Colors of the Internet
Allison and I had been thinking about decomposing scenes, art, and geometries into representative colors, textures, and features. Then, during an inspiring walk around the MOMA, I spotted a woodblock print (below) by Sherrie Levine. In her prints Meltdown, she decomposes paintings by Duchamp, Kirchner, Mondrian, and Monet into their constituent colors. Can you guess […]

Bitcoin Adventures
I’ve been following the Bitcoin ecosystem for a few years now, and seeing as a coin is now worth well north of 100USD, I decided to finally explore bitcoin wallets and mining under OSX. What are Bitcoins? A lot has been written about Bitcoins over the past weeks as they’ve broken the $100/฿ mark. Without […]

Agilent E3631A Power Supply Accuracy
During the course of my thesis, the need for distraction – plus the need to save some labor inspired me to develop automated testing methods. I wrote a little previously about setting up PyVISA on OSX, but didn’t show any real examples of its use. Here, as a proof of concept, I measure the linearity […]

I Graduated!
It’s been quiet for too long around here… since my last post, my thesis was accepted September 20, 2012 and I received my diploma early February 2012. The title of my thesis was “Low dimensionality spectral sensing for low cost material identification and discrimination”. It really took a lot out of me. I learned a […]

Flying Android Project
In 2009, I was challenged by [govt agency] via GTRI to develop an Unmaned Aerial Vehicle (UAV) which is piloted by a smartphone. In particular, only the sensors on the phone may be used and the flight controller must run on the smartphone. Custom electronics were allowed to interface the phone to the airframe (PHY) […]

RoboCup Electronics Museum
When I flew home to Atlanta over Thanksgiving, I had the opportunity to visit the “RoboJackets RoboCup Electronics Museum”. Really a nice trip down memory lane. I was on the team from its inception in 2007 till I graduated in 2009. I had the opportunity to lead the team from 2007 to 2009 (system design […]

Phased Array RADAR
This IAP I had the opportunity to participate in a phased array RADAR course taught by MIT Lincoln Labs. Our team was named winner (best imagery) by the director of MIT LL, Dr. Eric Evens. I’ll follow up with a more detailed post, until then, click through for a video.

How to Make (almost) Anything
Duplication of my final post for HTMAA. Grand overview of my final project and a few greatest hits. Teaser! Quick preview of my final project, but first some “greatest hits”. I put most of this work in the content repo, the pictures link to the respective project pages. FabISPkey FabISP remixed. I remixed the FabISP […]

T+V
This week, with help from Alex Olwal and Julia Ma, I finally managed to scratch a project itch that has been lingering since the spring. The installation uses crowd sourcing to actively build a tangible visualization of attendee demographics. A world map covered by transparent LEGO baseplates stands at a conference, and bowls of transparent […]

FabISPkey
This semester, I’ve been fortunate enough to take Neil Gershenfeld’s How to Make (Almost) Anything. For one of the first assignments, we’ve been tasked with fabbing (routing on the modella and stuffing) Neil’s FabISP which is based on David Mellis’s FabISP which is based on Limor’s USBTinyISP which is based on Dick Streefland’s USBTiny. I […]

Cypress FX2 on OSX
Getting Ben’s (derivative of David’s) SSRP to work under OSX with modern GNU radio libraries, and have a few notes. To build firmware for FX2 chips – which are 8051 cores, you need SDCC. I got it from MacPorts. sudo port install sdcc To program FX2 parts on Linux, use fxload, a part of the […]

Documentation
I put together a rig to document what runs across my desk, so hopefully more posts in the future! The setup is composed of a Magic Arm attached to an AutoPole with a Super Clamp. The camera I’m using is a Canon A710 IS modified with CHDK. I built a simple USB remote release based […]

Gelatin GRIN Lens
Recently, I’ve been fascinated with flexible optical elements. In particular, I’ve been experimenting with gradient index lenses. Gradient index materials are typically constructed with using semiconductor processes (doping some substrate). In addition, they are typically small both because of their fabrication method and because of chromatic aberrations that are more prevalent at larger sizes. GRIN […]

GNURadio in OSX
After a little effort, I got gnuradio running under OSX with MacPorts. Thankfully, there is a fairly nice package in macports which contains most of the dependencies needed to install everything for gnuradio. Unfortunately, the most recent version of sdcc is not compatible with usrp. So, to install gnuradio, you need to first install an […]

RoboCup
Project Overview For the past three years, I have been the team leader for the Georgia Tech RoboJackets Small Size RoboCup team. RoboCup is an international robotic soccer competition designed to drive research in robotics, multi-agent systems, artificial intelligence and the systems which compose those fields. The stated goal of the RoboCup Federation is to […]

4D Tracker
Introduction There are approximately 515 million cases of malaria every year, of which roughly three million cases are fatal [5]. To combat the spread of malaria, often the carriers (mosquitoes) are targeted. In the past, mosquito larvae have been attacked with varying degrees of success, but sometimes with notable environmental impact (one solution involves flooding […]

SeaWolf
During the Spring and early Summer of 2009 I developed two 10.5 foot long, 325 pound unmanned underwater vehicles (UUVs). My role was technical leader, I oversaw all design of the vehicles. Underwater vehicle construction remains somewhat of a black art where effective design principles are often found through trial and error rather than analytically. […]
