Hi
Became a gr8 fan of these engineers.
They strip chips full naked and study..
Gr8.. have a look at this image.. some transistors.. inside the chip in 150000X Zoom.

And what is this ? Intel 80286 Microprocessor?

Recover AVRs which are fused wrongly

Here some tips on how to recover AVR Microcontrolers which are fused wrongly.

I will try this some time and hope will be able to recover some of my AVRs

Cornell University AVR student projects Atmega

Hi All,
Even though I keep following this page from 2000, but I always forget the url and then google it for that.
So thought let me document it some where.
http://instruct1.cit.cornell.edu/courses/ee476/FinalProjects/

I think I studied the basics of Atmega ( or any Micro controller ) from going through this page and reading the codes here.

At the end of academic year ECE476 Cornell University students produced about 40 new projects mostly based on Atmega32. As every year students have their responsibility to choose their own final project. So there you can find various interesting ideas and designs including video games, robots, MIDI synthesizers, clocks, speech recognitions and so on.
The best I liked is the prototype board for Atmega32 ( 40 Pin megas)


I have often surfed inside this pretty big knowledge base and found ideas, solutions and inspiration for my own designs.

KontrollerLab

The KontrollerLab is a tool which can be used for developing microcontroller software.

The KontrollerLab uses these tools to make developing easier:

• avr-gcc and helper programs to compile the C files, link the object files, and assemble the ASM files.
• uisp and
• avrdude to upload and download the programs
• built-in debugger for PC-only and in-circuit debugging, currently at an early stage [05/28/07]
• serial terminal embedded in the IDE to ease debugging
• kate as the editor embedded in the IDE

True Mobile Computing (you know Only Phones are not mobile)

Hi,
here is a gr8 site which works for mobile computing. they do a lot of work on car and pc and interface.

http://www.mp3car.com

And the following info is on car parking sensor. I think i found the info I was looking at..
Lets see.. how thins work out.. ;)
