You offer an intellectual deep dive into the most amazing gadgets and the like of life. I truly enjoyed your series on the pinball machine you had, that was actually very VERY in detail, and I'm very glad you take the time to record yourself working. I do the same thing, I'm just entirely too shy to share it with the world as you do. Thank you for doing that.
