We’re beginning to think the “S” in [Jeremy S Cook] stands for strandbeest. He’ll be the talk of the 4th of July picnic once he brings out his latest build—a weaponized, remote-controlled strandbeest ...

Using the TDA7052A audio amplifier to generate a five octave, linear in pitch voltage-controlled oscillator (VCO).

If you've never heard of a 'DAC' before, you might be surprised to hear that you most likely use one everyday. DAC stands for digital-to-analogue converter and any device that delivers digital sound – ...

Today in power electronics, the folks over at Texas Instruments have put together a video covering low-dropout (LDO) linear regulators. For a hacker, power is pretty fundamental, so it behooves us ...

This project is implementing core functions of a basic single-phase line-interactive UPS using Arduino. The main idea is to have a fully functional controller, which can manage display indication, ...

This IoT-enabled system continuously tracks a bedridden patient’s vital signs (ECG waveform, heart rate, and body temperature) from anywhere in the world. By combining a microcontroller (Arduino) with ...

Abstract: Wearable electromyography (EMG), electroencephalography (EEG), and electrocardiography (ECG) systems offer a cost-effective means to access one’s heart, muscle, and brain activities through ...
