Our friend David Marks has the knack for constructing interesting items, mostly useful. His recent credits include a fabulous doll's house for his grandchildren. He also has some long-term projects on the go such as building a wooden organ driven by MIDI technology - he is skilled at both woodwork and electronics.
However, it was with some amazement that I recently discovered his latest device - a version of the Most Useless Machine. You Tube has several videos showing versions of Useless Machines in operation.
Unique or not, David's version is really great fun. You just can't stop trying it. Last night when there was a gathering at David's house it got a lot of use. Hope you enjoy the video.
By the way, the ghostly red light was added at my suggestion.
