Hi guys.. Sorry for the lack of updates.. I've been a lil bit tied up with lots of things.. Mostly due to my Final Year Project. So here it is, Digital Electronic Padlock. This invention has been accepted for conference by the IEEE. I spent the last 1 year or so to design and implement this project. Every phase of this project has been challenging and entertaining. I had to teach myself a small portion of mechanical engineering-related-subjects to achieve completion. And I'm proud it has been completed now.

It is basically a padlock that does not require an analogue key. In return, you'd need a correct password to make the padlock unlock itself. When you enter a correct password, the padlock would unlock itself. Watch the video for a brief demonstration. Oh, did I mention that the padlock is water resistant?
