My work, on display at NAB

It’s not unusual for a product or service that I played some small part in designing and building to appear at an industry trade show, whether that’s CES or NAB or whathaveyou. But this year, a device in which I was a lot more integral in the hands-on design and manufacture appeared. I not only designed a … Continue reading My work, on display at NAB

On equality, with a digression into toys

I am going to get serious for a few paragraphs, but don’t worry. It will lighten up and there will be cats. Today, in the United States, is Martin Luther King Jr. Day. It is a federal holiday celebrating the life and work of MLK Jr. The world has changed significantly since the 60s — … Continue reading On equality, with a digression into toys

Further adventures in OpenGL: Octocat

As a followup from my previous OpenGL post: I have now successfully rendered an external STL file (a 3D printer object) using OpenGL. And what better model than the Octocat? Warning: nerd talk ahead. Stop reading if you don’t care about the nerdy details. It turns out that I can’t de-dupe the points as I … Continue reading Further adventures in OpenGL: Octocat

Unless you’re doing game development or scientific visualizations, you typically don’t need to mess with it. (And even game developers frequently use higher-level tools to hide the picky … Continue reading Experiments in OpenGL

Hex math cheat sheet

I do a lot of design work for 3D printing (see also: the MakerBot category on this blog). For some reason, I keep finding myself repeatedly doing a lot of math related to hexagons and the triangles that compose them. The first few times, I did the trigonometry by hand. Over time, I offloaded that to Google … Continue reading Hex math cheat sheet

On 3D Printing Lego Robot Accessories

This past week, the engineering department of my company (Elemental Technologies — we’re hiring engineers, by the way) had our annual off-site. This year we did something a little different and had a Lego competition. The previous week, we were given time with the Lego Mindstorms kits to get familiar with the components and programming language. The … Continue reading On 3D Printing Lego Robot Accessories

3D Printed Medieval Barbie Armor

Zheng3’s Kickstarter project is to design 3D printable medieval armor for Barbie dolls. I see this as being a great transition to help girls ease their doll play from “let’s go shopping” to a much more active and kick-ass “let’s fight that nasty dragon and save the village.”
