proposal
At the ARC of our school, we can only borrow basketballs or other balls from staff. As a result, we want to build a machine to dispense those balls. By scanning their IDs, students can get those balls from the machine. Also, they can return the balls to the machine by putting back the balls and scanning their IDs again.
We use a RFID as students' ID and we have two buttons which are “borrow” and “return”. In the machine, we put balls in a channel. The ball comes out at the beginning of the channel and people return balls at the end of the channel. At the bottom of channel, there are pressure sensors to measure the weight of balls. As a result, we can know whether students return the ball or not. We will use LCD to display the remaining number of balls inside the channel. We will put a motor in the machine to push the ball out of the machine. The channel has a slope at the exit to prevent the balls from leaving the channel. In addition, there will be an IR sensor at the exit. If the sensor detects the ball, the motor will stop to make sure that exactly one ball will leave the channel. If a person returns other things instead of balls, the pressure sensor will detect it and turn on the alarm.
For our project, we adjust our scalability that we build a machine that takes golf balls or baseballs. However, we can apply our machine to take basketballs in real life in the future.

Easy Cube Clock

Featured Project

Today's alarm clock market is full of inexpensive, but hard to use alarm clocks. It is our observation that there is a need for an alarm clock that is easy to set, and turn on and off with little instruction. Imagine an alarm that is set with the intuitive motion of flipping the clock over. When the alarm is on, you can see the alarm time on the top of the clock. To turn off the alarm, you simply flip it over to hide alarm display. Out of sight, out of mind. The front face of the clock will always show the current time, and will flip to the correct orientation.
