Circuit Exchange International

There are ten categories of schematics, a unified circuit analysis, design and theory page, and also a practical electronic section. The simulation section features the "TINA" and "Circuit Maker" programs. (this is a first generation website )

Circuit Exchange International

Some interesting sections are Alarms & Security Circuits, Control & Interfacing, Radio Circuits, Power Supplies & Circuits, Timing Circuits.

Circuit Exchange International

First created back in March 1999 and intended for electronics hobbyists, engineers and enthusiasts everywhere. Currently there are 310 schematics divided into 11 categories. Also included are tutorials, design and simulation sections.  - Andy Collinson

Editing objects performed by interaction with a device touch screen. You can create and edit such graphic objects as: - Point, Line, Polyline, Bezier curve, Arc, Ellipse and Rectangle.

Educational Function Generator Demo

This app from keuwlsoft puts a waveform on the audio output at 44.1 kHz and with a resolution of 16-bit. Two separate waveforms can be output to the left and right audio output channels respectively.

Dual channel function/waveform/signal generator for the speaker/headphone audio output. Educational use, for critical applications use a real calibrated function generator.

K1001 - 8 Channel Serial Servo Controller, Assembled & Tested

Ozitronics - Electronic Kits

K1001 is an 8-Channel Serial Servo Controller based on the Atmel 89C2051 microcontroller. It accepts RS232 or TTL serial data from a computer or microcontroller and outputs PWM (pulse width modulated) signals to control up to eight RC servo motors (as used in radio-controlled model airplanes, cars, etc.).

Unused servo pins can be reconfigured for digital output to drive on/off devices.
Up to four controllers can be multi-dropped on a single serial port for controlling up to 32 servo motors - more on request.
