DIY Digital Wristwatch

Introduction The main incentive behind this project was to see how much I could cram, in terms of both hardware and software, into a wristwatch-like device that is no larger than the display itself. An OLED display was chosen for being only 1.5mm thick and not requiring a backlight (each pixel produces its own light), but mostly because they look cool. The watch was originally going to have a 0.96″ display, ...

USB Media Volume Control

My most rewarding projects are the ones which i actually use. I like my audio gear so, this was the perfect companion project! On my desk i have a headphone amplifier for my AKG K702's headphones, below it i have my self built Onixia integrated amplifier for my bookshelf speakers. I have been thinking about making a global volume control for both devices for quite some time... here is the results of my effo ...

Warrior Modules contains complete electronics for joystick

Need to connect simple devices to a computer, like relays, switches, or a small display, but the computer has no parallel port or that port is in use by some other device? Using USB used to mean that you had to develop specific code for a USB-enabled microcontroller, developing a unique driver with lots of documentation and using expensive development systems.  Using USB to serial adapters is not a good opt ...

Accelerometer Interfacing with AVR

The article covers how to interface an accelerometer with the atmega32/atmega16. Before proceeding, the user must know the basics of ADC (Analogy to digital converter) of the AVR.An accelerometer is an electromechanical device that will measure acceleration forces. These forces may be static, like the constant force of gravity pulling at your feet, or they could be dynamic – caused by moving or vibrating th ...

High-voltage seven segment LED display driver with SPI interface

Seven segment LED displays are known to be resource and power hungry. But because they are visually so charming and readable from a far viewing distance and at a much wider viewing angle as compared to any other electronic displays, they are still hugely popular. The required number of I/O pins to drive the LED segments can be reduced significantly by using an additional dedicated hardware. For example, the ...
