I borrowed my friend's soldering gun to fix my fibre optic lamp. It had been dead for almost 2 years. Plus it's rather frustrating to look at it standing alone by the wall divider everyday. Being an electrical and electronic engineer who never fix this 'smple toy' can be extremely intimidating.
So, basically I just cleaned it and replace a wire in it.
Just as expected, voila! It's fixed!
Dang... I should have fixed it years ago...
