Laser Diode Driver project will help you safely drive (constant current) a 3 mW visible Laser Diode for your application. Input supply - 2.5 to 6 VDC Onboard preset to adjust the current flow to the Laser Diode Power-On LED indicator Header connector for easy input supply...

Sine wave Generator project will provide you with a Sinusoidal Waveform output to test various instruments.  You can also use the High quality output from this kit to insert a tone modulation in your audio and RF equipment.  This kit is designed using XR2206 IC to provide High...

Opto-Isolated 4-Channel Triac Board (R) is used for fast switching applications.  Ideal for switching mains circuits, lights, appliances and small load.  Each circuit is effectively isolated with opto-isolators on each channel, TTL inputs control each channel. Trigger input 2-12...

  Atmega8 Development Board provides a very simple and cost effective platform for prototyping solution.  The compact design provides connection to all the pins of the microcontroller for the user. Prototyping solution available for 28-pin ATmega series AVR...

I started playing with electronics back when I was 10 years old in Argentina, where I grew up. Then I got my ham radio operator license when I was 16 years old and I was very active in the ham club and on the air. It was then when I built my first vacuum tube transmitter and refurbished...

89C2051 Development Stick kit offers an easy way of interfacing 89C2051 compatible MCU's. Slim design with plug in type approach Voltage regulator on board for stable and regulated supply to the MCU RESET switch for resetting the MCU 0592 MHz Crystal 4K external...

This simple A2D (Analog to Digital) Converter Board can log upto 8 channel of analog signal with 8 bit resolution.  This board uses the  ADC0808 chip from National Semiconductor. Two standard box type header connector for easy connection of the board to various development...

This project is not completely new. In fact, the oscillator is made from the same schematic as in one of my previous projects and only the frequency counter is made with different schematic. After I finished the oscillator, I made some minor changes in the square signal part of the...
