The Orbe Persistence Of Vision Prototype

pinshape

Human: NOTE: This is the first prototype of a Work-in-Progress gadget *** The Orbe Persistence Of Vision V1.0 is a fully 3D printed, spherical persistence of vision, two-color display. It works using mains AC power and an AC to DC PSU, which powers two main circuits: one rotation controller, controlled by an Attiny85 and a RC ESC, and a LED controller on the rotating sphere. Power is provided to the rotating part by two pairs of carbon, spring-held brushes touching copper rings. The sphere has two arms holding 15 LEDs each, with an Arduino/Genuino MKR1000 and four 74H595 shift registers controlling the LEDs at its center. A 74LS14 trigger circuit processes rotation signals from a hall-effect sensor. Printed Parts The entire structure has been 3D printed using a BQ Witbox in orange and black PLA. To build a similar prototype, you will need: 1 x base 1 x electronic support 2 x LED arms 1 x main support 1 x panel 1 x ring 2 x sensor arms 3 x sides 1 x top (two pieces of STL) 10 x M3 x 12 mm screws 7 x M3 x 6 mm screws 8 x M4 x 12 mm nutted screws 4 nylon retainers nuts 1 x brushless motor 1 x 10A RC ESC For more details, please visit The Orbe's Github page.
