This article describes a versatile Raspberry Pi RP2040–based signal generator that can be operated from a PC through an RS-232 interface. Requiring only minimal, low-cost hardware, it is capable of ...

As we (or maybe just I) stumble bleary-eyed into 2026, I want to take a moment to look back at the notable features, changes and innovations Ubuntu saw in 2025. Because it was, as ever, quite the year ...

Discover how a Raspberry Pi, a DDS module, and an ADC come together to form a powerful DIY RF sweep generator for RF testing. This compact setup lets you generate frequency sweeps and visualize ...

Arduino library for parsing and decoding MOD, WAV, MP3, FLAC, MIDI, AAC, and RTTL files and playing them on an I2S DAC or even using a software-simulated delta-sigma DAC with dynamic 32x-128x ...

I built a Raspberry Pi FM transmitter using only software without any external RF modules or transmitter HATs. Let me explain step-by-step. The Raspberry Pi, a versatile single-board computer, can be ...

A waveform generator is a commonly used test and measurement instrument in electronics laboratories. Waveforms of different functions, frequencies, and amplitude levels are often required to test the ...

So you have a need for a USB Oscilloscope? Maybe you are a Maker or enjoy tinkering with old electronics and would like your shiny PC to be able to help you out. One thing is for sure, while certainly ...
