Hi,

Anyone dissected one of these? I'm curious if it is even possible
to do so (or if they are so highly integrated that doing so just
results in a pile of plastic and silicon). E.g., could you use the
guts of the radio and interface the rest to an external mic and
earphone?

Thx,
--don

It probably depends a lot on the specific model. I have done it to a
cheap Chinese one from DealExtreme:

It wasn't even difficult.

If look at the link, there are even a couple of decent quality
pictures from its internals.

You might have to be a bit more specific there Don.

BT Earpeices could be a number of things.

To some of us in UK they could be the British Telecom standard item for
call-centre and switchboard personnel where they are on the phone for long
periods of time. These are usually the Aerolite headset but there are a
number of different makes and models available.

Alternatively I suppose you could be looking at the Bluetooth devices make
it seem that people are talking to themselves when they are actually talking
on the mobile phones.

I would expect that most of the latter ones use a cheap microscopic
microphone element. If what you wish to do is connect a different microphone
then I expect that should be possible. Sounds like you need some serious
playtime.

Ah, sorry, some confusion, there. My bad. This is more
like what I was talking about:

http://www.dealextreme.com/details.dx/sku.32062

with the differences being:

- smaller size (?)
- microphone (i.e., duplex operation)
- not a "music player", etc.

I.e., the sort of thing you use with a BT enabled cell phone
for "hands free" operation.

Ah. No, BT == BlueTooth. My bad.

Yes (good description! ;-)

I've pulled apart some small voice recorder/MP3 player devices and
the microphone in those was tiny -- though I could easily hold
it in my fingers, unsolder it, etc. Most of the BT earpieces
I've seen seemed a fair bit smaller, though. I was wondering
if there was an even greater level of component intregration
that would make attempts to *modify* them essentially fruitless.

Ditto for the "earphone".

> Sounds like you need some serious playtime.

Yeah, I was hoping to avoid dismantling one until I knew if
that would be *likely* to yield promising results. :-/
I guess it's time to make a sacrifice to the electron god...
