I seriously do not buy it until I try it. Chips usually have some bulk capacitance inside on the power rails but that´s just ridiculous... And the switching frequency is quite low.
And you are driving a whole LCD bus let alone the processor itself. Edit: Which as stated below could be powering the processor.
And it´s April first coming fast to Aussieland so... no... Something is up... It can´t be that nobody ever tried that before, I have been on the internets for a while...
No no no no no... I saw quite well how good your acting was on the Keysight video... no no no no...
Edit: Actually reading a character from the LCD and then going to sleep plus the PWM BS, could also explain the low PWM frequency... really good call from the guy below!
It is not diffusion capacitance. Diffusion capacitance is due to minority carrier storage of forward biased junctions. You are using the the reverse biased substrate junction capacitors. They are never forward biased.
You are lowering the current since the PWM is lowering the average voltage the microcontroller sees. The internal voltage will have a sawtooth edge.
So in this example processor is actually takes it's power from SPI/whatever lines from display board if I understand the joke right?

Good call! But that really depends on the LCD driver, you got to get the LCD in write mode for that to happen! Which of course it´s pretty reasonable!

Look what timezone Dave is in and what date it is in Australia..
Assuming that the internal capacitance would really allow that and ignoring all the problems associated: how would that differ from simply lowering supply voltage? ATmega328P has pretty linear dependency of current consumed and supply voltage. My bullshit sense is tingling.
Fascinating until I looked at the date.
Dave I think you do the best ones on you tube
He was like 3 hours early...
This sounds just like capacitive deractance at work
Its not just microcontrollers it works on.
I've been using this technique on my core i7 desktop, PWM'ing the power at 11.574 uHz
To be honest, I liked MickMake's video better.
I used to subscribe, but Mick hasn't posted since a year ago, anyone know if he's ok?
It can be done. Using the following device, you really can cut your electricity bills in half.
I smelled something fishy as soon as I noticed his DaveCad of the CMOS Inverter looked a little bass ackwards.
Looked more like a buffer, eah?
Plus.. My calender was close by..
Oh Dave, you get me every year. Although I worked this one out before the end of the video. Good work!
I have to admit: The Troll in the thumbnail was a dead giveaway.
But that might also be because i know those hideous things from when i was a child, they were all the rage back then.
But again i have to congratulate: You can get stuff like this across so professionally, that I can really believe them, being the layman that i am.
<insert the sound of slow clapping here>
I smelled something is wrong, but haven’t realized it’s April’s Fools. Dave got me. Good job.

When I first saw the video I thought it was a joke as my calendar had already ticked over to April 1st. But I am in NZ and and we are 2 hours ahead of Australia so it would have still been 31st March in Australia when Dave released the video.
