LCD Smartie is software for Windows that you can use to show lots of different types of information on your LCD/VFD. It supports LCD/VFD’s with a Hitachi HD44780 Controller, a Matrix Orbital Serial/USB LCD, Crystalfontz Serial/USB LCD, Seetron Serial LCD/VFD, IRTrans driven VFDs, SoundGraph iMON VFDs, Futaba VFDs, Pertelian LCDs, VL System L.I.S VFDs, [...]

Xoscillo is free oscilloscope software that acquires data using an arduino (with custom firmware) or a Parallax USB Oscilloscope. Aguaviva is developing this project to support more platform.

This C#-based application features frequency analysis using FFT, auto detects the hardware, load and save waveforms, zoom in and out, open several waveforms at the same time, [...]

The Soundcard Oscilloscope is useful electronics software for student and electronics hobbyist. Like visual analyzer, the software use PC Soundcard as main hardware. The software receives its data from the Soundcard with 44.1kHz and 16 Bit resolution.

To get non-standard resistor value we can use parallel or series resistor combination. You can do quick calculation for R series but, sometimes, it’s hard to get good resistance combination in parallel resistor to get R value that we need. Thanks to Claudio Girardi who has built Resistor Series-Parallel Calculator. It will help you find [...]
