Chris and Elecia apologize, discuss uses and abuses of chatbots, reach out to an uncertain manager, try to help someone out of their professor's draconian rules, and extol the joys of reading. 
Chabot Space & Science Center is in Oakland, CA, US. It is wonderful!

Hang in there! You are probably doing better than you think.

Audio books are great! In the US, many libraries have digital libraries with extensive audio collections. There are several apps with different catalogs for the same library Libby, Kanopy, Hoopla, and Palace (check out the California shelf at Palace!).
And since you are probably going to ask about the games Elecia doesn't play:
Turing Complete shows how logic and logic gates work, building up a processor.

Zachtronics' TIS-100 is another logic and processor design game. It is a little ugly in spots (too real world) but it is a really deep dive into learning assembly. It is the precursor to Shenzhen IO but harder to finish.

Zachtronics' Shenzhen IO is about circuits and how they work .

Human Resource Machine by Tomorrow Corporation is about optimizing resources, it turns out to be a lot like assembly programming.

Should you have gotten here because you wanted facts about teeth, Elecia had been enjoying Bite: An Incisive History of Teeth, from Hagfish to Humans.

Mark Omo and James Rowley spoke with us about safecracking, security, and the ethics of doing a bad job.
Mark and James gave an excellent talk on the development of their safecracking tools at DEF CON 33: Cash, Drugs, and Guns: Why Your Safes Aren't Safe. It included a section of interaction involving the lock maker's lawyers bullying them and how the Electronic Frontier Foundation (EFF) has a Coders' Rights Project to support security research.
As mentioned in the show, the US Cyber Trust Mark baseline has a very straightforward checklist; NISTIR 8259 is the overall standard, NISTIR 8259A is the technical checklist, NISTIR 8259B is the non-technical (process/maintenance) checklist. Roughly the process is NISTIR 8259 -> Plan/Guidance; NISTIR 8259A -> Build; NISTIR 8259B -> Support.
We discussed ETSI EN 303 645 V3.1.3 (2024-09) Cyber Security for Consumer Internet of Things: Baseline Requirement and the EU's CRA: Cyber Resilience Act which requires manufacturers to implement security by design, have security by default, provide free security updates, and protect confidentiality. See more here: How to prepare for the Cyber Resilience Act (CRA): A guide for manufacturers.
We didn't mention Ghidra in the show specifically, but it is a tool for reverse engineering software: given a binary image, what was the code?
Some of the safecracking was helped by the lock maker using the same processor in the PS4 which has many people looking to crack it. See fail0verflow :: PS4 Aux Hax 1: Intro & Aeolia for an introduction. 
Mark and James have presented multiple times at Hardwear.io, a series of conferences and webinars about security (not wearables). Some related highlights:
2024: Breaking Into Chips By Reading The Datasheet is about the exploit developed for the older lock version on the safes discussed in the show.

USA 2025: Extracting Protected Flash With STM32-TraceRip is about STM32 exploits.

James Cameron spoke with us about programming for and operating a large telescope. The show is a blend of astronomy, engineering on the fly, and weird lady bug habitats. 
The Anglo-Australian Telescope (AAT) is part of the Australian National University's Siding Spring Observatory in Coonabarabran, New South Wales, Australia. 
The AAT has an all sky camera where you can check in on a very dark sky. 
James was on Embedded Episode 172: Tell Forth You Me Please where we talked about the Forth programming language and his experiences with One Laptop Per Child.

Unrelated to the AAT, Chris took this image of the Andromeda Galaxy (M31) from his Zwo Seestar 50 over 9 hours (multiple days), stacking the images and processing the data.

Nathan Jones and Chris Svec give Chris and Elecia their 2025 performance review. 
Donations went to Elevate Tutoring, an organization that provides funding and support to low-income and first-generation college students as well as free STEM tutoring for underserved schools.  Embedded has already sent in the match to the donations for a total of over $5000. 
Here is a list of all Embedded.fm episodes.
We mentioned the Foldscope, a small but mighty microscope. Also, mentioned was the book If I Only Changed the Software, Why is the Phone on Fire?

Sophi Kravitz joined us to talk about art, science, and engineering. 
You can see Messages from Space on Sophi's website /sophikravitz.com). A subset of the artwork had a short stay for a demo at Chabot Space & Science Center. The completed work will be shown in 2026. Sophi mentioned collaborating with two sonic environment artists Sofy Yuditskaya and Ria Rajan.
Geiger–Müller tube is an ionizing radiation detector. Cosmic rays move through space at nearly the speed of light, generally originating far away and long ago. You can also see them in a cloud chamber, like the one at San Francisco's Exploratorium. We also talked about using sculpting in Blender (there are many online video introductions).
Sophi does EE consulting and system quality checking at her company Greenlight.
