My Story | Founder of Proto21 3D Printing LLC
The journey started when I was awarded an exchange semester scholarship to University of Alabama, Huntsville, USA during my bachelors of engineering in Pakistan. It was Spring Semester of the year 2012. As part of scholarship we were asked to take courses and engage our selves in the university events and activities. Being a tech…
Hacking a Servo to Spin Continuous Rotation
Demonstration: What is a Servo? A servo is a device comprising of a two wire DC motor, set of gears, a position-sensing device (usually a potentiometer), an integrated circuit and output shaft. Unlike the DC motor, Servo has three wires. One is for power, one is for ground and the third wire is a control…
Basic Programmed Robot
Demonstration This page will lead you to step in to robotics, and show you how to make your First Robot Completely programmed by arduino Believe me, making robot with arduino is really a piece of cake only if once you have a complete understanding of things… I just tried to make it as simple as possible, and show…
Servo Speed Tester
Demonstration This is probably the simplest Circuit to test a Servo, This circuit tests the speed of servo. Here we use potentiometer to controll the speed of the servo. By applying very less voltage like 4.5V and reducing the pot value, you can also adjust the position of the servo! Check this Circuit which uses…
Starter Kit for Electronics
To get started you must have your own stuff, it will cost a little but that’s the only way to learn Electronics :p well I bet you it wont exceed 1500 rupees. In Hyderabad you can get most of the stuff but I will prefer you to buy it from Karachi, because it will be way…
Intro to Fritzing
Fritzing is an open-source wonderful software for artists, researchers and hobbyists to work creatively with interactive Electronics. It is developed at the University of Applied Sciences of Postdam, Germany. It is widely used in order to convert the Circuit Diagram into PCB layout to get a actual product out of it. It also has interactive and…
Simple DC Generator
Demonstration This little project is one which I made when I was in grade 7 in High School, and I won a prize on this. May be the judge liked the concept behind it. One my friend asked me how to “Convert Mechanical Energy into Electrical Energy”. First thing which came into my mind was Wind…
Resistor Color Code
Demonstration function calc() { var ans = parseInt(document.getElementById(‘txt1’).value); if( ans >= 1000000000 ) { ans = ans +””; var result = ans.substring(0,4); document.getElementById(‘txt1’).value = result+”M”; } else if( ans >= 100000000 ) { ans = ans +””; var result = ans.substring(0,3); document.getElementById(‘txt1’).value = result+”M”; } else if( ans >= 10000000 ) { ans = ans…
The Art of the Brick
I visited Zurich, Switzerland to my friends. They planned my trip to various places and one of them was the “The Art of the Brick” exhibition. Usually I am not an exhibition person, but when I heard that the exhibition was about an artist who shows his artistic skills with LEGO. I was sure that…
