Rigol MSO5000 Bug Bonanza

tir, 04/12/2018 - 00:36

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.

World Exclusive!
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.

EEVblog #1144 – Padauk Programmer Reverse Engineering

man, 12/11/2018 - 00:37

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.
