Circuit Lake

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.

This PIC18F1320-based mood lamp project contains of 3 Luxeon Star LED lights, red, green and blue. Each light uses around 1 Watt maximum. It typically consumes 40-60 times less electricity than a standard incandescent light bulb, It’s very efficient in energy use.

This PIC16F876A-based accu cycler project allow you to charge and discharge NiCd and NiMH accumulators for R/C modelers and others. It has performance close to commercial products in the market. The ‘intelligent’ part of the system can communicates with PC using serial port providing additional process visualization.

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 in [...]

The project is an electronic version of an Etch-A-Sketch toy for kids. It can electronically emulate every function of the original. The system use Hyundai HG225504 LCD as screen which displays 256 pixels wide and 128 pixels high. Instead of a complex mechanical rail and pulley system to control the X and Y movement, Etch-A(vr)-Sketch [...]

This AVR Atmega16-based rocket controller is designed to be used in water rockets (or any other type of rocket for that matter). The rocket controller allows the rocket’s performance to be logged (altitude, accelerations), and provides control of the parachute deployment system. Altitude is measured using a pressure sensor device. While acceleration is measured using [...]

This accurate clock project is developed based on the GPS Receiver which captures a time signal from the U.S. government’s global positioning system (GPS) satellites and parses it to extract time syntaxes from NMEA string to finally display on 7-segment displays. The transmitter on GPS clock then broadcasts the time to every other nearby wireless [...]
