- Dave once designed PCBs over remote desktop
- Chris had to do remote chip design in college…while trying to learn Unix at the same time
- “The Best Software of PCB Design EVER” on the EEVblog forum
- Educational curriculum laziness (not wanting to make new content). We discussed this a little with Brock Lameres when he as on the show.
- CU Boulder has an IIOT learning track that looks interesting. But is it worth $500 per class? Maybe!
- Sydney / Dublin / Washington accord

- We had a question on our subreddit about whether we get overwhelmed by learning electronics
- App note about MPPT on the BQ25895
- Past guest Dave Young has made a dev board for Voltaic that has built in MPPT directly on the charge controller chip (BQ24650)
- A DIY VNA that can go up to 6 GHz! (Chris stated the low cost VNAs can’t go past 1 GHz, which it turns out isn’t true)

The CMOs inverter 4040 as an analog element, there is a very famous synthesizer built around that. The EDP wasp, this one is from england around the 80s. Back than i think the designer used 4040 because they were available and cheap.

For those interested there is also a jasper clone out there a diy kit, since back in the the 80 all music as well as other companies simply have been open source by design (all schematics available for servicability) people nowadays can simply clone the old product 1:1
I think you meant the 4069UB inverter – 4040 is a counter.
By the way, I would love to see an EEVBlog video about circuits based on unbuffered CMOS gates.
There are some clever ways to use them, like https://www.edn.com/cmos-hex-inverter-generates-low-distortion-sine-waves/ and https://www.edn.com/single-hex-inverter-ic-makes-four-test-gadgets/
They are also a good match for crystal oscillators: https://www.onsemi.com/pub/Collateral/AND8141-D.PDF
Old software:
Coworker has a laptop dedicated to old Protel layouts. We still get requests for board changes and it all still works.
Hacks:
Company called Maxima uses a ripple counter for their hour meters. You’ll find them in John Deer and other such equipment. The design depends on a race condition which only works with Texas Instruments parts from a certain factory. Joke of a product and company.
Universities and accreditation:
I earned a bachelors from an ABET accredited school (DeVry), but based on the school’s name alone, many companies refused to acknowledge it. They’d say “We’re really looking for someone with a ‘full’ or ‘traditional’ degree, instead of a ‘night-school’ program”. Some would say the DeVry degree was equivalent to an associates at a real school. Friends with a community college degree encountered the same issue with some bigger companies like Intel.
I’m not saying DeVry is a great school, but I later got a degree from OSU and it was no better…. just more expensive, slower and the facilities were much nicer.
Engineering as an “applied science”:
Science is more about collecting data to form models. Engineering occasionally requires this, but mostly it is something different entirely. Kind of like an apple is like an orange because they’re both fruit.
My parents designed there house in Microsoft Excel 2003.
