VGA Test Box is VGA tester project created by Chris. The goal of this project is to create a device that is capable of outputting VGA signals to a CRT monitor in order to display figures, text and characters. Timing is a core essential in this project. The project use Microchip PIC microcontroller at [...]

We know that most flashlights require three cells because they are regulating output current with only series resister. The odd number of cells except one is not good, and a margin between VLED and VBAT is too small, intensity of light is affected by variation of input voltage within the battery life.

Atmel launched its new AT90M family of secure microcontrollers designed for Machine-to-Machine modules. By using GSM or UMTS networks, these modules provide wireless connectivity to a range of equipments that communicate without human intervention.

Based on the 8-/16-bit RISC core allowing single cycle instruction execution, the first device AT90M25672RU embeds 72 Kbytes of EEPROM data memory, [...]
