Katerina Galitskaya is a Senior Antenna Engineer who is currently designing base station antennas. She joins Chris to talk about simulating, visualizing, and thinking about the design of antennas. Listen for everyday design rules and stories of interesting antenna designs.
This week Dave and Chris talk about Meshtastic (a meshing layer on top of LoRa), new scope specs, cellular modems, power, and a new Embedded Conference in the US.
Dave and Chris record together after a long hiatus because Chris spent the summer moving boxes between two houses and reorganizing his lab. Also hardware livestreams, open source hardware, new battery storage, layoffs, and more!
Shawn Hymel is an engineer and content creator who recently left his developer relations job at Edge Impulse to work on developing courses full time
Dave and Chris return to talk electronics trade shows, API tools, solar and batteries, automation, and more!
Bitluni joins Chris on The Amp Hour to discuss FPGAs, ESP32 projects, custom silicon, building around memes, and continually challenging yourself to learn something new.
Matt Venn returns to The Amp Hour to talk about the successes (and learnings) from many additional runs of TinyTapeout, a shared project service sitting on top of a multi product wafer service. Matt also talks about a forthcoming analog ASIC design class on Zero to Asic, his online course.
Dave and Chris talk about the letdown of signing an NDA and seeing "behind the curtain". Also inverters, programming tools, pricing changes at Altium, and old school web stuff.
Chris joins the Circuit Break podcast (Parker Dillman, Stephen Kraig) along with James Lewis to talk about engineering careers. This show will also be posted as episode 435 of the Circuit Break Podcast

Superconductors 100.5 (I'm not wise enough to do a 101): Superconductors have a critical current (or magnetic field) above which they lose their superconducting property. The max current tends to increase as the temperature drops. Opinion: SCs, even if we get them working above room temperature, will never be cheap enough for widespread use just to power chips, or cars, ot homes.

Framework laptop would suit me, because I'm a cheapskate and I want to reduce wastage. I think the modules connect via internal USB Type-C, so the Type-C module is just a port saver. Imagine giving a live coding conference talk and finding they can only take Apple iThing connections. Easy. Open your "Joe 90" briefcase, grab the iThing connector module and stick it in where the other video output module was. A bit neater than carrying adaptor cables. And laptops are getting harder to repair/upgrade, while Framework reverses that. My current portable is still a old and beaten-up Lenovo laptop (Flex 14" 20404). Fitted maximum RAM and a big SSD. I only write code and assemble/compile and it's fast enough, so I'll look again at Framework when old faithful can't cope any more. My old Lenovo is easily repairable for battery, screen, keyboard, RAM, fan, connectors. I'm not so sure about newer stuff, so if I buy a Framework, maybe it's a vote, as well as making repair easy?

There was a chip released that I called an "Erg Thief". I got the release though the post (don't know why--I'm a semi-retired programmer who drives buses!). Anyway, it reckoned to run from about 0.4V, needing (from memory) 1.2V to start. The sheet listed charging from a single solar cell as an example. So, for moon power you need a lower PV cell voltage to reduce the leakage. 0.2 or maybe even lower? This chip could power your quartz clock from the Moon. Gotta be worth it :-)
