OT: aide memoire/ interlock?

[N_Cook]

I run a series of public talks where the speaker uses their laptop
coupled via external monitor to my video projector. Because of changing
operational reasons it will be better if the speaker was positioned
away from where his laptop is. To that end I will be getting a
radio-linked laptop r/c for stepping through a powerpoint and combined
laser pointer.
The little USB receiver unit I can tie to the SVGA lead to the
projector, so the speaker cannot walk off with the dongle. But how to
avoid him putting the transmitter in his pocket and walking off with it?
All I can think of so far is attach it to a cord lanyard , so he has to
place it around his neck, makes it less likely to walk off with it
unnoticed, but not infalible as he can still put it in a pocket.

I've thought of one possibility. A padlock , small but large enough to
be an encumberance. The small key threaded permanently through the
lanyard. Then make a cable to the video projector locked into place
with the padlock, using a pair of cable ties or something. In use the
padlock locking the IEC lead to the projector. On packing up, the key
to unlock the padlock is required before stowing the projector, then
only have to remember to transfer the padlock hasp to close around the
lanyard instead, until the next outing.

The Lady from Philadelphia suggests...

As you are running the talks, can you not keep an eye on the speaker, and make
sure he doesn't carry it off? This should be easily accomplished, as you will
have to retrieve this... dongle... as each speaker completes his talk.

I have seen wireless alarms that are made for pets or children that
make noise when far enough away from the transmitter. Maybe one of
these could be fastened to the device in question. If it gets too far
away it will remind the person to pull it out of the pocket and return
it.

I just got it today , the size of a small pen, so one of those
out-of-proximity gizmos is a bit large and wrong sort of dimensions to
fit to it.

It all gets too hectic all at the same time , and I'm male so no
multi-tasking ability. The receiver is a little bigger than a standard
USB plug, a tiny protrusion beyond it. There must be alot of those left
in laptops after such talks , much smaller than a thumbstick, which also
get left in place very often

 

Let me get this straight.

You go set up a public venue for someone to speak in public.

This is an ongoing thing.

You think they will steal your equipment.

You have no recourse against this person or people.

Is that correct ?

Exchange the transmitter with the speakers cellphone.

Claim it can disturb the transmitter. When the speaker returns the
transmitter, (s)he gets the phone back.

too underhand. A slight variation to my lock and key. The tiny receiver
slots into the pointer pen , with a magnet to hold in place. A piece of
cord to the key , slid into the pen. The receiver USB plug tied to the
SVGA cable with enough lacing cord to reach the other side of a large
laptop if required.
As the speakers always use a ps with their laptop, then the little
padlock , painted with flourescent paint and a length of hi-vis hologram
tape, also tied to the VGA cable and hasp looped around their ps lead.
I have been left with speaker's ps before, so should avoid that
situation as well. Explaining upfront for the padlocking business

Attach it with a cable to a lockable dog "electric fence" collar. If he leaves
the room with it - Zaaaaap!

Or, attach it to something too big to walk away with.

Like a restroom key at a gas station, where it is chained to a rusty,
used brake drum?
