A couple of weeks ago, I bought an FM radio from the 99 cent store
(Made in China).
I then decided to take it apart, to see what neat stuff was inside.
The first thing I noticed was a chip (microcontroller?) that had
scratches on top. After a closer look, it looked like someone took a
Dremel-like tool to sand off the chip markings.
Sounds like a good idea, to make reverse engineering tougher, but is
this standard procedure?
Only by people that don't understand that it's a waste of time, as any reverse-engineer worth their
salt will be able to figure out what the chip is in typically a few minutes.
I knew a couple of guys who refused to put the pin numbers of simple commodity ICs like op-amps and
comparators on their schematics. It used to drive me nuts. Their 'excuse' was that it made it harder to
copy. Unbelievable stupidity.
