39 Photocell Music Board based on Eli Fieldsteel’s Project Pitch

Our project involves creating an improved version of Eli Fieldsteel’s prototype music board. The music board consists of an array of 256 photoresistors connected via USB to a computer. The computer runs a program written in the Supercollider programming language to collect and interpret data from the music board. Each photoresistor detects the intensity of light shining on it. When a drop in light intensity on a photoresistor is detected, the computer plays a note. The music board is capable of playing any combination of notes simultaneously.

The improved music board will feature modular photoresistor boards and execute internal component failure checks. 256 photoresistors will be placed on 16 identical PCBs with 16 photoresistors on each board. If a photoresistor fails, a single PCB can be replaced easily without affecting the rest of the music board.

To add to Eli’s original design, we will also implement:
A 16x16 LED display board that will mirror the hand motions to provide a matching visual for demonstration purposes.
An algorithm to smooth the data to account for effects of inconsistent light sources including interference from spotlights and low light environments.
A user interface to switch between multiple instrument sounds and adjust board characteristics (pitch, volume, sensitivity, calibration)

Additional Ideas:
Create a generic design that can use different types of sensors (touch sensors, flex sensors, distance sensors, color sensors)
Design a small, hand held, self contained version with battery power

Cypress Robot Kit

Featured Project

Cypress is looking to develop a robotic kit with the purpose of interesting the maker community in the PSOC and its potential. We will be developing a shield that will attach to a PSoC board that will interface to our motors and sensors. To make the shield, we will design our own PCB that will mount on the PSoC directly. The end product will be a remote controlled rover-like robot (through bluetooth) with sensors to achieve line following and obstacle avoidance.

The modules that we will implement:

- Motor Control: H-bridge and PWM control

- Bluetooth Control: Serial communication with PSoC BLE Module, and phone application

- Line Following System: IR sensors

- Obstacle Avoidance System: Ultrasonic sensor

Cypress wishes to use as many off-the-shelf products as possible in order to achieve a “kit-able” design for hobbyists. Building the robot will be a plug-and-play experience so that users can focus on exploring the capabilities of the PSoC.

Our robot will offer three modes which can be toggled through the app: a line following mode, an obstacle-avoiding mode, and a manual-control mode. In the manual-control mode, one will be able to control the motors with the app. In autonomous modes, the robot will be controlled based off of the input from the sensors.
