When you try to reverse engineer some $5 toy but the ICs Datasheet is only in chinese ;-(
And Google translate for pdf sucks.

@jAsE of course.
But datasheet is always useful.
And helps me to complete the "work" a lot quicker than checking everything manually.

There is software for designing boards so DIY that shit and drink some pis- I mean beer

The macgyver meme is fitting

Pleco is a great dictionary app, you could try that instead.

Visual recognition of characters is a really hard problem. To counteract this, many systems (Google translate included) has a character drawing tool you can use to look up things instead.
