    The Standard of Engineering Graduates

    Do you worry about who's designing your cars,aircraft, buildings, bridges, oil refineries, ...? (I don't worry about most of the electronic technology, because I just wish most of it didn't work! Like mobile phones, game boys, i-anythings,..) Just recently I've come across two posts (not here...

    Induction cooker pans?

    What sort of pan can be used with an induction hob? I ask here because this seems electrical rather than electronic, though I think people here will know about it.

    Faulty power connectors

    I'm not sure what I'm asking here! I'm just astonished and wonder if anyone has similar experience or thoughts about it. Out of a set of 15 power leads I have just tested, I found 4 faulty with a low resistance between the pins. They are about 3 years old, but show no signs of physical damage...
