Automatic Bicycle

The Mechatronics class at South Dakota School of Mines & Technology has students form groups for a maze solving robot and free projects. My group decided to make an automatically shifting bicycle for our free project. We set up the bicycle to monitor the current speed and change the current gear in order to get the maximum workout. Finding the speed The bicycle tracked speeds at two locations on the bike.

Electric Cane

One of the labs for my Microprocessor Based System Design class involved making an electric cane for the blind. The cane worked by first taking measurements from an HC-SR04 sonar sensor. The range of the nearest object could be found by measuring the time from an initial pulse to a returning pulse. Feedback was then sent to the user depending on the distance of the object. The device had two methods for creating feedback: a small vibrating motor and a small speaker.

Heater Controller

A simple bang-bang controller on a PIC32 microcontroller. One of the labs for my Microprocessor Based System Design class involved making a simple bang-bang controller. Our embedded system was set up to mimic the typical heater system found within a home. The system was able to increase the heat by running current through a 1⁄4 watt resister. When the heater got above the desired range, the current to the resister would be shut off.

PIC32 Breakout Board

A breakout board created in my Microprocessor Based System Design class for a PIC32 microcontroller. The board was a semester long project in which each student designed a board layout. The class then voted on the layout they liked the most and the winning layout was sent to a board house to have one made for each student. Overview We first breadboarded the basic layout needed to run the PIC32 microcontroller in a previous lab.

Gesture Control Mouse Input

The project for my Sophomore Design class at South Dakota School of Mines & Technology. For our semester long project, my group decided to make a wearable device that could translate hand gestures into mouse input for a computer. We nicknamed the device “The BAND” as an acronym of the involved members first names. Reading Hand Gestures To read the user’s hand position, we used an electromyography (EMG) sensor attached to the forearm with silver coated fabric and conductive gel.
