Motor Vehicle Collision

with 2 comments

On the way to work this morning I watched a cop car T bone a black SUV. I gave a statement to the police and my business card to the driver of the SUV. I’m recording my thoughts here while they’re fresh.

This morning I was walking on the sidewalk at Eastern Parkway and Frankine Avenue in Brooklyn. My location at the time of the collision is represented by the blue circle. My destination was the subway entrance represented by the green circle. I witness a sedan style police car strike the passanger side of a black SUV. The police car’s path is represented by the red arrow. The SUV’s path is represented by the black arrow. The intersection of the red arrow’s tip and black arrow is where the collision took place.

I did not observe the state of the traffic light. However, I was paying attention to the crosswalk signal represented by the yellow circle. At the time of the collision there was an amber blinking hand. After the collision I continued walking across the street, keeping an eye on the cars while mentally processing what happened and deciding if I should stick around. As I made it across Franklin Avenue to the crosswalk signal I observed that the signal was still blinking. The crosswalk signal is significant because it indicates the SUV had a green light at the time of the collision.

I did not hear the police car siren, but I couldn’t say with certainty that it was not on. I’m fairly confident that the siren was off and a few blips were sounded just before entering the intersection. I can say with certainty that the police car did not slow down enough to ensure the intersection was clear. Also, the SUV was traveling at a normal speed when entering the intersection.

MakerBot Replicator Launched

with one comment

Today I’m very proud to announce the MakerBot Replicator is launched. We started development this summer with two full time employees, a college intern and a hand full of high school students. Developing a new product from idea to launch was a huge undertaking, but we knew we could do anything. Over the past months the team grew, but the goal remained the same: create the ultimate dual material 3D printer for your desktop.

Cardboard Surfboard

with 9 comments

Wow! Thingiverse citizen Mike Sheldrake has posted a totally awesome cardboard surfboard.

I’ve been making and riding cardboard-core surfboards for about three years now. They work. Leaks are not the huge problem you would expect. And they happen to look – what’s that old term the surfers used to use – awesome!

The design files come lain out in 12×24 inch sheets meaning it can be cut on the NYC Resistor laser cutter.

UPDATE: The surfboard was covered by Becky Stern back in June of 2009.

McMaster-Carr has 3D Models

with 4 comments

Every product you see was designed. Most of these were designed using three-dimensional CAD tools. This means that most of the things we use already have 3D models somewhere out there. Thingiverse is a great place to share the objects you have created and download the objects shared by others. But what about all the things not on Thingiverse? McMaster-Carr is full of 3D models for various parts. Do you know of any others?

Skeinforge Trick: Extra Base Shells

leave a comment »

Colorbroken used a a neat Skeinforge trick to get a concentric patter on the bottom of this 120 Film Advance Crank. All he had to do was increase the “Extra Shells on Base Layer” in the Fill pane. Can you can count the rings to calculate how old it is? :)
