This Logic Analyzer project allow you to monitors and captures a number of digital signals. It uses PC to display the data processing. The system consists of ATmega88-20PU AVR microcontroller as main processor and some simple components used for the interfacing with the PC, the man and the probes.
The Hibox is High DC Power Meter based on the Atmel Atmega16 microcontroller. This equipment is capable to measure DC voltage up to 40V, currents up to 200A (600A with special sensor) and shows all values on 2×16 characters display. It was developed for enhanced measurements on new Lion/Lipol batteries which are widely used [...]
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 [...]
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 20-20khz. [...]
The project uses Direct Digital Synthesis to generate sine, triangular and square waves in the range of 1 Hz to 150 KHz with 1Hz resolution. The frequency can be set through 16 switch numeric keypad or rotary shaft encoder (fine adjustment) and is displayed on a backlight numeric LCD module, Varitronix LCD module VIM-808. For [...]
AVR-Doper is an STK500 compatible In System Programmer (ISP) and High Voltage Serial Programmer (HVSP). It comes with a built-in USB to Serial adaptor to connect to modern host computers which often don’t have a serial interface. The project implements a low speed USB device in firmware only. No USB capable controller or converter is [...]
