Wall Mounted #79 - completed
I just finished a wall mounted RBS. (click picture to view larger image) This one measures 33"w X 22"h and has a spiral/helical lift to transport the marbles from the bottom to the top. Something new is the adjustable speed of the lift. I purchased a "universal" DC power supply which has switchable voltage. You can choose from 3v - 4.5v - 6v - 7.5v - 9v and 12v giving you 6 different speed settings. (I say 4 speeds in the video because there isn't much difference between 3v and 4.5v or 6v and 7.5v) It's as easy as switching the voltage up or down to see it go slower or faster. Interestingly enough, Low (3v) has 1 marble going, (4.5v) has just about 2 marbles, (6v) sports 3 marbles rolling at the same time, and (12v) gives you 4 marbles.
One long continuous track, this sculpture is very smooth and quiet. See the video below to see it in motion. Oh, and if you are interested, this one is for sale: $1250 includes shipping in custom wooden crate within US. : )
