I've now investigated the projection facilities at the hall.  The
connection to the projector is a type I have never seen before and for
which I have no adaptors or leads.  It is on a box screwed to the wall
at one side of the hall and nowhere near the position I want to place
the demonstration apparatus and camera.

For the demonstaration I'll use my own projector and the PowerBook - and
forget about a camera for showing the detail.  With luck there won''t be
a large audience and they will all be able to sit close enough to see.

Thanks to everyone who tried to help.

Can you take a photo of this connector and compare it with what you find 
on the web?

Does the hall provide a technical specification that would show the type 
of connector and signals required?

I shan't be in the hall now until the actual presentation next week, so
it would serve no practical purpose.

None that I know of, it's just a village hall.

At a guess I would say HDMI, remote possibility that it's displayport, see

Spotlight should find it for you. It'll be under display settings, I think.

Keynote should do it, I would have thought.

You can also use the Preview app, admittedly for pretty basic presentations.

It doesn't appear to have Preview. (OS 10.6.8)

Snow Leopard certainly came with Preview.

You can also use Quicktime Player:
File: New Movie Recording
will show you the picture from the internal camera.
Set it to record and then type Command - F for full screen.
(You will also get a recording, so make sure you have some disk space for
that.)

I'm pleased to say the talk went well, picture at:
<https://chippenhamradio.club>

I realised that I needed light on the demonstration equipment, so I
brought along a stage lighting bar which you can just see at the top of
the picture (right of centre).  By directing the light only where it was
needed and using a small screen for the presentation, I got sufficient
contrast and brightness on the screen.

We arranged the chairs in two concentric horseshoes but several more
people turned up unexpectedly at the last minute, so we had to put in a
third row.  I'm not sure if they were able to see all the detail but
nobody complained.


Many Thanks to everyone on this group who tried to help with the camera
problem - I don't think it could have worked without a lot more
equipment and wiring.

Well, that was a surprise... I've always thought you were in Australia! And no

Sorry - that probably came across as quite random! Not a ham radio user,
but I used to spend hours scrolling through SW bands listening to weird
stuff. Great fun!

Nowadays I often use WebSDR for sw listening. 

<http://websdr.org>

The Twente site gives reasonable coverage of the sw spectrum.

Muat admit, I've been looking at SW receivers lately... I used to have a Sony
ICF-SW55. That was an amazing piece of kit & I do miss it. Bought it in the
early 90s & used it when i was in Moscow for a few years. There was very
little else in terms of english language audio/visual entertainment back then,
apart from CNN. I'd cruise the airwaves and keep a little notebook of
where/when different countries broadcast their english language programs.

You could always get a SDR box to plug into your Mac. I bought one of these
but
of course you need a decent antenna system, so the wedsdr solution may be
better.
