Positronic Brain Sim requires no MCU?
Costume Idea for Halloween
A Diamond Flashing LEDs Update I
D1 to D35 are diamond flashing LEDs. D36 and D37 are multicolor cycling LEDs.
Just a quick update to the diamond flashing LEDs. I hacked a USB cable and attached this as the power source. I also added some two lead colour-cycling LEDs (not shown on video).
A bit of fun and very pretty. It might be good as a baby mobile or a calming mood light - it's quite relaxing and almost hypnotic. I decided to make it as a "pick-me-up project" for those long winter nights in 2012. I'm now looking to use this idea to look like a positronic brain for halloween 2013 [positronic brain] inside a model of a human head.
The video speaks for itself. A very simple circuit with no MCU - the arrangement of led's makes the flashing pattern. I think it's the slightly different power requirements of the different colours that makes the pattern work.
Slowed down the video shows that red and yellow come on first before the pattern stabilizes. I'm not sure if this explanation of the pattern is correct. Please comment if you agree or not, or have any more ideas.
