Corkbord Voodoo magic, with vibrations

Description

Voodoo trick is a well know by magician.  This is another creation. No partner needed.  After explainning the meaning of Voodoo (where someone harms a doll or drawing of some person she hates, and the person feels the pain),  the magician makes a drawing of  himself in a blank paper. Show the drawing to a spectator, and hand her a corkboard.  The magician fix the drawing on the corkboard, with four pins.  Next, he hands everything to the spectator. The magician stays standing with open arms, eyes closed, facing to the audience. The spectator is asked to pick up any pin and choose one of the six  X on the drawing, without mentioning where.  Ex. she pins the heart, and at the same moment, the magician feels a pain in his chest. Next, she pins the left arm, and the magician feels a pain in his left arm, and so on. The show can stop at any moment: one pin only, or two pins, or any, up to six pins.
The secret: The cork board is gimmicked with an electronic circuit, with six sensors. Each sensor send a vibration count to the magician showing which place the pin was placed.  The vibration are fixed as right hand = 1 vibration, hearth = 2 vibrations, left hand = 3 vibrations, and so on, up to six vibrations. Everything uses Lipo Battery, rechargeable, and you receive all the cables for charging. The corkboard measures 12x12 inches. See demo at
