Vibration Monitor (Hyde, Wanttaja?)

Yeah. I wonder whether head movement would produce enough power... like
the 'self-winding' watches of the 1970s.

Probably not, but you don't need a lot. I guess it depends on how long you
need it to operate. Using modern digital amp chips (which are amazingly
efficient), you can keep consumption down. A couple of gumstick batteries
might be alright.

Not necessarily... I guess you're talking about a metal firewall
shielding the signals, right? But, assuming a fibreglass cowl, mount a
self-powered repeater someplace where the engine instruments can see it,

That kinda goes against my "as few possible components between the source
and the destination" philosophy. I think you'd have to just locate the
receiver on the firewall and put an antenna through.

Yeah, I know that none of these things is quite right, right now.

If you don't keep working through the possibilities, you might miss an
opportunity to invent that new gadget that everybody just has to have.
Personally, I'm not hopeful that there's a big opportunity for blue tooth on
home-built airplanes, but there might be a couple of really good
applications.

First thing would be Bluetooth headsets... no more cords tangling round
the cockpit.



Not to change the subject but where did they come up with
'Bluetooth anyway?... (just lucky maybe?)

I'm typing out loud here...

When I suggested bluetooth the other day, what I had in mind was a kit
that you would temporarily hang on an airplane for specific tests, much
like we hang all the orange on Navy aircraft for flight tests. Much more
accurate pitot-static, vib sensors, postion sensors, data loggers, etc.
You could, for example, have a kit for flight testing an RV-8. Pop it
on, do the tests, and remove it. Or it could be used for "external
stores" such as a camera.

Afterward, I contemplated replacing all signal wires with wireless. So
any wire not carrying power could be replaced. This might be especially
useful for a refit, where access is far more difficult than during
initial construction.

Other harebrained ideas...two planes in semi-close formation could
network via bluetooth. Why? Could be low prob. of intercept comms on a
private channel, sharing of nav data, text messaging, ipod music files.

There's an ongoing thread on rec.aviation.soaring on bluetooth and
cellphones aboard planes.

So was the internet for a while.

I'm thinking of just wireless in general, of which bluetooth is an
implementation (with a really catchy name.)

Not at all. TCP, the original name for "TCP/IP" that we know today,
was designed to meet certain military needs but the bigger issue of how
to communicate through widely-disparate networks was _THE_ problem.
You can look up the IEEE Trans. on Communications paper by Kahn and
Cerf. 1974 as I recall.

Yea, I guess I meant the Internet as in meaning the http protocol and
WWW, which took what was a nifty way of hooking computers together and
turned it into an incredible way to hook people together. In short, the
"killer app".

Bluetooth is still waiting for the killer app. I think as ubiquitous
computing continues to grow (everything will have computers
embedded...everything) the ability to form networks on the fly will be
needed. But I digress from airplanes...
