Elizabeth Case is back for the holidays to talk about how she went about building a custom drone for her graduate work, the lessons she learn, and the problems she encountered. She and David Bryant have a great dialog about tools, 3D printing, software, controller types, and other drone-related issues. Elizabeth is now an FAA-licensed drone pilot and talks about interesting uses for drones in science. If you’re at all interested in building your own drone, give us a listen.…Continue reading Build Your Own Drone
I recently attended part of the RISC-V workshop at the Google campus. RISC-V is a fully open source CPU instruction set developed at UC Berkeley developed by Krste Asanovic, Andrew Waterman, and Yunsup Lee.

More appropriately, can SiFive compete against smaller, agile proprietary players like Andes Technology, Synopsys, and Cortus? Unlike…Continue reading Can Open Source Processors Thrive?
A Medium post by Arlo Gilbert about Google’s decision to shut down the Revolv home automation hub went viral recently. Google’s Nest division bought Revolv 18 months prior.

It’s one thing when a service goes offline, but another thing completely when a product associated with…Continue reading The Ugly Side of Always On
