Beta Bugs

Most of my gadgets are tested aggressively, till i seriously stress my faculties. I work alone and i do get some online feedback.

Some gadgets were made to demonstrate some electronic concepts, never intended for any serious application.

It is more for the pleasure of working with JavaScript and CSS, Some were dynamic tutor pages i had made earlier. Converted to iGoogle Gadgets.

There may be known and unknown bugs in my code. Let me know if you find one.
