A robotic coffee table that draws beautiful patterns in sand while you watch. Unlike others you may have seen on youtube, this table can draw at up to 2000 mm/sec. No time lapse necessary!
Former electrical engineer, currently dentist, long term member of Milwaukee Makerspace. I design and build machines like 3D printers, Van de Graaff generators, and the Arrakis sand table exhibited at the MakerFaire.
