How to flash Arduino UNO bootloader
This guide is for programming the Arduino UNO bootloader through Atmel ICSP USB programmer. If you have a diffrent programmer such as STK500, that only requires a different interfacing. It is a known fact that it is a bit tricky to program the Arduino bootloader. But if you follow these instructions...

Re: Does anybody brought colourfull contract lenses?
My personal idea... never do this. This will bring you unnecessary trouble. I guess you have natural black eyes as a native Sri Lankan? Do you know that many Europeans who are having Green, Blue or Brown eyes are using blank lenses to make their eyes look black? Also you might have seen millions of ...

Re: DIY Arduino
The first thing I would like to ask you is to use an original regulator. Duplicates doesn't give you 5V accurately. The other thing I would like to suggest is to download the schematics from Arduino site. Then have a look at their techniques, regulators used on achieving this task. Arduino is a very...

Re: L298 circuit diagram for normal DC and stepper motors
Flyback diodes are pretty much about two issues - the amount of power they have to remove and how quickly they have to remove it. In general, you don't really have to worry too much about either of these issues with a small toy motor. I use simple rectifier diodes as they are cheap and everywhere. ...
