MP3 Player with SD Memory Card - The MP3stick is a simple and small portable
MP3 player. A microcontroller Atmel AVR ATmega128 is the heart of the circuit. MP3
decoding is done by an VLSI VS1011b decoder IC. A MMC/SD card works as memory medium
for MP3 files, playlist files and skin files. The player is designed to draw his power
from a LiIo/LiPo battery with 3.6V. a charger circuit, based on MAX1811, is included.
All information will be shown on a Nokia color LCD with 128x128 pixel and 256 colors.

Multi NiCad Charger - This unit was constructed in the shell of a Radio
Shack battery charger. The original unit charged only one type of battery at a
time and only in pairs. This unit allows for mix and match for AAA, AA, C, and D
cells. Each battery is individually monitored and charged. An LED
for each one flashes to show the current charging condition as follows....[Luhan Monat

Multiple Switches with Single PIC Input - There are many techniques to
implement multiple switches into PIC microcontroller. This technique requires
only one ADC pin to detect voltage level when each switch for each state is pressed
and each switch is associated with a voltage. For example : If we need to connect 16
switches with 10 bit PIC. ….(electronic schematic added 11/08) |
