Arduino and Django Data Logger August 17, 2013 No Comments

In an effort to demonstrate a new django-quick-start package I’m making at work (similar in purpose to pinax, but with some SpaceX-specific packages), I decided to create an Arduino data logger that is viewable through Django. The data from a couple different sensors is first collected with an Arduino. A Python daemon polls the Arduino [...]

Mecanumbot Integrated Lights Test April 9, 2013 No Comments

I’ve finally achieved end-to-end control of the Mecanumbot’s LEDs! The latest hurdle which prevented me from writing the LED code was a RAM limitation on the microcontroller side. The solution involved swapping over from an Arduino Duemilanove with 1KB of RAM to a Seeeduino Mega with 8KB of RAM. The increased RAM also opens the door for me [...]

Automatic Daily Fish Food Dispenser November 23, 2012 No Comments

Meet Bob, the goldfish (pictured below.) Bob is a pet at work, and we needed to keep him fed over the Thanksgiving break. I had an Arduino and a servo that were free, so I wanted to make something that would supply him with the right amount of food for the four days we would [...]

Legorov Teleoperating Robot November 8, 2012 2 Comments

I built this little robot out of Lego this week (see picture.) The electronics include an Arduino, a Sparkfun xBee shield, and an Adafruit motor shield. On the other side of the xBee shield is a linux box running ROS. With ROS I can generated velocity messages from my keyboard or with a Wiimote. These [...]

Mecanumbot Motor Testing July 28, 2012 2 Comments

This passed week I have been playing with the new motors and motor drivers I got for the Mecanumbot. I used some MicroRAX pieces and the supplied motor brackets to piece everything today. I controlled the MD25 motor controllers over I2C using an Arduino which was getting commands from an RC transmitter. Unfortunately the naive [...]

Starting New Project: The Mecanumbot July 20, 2012 No Comments

Alright. I have decided that I do not have the time or desire to figure out the controls problems that the Ball Bot presents. I really am interested in the navigation and localization challenges that I can work on with a functioning robotic platform. So what I need is a platform that is easy and [...]

Serial7 Arduino Library February 13, 2012 No Comments

I wrote an Arduino library for SparkFun’s serial 7-segment displays and figured others might find it useful. It essentially takes care of outputting a number over serial including shifting around the decimal point. A zip file of the library is available below. Here is the contents of the library readme file: This library is designed [...]

SpaceX Microcontroller Class February 10, 2012 No Comments

I taught a microcontroller class to a few people at work this week. The goal of the class was to show people how easy it is to interface hardware and software with an Arduino. Each participant was given a little project to complete by the end of the day. The first half of the class [...]

The Ball Bot May 4, 2011 No Comments

I’ve started a new robot project! This will be one of the most challenges personal projects I’ve embarked on. I have the following goals: designed to be a flexible software test platform mechanical design from scratch in SolidWorks, manufactured from G10 low level control through off-the-shelve electronics including an Arduino, SparkFun Quadstepper motor controller, ITG-3200 [...]

Scalable Advisory System for Structural Health December 12, 2010 No Comments

Woo! We finished our senior project. We have created a system of wireless accelerometers to measure the structural health of buildings. See below for some pictures and downloads. Abstract: A Structural Health Monitoring (SHM) System, relying on identification of changes to a structures resonant frequency to recognize potential structural damage and provide alerts, is designed [...]
