I have had a long and interesting career as an electronics design engineer followed by an (unexpectedly long) second career as a school physics technician (I retired last year).
Early on, I was responsible for the design of some school physics equipment for the Nuffield Project. 50 years later I find myself working on a project (with a friend) to design another item of school physics equipment.
I became very dissatisfied with the accuracy of school physics textbooks and examination questions; so I started a blog: https://agrumpyoldphysicstechnician.wordpress.com
Initially this was a Feynmanesque rant but quickly became more of an alternative textbook.
