The super macro guessing game (5)

Is this a bit of wirelass computer technology, like a mouse?

Chris already said no to it moving a cursor on the monitor around, so unless it's a broken mouse, it can't be that.

Sorry ... missed that

Yes

A wireless drive?

No

The answer to TV was a little ambiguous. Is this related to video?

I was thinking a keyboard but can't think of a sensor in one.

No
only very indirectly

A sensor is something which tells electrical stuff about what's around it.
A switch is a position sensor
A keyboard has an array of sensors
You got the main thing, it's a wireless keyboard

Close enough for it to be yours, but what's the thing in the photo? If you go back to the original post.....
and your first response to it.......

Well technically a switch senses something but it's not what I would normaly consider a sensor.

But it's like they say: Technically correct is the best type of correct

Is the thing you're showing the electrical contacts for the switch?

Soz, I teach electronics. I'll have you know a "pot", like an old fashioned volume knob, is a "rotary position sensor".

No, the thing you're looking at is entirely plastic.

Yeah, I already agreed that technically you're correct. And I do know what a potentiometer is and that it is used with a voltage and then the "POTential difference" is measured or used to drive other components.


I mean technically speaking a loudspeaker driver is a sensor but I wouldn't call it one. I have used them in the past for an emergency microphone though

FYI I have a PhD in physics/Instrumentatio​n.

Is keyboard correct or are yOu after the more specific part? Ie. SHould I take a macro shot?

Off topic, but what is wrong with frogs?

To tell you the truth I don't really remember, it had something to do with a silly conversation in the title fairy thread a couple of years ago. I should really change that and the spatula bit.....

OOh no, a loudspeaker driver isn't a sensor, it'a just a Driver, a Process component
"Pot" is short for potentiometer. Even when it's used as a single resistor.
A loudpeaker would be classed an output transducer, unless you turned it round, then it's a sensor.

My PhD is in crystal structures in semiconductor oxidation (yawn) after a metallurgy & materials degree, but I got bored with it and subsequently did another degree in electronics & systems. Then I went on to other things again. In retirement I do some part time school (15-18) teaching. Electronics, astronomy, biology...
Except for right now....

I'm not really sure what I want to be when I grow up. A photographer, maybe. But I'm not very good at it.

Anyway I was after a description of the part of the thing, which I photographed. I mean if I zoomed out, you wouldn't recognize a keyboard, You almost guessed it in your first reply... Yes there was a clue enabling you to be very specific with your answer.
