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 [...]

Besides voltmeter, sometimes we need oscilloscope to analyze signal from our electronic project. Unfortunately, the price for good digital Oscilloscope is expensive. For student and electronics hobbyist there are good solution for this. You can try Free PC based Oscilloscope like Visual Analyser. The software can be used to analyze waveform with range frequency [...]

This java based circuit simulator is useful application for electronic student and hobbyist to learn electronic circuit You can simulate basic circuit like RLC circuit, Digital Logic Circuit, Opa-amp, MosFet, Passive Circuit, or combination analog digital circuit in animated schematic.

If you need tools to log and analyze your USB project then Virtual USB Analyzer might help you. It is a free and open source tool for visualizing logs of USB packets, from hardware or software USB sniffer tools. The tool provide a graphical visualization along with raw hex dumps and high-level protocol analysis.

Electronics Assistant is a mini freeware program that performs electronics-related calculations like resistor color code calculator, resistance, capacitance, power calculations, inductance, frequency calculation and more. The software run under Windows OS. You can print or save of calculations detail. This tool built by Simon carter to help beginner in electronics or hobbyist who need quick [...]

First step to build your electronic project is getting some reference and start draw your project schematic. You can use Eagle software (Free Version) to draw schematic and create PCB. But Eagle Light edition limited to 100 x 80 mm (4 x 3.2 inches) area and only Top and Bottom wire (2 sides PCB) and [...]
