A teardown and quick look at the new lower cost mid-range 70-350MHz Phoenix chipset based Rigol MSO5000 mixed signal oscilloscope, to be release on the 13th Nov. Stating at US$909.
How does it compare to the 7000 series scope just released 5 months ago?
Dave finds a 65″ 4K UHD LG LCD TV in the dumpster!
Will it work?
Bonus teardown included.
David looks at the pins on the Padauk PMS150 programmer for potential reverse engineering.
TLDR; It doesn’t look easy to reverse engineer this protocol, it’s messy with lots of voltage levels, as Padauk said it would be.
Just buy the programmer for now!
There is also a Flash/EEPROM re-programmable version of the chip, the PFS154C.
Check out the amazing increased working distance on the Eakins microscope using a barlow lens to get a larger working area.

A tour of the shambles that is the EEVblog lab, before the big move.
Using the Padauk programmer to program the 8 pin SO PMS154C micro and flash a LED on a breadboard.
Getting the 3 cent Padauk microcontroller to blink a LED.
Or at least the in-circuit emulator blinking a LED with C.
UPDATE: LCSC have just said that they will offer a free programming service for a limited time to anyone. Just email them when you place your order.
Well, repair-ish. Fixing the adjustment issue in the Systron Donner oven crystal oscillator. More issues found though.

Dave got a tip-off on a dumpster full of instruments, so raced off to check it out, what will he find?
Mailbag Monday, teardown bonanza!

A look at how the Banksy artwork prank “Girl with a Balloon” shredded itself moments after being sold for £1M at a Sotheby’s auction.
How long did it sit idle waiting to be triggered?, and was this actually possible?
NOTE: The Artwork was authenticated by “Pest Control”, which is Banksy’s own authentication house. If the artwork was delivered to them for checking before the auction, this is when they installed the mechanism. I still think the at least the seller has to be in on it, and likely the buyer (otherwise they could sue Banksy and bring his real name into the public). And if Sotheby’s were in on it (they’d lose their reputation if they were) they look like fools. Lose–lose for Sotheby’s.
How to turn a horrible unorganised schematic into a nice readable modular schematic with proper signal flow.
