Testing the new Tektronix 2 series waveform update rate vs older Keysight, Siglent, and Rigol scope, and a signal demonstration on how it matters.
And also how to measure the waveform update rate on your scope.
This is not a review, and was going to be a 2nd channel video, but people voted to have it one the main channel so here it is.

Dave takes a look at the Orange Pi One $10 single board 4 ARM Cortex A7 processor computer and compares it to the Raspberry Pi 2.
Coving the install of the ARMbian flavour of Debian.
Beware the security bug!
And what is the power/watt efficiency between the two?

Original video: https://www.youtube.com/watch?v=VGENVguQQmo
Timelapse install video: https://www.youtube.com/watch?v=fQAd7nposJQ
How much energy was produced?
How does net and gross metering work?
