The PPOD-mini is a miniaturized version of the Programmable Part-feeding Oscillatory Device {[http://lims.mech.northwestern.edu/projects/frictioninducedforcefields/index.htm PPOD]} found in the Laboratory for Intelligent Mechanical Systems (LIMS) at Northwestern. The PPOD-mini utilizes six speakers that act like actuators. The speakers are connected to a PVC plate via flexures of tygon and iron. In its current implementation, the phase of the speakers can be controlled independently, giving the device six degrees of freedom. The movement of objects placed on the PVC plate can be controlled by changing the phases of the speakers. |

The PPOD mini measures about 12" x 12" x 8" and can be plugged into a wall outlet for power. It utilizes a switch to start the changing algorithm, a keypad for input to change the speaker phases, and an 16x2 line LCD for user interfacing and to output the speaker phases. A PIC 18f4520 provides the computing power. Each speaker is driven by an H-bridge, which is powered by a 10W power supply from Marlin Jones ([http://www.mpja.com/prodinfo.asp?number=17635+PS]). The speakers are 1W, 16 ohm speakers from Jameco. |

Introduction
The PPOD-mini is a miniaturized version of the Programmable Part-feeding Oscillatory Device {PPOD} found in the Laboratory for Intelligent Mechanical Systems (LIMS) at Northwestern. The PPOD-mini utilizes six speakers that act like actuators. The speakers are connected to a PVC plate via flexures of tygon and iron. In its current implementation, the phase of the speakers can be controlled independently, giving the device six degrees of freedom. The movement of objects placed on the PVC plate can be controlled by changing the phases of the speakers.
The PPOD mini measures about 12" x 12" x 8" and can be plugged into a wall outlet for power. It utilizes a switch to start the changing algorithm, a keypad for input to change the speaker phases, and an 16x2 line LCD for user interfacing and to output the speaker phases. A PIC 18f4520 provides the computing power. Each speaker is driven by an H-bridge, which is powered by a 10W power supply from Marlin Jones ([1]). The speakers are 1W, 16 ohm speakers from Jameco.
