How to use External Interrupts on an ATmega168

Daniel Garcia from Protostack has made a good tutorial describing the steps to Understand How to use External Interrupts on an ATmega168. It is nice to forget about manually coding to look for changes in state of inputs and other conditions within the microcontroller. Interrupts allow us to keep on doing real work while the system keep monitoring for changes. “Microcontroller interrupts are just like that. The microcontroller is executing

1953 Radio upgraded and now plays MP3s

I had never heard of the system that this radio used to be used on. It was tied into the telephone system and received the audio programming over the phone line. Since this system has been discontinued the 1953 Radio was upgraded to play MP3s and FM Radio. The neat thing about the conversion is that it still uses all the original electronics to make the sound so it still

IR Jammer Review

John Boxall of Tronixstuff is known for his electronic kit reviews, he recently did a hands on build review of our IR Jammer Kit. You have to love his Fluke meter, if you haven’t seen one of these before you might think it’s a meter the size of a display but it’s actually a normal sized meter with a removable display. This would allow the display be placed in a

DIY Resistors Decade Box

Kiriakos Triantafyllou from Volos – Greece is a 40 years old  Industrial electrician. He shares this project on the EEVBlog Forum which shows us how he built a professional looking DIY Resistors Decade Box.  Have a look at some of the very neat wiring, I am thinking this looks better than some of the vintage electronic gear I have taken apart where everything used to be point to point wired.

MSP430 Based Meter Clock

You all know I have a thing for meter clocks. Instructables user Doug Paradis built this one around the MSP430 microcontroller platform, check out the cool variety of meters that he is using! I love the big clunky looking Simpson meter that is being used for the hours. Doug got his inspiration from the ShareBrained clock. Via: Hack a Day “It has 3 push buttons, two of which allow you

CMU Snakebots Climbs Tree

We normally see snakebots swimming in pools and they can climb inside pipes but check out how well this CMU Snakebots can Climb Trees, it is a creation from the Biorobotics Lab at Carnegie Mellon University. Via: Botjunkie “From the Biorobotics Lab at Carnegie Mellon University, a snake robot (Snakebot) demonstrates how it can climb a tree and look around. Please keep in mind that this robot climbed a specific

Recording Emotions with the Emotiv Headset

Robert Oschler sent in this interesting project which allows Recording Emotions with the Emotiv EEG Headset to sense your mood. Just like the read receipt tells you if and when your email was read this would let you know what type of emotion it conjured. “EmoRate is an application that demonstrates the power of Affective Computing, a technology that allows computers to detect and react to human emotions and will
