Far and away my most ambitious project to date, this digital oscilloscope can sample up to four channels at a rate up to 100kHz. And the best part? It only cost me about $40 in components. The user interface is an application running on a PC. The user selects the configuration settings here. When the […]

Introduction In our final project, we have built a multi-functional car controlled by a web application on the PC, which allows users to drive the car as well as play music from the interface on the website. All the requests from the website are collected by JavaScript and the runtime environment Node.js serves to transmit the command via Bluetooth

Introduction In this project, I have created a musical synthesizer with the ability to generate realistic instrumental sounds and to record songs for playback with harmonization. Controlled by a PIC32 microcontroller, the synthesizer has over a full octave of buttons, laid out like a piano, to allow playing notes and making chords. It combines additive

description This is my electronic combination lock to use with an outdoor gate. The functionality is implemented in software. It turns on a relay (usually to open a door) for a few seconds if someone enters the valid code. Alternatively, it works as an ON/OFF switch, which toggles the relay each time the code is

Introduction The Happy Little Mixer is an automatic ink mixer which accepts a hex user input and creates that color by measuring out cyan, magenta, yellow, and black (CMYK) ink. It includes open-loop feedback using a color sensor to correct the generated color, making it as accurate as possible. High Level Design We wanted to

Design Goal: The JavaBot1 is a small line following robot designed to follow a black line drawn on a dry erase board. It is designed to follow very tight curves. The software still has lot’s of room for improvement but works well as is. Motive Power: The JavaBot1 uses 2 Cirrus CS-70 servos that have
