Circuit Lake

The project shows you how to build PIC-based emergency power system for 12-Volt device system. The hearts of the project is PIC16F870. The system will monitoring battery voltage both charging and discharging currents, control 4 digit display, and switches the AC and load relays.

This ATmega64 microcontroller based Wireless Rocket Launch Control system is cost-effective and safe solution for better rocket Launch Control Officer. It solves all of the problems with typical old launch control systems that only use combination of batteries, wires, switches, and relays. There are two main part in the system: the launch console where [...]

The PSK31 (Phase Shift Keying, 31 Baud) Adapter is a hardware interface between a PC running a digital communications program, such as DigiPan, and an Amateur Radio transceiver. The electronically adjustable PSK31 interface is controlled by microcontroller AVR ATmega8. It provides automated adjustment and optimization of the audio levels that are carried between the [...]

The Multi-saw Edger Controller is used to accurately position circular saws for cutting timber in widths varying from 50 mm to 350 mm or more. The project have three saws on a shaft, with Saw 1 being fixed to the shaft and Saws 2 and 3 sliding along the shaft with bi-directional hydraulic actuators.

This project shows you how to implementing your own Web/WAP enabled home automation system. It will allows you to control the on/off state of up to eight 3A appliances via either a web browser or a mobile phone.

If you need electronic simulator with the ability to set the speed of the rotation, and start and stop on demand as in the actual system then check out this Encoder Simulator. The project very useful for troubleshooting or developing new programs for control systems when there is unavailability of the target system for experiment, [...]

This four channel pulse width modulation (PWM) controller is built around Atmel ATMega16L. It has RS232 serial interface for computer control, four 10 bit analog inputs and a 12-button keypad interface. The controller also has four indicator outputs (which may be configured as general purpose outputs), an alphanumeric LCD interface (with backlight control), three general [...]
