When I realized some of you guys have
done RC aircraft stuff, I just had to ask
this question. (I always wanted to do
RC myself, but it never happened.)
My Part 15 station does not have a
computer. As you may know, the
DOGGRADIO computer died about
6 months ago. Now I have a tech
friend who is searching for another
junker for me, but it will either happen
or it won't. For many years, my station
didn't have any computer, and I had to
resort to all kinds of goofy but interesting
ways to automate the programming.
Tape machines on timers - relays and
resistors across the audio line to turn
one source down so an ID could come on,
that sort of thing.
I have a bunch of little MP3 players, an IPOD,
and a couple of digital voice recorders that
actually have amazing audio fidelity. I was
stunned to see that a 40 dollar Sony digital
voice recorder could sample at 192 kB/sec.
If you feed it with an EQ and a compressor/
limiter, you can record music on it, and it
sounds surprisingly good. (Mono, of course,
but that's OK for an AM BCB part 15 set-up. )
So you can probably see where I'm going with
this. For instance, If I used the right kind of
timer and power supply, I could have a servo
press the play button on one of these devices,
and get a top of the hour ID, or local weather,
or whatever. I have already devised a system
where one programming source can start up
and another will automatically reduce it's
audio volume and fall into the background
or go completely silent. (I think I said that
already.)
I know the servo would have to be rigged with
a 555 timer, or something similar, so it
only presses the button for a brief moment.
The servo I saw on the Radio Shack website
runs on a low DC voltage, and has a rotating
shaft, with some prongs on it. I'm sure you
guys can picture this - especially you RC guys.
I also have a really lame radio controlled car
that I can tear apart for a servo.
Could it be used to press a "play" button?
The MP3 player I have in mind has a fairly large strong
button. I think it's possible.
What do you think?
(And now, back to the Carrier Current experiments.)

I'm the cleaning lady in your office.
You were still logged on.
Why don't you just try it.

OK.
You missed a spot on the rug
over by the door.

Could there be a serious industrial accident in which you decide to manually push a button but your RC servo jabber decides to spear your finger and you become surgically part of the whole thing?
Could it snag your pet?
Zelda sounds like a helpful co-worker.

Set your RC jabber finger to randomly flip channels on the TV remote.
