Hi Dave
I have some suggestion for new video topic.
You have lot of measurement units and it's a pity don't use it.
What's about pick some project from blog like LNA or Soldering Station or simply garden watering and improve it's design.
It may be some "series" of videos but always something new regarding to measurement or design or another hints.
Maybe possibly that we can vote for next project;)
Regards BFX
