Engineering creativity comes to life when you have to design around a set of constraints. We can do just about anything with enough time, talent, and treasure, but what can you do when shackled with limitations? Some of the most creative electronic manufacturing tricks spring to life when designing conference badges, as the ability to […]
It’s time once again for another installment in “Milspec Teardown”, where we get to see what Uncle Sam spends all those defense dollars on. Battle hardened pieces of kit are always a fascinating look at what can be accomplished if money is truly no object. When engineers are given a list of requirements and effectively […]
Join us on Wednesday, August 21st at noon Pacific for the Life at JPL Hack Chat with Arko! There’s a reason why people use “rocket science” as a metaphor for things that are hard to do. Getting stuff from here to there when there is a billion miles away and across a hostile environment of […]
To the surprise of nobody with the slightest bit of technical intuition or just plain common sense, the world’s first solar roadway has proven to be a complete failure. The road, covering one lane and stretching all of 1,000 meters across the Normandy countryside, was installed in 2016 to great fanfare and with the goal […]
