PRO E TUTORIAL DESIGN OF PISTON

In this video i am gonna show you how to design a piston in pro e.IN another video i will show you the connecting rod with piston.
Revolve,extrude are the different 3D commands used in making this.

WALKING ROBOT USING SERVO MOTORS


I am making some projects with ATMEL AT89S52 and decided to create something that would fully use its potential. Then came the idea to construct a robot that would be able to  walk like a human. It was all realy simple in my head, create a skeleton with the same movement passibilites as a human and then write a program that would make it do the right moves.

 It seems simple but as it turned out there are a lot of things to calculate and take into consideration.

WALKING ROBOT USING ARDUINO

Building a simple walking robot is really easy. Don't let the number of steps fool you into believing otherwise. This robot is basically made with a handful of household items and some simple electronics that you can easily pick up at Radioshack.
In fact, this robot is entirely zip tied together, which makes building it and modding it extremely easy.

KEY CODE LOCK SWITCH


This key code switch circuit is a type of electronic circuit that is created to replace conventional normal key switch. Without inserts a keys.But you can press the number code instead of unlock keys.
 We do not have to carry a load key and do not worry about your keys are lost. We just must remember to commit to a code only.

KNIGHT RIDER PROJECTS USING 555 AND 4017 IC

This circuit mimics the lights in knight rider's car. They flash one at a time chasing each other. In the Knight Rider circuit, the 555 is wired as an oscillator (Astable mode).
The output of the 555 is directly connected to the input of a 4017 decade counter.

MOBILE PHONE DETECTOR

This is a mobile phone sniffer circuit that can detect the signals being used in the GSM (Global System for Mobile Communication) band at about 900 MHz.Since the signals are digitally encoded, it can detect only the signal activity, not the speech or the message contents.

CLAP SWITCH USING 555 IC


In order to make a clap switch, we have to combine the  touch sensor(monostable mode of 555 and the transistorized dark sensor circuits. Whenever there is loud sound produced near the electret condenser mic, pin 2 of 555 gets triggered and it switches on the LED D1.

LINE FOLLOWING ROBOT USING 555 IC'S


This is Simple and cheap approach to Line Following Robot, This do not have any micro controller but just a simple basic Circuit on three 555 timers. It has a good efficiency on following all kind of curves. 
This Robot is no more than 1000PKR. To make a reliable and well functioning robot, you just not need Electronics Skills but also a little Mechanical too.

MOBILE CONTROLLED ROBOT USING GSM TECHNOLOGY

Controlling a robot wirelessly is possible with several methods such as Remote, Bluetooth, Wi-Fi, etc. But, the controls of these communication methods are limited to certain areas, and complicated to design as well.
To overcome these difficulties, we have come up with a Mobile Controlled Robot.

LM386 LOW VOLTAGE AUDIO AMPLIFIER


Suppose there is a set of 4 ohm speakers(large).
if we connect them to mobile or mp3 player,the output will be very less ie., very less sound is obtained.In order to rectify that an amplifier plays a major role.so lets make a low voltage audio amplifier.

LINE FOLLOWING ROBOT


The sensor module has two LED-LDR sensor pair mounted on it (Minimum two is required. You can use any number). The LED or light emitting diode is a semiconductor light source which we will be using. I had used a 5mm white LED for my project. Also, LDR or Light dependent resistor is used here as a Light sensor.

SOLAR MOBILE CHARGER

I am going to show you how to make a solar USB charger from old garden lights. 

With that charger you can charge every device that uses the USB port to charge like : (mp 3 player, i phone,psp's etc.)
(In my solar charger i put some led's to be able to use it as a torch)
