   Keyzer didn’t finish detailing the costs associated with selling on Amazon.
   – Roughly $1k for trademark.
   – $?? for your own block of UPC #s.
   – 18% commission for fulfillment.
   – ??$$ Other?

   Saying economics pushes manufacturing out of Seattle is like saying weapons commit murder and not the person who wields it. Seattle/California’s notorious policies are an industrial form of gentrification.

   In regard to Altium and kicad… It doesn’t matter if the tool is free if I can’t open a file because I can’t recall what version it was originally made in. Even if I knew what version, if I had to download that version…. just NO.

   Rober’s audience aren’t engineers. They’re mostly enthusiasts who assume they’re going to learn “the practical parts of engineering” by taking this course. Unfortunately the course is mostly just subjective junk that actual engineers learn by doing a couple projects. No refunds to figure this out either. Rober appears to have figured out that he needs a paying community in order to grow.

     I agree, you got a point there George about the audience of these kind courses they talked about. However, I think people like Rober (Also Dave and Chris to some extent) need to make a bitter sweet choice of appealing to the engineers or hobbiest. I am glad that the amphour’s content sballanced between both groups.

   I probably started listing to the amphour like 3 weeks before 2020 and since that i never missed an episode
   It is really awesome to know the knowledge you can get from engineers goofing around
   Keep it up

3. Yep, Altium changes are a pain, I use the tool since 1998 and version upgrades usually where no big deal.

   I made the mistake of making the upgraded when the workload was very low during the pandemia, but then it increased and had to work on in 7 designs in a very short time frame. That was not the issue, the issue was that with the upgrade my productivity whent to the drain together with my holiday break.

   You can spent hours looking how where the option is located, or how to do this or that that it was usually very simple. Or a particular feature does not exist anymore.

   Saludos !!
