So what is this?

[ARW]

I know that it is a 30mm by 4mm glass capusle with some electronics inside it.

But other than that I have no idea.

[Nightjar]

It looks like a pet microchip to me.

Maybe it's um, "fitted", anally.

Looks like a coiled aerial and some components. RFID device? Could do without the curly grey pube though. ;-)

Looks like the chip from inside a car key albeit 2 times too big. How about an anti theft device for contractors plant?

Certinly looks like it

It's an RFID transponder. Coil is energised by a near-field device, transponder sends it's ID to the energiser. Usually contained inside something like this :

As others have said, looks like a low frequency transponder. TI do a

31x4 mm one:

Did Toby get the rest of the apprentice?

It reminds me of an old style reed relay. Although I can't say why the coil is actually inside the glass envelope.

[Graham.]

That was my first thought, and a similar reason for discounting it.

An interesting data sheet - thanks for the link. I see that although made of glass for biocompatibility, it will withstand 300g! It is also hermetically sealed. I wondered how it could be sealed (as it appears to be made completely of glass) without heat damaging the electronics inside. Answered at

where it says the glass has a high iron content and can be sealed with a Nd:YAG laser. Obviously the iron content isn't high enough to interfere with the signal.

Is there a magnet-onna-spring inside that coil?

A North Korean version of one of those pills you swallow to take images as it passes through?

[Simon Mason]

That is a MW AM antenna on a ferrite rod. Probably off an old pocket transistor radio.

[Andy Burns]

Might be if it was ferrite rather than glass, and the wires were wound round the outside rather than on the inside!

[Simon Mason]

The ferrite rod is underneath the coiled wire.

[Weatherlawyer]

To connect to the other two flux capacitors, you mean?
