ZDNET's key takeaways The EcoFlow Delta 3 Plus is available now for $899. It's a compact 1,024Wh power station that can connect to external batteries, and its improved cooling mechanism makes it a lot quieter than its predecessor. The silver finish has a tendency to get dinged up. $899 at Amazon Power stations come in all shapes and sizes, but I find that the units on the extreme ends get most of the attention: either the massive ones that can power a home for days or the tiny, ultraportables
THE (UNFINISHED) PDE COFFEE TABLE BOOK Lloyd N. Trefethen and Kristine Embree, editors Unpublished, 2001 During 2000-2001 a group project based in the Oxford University was begun to write this book. The vision was 100 2-page spreads, each one giving exactly the most useful possible starting information about a different partial differential equation, with beautiful color illustrations. Many people at Oxford and around the world contributed drafts, which were then extensively rewritten and e

Characterizing my first attempt at copper-only passives¶ Last year, I kind of got a bee in my bonnet about trying to see if I could accurately (?) make small RF passives out of copper, rather than buying 2pF NP0 capacitors or something, as part of a long-on-the-horizon project to make extremely inexpensive GHz-class oscilloscope probes. I figured that the right place to start was to fab out a board on JLCPCB's JLC04161H-3313 stackup with a handful of calibration standards, and some of the passi
