#ECEB SUBMETERING

Our RFA is based on Prof. Schuh’s proposal for a 3-phase, 208V, 60Hz power meters that can be placed inside individual rooms for detailed power monitoring.

#PROBLEM
The ECEB is notably a net-zero energy facility, which is possible due to utilization of energy efficient methods such as the use of solar panels. We would like to be able to measure and share data collected from the energy generated by the solar panels in order to help track the efficiency and use of energy of the ECEB building. With regard to the ECEB submeter of previous semesters, we would like to improve upon the accuracy of the data recorded to yield more practical and useful results.

#SOLUTION
Our solution is to create power meters that can accurately measure power, voltage, and current of individual rooms within ECEB and be able to accurately get and store these data metrics as well as being able to display them to either an LCD or the TVs within the ECEB. We plan to improve upon many of the shortcomings the previous implementation faced.


#SOLUTION COMPONENTS
##Subsystem 1: Power System
This system is required for powering the IC's, microcontroller, and LCD along with any other components of our project.

Chargeable Battery (5 to 10V)
Linear Regulator (Buck Convertor) MC34063AP

##Subsystem 2: Sensor/Electricity measurements
This system will allow the received AC signals to be changed into DC digital signals that the microcontroller can interact with.

ADC converters for current and voltage MCP3008-I/P
Voltage Transformer
Voltage Divider Circuit
Voltage Pull Up
Current Transformer CTF-5RL-0400
Current Divider Circuit
Current Pull Up

##Subsystem 3: Storing Information
Our design intends to store information offline onto a SD card and onto an online server
Microcontroller to Display and data recording System:
ESP32 Microcontroller used to transmit recorded data offline to SD card and to online server.
SD card module to interface SD card and ESP32
SD card to store data on
A cost effective online server or database to store our data

##Subsystem 4: Visual display of our data
This system allows us to display our data onto a screen to display to the viewer.

Usbc to HDMI to display information on a TV
LCD screen to display data onto

#CRITERION FOR SUCCESS
Be able to store our data offline on to SD card along with the date and time
Be able to upload our data online every 15 minutes via wifi
Be able to display data and waveform on LCD or TV
Be able to measure Voltage, Current, Power, and other key data metrics (Power Factor, etc.)

VoxBox Robo-Drummer

Featured Project

Our group proposes to create robot drummer which would respond to human voice "beatboxing" input, via conventional dynamic microphone, and translate the input into the corresponding drum hit performance. For example, if the human user issues a bass-kick voice sound, the robot will recognize it and strike the bass drum; and likewise for the hi-hat/snare and clap. Our design will minimally cover 3 different drum hit types (bass hit, snare hit, clap hit), and respond with minimal latency.

This would involve amplifying the analog signal (as dynamic mics drive fairly low gain signals), which would be sampled by a dsPIC33F DSP/MCU (or comparable chipset), and processed for trigger event recognition. This entails applying Short-Time Fourier Transform analysis to provide spectral content data to our event detection algorithm (i.e. recognizing the "control" signal from the human user). The MCU functionality of the dsPIC33F would be used for relaying the trigger commands to the actuator circuits controlling the robot.

The robot in question would be small; about the size of ventriloquist dummy. The "drum set" would be scaled accordingly (think pots and pans, like a child would play with). Actuators would likely be based on solenoids, as opposed to motors.

Beyond these minimal capabilities, we would add analog prefiltering of the input audio signal, and amplification of the drum hits, as bonus features if the development and implementation process goes better than expected.
