Most useless Lego machine

Fun & Games Home

Inspired by the most useless machine, Karel decided to make a clone using Lego and some switches.

Also, this hadn’t occurred to me until now, but this kind of machine could actually be used as a time delay, in the same manner as a monostable multivibrator. Maybe it could be used to debounce a giant switch?

    I made a revised version with a reversed action, just like the electronic ones. I replaced the main on-off switch by a toggle switch.

    Here it is:
