Computer battery broken? No problem! Just weld on a 12V boat battery. 70 pounds is a bit much for a "portable computer," but it's better than no computer at all!
"The cable shorted out so we cut them shorter to get rid of the short (yo dawg, we herd u liek shorts) and soldered them in place where they belong. Another short, this time nearer to the computer end of the cord, so we put Q-tips and tape to hold it in a place where it charges happily."
And they all charged happily ever after!
From the Submitter: I made this contraption to keep my laptop from overheating. It cooled from 69ºC to 39ºC within ten minutes. And yes, those are 2.1 kV transformers. And yes, that's a roll of duct tape.
Let me label that for you:
1: Laptop that he just can't let go of. 2: Books that he tried to read and failed. The Silmarillion (left) and Ulysses (right). 2 - again? come on dude, you only had to count to 5: Anyway, mentioned above. 3. CPU fan stolen from parent's desktop. 4: The crowning achievement of the piece, almighty duct tape.
