James O'Neill explores a Transcend SD that he believes it's the smaller Linux server. It's actually a 16GB memory card, an ARM processor and a WIFI chip all in an SD card package. The way these cards works is different from the better known Eye-FI card. They are SERVERS : they...

Rahul Sreedharan introduces us to TI's MSP430 microcontroller using LaunchPad board. In this tutorial we will be exploring the workings of a MSP430 based microcontroller from Texas Instruments. MSP430 is developed by Texas Instruments as an extremely low power 16 bit architecture for...

Rahul @ Xanthium has posted a tutorial on interfacing ATtiny with L293D: In this tutorial we will learn to interface L293D with ATMEL ATtiny microcontroller and control them bidirectionally.The microcontroller used here is ATtiny2313A which is interfaced to two L293D motor control...

Raj @ embedded-lab.com published a revised version of an old project, a programmable Relay Switch based on PIC16F1847 (or PIC16F628A) that can be used is various automation applications and you can independently set ON and OFF timer with maximum time interval 99 hours and 59...

by Susan Nordyk @ edn.com: Bosch Sensortec’s BMX160 is a 9-axis motion sensor touted as the smallest in the industry for wearable and augmented/virtual-reality devices. The miniature device is housed in a 2.5×3.0×0.95-mm, 14-pin LGA package, small enough for smartphones, smart...
