Built your own portable mobile charger with simple circuit.....

Components required:

     1. LM7805(voltage regulator)

     2.Bread board or PCB

     3.Connecting wires

     4.Solder and soldering paste if in PCB

     5.9V battery

     6.Battery snip

     7. Usb


Procedure:

Step 1: Select the components required

Step 2: Now place 7805 IC into the board

Step 3: Now make power supply of 9v into input pin

Step 4: Now ground the middle pin into 9v battery

Step 5: Then connect the out pin into mobile usb cable

Step 6: Connect with insulating tape

Step 7: Connect your mobile with usb pin

Step 8: It is now charging

Step 9: Watch below video..

Wired Remote controlled car simple step by step construction

Apparatus required:

1- Connecting Wires,

2- Jumper Wire,

3- Rocker Switch,

4- DC Motor,

5- Wheels,

6- Chassis,

7- Power sources,

8- Box,

9- Insulating tape,

10- Soldering tools.

Construction:

Buy the required simple apparatus to start making robot.

Take the Rocker switch in the hand and connect the pins in X model.
To control the car in both direction.  Then place the switch in the box slot to make that as a remote.

Make power supply to the switches in the box. Now connect the jumper wires in to that and connect that with DC motor too.

After completing the connections try to work out with that.

Watch this video and get step by step construction of Robot.

Working:

We can use this car in many small projects. Watch this video to see how it is working.

Autocad basic commands to configure drawing sheet

     Autocad is the commonly using designing software on all Mechanical Industries.  It is the tool used to draft on computer.  This is the word CAD forms Computer Aided Designing

Now Autocad offering Autodesk software Free for students and educators.

 visit my other post First step to Autocad

Now Start Basics:

• On using Autocad after opening the software drawing page,  We need to configure our drawing sheet.
• On first step configure our page limits
• Page limit for A3 sheet is (0,0) & (420,297)
• By using LIMITS command we can do that.
• Now we need to configure the units of drawing sheet
• To do that use UNITS command make units Millimeter and Precision at 0
• Then do on dimension style which you need from DIMENSION on task bar then click on Dimension style
• Watch the below video too to learn by visual.

First step to Autocad

     This is the first article of my AutoCAD tutorial. Since I have made tutorials for robotics beginners, then I think, why not I can writing AutoCAD for beginners too? I know that there are many resources like Books, Internet  for learning AutoCAD, but I hope this is still useful.

About Autocad:

     Autocad is the tool used to draft on computer.  That is the word CAD forms Computer Aided Designing.  Implementing of the CAD is known as CAM.  That is Computer Aided Drafting.

     On most of the manufacturing companies/industries are concentrated on CAD to design their equipments from Computer and then make a real time object by using other mechanical devices.  Now we see how to use CAD.

Step 1:

• On AutoCAD drawing area. This is where we will drawing our AutoCAD objects.
• AutoCAD Ribbon. This is where we can access AutoCAD tools and settings.
• AutoCAD Ribbon has several tabs. Each tab holds AutoCAD tools based on our drawing task. For example, we can use drawing tools and modify tools in home tab. But when we need to add text and dimensions, we need to open the Annotate tab. When we need to insert blocks, we need to move to insert tab.
• In each tab have several panels. This panels have similar AutoCAD tools inside them.
• Command Line. We can activate tools and change the tool settings by typing in command line. Command line is also providing information what we should do next.
• Drafting Settings. While we draw, we need to change some drafting settings. This is where we can change it.
• The AutoCAD logo. Click it once (do not click it twice, as doing it will end your AutoCAD session).
• AutoCAD will show you the AutoCAD menu.This is where we can access tools related to applications, such as saving files.
