Since small I like to unsrew things... I like to open up and see what's inside...
Especially my toys, remote control cars, robots, anything battery operated one la...
When I goto college time...i even darer... i open up my handset, to do some maintenence cleaning. I will use unwanted tooth brush to clean dirt trapped inside PCB, clean away dust on the PCBs, affter done, then assemble back.
Sometimes the vibrations or sound goes off, I do open up and do some cleaning, tighten the screw. Then, it's work well...
Sometimes I will found extra screws, or extra parts after assembly... I dunno where the heck it came from...anyway...who cares, as long as it can work...hahaha...I am m'sian engineer wat...biasa la... Then, there is a best case, my canon ixus II drop into water, i try to open up and use hair dryer to dry it, after so many layers of parts, i cannot rmb to assembly back. So, I sell it as spare parts on ebay and manage to sell it off... hahaha!
