Differential Amplifier
This is the last article in the series of differential op-amp circuits. This is one of the most important operational amplifier circuits and hence it was saved for the last. The speciality of using differential amplifier is that it uses both inverting and non-inverting input terminal to amplify one input signal, while other is fastened to ground Let me remind you that the output is equal to the difference of the input, and as said...
HitchBot – The Wikipedia-Reading Robot
HitchBot, a free-spirited robot is ready to explore Canada to meet new friends on the go. It is developed at Port Credit, Ontario by Dr. David Smith of McMaster University and Dr. Frauke Zeller of Ryerson University. It is the successor of KulturBot, which is made to travel from one art gallery to other for tweeting artwork photos and venues. The developers are going to put their robot on the side of the road from Halifax to Victoria,...
Processing IDE
Processing is an Integrated Development Environment built in 2001 by Casey Reas and Benjamin Fry. These guys are from MIT (Media Labs), Aesthetics and Computational Group. They were working on something so that something could get non-programmers to start a program. For your information, Arduino language is based on Processing IDE, and is very much similar to the Arduino IDE. Processing IDE is based on Java, whereas Arduino IDE is...
Kinect for Robotics
Kinect is a motion sensing input device that was available for military purposes. Now they have decided to make it available for larger masses. Well, the question arises like What is Kinect? Face recognition Depth imaging Gait analysis Skeletonization Actually, the main use of Kinect is to trace out the terrorist hanging around with the general public. We can use it for gestural interfaces using biometrics’ motion capture. Fine,...
The Basic Anti-log Amplifier
The result we get when the base is raised to the power equal to the logarithm of that number is called anti-logarithm of that number. This particular setup can be formed by connecting the transistor or diode as the input element in contrary to logarithmic amplifier. The exponential formula still applies to base emitter PN junction. The circuit for the anti-logarithmic amplifier is as shown below: ANTI-LOGARITHMIC AMPLIFIER USING BJT...
