[Janis Alnis] wanted to build an analog computer circuit and bought some multiplier chips. The first attempt used apparently fake chips that were prone to overheating. He was able to …read more Continue reading Lorenz Attractor Analog Computer with Octave Simulation
Certain among our readership will no doubt remember attaching a playing card to the front fork of one’s bicycle so that the spokes flapped the card as the wheel rotated. …read more Continue reading This Found-Sound Organ Was Made with Python and a Laser Cutter
While [MicroKits]’ MicroSynth is an all-analog synthesizer that fits on a business card-sized PCB, and he actually does use it to break the ice in business meetings, that’s not really …read more Continue reading MicroSynth Mixes All-Analog Fun with a Little Business
[Ted] recently demonstrated the analysis of an RL circuit using a piece of paper, Octave, and LTSpice. If you prefer, the Octave code should work fine in MATLAB, as well. …read more Continue reading Phasors in LTSpice
If you’ve taken any digital signal processing classes at a college or university, you’ve probably been exposed to MATLAB. However, if you want to do your own work, you might think about Linux and one of the many scientific computing applications available for it.
[David Duarte] recently published a three-part tutorial on using Octave to do scientific audio processing. The first part covers basic reading, writing, and playing of audio files. Part two covers synthesis of signals, plotting, and some basic transformations. Modulation is the topic of the third part. If you prefer your tutorials on video, you can check …read more
