65 Bike Safety Sensor

One common problem when biking on campus is that you can't always see what is going on behind you. Sometimes it can be dangerous to turn your head around and take your focus off of what is in front of you. We plan on creating a device that can alert you when other bikes or cars are coming up from behind you, and want to pass. There is a product online that can do this with radar, but it is very expensive at around 300 dollars. It could be made cheaper using another type of sensor.

The object will be a belt with either ultrasonic or LiDAR sensors attached to it. The sensors will be used to measure distance and alert the wearer when an object exists in a blind spot or approaches too quickly. The belt will vibrate on the side that the object is so the person is alerted. This device will probably need to be battery powered, and have a long life.

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.
