Introduction Our project measures the user’s skin conductance for monitoring his or her mental state. Summary Medical experiments have shown that the magnitude of the electrical conductance in a person’s skin is directly correlated to their emotional state. The short term changes in electrical conductances also correlate with a person’s mental response. We implemented an […]

When we think of programmable speech recognition, we think of calling FedEx customer service call center with automated voice recognition response systems. We also think of PC-based speech recognition Dragon NaturallySpeaking. Now we took that a step further. We are talking about speech recognition in a tiny Mega32 microcontroller. We are talking about real-time speech

Introduction Overview SecureLED is an optical access control device which replaces current RFID or Magnetic Strip technologies with a cryptographically secure, contact-less device which communicates over commodity Light Emitting Diodes (LEDs). Project Summary This project started with one central premise: current physical access control systems are insecure in fundamental ways. We sought a way to

Introduction The objective of this project was to build a keyboard based on capacitive sensors and then use the MCU to create MIDI encodings for all notes played. The output from the sensors is detected by the MCU using its ADC capability. The sound is played directly by the MCU via a piezo speaker using

Introduction: One Sentence Sound Byte: “Grillzilla – A wireless meat grilling thermometer which alerts the user whether their entrée is cooked according to USDA recommendations via LCD and voice feedback.” Summary of what we did: As the weather starts to get warmer a common type of social gathering that occurs is the barbeque. Barbeques are

Introduction Objective The goal of this project is to design a useful and fully functional real-world product that efficiently translates the movement of the fingers into the American Sign Language. Background The American Sign Language (ASL) is a visual language based on hand gestures. It has been well-developed by the deaf community over the past

Introduction We developed a new way for student groups to chalk advertisements for events. This project is a radial printing device for drawing with chalk/markers on flat surfaces. High-Level Design dea Rationale and Sources Anyone who has done any sidewalk chalking knows that it is one of the few tasks that humans were not designed

Introduction This project is a bicycle computer that includes velocity monitoring, calorie computation, an audio/visual alarm, and a wireless remote. Bicycles are great for transportation as well as exercise. Unfortunately, many bicycles across campus and around the world are stolen everyday. We designed a computer that would deter someone from stealing the bicycle while also

I. Introduction Simply write; your computer will undersand! We have designed and implemented a Handwriting Recognition System using a touch screen from a Palm Pilot m125, a black and white TV and a Mega32 microcontroller. Unfortunately, due to the lack of specifications regarding the built-in LCD on the Palm Pilot, we were unable to reverse

Introduction The goal of our project was to develop a remote control whose buttons would be readily programmable by recording the signal from another remote control. After revising several standards on infrared signals, we determined that the approach to take was to record the signal by determining the width of the transitions in the waveform,
