- Quartus II
- Chris is working with a Mech E who can iterate on very detailed designs using resin. Dave has torn down a resin printer (SLA)
- Dave had a 121GW prototype made from Resin
- Digikey printing on the tape
- Make your own parts kit
- Paper about thermoelectric generators
- These are much much lower output than an RTG, because the input power source is so much lower
- Video by Anton Petrov, Dave did a response video.
- Chris is interested in a new solar MPPT and battery charging chip, BQ25798
- Energy harvesting chip turn on requirements
- Solar panels
- When should you architect your whole system (write all the code) from scratch?
- Dave’s new ATEM switcher has a lot of customized code, not just drivers (maybe a custom OS?)
- Buying IP
- Speaking of developing an OS, Bell Labs just released Plan 9, including a Raspberry Pi image. The name is drawn from the terrible Plan 9 from Outer Space movie. Chris used to watch terrible movies like this. The one he tried to remember was “Invasion of the Saucer Men”
- A self-study plan posted on Hacker News
- Buy a kit for the area you’re interested in (in the above case, a brain interface kit)
- Don’t have a starting project? Chris recommends you follow past guest Ben Eater’s videos and follow along with a kit.
- Chris and Dave both like the PCBite system
- Intel announced they’re expanding their foundry capabilities. Chris predicts they will be spinning out the chip side soon (as a different company)
- TSMC is planning to build in Arizona for $35B
- Texas Fabs shut down from the power outages. NXP is just now recovering.

Hi! Commenting here as I don’t have twitters or reddits.
When there’s talk about electronics books I haven’t heard the free series “Lessons In Electric Circuits” by Tony R. Kuphaldt being mentioned that often. I think they’re great for absolute beginners. Helped me when going through my electrician studies here in northern EU. I’m not a native English speaker so by electrician I mean that person who wrangles those very angry pixies that seem to be coming out of the wall. The books are available here: https://www.ibiblio.org/kuphaldt/electricCircuits/ DC, AC, SEMI, DIGI, REFerence and EXPeriments
Tony has also published a book called “Lessons In Industrial Instrumentation” which is over 1000 pages. It has a lot of the stuff from the earlier books and a lot more. Has a primer on calculus as well as the material is considered for level above the vocational. That book is available for free here: https://www.ibiblio.org/kuphaldt/socratic/sinst/
Also one book that is not free but is really amazing value for money is this next one. It’s not strictly an electronicals book but rather a wide view of the whole EE thing. I think it is because EE’s tend to be curious people and want to know what/how the pixies are doing behind the wall and underground etc.

samples: https://www.europa-lehrmittel.de/downloads-leseproben/30337-2/110.pdf
I included links to the sample pages of the two above as imho those are some of the best textbooks that I have ever bought in terms of visual presentation.
