"There are two CPU in our project, ATmega328 and ATmega1284. We set up the wireless communication by two Xbee chips. One of them connects with ATmega328 working as the transmitter to transmit the signal, another one is connected with ATmega1284 to be the receiver. We pick up ATmega328 to be our transmitter part because there is a microphone on it which could receive and store the voice signal from people."

"This easy-to-build electronic device allows you to take a screenshot of your calculator display and show it on an NTSC or PAL television set. Unlike the TI-Presenter this does not require a special calculator or a USB adaptor; it uses the 2.5mm link port."

"With the phasing out of game, serial and parallel ports from modern computers and the ever increasing popularity of USB, it makes sense that hobbyists start getting to grips working with USB….This project focuses on the use of a USB PIC and the mikroC compiler to convert an old game port joystick to utilize USB."

"Another piece of my ongoing FPGA stereo-vision project. This board is, as the name suggests, a breakout board for Aptina’s excellent MT9V032 1/3″ VGA image sensor. The board’s main purpose in life is to connect the LVDS output of the MT9V032 sensor to my FMC-LPC to SATA adapter board, which would then route the LVDS data into one of Xilinx’s Spartan-6 FPGA development boards. Multiple camera boards would be connected to support stereo vision."

"In this project we are going to drive a single unipolar Stepper motor M35SP-8 (5 wire) using USB interface from a PC Computer. This project is an application of the USB Interface circuit PIC18F4550 which was published here in the past."

"An Arduino board can communicate with the Raspberry Pi via a serial over USB connection. This creates a virtual serial interface, which it uses like a normal interface, reading and writing to the serial device file."

"The following page documents the construction of a rather large electric scooter for ‘semi-offroad’ use. My goal was to have something usable to zip over to a train station or grocery store, regardless of it was snowing goblets of ice outside. This project unfolded slowly over the course of ~18 months, in a start-stop fashion, as time became available."
