$400 USB stick probes magnetic fields

Remember Steorn, the Irish company that pitched a perpetual motion machine a couple of years ago? They're back with the USB Hall Probe, a $400 wand that detects fluctuations in the woo.
At Wired, Charlie Sorrel takes it down.

$400?!? Are they insane?!?
High end: A sensor probe like Vernier's Hall effect sensor: $66, plus $40 for the connection to your computer if you don't already have it (connection works with dozens of other probes). Comes with all the software you could need.
Medium end: any voltage sensor that attaches to your computer (like Vernier's, $40), plus a $20 gaussmeter.
Low end: Practically anything at all that attaches to the USB of your computer (e.g. Arduino Mini USB Adapter, $19) plus a $20 gaussmeter chip. Requires some very, very basic programming.
This is just dumb dumb.

On the plus side, doesn't violate the laws of physics. On the minus side, overpriced...

But is it danceable?

It may be worth the sticker price for collectors of concentrated failure.

Well, this is great! If this ionization rate is constant for all ectoplasmic entities, we could really bust some heads! In a spiritual sense, of course.

Well, they have to use most of the money to pay the settlement from the lawsuit (Physics v Steorn).
