Description: We will build a magic wand that has tri-axis gyroscopes and accelerometers inside to detect the movement of the wand. If the detected hand gestures fit with one of the spells, it will emit an ultrasound and the player hits by this will have his game blood level decreased (it works like in Harry Potter!). We also need a microcontroller that connect all of the wands to the game center which keep tracks of score and decode the spellâ??s gesture (received wirelessly). Another main component in the project is an general receiver that can be connected to tablets for UI display to enable score tracking. Also, player has the freedom to input additional spells besides those already hard coded to the game, so having a LCD display will be helpful for this interaction.
Since the gameâ??s components are easy to carry and our gesture detection are not limited the range of camera, it will be a fairly easy to carry game. There is no game like this in the market besides laser tag.

The goal of this project is to design a low cost BMS (Battery Management System) system that is flexible and modular. The BMS must ensure safe operation of lithium ion batteries by protecting the batteries from: Over temperature, overcharge, overdischarge, and overcurrent all at the cell level. Additionally, the should provide cell balancing to maintain overall pack capacity. Last a BMS should be track SOC(state of charge) and SOH (state of health) of the overall pack.

To meet these goals, we plan to integrate a MCU into each module that will handle measurements and report to the module below it. This allows for reconfiguration of battery’s, module replacements. Currently major companies that offer stackable BMSs don’t offer single cell modularity, require software adjustments and require sense wires to be ran back to the centralized IC. Our proposed solution will be able to remain in the same price range as other centralized solutions by utilizing mass produced general purpose microcontrollers and opto-isolators. This project carries a mix of hardware and software challenges. The software side will consist of communication protocol design, interrupt/sleep cycles, and power management. Hardware will consist of communication level shifting, MCU selection, battery voltage and current monitoring circuits, DC/DC converter all with low power draws and cost.
