Dave shows you how to reverse engineering a PCB to get the schematic. In this case the new Rigol DS1054Z oscilloscope.
How does the discrete transistor analog front end and the software bandwidth limiting work?
How do you decode SMD transistor codes?
How does it compare to the old Rigol DS1052E?
Dave also discusses the low voltage ohms function of a mulitmeter, how it’s useful, and how to test your multimeter to see if it will have any issues with in-circuit testing.

Dave exposes the global White Van Speaker Scam and tears down a Marc Vincent Surround Sound Receiver, one of the items sold in Australia through this scam.
How crap is it?, watch and find out!
Also a 3D Optics HD-8500 projector that is also sold as part of the scam that involves the absolute cheapest quality parts sold under fake brands at grossly inflated prices from literally the back of a van.
