This is a very nice project made by the famous geek blogger Mark, from geektechnique.org, he made a manual charger for iPod (can be used to charge mobiles too) using your bike. This is worth looking at!!!
This is another thing that I have done a long time ago, but now I’ve decided to release it as a HowTo. I had an old keyboard lying around and I was thinking how it would be to have one black keyboard (even though it’s quite easy to just go and buy one.) I didn’t take pictures of all of the segments, but I’ll try to explain them:
Nowadays, Winamp has full support to keyboard shortcuts. But some time ago, when Winamp didn’t have this feature, I was thinking of a way I could change the music just by pressing one button, it would make it faster and easier to change songs, especially during games. So I decided to make an external control to it. I found one Winamp plugin that shows how to configure an external control using the Serial Port, being able to make 4 or 15 buttons control. I decided to make this, step-by-step, how to do it, hope you enjoy.
