My partner and I are trying to develop a Ouija board magic trick, where someone can control the position of the Ouija board planchette. The panchette would contain hidden pieces of metal, and the board itself would have an electromagnet inside that is repositioned by two moving rails. This electromagnet would be able to stay hidden while moving the panchette "magically". This electromagnet will need to have its power controlled by a bjt circuit in order to provided the needed current. The rails would each be controlled by linear feedback control systems using IR displacement sensors. These rail control systems and the magnet BJT circuit would be controlled by a micro controller connected to a bluetooth receiver (all on PCB we design).
The receiver (we plan to purpose the HC-05 Bluetooth Module) would connect to an iPhone app that we would develop and send a PWM to the controller that would tell it to turn on the magnet and move up, down, left or right, or turn off the magnet. As of now we are imagining it to be powered from an electrical outlet as opposed to batteries for simplicity.
We would love to hear feedback on the idea, especially related to bluetooth experiences people have had. We are currently considering the HC-05 Bluetooth Module as our means of BT control and researching microcontrollers (possibly MSP430G2 MCU) to use on the final design. But we plan on using an arduino for the development phase.
