Fuzzy Logic is my answer to what electrical engineering education could be like.
It's the most intuitive circuit-play kit you can find.
Each plush piece has a socket for an electrical component, and giant magnetic connectors making it easy and fun to build circuits.

Thanks to the Life Long Kindergarden Group at the MIT Media Lab.


I added a waterproof strobe light to my shower.
Now it rains discrete droplets that hover in midair before your eyes.
Tuning the strobe makes the drops flow backwards into the shower head.


I'm welding with a stick welder I made. It's built out of old microwaves.

A friend and I built it together. Here's how you can build one, too!


I made this little robot out of part of an old fiberglass windsurfer mast.
It rolls on velcro tracks on my ceiling and creates abstract line drawings.
I call it "Robjot"


I created this reactor for mixing vaporous ethanol, water, and nitrogen, for the MIT Biomolecular Materials Group.
I gas-tight TIG-welded it out of 3/16" stainless.
The idea is to see if the material we're growing can turn any hydrocarbon (gasoline, ethanol, what-have-you) into hydrogen fuel,
which would eliminate the need for hydrogen refueling stations for the cars of the future.


This is a wind powered battery charger I made while working at Makani Power, a clean wind energy startup.
The propeller provides electricity and charges a set of LiPoly batteries.
I designed the boost converter circuit to convert the low voltage AC input to 12V DC.


I made these powered skates in an afternoon. The next morning, I woke up and found my project on Wired, Make, and Engadget.


Mark Tobenkin and Alex Hornstein play with the 3D blackboard
MIT's Experimental Study Group sponsored me to build, where it's
currently in use as a multivariable calculus instruction tool.

By drawing curves on the three different planes, one can very easily visualize surfaces.

I got the idea after hearing my multivariable professor complain about being
unable to satisfactorily draw 3D shapes on normal blackboards.
Made with a lasercutter.


I put this on my dorm room door so people would know at a glance whether or not I was contained inside.


I made this outdoor fireplace/stove out of an old propane tank, some pickaxes, and an office chair, with Tim Anderson. The instructable is here.

These are two FIRST robots I helped design and build, in high school.

Software

Perspective:
Processing is a fabulous laguage. Here's the first thing I ever made with it:
3D Perspective

Murder:
I wrote a perl script to handle looking up process IDs to give to the unix utility "kill", so I don't have to.
It's a little more subtle than killall, which is why it's useful.
Kill is a hand gun, killall is a grenade, this is hiring a henchman. I call it murder [download].

UpChequer:
Bash scripting! It's delicious! So, my ancient PowerbookG4 crawls, especially after half-year uptimes.
So I wrote this, which, with cron, checks the highest PID on my system every day.
If it's over 10,000, it loudly blasts all my terminals (I always have terminals open) to convince me to
have sympathy and restart my computer.
If you run it, put a message in a text file called 'mesg', in the same directory. chequer [download].
