Can the US build a DJI? We bought a 2019 Mavic Mini and a 2023 Mini 4 Pro, tore them down in our hardware lab, and put them under a bench microscope to find out. What we found:

As humans, we don't naturally have strong intuition around electromagnetism so Chris Bryant built a minigame into his blog post on Smith charts to help it click. Give it a try here: What should we demystify next? Let us know in the comments below ⬇️

To build Heaviside, our foundation model for EM, we needed to collect a huge amount of data from traditional FEM simulations of electronic devices. Early on, we ran into a surprisingly basic question: once an FEM solver finishes running its simulation, how do we extract electromagnetic field values from the solution? Here’s Chris Bryant’s interactive explainer on we learned:
