This book has its genesis in the author’s wildly popular (and oft-downloaded) papers, “An Elementary View of Maxwell’s Displacement Current„ and “The Fundamentals of Electromagnetic Theory Revisited,” published in this Magazine in February 2008 and November 2009, respectively. In these works, Dr. Arthur discussed the many misunderstandings that arise in the standard presentation of electromagnetic theory, which uses Oliver Heaviside’s now-familiar notation for Maxwell’s equations based on Josiah Willard Gibbs’s vector notation. In particular, that work lamented the common depiction of magnetic quantities B and H, including their relationship with one another, their nature as fundamental or derived fields, and their importance for the theory of special relativity.

Yesterday I posted this on Mastodon (post link) I'm building a new habit here on Mastodon: instead of liking, I try to reply to at least 3 posts, especially...

So we're using an ESP32S with a TJA1050 transceiver and basically we're using this setup to operate a rover using ROS2 Humble and MAVLink commands, so it has a lot of modules like actuators, PDB, mini-arm, and etc connected through a CAN bus network. Now the issue is that we will be using multiple BLDCs for our rover's arm and these motors continuously send out updates (or heartbeats or sth) so using these BLDCs in the same network seems like the MCU will lag or slow down and just be downright ineffective. So is there any way to isolate the motors to a different network or CAN line? I was thinking of adding another MCU on top of the ESP32 to only handle the motors but is there an alternative to this approach, preferably one without adding more hardware? submitted by /u/Sadhya [link] [Kommentare]
