PC sound cards form a readily available Signal Generator for testing electronic circuits. The utility of these signal generators is limited because the outputs are AC coupled and limited to ±2V. Taking advantage of the two channels provided by the sound card this Instructable shows a scheme which uses one channel to output the Sin/Square/Triangle […]
Hi, today I’ll explain how to make your own little Weather based Music generator. It’s based on an ESP8266, which is kind of like an Arduino, and it responds to temperature, rain and light intensity. Don’t expect it to make entire songs or chord progressions. It’s more like Generative Music people sometimes make with Modular

The oscillators are the devices that generate oscillatory (AC) output from given DC input. There are different kinds of oscillators based on the output waveform they generate. Like · Sinusoidal oscillators – they generate sinusoidal (sine) wave output · Square wave oscillators – they generate square (or rectangular) wave output · Triangular
Intro Back when I was deverloping the PSU burner, I wanted to have the Analog Discovery isolated from the common ground, to avoid noise and other issues. Since I did not have a way to do this, I ended up using a laptop on battery for measurements. But for long term, I needed to have
A signal generator is an electronic device that generates electronic signals and waveforms. These electronic signals are either repeating or non-repeating as per the requirements and field of applications. It is generally used in designing, testing, troubleshooting and repairing electronic devices. A signal generator can generate various kinds of waveforms. Most common are the sine
Infinite Noise TRNG (True Random Number Generator) For instructions for compiling the and using Infinite Noise TRNG driver, go to the software sub-directory, and read the README file there. Both Linux and Windows are supported. The Infinite Noise TRNG is a USB key hardware true random number generator. It uses what I call a “Modular
