Robotic hand.

Not sure why many of my friends now are crazy to build their first robot hand. Where they got an idea to build that? All I know they even don't have any knowledge to build it.

Then I asked them about it and guess what.... I am so surprised with the answer. They just refer for the ebook that they have bought on internet. Damn, how I can forget that. Internet is the best place for us to get what we want including HDMI cables. So if you think you want to build your own robot hand, look for it on the net.
