Taking apart the controls of a scanning electron microscope
Recently my friend Ilan happened upon the control consul for an old scanning electron microscope on reuse. At MIT it is common for people and labs to post stuff to reuse@mit.edu, which means that it is free to whoever wants to take it. The idea is more free stuff and less trash. I don’t know […]

My 5-day go-kart has a name
I will call it SAM, for small automobile. Today a Cambridge police officer took it for a spin! Lot’s of fun.

Correction to Make Blog post
woohoo, I made it to Makezine! Thanks to everyone who came to check out my site! But their caption was only partially true because it confuses 2 of my projects. So just to clarify: I built the go-kart in 5 days, but it uses an off-the-shelf Turnigy motor. However, a few weeks ago I finished […]

Day 5: throttle, batteries, sensors
Proof that everything works: I started yesterday trying to make a throttle. I could have used one of those handlebar hall effect throttles, like what’s on picoFahrrad, but the steering wheel on this one would make mounting such a throttle messy. Also, its just nice to make things yourself. I dug through some bins of […]

Day 5: done.
I actually made my 5 day deadline mostly. First test drive about 3 hours ago. Then I cleaned MITERS (if you have seen MITERS, you know the magnitude of this statement). Just drove it back home from MITERS. details and video to come.

Day 3: now the steering is actually done…
Sorry for the lapse yesterday. Today I am a little behind. Looks like I will have to make a motor mount and seat mount by the end of tomorrow. Yesterday I did most of a steering system, and today I spent a good bit of time fixing it, and then actually finishing it. The steering […]

I swear there was progress today. But I am too tired to post now. Updates tomorrow.

Day 1: Chassis
Today I started on the chassis. I’m going with aluminum, and trying my hand at welding it together. I’ve been practicing aluminum TIG for a few days now, but still just getting the hang of it. I could really use tips, especially on making fillet welds. Here’s a rough CAD model, mostly used to figure […]
