This evening I watched Are you the right person to design complex electronic boards? which discusses what being a professional electronics designer entails. I particularly liked this slide which compares and contrasts the books a hobbyist might read versus what a professional might read.

This project’s homepage is here: John’s wiki ยง Learning the Art of Electronics.

In this video we introduce a new feature of the show. In these segments we will be working through Learning the Art of Electronics.

We will be doing a total of 27 videos for this feature. 25 labs, this introduction, and a conclusion. Videos will come out on the first Tuesday of every month (hopefully!).

We did a new book teardown for this book last year: New Book Teardown #3: Learning The Art of Electronics: A Hands-On Lab Course (2016) | In The Lab. You can see in the comments a number of people encouraged me to make videos for this book, so that’s what we’re doing now.

Also a shout out to my mate over on Learning as a hobby for encouraging me to undertake this project.

10 Things I Wish I Knew When I Started Microsoldering

I really enjoyed watching this video: 10 Things I Wish I Knew When I Started Microsoldering. The ten things are:

  1. You can only learn by actually working on motherboards
  2. You can actually get good quality tools (for cheap) from AliExpress
  3. Just because a tool works well for someone else doesn’t mean it will work well for you
  4. 90% of good soldering comes from having an understanding how heat works and how heat dissipates
  5. All the pros that you see on YouTube are still learning too!
  6. Know your limits, there are some problems you can’t fix
  7. Some things aren’t worth fixing because of the time and effort and cost involved, but sometimes things are worth fixing just for practice and learning purposes
  8. BGA work isn’t as scary as it seems or is made out to be
  9. Buy your consumables in bulk
  10. Spend time learning from pros on YouTube!

Investigating better lighting for the bench

I was watching Remnants of the Capacitor Plague where they mentioned about these lights: 3 in 1 6W 6500K Industry Microscope LED Gooseneck Light Illuminator Lamp Spot Light Lamp Fill Light Lamp With 60 LED Ring. I wanted to know more so I asked about which ones the YouTuber purchased themselves. I hope I hear back! (And I may not hear back, it seems my question might have been flagged as spam, possibly because I included a link to AliExpress in the comment?)
