The Toy


The OhMiBod, by Suki LLC, is a pearl white, hard plastic cylindrical vibrator with audio activation capabilities. The design allows for different control capabilities through usage of different caps that fit on the end of the vibrator. The product ships with two interfaces: Audio and Knob (potentiometer based).

The audio interface takes audio from a stereo wire running from the source to a jack in the Audio end-cap. It uses a RC low band pass filter running to an A/D converter on an 8-bit microprocessor. The value is used to scale a PWM signal going to a high current, high speed switching transistor. Since there is no regulation on the vibrator itself, power is controlled through the volume of the audio being fed into the vibe. Issues with clipping can occur if the source audio volume is too high, causing the PWM signal to stay at maximum.

All parts of the vibrator run off 2 AA Batteries.

The vibration motor is molded in the plastic shell of the vibe and cannot be removed, meaning that though the control mechanism for the vibrator is modular, the physical interface cannot be changed without some modification to the control mechanism mounting units.

Tools Needed

 * Small (eyeglass) Philips head screwdriver
 * Small (eyeglass) flathead screwdriver
 * Soldering Iron
 * Some type of solder removing tool (Desoldering braid or solder sucker)

Instructions
Following instructions are for disassembly and circuit board removal of the Audio end-cap
 * Unscrew the two Philips head screws on either side of the battery spring
 * Pull cap apart, making sure not to use too much force as wires are soldered to the inside of the upper cap, which will keep the cap connected.
 * Using the flathead screwdriver, remove the glue from the top of the circuit board slots on the lower cap. Once this is done, gently pull the circuit board out of the slot.
 * There are 3 solder points on the upper cap that need to be unsoldered
 * Power/Motor - Connected to side of Upper Cap - M  on the board mask
 * Motor - - Connected to side of Upper Cap - M- on the board mask
 * Ground - Connected to bolt holding battery spring on Upper Cap - Pow- on board mask
 * This will free the board from the end cap completely

Schematics and Information
The board mask says "ZY-106C v1.2" on top and bottom.


 * CPU: Holtek HT46R47. (Note: This part is known to be a close clone of the PIC series microcontrollers made by Microchip Technologies, and is programmed similarly)
 * Transistor: Sanyo D1803 NPN Transistor
