To mark the occasion of 31,000 Kontraptionist Lab followers, I bring to you the guts of the lottery machine clock! Yes, that’s right, instead of random numbers, it tells the time.
In spite of all the speculation at the opening reception, there are no magnets, no microchips, no weights, velcro, or magic of any kind here, just good old fashioned slight of hand.
Four stepper motors drive four large Multi-Ply gears housing the display balls, and no fewer than four high power blowers supply enough air to make all of the balls dance around. A fifth blower is all it takes to launch all four of the appropriate balls in to their final display positions.
On display now at Callicoon Fine arts in the lower east side

Watch out for the brilliant bit where it rubs off the old time.
