"Marble Machine" by Wintergatan Videos for Engineers
Maybe you are one of the more than 11 million people who have
already viewed this incredible "Marble Machine" video, by Swedish musician Martin Molin. Molin designed
and built his wooden music machine using aircraft plywood, ball bearings, Lego blocks, pressure transducers,
plastic tubing, lengths of wire, springs, and a host of other off-the-shelf components, none of which
appear to have required custom metal machining. The huge wooden gears were designed on his computer,
ut out on a band saw, and assembled with glue and screws. 2,000 metal marbles are the lifeblood of the
instrument which, by function, must be classified as percussion. Even the integrated base guitar is
'played' via striking by marbles a la hammers hitting piano strings (which is
a percussion instrument). In fact, the way each event is triggered is exactly the way a wind-up
music box mechanism works with little protruding nibs controlling timing and initiating tones. Mr. Molin's
innate sense of 'how-to' is
demonstrated in devising
a method for creating a snare drum effect with grains of rice and achieving vibrato on the xylophone
with variable-geometry resonance slot. Most, I will guess, have only watched the final production -
which had me nearly mesmerized and awestruck by the juxtapositioning of mechanical design genius, a
keen musical sense, the ability to create and implement hardware, and even having a handle on integration
of electronic sensors. This is the penultimate realization of a
Rube Goldberg
contraption and a Dr. Seuss
creation a la those played by "the Whos down in Whoville."
As an RF Cafe visitor, I assume you are interested in the details of the Marble Machine's evolution
and operation. Therefore, below the main video are posted some of the accompanying videos showing how
the whole thing came together.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed
formulas and reference material while performing my work as an RF system and circuit
design engineer. The World Wide Web (Internet) was largely an unknown entity at
the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps
while tying up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...
