Coreduino

Coreduino is another clon of amazing Arduino board. Main advantage of Coreduino is compact size, minimized price and easy connection to a breadboard. If somebody don't know what Arduino is please visit website www.arduino.cc for more information, because Coreduino is based on the Arduino concept. In this post you can find information about Coreduino module, USB and Serial programmers for Coreduino.

Simple Serial Programmer for AVR

This is a very simple and easy to build programmer for Atmel microcontrollers from AVR family. The microcontrollers must support serial programming. This programmer is connected to a PC through the RS232 serial interface and can be used with the PonyProg or Avrdude software programmer.

Make a Sound Card with PCM2702

Make a sound card is no more a complex issue. If you use great IC PCM2702 from BURR BROWN / Texas Instruments you can create a fully functional USB sound card. This sound card can be powered from USB port and has one stereo output. You don’t need to install any driver for Windows XP and Vista, because they are already inside. This is really plug and play.

ATmega48/88/168 Development Board

This is versatile development board for AVR microcontrollers ATmega48/88/168. It is good for testing and debugging embedded programs. It has many built-in peripheries connected to microcontroller so you can use them without soldering. ATmega microcontrollers are produced by ATMEL and they include a lot of features: I/O, Timers, PWM generators, ADC, RS232, TWI, SPI, Analog Comparator, Oscillator, EEPROM… These microcontrollers are very versatile, easy to program and easy to use. This is the reason why I like these microcontrollers and why I decided to make development board for them.

CMoy

CMoy is very simple portable headphone amplifier. The amplifier was originally posted by Chu Moy on headwize.com. The best source of information about this amplifier is article How to Build the CMoy Pocket Amplifier. If you use Google, you will find many pages and pictures about CMoy. Few months ago I decided built this amplifier also. In my post you can find my experience with creating this simple but very good amplifier.
