasses)  for red and blue each 

3] Put all red pieces on each other and stick it. do same for the blue also
     
      NOTE:-no. of pieces are depends on the quality of paper.
                  we required special shade.  we change it by 
                  changing the no of pieces on each other.

4] Now take a cover of any note book and cut the 2 shapes as shown in fig. below

                   

5] And put the both bunch of pieces between the 2 cuted notebook cover .

     And stick it.

6] Now make some structure to hold it on your ears  using same notebook paper

           NOTE:-But take care of make red paper on left eye and blue paper on right side

7] Now you are ready to watch 3d images and videos on your pc or laptop

          NOTE:-These glasses work only on when images and video are made for

                       Red and cyan analogy 
8] Try these images from your glasses also you will find the 3d videos on you tube 

Create 3D glasses (Red and cyan)

1. 1
   
   Find a cheap pair of plastic sunglasses. Dollar store or thrift store ones are perfectly fine, or you can find them in the kid's toys section. Pop out the plastic lenses.
   
   
2. 2
   
   Use the plastic lenses as a template to draw the correct shape onto the transparency sheet, cellophane, or acetate.
3. 3
   
   Cut out the lenses on the inside edge of the line you have traced on the plastic.
4. 4
   
   Color with the red and blue markers. If you didn't use red or blue colored plastic sheeting, you'll need to color each lens. Make one lens red, the other blue.
5. 5
   
   Place the colored lenses back into the frames. Red goes on the LEFT, and blue goes on the RIGHT.
6. 6
   
   Check that they fit well. Make any adjustments needed. Then start watching your 3D movie.
