Dave finds a sweet Yamaha RX-V579 surround sound receiver with all the bell and whistles in the dumpster!
Not good enough for a numbered video.
40 minutes of Dave rambling about some bugs in the new Rigol MSO5000 scope in the Logic Analsyer, serial decoder, and possibly the Auto mode trigger system.
If you don’t like this style of rambling video, don’t watch.
NOTE: This is potentially a pre-production model and does not have the latest firmware.
Yes, I know the lighting and sound isn’t great yet in the new lab, working on it.
Awesome recreations of the Byte front covers

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.
