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
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
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
Check out this great Windows Home Server built into Fine Furniture build over at Once Around the Block. The build is broken down into build post 1, 2 and 3. The finished system looks great but I think my favorite feature is the power on light which is an edge lit piece of plastic that has been inserted into the edge of a drawer. The power on button has also
The prize this week is a loupe magnifier, this will let you get a close look at whatever you are working on. This contest will run for one week (Sept 4 – 10, 2010) . Ending time is based on central standard time. To enter, identify the item pictured above and give an example of what can be done with it. Please do not give the answer in the comments.
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.
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
