I made a new thing...

Correct
That was where the idea came from.
Mine had an upright backboard with various instruments fitted and clamps on the bench to hold the various alternators, motors or whatever. Loads of sets of connectors.
The backboard was two 8x4 sheets of bakelite therefore 16 foot wide and the top was 4 foot up from the bench. To reach the "BIG RED SWITCH" you had to climb on the bench but nothing happened until you had climbed down.

I did build a four foot cube box once with a movement sensor underneath. It was labelled "Do Not Touch". Used to leave it lying around in Police Headquarter Control Rooms. Touching did nothing but move it it started squawking like mad. Raised a few laughs, but in those days I was able to keep a straight face.
