Those who have children of their own might argue that the youth of today are getting far too much internet time. [Nick] decided to put an emergency stop to it and made this ingenious internet kill switch to threaten teenagers with. Rather unassuming on the outside, the big red button instantly kills all network traffic as […]

From building your own analog effects pedal to processing audio through micro controllers, a lot of musicians love building their own boxes of sound modification. In his entry for the 2019 Hackaday Prize, [Craig Hissett] has a project to build an all-in-one multi-effects stomp box. At the center of the box is a Raspberry Pi with

Rotary dial phones have a certain romantic charm about them; something never quite captured in the post-Touch Tone era. With landline phone services less popular than ever, these old workhorses aren’t really cut out for daily use anymore. However, with a modern brain transplant, they can still get the job done just fine. [Xabier Zubizarreta] has

Does the world need another connected thermostat? When my thermostat went on the blink last winter, I looked at Nest, and Ecobee, and the other me-too thermostats, and I decided I would rather build my own. If Nest goes out of business (or even more likely, Google decides to go a different direction), all that

Working with microcontrollers means managing GPIO pins at some point. Many configurations have been developed for modern microcontrollers which can lead to some “fancy” terms that may confuse programmers. Its important to understand all of this to avoid confusion and errors while programming. First, some terms need to be understood. GPIO pins have tri-state logic

Introduction Frequency domain analysis is very important to know more about any system/ circuit or transfer function that we deal with. And the first thought comes to our mind about frequency domain analysis is “Bode plot“. Bode plot is a combination plot of magnitude and phase difference of output vs. input of a cosine wave

Artificial intelligence (AI) is an area of computer science that works towards creating machines that could make decisions, react, and interact just like a human would. To be considered AI a computer must be capable of recognizing speech, learn, plan, and solve problems. To do all this a computer must have a way to perceive
