eevBLAB #65 - No Professional Engineer Title For You!
Victoria Australia just passed the Professional Engineers Registration Bill 2019, a bill that makes it illegal for unregistered engineers to call themselves a Professional Engineer!
Go Back to the Future with Dave to 1985 as he tears down the world's first Video 8 camcorder, a vintage Sony CCD-V8AF

Dave demonstrates how to add testing capabilities to your PCB panel for easier production testing. Using an example of his new uCurrent design, and also a commercial product designed to be automatically ATE tested.
Essentially Part 3 of the PCB Design For Manufacture series.

A teardown of a very interesting bit of optometry kit, a Shin Nippon NVISION K-5001 RefKeratometer (Auto Refractor Keratometer).
It can measure the curvature of your cornea, and well as refractive error to diagnose near and far sightedness.
