Raspberry Pi Passes EU Electromagnetic Compatibility Testing 137
A week ago, we posted news of the delay that the Raspberry Pi Foundation faced because of a requirement that their boards be tested to comply with EU regulations. Now, the word is in, and the Raspberry Pi passed those tests without needing any modifications. From their post describing the ordeal: "The Raspberry Pi had to pass radiated and conducted emissions and immunity tests in a variety of configurations (a single run can take hours), and was subjected to electrostatic discharge (ESD) testing to establish its robustness to being rubbed on a cat. It’s a long process, involving a scary padded room full of blue cones, turntables that rise and fall on demand, and a thing that looks a lot like a television aerial crossed with Cthulhu."

Am I the only one scared by these guys?????
They think they can design a PCB yet are scared of some simple measuring equipment. (I have been involved with and designed several products which had to go through CE testing and that stuff is NOT scary if you known what they are doing).
I really hope the summary is just joking about the antennna.... if not: stay away from Raspberry Pi: it is designed by clueless idiots.

From TFA:
A cute story. Radiated immunity testing involves hitting the Raspberry Pi hard with narrow-band EM radiation, while checking (amongst many other things) that the device is still able to send Ethernet frames to a hub. The first time the team did this, the light on the hub stopped blinking: no frames were making it through. They did it again: still nothing. Finally, they discovered that the hub (which, I should point out, gave every appearance of being CE marked, so it should have been able to get through these tests itself) was being knocked out every time somebody pressed the button. Jimmy used a longer cable, put the hub outside the field, and found that the Raspberry Pi got through its immunity tests with no problems at all.
Too bad their CE certified ethernet hub failed the CE testing.... remember kids, this is what you get when you buy cheap stuff from cheap manufacturing countries.... oh wait!
