PWM Visual Explanation

Yesterday by simple serendipity I discovered that when the camera saturates with the power LED glow, it shows the duty cycle of the LED being PWMed, so I made this second video to show more PWM levels.
Also by calibrating the PWM frequency with the camera frames per second I managed to almost freeze the glow (in the first video it moved)

Hope you all like it.

Pulse width modulation. rtfmn.

[rodstartube]

very graphic

[thepazzo]

Inspiring.

somehow makes me think of bio-luminescent jellyfish and oceanic pulses. Cool to have a visual to compare and contrast with the dancing bubbles-great work keep it up

[UNOMINER]

just tell him its for a hydrogen generator lol everyone knows that

[pwmpower]

Very COOL, any chance you could provide a diagram?

[TexZK]

Wow, you can also see the duty cycle on the vertical lens flare :D

[RexHavok]

What's a PWM?

[Buma86]

lol, awesome and amazing

hi could you make a pwm that gives 42712.2hertz output standing wave constant if so i would buy one off you for an electrolysis experiment melwheatc at aol dot com my email

very cool
