Code Hero funded!
I've been pitching Code Hero to people around me since I ran across it on Kickstarter, but I hadn't been very confident that it would get funded. They did it! They posted about half an hour ago when they...

IAP 2012 Recap
What I actually did: Run two phenomenal events (in one weekend, no less): Battlecode and Techfair. This really did take huge toll on me: for almost 75% of IAP, I felt that I had little to no time for myself because of all the work I needed to do and that every task was incredibly time-sensitive, wh...

Things getting done: The beginning of Big Motor
I unfortunately have other things to do than post on the internet but I feel obligated to update this every once in a while so for the maybe one or two people who stumble here by accident so please sit down and enjoy the beginnings of Big Motor (the motor that will supersede smal...

Sightless Construction!
Build instructions and schematics for construction of the Braille-It labeler will be released as open-source materials later this year. As a preview, I am posting a sample set of build instructions to the Sightless Construction page of this site. The Embossing-Pin Shaping Instructions [link] detail...

Electric Razor: Construction
So I kind of never made a post on the machining and construction of the rest of the scooter (other than the motor), even though it came (chronologically) before the motor testing. Instead of making a bunch of separate posts, I am just going to dump it all here in one post. The scooter body [...]...

21w.789 lecture two notes
http://web.mit.edu/21w.789/www/syllabus12.htmlWays we screwed up: Didn't agree on research questions beforehand so when we talked to people in parallel fashion, we explored different topics (yay data that's hard to affinity group), e.g. one of us talked to people about how they share projects,...

3ph v4.0
I've finally nailed down working Sensorless Sine-Commutated Field-Oriented Current Control (SSCFOCC) for Pneu Scooter, and I promise I will write up this (relatively) simple algorithm sometime soon before moving on to more complex closed-loop observers and other controls-y things that won't be of mu...

VU Meter – First Audio Test
The VU Meter works and has more or less been validated. I need to make a few more measurements but I’m fairly confident in the circuit at this point. Next step is to add a peak detector to the input … Continue reading →...

Things That Are Entertaining :P
Term started (booooo) but I'm pretty excited about classes :D I get to take another lab class from my favorite professor so far, Steve Leeb, but this time on microcontrollers (6.115). I've had some experience with Atmel products, but only at a high level. Most of it was attempting to write C/develop...

Woodcart update
I started this project with my neighbors at the end of August, now already more than 3 months have passed. Progress has been slow, but pretty steady. We’ve met to work on it for 1-2 hours on 60-70% of the weekends so far. So, in all there’s been maybe 15-ish hours of work. The first [...

What’s it like behind the Great Firewall?
If you’ve talked about going to China, you’ve talked about the Great Firewall.  I talk and think about it so often — every day when I need to connect to the internet — that I can’t even remember how much of the cultural consciousness it occupies in the US. But I remember wonde...

A New Beginning
Things this semester are going to work a little differently than usual. First, whereas in previous springs I had just wandered into the Pappalardo undergraduate teaching lab to check on and occasionally advise mechanical engineering sophomores in the 2.007 design class (to atone for my sins), this t...
