I was recently mulling on FPGA implementations of short length Fast Fourier Transforms (roughly N=30 to 100) at work. My dilemma was I needed a potentially arbitrary number of these in a scalable ...

Multimode fibers (MMFs) are gaining renewed interest for nonlinear effects due to their high-dimensional spatiotemporal nonlinear dynamics and scalability for high power. High-brightness MMF sources ...

This page is focused on how you can send different signals on the GPIO pins of the Flipper Zero. The timing of the signal you need to send will depend on the hardware attached. For example, a LED can ...

Pulse-width modulation (PWM) is a technique for changing the amplitude of digital signals to control devices and applications that require power or electricity. It effectively regulates the amount of ...

Recent advances in deep learning have been providing non-intuitive solutions to various inverse problems in optics. At the intersection of machine learning and optics, diffractive networks merge ...

This tutorial is a part of series of MSP430G2 LaunchPad tutorials in which we are learning to use the MSP430G2 LaunchPad from Texas Instruments. So far we have learnt the basics of the board and have ...

The creative adventures with ATtiny series microcontroller are awesome if you know how to play them. ATtinys — especially the ATtiny85s — are all around us, and by using one, we can shrink the size of ...

Joe is a graduate in Computer Science from the University of Lincoln, UK. He's a professional software developer, and when he's not flying drones or writing music, he can often be found taking photos ...

Abstract: Low-density parity-check (LDPC) codes have attracted much attention over the past two decades since they can asymptotically approach the Shannon capacity in a variety of data transmission ...

There has been poor documentation online about using i2s on a RaspberryPi and in particular connecting a MEMs microphone. There is plenty of discussion but no clear tutorial and/or explaination. These ...

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...
