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.

Smart Frisbee

Smart Frisbee

Featured Project

The idea of this project would be to improve upon the 395 project ‘Smart Frisbee’ done by a group that included James Younce. The improvements would be to create a wristband with low power / short range RF capabilities that would be able to transmit a user ID to the frisbee, allowing the frisbee to know what player is holding it. Furthermore, the PCB from the 395 course would be used as a point of reference, but significantly redesigned in order to introduce the transceiver, a high accuracy GPS module, and any other parts that could be modified to decrease power consumption. The frisbee’s current sensors are a GPS module, and an MPU 6050, which houses an accelerometer and gyroscope.

The software of the system on the frisbee would be redesigned and optimized to record various statistics as well as improve gameplay tracking features for teams and individual players. These statistics could be player specific events such as the number of throws, number of catches, longest throw, fastest throw, most goals, etc.

The new hardware would improve the frisbee’s ability to properly moderate gameplay and improve “housekeeping”, such as ensuring that an interception by the other team in the end zone would not be counted as a score. Further improvements would be seen on the software side, as the frisbee in it’s current iteration will score as long as the frisbee was thrown over the endzone, and the only way to eliminate false goals is to press a button within a 10 second window after the goal.
