Arduino Proximity Alarm
Lucas Reed @ instructables.com has build a proximity alarm using Arduino and an ultrasonic sensor from Parallax. If a nearby object is approaching then the alarm will sound and an RGB LED will light up. He writes: An ultrasonic rangefinder and Arduino microcontroller will check for...

Controlling Bus Pirate with Python
Scott Harden show us how to control the Bus Pirate with python and give us example code. After using the AVR-ISP mkII for years (actually the cheap eBay knock-offs) to program ATMEL AVR microcontrollers, today I gave the Bus Pirate a shot. Far more than just a microcontroller...

What Will Happen to Moore’s Law in 2021?
Moore’s law states that the number of transistors doubles every two years. Rachel Courtland from IEEE Spectrum explained the sharp turn of Moore's law in 2021. Chip manufactures will switch to another way of boosting the density in the chip by having multilayer chips using vertical...
