hey all, I'm trying to create a miniature version (less balls) of this just because it looks cool: [BMW Museum - Kinetic Sculpture] It looks like they attach string to a ball and then this gets moved up or down on the y axis. Together they create a 3d object. I thought about stepper …

Hi, first sorry for my english but it isn't my mother language. Me too am working on the same project, iv'e found on ebay a cheap stepper motor with an uln2003 drive board, two stepper and two driver board cost around 6 euro, and it can easily move a little ball or something similar, if you wont mor…

Hi, I add news on the project, done! I've made it with an array of 16 motors, 4X4, that is the least that a mega can drive with this tipe of motors, with other type I can drive 35 motors with only one mega board, but those cost 10 times more the first one, so I wait to see if someone is interested a…

@Radicator :Please provide me way of making it.I am working on it.

what kind of motor and driver were talking about ? And if you want to hook up like 50 motors do sync arduino boards ? or do you use kind of addressable solution ?

Mega can do 48 Servos I think other motors will need at least 2 pins for up & down, so now you're looking at syncing multiple cards. Google Search the world's information, including webpages, images, videos and more. Google has many special features to help you find exactly what you're…

thx for your reply Cross...question What do you mean with "Automate that even, use 3 16:1 muxes (ex. DG406) to read limit switches for calibration. 3 inputs, 4 channel selects," i was thinking of using an ultrasone for calibrating strings ( pull up weight.....when weight distance is shorter than 1…

So a setup like this (can't really show the 3D-ness of it, but I think it gets the idea across). Try a couple of servo, see what's needed to lift 500g (~1 pound). [Servo-spool-ball.jpg] You might be surprised and find a Standard Servo is all you need, and the biggest part of the problem is secur…

thx Cross...going to do some tests
