After my recent Davros / 6th Doctor encounter - I had a look through Revelation of the Daleks. Found this really cool gizmo.

That certainly is a cool-looking gizmo! Thanks for taking the time to grab these screencaps for us, warmcanofcoke, it's really appreciated.

The row of switches across the top of the device are square-shaped LED push buttons, similar to these:


And I could be wrong, but above those switches there appears to be a 3-position rocker switch, similar to this one but without any graphics.

(As I said, I could be wrong on this one, it may just be a random detailing, but the shape and the lip around the edge seem to suggest it is a rocker switch.)


There is also what looks like an LCD screen on the bottom of the gizmo - as for that middle part, anyone's guess is as good as mine!

Kind regards, The14thDr

Under those switches, it looks to be a scientific calculator with a piece of plastic over the top

Looking back over those images, I think you're right there. Now you mention it, that definitely does look like a scientific calculator of sorts (now comes the hunt for identifying which brand calculator was used )

the box it self, looks like one of those large "Jiffy" boxes. The screws in the corners give that away. Here's a grab of just the box.

It's definitely a rocker switch, 14th. It could be 2- or 3-position as they come in both kinds. (On the prop it could have just been a simple ON/OFF rocker that turned on the battery power to the prop's other lights and buttons.) I've seen these in Radio Shack-type stores, and they do come with no graphics on them - plain black.

(Radio Shack - soon to be a thing of the past the way things are going for it, at least in my area.)

Back in the 80s There were probably 3 sizes of display and the companies were forced to size their product accordingly. So any calculator about that width would probably work.

Somehow I remember posting this, but I can't remember. Got a pic of the actuate prop.

So the actors were holding the prop upside-down? I love Doctor Who!

A project box, a rocker switch, some light-up push-buttons and a part-disguised digital calculator... Ahhhhh, BBC prop-making at it's best.

Well, it's supposed to be an alien device.  And the prop builders at the time had time and budget limitations.  And never thought people would be poring over hi-res images decades later, so what look to be inverted human numbers are almost certainly alien characters.  

That still doesn't explain Tom Baker regularly pointing the "bullet" end of the sonic screwdriver at things, but that's another story.

The only thing I would say, is that I don't think the buttons on the prop are momentary because the lights stay on. But the look is spot on!

Actually they are latch buttons, because when he started activating the bomb, he tun out the button lights one by one till the final button & BOOM.
