Brainwaves Correct Robot Mistakes in Real Time—with a Little Help from Machine Learning

Brainwaves Correct Robot Mistakes in Real Time—with a Little Help from Machine Learning

The idea of controlling robotic operations with nothing more than brainwaves is the ultimate expression of the man-machine interface. The introduction of machine learning to detect actionable brainwave signatures—and translate them into commands a robot or other actuator can comprehend—opens up new and potentially unlimited vistas into possibilities for revolutionizing...

A World of Free Energy

A World of Free Energy

Energy harvesting is the process of collecting of energy from an array of environmental sources, both natural and artificial, most of which is otherwise wasted. These myriad forms of energy include any of those sources through which we can extract electrical current to power any number of low-power devices. The...

Radio Frequency Modulation Made Easy

Radio Frequency Modulation Made Easy

Modulation is a technique that changes the characteristics of the carrier frequency in accordance to the input signal .  Figure 1.1 shows the conceptual block diagram of a modern wireless communication system. As shown in the figure, modulation is performed at the transmit side and demodulation is performed at...

An Arduino-based Brain-Computer Interface

An Arduino-based Brain-Computer Interface

Whenever you think a thought—and even when you don’t—the more than one hundred billion neurons making up your brain fire through and across an interconnected web of terminals in an elegant electronic interplay. And at just that moment when the sum of input signals into one neuron crosses a certain...

Getting Started with Arduino

Getting Started with Arduino

Perhaps the two most popular microcontroller-based systems right now are those based on the Arduino and the Raspberry Pi (RP). While both have huge followings, they are not the same type of microcontroller. The RP is a complete small computer system with most the common add-on features like a keyboard...
