Our goal is to design a bicycle device that could detect the physical condition and will sent alert if the physical condition fell below a threshold.

Generate electricity from mechanical source of bicycle to power the detector
Heart rate sensor (and a bio-related sweat sensor) will be inside the bike handle
The pressure sensor will be built in the saddle and both pedals
The accelerometer will be used for collision detection

Function: All sensors are connected to the power system (from mechanical energy) by wires, but they also have a secondary battery. The sensor in bike handle can check the heart rate and (salt %) to determine if the biker is in a safe physical condition. When the sensor notices it after analyzing the data, it can alert the biker to stop or to take a rest. The volume of the alert will be gentle and increase gradually.
If all pressure sensors detect pretty small value, the system will consider that the person is thrown off the bike unless he or she hits the button on the bike. We also implement a delayed emergency response system that gives enough time for user to cancel it. This feature is set to off at the beginning, the biker can choose whether to open it. For example, they can only use this feature when they are going to cycle in the some unsafe places or somewhere with few people. The collision detector will analyze the change of acceleration.

Drum Tutor Lite

Featured Project

Team: Yuanheng Yan, Zhen Qin, Xun Yu

Vision: Rhythm games such as guitar hero are much easier than playing the actual drums. We want to make a drum tutor that makes playing drums as easy as guitar hero. The player is not required to read a sheet music.

Description: We will build a drum add-on that will tutor people how to play the drums. We will make a panel for visual queue of the drum and beats in a form similar to guitar hero game. The panel can be a N*10 (N varying with the drum kit) led bar array. Each horizontal bar will be a beat and each horizontal line above the bottom line will represent the upcoming beats.

There will be sensors on each drum that will fire when the drum heads is hit. The drums will be affixed with ring of light that provides the timing and accuracy of the player according to the sensors.

Of course with a flip of a switch, the drum could be a simple light up drum: when the player hits the drum, that particular drum will light up giving cool effects.

The system will be on a microprocessor. Or for more versatile uses, it could be connected to the computer. And a app will be written for the tutor.
