I heard a top aerospace engineer say that it was uncanny how every single time the planes that look the coolest actually fly the best and have the best performance. Hard to say why that is but it encourages me to make all my engineering designs as sleek and beautiful as

So apparently while doing a teardown of the Unitree Go2 robot dog iFixit found a GPS module inside that is not listed in the official spec sheet for the robot. The robot also has a camera and microphone along with lidar. So you are trusting this company with geotagged video,

I never noticed the McMaster catalog in Big Hero 6 before. The Disney Animation people pay more attention to details than I realized.

Here is Lecture 3 of my class Advanced Machining at MIT. This class covered machining different kinds of materials and goes over which types of machines are best for working with various materials. The guest lecture was given by Sean Rescsanski (@srescs) and covered other

If a startup can make their own supersonic jet engine, I’m really not sure we should say that anything is out of the question. Be bold!

I want to share an update to this post: some very thorough folks here on X have correctly pointed out that this module is actually an LTE module and not a dedicated GPS module. The specs do explicitly mention an LTE card onboard. This LTE module does have a GNSS engine and is

Replying to @chbigelow
I know probably 4-5 people at this level of competency in the world. Each one of them amazes me and sets the bar to which I aspire to reach one day. I think there’s a common misconception that if you spend your time getting better at all of these things at the same time that

Here’s the course description: “Advanced Machining will go over detailed and in-depth knowledge related to practical subtractive manufacturing (machining material away rather than additive manufacturing like 3D printing). For each session, the first half will be a lecture that
